Personal Log – An Introduction

Hello!  My name is Staci DeSchryver and I will be traveling this upcoming July on the Oscar Elton Sette as part of the HICEAS program!

I am an Oceanography, Meteorology, and Earth Science teacher at Cherokee Trail High School in Aurora, CO.  This August will kick off my 14th (yikes!) year teaching.  I know you might be thinking, “Why Oceanography in a landlocked state?”  Well, the reason why I can and do teach Oceanography is because of Teacher At Sea.  I am an alumna, so this is my second official voyage through the Teacher At Sea program.  It was all of the wonderful people I met, lessons I learned, and science that I participated in on the

Oscar Dyson in 2011 that led me to encourage my school to put an Oceanography course in place for seniors as a capstone course.  This past year was the first year for the Oceanography and Meteorology courses, and they were very well received!  I have three sections of each class next year, as well!  (Shout out to all my recent senior grads reading this post! You were awesome!)  We study our World’s Ocean from the top of the water column all the way to the deepest parts of the Marianas Trench, and from the tiniest atom all the way up to the largest whale.  I  believe it is one of the most comprehensive courses offered to our students – incorporating geology, chemistry, physics, and biology, but then again, I’m a bit biased.

Apart from being a teacher, I am a wife to my husband of 8 years, Stephen.  We don’t have children, but we do have two hedgehogs, Tank and Willa, who keep us reasonably busy.  Willa only has one eye, and Tank is named Tank because he’s abnormally large for a hedgie.  They are the best lil’ hedgies we know.  We enjoy camping, rock climbing, and hiking – the typical Coloradans, though we are both originally from Michigan.  When we aren’t spending time together, I like to dance ballet, read, write, and I recently picked up a new weightlifting habit, which has led me to an entire new lifestyle of health and wellness with an occasional interjection of things like Ice Cream topped with caramel and Nachos when in the “off” season (hey, nobody’s perfect).

I will be leaving for Honolulu, Hawaii on July 4th to meet up with the fine scientists that make up the HICEAS team.  What is HICEAS?  Read below to find out more about HICEAS and the research we will be doing onboard!

Science Log

The HICEAS (Hawaiian Islands Cetacean and Ecosystem Assessment Survey) is a study of Cetaceans (Whales, Dolphins, and Porpoises) and their habitats.  Cetaceans live in the ocean, and are characterized by being carnivorous (we will get along just fine at the dinner table) and having fins (since I am a poor swimmer, I will humbly yield to what I can only assume is their instinctive expertise).  This means that the study will cover all manners of these majestic creatures – from whales that are definitely easily identifiable as whales to whales that look like dolphins but are actually whales to porpoises that really look like whales but are actually dolphins and dolphins that look like dolphins that are dolphins and…  are you exhausted yet?  Here’s some good news – porpoises aren’t very common in Hawaiian waters, so that takes some of the stress out of identifying one of those groups, though we will still be on the lookout.  Here’s where it gets tricky – it won’t be enough to just sight a whale, for example and say, “Hey! We have a whale!”  The observers will be identifying the actual species of the whale (or dolphin or possible-porpoise).  The observers who tackle this task are sharp and quick at what is truly a difficult and impressive skill.  I’m sure this will be immediately confirmed when they spot, identify, and carry on before I say, “Wait! Where do you see it?”

This is the research area for the HICEAS project. Map/photo is credited directly to the HICEAS website, https://www.pifsc.noaa.gov/hiceas/whats_hiceas.php

There are 25 cetacean species native to Hawaiian waters, so that’s a big order to fill for the observers.  And we will be out on the water until we locate every last one.  Just kidding.  But we will be looking to spot all of these species, and once found, we will do our best to estimate how many there are overall as a stock estimate.  Ideally, these cetacean species will be classified into three categories – delphinids (dolphins and a few dolphin-like whales), deep diving whales (whales with teeth), and baleen whales (of the “swim away!” variety).  Once identified in this broad sense, they will then be identified by species.  However, I do have a feeling these two categorizations happen all at once.

Once the data is collected, there is an equation that is used to project stock estimates for the whole of the Pacific.  More on this later, but I will just start by saying for all you math folk out there, it’s some seriously sophisticated data extrapolation.  It involves maths that I have yet to master, but I have a month to figure it out, so it’s not looking too bleak for me just yet.  In the meantime, I’m spending my time trying to figure out which cetaceans that look like dolphins are actually possible-porpoises, and which dolphins that look like dolphins are actually whales.

Goals and Objectives of the HICEAS

The HICEAS study operates as a part of the Pacific Islands Fisheries Science Center (PIFSC) and the Southwest Fisheries Science Center (SFSC), both under the NOAA umbrella.  Our chief scientist is Dr. Erin Oleson, who will be the lead on this leg of the cruise. HICEAS last collected data in 2010, and is now ready for the next round of stock assessments.  HICEAS is a 187-day study, of which we will be participating in approximately 30 of those days for this particular leg.  Our research area is 2.5 million square kilometers, and covers the whole of the Hawaiian Archipelago and it’s Exclusive Economic Zone, or EEZ!  The HICEAS study has three primary goals:

  1.  Estimate the number of cetaceans in Hawaii.
  2.  Examine their population structure.
  3.   Understand their habitat.

Studies like the HICEAS are pretty rare (2002, 2010, and now 2017), so the scientists are doing their best to work together to collect as much information as they possibly can during the study.  From what I can gather in lead-up chats with on board scientist Kym Yano, we will be traveling along lines called “transects” in the Pacific Ocean, looking for all the popular Cetacean hangouts.  When a cetacean is sighted, we move toward the lil’ guy (or gal) and all his friends to take an estimate, and if it permits, a biopsy.  There is a second team of scientists working below deck listening for Cetacean gossip (whale calls) as well.  Acoustic scientists will record the whale or dolphin calls for later review and confirmation of identification of species, and, of course, general awesomeness.

But that’s not all!

We will also be dropping CTD’s twice per day, which is pretty standard ocean scientific practice.  Recall that the CTD will give us an idea of temperature, salinity, and pressure variations with depth, alerting us to the presence and locations of any of the “clines” – thermocline, halocline, and pycnocline.  Recall that in areas near the equator, rapid changes of temperature, salinity, and density with depth are pretty common year-round, but at the middle latitudes, these form and dissipate through the course of the solar year. These density changes with depth can block nutrients from moving to the surface, which can act as a cutoff to primary production.  Further, the CTD readings will help the acoustic scientists to do their work, as salinity and temperature variations will change the speed of sound in water.

There will also be a team working to sight sea birds and other marine life that doesn’t fall under the cetacean study (think sea turtles and other fun marine life).  This study is enormous in scope.  And I’m so excited to be a part of it!

Pop Quiz:

What is the difference between a porpoise and a dolphin?  

It has to do with 3 identifiers:  Faces, Fins, and Figures.

According to NOAA’s Ocean Service Website…

Faces:  Dolphins have prominent “beaks” and cone-shaped teeth, while Porpoises have smaller mouths and teeth shaped like spades.

Fins: Dolphin’s dorsal (back) fins are curved, while porpoises fins are more triangle-shaped

Figures: Dolphins are leaner, and porpoises are more “portly.”

Dolphins are far more prevalent, and far more talkative.  But both species are wicked-smart, using sonar to communicate underwater.

Science and Technology Log

One of the lessons I want to take back to my students is not only a better understanding of some incredible career opportunities out there that they probably are not aware of, but also how some simple, almost by chance factors can influence our career choices.  For example, in speaking with PJ Klavon one of the ship’s Officers on Duty (OOD), I asked how he came about becoming a NOAA officer.  He said he was at a job fair and a NOAA staff member asked him if he would like to fish and captain a ship.  He answered “Yes” and here he is, having been part of the NOAA program the past 7 years.  I also met Sarah Donohoe, the ship’s navigator.  She commented that while in middle school she happened to read the hardcover book about being a Teacher at Sea that NOAA produced a few years ago.  It intrigued her then and now here she is, working her way up the chain of command having first earned a degree in Biology.

We headed out of the San Diego port on Monday, June 19 with the objective of traveling straight to Vancouver where we are to begin our main transects, collecting samples of fish throughout the night along a very specific path.  The transect lines have been used for several years so that the data will show how species and population sizes change over time.

Transect Lines are paths along which one counts and records occurrences of the species of study (e.g. sardines). It requires an observer to move along a fixed path, to count occurrences along the path and, at the same time (in some procedures), obtain the distance of the object from the path.  There will be more on this to follow when we get to actively fishing in a couple of days.

Consider the path on the diagram below (image from http://www.fao.org).

Samplings are taken at regular intervals.  The pathways are marked by longitude and latitude so they can be repeated as needed.

Since we are mostly just cruising to our starting point, there has not been much research going on.  The main activity has been to collect eggs from the water directly below the boat.  This water is channeled through a tube containing a mesh filter capable of capturing organisms and eggs that are 5 microns in diameter or larger.  There are two main egg types that the researchers are looking for – the eggs from anchovies and sardines.  They are monitoring how many they find in the samples being collected every 30 minutes.  This information can be compared to the water temperature, location of the vessel, and the size of schools of these organisms as observed via sonography.

CUFES  (Continuous underway fish egg sampler)  Approx. 640 L/min of water flows through the apparatus illustrated below.  The water flows through a tube that has the 5 micron mesh filter inside which collects the eggs, etc. found in that water sample. The sample is then rinsed into a petri dish, where the number of eggs of each species is identified and recorded.  The sample is then placed in a 5% formalin/salt water solution for preservation and later study.

CUFES (Continuous Underway Fish Egg Sampler)

The image below represents the eggs and multiple species of zooplankton that can be captured during one CUFES sample period.  The anchovy eggs are a very distinct oval shape.  See if you can find them in the sample below!

Personal Log

I arrived in San Diego last Sunday afternoon.  With the ship in port for the weekend, there were few staff on board so I had a quiet start to my trip. PJ Klavon, the Officer on Duty (OOD) did a fabulous job of keeping me company and patiently answered my questions about the ship, our itinerary, what a “typical day” looks like, and the various roles of the ship’s personnel.  As the evening progressed, I had a chance to meet a few other members of the crew.   It was great to have some time to take it all in, move into my stateroom, and even enjoy an off-ship dinner in town.  I watched the sunset in the harbor from the same deck level my room is located on.

Here’s me squinting into the morning sun for a selfie the morning of our launch.  My room is on the 0-1 level with a small window looking out the starboard side of the boat.

TAS Dawn White and NOAA Ship Reuben Lasker

I haven’t written much these first few days for two reasons: 1) there hasn’t been much activity to report on and 2) I have struggled to get my “sea legs” beneath me.  The weather north of us has not been cooperating very well and the wind/waves have been rather severe at times.  Yesterday winds blew constantly at about 30 knots with periods of time blowing 40-45 knots.  The waves were incredible.  Quite an experience attempting stairs in such conditions, or trying to fill your plate during lunchtime!  The ocean is much less angry today so I feel like I can look at a computer screen for any period of time.

I am staying up later this evening to begin the transition to our nighttime fishing schedule.  We will be trawling and working on evaluating our catch from about 8 p.m. to 8 a.m. starting Sunday night.  I am really looking forward to seeing what we catch!

Did You Know?

There are opportunities beyond the Teacher at Sea program for those of you interested in seeing what life upon a research vessel is like.  Students with a degree in the sciences and an interest in marine biology can volunteer to assist on a NOAA research trip much like the one I am on right now.  In fact, one of the members of the science team on this trip is a new graduate who is interested in getting involved in the NOAA program.  You can read more about NOAA and its opportunities by checking out the information available on their home page at NOAA Home.

Helen Haskell

Aboard NOAA Ship Fairweather

June 5 – 22, 2017

Mission: Hydrographic Survey

Geographic Area of Cruise: Southeast Alaska – West of Prince of Wales Island 

Date: June 7, 2017

Weather Data from the Bridge:

Latitude: 55 04.473 N

Longitude: 133 03.291 W

Wind: 9 knots from the east

Air temperature: 17C

Visibility: 10 miles

Barometer: 1004.2 hPa

Science and Technology Log

The mission of the Fairweather is to conduct hydrographic surveys for nautical charting. The Fairweather does this work in the waters off the United States Pacific coast, but principally in Alaskan coastal waters. The data is collected using sonar both by the Fairweather but also using a series of smaller boats that are launched as often as possible, each with a small crew of 3-4 people. These smaller boats are able to conduct the surveys much closer to the shoreline, and spend about 8-9 hours each day surveying a specific region. Many of the waters up here have had no recent data collected, and mariners are relying on charts that may have measurements taken in the 1800’s or 1900’s when technology was very different.

IMG_0282

NOAA Ship Fairweather

During the field season, Fairweather spends about 210 days at sea. During the rest of the year, the Fairweather stays at her homeport, allowing the crew to work on maintenance issues, take leave, work on the data and outfit the boat for the following season. During the field season, the boat conducts different legs of the research, spending 12-20 days out at sea at a time before returning to a port to re-supply. There are six departments on the ship: Command, Deck, Electronics, Engineering, Steward and Survey. Each person on the ship is hired with specific duties and responsibilities.

As a government vessel, the Fairweather is also available for use during the time of war or in case of an emergency. In the event of something along these lines, the ship and the officers would be transferred to the Armed Forces of the United States.

The Fairweather is named after the tallest peak in the Fairweather range in Alaska. The ship served in Alaskan waters for over 20 years but was decommissioned in 1988. In 2004, due to increasing demand for modern surveys in Alaska, it was retrofitted and put back in to the research fleet. Previously staterooms housed up to 4 people, but after the retrofit a maximum of two people share a room. The boat can house 58 people in 24 single staterooms and 17 double staterooms. The boat itself is 231 feet in length and 42 feet wide. Its cruising speed is 13 knots, with a survey speed of 6-10 knots.   The Fairweather has 7 levels, A-G, each containing many rooms and areas essential to the mission of this ship. Wires and pipes run throughout the ship with sensors monitoring equipments, sensors ready to trigger if needed. Lower levels of the ship contain tanks, ballast and engines. Diesel, drinking water and grey water are stored in the tanks. The next three levels contain staterooms, lots of machinery and storage, the Mess, the Galley, laundry, labs, the sick bay and one deck with small boat storage. The last two levels contain the ships Navigation Bridge, the data processing center, electronics office, and lots more equipment.

Personal Log

A few days in to my journey with the ship, things are starting to make more sense. While there are still doors I haven’t opened and rooms I am sure I have not been to, I feel that I am getting a better sense of the Fairweather and how it works, the roles that people play, and a slightly better understanding of what it means for home to be a ship.

There is a lot going on. Unlike many of the fisheries boats, where science staff works on a shift system, here on the Fairweather, much of the hydro data acquisition needs to be done on the small vessels during daylight. After the 8am meeting, boats are launched and the survey crew leave for the day. Meanwhile the rest of the scientists and survey crew works with the previously acquired data. Shift systems are in operation for most of the rest of the staff. There are always engineering projects and issues to sort out on a boat of this size, and engineers are always available and always problem solving. There are always NOAA Corps officers and deck crew on the bridge to monitor the ship and coordinate communication. From early in the morning there is always food to prepare, parts of the ship to be cleaned and decisions to be made, reviewed and modified. Somewhere around 4:30pm the survey boats return. Meal times and group meetings are places where most of the crew comes together to hear about how the day has gone and what is needed for the next day. After dinner, there is still work to be done. The day’s data needs to be processed in order for the plans for the next day to solidify. Small boats are checked after their day in the water, re-fueled and parts fixed if need be. After working hours the ship is patrolled hourly to make sure equipment is working and things are safe.

 

In between all these jobs, the crew does have down time. Those on a shift system hopefully manage to get some decent sleep, even if it is daytime. Laundry gets done. Personal emails are sent to communicate with families. Movies are watched in the lounge/conference room. Showers happen. People visit the exercise room. The ships store opens up for a while each night, allowing crew to splurge on a bag of chips or a candy bar. So, it’s a busy place. Whether it’s visible or not, there are always things going on.

 

In some very simple ways it is no different to your home or mine. There is food, shelter and water. In most other respects, it is very far removed from living on land. Most people don’t have breakfast, lunch and dinner with their work colleagues. Here we do. Most people don’t have bedrooms without windows in them. Here we do. Most people don’t have the floor swaying beneath their feet due to wave action. Here we do. And for what it’s worth, most people don’t get to look over the deck and watch curious sea otters swim by, knowing that a whale may breach any minute. Here we do.

 

 

Fact of the day:

NOAA has nine key focus areas: Weather, Climate, Fisheries, Research, Satellites, Oceans and Coasts, Marine and Aviation, Charting and Sanctuaries. NOAA employs 12,000 people worldwide, of which 6,773 are scientists and engineers studying our planet. NOAA’s roots began over 200 years ago with the establishment of the U.S. Coast and Geodetic Survey by President Thomas Jefferson. In 1870 the Weather Bureau was formed closely followed by the U.S. Commission of Fish and Fisheries. In 1970 these three organizations became the beginning of NOAA.

Word of the day: Knot

Knot, in nautical terms is a unit of speed.  One knot is the equivalent of going one nautical mile per hour.

What is this?

Science and Technology Log

People benefit from collaboration and science is brought further, faster and better because of it. This is true of Federal agencies as well. NOAA and the National Aeronautics and Space Administration (NASA) have been scientific partners for decades.

A place where the important work of these Federal agencies intersects is Earth. Good Earth systems research requires a complement of remote-sensing technology, modeling, and ground truthing. This interagency partnership makes clear the need for specialized expertise in different areas, which complement each other. The results are also cost-saving. A classic example is NOAA and NASA’s work with weather, climate, and other environmental satellites. Without these our nation would not know when to evacuate due to hurricanes or tornadoes, plus so much more. There are many ways NOAA and NASA work together to give us a better “eyes in the sky.”

Satellites and other research result in massive amounts of data. This is where sophisticated computer modeling helps. Despite all of our improvements in technology, at some point you need to put people on the ground…or sea or space.   

Today I visited the NASA Johnson Space Center in Houston, Texas (JSC). It is the famed headquarters of U.S. manned space flight. The facility was purposely built like a college campus to foster collaboration and innovation. Just like my upcoming trip aboard NOAA Ship Pisces, people need to go! They need to be there, whether that be space or sea, to figure out the science. No amount of satellites or computer modeling can replace what is gained by the human experience. We have pretty amazing robots now, but nothing beats good old fashioned people power. 

IMG_2922

The Robonaut 2. Still not as good as the real thing.

For my mission, we are looking at the abundance of fish species. There is remote sensing used as well, but we also need to fish, and get out in open water by ship. This is vital for the ecological and economic health of the Gulf of Mexico. The International Space Station (ISS) puts humans in space. There have been many positive effects from this work in our everyday lives such as Velcro, water recycling technology, MRI machines, cell phones, and fire fighting respirators. Working in microgravity is also bringing us one step closer to ending breast cancer.         

You can interpret the title of this blog post a few different ways. Independently and together, NOAA and NASA work to progress science. These effects have built over decades to benefit humanity and our relationship with Earth in numerous ways. The two agencies are also continuing on this journey. It remains a work in progress. Our future depends on it.

Personal Log

Yesterday was an auspicious start to my trip. The museum itself is a treat for all ages as well as the tram tours. There are two tram tours you can take at Johnson Space Center, the red and blue. A trip to JSC is definitely not complete without a tour! I took both and enjoyed the high quality audio commentary from astronauts of many missions that accompany the drive.

First stop was the Space Vehicle Mockup Facility. I wish I was there during the workweek to see it in action. There are mockups of the International Space Station (ISS) for training, a model Russian Soyuz space capsule (which is how our astronauts now get into space since the last shuttle retired in 2011), tests related to the future of manned space flight with NASA’s Orion spacecraft, manned rovers for future asteroid and Mars missions, and even a robotics playing field where high school teams compete.

This slideshow requires JavaScript.

The other tour took me to the White Flight Control Room. Since 1996, this mission control center has been used for shuttle missions, ISS mission control, and is now used for simulations to train mission controllers. It was noted that the room will become one of deep historical significance when it becomes Orion Mission Control.

Both tours end at Rocket Park. It is awe-inspiring to see a Mercury-Redstone spacecraft-booster like the one that propelled New Hampshire’s own Alan Shepard into space. I stood next to a F-1 rocket engine and then it was time to see, in my opinion, the crown jewel of Rocket Park: The Saturn V (Five). Even in person it is difficult to grasp its size.

NASA Johnson Space Center deftly combines the romantic and sometimes tragic history of manned space flight with the hopes and excitement of current and future missions.

Halloween happens to be when I start teaching about space.

We landed on the moon in 1969. The average age of NASA engineers in the Apollo program was 27. This means that when they heard President Kennedy say, “We choose to go to the moon” many were still in school!

This is one I think about every time I fly…We landed on the moon before adding wheels on luggage.

Science and Technology Log

Throughout my experience as a Teacher at Sea, it has been evident that the ocean and humans are inextricably interconnected.  This was apparent from my very first evening in Homer when I came across an eagle poised next to its colossal nest assembled in the middle of three rusty pier pilings.  An illustration of nature conforming to our presence on the water and what we deem to be acceptable for our environment.

But, humankind must sometimes accept and conform to nature.   The fishermen of Uganik Bay have built their fishing camps above the tidal line and strung out their nets where the fish traditionally run.  Most of the men and women who live here have chosen to do so because this is where the fish are found.  One such gentlemen is Toby Sullivan, a commercial fisherman, who in 1975 headed to Alaska from Connecticut to work on the Alaskan pipeline.  Instead, he found himself fishing vs. working on the pipeline and to this day is still gill-netting salmon to make a living.  Toby’s fishing camp, East Point, located on the south shore of the Uganik Bay, has had a net on the site for the past 80 years.  And, unfortunately, we drifted into that site when a strong current took us by surprise while we were gathering water quality data over the side of the small sonar vessel.  When this happened, Toby and his crew worked swiftly and diligently to secure their fishing gear while NOAA divers were summoned from the Rainier to safely help our vessel leave the area.

A few evenings later, Mr. Sullivan and his crew came on board the Rainier as dinner guests and a rich discussion of hydrographic work and fishing gear followed.  He explained in detail how he sets his fishing gear and offered the idea that a radio channel be utilized between NOAA’s small vessels that are working around fishing gear and the local fisherman, in order to facilitate better communication.

As I watched the exchange of ideas between Commanding Officer E.J. Van Den Ameele and Mr. Sullivan it appeared that both men recognized that both parties were interested in Uganik Bay because the ocean and humans are inextricably interconnected.  The Rainier’s primary mission in Uganik Bay is to gather the necessary data to create accurate and detailed charts for navigational use by the local fisherman and other mariners.  As a commercial fisherman, Mr. Sullivan’s primary interest is to keep his gear and crew safe while continuing to make a living from the harvest of local fish.

Today the Rainier continues on with its mission of hydrographic work at sea using the multibeam sonar which is located on the hull of the Rainier.  The swath that multibeam sonar on the Rainier covers is similar to the swath of the multibeam sonar on the smaller boats; the coverage area depends on the depth of the water.  For example, at our current water depth of 226 meters, the swath of each pass that the multibeam sonar makes an image of  is 915 meters wide.  This evening, upon the completion of the work with the Rainier’s multibeam sonar we will depart the area and be underway for Kodiak, AK.


All Aboard!

Tell us a little about yourself:

I grew up in a military family, so I was actually born in England and have lived in Florida, Nebraska, Montana, Oregon and Washington.  I went to college at Oregon State University located in Corvallis, OR and majored in earth systems with a focus on marine science.

How did you discover NOAA?:  

Ever since I was a little kid instead of having posters of bands etc… I had posters of maps.  NOAA Corps participated in career fairs at my university.  I stopped at their booth my sophomore year and again my junior and senior year to learn more about their program.  After learning more about NOAA I also focused on the marine aspect of earth science because I knew I wanted to work with them.  Initially I didn’t know about the civilian side of NOAA, so I applied for the NOAA Corps two times and wasn’t accepted into the program, although I was an alternate candidate once.  At some point, when speaking with an officer he told me to apply for a civilian position with NOAA.  So, I applied and was accepted.

I’m happy to be on the civilian side because I get to work on the science side of the operations all of the time and I get to keep my beard!

Survey Technician Michael Bloom monitors the settings of the Rainier’s multi beam sonar

What are your primary responsibilities when working on the ship?:

I am survey tech and my primary duties include data acquisition and data processing.  We can work to become the Hydrographer in Charge on the surveys after enough time working in the field and, if after the Field Operations Officer observes us, he feels confident that we are ready. Eventually I’d like to work for NOAA as a physical scientist, a job that would have me going out to sea several times a year but one that is primarily land based.

What do you love about your work with NOAA?:

I get paid to travel!  I go to places that people pay thousands of dollars to visit and I actually get paid thousands of dollars to go there.  I enjoy that I can see the real world application of the work that I do.  Scientists are using our data and ultimately we could be saving lives by creating such accurate charts.


Personal Log

NOAA’s website for the Rainier states that the Rainier is one of the most productive and advanced hydrographic ships in the world.  After spending two weeks working on board the Rainier, I couldn’t agree more.  However, I don’t believe that it is only the cutting-edge technology that makes the Rainier one of the best hydrographic ships in the fleet.  But rather a group of outstanding people at the helm of each of the different technical aspects of hydrography.  Hydrographic surveying has many steps before the end product, a chart, is released.  The people I met on board who are part of that process are teaching each other the subtle nuances of Rainier’s hydrographic mission in order to become even better at what they do.  I am grateful for the time that the crew and Officers have graciously given me while I have been on board.  I felt very welcome from the moment a NOAA Corps member picked me up at the airport throughout my stay on the Rainier as I continued to pepper everybody with questions.  Thank you Rainier!  I am confident that when I return to my classroom your efforts to help me better understand your work of hydrographic surveying will pay off.   You have given me the gift of new knowledge that, when shared with my students has the potential to ignite in them the same excitement and passion for science that so many of you possess.

Approaching Weather

When an anchor is dropped, forces in the ocean will cause this massive object to drift as it falls.  Last year, after the anchor of mooring 12 was dropped, an acoustic message was sent to the release mechanism on the anchor to locate it.  This was repeated in three locations so that the location of the anchor could be triangulated much like how an earthquake epicenter is found.  This was repeated this year for mooring 13 so next year, they will know where it is.  From where we dropped the anchor to where it fell, was a horizontal distance of 3oo meters.  The ocean moved the 9300 pound anchor 300 meters.  What a force!

The next morning as the ship was in position, another acoustic message was sent that triggered the release of the glass floats from the anchor. Not surprisingly, the floats took nearly an hour to travel up the nearly 3 miles to the surface.

Float recovery

A small boat went to retrieve the mooring attached to the floats

Once the floats were located at the surface, a small boat was deployed to secure the end of the mooring to the Hi’ialakai. The glass floats were loaded onto the ship.  17 floats that had imploded when they were deployed last year.  Listen to imploding floats recorded by the hydrophone.  Implosion.

Next, came the lengthy retrieval of the line (3000+ meters). A capstan to apply force to the line was used as the research associates and team arranged the line in the shipping boxes. The colmega and nylon retrieval lasted about 3 hours.

Once the wire portion of the mooring was reached, sensors were removed as they rose and stored. Finally the mooring was released, leaving the buoy with about 40 meters of line with sensors attached and hanging below.

The NOAA officer on the bridge maneuvered the ship close enough to the buoy so that it could be secured to the ship and eventually lifted by the crane and placed on deck. This was followed by the retrieval of the last sensors.

Mooring removal was accomplished in seas with 5-6 feet swells at times. From my vantage point, everything seemed to go well in the recovery process. This is not always the case. Imagine what would happen, if the buoy separated from the rest of the mooring before releasing the floats and the mooring is laying on the sea floor? What would happen if the float release was not triggered and you have a mooring attached to the 8000+ pound anchor?  There are plans for when these events occur.  In both cases, a cable with a hook (or many hooks) is snaked down to try and grab the mooring line and bring it to the surface.

Now that the mooring has been recovered, the science team continues to collect data from the CTD (conductivity/temperature/depth) casts.  By the end of tomorrow, the CTDs would have collected data for approximately 25 hours.  The data from the CTDs will enable the alignment of the two moorings.

The WHOTS (Woods Hole Oceanographic Institution Hawaii Ocean Time Series Site) mooring project is led by is led by two scientists from Woods Hole Oceanographic Institution;  Al Plueddeman and Robert Weller.  Both scientists have been involved with the project since 2004.  Plueddeman led this year’s operations and next year it will be Weller.  Plueddeman recorded detailed notes of the operation that helped me fill in some blanks in my notes.  He answered my questions.  I am thankful to have been included in this project and am grateful for this experience and excited to share with my students back in Eugene, Oregon.

Al Plueddeman

Al Plueddeman, Senior Scientist

The long term observations (air-sea fluxes) collected by the moorings at Station Aloha will be used to better understand climate variability.  WHOTS is funded by NOAA and NSF and is a joint venture with University of Hawaii.  I will definitely be including real time and archived data from WHOTS in Environmental Science.

Personal Log

I have really enjoyed having the opportunity to talk with the crew of the Hi’ialakai.  There were many pathways taken to get to this point of being aboard this ship.  I learned about schools and programs that I had never even heard about.  My students will learn from this adventure of mine, that there are programs that can lead them to successful oceanic careers.

Brian Kibler

Brian Kibler

I sailed with Brian Kibler in 2013 aboard the Oscar Dyson up in the Gulf of Alaska.  He completed a two year program at Seattle Maritime Academy where he became credentialed to be an Able Bodied Seaman.  After a year as an intern aboard the Oscar Dyson, he was hired.  A few years ago he transferred to the Hi’ialakai and has now been with NOAA for 5 years.  On board, he is responsible for rigging, watch and other tasks that arise.  Brian was one of the stars of the video I made called Sharks on Deck. Watch it here.

Tyler Matta

Tyler Matta, 3rd Engineer

Tyler Matta has been sailing with NOAA for nearly a year.  He sought a hands-on engineering program and enrolled at Cal Maritime (Forbes ranked the school high due to the 95% job placement) and earned a degree in maritime engineering and was licensed as an engineer.  After sailing to the South Pacific on a 500 ft ship, he was hooked.  He was hired by NOAA at a job fair as a 3rd engineer and soon will have enough sea days to move to 2nd engineer.

 

 

There are 6 NOAA Corps members on  the Hi’ialakai.  They all went through an approximately 5 month training program at the Coast Guard Academy in New London, CT.  To apply, a candidate should have a 4 year degree in a NOAA related field such as science, math or engineering.  Our commanding officer, Liz Kretovic, attended Massachusetts Maritime Academy and majored in marine safety and environmental protection.  Other officers graduated with degrees in marine science, marine biology, and environmental studies.

ENS Chappelle

NOAA Ensign Nicki Chappelle

Ensign (ENS) Nikki Chappelle is new to the NOAA Corps.  In fact, this is her first cruise aboard the Hi’ialakai and second with NOAA.  She is shadowing ENS Bryan Stephan for on the job training.  She spent most of her schooling just south of where I teach.  I am hoping that when she visits her family in Cottage Grove, Oregon that she might make a stop at my school to talk to my students.  She graduated from Oregon State University with degrees in zoology and communication.  In the past she was a wildfire fighter, a circus worker (caring for the elephants) and a diver at Sea World.

All of the officers have 2 four hour shifts a day on the bridge.  For example ENS Chappelle’s shifts are 8am to 12pm and 8pm to 12am.  The responsibilities of the officers include navigating the ship, recording meteorological information, overseeing safety.  Officers have other tasks to complete when not on the bridge such as correcting navigational maps or safety and damage control. ENS Stephan manages the store on board as a collateral assignment.  After officers finish training they are sent to sea for 2-3 years (usually 2) and then rotate to land for 3 years and then back to sea.  NOAA Officers see the world while at sea as they support ocean and atmospheric science research.

Frank Russo

ET Frank Russo

Electronics technician (ET) seem to be in short supply with NOAA.  There are lots of job opportunities.  According to Larry Wooten (from Newport’s Marine Operation Center of the Pacific), NOAA has hired 7 ETs since November.  Frank Russo III is sailing with NOAA for the first time as an ET.  But this is definitely not his first time at sea.  He spent 24 years in the navy, 10 at Military Sealift Command supporting naval assets and marines around the world.  His responsibilities on the Hi’ialakai include maintaining navigational equipment on the bridge, making sure the radio, radar and NAVTEX (for weather alerts) are functioning properly and maintaining the server so that the scientists have computer access.

I have met so many interesting people on the Hi’ialakai.  I appreciate everyone who took the time to chat with me about their careers or anything else.  I wish I had more time so that I could get to know more of the Hi’ialakai crew.  Thanks.  Special thanks to our XO Amanda Goeller and Senior Scientist Al Plueddeman for reviewing my blog posts.  And for letting me tag along.

 

Did You Know?

The buoy at the top of the mooring becomes a popular hang out for organisms in the area. As we approached mooring 12, there were several red-footed boobies standing their ground. There were also plenty of barnacles and other organisms that are planktonic in some stage of their lives. Fishing line is strung across the center of the buoy to discourage visitors but some still use the buoy as a rest stop. The accumulation of organism that can lead to corrosion and malfunction of the equipment is biofoul.

Science and Technology Log

The ocean supports many ecosystems which contain a diversity of living things ranging in size from tiny microbes to whales as long as 95 feet.  Despite the fact that I am working on a hydrographic ship, when out on a skiff or while in port, I have had the opportunity to view some of these ecosystems and a number of the species found in them.

While the Rainier was in port in Homer, I spent some time at the Kachemak Bay National Estuarine Research Reserve which, like other estuaries, is among the most productive ecosystems in the world.  An estuary, with accompanying wetlands, is where the freshwater from a river meets and mixes with the salt water of the sea.  However, there are some estuaries that are made entirely from freshwater.  These estuaries are special places along the Great Lakes where freshwater from a river, with very different chemical and physical characteristics compared to the water from the lake, mixes with the lake water.

Because estuaries, like the Kachemak Bay Estuary, are extremely fragile ecosystems with so many plants and animals that rely on them, in 1972 Congress created the National Estuarine Research Reserve System which protects more than one million estuarine acres.

ESTRE

Kachemak Bay National Estuarine Research Reserve

All estuaries, including the freshwater estuaries found on the Great Lakes, are affected by the changing tides.  Tides play an important part in the health of an estuary because they mix the water and are therefore are one of several factors that influence the properties (temperature, salinity, turbidity) of the water

Prior to my experience in Alaska, I had never realized what a vital role tides play in the life of living things, in a oceanic region.  Just as tides play an important role in the health and function of estuaries, they play a major role in the plants and animals I have seen and the hydrographic work being completed by the Rainier.  For example, the tides determine when and where the skiffs and multi beam launch boats will be deployed.  Between mean low tide and high tide the water depth can vary by as much as 12 feet and therefore low tide is the perfect time to send the skiffs out in to document the features (rocks, reefs, foul areas) of a specific area.

DSCN0069 (2)

Rock feature in Uganik Bay (actually “the foot” mentioned in previous blog) Notice tidal line, anything below the top of that line would be underwater at high tide!

In addition to being the perfect time to take note of near shore features, low tide also provides the perfect opportunity to see some amazing sea life!  I have seen a variety of species while working aboard the Rainier, including eagles, deer, starfish, dolphins, whales, seals, cormorants, sea gulls, sea otters and puffins.  Unfortunately, it has been difficult to capture quality photos of many of these species, but I have included some of my better photos of marine life in the area and information that the scientists aboard the Rainier have shared with me:

Tufted Puffins:  Tufted Puffins are some of the most common sea birds in Alaska.  They have wings that propel them under water and a large bill which sheds its outer layer in late summer.

puff2

Double Crested Cormorants:  Dark colored birds that dive for and eat fish, crabs, shrimp, aquatic plants, and other marine life.  The birds nest in colonies and can be found in many inland areas in the United States.  The cormorants range extends throughout the Great Lakes and they are frequently considered to be a nuisance because they gorge themselves on fish, possibly decimating local fish populations.

Pisaster Starfish:  The tidal areas are some of the favorite areas starfish like to inhabit because they have an abundance of clams, which the starfish love to feed on.  To do so, the starfish uses powerful little suction cups to pull open the clam’s shell.

Glaucous-winged Gull:  The gulls are found along the coasts of Alaska and Washington State.  The average lifespan of Glaucous-winged Gull is approximately 15 years.

Glaucous-winged Gull watching the multi beam sonar boat

The hydrographic work in Uganik Bay continues even though there are moments to view the wildlife in the area.  I was part of the crew on board a boat equipped with multi beam sonar which returned to scan the “foot feature” meticulously mapped by the skiff.  During this process, the multi beam sonar is driven back and forth around the feature as close as the boat can safely get.  The multi beam does extend out to the sides of the boat which enables the sonar to produce an image to the left and right of the boat.  The sonar beam can reach out four times the depth of the water that the boat is working in.  For example, if we are working in six feet of water the multi beam will reach out a total of 24 feet across. Think of the sonar as if it was a beam coming from a flashlight, if you shine the light on the floor and hold the flashlight close to the floor, the beam will be small and intense.  On the other hand, if you hold the flashlight further from the floor the beam of light will cover a wider area but will not be as intense. The sonar’s coverage is similar, part of why working close to the shore is long and tedious work: in shallow water the multi beam does not cover a very wide area.

All Aboard!

I met Angelica on one of the first days aboard the Rainier and later spent some time with her, asking questions as she worked .  Angelica is very friendly, cheerful and a pleasure to talk with!  She graciously sat down with me for an interview when we were off shore of Kodiak, AK before returning to Uganik Bay.

Assistant Survey Technician Angelica Patyten works on processing data from the multi beam sonar

Tell us a little about yourself:

I’m Angelica Patyten originally from Sacramento, CA and happy to be a part of NOAA’s scientific mission!  I have always been very interested in marine science, especially marine biology, oceanography and somewhat interested in fisheries.  Ever since I was a little kid I’ve always been interested in whales and dolphins.  My cousin said that when I was really young I was always drawing whales on paper and I’d always be going to the library to check out books on marine life.  I remember one of the defining moments was when I was in grade school, we took a trip to see the dolphins and orca whales and I thought they were amazing creatures.

As far as hobbies, I love anything that has to do with water sports, like diving and kayaking.  I also want to learn how to surf or try paddle boarding as well.

How did you discover NOAA?:

I just kind of “stumbled upon” NOAA right after I had graduated from college and knew that I wanted to work in marine science.  I was googling different agencies and saw that NOAA allows you to volunteer on some of their vessels.  So, I ended up volunteering for two weeks aboard the NOAA ship Rueben Lasker and absolutely loved it.  When I returned home, I applied online for employment with NOAA and it was about six months before I heard from back from them.  It was at that point that they asked me if I wanted to work for them on one of their research vessels.  It really was all good timing!

What are your primary responsibilities when working on the ship? 

My responsibilities right now include the processing of the data that comes in from the multi beam sonar.  I basically take the data and use a computer program to apply different settings to produce the best image that I can with the sonar data that I’m given.

What do you love about your work with NOAA?

I love the scenery here in Alaska and the people I work with are awesome!  We become like a family because we spend a lot of time together.  Honestly, working aboard the Rainier is a perfect fit for me because I love to travel, the scenery is amazing and the people I work with are great!


Personal Log:

Geoffrey Chaucer wrote, “time and tide wait for no man.”  Chaucer’s words are so fitting for my time aboard the Rainier which is going so quickly and continues to revolve around the tides.
