Launch preparation

In the last post I talked about hydrographic surveying, the software used and the multibeam echosounder on the survey boats (called launches). The software is setup in the cabin by the hydrographer in charge. It takes a good five minutes to get an accurate read from the GPS (global positioning system) receiver. Then it takes time for the IMU (inertial measurement unit) to respond and start to read the boat’s heave, pitch, roll, yaw, and heading values.

launch data storage
The four Fairweather launches have the same, high-end technology in their cabins used to collect data from the multibeam echosounder, CTD sensor, a sound speed system, and a positioning and altitude system.

Often, the launch drives in a circle eight in order for the positioning receivers to be “seen” by the satellites, as a  stationary object is more difficult to detect than one that is moving. Setting up the day’s project using the multibeam echosounder software also takes some time but all the steps need to be done properly and to the correct specifications prior to starting the sounder. If not, the locational data will be wildly off and the depths inaccurate.

Another task that must be done from the launch before starting to transect is to test the salinity and water temperature using a CTD probe, which is called a cast. I mentioned this in a previous post. CTD stands for conductivity, temperature and depth. In the general area where the launch will survey, the CTD drops slowly to the bottom of the seafloor, collecting data that will be fed into the hydrographic program. Salinity and temperature at different depths will slightly change the rate at which sound travels in water. Again, the CTD process makes the location and depths as accurate as possible and must be done.

Casting the CTD probe into the survey location to get conductivity, temperature and depth readings.

Usually, the chief hydrographer sets the defined area to be transected for the day and this is usually a polygon. The launch will sweep with the multibeam echosounder the outside lines and then scan at parallel set distances between the lines, either in a roughly north-south direction or a roughly east-west direction. For this particular hydrographic project, coverage of survey lines can be spaced at about 400 meters apart or greater apart depending on the depth. Recall that the nautical chart of Bristol Bay from the last post showed soundings dotting the area. Solid bathymetric coverage is not always needed on these projects. The Cape Newenham area has proven to have gradually varying depths and is mostly quite flat so free from obvious obstructions like large boulders and sunken ships. 

Once the technology setup is complete in the cabin, the hydrographer shares the map window with the coxswain (the person in charge of steering or navigating the boat). The hydrographer sets the points and the lines so that the coxswain knows where to direct the launch. And by direct, I mean the coxswain uses compass direction and boat speed to get from place to place for the survey. And the hydrographer in charge turns the echosounder on and off when the launch is in position or out of position.

Coxswain
The coxswain navigates the survey line set by the hydrographer in charge.

Because the transects run parallel to each other and are equally spaced apart, the hydrographers call this technique “mowing the lawn,” (see video below) for they are essentially mowing the surface of the ocean while the multibeam echosounder is collecting soundings of the surface of the seafloor.

A day out on a launch will go from about 8:30am to about 4:30pm but sometimes an hour or so later. If the Alaskan weather is cooperating, the hydrographers want to do as much as they can while out on the launch. Once surveying is complete for the day, the hydrographer in charge has to close up and save the project. Then data get transferred to the larger workstations and shared drive on the Fairweather.

Meg on launch
Every day on the launch, at least on this leg, has been great with perfect weather. And today, the added bonus for me was the phenomenal geology as we surveyed right along the shore.

I’ve taken loads of photos and video while at sea. I have tried to post just those pictures that help explain what I’ve been trying to say in the text. I haven’t posted any video on here as the internet on the ship is very weak. These next photos are a tour of different parts of the NOAA Ship Fairweather.

The good folks of Ship Fairweather like to have a nice time every now and again, so they set up evenings, about once a leg, to have Finer Things. People come by, bring fine cheeses, fine chocolates, fine almonds, fine fig jelly, and fine maple sugar candy from Rhinebeck, NY, and have a fine time. And a disco ball.


Did You Know?

Inertial Measurement Units (IMU) technology that is so important for accurate hydrographic survey mapping was developed by the U.S. military. IMUs were used in the development of guided missiles, unmanned aerial vehicles (and now drones), battlefield reconnaissance, and target practice.

While at port in Seward, it has already been my pleasure to meet some of the people that make up the team of NOAA Ship Rainier.  My mission so far has been to learn about the different capacities in which individuals serve on board the ship and how each person’s distinct responsibilities combine together to create a single, well-oiled machine.  

The five main departments represented are the NOAA Commissioned Officers Corps, the Hydrographic Survey Technician team, the Engineering team, the Deck department, and the Stewards.  There are also a few visitors (like me) who are here to observe, ask questions, and participate in daily operations, as possible.

Career Focus – Hydrographic Survey Technician

Today I spent some time with Survey Technician, Amanda Finn.  Amanda is one of nine Survey Techs aboard NOAA Ship Rainier.

What is hydrography?

According to the NOAA website, hydrography is the “science that measures and describes the physical features of the navigable portion of the Earth’s surface and adjoining coastal areas.” Essentially, hydrographers create and improve maps of the ocean floor, both deep at sea and along the shoreline.  The maps, or charts, allow for safer navigation and travel at sea and are therefore very important.

(Click here to see the chart for Resurrection Bay, where the ship is currently docked.)

 

What does a Hydrographic Survey Technician do?

Technicians like Amanda are in charge of preparing systems for collecting hydrographic data, actually collecting and processing the data, monitoring it for quality, and then writing reports about their findings.  They work part of the time on the ship as well as on the smaller launch boats.

 

What kind of data do Survey Techs use?

Both the main ship and the small launches are equipped with multibeam sonar systems.  SONAR is an acronym for Sound Navigation and Ranging. This fascinating technology uses sound waves to “see” whatever exists below the water.  Instead of sending out one sound wave at a time, the multibeam sonar sends out a fan-shaped collection, or swath, of sound waves below and to the sides of the boat’s hull. When the sound waves hit something solid, like a rock, a sunken ship, or simply the sea floor, they bounce back.  The speed and strength at which the sound waves return tell the technicians the depth and hardness of what lies beneath the ocean surface at a given location.

It is possible to be overwhelmed in a good way.  That has been my experience so far traveling from my home in Georgia to Alaska.  The ship is currently docked at the Seward shipyard in Resurrection Bay. When you hear the word “shipyard”, you might not expect much in the way of scenery, but in this case you would be absolutely wrong!  All around us we can see the bright white peaks of the Kenai Mountains. Yesterday I stood in one place for a while watching a sea otter to my left and a bald eagle to my right. Local fishermen were not as enchanted as I was, but rather were focused on the task at hand: pulling in their bounties of enormous fish!

I am similarly impressed with the order and organization aboard the ship. With over fifty people who need to sleep, eat, and get things done each and every day, it might seem like an impossible task to organize it all.  By regular coordination between the departments, as well as the oversight and planning of the ship’s Commanding Officer and Executive Officer, everything flows smoothly.

I think that it is worth noting here how the level of organization that it takes to run a ship like NOAA Ship Rainier should not be taken for granted.  Every individual must do their part in order to ensure the productivity, efficiency, and safety of everyone else.  As a teacher, we often discuss how teamwork is one of life’s most important skills. What a terrific real-world example this has turned out to be!

Seward is located on the Kenai Peninsula in southern Alaska.  The name Kenai (key-nye) comes from the English word (Kenaitze) for the Kahtnuht’ana Dena’ina tribe.  The name of this tribe translates to “people along the Kahtnu river.” Click here for more information about the Kenaitze Indian Tribe.

Science and Technology Log

This afternoon I spent an hour with Chief Marine Engineer, Thom Cleary. As promised, he gave me a tour of the Engine Room. Thom arrived on the Thomas Jefferson in 2011 and has worked not only on maintaining operations, but greatly improving them. When asked about his favorite ship mechanism, he responded with one that is not his favorite but of which he is most proud. The Thomas Jefferson, along with most other ships, typically used to rid greywater and sewage by offloading into the ocean. The EPA states that ships must be at least one nautical mile from land or people in the water and three nautical miles from aquaculture (2018). With hydrographic survey operations taking place in “no discharge” areas (close to shore), this could complicate and/or slow down the Thomas Jefferson’s progress.

Realizing the inefficiency and in an effort to improve, Thom investigated other options. It was decided that a fuel storage tank would be converted to hold more wastewater. After a long wait period, the new method was installed. Within the first season 38,000 gallons of sewage was stored and discharged to a shore treatment facility. Today, the tanks have gone almost two months without release into the Gulf of Mexico. This improvement has allowed hydrographic operations to continue without interruption, conserves fuel, and increases efficiency.

Renovations to the Thomas Jefferson did not stop there. Originally constructed in 1991, the ship has room for many other improvements. Thom and team advocated for all natural lubricants (rather than petroleum), switched all light fixtures to LEDs, and adjusted the ballast system. In 2016 the roughly 122,000 gallon ballast system changed from using sea to municipal water. This now allows the ship to move from multiple coastal waters without concern for carrying invasive species in the ballast tanks. In addition, the new waste water tank was strategically placed in the center of the ship to help with stability.

Thom is an innovator and self-described incorrigible tinkerer. Many of these changes would not have been made without his (and team’s) desire and advocacy to make things better. When I asked if these upgrades were standard on ships, he mentioned that the Thomas Jefferson is a trailblazer.

CO (Commanding Officer) authorized a launch on one of the boats. After some mishaps with a fuse, the crew performed multiple safety checks and we were cleared to go. Mission: collect survey data near a stationary platform. CO’s comfort level to obstructions with the main ship is a half-mile, so having the smaller launch boats is helpful when surveying areas like this.

While cruising out to the survey area, I spoke with Pat Osborn, part of the Thomas Jefferson’s deck crew and our survey line driver for the day. Pat has two years of training and was explaining that he is still learning parts of his job. (Everyone on the ship wears multiple hats.) He spoke highly of his job and appreciated the multi-dimensional relationship between CO and the crew. Pat explained that CO is not expected to be an expert in all areas of the ship- there are safety checks (such as preparing for the launch) where the CO asks lead crew members to evaluate and sign-off prior to action. Every mission I’ve observed and attended has proceeded in this manner. It is a highly respectful and safe environment.

This information is used for analyzing the survey data. On the ship, this information is collected using an MVP which allows the ship to stay in motion.

As soon as we had the survey equipment set up and running, survey technician Kevin Brown brought out a fishing pole. I hadn’t realized that we could fish while out on the boat! We proceeded to catch and release about 10 tuna (likely False Albacore and Bonito). Kevin reeled in two, then passed the pole to me. I couldn’t believe how hard it was to real in a fish. I was reading that they can stay on the line and swim up to 40 mph!

Science & Technology Log

Over the past two days I have been introduced to tremendous amounts of the science of hydrography. In this blog post I will focus on the hardware used and the process of surveying. There are two types of sonar that are being employed. The first is side scan sonar and the second is multibeam sonar.

Side Scan
Side scan array sonar housed underneath one of the small launch vessels

 

Side scan is shorter range and performs better in shallower water. Side scan is used in conjunction with multibeam, however, as side scan does not give true depth values. The function of side scan is to show features evident on the ocean floor. For this reason, multibeam is run in conjunction with side scan in order to keep an accurate record of depths.

Multibeam
Multibeam sonar housed underneath another of the small launch vessels

Multibeam shows an exact depth. Due to the fact that it is an angular spreading band from the center of the underside of the launch, at shallow depths it will only show a very narrow strip of ocean floor.


Stop and imagine…a lit flashlight shining on a wall from only a few centimeters away. What happens to the image on the wall as you pull the flashlight back? The area of coverage of the image will become larger. The concept is similar for the multibeam in shallow versus deeper water.


Using multibeam in shallow water then would create a need for more passes closer together in order to cover an area. There are instances where using this technology even in shallow water would make sense, but for a full coverage survey, this would not be the case.

CTD Image 2
A CTD; it contains sensors for conductivity, temperature and density of the water column

The third piece of hardware used for the standard small boat launch hydrographic surveys is the CTD device. The CTD will measure conductivity of the water and also give both a temperature and density profile. The CTD is deployed multiple times during a survey as a tool to calibrate the data that is coming in via the sonar. Conductivity of the water gives an estimate of the total dissolved solids in the water. This information, along with the temperature and density will give an estimate of sound speed through the water column.


Stop and try this one for better understanding… knock on a door normally with your head roughly arm’s distance from the point where you are knocking. Now repeat the process of knocking, but with your ear pressed against the door approximately an arm’s length away from the knock. What is different? You should have noticed that a more precise (and typically louder) sound reached your ear. If you pay close attention, you will also notice that the sound reaches your ear more quickly. This is roughly analogous to how changes in the water column will affect sound speed.


The final piece of equipment used regularly for surveys is a HorCon (horizontal control) station. This is a land-based station that will help to define accurate position in the water. It allows for greater precision with global positioning data. The signals of satellites responsible for global position are affected daily by changing atmospheric conditions. Moreover, the precise positions of the satellites themselves are actually not well known in advance. This may result in a GPS location moving a few centimeters in one direction or another. While this is not going to heavily impact your ability to find a Starbucks in a strip mall, it can have a definite impact on the accuracy of charts for navigation. The HorCon station always remains in the same place on land, and can therefore be used to calibrate the measurements being read in the survey waters nearby and that information can be used along with corrected satellite positions since it is coming after the fact.

Port Clarence chart
A nautical chart of the Port Clarence and Grantley Harbor area where we were surveying

Today we worked in Port Clarence, Alaska, both outside and inside of Grantley Harbor. Most of the depths being surveyed are in the 4-6 meter range. The particular area being surveyed had been previously surveyed in the 1950s by the US Coast and Geodetic Survey, likely using a single beam sonar system. The current survey is intended to note changes that have occurred since that prior survey and to accurately update all of the charts. The area of western Alaska is expected to increase in boat traffic over the coming years due to the opening of the Northwest Passage from the Pacific to the Atlantic via the Arctic. This route is significantly shorter for most shipping traffic than the route through the Panama Canal. Because of this expected increase in traffic, there is a need to identify areas for sheltering during heavy seas. Port Clarence is a natural inlet that offers some protection and holds potential for this purpose.

The process of surveying:
Two launches were deployed. I was on launch 2808, the second described here. The first was equipped with only multibeam sonar and the second had both multibeam and side scan. The plans for the two launches were different. The launch with only multibeam was working in an area of Grantley Harbor and covering an area that had previously been mapped to insure that the values were acceptably accurate. This focus existed primarily because of extra time available up in this area. The launch running the side scan was completing some unfinished work in Port Clarence and then did further work inside of Grantley Harbor. These areas, or “sheets” are described below. As a side note, small boat deployment is a fascinating and involved activity that I will discuss in a later blog.

Survey areas are broken up into sections known as “sheets” – each sheet has a manager. This person will be from either the NOAA Corps or a civilian member of the scientific survey team. The sheet manager will be responsible for setting up the plan for survey and doing all of the final checks after data has been gathered, cleaned and examined to determine if there are areas that should be rechecked or run again before it is completed and undergoes final processing.

A sheet manager will need to consider several questions prior to setting up the initial parameters for the survey. What is the depth being surveyed? What type of bottom is it? What type of coverage is needed? All of these factors will come into play when determining how the lines will be run – how long, how far apart, which sonar type, etc.
Once the plan is determined, it will be the job of the Operations Officer, LT Damian Manda, to parse out the duties and create a daily work plan to cover all of the areas. Each day, multiple launches will be sent out to gather data as described above. As the fieldwork finishes for the day, data will be transferred to a drive and then brought into the ship’s mapping room where night processers will begin the lengthy work of checking and cleaning the data so that it can all be ready for the final processing step prior to being sent to the client.

How good are those data?
There are several checks built into the data collection process. First, the survey team members on the launches are watching in real time. With three screens to work from, they are able to see what the sonars are seeing and can also set certain limits for the data that will alarm when something appears to be contrary to what’s expected. Night processors look for anomalies in the data like sudden inexplicable drops in depth in an otherwise flat surface or an extremely “noisy” area with little good data. Any area with a former survey will also be compared to the previous values with large differences signaling possible issues. Many trained eyes look at the data before it is accepted for charting and there will commonly be at least one return to an area to check and recheck prior to completion. One area in the current survey has continued to show odd results, so trained NOAA divers will dive the area to find out what is really going on.

Personal Log

So far this has been an amazing experience. I fully enjoy being among the crew of the Fairweather and living on the ship. It’s hard to say what my favorite part has been so far because I have honestly enjoyed all of it! Since we didn’t get underway until Monday, I had the opportunity on Sunday to roam around Nome with a couple of the other folks that are just here for two weeks, LT Joe Phillips and LCDR Ryan Toliver. I learned a lot more about both the NOAA Corps and the Public Health Service of which they are respectively a part. (These are two of the seven uniformed services – can you name the other five?) NOAA Corps officers are in command on all of the active NOAA commissioned ships and aircraft and you will learn a lot more about them in future posts. The PHS is an organization made up primarily of medical professionals. These folks serve in various medical and medical research positions around the nation. There are many who will work for the National Institutes of Health in research, or the Bureau of Prisons or commissioned vessels like Fairweather as practitioners. Unlike NOAA Corps, PHS is not on a billet cycle where every two to three years you will be moved to a new position in a different office or location. Similar to all of the other uniformed services, though, promotion through the ranks is both encouraged and desired.

Traditional Boat - Nome
As we walked all around Nome, this was one of the sights – the frame of a traditional fishing boat.

We also saw the marker for the end of the Iditarod race. I was able to see the historic beginning in Seward, Alaska back in 2010, so seeing the end in Nome was an unexpected treat. Nome also has Cold War-era missile early warning system arrays at the top of a mountain nearby. We had a chance to hike around them and see some of the interesting geologic features of the area. There’s so much more to talk about, but I think I’ll stop here and save shipboard life for my next post.

Did You Know…

… that the Iditarod has its historic beginnings with the Public Health Service? There were many children in interior and western Alaska dying of diphtheria in the early 1920s. When it reached epidemic proportions, the only doctor in Nome reached out to the PHS in the lower 48 to ask for help. Vials of serum were found and sent north to Seward, but then because of heavy ice and storming, dog sled teams were used to get the vials to the interior towns and to Nome. The original race along the Iditarod Trail was run as a memorial to the “Serum Run” and eventually evolved into the highly competitive race it is today.

Science and Technology Log:

The role of the Fairweather is to conduct hydrographic surveys in order to acquire data to be used in navigational charts. While the Fairweather has sonar equipment and collects lots of data in transit, much of the data collected on a daily basis is by using smaller boats, with a rotating crew of 3-4 people per boat. The Fairweather will sail to the research area and drop anchor, and for multiple days crews will use these smaller vessels to collect the raw data in an area.

 

“Sonar” was originally an acronym for Sound Navigation and Ranging, but it has become a word in modern terminology. The boats contain active sonar devices used by the NOAA scientists to calculate water depth, document the rocks, wrecks and kelp forests, and in general, determine hazards to boats. Ultimately their data will be converted in to navigational charts – but there is a significant amount of work and stages to be undertaken to make this a reality.

Attached to the small boats are Kongsberg Multi Beam Echo Sounders (MBES). These devices emit sound waves in to the water. The waves fan out and reflect off the bottom of the sea floor and return to the MBES. Based on the time it takes for the MBES to send and receive the sound waves, the depth of the sea floor can be calculated. As the boat moves through the water, thousands of pieces of data are collected, and collectively a picture of the sea floor can be built.

IMG_0356
The pink line is the sea floor

It sounds simple, right? But I am beginning to understand more about the complexities that go in to a project of this scope. It would seem simple perhaps, to drive a boat around, operate the MBES and collect data. As I have quickly come to understand, there is a lot more to it.

As mentioned before, due to the weather conditions in the geographic area of study and routine maintenance, the Fairweather has a field season, and a dry dock season. During the non-field season time, data is analyzed from the previous seasons, and priorities and plans are made for the upcoming seasons. Areas are analyzed and decisions made as to which regions the Fairweather will go to and sheets are determined. A sheet is a region within the project area. Each sheet is broken up in to polygons. On any given day, one small boat will cover 1-3 polygons, depending on the weather, the complexity of the area, and the distance of travel from the Fairweather.

 

There are many parameters that the scientists need to consider and reconfigure to acquire and maintain accurate data collection. A minimum density of soundings (or ‘pings’) is required to make sure that the data is sufficient. For example, in shallow waters, the data density needs to be a minimum of five soundings per one square meter. At a greater depth, the area covered by the five soundings can be 4 square meters. This is due to the fact that the waves will spread out more the further they travel.

A coxswain will drive the boat in lines, called track lines, through the polygon. As the data is collected the ‘white chart’ they are working with begins to get colored in. Purple indicates deepest water. Green and yellow mean it’s getting less deep. Red indicates shallow areas, and black needs to be avoided. In the pictures below you can begin to see the data being logged visually on the map as the boat travels.

 

Make an analogy to mowing a lawn. There are areas of most lawns where it is easy to push the lawnmower in straight lines, more or less. The same can be said for here, to some extent. In the deeper waters, not close to shore, the boats can ‘color in’ their polygon using relatively wide swaths that allow the sonar data to overlap just slightly. Every time the boat turns to go back in the opposite direction, the MBES is paused, and then started again once the boat is in position, making a new track line. Close to the shore, referred to as near shore, there are usually more hazards. In these areas, speed is slowed. Due to the increased potential of rocks and kelp beds in an unknown area, the boats do something called half-stepping, in-effect overlapping the ‘rows’ – think about re-mowing part of that section of lawn, or mowing around tree trunks and flower beds. As a visual image comes up on the screen, the coxswain and the hydrographers can determine more where their next line will be and whether they should continue surveying that area, or if there are too many hazards.

Data aquisition

Full coverage needs to be achieved as much as possible. At times this does not happen. This can be as the result of several factors. Kelp increases the complexity of data collection. Kelp often attaches to rocks, and there are large ‘forests’ of kelp in the areas being surveyed. As the sonar also ‘reads’ the kelp, it’s not possible to know the true location, size and depth of the rock the kelp is attached to, and in some instances, to determine if the kelp is free floating.

Kelp

Steep slopes, rocks and kelp can also create ‘shadows’ for the MBES. This means that there are areas that no sounding reached. If possible the survey team will re-run a section or approach it from another angle to cover this shadow. At times, the rocky areas close to shoreline do not allow for this to be done safely.  A holiday is a term used by the survey crew to describe an area where data did not register or was missed within a polygon or sheet. During data collection, a day may be dedicated for boats to return to these specific areas and see if the data can be collected. On occasion, weather conditions may have prevented the original crew from collecting the data in the first place. Equipment malfunction could have played a role, as could kelp beds or hazardous rock conditions.

Survey crews are given several tools to help them navigate the area. Previous nautical charts are also superimposed on to the electronic chart that the surveyors are using. While many of these contain data that is out of date, it gives the crew a sense of what hazards in the area there may be. Symbols representing rocks and kelp for example are shown. The Navigable Area Limit Lines (NALL) are represented by a red line that can be superimposed on the map. Any area closer to shore than the NALL is not required to be surveyed.

 

 

IMG_0315
The red line is the Navigable Area Limit Line. Areas inland of this line do not need to be surveyed, as they are known to be entirely non-navigable.

On occasion, surveying will discover a Danger to Navigation (DTON). This might include a rock close to the surface in a deeper water area that is not shown on any map and which may pose imminent danger to mariners. In these instances these dangers are reported upon return to the Fairweather, and information is quickly sent to the Marine Chart Division’s Nautical Data Branch.

During the course of the day, the scientists are constantly checking the data against a series of parameters than can affect its accuracy. Some of these parameters include temperature, salinity of the water and the tide levels. More about these parameters will be discussed in later blog postings.

Personal log

The first part of the day involves the stewards getting coolers of food ready for the survey crew who will be gone all day. The engineers have fixed any boat issues from the previous day and re-fueled the boats and the deck crew have them ready to re-launch. A GAR score is calculated by the coxswain and the crew, to determine the level of risk for the days launch. The GAR score examines the resources, environment, the team selection, their fitness, the weather and the mission complexity. Each factor is given a score out of 10. Added up, if the total is 23 or less, the mission is determined ‘low risk’, 24-44 is ‘use extra caution’, and greater than 45 is high risk. On the first day I went on a boat, as a first timer, the GAR score was a couple of points higher in the ‘team selection’ section as I was new.

Operational Risk Assessment Form

Another fascinating aspect of this research is the equipment on the ship needed to launch these small boats. Huge winches are needed to hoist the boats in and out of the water. Deck crew, with support from the survey crew are responsible for the boat hauling multiple times a day, and the engineers are on hand to fix and monitor the equipment.

After my first day out on the small boats, the data acquisition began not only to make more sense, but also my understanding of the complex factors that make the data collection feasible began to broaden. I had naively assumed that all the work was done from the Fairweather and that the Fairweather would be constantly on the move, rather than being anchored in one location or so for a few days. As we journeyed around small islands covered in Sitka spruce, I watched constant communication between the survey crew and the coxswain on the small boats. The survey crew are constantly monitoring the chart and zooming in and out so that the coxswain can get a better and safer picture of where to take the boat.   As well as watching the monitors and driving the boat, the coxswain is also looking ahead and around for hazards. There is a significant number of large floating logs ready to damage boats, and on occasion, whales that the boat needs to stay away from. It is a long day for all the crew.

Aside from learning about the data acquisition being on the small boat, one of the joys was to be closer to some of the wildlife. While I will go in to more detail in later entries, highlights included catching glimpses of humpback whales, families of sea otters, and harbor seal pups.

Fact of the day: 

While animals, such as bats, have been using sonar for thousands or millions of years, it wasn’t until the sinking of the Titanic that sonar devices were invented and used for the locating of icebergs.  During World War I, a French physicist, Paul Langévin, developed a tool to be able to listen for submarines. Further developments lead to sonar being able to send and receive signals. Since then, major developments in sonar technology have led to many different applications in different science fields.

Word of the day: Nadir

On small boat surveys, nadir is the term used to describe the ocean floor directly below the boat. It is the low point below the boat.

Hello again!

Science and Technology Log:

One important thing that every single person has to face, no matter how old they are or what kind of job they have, is what to do when things go wrong. We are always happy when things are going smoothly—but what do you do when they don’t?

I found out about how important it is to be a thinker and problem solver on the Thomas Jefferson because we are experiencing engine problems. First the launches were not running. Then the TJ’s engines were having difficulties and it was discovered that we had water in our fuel. The engineers and officers all started to ask questions: Where is the water coming from? Is there a problem with the tanks? How are we going to fix this situation? What is the best solution right now? It was determined that we should sail into the Naval Base in Newport, Rhode Island so the fuel could be pumped out and the fuel tanks examined. This is a big job!

We sailed into Newport on a beautiful sunny afternoon. I got to spend some time on the bridge and watched as Ensign Seberger and GVA (General Vessel Assistant) Holler steered our large ship around obstacles like lobster pots and small sailboats. AB (Ablebodied Seaman) Grains acted as the look out, peering through binoculars and calling out directions in degrees (instead of feet or yards), and port and starboard (instead of left and right). LTJG Forrest explained how to chart the route to Newport using a compass, slide rule and mathematical calculations. His computations were right on as he plotted the course of the Thomas Jefferson.

When we arrived at Newport, the tugboat, Jaguar, needed to help us dock and then the gangway was lifted into place using a crane.

Now we are waiting in Newport to see how the ship will be repaired, and how that will impact the surveying mission and the work of all the scientists on board. The fuel is currently being pumped out of the tanks so the engineering department can figure out what is going on.

Personal Log:

Some of my students have emailed to ask where am I sleeping. When you are aboard a ship, you sleep in a stateroom. I have the bottom bunk and my roommate has the top. We have storage lockers and shelves to hold our stuff. The bathroom (called the head) connects our stateroom with another room.

I am talking with the HIC about the notations on the nautical chart for our survey grounds.

Science and Technology Log

As promised, today’s post is going to be about the Hydrographic Survey Launches. The Thomas Jefferson has two of these boats that are generally launched by 8:00am and return to the ship at 5:30pm. On Tuesday, my official role was Hydrographer in Training. I joined HIC Todd and Coxn Junior for a day of surveying on boat 3102. After a morning of seasickness, they returned me to the TJ around 11:30 to recuperate. However, I was still able to experience a little of what they do every day and the hilarious camaraderie between the two!

In general, the survey launches do the same work as the Thomas Jefferson, just on a smaller scale. The TJ can only drive on lines with a minimum depth of 30 feet, but the survey launches can go to a minimum depth of 12 feet which allows them to get much closer to shoals and the coast. Every morning, the launch survey teams have a meeting with the FOO and XO in the survey room to discuss logistics and safety. My boat was headed out to survey grounds on a new sheet near Cape May, New Jersey. Specifically, we were driving lines in the Prissy Wicks Shoal. This particular region has highly variable depths and created quite a challenge for the HIC and Coxn for two reasons: you cannot navigate in straight lines over shoals, and the shoals constantly change so you must drive slowly in case an area is shallower than charted.

HIC Todd
Todd is at his workstation in the cabin.

Todd has been a HIC for both the Rainier and the Thomas Jefferson. In this position, he was worked with many Teachers at Sea, and gave me lots of great resources to bring back to school. The HIC sits inside the cabin and makes sure that all of the equipment is working together and logging the correct data. Just like on the ship, he has an MBES, HYPACK, and POS-MV to help him do his job. However, unlike the ship, he does not have an MVP, and must launch a CTD every four hours to measure the sound velocity profile in the water column. Measuring the sound velocity profile is an important part of correcting the MBES data for improved accuracy. Remember, the equipment is very sensitive to changes in the water because the farther the sound waves travel, the more they are affected by changes in the density of the medium through which they travel.

Coxn
Junior is doing his best to keep us on the line

Junior’s job as Coxn is to work with the HIC to safely navigate the boat on the survey lines. The Coxn has a monitor controlled by the HIC to help him see the current chart and line. Junior gave me the opportunity to try driving, and I barely lasted 15 seconds before I was off the line! Tuesday was particularly complex because we were in a highly trafficked waterway, shoals appeared out of nowhere, and there was a very strong current around the cape. When another boat appears in the line, the Coxn must bring his boat to a standstill while staying on the line so that data collection does not have to stop. If the survey line goes over an area that is particularly shallow, a decision needs to be made about how to get around the shoal without hitting the bottom. A lot of good-natured yelling happens between the Coxn and HIC so that they can hear each other and be in constant communication.

Once the survey launch has returned to the main ship, the data is downloaded onto a server from which the hydrographers can move the data into CARIS. Eventually all of that data will be turned into a new nautical chart to help marine vessels maneuver through the waters.

Personal Log

Well, my bout of seasickness started about half an hour into my time on the survey launch. I started off in the cabin with the HIC, and the swells in the water got to me immediately. I spent the rest of the time on the deck with the Coxn trying to keep my eyes on the horizon. Through it all, I still managed to get a glimpse of some dolphins playing in the swells and saw many different types of boats and ships sailing around. When I was returned to the ship, I immediately felt better. However, the medical officer took precautionary measures and measured my blood pressure (totally normal, as usual for me) and prescribed 1.5 Liters of water before bed for the night. I took a nice long nap, and woke up in time for a delicious vegetable casserole for dinner. I am feeling back to 100% today, and hope to stay awake tonight. The TJ runs 24 hour operations, so I will pop by the bridge and survey rooms to see what it looks like after dark.

Science and Technology Log 

The past few days have been “typical” Alaska weather—fog, drizzle, moderate winds.  This morning I was quite surprised when I looked out my stateroom porthole.  The weather was supposed to have calmed somewhat overnight; however, it was obvious that a good blow had picked up. White caps covered the water’s surface. I was scheduled for a launch, RA-4 (each of the launches has a number 1-6, RA being the abbreviation for Rainier), but I decided not to board at the last moment.  When the launches are lowered to the side of the ship, the bow and stern (front and back) are secured with line to minimize movement.  To board the launch, you have to step across a 1-2 foot gap from Rainier to the launch. Today’s conditions amplified the heaving and pitching motion of both the ship and launch and made the distance between too far for my short legs.  I chose safety over adventure today.

As the launches continued to be deployed, Rainier began to transit from our anchorage north of Wosnesenski Island to our previous anchorage position in a small cove off the southwest corner of Ukolnoi Island. Having the flexibility to change the ship’s direction was essential for the safe deployment of launches today.  Personnel and equipment could be protected from the force of the wind and waves (which topped 6’ at times).  Although disappointed that I did not make it onto my launch, I was given an opportunity to watch the deck crew in action. I learned that this morning’s weather was some of the worst that the crew has seen during this survey season, however, work can be completed in conditions that are more blustery than today.

As a member of a survey team, you have to put your trust in the deck crew and their talents and skills. Jimmy Kruger is the Chief Boatswain. He is in charge of the deck and its crew. In a way, he is like the conductor of an orchestra—he makes sure that each member of the crew is in the right place at the right time and that they begin their job at precisely the right moment.   As the day progressed, I began to wonder how the weather data from 0700 to 1400 (2 pm) changed, so I took a walk up to the bridge. My guess was that, although there were still whitecaps on the surface, wind speed and wave height would have decreased, since we had anchored on the south shore of one of the islands (which would serve as a buffer from the wind).  It seemed to me that the weather was so much worse this morning.  Not so. The wind speed had actually increased by a few knots, although the seas had decreased by about a foot. When I am up on the bridge, I always find something new to inquire about.  It’s a busy place—not necessarily busy with numbers of people, but with instruments, charts and readings. General Vessel Assistant Mark Knighton and ENS Jon Andvick were on the bridge.

We sought a better anchorage southwest of Ukolnoi Is. when a 30 knot wind picked up. White caps cover the surface, the flag blows straight out facing aft.
We sought a better anchorage southwest of Ukolnoi Is. when a 30 knot wind picked up. White caps cover the surface, the flag blows straight out facing aft.

When you are standing on the bridge with a gusty wind coming at you, you immediately think of the anchors.  Rainier’s anchors are made of steel.  They weigh 3,500 lbs. EACH!  The anchors are attached to the ship by a very thick chain.  Chains are measured in a unit called a shot. A shot equals 90 feet, and each of Rainier’s shots weighs about 1,100 lbs.  There are 12 shots per anchor. (So, can you calculate the approximate weight of the total of Rainier’s shot? How about the total length of the chain?)  The depth of this small cove is between 9-10 fathoms.  This is important in determining the scope, or ratio of the chain length to the depth of the water. According to ENS Andvick, when a vessel drops anchor, the length of the shot cannot be the exact distance between the vessel and the seafloor.  An amount of “extra” chain must be released so that some of it sits on the seafloor, producing a gentle curve up to the vessel.  This curve is called a catenary. The extra chain allows the ship move with the wind and/or waves and provides additional holding power.  If either wind or current becomes too strong for the anchor, it will drag along the seafloor.  If the ship has too little scope it will pull up on the anchor instead of pulling sideways along the sea floor. The anchor chain lies on the bottom and when the ship pulls on the anchor it must lift the heavy chain off the bottom.  If there is enough chain that the ship does not lift all the chain off the sea floor, it will lower the effective pull angle on the anchor. By increasing the scope of chain that is out, the crew is increasing the amount of weight the ship must lift off the sea floor before pulling up on the anchor.

Personal Log 

I have to say that today was kind of an emotional one for me—because I did not go out on the launch. In a way, I feel like I let my team down.  The others who went surveying on RA-4 had to do it without me.  Even though my work as a Teacher at Sea may not be as significant as that of the crew members or hydrographers, I’m feeling like I am a part of the team more and more each day. That is in contrast to being an observer (which I still do plenty of!).  As I kept busy throughout the day on the ship, I thought about RA-4 and what they were doing, what the conditions were like, if they liked what was in the lunch cooler today? I also realize and appreciate, however, that safety is the most important practice here on Rainier and when you don’t feel safe, you should never proceed.

Did You Know? 
The crew on Rainier is organized into six separate departments:  Wardroom (Officers), Deck, Electronics, Engineering, Steward and Survey.  There are photographs of each person on board along with their name and title posted for all to see.  They are organized by department as well as a “Visitors” section.  There are several other visitors on board besides me and Dan Steelquist (the other Teacher at Sea) including hydrography students and officers from the Colombian and Chilean Navies.

Science and Technology Log 

Launches 1010 and 1018 were deployed on both days.  They were tasked with offshore and nearshore bathymetry in separate areas about 10-15 miles away.  These launch ops, as I mentioned earlier, are in areas too close to shore for the Fairweather to operate. In the afternoon the “fast rescue” boat (another of the Fairweather’s inflatables) was deployed to train another crew member as a coxswain, and the Ambar was again deployed to check another tide station.

It’s important to realize that every position on board the Fairweather requires both experience and training. For example, to become a QMED (Qualified Member of the Engine Department) takes a minimum of two years training and apprenticeship.  The chefs (as I mentioned earlier) are all graduates of culinary programs.  As I continue to chat with crew and survey members, their educations and backgrounds are remarkably diverse, yet there is a common thread among them: they are immensely proud of the Fairweather and the work that’s done aboard her.

The history of coastal surveying dates back in the United States to the founding fathers.  In 1807 Thomas Jefferson called for a survey of all the coastal waters of the United States.  By the mid1800’s United States Coast and Geodetic Survey personnel were surveying waters on both coasts of the United States. An interesting – though tragic – footnote here is that in 1849 during the height of the California Gold Rush, there was a mutiny on board the Ewing, a hydrographic survey ship.  Five mutineers were convicted and sentenced to hang.  Ultimately three sentences were commuted to hard labor and the other two were hanged from the yardarms of two ships, the Ewing and the Savannah, in San Francisco Bay on October 23, about 40 days after the mutiny.

Coast surveyors did a great deal of work during the Civil War in both land campaigns and blockades of southern ports. They became particular targets of snipers.  In both World War I and World War II, Coast and geodetic Surveyors were transferred to the Army, Navy and Marines for their expertise in navigation, engineering, hydrography and vessel operations.

In 1970 under President Nixon, several fisheries agencies and the Environmental Science Services Administration (ESSA) were combined into one agency under the domain of the Department of Commerce.  This was the “birth” of NOAA – the National Oceanic and Atmospheric Administration.  There are seven major branches within NOAA: the branch that oversees the Fairweather is the National Ocean Service and more specifically, the Office of Coast Survey.  I’ve had folks ask me why Hydrographic research should be under the Department of Commerce and not the Coast Guard or Navy. Consider the following data.  The marine transportation system in the United States has

  1. 95,000 miles of U.S. coastline 
  2. 25,000 miles of navigable channels 
  3. 326 public/private ports 
  4. 3700 marine terminals 
  5. Supports 13M jobs, 
  6. 78M recreational boaters 
  7. 110,000 commercial/recreational fishing vessels 
  8. 95% of U.S. foreign trade in/out by ship.

All totaled, the marine industry represents a contribution of almost $750 BILLION a year to America’s Gross Domestic Product.  That’s 3/4 of a TRILLION dollars. Sounds like Commerce to me! All top level organizations have a means for their people to understand their place as a part of a greater whole. This is clearly described below.

Vision 
Customers have accurate and timely information to navigate and manage U.S. coastal waters.

Mission 
Acquire, integrate, and manage the Nation’s marine information for nautical charting and coastal applications.

Slogan

Personal Log 

I was not on the boats that went out today and due to the fog and the fact that Fairweather’s size will not be needed until we move further south tomorrow.  It gave me some time to reflect on the type of people with whom I am working.  Tami Beduhn, a survey technician, gave me several powerpoint files related to the mission of the Fairweather from which I gleaned the brief history above.

I had a couple of chats today with personnel on board – one of the chefs, a member of the engine department, Tami and a few others.  The overarching impression that is inescapable is that they are proud of what they do and of how well they do it. After dinner this evening there was a 1/2 hour presentation on the intricacies of the data acquisition programs and how our field work affects the software and vice versa.  It was an open professional forum where questions were dealt with in a collegial fashion.  Schools and educators are moving in the direction of professional learning communities (PLC’s) as a means of improving.  On the Fairweather, a professional learning community isn’t a technique.  It’s a way of life.

Questions for You to Investigate 

  1. Does your school have a stated Mission, Vision and Slogan?
  2. How, as a student, could the idea of working together help you be more successful?
  3. Are you a member of a professional learning community where you work?

Ian Colvert, Martha Herzog, and Matt Abraham are my team for today.  We are working in area that has not had any survey lines run yet. We are the first to explore what lies beneath the water!  The survey that we are conducting today will involve running long lines instead of filling in polygons. The long survey lines provide the survey techs with an idea of what to expect for the area and assist them in planning the polygons that will be covered later.  If rocks are known to exist, these first lines go near to them in an effort to determine bottom features at a safe distance.

The Reson froze twice today for some reason, but was able to start right up again.  This issue was brought up at the daily meeting and it appears to have happened on another launch as well.  (The ship is in frequent contact with the company and will have a solution to this problem quickly.)

The instrument is then lowered to the bottom and retrieved using the winch.

I was able to pilot the launch for a complete line today.  I am proud to say that after learning to orient the boat using the information on the screen, I did a good job.  After the first cast of the CTD, Martha and Ian let me go ahead and perform the next two casts of the day.  The data collected from the casts was good, so we did not have to perform any recasts.

Ian made a couple of movies of the Reson data today that I will be able to take back to my classroom. I went ahead and took pictures of the side scan display to show students. I am going to go ahead and use my digital camera to make a movie of the side scan screen.  Hopefully, it will work.

In the area that we surveyed today, there is a huge, interestingly shaped rock. As we passed by the rock, we noticed light colored areas along the rock. These light colored areas were seals. It was an impressive sight!

The launch leaves the ship every day to go to spots within the survey area to collect data regarding the bottom for depth, possible anchorage sites and potential navigational hazards.  Our boat was responsible for covering the long area referred to as the fairway, which is necessary in this uncharted area so that the launches can transit to and from the working areas safely, and move on to another area upon completion.

The chart of the area is “painted” with color depicting the depth of the area based upon the return form the sonar.  The goal is to “paint” your assigned area.  The numbers in the lower right of the screen indicate the depth in meters.

The inside of the cabin of the launch reminds me of Star Wars. There are pieces of electronic equipment everywhere!  One of the survey team members sits in the command center to monitor and control the Reson collection and additional software that displays a 3-D image of the sea floor surface. As the coxswain pilots the boat over the surface of the water, low frequency sonar is emitted from the transducers.  The sonar hits the sea floor and is then bounced back to a receiver on the underside of the boat.  The pings are recorded by the equipment and stored in the computer. 

The CTD is attached to a cable operated by a winch.  The CTD acclimates to the water surface temperature before being lowered steadily to the bottom.  The equipment is raised to the surface using the winch and then brought aboard.  The CTD is connected to the computer for data retrieval.

There are factors that affect the accuracy and quality of the information.  Boat speed, conductivity of the water, pitch and roll, yaw, and tides must be accounted for in order obtain usable data. There is equipment on board that collects the pitch, roll, yaw, and geographic position information to correct merge with the data to make corrections.  The CTD apparatus is placed into the water while the boat is stopped. The cast of the CTD will collect salinity, temperature, and pressure information at depths from the surface to the bottom. This information is also sent to the computer to provide a more accurate reading of the sonar data received by the Reson system.  Casts of the CTD must be made a minimum of every four hours to account for any changes between points in the survey area.

Shawn, Todd, and Dennis were on my launch today. Once the equipment was powered up and the software programs selected, I was able to sit at command center and control collection and storage of data. The raw data is merged with the corrective information and submitted to Caris, another software program that also creates models of the findings. We were using a laptop to merge the data and begin field processing of the data. I was able to assist with this process too.

This morning was a great day to see whales!! We spotted 5 blows!  We were then able to see the whales breach the surface at a distance.  Three of the whales moved closer to us. There were two adults and a juvenile. The juvenile was very playful and kept poking his head above the surface.  The two adults came closer to the launch and we were able to get some great shots of their bodies!! On the way back to the ship, we saw four more blows. Total sightings of whales: 9 Puffins as always are out there. They are very strange, somewhat silly birds….

This morning everyone was abuzz with excitement because today we were to send out the launches and begin to survey the area in the Pavlof Islands that has not yet been charted! The data that we will be collecting during this survey, such as depths and hazards to navigation, will eventually end up on nautical charts.

Here I am driving the launch.  It is essential to hold a steady course while collecting data for the surveys and tests.
Here I am driving the launch. It is essential to hold a steady course while collecting data for the surveys and tests.

Deploying the launches is a fascinating thing to watch. The davits on our ship rely upon gravity, (Newton’s Laws in action…).  The boats are attached with cables and the weight of the launch is used to lower it to the water. As the cable is slowly released, deckhands man lines to assist in guiding the launches slowly toward the water. The crew and their gear are loaded from one of the lower decks and then the launch is lowered the rest of the way to the cold Alaskan water.  Once the launch is in the water, the cables are released from the launch.

The launch that I went out on was running patch tests and collecting Reson data.  The patch tests are necessary to calibrate the multibeam sonar and measure any physical offsets that may induce errors into the acquired data. In order to accomplish this test, we collected data with the sonar by running lines over an area that was surveyed last year.  The sonar that is used to collect information about the depth and underwater objects can be either high or low frequency.  It was important for our boat to test both frequencies.  The frequency used depends upon factors such as the depth of the water.

Personal Log 

Having been on board ship for two days already, I am getting the feel for where everything is located and how meals work.  Now, I have also been introduced to the routine of launching and conducting surveys. Our coxswain allowed me to pilot the boat for one of the runs during our testing. My time on boats at home and on sailing excursions is paying off.

When I visited the bridge to write down the weather information, the officer on bridge watch, Ensign Andvick, was preparing to collect the hourly weather information.  I assisted in the collection of the required data and was excited to be able to learn where the weather instruments are located on the bridge.  I enjoy data collection, so I will time my visits to coincide with the hourly check of the weather, which becomes a part of the ship’s log.  While on the bridge, I also learned that there is some difficulty communicating by radio from the ship to launches in this area. The islands in this area are very high and mountainous, but in similar areas this difficulty has not been noticed. One possibility for the communications issue is that the mountains here have a higher concentration of iron that interferes with the signal.  (Sounds like an idea for a science fair project….). The launches have other methods to communicate with the ship and other launches such as satellite phones.

I had the opportunity to spend time in the plot room with fellow teacher at sea, Mary Patterson while the night processors were working on the data collected during the day.  We continue to meet and work with interesting and fabulous people.

The seals watched us but did not seem to react as we got closer to the area to survey it. The waves were not large but there was lots happening here so the crew and I were very mindful of not only the animals around us but also the rocks that we could see and we were constantly on the lookout for those we could not see.

I wondered how the survey technicians know they are in the right place and they continue to be in the right place while the data is collected.  The short answer is satellites or GPS.  While this was explained to me, here is the official info regarding known location, as explained by NOAA’s Earth Systems Research Laboratory:

“Global Positioning System. GPS was developed by the U.S. Department of Defense to tell us basically three things: where we are, how to get where we want to be, and what time it is right now. This is commonly referred to as “PNT” which stands for positioning, navigation, and timing. GPS is a “dual-use” system in that it has both military and civilian applications. To facilitate the development of civilian applications, the U.S. Government makes the radio signals broadcast by the GPS satellites available to every user free of fees. As a result of this policy, a multi-billion dollar industry has developed to exploit the benefits of GPS for civilian applications. For example, a commercial GPS navigation system in your car tells you where you are on an electronic map that is constantly updated as you move. Computer software in the navigation system tells you the best route to take to get to your destination. Wireless communications between your navigation system and a traffic management system tell you the best route to take to avoid delays or hazards.”

To find out more about the GPS please go to the following link where I found the above paragraph: http://www.esrl.noaa.gov/news/2007/gps/ 

The launches can only collect data when there are a minimum of five satellites receiving and transmitting in orbit above the area that is being surveyed.  The use of five satellites lessens the chance that the information may be skewed by a distortion from one of the satellites.

The survey launch collects data from the sonar device that is located in the bottom of the ship; the computers assemble the feedback on board the launch and continually retransmit that data via satellite back to the RAINIER and it is processed during the evening hours.  The work runs right through the night, with technicians working to ensure the sonic images are transferred into a coherent chart.

I finally had a chance to pilot the launch and of course it looked far easier to do than when I tried it myself.  It seemed like a simple task, to keep the nose, or bow, of the boat on the specific course and while I understood it well enough my attempts were often less than perfect.  The sea was clam with negligible wave height.  The wind was perceivable but not a large influence.  The current was strong but steady and predictable.  The route was clearly indicated on the screen in front of me and yet I could not hold the course steady enough (at least not well enough to collect valid data).  Perhaps I was being too hard on myself: most annoying was the bow of the boat would head in the direction that I wanted it to but the stern of the boat (reacting to the force of the currents) dragged in a way that caused me to simultaneously both over and under compensate for the action.  That coupled with the fact that I had no island or land point of reference made this experience a challenge.  With the help of Mr. Foye, I was given some expert coaching that allowed me to get into a zone. I was in a pattern of both over and under steering and each correction brought me further away from where I wished to be.  I learned that you develop a feel for this sort of thing and while I tried my best, I knew it would take many days of practice before I developed competency navigating this boat.

As the launch approaches the RAINIER, the person near the bow of the launch has a line ready to throw to the crew on board the ship (same in the stern).  The crew on the larger ship needs to hold the launch so it doesn’t bang into the RAINIER.  RAINIER then lowers two cables to attach to the launch (one on the bow and one on the stern).  The cables are hooked onto large shackles and when all is secured the signal is given to the operator to hoist up the launch.  There is only one person signaling to the operator on the ship.  If there is ever a problem, naturally anyone can alert the crew of the problem but there is always only one person signaling to ensure safety of all.

Most days start at 6:30 am with breakfast served promptly at 7:00.  We then get our protective gear on for our days work on the smaller boats.  The gear consist of what is called a “float coat” which is basically a brightly orange colored jacket designed to keep the wearer afloat and warm in the water should they accidentally fall in.  We also wear hard hats and when hoisting the launch, a life jacket, and ear protection (the diesel engines are very loud when underway).  The boats are located on top of the ship and they are lowered into the water using a series of hoists or cranes depending on the boat and where they are located.

At 8:00 am there is a morning meeting on the fantail of the ship (this is a large area on the back of the vessel).  The meeting involves most of the senior officers as well as the crew that will be directly involved in the day’s operation.  The commanding officer speaks first, he will give everyone data regarding the weather and his best guess as what to expect out on the water he then turns the meeting over to another officer who will detail the plans that he has worked on more fully with the rest of the crew.  Lastly the chief engineer will recount the basics of what boat will launch first and reiterate the constant vigilance regarding safety.

I feel very comfortable on the water and extremely safe with this crew.  This is likely because of the constant checking and rechecking of systems and personnel that continually occurs.  The entire crew is mindful that the safety of one depends upon the persistent and sometimes annoyingly extreme attention to detail.  Accidents most often happen when people get too lax or over confident, are tired or in a rush.  Accidents even happen when none of the situations are present which is why the constant mindfulness is so important.

This is a truly collaborative effort.  If one person in the lineup fails to do their job the mission risks failure: someone else has to step in and do the job of the person missing as well as their own.    Deck hands ensure that the boat is fueled and has the necessary equipment on board and is in working order.  Engineers check the engines and the electrical equipment and the kitchen staff prepare the lunches and snacks to take on board.  When the launches are out they are usually deployed for the whole day.  Everything must be ready in the launch for the entire day otherwise the mission risks failure.

Our job on most days is to get on the launch and survey the area that the larger ship could not safely operate in.   The larger ship the RAINIER takes up far too much draft (the water the hull displaces when the boat is underway).  This does not mean that the RAINIER is simply sitting idly by while the launches do the work.  The ship also runs back and forth patterns in the area and it too collects data.  The larger and smaller launches are always on the lookout for any hazards to navigation, other boats or any marine life-like a whale and make sure that collisions do not occur.

Once we arrive at the survey area we need to prepare the CTD cast.  CTD is a device that measures the conductivity, temperature, depth, and salinity of the water about to be surveyed.  This establishes a baseline for the work in the area.  If a survey is going longer than four hours a new baseline must be established.  This test establishes a sound profile that shows exactly how the fast the sonar beams travel in the water under the specific conditions at the time.  This information is critical to maintain accurate and credible data.  The procedure is simple, first, the CTD is attached to a rope turned on and warmed up, next the device is lowered in the water and data is collected.  It is then lowered to the bottom of the sea and more data is collected.  Once the CTD is brought back from the ocean, the information is then uploaded to a computer on board and a new baseline is established.  This information is then embedded into the sonar data collected for the day’s survey.  All information collected is held against this baseline to ensure the delivery of clean, accurate information for the new charts.

The best part of this trip is that I traveled with another teacher who teaches Science in Oregon.  TAS Redlinger is a wonderful lady who shared with me all of the photos she took while she was out too.  Often we would spend time sharing what we had done the during the day and what was in store the following day.

This morning the ship navigating in water that is very tricky, we were in a very narrow area and the crew had to make sure that not only we got through safely and other vessels did not run into us.  Because the fog was so thick, horns, bells and radar are all in use.  The technology is not enough one watch at the bow of the ship used to ensure we hit nothing and nothing hit us.   There are also folks in the bridge monitoring the situation.

The watch stands at the bow of the boat and if he looks for anything amiss he will notify the bridge via a low tech device (a tube with a lid on it is connected to the bridge and in the area he is standing) he lifts up the tube and can speak directly to the bridge.  The bridge is the command center where many of the officers and most of the navigation and communication are located.  This is where the ship is steered and managed.

I am in awe the way the entire crew goes about their daily business.  Back East, we go off to work our jobs for an eight hour day and then return home afterward. The men and women of the RAINIER don’t get this luxury.  They live aboard this ship and have to work at building and maintaining the community. Everyone is responsible for everyone else.

There is work that must be preformed twenty four hours a day seven days a week.  If there is a fire onboard help will be called but it may take hours or days for help to arrive.  Emergencies must be taken care of by the people on board the ship.  Safety is a major concern, and to that end the officers and crew work together to make sure that everyone onboard understand their job in the event of an emergency.  Training is constant here.  There is a good mixture between folks that have less than one year experience aboard ship and others that have almost thirty.  The more experienced people on board teach the less experienced how to do things safely and efficiently.

Gender bias does not appear to exist in the positions that individuals hold.  Women work both as deck hands right up to the second in command of the entire ship.  It is striking that both women and men hold positions in both the officer corps as well as throughout the operations of the vessel.  Much of the equipment that is aboard this ship weighs several tons.  When the ship is underway, (in operation) there are additional considerations that make this environment much different from being on land.  The ocean movement causes the ship to react and each reaction has a term.  The ship moves in many ways, the three main ones are pitch, roll and heave.  Pitch is when the ship moves from Forward to Aft (front to back).  Roll is when the ship moves from port to starboard (left to right or vice versa).  Heave is when the ship moves in an up and down motion.  This does not even begin to take into account the effects of tide, wind, drift or other ships or obstacles that are at play when underway.

Moving a launch requires careful communication as well as good rigging skills.  A constant vigilance is also mandatory.

There are hoist and davits that swing equipment overhead that could easily crush or kill a person or hopelessly destroy valuable equipment. Safety precautions are rigorously followed and training is in an ongoing evolution.   Simply put, if the entire crew did not keep a constant vigilance not only for themselves but for their shipmates and guests, disaster could strike at any time.  There is a pervasive attitude aboard the RAINIER involves everyone watching out for each other.

Personal log,

Women play an important role on board the ship.  They fill all sorts of positions that may not be considered traditional by some standards.  Many of the officers on board are women and even lots of the able bodied seamen are women.

On the bow of the launch, an able bodied seaman must first throw the line to a tender on board and then get hold of a lowering hook to attach the hook to the launch to hoist back on board the ship.  This all takes place in Open Ocean while the ship and launch are underway and the boats are reacting to the elements.

Personal Log 

The commute from Hartford, Connecticut to Juneau, Alaska was very long. I began my journey by saying good bye to my wife and three young daughters; they understood for the next three weeks, I was starting an awesome adventure.  The plane took off from Bradley international airport at 12:10 p.m. and we headed to Detroit Michigan.  Laid over in Detroit for an hour and then transferred to another flight to Seattle, Washington. In Seattle I transferred to an entirely different airline to arrive in Ketchikan, Alaska from there we flew to Juneau, the time in Alaska was 1:35 am very dark yet comfortably warm. My travel plans were quite clear but a bit complicated.  I boarded a flight to Detroit, then to Seattle, next to Ketchikan, Alaska and finally Juneau, Alaska.

The ship is equipped with two General Motors EMD diesel engines that transmit 1,200 horse power each. These engines are forty years old and they still run reliably and are kept remarkably clean

The first thing I learned was that while the tickets indicate the gate to arrive in, and where to board the next plane, these are only best guesses, often changes happen at airports so flexibility and vigilance is critical. Airports handle all sorts of air traffic with myriad of travel conditions.  If one flight is delayed it impacts others and causes shifts in the gates.  The gate often changes so it is wise to check the ticket (which was printed hours earlier) to ensure it still has valid information on it. Changes happen and it is better to be safe by checking (at the individual airport gate) rather than wait in the wrong area and miss a flight.

In Seattle, I discovered the information on the ticket was inaccurate I had to move via subway to the new gate.  The plane then was delayed due to weather conditions in Ketchikan; we boarded an hour and a half later than scheduled.  We touched down in Juneau at 12:05am but I was still operating on east coast time (it is four hours later on the east coast). Obviously I was very tired. When we arrived many of the passengers were surprised to discover that their luggage had not been placed on the plane.  I was among those without luggage.  Should this happen to you, I recommend the following.

First, do not panic, while I was getting upset, I had to keep my emotions in check.  There is much the clerk can do to help me but I first must provide the details, if I expressed my frustration and dissatisfaction with them (I noticed other passengers doing this) it would only make matters worse.  They collected my information and I headed to the motel.  I was trying to problem solve my situation by imaging different scenarios in the event that my luggage was not found.  One of my major concerns was could I find size fourteen boots in Juneau, Alaska on a Sunday afternoon.

Chris Zacharias, my bunkmate, gave me a tour of the engine room.

Chris works maintaining the equipment on the smaller launches as well as working primarily in the engine room but he has responsibilities located all around the ship.  Interestingly enough this is normal procedure for the entire crew.  While on land we have individual who specialize in only one thing.  Out on the open ocean it is not uncommon for the folks to do many different tasks; in fact everyone has to develop an intuition and recognition of the inter-dependence of the entire community.  Chris was kind enough to show me the engine room.  He did so with an obvious pride, he has pride in his work and he demonstrates this pride with his enthusiasm for his work aboard the RAINIER.

The first thing that struck me was how clean the engine room was. Everything was stowed away and neat.  The apparent care and planning as well as tremendous attention to detail was evident every where I looked. All the surfaces are painted and clearly marked. Even the piping has tags on them.  All the valves are labeled for easy recognition.  There is no visible grease or grime anywhere. Click the following link to get more info about the engine room.

Science and Technology Log 

One very important aspect of working on the RAINIER is communication.  To get the job done everyone needs to communicate clearly and effectively.  This extends into every part of working and living on the ship. Communication is by voice, flags, and hand signals. People talk face-to-face, by radio, bells, Public Address system, posted notices, and by email.  For every form of communication there are certain “right” ways to participate.

Voice communication is much more formal on the bridge where orders and responses have to do with running the ship. When a command is given by the Conning Officer or the Officer of the Deck, it is repeated by the person to whom it was given followed by the response, “aye.” That person then repeats the command again to indicate it has been accomplished, and the person who gave the order acknowledges that by saying “Very well.” Since there are often at least two people carrying out different commands on the bridge at the same time, it is very important that this procedure is followed so the person in charge knows that orders have been heard and followed.

When members of the Deck, Engine, Survey, or Galley crews address the NOAA Corps officers and department heads on the ship, they call them by rank and name, or just by rank. The Commanding Officer is always addressed as “Captain” or “CO,” and the Executive Officer is always addressed as “XO” or by rank and last name.  Department heads should be addressed as “Chief.”  This formality helps avoid confusion in following the chain of command, the organization that keeps the ship running smoothly.

Flags are used as signals to people off the ship about what is going on.  At anchor a Union Jack is flown on the bow from the jack staff.  A black “anchor ball” is raised on the forward bow stay (line), and the Stars and Stripes flies from the aft mast.  The ship’s commission pennant always flies from the forward mast.  When the ship is refueling, a red flag is flown from the forward mast on the port side.  When the ship is under way, a smaller-sized Stars and Stripes and the NOAA service flag are flown.  Our nation’s flag is always flown from the aft mast and the service flag is on the forward mast.  Other special flags are flown when certain VIPs come on board and are taken down when they leave.

The ship’s radios are used for important voice communication.  The protocol is for the speaker to give the call sign (code) for the person to whom they are speaking, followed by their own identifying call sign. Communication via radio is very direct, in as clear language as possible, and never uses the civilian law-enforcement 10-code language.  To indicate that a person has received and will comply with a message, the response is “Roger.” These radio communications are very important on the RAINIER during the day when survey boats are working away from the ship on hydrographic surveying.  It is important for the boats and the ship to stay in touch for both safety and efficiency.

When survey boats are being lowered or raised to the ship or when the anchor is being raised crew members reinforce voice communication with specific hand signals as well. When launches (survey boats) are being raised and lowered a closed fist means “Stop!”  The index finger on a closed hand pointing up or down shows the direction for winches to move the boat. Different signals are used for operating the cranes on the bow and stern of the ship, using the thumbs, and different motions of the hands with either the index finger, or the first two fingers extended. It is important for all crewmembers to understand the signals and watch for them because machinery is sometimes noisy, making it hard to clearly hear voice commands.

It is very important for everyone on the ship to learn the bell signals that are used.  They are to alert the officers and crew to emergencies and they demand immediate responses.  Upon coming aboard the ship, each person is given a safety briefing and assigned emergency muster stations for response during drills and emergencies.  When the alarm bell rings (or the ship’s whistle sounds) 7 short and 1 long, followed by the announcement “Prepare to Abandon Ship” on the PA system, all personnel report immediately to their Abandon Ship stations wearing a jacket, long pants and a hat, and carrying their survival suit and whatever specific supplies have been put on the personal assignment.  At least once each cruise there is a drill when everyone dons their survival suits and checks whistles, zippers and lights to be sure they are working.

The Fire/Emergency signal is a continuous sounding of the ship’s bell (or whistle) for at least 10 seconds, followed by an announcement about the specific emergency.  All personnel must immediately report to their muster stations wearing their floatation (Mustang) coats.  The person in charge at a muster station accounts for each person and reports that all are or are not accounted for.  The radio is used to dispatch particular crews to their assigned Fire/Emergency responsibilities.  Dismissal is by 3 short whistle blasts or bells followed by the announcement “Secure from fire/emergency.”

Three long bells or whistle blasts followed by the announcement “Man Overboard, port/starboard side!” is the signal for all personnel to report to Man Overboard muster stations immediately.  This enables roll to be taken to identify who is missing and emergency recover procedures to be initiated. All of these signals, whether for drills or actual emergencies, are taken very seriously. Everyone practices the drills at least once per week so that the ship’s personnel can respond immediately with the least possible confusion.

The other two forms of communication used on the ship are posted notices and email messages.  Each person on the ship has an email account with a NOAA address.  The CO regularly posts bulletins of general interest such as the weather forecast, general orders, or information from fleet headquarters on policy and procedures.  Officers and crew use the email for interpersonal communications and it is also available for limited personal use. There are notices posted regularly on the ship’s bulletin boards that all personnel are responsible for reading. These include the Plan of the Day (POD: work schedule and assignments) and more general schedules such as hours the store and the dispensary are open. The menus for meals are posted in the mess and the movies being shown are listed each evening.

Each of these forms of communication is very important to the people aboard the RAINIER. It is impressive to see how well they work.  Nobody mumbles or takes shortcuts. I have not heard anyone answer “uhn-hunh” or “uhnt-unh” nor have I seen anyone respond to another person with headshakes or shrugs.

Personal Log 

Today the weather was windy and wet as a low pressure system passed over us.  The storm actually started last night and got pretty rough.  We were anchored in a sheltered bay so we didn’t get the worst of the winds.  Even so, there were gusts up to almost 60 knots. I woke up several times hearing the anchor chain rub loudly against the hull as the wind spun the ship around. The movement of the ship was pleasant to sleep to.

This seemed like a great morning to catch a nap as I had been up really late last night cleaning fish. I had just settled in to sleep when the Fire/Emergency bell sounded.  (At first I thought recess was over!) I jumped off my bunk, grabbed my coat and hat, and was half-way outside when they announced we should disregard the bell, there was no emergency.  About an hour later, the bell rang again and it was an F/E drill for real so I grabbed my Mustang coat and sped to my muster station on the fantail.  We were outside in the very fresh air for about 20 minutes while they accounted for all personnel and completed the steps of drill.

Just after lunch there was an Abandon Ship drill and we were told to report to our “indoor donning” areas to put on survival suits and check that all parts worked properly.  I struggled into my “Gumby” suit, stretched on my fleece hat, blew on my signaling whistle and flipped my strobe light on and off.  Everything worked fine.  Those suits are very warm when you are inside and I was really happy to take it off and repack it into its carrying bag.

Science and Technology Log

Since I’ve been aboard the RAINIER, I’ve wondered how the ship has been able to go for so long on fuel and water given that we are at sea for 19 days.  I also wanted to know what happens to all of the sewage we’ve been creating. I spoke with 1st Assistant Engineer Glen Quintino and General Vessel Assistants (GVA) Chris Zacharias and Milton Ellison from the Engineering Department to find out.  There are 2 engines on the ship, one on the starboard side and one on the port side. The engines run on diesel fuel.  There are 26 diesel fuel tanks on the ship with a total capacity of approximately 114,000 gallons.  Since there’s a lot of added weight from the fuel, as it’s used, the fuel needs to be moved around from tank to tank to keep the weight evenly distributed. Although the RAINIER does not use all of the fuel on a leg as long as this one, they do re-fuel when they get into port.

Fresh water is made on board the ship.  There are two water tanks, each with a capacity of about 8000 gallons. Salt water is pumped into the ship from below and heated to a very high temperature in the evaporator in order to evaporate the water and leave the solid salt behind. Once the salt is removed and disposed of, the desalinated water is then further purified by the addition of bromine and used as fresh water on the ship for drinking, cooking, and bathing.  I’ve been drinking it since I arrived and it’s great!  The toilets do not use freshwater; they use salt water to flush everything out.  Any of the sewage waste created aboard the ship is also treated. The sewage is literally electrocuted using a Marine Sanitation Device (MSD).  Between the salt in the sewage water and the electricity, sodium hypochloride (essentially chlorine) is created.  The treated sewage is placed in a holding tank and then pumped into the sea.

Who’s Who On the RAINIER? 

In the Engineering Department, the 1st Assistant Engineer is Glen Quintino.  Currently a resident of Seattle, WA, Glen is originally from California.  He has been with NOAA for six years, first working on the NOAA Ship McARTHUR before joining the RAINIER.  Glen went to a trade school in Denmark to study being a machinist.  He then worked for a company that made non-ferrous propellers, oil filters, and ship windows before joining NOAA in 1998. Glen was recently married in February 2006.

Engineering GVA Chris Zacharias and GVA Milton Ellison were both in the Navy in their former lives, each for 10 years. Chris is from Kansas where he still resides with his wife. Milton is originally from Tennessee, however, his residence is currently Michigan where his wife’s family is from.  Milton has been with NOAA and on the RAINIER for 4 months.  His prior experience was working in Engineering on commercial vessels in the Great Lakes area.

Many of the crewmembers, like Glen, Chris, and Milton, are married or have significant others at home.  Almost everyone I’ve spoken to agrees that one of the most challenging parts of their job is to be away from their loved ones for extended periods of time, especially the ones on board who are newlyweds.

We continue our journey back to Seward, AK traveling at approximately 13 knots.  It feels like we’re speeding compared to the speeds we were going for the past few weeks.  Although cloudy, the water is still amazingly calm which I am very grateful for.  It seems we may have left the blue skies and sunshine back in the Shumagin Islands since the extended forecast for the Seward area calls for rain or showers.  We’re currently scheduled to actually arrive early in Seward if the weather and mechanics of the ship cooperate. I’m looking forward to being back on land and checking out Seward before I depart for Anchorage Friday evening and a short excursion up to Denali National Park before flying home next Monday.  Keeping my fingers crossed and eyes open for more animals!

Winding Down 

I’ve been keeping a running list of the Alaskan wildlife that I’m seeing along this excursion.  Some of the animals I’ve mentioned already are the puffins, bald eagles, Orcas, and Dall’s porpoise.  Occasionally while out in a kayak or survey boat or on a beach along the coastline I’ve also spotted harbor seals.  Their adorable little faces will emerge from the beneath the water and bob around, almost appearing at first to be kelp floating in the water.  While kayaking I’ve also seen two hauled out on rocks where they were almost mistaken for pieces of logs washed ashore.  They are very quiet and easily disturbed if you get too close.

Harbor seals (Phoca vitulina) are marine mammals most often associated with coastal waters. They periodically haul out of the water on sand and gravel beaches, reefs, sand bars, and glacial and sea ice to rest, give birth, and nurse their pups. Unlike many marine mammals, harbor seals do not make long annual migrations, however, they do move around considerably in a more localized area. At birth harbor seals weigh about 24 pounds. They gain weight rapidly during a month long suckling period. Average adults weigh 180 pounds.  Until about 5 years of age, there are approximately equal numbers of male and female harbor seals in a population. After that, mortality rates are much higher for the males, therefore female harbor seals becomes much more abundant.  Adapted to life in the sea, they can dive up to 600 feet (183 meters) and remain submerged for 20 minutes!  Some adaptations that allow for oxygen conservation in harbor seal are reduced peripheral circulation, reduced heart rate, and high levels of myoglobin (an oxygen binder). Harbor seals move under water by using their hind flippers for propulsion and their fore flippers as rudders. In Alaska harbor seals commonly eat walleye, pollock, Pacific cod, capelin, eulachon, Pacific herring, salmon, octopus, and squid.

Personal Log 

Today after all of the survey boats return we will begin our journey back to Seward, AK.  This leg of the RAINIER’S travels, as well as mine, are winding down.  All of the surveying is complete until the RAINIER leaves Seward, AK for its next leg early next week. I’ve already taken some meclizine to hopefully ward off any potential seasickness, as we will be underway for about 2 days once we take up the anchor.  It appears that with this end of surveying and the turning back of the ship there has also been a rather symbolic turn in the weather.  It has gone from incredible weather yesterday to a falling barometer, heavily cloudy skies, and a forecast calling for higher winds and waves.   I’m glad I went kayaking the past 2 days!

Moonrise in Porpoise Harbor, Nagai Island, after 11pm!

Science & Technology 

Today has been the absolute best weather we’ve had since we left Kodiak.  The skies were clear, the water was calm, and the temperature was perfect!  This is after having a beautiful moonrise last night.  At 0700 I joined three other crewmembers for a few hours of shoreline surveying in the Porpoise Harbor area.  Shoreline surveys are different from the work we were doing previously. We needed to go out an hour earlier during the low low tide since rocks, ledges, and other shoreline features are more exposed at this time.  The purpose of our survey today was to confirm or disprove the existence of certain shoreline features that could not be verified by the LIDAR, such as the existence of rocks or islets.  Prior to the RAINIER doing their survey work, planes flew over the area using a technology called LIDAR, which stands for LIght Detection and Ranging. The distance to an object or surface is determined by the time delay between the transmission of a laser pulse and the detection of a reflected signal. This information helps in forming a model of the area.  The laser uses shorter wavelengths than radar would, therefore, a higher resolution image is produced.

The survey boat we were using today was equipped with a single-beam sonar system since we were in very shallow water.  The deeper water we were surveying on the other boats used a multi-beam system.  The boat went to designated areas and slowly moved in a series of figure 8s to get readings from the transducer mounted on the hull (bottom).  In addition to the readings being recorded on the computer system, an echosounder created a visual image of the soundings being received, called a “paper trace”.  My job was to operate the echosounder when we were logging data. Once we returned back to the ship, the data needed to be processed, similar to the processing of the data taken from the line surveys to eliminate any “noise”.

While we were out on the survey boat, we saw an immature Bald Eagle (Haliaeetus leucocephalus) perched on a log on the coastline. The distinctive white head and tail of the adult Bald Eagle are not seen for 4-5 years on the immature eagles.  Bald Eagles, which are the symbol of our nation, are the second largest raptor (bird of prey) in the state of Alaska, with a wingspan of up to 7 ••• feet (2.3 m) and weights of 8 to 14 pounds (3.6-6.4 kg).  The Stellar Sea Eagle is the largest. The Bald Eagle is more abundant in Alaska than anywhere else in the United States. Their largest nesting densities occur along the islands of Southeast Alaska.  Bald Eagle nests are usually built close to water.  They will often use and rebuild the same next each year.  The male and female eagle work together to build their nest in early April and two to three eggs are usually laid by late April.  Once the chicks hatch after 35 days of incubation, they stay in the nest for another 75 days to grow and develop. The main diet of Bald Eagles is fish such as herring, flounder, pollock, and salmon as well as waterfowl, small mammals, sea urchins, clams, crabs, and carrion.

Personal Log 

We moved the ship to the other side of Nagai Island again, this time to East Bight.  Each time we anchor, we need to hang out an anchor ball over the bow of the ship as a signal to other ships that we are anchored.  I had the opportunity to be the person to hoist up the anchor ball today. Like other things on the ship, there are certain traditions.  I had to actually wait for the anchor to begin being dropped before I could hoist up the anchor ball.

What amazing scenery surrounds us!  In mid-afternoon I went kayaking again with the acting CO, CDR Julia Neander. We were able to get close to the shoreline and discovered that there were little caves that went under the rocks in front of us.  It was tempting to explore further, but my better judgment restrained me from doing so.   There are such incredible geological formations in these rocks! As we paddled, many puffins circled around us and floated in the water. Not only did we see the horned puffin (Fratercula corniculata) today but there were also tufted puffins (Fratercula cirrhata). One easily recognizable difference in the two birds is the yellow tuft of feathers on each side of the tufted puffins head. Every time I tried to get a photo they’d all fly away!

Today was an absolutely beautiful day here in the Shumagin Islands.  By afternoon the clouds cleared out and the blue skies and sunshine took over. The acting Commanding Officer (CO) Julia Neander invited me to go kayaking with her, which I eagerly said yes to. We paddled along the coastline right into seagull territory.  Although the sounds of the ship’s engines were fading, the screeching seagulls filled our ears.

We also encountered many horned puffins (Fratercula corniculata), which are the cutest and silliest looking birds. They appeared to have some nesting areas on the rocky cliffs which they were trying to distract us from locating since they kept circling above us and flying away from the cliffs.  Puffins typically stay out on the open sea through the winter but come to the land in late spring to breed.  They are better built for swimming than flying which is evident when you see them fly.  Under water their wings are used to propel them while their webbed feet are for maneuvering.  To get airborne, they must run along the water surface before taking off.  From land, they dive off cliffs to gain enough speed for flight, using their feet to help change direction.  Puffins feed in flocks, eating mainly fish and zooplankton.  They will dive straight into the water and continue their motion as they swim to get their next meal.

LT Ben Evans, the acting Executive Officer (XO), invited the other TAS, Jackie Hams, and me to dinner in the Wardroom this evening.  Traditionally, the Wardroom is where the officers eat. Upholding tradition, the officers on the RAINIER have their meals there.  There’s even a seating arrangement, also based on tradition.  I felt honored to be asked to eat with the officers since the rest of the crew eats in the Crew Mess, which is where I’ve had all of my meals as well. After dinner this evening, I joined three of the NOAA divers and AB Leslie Abramson, who was snorkeling, as they did a recreational dive close to the ship. Since I am not a NOAA diver I was only able to stay on the skiff as they went under water. The water temperature was relatively warm at 52 degrees Fahrenheit. The divers all wore dry suits while Leslie wore a rather thick wet suit (7mm).  Everyone wore a hood, booties, and gloves, all as protection from the cold water temperatures.

Who’s Who on the NOAA ship RAINIER? 

What I’ve recently learned and find very interesting is that there are several NOAA scuba divers onboard.  Being a recreational diver, I was curious to learn about the NOAA divers.  To become a NOAA diver, you need to complete the NOAA diver-training program through the NOAA Diving Program (NDP).  Most of the training takes place at the facility in Seattle, Washington, however, in January there is also a class held in Key West, Florida.

Currently, there are six NOAA divers aboard the ship. They are: LT Ben Evans, ENS Sam Greenaway, Seaman Surveyor (SS) Carl VerPlank, SS Corey Muzzey, Senior Survey Technician (SST) Erin Campbell, and Able Seaman (AB) Jonathan Anderson.  Another NOAA diver not on this leg is the 3rd Assistant Engineer Mike Riley. In the fall, ENS Nathan Eldridge, SS Eric Davis, and AB Leslie Abramson are going for their NOAA diver training, which takes place over a three-week period.  SST Campbell and ENS Greenaway will also complete their Dive Master training in the fall.

NOAA divers have various jobs depending upon their locations.  Divers can deploy and retrieve scientific instruments, document fish and marine animal behavior, perform emergency and routine ship repair and maintenance, and investigate submerged objects such as shipwrecks for nautical charting. Aboard the RAINIER, one of the common jobs of the divers is to install tide gauges 10-15 feet below water.

Safety 

We had a Damage Control (DC) training program this morning, run by Chief Boatswain Jim Kruger.  Damage control is another means of keeping the ship and the crew safe. If there was ever a fire, leaking pipe, flooding or any other emergency that puts the integrity of the ship in question, it’s important for the crew to know where the proper equipment is located and how to respond to such emergencies.  More detailed training is done on responding to various emergencies and using the equipment at other times.

I’ve mentioned in other logs how important safety is on the ship and how much it’s emphasized.  Some of the things I’ve identified since I’ve been onboard as part of the ship’s safety are: the wearing of hardhats and float jackets on the deck when deck work is being done, wearing safety glasses when working with paint and chemicals, wearing long pants and long sleeves on the deck, tying long hair back, fire hoses and fire extinguishers located all over the ship, eyewash stations, damage control lockers on various outside decks with equipment for emergencies, closing all hatch doors after you pass through them, storing all gear and equipment properly, as well as frequent safety drills (fire drills, abandon ship, and man overboard).

All of the things done here on the ship are very similar to the types of safety precautions taken at school in the science classroom. Although a different environment, many of the same safety hazards exist.  The Boatswain Group Leader Steve Foye was telling me about some of the chemicals used on the ship.  Some of them were chemicals used in some of the chemistry labs we do!  He said there was no way he’d allow his workers to work without the proper safety attire and these are adults!

Personal Log 

Last night while I was standing on the bridge, I was given the opportunity to steer the ship for a little while which made me the helmsperson.  Another one of those experiences where it looks a heck of a lot easier than it really is.  It takes awhile to get the feel of the ship. I also had a chance to control the engines as we were anchoring. I was better at this task since the ship’s momentum didn’t effect what I was doing.

I’m learning that there’s a special language used aboard a ship. Aside from there being different names for parts of the ship, there’s also a special way to communicate. For example, while I was on the bridge as helmsperson and controlling the engines, I needed to repeat the directions given to me (ex. “all ahead 2, aye”) so the Officer on the Deck (OOD) knew I heard him. Once I completed a command, I needed to repeat the command again. The OOD then lets you know he/she heard you by saying “very well”. Sometimes commands came faster than I was completing them but as long as I was listening and we were communicating all was “very well”.

I was out on another survey boat today from 0800 to 1630.  It was a long day since we were running rather long lines using the hull-mounted (on the bottom of the boat) Elac multi-beam echo sounder system, which is used to obtain full-bottom coverage in depths ranging from 40-400 meters. The other day when I was out the sonar used was called a Reson, which used to obtain full-bottom coverage in depths ranging from 4-150 meters. The lines took about 40 minutes each to do due to their lengths as well as the fact that we couldn’t go above 8 knots. The coxswain today, Ken Keys, allowed me to drive the boat for a while which I thoroughly enjoyed. Ken did a great job teaching me how to stay on the lines and turn from one line to another. I was very happy when I completed one line and made the turn to another one successfully with no help.

At about 2200 I was on the bridge chatting when Lieutenant (LT) Ben Evans opened the door and informed me that there were Orcas off the stern of the ship. Once I retrieved my camera, I joined some other crewmembers for about 20 minutes watching the pod (group) of Orcas swim through the cove which we are anchored in. There were at minimum 15 Orcas, maybe more.  It appeared that the pod was perhaps hunting salmon or some other fish.  Orcas are also known as killer whales, however, they are not really whales.  They are in fact the largest members of the dolphin family (Delphinidae).  They are called killer whales because they attack and consume whales or other large prey, such as sea lions and seals.  They’ve also been known to feed on river otters, squid, and several species of sea birds.  The Orcas we were watching displayed characteristic hunting behavior since they stayed in their pod and a smaller group hung back in shallower waters to possibly chase the fish into the deeper waters where the rest of the pod was. They often feed in this cooperative manner.

Personal Log 

Every job on the ship has so many details to it.  Initially one might think they could do the same job easily.  It has been quite an awakening for me to learn just how much goes in to all of the various jobs on the RAINIER. Everyone has been so patient and excellent at demonstrating and explaining things to me.  Many of them would be excellent classroom teachers.  Ken did a great job today getting me relaxed and comfortable with the task of driving the survey boat on the line.  Thank you Ken! •

Seeing the Orcas this evening was one of those moments where I stood back and just lived in the moment.  It was truly amazing.  Everyone on the ship that was watching was silent as we listened and watched the Orcas swim through the water, blow water out of their blowholes, flap their tails (tail lob), and occasionally jump straight up out of the water (called a spy hop).  Spectacular!

Who’s Who on the NOAA ship RAINIER? 

Since March 2004, Tonya Watson has been working for NOAA aboard the ship RAINIER. She originally began working in Engineering and in September 2005 she joined the Survey Department.  Currently she is a Hydrographic Junior Survey Technician (HJST). Recently she and her husband relocated their home to Phoenix, AZ, however, Tonya has been on the ship working since her move.

In her previous life, Tonya spent 4.5 years in the Navy working with passive sonar.  She has an A.A. degree from Shasta College in California and has studied biological oceanography at Chico State in California and Auburn University in Alabama.  Her Navy experience definitely helps her with the hydrographic survey work she is now doing with NOAA.

Tonya enjoys her work very much.  She really likes to go on the survey launches, seeing wildlife, being out on the ocean, and traveling to new places.  In her down time she likes to read, watch movies, listen to music, water ski, and bike ride.  Occasionally, Tonya says, the logistics of ship life and following strict schedules can be challenging.

There are some very important skills needed for the type of work Tonya does.  In her opinion, reading and writing skills are imperative.  Individuals need to be able to communicate effectively and fill out various forms.  In addition, keyboarding/computer skills are also needed. Individuals should be able to display self-discipline, be dependable, and have good people skills.  On the ship, many people rely on each other to carry out a task successfully.

Science and Technology Log 

Today I went out on my first survey boat. After finishing up some survey work in the Porpoise Harbor area, we were supposed to join another boat on the other side of the island at a place called East Cape Wedge to run some lines.  Before we could get there, the other boat was calling back to the ship regarding the weather conditions.  They had winds of about 20-25 knots with swells of 4-5 feet in the water…not very favorable for driving a survey boat in. They decided to err on the side of caution and headed back to the ship before the conditions worsened. It’s amazing how we can be in such close proximity to one another but separated by some land and have different weather conditions. The boat I was on was completing some of the survey lines called holidays. A holiday can occur for many reasons when lines are run. Basically there was a gap in the data that was acquired by another boat, therefore, those sections of lines needed to be revisited to acquire the data in order to get a complete model of the sea floor.

A CTD, which gets lowered into the water prior to beginning surveys to get a reading on the speed of sound through the water.
A CTD, which gets lowered into the water prior to beginning surveys to get a reading on the speed of sound through the water.

Before we could begin collecting data today, we needed to do a CTD cast. This was done on the ship earlier in the cruise when we were doing surveying from the ship as well. The cast data supplies the given speed of sound through water in a particular location. This information gets input into the program used to process the sonar data so that it can be adjusted for the speed of sound of the water being surveyed. The multi-beam sonar, which is mounted on the underside of the boat, has what is called a transducer on it.  The transducer converts electrical energy into sound and emits the sound waves through the water. These sound waves will eventually hit an object (ie: a rock or the sea floor) and reflect back up to be recovered by the transducer. The transducer will measure the angle at which the sound returned, the time it took for the sound to be received, and the intensity of the return. Each transmission received back appears as a dot on the computer monitor.  Where a solid object likely exists the dots are clustered together and can give a visual model of what the sounds waves hit. Like in all science, there are possibilities for biases in the data collected.  In this case, there are several reasons for such biases.  First, not all of the sound waves are reflected perfectly. Some of the sound waves are absorbed by the surfaces of objects.  Second, sound waves may reflect at an angle that the transducer cannot pick up.  Third, some sound waves may ricochet off of a few surfaces before making it back to the transducer, therefore, it gives an inaccurate reading how far the wave traveled, its intensity, etc.  Another reason for biases is that the boat may be pitching, heaving, or rolling too much to get good data, which is one of the reasons one of the survey boats returned early today.

The POS MV aboard one of the NOAA ship RAINIER survey boats.

It’s impossible to eliminate all of the biases, however, there are measures incorporated into the data collection to minimize them.  One of the ways some of the biases are accounted for is the use of a system called POS MV.  There are sensors in the unit which record the movement of the boat and correct for these movements and their effect on the data. The POS MV also measures the vessel’s position with Differential Geographic Positioning System (DGPS) receivers, accurate to approximately 3 meters!  NOAA requires accuracy to within +/- 5m.  A regular GPS is only accurate to within 10m.  When you’re talking about making a chart of the ocean, it’s rather important to be more accurate with your location. Once all of the data is collected other technicians back on the ship process it. Processing the data helps in “cleaning it” to eliminate “noise”, therefore making the image a truer and cleaner representation of the sea floor.

Personal Log 

I had a chance to drive the survey boat today.  I really enjoyed that.  The driver is called the coxswain. There’s a small monitor mounted by the steering wheel, which shows you a chart of the area you’re in with an overlay of the survey lines. It’s the coxswain’s job to navigate the boat as straight as possible along each of the lines at a certain speed.  It looks a lot easier than it really is.  ENS Olivia Hauser displayed a few lines for me to practice on. I suppose if the water had been calmer and flat and there had been no wind it would’ve been easier. With winds of 15-20 knots and two-foot waves, it made it challenging to get the boat exactly on the line.  I did improve the more I practiced.

Science and Technology 

Another survey launch went out again today to do survey lines in Porpoise Harbor, which is where the RAINIER is still anchored.  A survey area is divided into sections by parallel lines. Depending on the already known depths of an area (based on existing navigational charts), the distance between each line varies. Shallower areas will have lines closer together, whereas deeper areas will have lines further apart.  It’s along these lines that the ship or the launch boat travels to acquire readings of depth as well as images of what lies beneath the water. The transducer, which is mounted on the bottom of the vessel, sends out a beam from the bottom of the vessel that forms a triangular shape.  The distance along the sea floor covered by this beam is called a swath. Underwater, these swaths overlap so that the area between all of the lines is actually covered, although the vessel only moves along the planned survey lines.  All of the data received is ultimately compiled and creates a visual image of the sea floor (bathymetry).  Tomorrow I’ll be joining a survey that will be out from 0800 until 1630.  I’m sure I’ll learn a lot more about data acquisition and how it’s processed once I’m actually doing it.

 A POD for today
A POD for today

Aboard the ship, a schedule is posted each day called the POD or Plan of the Day.  The POD can be found all over the ship so that everyone knows what his or her job will be for the next day.  In addition to identifying who will be doing what, the POD also shows the ship’s position, who the Officer on Deck (OOD) is, when sunrise and sunset will be for the following day, what time the high and low tides will be, the forecasted weather for that day, as well as any additional notes.  It is absolutely imperative ad expected that everyone knows what they’re supposed to be doing AND that they’re on time for it.

The POD for today had me scheduled for Deck Training.  I, along with the new people aboard the ship, spent the better part of the day learning how to handle the lines (ropes) that secure things, tying knots, and becoming familiar with the interior of the launch boats and their safety features. The part of the training that I enjoyed the most was learning how to raise and lower the launch boats from the ship.  I had to stand on the back (aft) of the launch and make sure that the large metal hook that lifted and lowered the launch was removed and put back on properly. This was not as easy as it originally appeared since there are specific things that need to be said and done at specific times, not to mention that the metal hook was extremely heavy and I was partially responsible for keeping it from swaying when it was dangling above my head. Because of the hazards involved in moving things overhead on the ship, it is absolutely mandatory that everyone wear a hardhat as well as their float jacket.  Safety is definitely emphasized.

Like almost everything on the ship, there is tremendous teamwork and communication involved in making sure the launches are moved safely and properly. For moving a survey launch I’d have to estimate that there are at least 9 people involved. Everyone works together like a very well oiled machine.  It seems that there are always people like Steve Foye (Boatswain Group Leader) or Jim Kruger (Chief Boatswain) watching to make sure all of the deckhands and others involved are doing their jobs correctly. Since so many jobs aboard the ship do depend on a team of people, it is critical that everyone is on time.  People get awfully upset if you’re late or not where you’re supposed to be.

The weather has been very favorable the past few days.  It was partly cloudy and sunny most of the day. Since Mother Nature has been cooperative, we were able to have a cookout on the fantail of the ship for dinner tonight.  The cooks definitely put out a spread for us. It was great sitting outside on the fantail, in the sun, enjoying the good food and company. It’s been challenging going to bed at night since it’s so light out so late, especially the past few days with the clear skies. Last night at 10pm it felt more like late afternoon.

Science and Technology Log 

We finally anchored later yesterday afternoon in Porpoise Harbor. It’s nice to have the ship in one place after 4 days of being underway.  I seem to be adjusting much better to the motion of the ocean. Today began with the first two launches going out at 0800 to begin the small boat surveying of this leg of RAINIER’S journey.  As long as the weather is good and there are no major issues with the survey launches, the boats stay out working from 0800 until 1630.

The smaller launches are able to cover areas that are shallower than the water’s the ship was surveying the other day since they have slightly different technology on them and because of their smaller size.  Each of the two launches had four people on them, a coxswain who drove the boat, and three other people who assisted with the hydrography surveying. One of the people is the head hydrographer, one works the computers that are collecting the data, and the other assists. Each day that launches go out, the people aboard them will rotate.  I’ll have my first chance at going on a survey launch in a few days. I’ll likely have a better understanding of the technical aspect of the hydrography once I’m actually on a launch.

I volunteered myself to join a launch boat that was heading to a small fishing village called Sand Point on the western side of Popof Island about 20 nautical miles away.  We left the ship at 1100 after getting water out of the launch.  Our ride to the village was a bit choppy since the wind was coming towards us and the waves were a bit higher.  It was very cloudy until we turned a bend.  All of a sudden, the sky was clearing and the water was calming.  As we reached the village, it was totally sunny and calm. YAY!! We only had about an hour in the village since our main reason for being there was to pick up a crewmember that had been on loan to another NOAA ship, the OSCAR DYSON.  It was great to just walk for a bit and eat some wild ripened salmonberries.

As we made our way back to the ship still anchored in Porpoise Harbor, the sunny, clear skies followed us. What gorgeous scenery!  There were also lots of puffins that flew over the water surface as we startled them going by in the boat. They’re such cute and funny looking birds with their chubby bodies and colorful beaks. Some of them had little tufts of yellow feathers on the tops of their heads.  We also had a couple of whale sightings in the distance. One was close enough that I could’ve taken a decent picture if I had had my camera ready.  Oh well. We had a special treat when we arrived back on the ship.  It was close to dinnertime and we were pleasantly surprised with a feast of the fresh halibut that Lt. Ben Evans (acting Executive Officer–XO) caught yesterday morning.  The cooks did a great job preparing the fish. Thanks to the XO and the kitchen!

Who’s Who on the NOAA ship RAINIER? 

Marta Krynytzky, an Assistant Hydrography Survey Technician, is the newest crewmember aboard the NOAA ship RAINIER.  This is her first cruise on the RAINIER as well as working for NOAA. Marta finished her Bachelor of Science degree in June 2005 in oceanography, specializing in marine geology and geophysics at the University of Washington in Seattle, WA.  After finishing college, she worked two cruises for Raytheon Polar Services Company. Her first cruise was to Antarctica as an intern aboard a ship called the Nathaniel B. Palmer.  Her second cruise, also to Antarctica, was aboard the Lawrence M. Gould where she worked as a marine technician.  Marta says that, despite how physically challenging the work can be aboard a ship, the two previous cruises she’s worked on were half female.

Marta enjoys doing fieldwork, which is one of the reasons she wanted to work for NOAA. She looks forward to seeing different places and trying different positions within NOAA. When she’s not working, Marta enjoys hiking, backpacking, snowboarding, skateboarding, canoeing, and surfing. From her experience, Marta believes there are a few important requirements for the kind of work she does. As far as coursework, she believes a strong math background is important.  In addition, computer skills are needed as well as having working knowledge of programs such as Excel for organizing data, preparing spreadsheets, and creating graphs and charts. Another important quality for working on a ship is being able to work as a team with other people.  Much of the work involved living and working on the ship is not done independently. Everyone relies on everyone else to keep the ship running smoothly so the objectives of the ship can be met.

I wish Marta the best of luck on her new career with NOAA!!

Science and Technology Log 

Today began with clear, blue skies and calm water.  It was a very welcome change for me from the rocking and rolling we’ve been experiencing as well as the clouds and drizzly rain. Since we finished all of the survey lines that were planned for the Semedi Islands area, we are now underway to our next survey spot in the Shumagin Islands which we should reach and anchor at by this evening. We did some “biological sampling” this morning as several crewmembers cast their fishing lines off the fantail (back) of the ship.  Since the first spot wasn’t producing as expected, the ship was moved to a second notable location. Within minutes of the fishing lines being out into the water, 4 halibut and 1 Irish lord were on deck. The Irish lord was put back into the water, but the halibut were filleted on the deck.  Maybe that’ll be dinner one night!!!

Another nice surprise this morning were the sightings of whale in the distance as they blew water and swam around.  A pod of Dall’s porpoise also played again on the bow (front) of the ship for a while.  I felt like they knew I was watching them so they were showing off.

Who’s Who on the RAINIER? 

There are many roles that people have aboard the RAINIER, all of which collectively keep the ship running safely and efficiently. Steve Foye has been a member of the RAINIER crew for approximately 15 years, but has been with NOAA for over 25 years. He has worked on other NOAA ships, including the McARTHUR, the DAVIDSON, and the FAIRWEATHER. Steve’s original ship training came from his “on the job” training he received being in the Navy and from working on freighters. Prior to working with NOAA, Steve worked for Boeing in a guided missile factory.

Steve’s title on the RAINIER is currently Boatswain* Group Leader. He reports directly to the Chief Boatswain and has a number of deckhands onboard that report to him. The Boatswain is in charge of a ship’s anchors, lines, wires, the deck crew, the ship’s boats, the rigging of the ship, and overseeing the general maintenance of the ship. The specific tasks that Steve oversees on the RAINIER are imperative to the functioning of the ship. All of the ship’s wires need to be slushed, which means they are greased regularly to keep them from rusting. There are quite a lot of wires on the ship to hold things in place as well as to move equipment around using cranes.  All of the mechanical equipment on the deck must also be lubricated and kept in working order, including the davit winches, cranes, and anchor windless, which controls the anchor. In addition to maintaining this equipment, the Boatswain and his crew are the ones who also operate the equipment.  Steve mentioned that “chasing rust” was another important part of the ship’s upkeep.  This is where rusty areas are prepped with a wire brush to clean them. Then they’re-primed and repainted.  General maintenance of the ship is something else the Boatswain oversees, making sure that the passageways and general interior of the vessel are clean.

On the RAINIER there are 6 survey launch boats.  It is Steve’s responsibility to make sure that the boats are launched properly. This involves some safety checks ahead of time as well as the use of davits, which are machines that lower the launches into the water.  It is critical for the hydrography work that the RAINIER does to keep these boats and the equipment that maneuvers them on to and off of the ship in working order. When Steve isn’t busy training someone new to the ship or overseeing the use of a crane or davit, he enjoys taking photographs. He told me he has over 2000 pictures so far this year alone! He enjoys being away from home cruising to new places. He has maps that he marks to show the places he’s been to on all of his cruises. From talking with him, it seems that Steve enjoys sharing his knowledge and experience with others. He’s also a very funny man.

Science and Technology Log 

The purpose of the hydrography work that the RAINIER is doing is to collect data using sonar readings of the ocean floor to provide a picture of the topography of what’s under the water, otherwise known as bathymetry.  Are there volcanic pinnacles or other underwater hazards that we are unaware of? Updated NOAA charts need to be made to show more detail and the complexities of the waterways due to a large increase in Pacific Rim ship traffic between Asia and North America.

We began surveying the Semedi Islands area from the ship today.  At 0800 a crew went on to the fantail (back deck) of the ship to lower a device called a CTD.  This canister-like apparatus takes measurements of Conductivity, water Temperature, and Depth, from which the speed of sound through the water can be calculated.  These measurements are taken every 4-6 hours and are used to calibrate the readings taken by the ship’s multi-beam sonar mapping system.  For a few days we will continue to do these ship surveys since the water’s depth is greater in this area. The ship’s sonar can cover a wider area at a lower resolution than the smaller launches that we will use to survey the shallower waters in the Shumagin Islands.

The area inside the square being pointed to is where the NOAA ship RAINIER is surveying to take measurements of water depth as well as to locate any underwater features such as rocks and volcanic pinnacles.

ENS Sam Greenaway, who is a Navigational Officer, spent time showing me nautical charts of the areas that we will be working in.  There is a lot of very important information found on these charts, which are used by anyone operating a vessel on the water (fisherman, Navy ships, Coast Guard ships, cargo ships, etc.).  In addition to showing water depths, these charts show where there are lighthouses, rocks, ledges, buoys, coastlines, and other potential hazards or physical locations.  A ship like the RAINIER relies on these charts as a means of planning a route to follow.

Personal Log 

I had a good night’s sleep last night.  I think the gentle rolling motion had something to do with it as well as the sound of the water lapping up against the ship. I only wish the rolling and swaying motion I feel was so comforting during the day! After getting sick this afternoon, I finally gave in and took some seasickness medicine.  I might have to take it everyday if I’m getting sick in rather calm seas. I did find out that once we get to the Shumagin Islands in a few days we will be anchored.  I’m definitely looking forward to that. Earlier today there were three Dall’s porpoise riding the bow of the ship. They like to play and swim along the wake of the ship as we move forward.  Yesterday there were some sea otters spotted as well as several clusters of puffins. We’ve been told on the RAINIER’s last trip to the area we’re going that there were a lot of humpback whales.  I’m keeping my fingers crossed.

We had our first fire and abandon ship drills today. Safety has definitely been emphasized by the location of safety gear around the ship, the requirement for wearing hardhats and float jackets when on deck, and the safety drills. We all have these papers called bunk cards that we must hang on our bunk beds in the stateroom.  The cards tell each person where they should muster (meet) on the ship for each type of drill as well as what type of extra gear they are responsible for bringing.  I needed to photocopy my card to carry around with me since I can’t remember exactly where I’m supposed to be for which drill. The sun broke through this afternoon….very exciting.  It’s been very cloudy and drizzly ever since I arrived on Saturday.

Keep shining sunshine!

Personal Log 

Right after breakfast this morning we had a safety demonstration by the Deck Utilityman Kenneth Keys. The five of us who are the “newbies” on the RAINIER for this leg had to be issued a life vest, a float jacket, and an immersion suit, otherwise known as a “gumby suit”. Of course, it’s not enough to just have this safety equipment, we also needed to put it on. The immersion suit was quite an experience to say the least.

By 1600 hours today we were departing Kodiak Island to begin our cruise to the Shumagin Islands.  As we were leaving the dock, I stood on the fly bridge to observe the deckhands at work. It’s quite an undertaking to depart port.  There’s definitely a lot of teamwork involved.  As we were making our way into Chiniak Bay, I stood on the port side of the ship (which is the left side) talking with ENS Sam Greenaway.  He pointed out to me the red buoys that we were passing which were on the port side of the ship. The buoys basically serve as a guide for the ship in areas where they may be shallow waters such as he channel we were passing through. In the United States, as a ship is leaving, the red buoys should stay on the port side. If we were returning, the red buoys would be on the starboard (right) side of the ship.

As we started getting into a bit rougher water, I really started feeling the pitching and rolling of the ship. The pitch is the forward to backward movement and the rolling is the side-toside movement.  Many of the crewmembers had taken some medication earlier to avoid seasickness.  I was not one of them.  Gradually I became dizzier and dizzier and started to feel nauseous. I stood on the bridge for a bit and watched the horizon before I finally found an empty couch and just laid down.  The bridge is the part of the ship where the ship’s navigational controls and other essential equipment related to ship operations are located and operated. Hopefully I develop my “sea legs” and I can avoid taking any of the seasickness medication.    

Tomorrow we’re supposed to begin doing some ship hydrography which means that all of the work that will be done will be from the ship itself and not from the smaller launch boats that are also used. I’m excited to see how all of the cool technology works.

Personal Log 

Hello! I finally arrived on Kodiak Island yesterday after 3 different planes and a 4hour time change.  I was met with a smile by Ensign (ENS) Jamie Wasser who brought me to the RAINIER, which is currently docked at the Coast Guard base here on Kodiak Island until our scheduled departure on Monday, July 24. As we approached the ship, ENS and morale coordinator Olivia Hauser greeted us and invited me to join a group to go out for sushi.  I started jumping up and down–SUSHI!!! I can only wonder what thoughts were running through her head, as this was our very first meeting.

After quickly being shown my “home” for the next 3 weeks and meeting Jackie Hams, the other Teacher at Sea who is on the cruise, we all piled into the shuttle van to go for our sushi dinner. I immediately felt comfortable as we talked and laughed.  I was also growing more and more tired as I had been up for almost 24 hours at this point.

After returning to the ship, I met my roommate Dorothea “Doe” Mackey, one of the stewards who works in the kitchen. I unpacked and had a tour of the vessel.  Initially I was a little overwhelmed by all the twists and turns and stairs, but after exploring for a bit, I’m getting more comfortable with the maze.  Since we’re not scheduled to leave here for another day, I’ve had some time to get acclimated and talk with many of the crew.  So far the crewmembers I’ve met have been very friendly, informative, and helpful.  There are some very interesting personalities on board. •

Being a rather tall individual, the close quarters will take a little getting used to.  I have the top bunk in my stateroom.  I usually like the top bunk, however, this one will take some getting used to.  The ceiling is about 2 feet above the bed, which makes for quite a claustrophobic experience. It took me about 10 minutes to get down from the bunk this morning since I couldn’t sit up and I kept hitting my head on the ceiling.  My apologies to Doe if I woke her with all of the ruckus.

For the past 30 hours the FAIRWEATHER has been on route back to port. We had beautiful weather most of the way back, which made it perfect for whale watching. Yesterday evening, many of the crew made their way out to the ship’s bow to watch at least 8-10 humpback whales swimming around the ship. It seemed like everywhere you looked, you saw another whale spout. It was quite exciting, as we all were snapping pictures trying to get the perfect shot. Unfortunately, they were just a little too far away. Later in the evening, the ship stopped to let some of the crew (those with valid fishing licenses) get a chance to do a little fishing. Several had good luck in catching halibut, before the ship had to continue on the voyage back to port. The FAIRWEATHER arrived back at port today at 11:00am. This gives the officers and crew time to prepare for tomorrow’s Fleet Inspection.

Emily works in the Deck Department where she is responsible for a variety of duties. She is in charge of cleaning and general maintenance of the ship as well as operates cranes, stands bridge and anchor watch, and pilots the small boats (she drove the survey launch I was on). Not a position you might expect from someone with a B.S. degree in Physics!

Emily grew up in New York, close to Lake Ontario, and raced sailboats competitively. After college, Emily soon realized she wanted to get back to what she loved doing – sailing. She spent the next five years working on sailboats, primarily teaching environmental science classes aboard educational vessels and sailing skills. But she wanted to work with serious boat people. After discounted shipping out commercially, feeling it wouldn’t be stimulating enough, she looked into NOAA. It became a perfect fit!

Working for NOAA has everything Emily was looking for – a serious, science oriented experience that has a lot of variety and opportunities. She actually heard about NOAA through her older brother, Ben. Ben happens to be the Field Operations Officer on the RAINIER. So it is very comforting to know she has family close by. Emily loves being on the water and driving the small boats. She feels very fortunate to be able to see parts of the country like Alaska that very few people get a chance to see. For now, she is just savoring her time aboard ship. She is studying to get certified for the survey department which will provide many more opportunities for her in the future.

Personal Log 

I’ve had a wonderful ten days in Alaska!  I want to thank everyone at NOAA and especially the officers and crew of the FAIRWEATHER for allowing me to join them for this leg of their hydrography season.  The knowledge I’ve gained from this experience will be shared with my students for years to come!

Science and Technology 

Today was the last full day of hydrography before heading back to port. The ship planned to take full advantage of the time.  Starting off at 8:15, the small Ambar boat aboard the FAIRWEATHER was launched. The Ambar is about 20 feet long with a shallow reinforced hull to make it ideal for getting even closer to shore than the survey launches. The Ambar’s mission is to check for hazards close to shore that were previously detected. While the Ambar is out working the coastline, the FAIRWEATHER continued surveying in the deeper water, making it a very productive day.

The Ambar boat heads out to see if certain hazards detected by LIDAR were accurate. Several days ago, the FAIRWEATHER welcomed aboard a senior hydrographic surveyor, James Guilford, from the Tenix LADS Company. He was here to support his product – LIDAR. NOAA works with several independent companies that uses a different hydrographic technology called LIDAR. LIDAR is a laser that is used from planes rather than boats. These planes generally fly at between 1,200 and 2,300 feet along mainly coastline, to survey those difficult areas that are hard to reach by boat. The LIDAR can generally reach water depths of 20-25 feet and can be used 24 hours a day. The only drawback is that the LIDAR has trouble penetrating the water surface when there are obstructions like heavy kelp areas or whitewater. However, between data collect from the boats and planes, NOAA can create a very complete survey of an area.

Personal Log 

I have been amazed at how smoothly the ship operates 24 hours a day. It can be a bit overwhelming watching the crew head to their posts and rotating through the mess hall throughout the day. At first, I found life at sea a bit of an adjustment, but then you fall into a routine and it becomes easier.  As a visitor to the ship, it can be a bit hard because you have no set role. Those crew members new to the ship that have a specific job seem to quickly adjust. I don’t know if I would ever make a very good sailor, but it is fun to get a little taste of what it is like at sea.

FAIRWEATHER Profile: Commander Andrew Beaver

The FAIRWEATHER recently underwent a change of command. Commander Andrew Beaver officially took command in June of 2006. The FAIRWEATHER is fortunate to have been assigned such an experienced commander. However, you would never have expected it based on his upbringing. Commander Beaver was born and raised on a 180 acre farm in Iowa, where his family raised corn, soybeans, and pigs.  In fact, he could easily have followed his father’s footsteps and become a farmer.  However, he went on to Iowa State where he graduated from Agriculture Engineering. After graduating, jobs were not readily available, so Commander Beaver pursued the NOAA corps. It provided many unique opportunities and he took to life on a ship right away.

Before joining the FAIRWEATHER, Commander Beaver was assigned to a variety of posts including service with the NOAA Diving Program office, Navigation, Field Operations and Executive officer of the WHITING, and also Commander of the NOAA ship RUDE. Commander Beaver and his family are delighted to be here in Alaska.  Everyone is very nice and his home port in Ketchikan even reminds him of the small towns in Iowa where he grew up. His family loves the beauty and wildlife of Alaska.  He feels it’s a wonderful place to bring up a family.

He is enjoying the new challenges of his new job and getting to know the ship’s crew.  The surveying has been different because the coastline is more sheer in Alaska, whereas on the east coast it tends to be more gradual.  He loves the fact that there is a lot less boat traffic on the water and that the remoteness of his survey work forces the ship to be more self-sufficient.

NOAA provides employees a variety of opportunities.  Commander Beaver always enjoyed knowing that every 3-4 years he can move on and try something different.  He would encourage any student interested in the math and sciences to look into employment opportunities like those found with NOAA.  NOAA allows you to “make a difference in the world” and you would be “doing something that your parents and grandparents would be proud of”!

The ship has been on “24-hour Ship Hydro” all day, and for the foreseeable future.  When the weather is a bit rough, like we have now, we can not send out the smaller boats to survey areas closer to shore. This rougher weather, however, is not a problem for the well-built FAIRWEATHER.  Each day, the navigational officer and the survey technicians decide what area in the deeper water needs surveying.  This area is then further broken up into smaller, more manageable polygons.  Each small polygon is created based on the expected depth of the sea.  They try to make the smaller polygons of similar depths.  The FAIRWEATHER can then can pass over these areas using similar radar to that used on the smaller survey launches, except radar more appropriate for deeper water. The FAIRWEATHER can continue this mapping of the ocean bottom around the clock for many days in a row.  When the weather starts to calm down, the ship will then return to more off-shore surveying.

Personal Log 

While out in deeper water, I’ve enjoyed standing on the bridge watching and looking out over the ocean. Today we were fortunate to see humpback whales playing in the waters close to the boat. First, you spot the waterspout shooting out over the water’s surface. Then if you’re lucky, about a minute later you’ll see the whale breech, or jump out of the water.  When a whale breeches, a cheer is heard from everyone in the bridge, as it’s a special show for even the experienced sailor.  The two types of whales most common in the area are Minke and Humpback whales, but I’m still holding out hope I’ll see some Orca’s!

FAIRWEATHER Profile: Physical Scientist Megan Palmer Megan is one of three physical scientists currently aboard ship. She actually works at NOAA’s home office in Seattle but rotates out to ships several times each year. She is currently spending six weeks on the FAIRWEATHER and earlier in this year spent a month out at sea in Hawaii with another NOAA ship. Her role on the FAIRWEATHER varies. She’s primarily here to offer support wherever needed. She helps review survey’s, train employees, helps facilitate communication between the ship and home office, as well as increase her own awareness of what goes on aboard ship.

At an early age, Megan wanted to be an architect.  However, she was always interested in the math and sciences.  In college at Frostburg State she greatly enjoyed taking environmental classes which eventually led her to a degree in geography. It wasn’t long before Megan found a position with NOAA and has been very happy ever since. She loves being on water, although she admits it can sometimes be a love/hate relationship. At times you just want off the boat.  But the ability to use her geography background and the many opportunities NOAA offers employees, really excites her about this job.

For those girls thinking about a possible career with NOAA, Megan says, “Go for it. Don’t be intimidated by math and science courses.”  After all, one third of the personnel aboard the FAIRWEATHER are female, including women in the deck department, officers, survey department, and scientists!

So I survived the trip across the Gulf with only some minor sea sickness and for the last couple days been having an incredible time with the crew of the RAINIER on Kodiak Island. The island is very green and we’ve been so lucky to have beautiful sunny weather.

The NOAA ship FAIRWEATHER, RAINIER’s sister ship, is in port as well. On Friday there was a Change of Command ceremony brining in a new Commanding Officer for FAIRWEATHER.  I visited the FAIRWEATHER today and it looks almost identical to RAINIER.  Seeing the ships docked side by side is pretty impressive.

Tomorrow I fly home to the Big Island and I just can’t believe how fast the time has flown by. I finally know my way around the ship and now it’s time to leave. I do want to say, as this is my last log, how grateful I am to have had this experience.  I have learned an amazing amount on a variety of different subjects and truly feel myself enriched both personally and professionally.

The crew of the RAINIER has been amazing! I can’t thank them enough for welcoming me aboard the ship and letting me hang with them these last couple weeks.  Everyone has been extremely generous with their time and has taught me an amazing amount!!  I am leaving the RAINIER, having made some great new friendships.  I feel sad to be on my way so soon, but very excited to share all that I’ve learned with my students at WHEA.

Thanks again to everyone at NOAA for providing educators with such a unique opportunity to live and work together with NOAA mariners and scientists!  It’s been great! I’d just like to know, when can I go again?

Mahalo and Aloha!! Jessica Schwarz

The ship is underway, heading across the Gulf for Kodiak and to be honest the more I type the queasier my stomach feels so I’m keeping this entry short.

The seas are not rough today, I think they said between 5-7ft. swells, but the rocking of the ship has me feeling sick to my stomach a little bit.  I guess the more time you spend up top of the ship, the worse you might feel.

I went up to see the action in the bridge while we’re underway.  Able-Bodied Seaman (AB) Leslie Abramson let me take the helm for a few minutes.  There are several compasses to watch, basically all at one time, telling you the course you are on as well as your degrees of course change. Since we are in open ocean there were no useful landmarks to point towards to help me stay on course.  It was a very neat experience to be at the helm of the RAINIER.  She is a huge ship and it’s pretty incredible to feel her move with such small turns of the helm.

Okay, that’s all I’ve got. I’m not feeling too well and probably should find some motion sickness medication.  I’m eating my words of my last log and caving.  I’ve decided being a zombie beats feeling sick.

Just so ya know 

I threw up my dinner after finishing this log and with the garbage can at my bedside I slept quite well.  So, even after having taken sea sickness medication, I’m still puking…what’s up with that?  I guess there’s just no preventing these things  sometimes.

Personal Log 

Just when I think I’m getting the hang of things on the ship…. I was working at the computer when I heard myself being paged over the intercom, “TAS dial 128”, “TAS dial 128”. I looked around and didn’t see a phone so I wondered up to the galley. The crew is prepared for the TAS to be confused and lost most of the time I think, so it doesn’t take long after a confused look on your face to get some help.

I was being paged because the CO wondered if I’d like to take a boat ride over to Redoubt Lake where the sockeye salmon are spawning.  I hurried down to my stateroom to grab some warm clothing and made my way to the fantail (stern of the boat) where the skiffs are tied.

Redoubt Lake is a beautiful freshwater lake that sits just above sea level on one of the nearby islands. There were several other boats anchored in the bay, one of which had two men fishing for sockeye.  The CO cast a line in as well, but I guess the salmon weren’t biting today.  On our way back, I got to drive the skiff…remember the skiffs go much faster than the survey launches. The one we were riding in today can get up to 45 knots. I didn’t drive it that fast though.

We saw a harbor seal poke its nose out of the water. That was really cool! I’ve seen pictures some of the crew has taken, where they are resting on land. Pretty amazing! When I came back to the ship I headed up to the plotting room where Physical Scientist Shyla Allan showed me some amazing sonar images.  I’ve included a couple in this log for everyone to see. I was very impressed by how detailed the images are!

Later on that evening, I went for another boat ride on one of RAINIER’s skiffs with ENS Megan McGovern, OS Megan Guberski, and ST Erin Campbell.  We headed back over to Redoubt Lake. We spent time watching the salmon jumping.  Pretty incredible! Tomorrow we will be underway and heading across the Gulf to Kodiak Island!  Think good thoughts of calm seas and settled stomachs for me.

Science and Technology Log 

So I hope everyone remembers what RAINIER’s Captain, Guy Noll, told me last week before I went out on a launch: “We hit rocks so that you don’t have to.”  When I first heard him say this, I kind of laughed, figuring it was somewhat of an exaggeration, he was only kidding with me. I found out this morning he actually wasn’t.

An added component to running lines and collecting sonar data is doing nearshore feature investigation. If you are involved in feature investigation, your job is to either prove or disprove whether or not a feature (rock, ledge, islet, wreck, etc.) actually exists in the position it’s been historically claimed to be.  When I say “historically” I mean some of these features were last charted based on data collected in the 1940s or earlier.  Therefore, NOAA needs to update the data used in developing their charts and resurvey various areas with updated technology.

For the last several years, NOAA has been augmenting its ship-based sonar surveys with airborne bathymetric LIDAR (LIght Detection and Ranging) data. LIDAR uses high powered laser pulses (invented in 1962!) transmitted from aircraft.  The laser sweeps back and forth across the earth’s surface, and the reflections are detected by a receiver. Much like sonar, the distance to the ground can be inferred from the amount of time required for the light to travel from the airplane, to the earth, and back.  If the position and altitude of the airplane are measured very accurately, the height and shape of features on the earth’s surface can be determined.

NASA and the U.S. Navy were among the first to use airborne LIDAR.  Later, with the involvement of NOAA, Airborne Oceanographic LIDAR was developed for use in the marine environment.  After continued progress in development and technology, Airborne Hydrographic LIDAR (AHL) was invented. AHL uses a wavelength of light which penetrates the water rather than reflecting off the surface, allowing for measurement of water depths in addition to land topography.  Keep in mind that although ALH was first developed in the mid 80s it was not practical for utilization on the Alaska Peninsula until the 90s. Although an exciting new addition to NOAA’s hydrographic survey “toolbox”, LIDAR is not able to run nearly as deep as sonar. In shallow water close to shore, however, it can reduce the need for inefficient and potentially unsafe small boat operations.  Both LIDAR and sonar are used to assist in determining what features are navigationally significant to those at sea and essentially what features will end up being charted.

RAINIER receives a list of questionable sea features based on information collected from LIDAR, past hydrographic data, and in some cases reports made by mariners.  Based on this collection of data, they are asked by the Pacific Hydrography Branch (the folks in Seattle who compile RAINIER’s data for addition to the charts) to investigate certain features (i.e. rock, ledge, islet etc.) that cannot be resolved with certainty based on the LIDAR or other.

So, today, ENS Sam Greenaway, ENS Jamie Wasser, Seamen Surveyor (SS) Corey Muzzey, and I went out looking for rocks☺. That doesn’t sound nearly scientific enough does it? There’s a lot involved in looking for rocks actually, and it’s not nearly as easy as it might sound. For me, as someone new to hydrographic surveying, my big question was, “Okay, and then what happens when we find one?” What’s this whole, “hitting rocks so you don’t have to” idea? Do we really hit the rocks? I rode today in launch RA1 to do investigations.  RA1 is unique because it is a jet propelled boat. This means it does not use a rudder and propeller, like you would expect to find on most power boats. Instead, RA1 is propelled (and steered) using water that is sucked in through a grill in the hull of the boat, accelerated by an impeller driven by a diesel engine, and expelled out a nozzle in the boat’s transom. Changing the direction of the discharge nozzle is what steers the boat. This allows RA1 to go into much shallower water. In fact it only needs 1 foot of water to stay afloat and move around.  Also, don’t be fooled by me saying “jet propelled”.  That might give someone the impression these boats are extremely fast.  RA1 is actually quite slow, with a cruising speed of 12 kts, which I figure was good for the crew while I was at the helm.

There are different ways of investigating features and doing a disproval (determining if a feature is there or not).  One is to use RA1’s single-beam sonar.  This is different from multi-beam sonar (like what I’ve discussed before) because instead of sending out between 140-250 pings of sound over an area of between 120°-150° from the boat, single-beam sonar sends only one ping directly beneath the hull to the ocean floor.  While single-beam sonar is running, the echosounder printer draws an outline of the sea floor features. Check out the picture of ENS Jamie Wasser with the echosounder to get an idea of what it might look like.

If you’re wondering why they aren’t using multi-beam instead, it’s because they’re in shallow water, extremely close to rocks, and it would be much too easy to knock off the multi-beam transducer attached to the hull.  Multi-beam sonars cost around $300,000 so it wouldn’t be very cost effective for NOAA to lose or damage one.  The single-beam sonar is imbedded in the hull and won’t be knocked off if the boat does happen to hit a rock.

Not all survey boats were running item investigations today. In fact today three survey boats were launched, two launches were running main scheme lines with multi-beam sonar (what I’ve participated in on past days) and one, the launch I was involved with today, was running investigations.

In order to do this, the launches need to get extremely close to shore and extremely close to these “hypothesized” features, often times physically nosing the boat up to them to check the positions (remember, “we hit rocks so you don’t have to”).  Depending on the sea conditions, this can be a very difficult process.

Personal Log 

Today was an excellent day. It was beautiful and sunny all day. We stopped the launch and had lunch in one of the little bays. On our way home, SS Corey Muzzey let me drive.  The jet drive boats drive much differently than the boats with rudders and propellers. The helm didn’t feel nearly as touchy and seemed more forgiving of my exaggerated turns of the wheel ☺. We saw several humpbacks out there today…around the time whales started showing up near the boat was when I lost interest in driving.

The landscape here is so incredible.  I keep trying to take digital pictures of it and am always disappointed by what little justice the pictures serve. Tonight is a crew beach party. Everyone on the ship who wants to go can get a ride to a nearby beach to spend some time on land for a change. I’m looking forward to it!

Soon we’ll be crossing the Gulf. I’ve been hearing some horror stories about this crossing, not just from the crew, but also from some of the people I met while I was in Sitka before I came onboard RAINIER.  I’m actually looking forward to being on the open ocean. We’ve spent a lot of time anchored and well protected in the bay.  Crossing the Gulf will be a new experience.  I’m excited!

Calling All Middle Schoolers-We Need Help Answering a Few Questions! 

Sonar technology wasn’t utilized for hydrographic purposes until the 1940s.  Before this, how did surveyors chart the sea floor? Remember, hydrographic surveying and the development of nautical charts, dates all the way back to 1807 with Thomas Jefferson.  So, how did they do it back then?  Let me know what think!

Science and Technology Log 

Today the RAINIER moved yet again. At around 2:00 this afternoon, while I was working away in the plotting room we lifted anchor and got underway.

I learned today the anchor lengths are measured in units called “shots”, with 90 feet in one shot. As the anchor was being lifted, you could hear Boatswain Group Leader (BGL) Steve Foye calling out shot lengths over the radio.  This was to let the crew in the bridge know how much anchor chain was left before the ship was no longer be secured to ground. ENS Meghan McGovern mentioned that the anchor chain is generally let out 5-7 times the depth of the water, leaving plenty of slack for the ship to rotate on anchor.

Two survey boats were still in the field when RAINIER got underway today. I think it’s pretty amazing they can load the boats onto the ship while we’re moving!  According to the crew it’s easier to load them while we’re moving then when we’re at anchor.  ENS Olivia Hauser radioed the launches to let them know to get ready for pickup. We’re now anchored in Kanga Bay again and the weather has been beautiful!

Tonight I had the opportunity to chat with some of the NOAA Commissioned Officers on the bridge, ENS Megan McGovern, ENS Nate Eldridge, and ENS Sam Greenaway. I wondered how they got involved in NOAA Corps in the first place. All three of them received a Bachelors of Science prior to applying to NOAA Corps. One of the minimum requirements to apply for the Corps is a bachelor’s degree in science, engineering, or mathematics.  Once admitted, the officers head to the U.S. Merchant Marine Academy in Kings Point in New York for NOAA Basic Officer Training Class, a rigorous three-month training period. Upon completion of BOTC, the NOAA Corps officers are placed on NOAA vessels sailing throughout the world.  They commit to a 2-2.5 year tour aboard the ship to which they are assigned.

The officers, always in uniform, are responsible for running the ship, and are also hydrographic surveyors onboard RAINIER. They work on a rotating schedule, including anchor watch, survey launch, and cleaning and processing data. It seems to me that they’re always working. Then again, that’s how it seems with all the crew working onboard the RAINIER.  Check out the NOAA Corps web site if you’re interested.

It’s Sunday today! Physical Scientist Shyla Allen asked me today what I would typically be doing on a Sunday. I told her, I’d be at the beach, going for a swim or snorkel!  It’s funny how different my Sundays are in Alaska on RAINIER.  It doesn’t really feel like a Sunday because everyone is still hard at work.  Today I wrote my log, responded to e-mail, and visited with crew.  Pretty fabulous Sunday, really.  Not too much activity, at least not for me anyways, which is just how I prefer to spend Sunday.

Calling All Middle Schoolers-We Need Help Answering a Few Questions! 

This question comes from the Navigation Officer onboard RAINIER, ENS Sam Greenaway.

If there are 6ft in 1 fathom, in 15 fathoms of water, how many shots of anchor chain would be let out when the anchor just touches the ocean floor?

Also, in 15 fathoms of water, how much additional chain would typically be let out to provide slack for the RAINIER to swing on anchor?

The crew is working hard to finish sheet B, which is full of completed polygons, with a few remaining to be worked on. Launch 1018 went to work on three of those areas today. Captain Ron drove us to our destination and ENS Wendy Lewis started the computer system. Two of the areas we were assigned were low water areas that can only be navigated by an experienced cox’n. Good thing Ron was heading up our boat. He is as experienced as they come. To start our work we had to lower our transducer, which enables us to send out sonar beams that bounce off the ocean floor. Those beams bounce back to show the shape of the ocean floor.  We deployed our CTD (conductivity, temperature, depth) device three different times to get accurate readings on the conditions of the ocean that might affect our data collection. Surprisingly, we completed our assignment early and got to head in for lunch.

Today was whale day! Captain Ron promised me whales and he delivered even before we heading out this morning.  As we stood on the fantail of the ship for the morning meeting, Ron pointed out a humpback breeching off in the distance!  Then as we cruised at 8 knots surveying our area, a large humpback put on a great show for us!  He surfaced again and again, showing off his immense tail fins. What a large splash he made!  I was able to watch him for nearly thirty minutes and captured some great video of the spectacular scene.  I had yet to see the grand prize of Alaskan marine life: the Orca, but whale day wasn’t over yet. As we idled off the northwest corner of Andronica Island completing our data for the day, a small pod of orcas came to play between our boat and the coast. I could see the white patch on their side and their characteristic dorsal fin. I was so thrilled!  Again, I had an amazing day out in the Alaskan seas. Am I really going to have to leave here?!?

Personal Log 

I spent another day of hydrographic surveying today! We started at 8:00am by launching boats RA4 and RA5. I was on RA5 today.

I took a motion sickness pill the night before because the seas have been pretty rough lately and some of the technicians have gotten sea sick. I had no idea how I would feel so I took one just to be safe and let me just say…I am never taking one again. I felt like a zombie woman the entire day. I haven’t gotten sea sick yet and I think I’m going to take my chances next time the opportunity arises.  I’m sure the medicine has different effects on different people, but for me, I felt like my head was floating a foot above my body the entire day. We’re going to be crossing the Gulf next week and rumor has it that can be a rough leg so I might eat my words and cave by taking the medicine. In that case, it will make for an uneventful log. After a day of surveying we came back to the ship, had dinner, and then I was off in a skiff to shore to spend some time in the hot springs.  WOW! This was amazing.  When I was packing for my trip I remember thinking it was pointless to pack my swimsuit, but I did anyways…because ya never know! Turns out, I needed it for my visit to the springs.

Tucked away in the forest on one of the surrounding islands encircling the bay are beautiful hot springs that people can come to enjoy.  The US Fish and Wildlife Service built several small cabins that enclose a big round brown tub, similar to what you’d see in old country western movies.  White pipes buried underground are hooked up to the natural spring water and pumped into the tubs.  The cabin has a huge window so you can view Hot Springs Bay from the tub.  It was like a rustic Alaskan spa experience!  After spending some time in the tub, Survey Tech Erin Campbell and I went up into the forest a little ways where we found a natural hot spring surrounded by hemlock trees.  The bottom of the hot spring was pretty muddy and crunchy from what I am assuming (and hoping) to be twigs and leaf litter.  I couldn’t help but wonder what other little organisms were having an Alaskan spa experience along with me.  I came out a little muddy, but very relaxed!

These are the kinds of amazing experiences the crew of the RAINIER gets to enjoy while traveling onboard the ship. They are visiting places that most people will never get a chance to visit in their entire life.  There are fishing poles, kayaks, surf boards, and all kinds of other equipment onboard that the crew can use!  I think that’s awesome.  Everyone is working so hard during the day; it’s nice to see they have some options for things to do on their down time.

I have to say, I have been so impressed with everyone onboard the RAINIER.  This is a group of adults who live together, work together, and then play together…all in very close quarters. Everyone is very well rounded and kind.  They are truly professionals at sea. I really am appreciating the competency and maturity of everyone onboard the RAINIER. There is a common understanding that although you have high expectations placed on you to get the job done, there is also an understanding that everyone is always learning and it’s okay to make mistakes here and there.

I think that is extremely important to support the crew’s confidence and comfort level in performing their duties while onboard.  I’m just so impressed with the level of support and encouragement of one another.  This is not something always observed onboard a boat or ship. I think it says a lot about the high quality of the crew onboard the RAINIER. I feel lucky to be a part of it for my time at sea in Alaska.

Next log, I’ll explain more about how the hydrographic data is processed after it’s been collected on the launches.  For now, I am off to see how things are going in the bridge, which I have decided is my favorite place on the RAINIER…well, the bridge and the galley, where the coffee is always flowing.

Calling All Middle Schoolers-We Need Help Answering a Few Questions! 

What is a hot spring?  How are they formed and where does the hot water come from?  Isn’t water in Alaska supposed to be cold? Also, just out of curiosity, what kinds of things might live in a hot spring?

Crew Interview Day! 

Today was another excellent day onboard the mighty RAINIER.  I awoke and made my way to the galley for an English muffin and some coffee before I made it to Central Engine Room Control to chat with Third Assistant Engineer Kelly Baughman.  Before Kelly made her way down to talk with me, Engineering Electronics Technician (EET) Joe Gallo took me beyond the center console and into the engine room.  I was able to see for myself the machinery that is powering the ship.  I checked out the main engines, the generators, the boiler, the evaporators, and all kinds of other noisy machines.  After my tour I sat down to find out what got Kelly into being an engineer in the first place. Kelly started out as a young girl with aspirations of becoming a naval pilot. This was interesting news to me because I didn’t realize the Navy had pilots in the first place.  I thought the Navy aircraft carriers were carriers for Air Force planes.  In actuality, the Air Force is only land based, and all Navy carriers support naval aircraft.

Photo of the port main engine. The starboard main engine is not shown but looks exactly the same and is directly across from the port engine.

As she grew up she changed her mind, deciding to pursue a Bachelors of Science in Marine Engineering Systems Design from the U.S. Merchant Marine Academy in Kings Point, NY.  Along with a BS, Kelly also received a minor in nuclear engineering.

The United States Merchant Marine Academy (known simply as “Kings Point”) is one of the five federal military training academies.  It is the only academy that allows its graduates to be hired as civilians with the expectation of completing their military service requirements.  Kelly is completing her requirements by working for the Navy Reserve. Kelly has traveled all over the world on various ships.  Before she even finished college she was onboard US Naval Ship LARAMIE during the time the United Nations decided to go into Kosovo.  LARAMIE was a Navy support ship that replenished the battle ships with fuel, food, and other consumables.  She mentioned these ships are the only military ships that will employ civilians and they follow the battle fleet for the sole purpose of providing support and supplies to the vessels.

While onboard Kelly was getting hands-on training as an engineer.  Students at Kings Point are required to have at least one year of hands-on training on a ship before graduating. While she was getting her training she was traveling to Japan, Australia, Spain, Alaska, Hawaii…and plenty of other places (I just can’t remember them all…there were so many).

Now Kelly is an employee of the Maritime Engineers Beneficiary Association, which is the largest maritime union for engineers.  She was originally placed on NOAA ship RAINIER to work for 45 days beginning in April 2006, but after arrival, due to her level of experience as an engineer she was offered to stay onboard until August 2006.

I was just so impressed talking with Kelly.  She’s traveled all over the world working as an engineer on many different kinds of ships.  I really appreciated the time she took to explain how all the machines work to power the RAINIER!!  She is obviously doing what she enjoys and life at sea comes very natural to her.  After talking with Kelly, I spent some time responding to e-mails and chatting with the crew. Today is Friday, so in my normal routine that means…DAYS OFF!!!  Not for the crew of RAINIER…their schedule continues to rotate regardless of what day of the week it is. Ordinary Seaman (OS) Megan Guberski put it simply, saying “yeah, every day is a Tuesday.” They are working so hard out here…all the time.  I think when we come into port I’ll get to see what it’s like for the crew to get a break.  That’ll be nice.

OS Megan Guberski showed me a little bit of what it’s like to work on maintaining the quality of the ship. She spends her days cleaning, painting, scraping, scrubbing, fixing, etc and gets to use really cool power tools (she mentioned that’s why she enjoys her job so much).  When she had a little time, I asked Megan if she would put on her fire suit for a picture, or as it is supposed to be called, “turnout gear.” Turnout gear is the protective gear Megan has to wear to fight a fire onboard.

She went through Coast Guard Advanced Fire Fighting Training and is now one of five people responsible for putting out a fire onboard! I noticed the suit during our fire drill earlier in the week and I SO badly wanted to get pictures, but knew it probably wasn’t the best time.  I was still trying to figure out where I was supposed to go in case of a fire. As I mentioned earlier…I get lost easily so stopping for photos during a fire drill would be a bad idea.

Anyway, it’s supposed to take them around a minute to get the suit on.  That seems impossible to me because there are a lot of things Megan had to put on. The turnout gear was even more difficult to get into than the Gumby suit and that took some serious effort.

Megan, as well as all the crew on the RAINIER, has been excellent at taking time to explain how things work on the ship. She has been on the RAINIER for about a year and a half now and is working her way up to be an AB, Able-Bodied Seamen.  By September 3rd of this year she will have enough days at sea to qualify as an AB onboard. Megan is very ambitious and has already completed all the training necessary to qualify as an AB.  She will need to take a Coast Guard test before she will earn the title, but she said she’s not concerned about that. It’s just a matter of getting in her sea time.

It’s been so nice to have the opportunity to learn about the different job opportunities onboard a NOAA ship. Many of the positions require little to no training prior to employment and therefore training is provided onboard the vessel.  I think that’s awesome!

Tonight I had halibut for dinner. The CO caught a 15-lb halibut off the stern of the ship and we all were able to enjoy!  There are hot springs on shore and rumor has it we’ll be visiting them soon. I’m looking forward to that.

I’m getting more used to the noises of the ship and am sleeping soundly.  My bunk is surprisingly cushy and very comfortable.  It wasn’t exactly easy getting out of it this morning.

I saw a sea otter today!!!  He was swimming on his back. We don’t have otters in Hawaii so I’m having my first otter encounters here in Alaska.  I guess some of the crew saw whales this morning as well, but I missed it!

Life is good out here on the RAINIER!  A little rainy today, but good!

This is cool…check it out!

Science and Technology Log 

This morning the RAINIER changed locations from Kanga Bay to Hot Springs Bay. I had an opportunity to go down in the Central Engine Room Control (CERC) and see how the engines are fired up to get the ship moving again.  Kelly Baughman, the ship’s Third Assistant Engineer (3AE), took some time to explain what I was observing down there before she got the engines going. Being in the engine room was really cool.  I was completely surrounded by buttons to push and knobs to turn and although very tempting, I didn’t touch any of them. The RAINIER has two main engines to motor her, one on the port (left) side of the ship and one on the starboard (right) side of the ship.  There are two generators that put out a total of 400 kilowatts of electrical power to the ship.  An additional smaller emergency generator is also a part of the ship, but it puts out significantly less energy than the two main generators.

On the bridge, Vessel Assistant, Kelson Baird is logging the ships position from four points on the radar screen.  The position of the points is recorded every half hour to monitor the effectiveness of the anchor.

Kelly also explained how the bow thruster works on the ship.  It basically looks like a fan and helps to maneuver the ship from the bow.  There are several other things that are monitored at the center console, but we weren’t able to get to all of them.  Kelly said tomorrow morning will be a better time to go over some of the other things in the engine room since we’ll be anchored in the bay. After visiting with Kelly, I had a nice afternoon talking with crew and soaking up ship life. I made my way up to the bridge where General Vessel Assistant (GVA) Kelson Baird was monitoring weather data. He was excellent at explaining all the different instruments used in collecting weather data onboard the ship. Every hour, on the hour, Kelson recorded weather information.  He started by logging the ship’s position (latitude/longitude).  Next he recorded an overall weather condition such as cloudy, rainy, drizzle etc. Today was cloudy and rainy. Kelson then stepped outside the bridge and looked to see what point of land was the furthest he could clearly see from the ship.  Once he found his point of land he came back inside the bridge and used the radar screen to determine a distance in nautical miles that point of land was from the ship.  This gave Kelson a visibility reading. Other information Kelson recorded was wind speed in knots, using the ship’s anemometer, as well as wind direction.  Wind direction (measuring from the direction the wind is coming from) can be measured using a gyrocompass, which is an electronic compass measuring to true north.

If the ship were underway he would have also had to record wave height, swell wave height, and sea wave height. Kelson said this would be done by a very scientific method called “eye balling it”…or as I like to say, EBI. Another measurement taken while at anchor was water temperature, which, by the way, was 49° F while I was in the bridge this afternoon.  Just as a quick side note: crew of the RAINIER surf in this water and are very excited to surf in the break off of Kodiak Island when we arrive in port.  I think they are crazy, but I’d love to watch them! The last weather measurements Kelson recorded were air temperature and atmospheric pressure. Two air temperature measurements are taken: one from what is called a wet bulb and one from a dry bulb.  Then he recorded sea level (atmospheric) pressure measured by a barometer.

Kelson went on to explain about “Big Weather”, which is an ongoing data collection project where weather information is sent every six hours via satellite to be used by NOAA’s National Weather Service.  Pretty amazing all the work that is being done on the RAINIER!

Personal Log 

I am seriously impressed by how well I am being fed on the ship.  Each meal I have several hot meal options to choose from and there is always a vegetarian option for those who do not eat meat.  The soup has been excellent!  There’s a full salad bar directly next to a freezer fully stocked with Haagen-Dazs ice cream!  I think that’s pretty good.  Coffee is available all day long as well which makes me very, very happy.  I won’t indulge on hydrographic survey days. We’ve already talked about that…

Calling All Middle Schoolers–We Need Help Answering a Few Questions! 

Third Assistant Engineer Kelly Baughman explained to me today that the ship can carry up to 16,800 gallons of freshwater. She went on to say that on average the ship’s crew uses anywhere between 1,500-2,000 gallons per day.

If the RAINIER were to be at sea for 21 days without coming into port to replenish its fresh water supply, how many days would it take for the ship to run out of fresh water?

How would the ship be able to produce more fresh water without having to go into port?

Science, Technology and a Little History…Log 

I am very proud to say I was onboard RAINIER (the world’s most productive coastal hydrographic survey ship), as well as a part of an eleven hour day of surveying, on the first annual World Hydrography Day! Yep, that’s right.  According to a message sent by NOAA Administrator Conrad C. Lautenbacher, Jr., (a retired Vice Admiral in the U.S. Navy), the United Nations General Assembly adopted Resolution A/60/30 in November of 2005 to acknowledge the International Hydrographic Organization’s role in advancing global navigation safety and protection to those at sea, making today World Hydrography Day!

I like the way Commander Guy Noll put it:  “We hit rocks so that you don’t have to”.  That gave me a new found appreciation for the work the crew is doing on the RAINIER.  I must admit this was not exactly a reassuring thought just before I was heading out for a full day of hydrographic surveying. But hey, it’s World Hydrography Day…I needed to celebrate appropriately.

I didn’t realize the real history and purpose of hydrography until talking with Ensign Sam Greenaway and Junior Survey Technician Tonya Watson on the survey launch today.  Hydrographic surveying in the United States actually dates back to 1807 when Thomas Jefferson established the “Survey of the Coast” to produce nautical charts for US coastal waters. The Survey of the Coast evolved in the current NOAA Office of Coast Survey (OCS). OCS is the oldest scientific agency in the federal government, and was established primarily to encourage commerce.  Jefferson was looking to support a growing economy in a safe and efficient manner.

According to Peter J. Guthorn, author of United States Coastal Charts. 1783-1861, the production and distribution of charts was delayed until 1843, with the first publication of the New York Harbor chart. This was due to the War of 1812, political disagreements (imagine that) and a lack of trained hydrographers.  Before the publication of government charts, there were private publications adapted from British and French charts with updates from local shipmasters and pilots familiar with the coasts of North America.

Check out NOAA’s link for more information on the work NOAA is doing. I find the history very interesting.  It’s really given me a sense of the global importance of the surveys conducted and the charts being produced.  I’m excited to be a part of it for these two weeks.  It’s only taken 200 years to come up with World Hydrography Day. I think the recognition is very well deserved and obviously overdue!

As for my time spent on the launch today:  Well, we left at 8:00 in the morning.  Within minutes the survey team onboard, ENS Sam Greenaway and JST Tonya Watson, were getting to work.  The first thing they did was use the Conductivity, Temperature and Depth instrument to determine the variation of temperature, salinity, and density in the water.  This helps determine the speed and path of the sonar energy through the water. A CTD measurement is taken once every four hours for each survey period.

After the CTD measurements were taken, they began running lines and logging sonar data. Today we were focusing on holiday lines. Holiday lines are basically holes in the data or areas where previous surveys may have missed collecting information.  From my understanding, there is a sonar transducer on the bottom of the survey boat. The Reson 8125 that I mentioned in my previous log (remember 120° of coverage using 240 individual beams) is mounted on survey boat RA4. RA4 is the launch I was on today (World Hydrography Day).

While the boat is moving at a speed of no greater than 8 knots along the charted line, this transducer is sending out multi-beam sonar to the ocean floor.  Steering the launch to remain on the line is not easy. Deck Utilityman (DU) Ken Keys, the coxswain of the boat for today, let me give it a shot.  I was steering more on a zigzagged line rather than a straight one. It was actually kind of stressful because the accuracy of the sonar data is affected by how well the person steering stays on the line.

While cruising down the line, data is continuously collected on the amount of time it takes the sonar to echo back from the ocean floor to the transducer.  I was able to view rocks on the ocean floor from the display on the computer screen.  As you can imagine, in shallower water this information came in handy to the driver of the boat, which ultimately was helpful to all of us onboard •

Personal Log 

I am having an incredible time on the RAINIER! Last night I was able to go for a run on the treadmill they have onboard.  I along with Survey Technician, Erin Campbell decided to call the workout area Club RAINIER.  It basically consists of three machines, a rowing machine and free weights, down in what looks to me like a storage space.  I was very excited to hear about the equipment onboard!  I think it’s impressive they have it available.

Something interesting that is NOT available to the RAINIER crew is a bathroom on the survey launch boats. Hmmm?  Needless to say, on days I am out on a launch I’m taking it really easy on the coffee and any other beverages throughout the survey.

Calling All Middle Schoolers-We Need Help Answering a Few Questions! 

These questions come from one of the Junior Survey Technicians onboard the RAINIER, Tanya Watson.

What do you suppose the effect of high frequency sonar, such as the sonar NOAA uses in their hydrography surveys, has on the marine mammals living in the sea?  Do you suspect there to be a difference between the effects of low frequency sonar vs. high frequency sonar?  Let me know what you think!

Science and Technology Log 

Today I awoke for my first day in Kanga Bay. The bay was absolutely beautiful this morning, looking perfectly still and glassy. The Captain, CDR Guy Noll, said it’s not normally this clear.  I was absolutely awe-struck by the scenery!  The first thing I did was head to the fantail for muster with the crew involved in launching the hydrographic survey boats off the ship.  The fantail is the area outside in the very back of the ship. Muster was led by the Captain and FOO, Field Operations Officer. They informed the crew of potential weather changes for the day’s mission that may affect the survey boats.  It was incredible to watch the boats being launched from the ship.  A large crane lifted each boat up and over the side of the ship and into the ocean.  After the survey boats were launched two additional skiffs were launched as rescue boats, in case of an emergency.  The first skiff lowered weighs up to 3,000 lbs, with the second skiff lowered, weighing 2,400 lbs. The Captain said the rescue skiff can travel up to a speed of 45 knots (nautical mile/hour).

The 3,000lb skiff is being lifted up and over one of the survey boats off of NOAA ship RAINIER.  The skiff will serve as a rescue boat in case of an emergency while the survey boats are collecting data near the bay.

Today survey boats RA4 and RA5 were launched from the ship.  RA stands for the RAINIER. Ben, the ships FOO, explained to me the difference between the two survey boats being launched. RA4 is a Reson 8125. It uses a multi-beam sonar system that covers an area of 120° using 240 individual beams to collect sonar data.  This gives the RA4 the ability to collect very high resolution data.  RA5 is a Reson 8101, and is more of an all purpose survey boat Ben mentioned.  He said this boat does not have the high resolution capabilities that the RA4 has because it has around 150° of coverage using only 101 individual beams to collect sonar data.  Tomorrow I will be going out on a survey and will have a much better understanding of how the data is actually collected and processed. While the survey boats were out today, I was spending my time on the NOAA ship getting administrative things taken care of. Once most of that was finished I made my way to the bridge to ask a few questions about the navigating process. Olivia, the Officer on Duty, or OOD was very helpful in answering some of my questions and then once she needed to leave the bridge, Jonathon one of the ship’s Abs, explained how to get a radar fix.

As I mentioned in my last log, the ship’s course is already plotted prior to departure by the Navigation Officer. He plotted the course on a chart of the Sitka area on down to the Islet Passage and Kanga Bay where the ship is anchored now. Jonathon was on the bridge today collecting radar data to be sure the ship wasn’t shifting too much, constantly confirming that the anchor is effectively keeping the ship in place.  A reading is taken every 30 minutes.  You would never know it while being on board, or at least I didn’t notice, but the ship had rotated 300° on the anchor and then swung back again.

Jonathon showed me how to get what you call a radar fix.  A radar fix is basically used to find the exact position of the ship. I observed Olivia, one of the officers doing this in the bridge while we were underway yesterday. Although the officers do their best to remain on the plotted course line, there are other factors that will cause the boat to get off the line. Current is one of them. Readings of three points of land, the bearing as well as the range, are taken from the radar screen.  Points of land are simply points from the land that are distinctive enough to use to plot the position of the ship using the chart.  Once the three points are taken with the bearings (angle to the point) and range (distance to the point) recorded, they are brought over to the chart where a tool called a divider is used so plot the three angles. The point at which those three angles intersect is the exact position of the ship. This can then be compared to the line already plotted to mark the ship’s course.  The crew will then have an idea of the ships cross track error.  Cross track error is how far the ship is off the plotted course line.  Whew.

Personal Log 

I have been asking a million questions, picking the brains of the crew. Everyone has been so giving of their time to explain things to me on the ship! Things can be complicated on the RAINIER.  There is just so much to learn!!  Something that was particularly fun about today was the abandon ship drill. This was only something I would consider fun because I got to put on my immersion suit (or Gumby suit, as I heard it called today).  The immersion suit would be used to keep warm in the water if we all needed to abandon ship.  I had fun trying it on. The XO had to help me get it on; these things are not that easy to get into.  I tried really hard to make the gloves of the suit shake for a picture, but it wasn’t easy!  I grabbed extra blankets for a warmer nights sleep tonight.  The ship can feel drafty in my stateroom.  I’m looking forward to a long day of surveying!!! I’m so excited to share!

Calling All Middle Schoolers–We Need Help Answering a Few Questions! 

These questions come straight from the RAINIER’s Captain:

What is a nautical mile?  How is it different from a mile on land? How would I convert a nautical mile into miles/hour?

Science and Technology Log 

Yesterday I was invited out on a boat launch with LTJG Abigail Higgins, Junior Survey Tech Tonya Watson, and Deck Utility Man Kenneth Keys.  We were sent out to set a couple of buoys to mark locations where divers from the RAINIER could go down later in the day and take a closer look at some peculiar features from the sonar soundings.  We also had to run a couple of survey lines around an object near Petersburg Harbor on something peculiar Captain Guy Noll had spotted in the sonar record.  I was able to pilot the launch for part of the trip and DU Keys gave me a quick course on navigation around marked points in the Wrangell Narrows.  This was really cool!  LTJG Higgins showed me how the boat collects data to take back to the RAINIER where it is processed to be used on navigation charts.

When on a boat launch you may have to take lunch with you because you will not be back to the RAINIER in time for lunch. The skies were clear and full of intense Alaskan sunshine, which makes it feel warmer than the actual temperature outside. It was a beautiful day enjoyed even the more by having lunch on the boat. When the launch boat returns to the RAINIER the data is downloaded to the ships computers where it is processed so that charts and graphs can be made or updated. Below physical scientist Shyla Allen from the Pacific Hydrographic Branch assist ENS Laurel Jennings in making plans for running lines at the next stop near Sitka. ENS Jennings is in her first year on the RAINIER and a part of the NOAA officer corps aboard the RAINIER.

Personal Log 

Today was an absolutely beautiful day in SE Alaska.  I really enjoyed working with the survey technicians and people aboard the RAINIER.  I have learned much more than I thought ever existed when comes to navigating the waters, coastlines, and harbors of Alaska. Today we are traveling to Biorka Island, which is northwest of where we were the previous week.

Questions of the Day 

When approaching a green buoy from sea in a channel in North America which side should your boat approach on?

When approaching a red buoy from sea in a channel in North America which side should your boat approach on?

Assignment 

Plot a course if you were the pilot of the RAINIER that you would follow from Wrangell Narrows near Petersburg to Biorka Island.

Science and Technology Log 

Early this morning at 4:35 am, RAINIER and her crew got underway for Valdez.  My twelve days aboard the ship have gone by quickly, and I am excited about all the experiences I will have to take back to my students.  The photo below depicts one of my favorite parts of the hydrographic mission:  taking launches out into the sound to survey the seafloor. During these workdays, the crewmembers took the time to train me on how the ELAC and RESON sonar work. I was able to actually participate in all of the ship’s data collection and operations. One of the most interesting software programs I had the opportunity to use was the HYPAC program that helps guide the coxswain of the boat.  The technology and equipment are key elements in the current data collection and analysis surrounding hydrography.

During informal interviews with crewmembers, I learned a great deal about the logistics and planning of a two-week survey such as this one.  Most of the crew resides in or around Seattle where the ship will remain during the winter.  During this time, officers will write their reports on the survey, data will be pr
