Science and Technology Log

In the fish lab, after the haul is sorted out, a sample of each species are randomly selected to undergo additional measurements and data collection.  One of the primary pieces of information needed is the lengths for about 300 pollock per haul.  The length of the pollock is important because larger fish have larger internal organs.  The internal organ that matters most to this survey is the size of the swim bladder since this is what give us the echo that can be picked up by our acoustic transducers.

According to the NOAA Ocean Service, “If fish relied solely on constant swimming to maintain their current water depth, they would waste a lot of energy. Many fish instead rely on their swim bladder, a dorsally located gas-filled organ, to control their stability and buoyancy in the water column. The swim bladder also functions as a resonating chamber that can produce and receive sound, a quality that comes in handy for scientists locating fish with sonar technology.”

To process a trawl sample, the pollock are put into baskets and weighed. One basket is selected at random to obtain the lengths and weights of individual fish. 30-35 Fish are selected for otolith samples (ear bones) that can be used to age the fish.  These fish are also inspected to look for the sex of the fish and their maturity stages.  There are 5 different maturity stages for pollock:  immature, developing, pre-spawning, spawning, and spent.  Since the fish already needs to be cut open for this process, we will sometimes look at the stomach contents of the fish as well to see what they are eating.  Based off of stomach contents, one of the main food sources for pollock in the Bering Sea this summer are euphausiids, or krill.

Flow meter

Flow Meter used on the Methot Net. This is a calibrated instrument and we use the number of spins to measure the volume of water going through the net. This is an important tool for determining the catch per unit effort.

In addition to trawl samples, we also are taking samples of Euphausiids with a special tool called a Methot net. Four Methot samples will be taken on each leg of this research survey.  A Methot net includes a sturdy metal frame of a set circumference with a net attached to the back. The net is a very fine mesh (small holes), so that the small euphausiids don’t escape.  A flow meter is attached that measures the volume of water that is going through the net.

The euphausiids are a very important component of the marine food web in the Bering Sea.  Euphausiids eat very small phytoplankton and zooplankton, so they are omnivores.  Pollock eat the euphausiids, and then the pollock are eaten by marine animals such as seals, orcas, large cod, and even larger pollock.  Humans also eat pollock, often in the form of imitation crab meat and the fish filet sandwiches from fast food chains.

Euphausiids being counted

Euphausiids being separated into groups of 10 so that they can be counted. This only represents a small sample of what was brought in with the Methot. There were 1,110 in total counted.

Once the Methot net has come back on the ship at the end of the haul, a scoop (sub-sample) of them is taken and counted.  Fish larvae and anything else that is not euphausiids is taken out and counted separately and then we go to work counting to get a total number of euphausiids from our sample.  In our small sub-sample of .052 kg, our count was 1,110 euphausiids.  Based off of the total haul weight of 2.12 kg, we are able to estimate the total number of euphausiids for this haul to be 45,251.  This number is calculated based off the total number and weight of our sub-sample, compared to the total weight of the Methot haul.

Personal Log

I finally saw Orcas!!  All of the running around on the ship was worth it!  We always seem to be heading in opposite directions so I have seen mostly just dorsal fins, but I’ll take it!  One morning I finally saw them from a closer distance and was able to see the white patch near the eye.  I feel like I will be remembered by everyone on the ship as the “crazy whale-obsessed teacher,” but I can live with that.

First Orca

One of the side experiments happening on the ship looks at the survival rate of fish caught on traditional fishing lines versus fish caught in trawl nets.  One pollock had been caught and all of us on the ship decided the name should be Jackson Pollock.  Jackson survived for a few days, but didn’t last past 6/15/18.  The next day six new fish were put into the tank after a trawl catch, and after 24 hours, only two were still alive.

 

NOAA Careers and Unexpected Learning Opportunities

I have been trying to talk to everyone on the ship about how they first got interested in this type of work and exactly what their role is for day to day operations.  There are so many different career options that can allow you to live on ships and be involved with scientific research.

The past few days I have spent time trying to learn as much as I can about everything related to the ship.  I spent time speaking with Commanding Officer (CO) Michael Levine and Ensign (ENS) Sony Vang about their ship and land assignments and the requirements of the NOAA Corps.  ENS Vanessa Oquendo showed me how some of the ship’s controls work.  They are regularly focused on navigation (on a paper chart and electronically), and communication with other ships about positioning, weather, and the speed and direction of the ship.  There is a lot to consider and to maintain 24/7.

Easy button and emergency affirmation

A few of my favorite buttons on the ship.

Getting the nets in and out of the water is a very complicated process and involves many different ropes, chains and weights.  I noticed this really cool type of knot that seemed to undo itself, so I asked one of the Deck Crew members, Jay Michelsen to teach me some cool ship knots.  I learned how to make:  bowline knots, flying bowline knots, cow hitch knots, daisy chains, double daisy chains, and a way to finally wrap up headphones so that they won’t tangle themselves.

Matthew Phillips and Scientist Mike Levine taught me how to fillet a fish which will be useful since I enjoy cooking so much! I will no longer be intimidated to buy fish whole.  We got some practice on a spare cod that we caught and a few rockfish.

One of the licensed engineers, Becca Joubert, gave me a tour of the engine room and I was able to see the engines, winches, rudder, water filtration systems, and the repair shop.  I didn’t realize that fuel was held in different tanks, but it works best that way because of safety and because it helps to distribute the weight all around the ship better.

 

 

Did You Know?

The NOAA Ship Oscar Dyson was named after a commercial fisherman named Oscar Dyson.   There is a smaller boat on board named the Peggy Dyson after his wife, who would broadcast the weather forecast twice a day every day to local ships as well as personal announcements and important sports scores.

Things to Think About:

Dolphins and Orcas eat a variety of fish, squid, and sometimes other marine mammals, while large whales such as blue whales and humpbacks mostly rely on krill as their main food source. Why would such large marine mammals feed primarily on tiny krill?

Since there is a relationship between pollock and euphausiids, as the number of pollock grows, what is a reasonable prediction about the number of euphausiids?

Science and Technology Log

There are many different types of samples that are taken on NOAA Ship Oscar Dyson.  Some of the samples collected on the ship are for the projects of the scientists that are here currently, and other samples are brought back for scientists working on related NOAA projects.  The scientists that I am working with are based out of NOAA in Seattle, Washington.

CTD through Port Hole

View through a port hole of the Hero Deck on NOAA Ship Oscar Dyson of a scientific instrument called a CTD. The CTD is sent to the bottom of the ocean and back at specific locations. The CTD collects information related to conductivity (salinity), temperature, and depth. The grey bottle attached to the side collects a water sample that will be analyzed later.

One of the projects that I have been helping with most frequently is processing the trawl samples once they have been collected.  When a trawl sample is collected, a large net is lowered off the stern of the ship that will collect the sample of fish (hopefully mostly pollock)  and other living things. The net also functions as a vessel to hold scientific instruments that collect other types of information. There is a camera (cam trawl) that is attached to the net and this records video that can be watched through a computer to actually see what is being caught in the net.  

Cam Trawl Jellyfish

Picture of a jellyfish captured by the Cam Trawl

Another useful instrument is the FS70, a sonar device that rides above the opening of the trawl net to ping on the fish going into it. Viewed from a screen on the Bridge in real time, this gives the scientists an idea of exactly how many fish are going into the net, so that they can adjust the depth of the net, or change the length of time for the trawl survey.  The goal for each trawl sample is to collect at least 300 pollock.

Once the net has been brought in after haulback, the opening at the codend (bottom) of the net is released to allow the sample to be put in a metal tub called the table.  The table is capable of holding approximately 1 ton, or 2,000 pounds worth of fish.  Sometimes if there is more than can fit on the table, the crew will split the catch in half so that we are only measuring a portion of what was collected.  The rest of the fish are stored in another tank on the deck.  If we don’t end up with enough pollock on the table, we may need to pick through the other half that was saved on deck until we get enough. Measuring too few of them may not represent the accurate length compositions of the pollock.

On June 11th we collected trawl sample #7.  This haul was filled with mainly jellyfish, with pollock and a few herring.  The weight of this haul was very close to the amount that the table can hold so it was decided to split the catch.  Once we looked at what was put on the table and we realized that it wasn’t going to be enough pollock, Mike and Sarah jumped into the spare tank and pulled out all of the fish (whole haul) so that we would have enough to get as close to that 300 number as possible.

Funny in the fish lab

When the fish come into the fish lab, we sort out the different species and put them into separate baskets.  Each basket is weighed by species and input into a system called CLAMS (Catch Logging for Acoustic Midwater Surveys).  After all of the species have been sorted, a percentage of each species will be measured by length.  Another percentage of each species will be measured by length and weight.

 

From the pollock sample collected, 30 will be randomly picked to have their otoliths removed.  The otolith is the ear bone of the fish and it can be used to determine the age of that specific pollock.  They have rings, similar to tree rings that can be counted.  For information click here.

Personal Log

I have not been shy with anyone onboard about the fact that I would love to see whales if they are around the ship.  I feel like this has almost turned into a game at my expense, but I don’t mind.  There have been multiple times when there have been “whales” and as soon as I run up the 3 flights of stairs and get to the Bridge, the whales are suddenly gone.  I think they are secretly timing me to see how quickly I can run up the stairs!  The exercise is good for me anyways.

I’ve finished two books already, which has been really nice.  I know that I love to read, but never really take the time anymore because it always seems like there is something else that I should be doing instead.  There’s a bookshelf here in the lounge, so I’ll find another to read after I finish the last one that I brought.

I try to spend some time outside every day, and it is so peaceful.  I don’t think I’ll ever get tired of waking up and looking at the ocean.  I don’t want to take any bit of this experience for granted.  I am so grateful that I have this opportunity and I want to take in as much of it as I can.  As I get to know more people on the ship I am starting to get to learn more from everyone about exactly what they do and why they chose to make this their profession.

Everyone thinks of scientists, NOAA Corps officers, and engineers as being very serious all of the time, but that couldn’t be further from the truth.  Professionalism is incredibly important and is always the focus, but there is also space for fun.  Every other day there is a photo competition where a picture is taken somewhere on the ship and you need to find out where it was taken and submit your answer.  There are also plastic Easter eggs that keep popping up everywhere filled with positive messages, or candy.  The “Oscar Dyson Plan of the Day” sometimes has puzzles to figure out on it as well as important information such as location, meal times, sunrise/sunset times and any other important information.

Science and Technology Log

On Wednesday, June 6th 2018, NOAA Ship Oscar Dyson left port from Dutch Harbor Alaska at 08:00 to go and fuel up for the upcoming voyage.  Fueling the ship takes hours and during that time, NOAA Ship Oscar Dyson took on over 50,000 gallons of fuel.  After the ship was fueled, it searched for a spot in Captain’s Bay to calibrate the acoustic equipment. In order to calibrate the equipment, a metal ball made of tungsten carbide was suspended beneath the boat under the center board. The ball has known acoustic return values based on density and purity of the metal. It is attached at three points to the boat so that it can be moved under the center board to calibrate each transducer..  The location of the ball is adjusted under each transducer one at a time to the center of each beam.  Adjustments to the equipment will be made if the return from the ball at each transducer is not as it is expected to be.  The scientists had to change the depth of the ball in the water in order to avoid the fish to get an accurate reading.  The calibration can be different depending on the temperature of the water and the salinity (saltiness) of the ocean. A second calibration will be taken at the end of the research cruise and the average will be used in the necessary calculations.  Once calibration was complete and the equipment was retrieved, the ship started heading to the beginning location of the first transect line.

The journey from our calibration point to the start of the first transect line took approximately 23 hours, traveling at 12-13 knots.  The ship reached the northern end of the first transect line at approximately 21:00 (9 pm) on June 7th. The first trawl sample was taken shortly after at sunset, which was approximately 23:30 (11:30 pm).  This is not an ideal time to collect a trawl sample though since the fish move and behave differently at night.  The first trawl sample of the survey that I participated in was on 6/8/18 at approximately 15:30.

Operations on the ship run 24 hours a day, so some members of each team onboard need to be awake and working at all times.  Shifts for the science team are 12 hours long and the day shift runs from 04:00 (4 am) to 16:00 (4 pm) and the night shift is from 16:00 (4 pm) to 04:00 (4 am).  I am assigned to the day shift along with Chief Scientist Denise McKelvey and Fisheries Biologists Sarah Stienessen, Mike Levine, and Scott Furnish. On the night shift for the science team are Nate Lauffenburger, Darin Jones and Matthew Phillips.

 

In order to collect a trawl sample, members of basically every department on the ship are involved.  The NOAA Corps officers are on the Bridge driving the ship, charting the course that the ship will be traveling on as it collects it’s samples, as well as keeping track of the net, and all of the other duties that they regularly hold.  The stewards keep us all fed and happy. The deck crew are in charge of making sure that all of the nets are hooked up properly and are put into the water correctly as well as controlling the winches that release the nets. The engineers make sure that all equipment is functioning properly.  The survey technicians ensure that all of the scientific instruments used for making any type of measurements are attached to the net at different points, mainly on the kite.  The “kite” is a section of the net primarily used for holding scientific instruments. Some of the scientists are preparing the fish lab and getting dressed in waterproof gear, while the Chief Scientist is on the Bridge with the officers giving direction about where and when to start and stop trawling and exactly how deep the nets should be set. Adjustments to the net are regularly made during the sample collection.

The locations for when trawl samples will be collected is not pre-determined before the start of the research cruise.  The sites for samples are determined in real time by looking at the data collected from the acoustic pings being sent out by the transducers.  There are 5 different frequencies( measured in kilohertz) sent out by the ship’s transducers: 18 kHz, 38kHz, 70 kHz, 120 kHz, and 200 kHz.  The acoustic frequency that may best indicate the presence of pollock is 38 kHz. The chief scientist decides when she wants to “go fishing” based off of looking at the results coming back as echoes to the ship.

 

Acoustic data points collected at 5 wavelengths

This is what the acoustic data points look like as the ship is moving on the water. All 5 different frequencies are depicted in this image. The top left is 18kHz, bottom left is 38kHz (best for pollock), top right is 70kHz, middle right is 120kHz and the bottom right is 200kHz. Each dot represents an echo received by the ship’s transducers after the sound hits something in the water. The solid red band near the top of each window is the depth of the sonar transducer sending the acoustic pings, while the heavier red band at the bottom of each window is the sea floor.

On this leg of the research cruise thus far, 3 trawl samples have been collected from the transect lines.  I will include more detailed information and photos of the fish processing protocol in my next blog. In the next three pictures, there are temperature and depth profiles of our sample collection.  The depth (in meters) is shown by the shape of the line as it rises and falls, and the color shows the temperature (in degrees Celsius) that goes with the scale on the right of each figure. More specific details are underneath each image.haul 1 profile

Personal Log

Now that the ship is in the middle of the Bering Sea and is moving, I have learned an important lesson:  You can’t trust the floor. I know that sounds weird, but usually you know exactly where the floor is going to be when you are walking, but when the ship is moving in the water, the floor may be higher or lower than expected, causing a lot of wobbling.  This is especially challenging for someone who is as naturally clumsy as I am. There are times when I feel like a toddler learning to walk again, but I am getting more and more used to it already. At night it feels like being gently rocked to sleep.

I’m learning my way around the ship and I am starting to not walk right past the doors that I need to go into a few times before I remember that it’s the right place.  I am also getting more familiar with the people onboard as well as the schedule. Since my shift that I am working on is from 04:00 (4 am) to 16:00 (4 pm), it took a few days for me to adjust and everyone was very patient with me.  Coffee definitely helps! The meal times are as follows: Breakfast 07:00, Lunch 11:00, Dinner 17:00 and there are always some snacks available in the Galley.

In my downtime on the ship, I have found a new favorite location; the flying bridge!  The flying bridge is located above the Bridge (where the Ship is controlled).  There is a chair up there that makes the perfect spot on a nice day to sit and read for a little while.  It is windy and cold, but worth it!  The view from up there is pretty amazing!

Did You Know?

The NOAA Commissioned Officer Corps is one of the 7 uniformed services in the United States.  The other 6 include:  Army, Marine Corps, Navy, Airforce, Coast Guard, and the Public Health Service Commissioned Corps.

Math Challenges!!!!

If the Dyson regularly travels at 12.5 knots, how many miles per hour is it going?  (Hint: you may want to look at my previous blog before you try this.)

Currently 9 of the people aboard the NOAA Ship Oscar Dyson are women.  If there are 31 total people on the ship, what percentage of them are women?

Science and Technology Log

On this leg of the Research Cruise in the Eastern Bering Sea I will be helping a team of NOAA scientists collect data about a fish species called Pollock.  The datum (plural of data) that are collected will help to set the limits for how much pollock the fishing boats are allowed to catch. The data also allow scientists to track the populations of the pollock to look for patterns.  For additional information on Pollock, visit the NOAA fisheries website here.

During the survey, acoustic (sound) signals will be sent into the water by transducers at different frequencies and these acoustic signals will bounce off of the objects in the ocean and bounce back to the ship where the echoes will be picked up by the transducers. The data collected from each echo is presented visually to the science team.  When we reach a spot where a lot of the acoustic signals returning to the boat indicate the presence of fish, a trawl sample will be taken at that location. A trawl survey includes putting a large net into the water and scooping up a sample of all of the living things in that location. Once the trawl haul is brought onto the boat, it is taken to the fish lab where the fish are identified and measured.  

Fish Lab

The area being surveyed is the Eastern Bering Sea and for this study is divided up into 28 different transects have been mapped out and are spread 20 nautical miles apart.  We will start at northern point of the first transect and travel south until we reach the bottom of it. Once we reach the bottom of the first transect we will travel 20 nautical miles west to the southern tip of the second transect.  We will then travel north along this second transect until we reach the top and then travel the 20 nautical miles west until we reach transect 3. This will continue throughout my time on the ship, and on the 2 other legs of this journey.  On this first leg of the research cruise, the aim is to survey and sample from 16.3 of the transects which will total a journey of 2627 nautical miles on the transect lines.

According to the NOAA National Ocean Service Website, “A nautical mile is based on the circumference of the earth, and is equal to one minute of latitude. It is slightly more than a statute (land measured) mile (1 nautical mile = 1.1508 statute miles). Nautical miles are used for charting and navigating.”

It was a long trip getting to Dutch Harbor, Alaska, but it has already been worth it!  I am on the Island of Unalaska, which is a part of the Aleutian Islands of Alaska. The main port city is called Dutch Harbor, or commonly just “Dutch”.  This is such a beautiful place that I probably never would have seen otherwise. There are mountains filled with grasses, berry bushes, and wild orchids as well as snow-topped peaks and natural waterfalls.  There are bald eagles everywhere and foxes that are so fluffy they almost appear to be dogs from far away. Looking into the water you can see a few scattered otters floating on their backs and the occasional harbor seal.

 

OSI Morning photo

This photo was taken from the bow of NOAA ship Oscar Dyson at port in Dutch Harbor, AK.


As soon as I landed in Dutch, I was greeted by two of the scientists that I will be working with, Matthew and Sarah.  They took me to NOAA Ship Oscar Dyson to drop off my luggage before we all went out to dinner.  I was pleasantly surprised to find out that I actually had my own stateroom.  Due to the number of female scientists and us being on the same work shift, we were both able to have our own rooms.  The rooms are so much nicer than I had anticipated them to be! The mattresses are comfortable, I have a desk space, there’s a television (that I will probably never watch) and I have my own bathroom as well.  

      

After we had dinner and returned to the ship, I went on a mini hike with one of the members of the science team and we went to view this amazing natural waterfall.  You wouldn’t know it was there if you weren’t looking for it. There is so much more that you can do when the sun is up for most of the day. At 11:30pm (the latest i’ve stayed up so far) it is still light outside.  There are so many clouds that the sky looks pretty grey, and there are a ton of clouds, often hiding the tops of the mountain peaks.

The next morning I woke up and went for a nice long walk along Captain’s Bay and sat and had coffee on the rocks and just admired the incredible view.  It is so much more beautiful here than I had imagined. Later a few of us went for a drive around the island and a few people surfed in the ocean, but I wasn’t brave enough to get in the cold water this time.

Since we will be on the ship for a while (23 days) we stopped at the grocery store to bring a few things onboard that we want to have in addition to our regular meals prepared on the ship by the stewards.  I decided that I wanted to bring some fresh fruit, not realizing that I would be paying way more than I expected for them! Everything is expensive here!

Personal Introduction:

Hello! My name is Lacee Sherman and I am pleased to have you join me on my Alaskan Research Adventure by following along on my blog.  I am currently the 7th Grade Science teacher at Firebaugh Middle School in Firebaugh, CA.  As I write this, I am just completing my fourth year of teaching middle school science.  I got my Bachelor’s Degree in Natural Science with a Biology Emphasis from California State University, Fresno.  I also got my single subject teaching credential in Science from Fresno State.

Ever since I can remember, science has always captivated me in a way that no other subject was able to.  I love the scientific process and finding creative solutions to problems and even still, always wanting to learn more.  There is something so special about being able to investigate something new in order to learn more about it.  There is so much in this world to be curious about.

My first taste of an authentic research experience came to me during my last year of Undergraduate education at Fresno State when a professor whom I admire, Dr. David Andrews, encouraged me to participate in the STAR (STEM Teachers as Researchers) program.  The STAR program allows individuals that are going to pursue STEM teaching the opportunity to participate in summer research at different Universities or National Labs for up to three summers.  Through this program I met people in the STEM field that have encouraged me and become lifelong Mentors.

My first summer, I spent working in the research lab of Dr. Brian Tsukimura at Fresno State helping to establish a protocol for quantifying vitellin concentrations in the California Ridgeback Shrimp.

My second and third summers in STAR were spent working with Ben R. Miller at NOAA in Boulder, Colorado as a part of the Global Monitoring Division (GMD).  I would look at data collected at different sites in the United States and help to create visuals to represent the quantities of different types of ozone depleting substances.

As a member of the STAR Program I was introduced to the 100Kin10 initiative which is working towards adding and retaining 100,000 excellent STEM teachers into the profession within a 10 year time span.  I am proud to be one of the 100Kin10 educators and I am also a member of the Teacher Forum that helps to provide valuable input from a teacher perspective to the partners working to improve the future of STEM Education.

Personal Log

In less than a week’s time I will be boarding NOAA Ship Oscar Dyson to participate in research on the Eastern Bering Sea off of the coast of Alaska.  I am so excited to meet all of the scientists and crew aboard the research ship and experience what it is life to live on board and work on research at the same time.  I love getting to jump back into the scientific community and remind my students that I am not just a teacher; I’m a scientist, too.  This research experience will help me to plan more hands on, research-based, and innovative lessons for my students.

I have never been to Alaska and I cannot wait to see the natural beauty and I want to see all of the wildlife that I can.  I am looking forward to being able to share my knowledge and experiences with family, friends, and my students through this blog.
