Science and Technology Log

You may be wondering what role technology plays in a hydrographic survey.  I have already written about how modern survey operations rely on the use of multibeam sonar.  What I have not described, and am still coming to understand myself, is how complex the processing of sonar data is, involving different types of hardware and software.  

For example, when the sonar transducer sends out a pulse, most of the sound leaves and eventually comes back to the boat at an angle.  When sound or light waves move at an angle from one substance into another, or through a substance with varying density, they bend. You have probably observed this before and not realized it.  A plastic drinking straw in a glass of water will appear broken through the glass. That is because the light waves traveling from the straw to your eye bend as they travel.

Refraction in a glass of water

The bending of a wave is called refraction. Sound waves refract, too, and this refraction can cause some issues with our survey data. Thanks to technology, there are ways to solve this problem. The sonar itself uses the sound velocity profile from our CTD casts in real time to adjust the data as we collect it. Later on during post processing, some of the data may need to be corrected again, using the CTD cast profiles most appropriate for that area at that general time. Corrections that would be difficult and time-consuming if done by hand are simplified with the use of technology.

Another interesting project in which I’ve been privileged to participate this week was setting up a base station at Shark Point in Ugak Bay.  You have most likely heard of the Global Positioning System, and you may know that GPS works by identifying your location on Earth’s surface relative to the known locations of satellites in orbit.  (For a great, kid-friendly explanation of GPS, I encourage students to check out this website.)  But what happens if the satellites aren’t quite where we think they are?  That’s where a base station, or ground station, becomes useful. Base stations, like the temporary one that we installed at Shark Point, are designed to improve the precision of positioning data, including the data used in the ship’s daily survey operations.

Setting up the power source for the base station

Setting up the Base Station involved several steps.  First, a crew of six people were carried on RA-7, the ship’s small skiff, to the safest sandy area near Shark Point. It was a wet and windy trip over on the boat, but that was only the beginning! Then, we carried the gear we needed, including two tripods, two antennae (one FreeWave antenna to connect with the ship and a Trimble GPS antenna), a few flexible solar panels, two car batteries, a computer, and tools, through the brush and brambles and up as close to the benchmark as we could reasonably get.  A benchmark is a physical marker (in this case, a small bronze disk) installed in a location with a known elevation above mean sea level. For more information about the different kinds of survey markers, click here.

Next we laid out a tarp, set up the antennae on their tripods, and hooked them up to their temporary power source.  After ensuring that both antennae could communicate, one with the ship and the other with the satellites, we met back up with the boat to return to the ship.  The base station that we set up will be retrieved in about a week, once it has served its purpose.

Meet Ben Evans.  As the Commanding Officer of NOAA Ship Rainier, he is the leader, responsible for everything that takes place on board the ship as well as on the survey launches. Evans’ first responsibility is to the safety of the ship and its crew, ensuring that people are taking the appropriate steps to reduce the risks associated with working at sea.  He also spends a good deal of his time teaching younger members of the crew, strategizing with the other officers the technical details of the mission, and interpreting survey data for presentation to the regional office.

Evans grew up in upstate New York on Lake Ontario.  He knew that he wanted to work with water, but was unsure of what direction that might take him.  At Williams College he majored in Physics and then continued his education at Woods Hole Oceanographic Institution, completing their 3-year Engineering Degree Program.  While at WHOI, he learned about the NOAA Commissioned Officers Corps, and decided to apply.  After four months of training, he received his first assignment as a Junior Officer aboard NOAA Ship Rude surveying the waters of the Northeast and Mid-Atlantic.  Nearly two decades later, he is the Commanding Officer of his own ship in the fleet.

When asked what his favorite part of the job is, Evans smiled to himself and took a moment to reply.  He then described the fulfillment that comes with knowing that he is a small piece of an extensive, ongoing project–a hydrographic tradition that began back in 1807 with the United States Survey of the Coast.  He enjoys working with the young crew members of the ship, sharing in their successes and watching them grow so that together they may carry that tradition on into the future.

Personal Log

For my last post, I would like to talk about some of the amazing marine life that I have seen on this trip.  Seals, sea lions, and sea otters have shown themselves, sometimes in surprising places like the shipyard back in Seward.  Humpback whales escorted us almost daily on the way to and from our small boat survey near Ugak Bay. One day, bald eagles held a meeting on the beach of Ugak Island, four of them standing in a circle on the sand, as two others flew overhead, perhaps flying out for coffee.  Even the kelp, as dull as it might seem to some of my readers, undulated mysteriously at the surface of the water, reminding me of alien trees in a science fiction story.

Shark Point

Stepping up onto dry land beneath Shark Point, we were dreading (yet also hoping for) an encounter with the great Kodiak brown bear. Instead of bears, we saw a surprising number of spring flowers, dotting the slopes in clumps of blue, purple, and pink. I am sensitive to the smells of a new place, and the heady aroma of green things mixed with the salty ocean spray made our cold, wet trek a pleasure for me.

Science and Technology Log

For my second time out on a launch, I was assigned to a shoreline survey at Narrow Cape and around Ugak Island (see chart here).  Survey Tech Audrey Jerauld explained the logistics of the shoreline survey.  First, they try to confirm the presence of charted features (rocks) along the shore. (As you may remember from my last post, a rock is symbolized by an asterisk on the charts.) Then, they use the small boat’s lidar (LIght Detection And Ranging) to find the height of the rocks. Instead of using sound pulses, as with sonar, lidar uses pulses of laser light.  

Point Cloud
Point Cloud: Each dot represents a lidar “ping”, indicating the presence of features above the waterline

Once a rock was identified, Audrey photographed it and used the laser to find the height of the rock to add to the digital chart.  The launch we used for the shoreline survey was RA-2, a jet boat with a shallow draft that allows better access to the shoreline. We still had to be careful not to get too close to the rocks (or to the breakers crashing into the rocks) at certain points around Ugak Island.  The line parallel to the shore beyond which it is considered unsafe to survey is called the NALL (Navigable Area Limit Line). The NALL is determined by the crew, with many factors taken into account, such as shoreline features, marine organisms, and weather conditions.  An area with many rocks or a dangerously rocky ledge might be designated as “foul” on the charts.

Amanda and Audrey

I must pause here to emphasize how seriously everyone’s safety is taken, both on the small boats and the ship itself.  In addition to strict adherence to rules about the use of hard hats and Personal Flotation Devices in and around the launches, I have participated in several drills during my stay on the ship (Man Overboard, Fire and Emergency, and Abandon Ship), during which I was given specific roles and locations.  At the bottom of each printed Plan of the Day there is always a line that states, “NEVER shall the safety of life or property be compromised for data acquisition.” Once more, I appreciate how NOAA prioritizes the wellbeing of the people working here. It reminds me of my school district’s position about ensuring the safety of our students.  No institution can function properly where safety is not a fundamental concern.


Career Focus – Marine Engineer

Johnny Brewer joined the Navy in 1997.  A native of Houston, Texas, many of his family members had served in the military, so it seemed natural for him to choose a similar path after high school.  The Navy trained him as a marine engineer for a boiler ship. Nearly 15 years later he went into the Navy Reserve and transitioned to working for NOAA.

Working as an engineer requires mental and physical strength.  The Engineering Department is responsible for maintaining and updating all of the many working parts of the ship–not just the engine, as you might think! The engineers are in charge of the complex electrical systems, plumbing, heating and cooling, potable water, sewage, and the launches used for daily survey operations.  They fix everything that needs to be fixed, no matter how large or small the problem may be.

Johnny emphasized how important math is in his job.  Engineers must have a deep understanding of geometry (calculating area, volume, density, etc.) and be able to convert measurements between the metric and American systems, since the ship’s elements are from different parts of the world.  He also described how his job has given him opportunities to visit and even live in new places, such as Hawaii and Japan. Johnny said that when you stay in one place for too long you can become “stuck in a box,” unaware of the world of options waiting for you outside of the box.  As a teacher, I hope that my students take this message to heart.


Personal Log

In my last post I introduced Kimrie Zentmeyer, our Acting Chief Steward. In our conversation, she compared the ship to a house, the walls of which you cannot leave or communicate beyond, except by the ship’s restricted wi-fi, while you are underway.  I would like for my readers (especially my students) to imagine living like this, confined day in and day out to a single space, together with your work colleagues, without family or friends from home.  How would you adjust to this lifestyle? Do you have what it takes to live and work on a ship? Before you answer, consider the views from your back porch!

Q & A

Are there other NOAA ships working in Alaska?

Yes!  NOAA Ship Fairweather is Rainier’s sister-ship and is homeported in Ketchikan, Alaska.  Also, the fisheries survey vessel, NOAA Ship Oscar Dyson is homeported in Kodiak, not far from where we are currently located.

What did you eat for dinner?

This evening I had sauteed scallops, steamed broccoli, and vegetable beef stew. And lemon meringue pie. And a cherry turnover. And ice cream.

Let’s talk charts.  A chart is a map that shows specific details of the shoreline and the seafloor, including depth (usually in fathoms) and notable features.  Click here to view the chart of the area, “Chiniak Bay to Dangerous Cape.”  Can you find Saltery Cove, where we are currently anchored? How about Cape Greville and Sequel Point?  The latter are located at the northern and southern ends of the area that we surveyed with the launch last Wednesday afternoon.

If you look carefully, you will see many symbols along the shoreline.  An asterisk represents a rock awash that may only be visible when the water recedes at low tide.  A series of dots represents sandy shore, while small scallop shapes and circles denote breakers and stones, respectively.  The small, filled in triangles on land show where there are cliffs or steep slopes. The symbol that looks like a stick with small branches represents kelp.  Kelp is considered a possible hazard, since it can get wrapped around the propeller of a boat.

Now move your gaze to the ocean.  The numbers that you see are depth soundings, measured in fathoms.  Recall that one fathom equals 6 feet. This means that where you see a sounding of 9 fathoms, the water is actually 54 feet deep (relative to the mean lower low water datum).  If you are looking at the area near Cape Greville, all of the soundings that you see on the chart were taken between 1900 and 1939, before the invention of multibeam sonar. There was a magnitude 9.2 earthquake on March 27, 1964 that changed the depths and shapes of the landforms.  Finally, you should not discount the effects of weathering and erosion by wave action on this area.  The dynamic nature of it all makes the work that NOAA is doing all the more important for the safety of anyone at sea.

Career Focus – Steward

With so many people and so much work being done every day, how do you ensure good morale among the crew? You make sure that they are well fed!  That’s where the Stewards Department comes in to play. I met with Kimrie Zentmeyer, Acting Chief Steward, to learn how she and her staff take care of all of the people on the ship.

The Stewards Department is like a sweet grandmother, spoiling her grandbabies by providing good food and other comforts to the entire Rainier family.  Stewards plan and prepare the meals, supply appropriate linens and bedding, and maintain a positive, upbeat attitude in the face of a potentially stressful work environment. Stewards work long hours in close quarters and, as Kimrie says, provide the “customer service” of the ship. Kimrie herself has worked on ships for many years.  She started out as a mess person for Chevron Shipping when her daughter left home for college. As part of the NOAA Relief Pool, Kimrie has worked on ten of NOAA’s ships, filling positions on a temporary basis until permanent employees can be found. It is clear that she has a deep understanding of the emotional needs of a ship’s crew, and she enjoys the camaraderie and cooperation that develop in this unique work environment.

Personal Log

I would like to take some time to write about the ship. Rainier is a hydrographic survey vessel. (For more information about what that means, see my last post!)  Constructed in Jacksonville Florida, and then later commissioned in 1968, Rainier is one of the longest-serving ships in NOAA’s fleet.  It is named after Mount Rainier, a volcanic mountain in western Washington state.  Students might remember that this mountain is located near a continent-ocean convergent plate boundary between the North American and Juan de Fuca plates, where subduction has lead to the formation of the Cascade Volcanic Arc. Our ship’s home port is located in Newport, Oregon. Originally, however, the home port was in Seattle, Washington, and so it was christened after the iconic Mount Rainier.

NOAA Ship Rainier is 231 feet long from bow to stern.  There are six different levels, or decks, identified by the letters A-F moving upwards from the bottom of the ship.  Each deck is broken into numbered sections, or rooms.

To communicate a particular location, you might refer to the deck letter and section number.  You might also use the following vocabulary:

Port – the left side of the ship

Starboard – the right side of the ship

Fore – forward of the beam

Aft – behind the beam

Stern – the back end of the ship

Bow – the front end of the ship

D-Deck

Overhead diagram of the “D” Deck

My room is located on the E deck, one level below the bridge.  On the D deck we enjoy delicious, cafeteria-style meals in the mess, and we can work, read, relax, or watch movies in the lounge.  The steering takes place on the Bridge, the command center of the ship. I will highlight the bridge in a future post. Other common areas include the Plotting Room, the Holodeck, the Boat Deck, Flying Deck, and Fantail.  There is also a laundry room and even a gym! Although it can be a bit confusing at first, the ship’s layout makes sense and allows for efficiency without sacrificing the crew’s comfort.

Lona on launch RA-5
Yours truly, happy on RA-5

Today I went out on a launch for the first time.  The plan was to survey an area offshore and then move nearshore at low tide, with the water at its lowest level on the beach of Kodiak Island.  Survey Techs, Carl Stedman and Christina Brooks, showed me the software applications used to communicate with the coxswain and collect data. To choose the best frequency for our multibeam pulse, we needed to know the approximate depth of the area being surveyed.  If the water is deeper, you must use lower frequency sound waves, since higher frequency waves tend to attenuate, or weaken, as they travel. We chose a frequency of 300 kilohertz for a 60 meter depth. Periodically, the survey techs must cast a probe into the water.  The Sea-bird SeaCAT CTD (Conductivity, Temperature, Depth) measures the characteristics of the water, creating a sound velocity profile. This profile can tell us how quickly we should expect sound waves to travel through the water based upon the water’s temperature, salinity, and pressure.

Using the sound velocity profile allows the computer’s Seafloor Information System (SIS) to correct for changes in water density as data is being collected.  Once the profile was transmitted to SIS, we were ready to begin logging data.

Imagine that you are mowing your lawn.  To maximize efficiency you most likely will choose to mow back and forth in relatively straight paths, overlapping each new row with the previous row.  This is similar to how the offshore survey is carried out. As the boat travels at a speed of about 7 knots, the Kongsberg EM2040 multibeam sonar transducer sends out and receives pulses, which together create a swath.  The more shallow the water, the wider the base of the swath.

After lunch we changed to a nearshore area closer to Kodiak Island between Sequel Point and Cape Greville. It was important to wait for low tide before approaching the shore to avoid being stuck inshore as the tide is going out.  Even so, our coxswain was very careful to follow the edges of the last swaths logged. Since the swath area extends beyond the port and starboard sides of the boat, we could collect data from previously uncharted areas without driving directly above them.  In this way we found many rocks, invisible to the naked eye, that could have seriously damaged an unlucky fisherman!


Career Focus – Able Seaman

Our coxswain driving the boat today was Allan Quintana.

As an Able Seaman, Allan is part of the Deck Department, which functions primarily to keep track of the ship, manage the lines and anchoring, and deploy and drive the launches.  Allan started out working for the Navy and later transitioned to NOAA. A Miami native, he told me how he loves working at sea, in spite of the long stretches of time away from his friends and family back home.


Personal Log

If you have never been on a boat before, it is a unique experience. Attempts have been made by poets, explorers, scientists, naturalists, and others throughout history to capture the feeling of being at sea.  Although I’ve read many of their descriptions and tried to imagine myself in their shoes, nothing compares to experiencing it first-hand.

Standing on the bow of the anchored ship, looking out at the water, my body leaning to and fro, rising and falling, I am a sentient fishing bobber, continuously rocking but not really going anywhere.  My head feels somehow both heavy and light, and if I stand there long enough, I just might fall asleep under the spell of kinetic hypnosis. The motion of the launch is different. A smaller boat with far less mass is bullied by the swells. For a new crew member like me, it’s easy to be caught off guard and knocked over, unless you have a good grip. I stand alert, feet apart, one hand clasping a rail, as the more experienced crew move about, casually completing various tasks. I wonder how long it would take to become accustomed to the boat’s rising and falling.  Would my body gradually learn to anticipate the back and forth rocking? Would I eventually not feel any movement at all?

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!

Finishing off the school year has never been so exciting as it is now, with an Alaskan adventure awaiting me!  My students are nearly as giddy as I am, and it is a pleasure to be able to share the experience with them through this blog.

In two weeks, I will leave my home in the Appalachian foothills of Georgia and fly to Anchorage, Alaska.  From there I will take a train to the port city of Seward, where I will board NOAA Ship Rainier.  For 11 days we will travel around Kodiak Island conducting a hydrographic survey, mapping the shape of the seafloor and coastline. The Alaska Hydrographic Survey Project is critical to those who live and work there, since it greatly improves the accuracy of maritime navigational charts, ensuring safer travel by sea.

Kodiak Island is the largest island in Alaska and the second largest in the United States.  It is located near the eastern end of the Aleutian Trench, where the Pacific Plate is gradually being subducted underneath the North American Plate.
