Science and Technology Log

Today I completed my first shift on the science team and we surveyed 3 complete stations. At each station, we carried out a multi-step protocol (or procedure). Here are the steps:

IMG_1039

The Depth Contour Output graph displays data collected from one station.

Before we begin fishing, the ship conducts a transect (or cross-section) of the survey area, using multiple pieces of equipment to observe the ocean floor. This tells us if it is safe (for both ship operations and for fragile coral that may exist) to trawl here. If a coral reef or other large obstacle was present, we would see significant variation in the depth of the ocean floor. This “depth contour output” graph shows the data we collected at one station. How deep is the water at this station? Is it safe to trawl here?

IMG_1028

The CTD collects information about water chemistry

We also use a collection of instruments called a “CTD” to collect information about the chemistry of water itself at different depths. This information is called the water’s “profile.” For fisheries studies, we are most interested in the amount of dissolved oxygen and the temperature at different depths. Why might this information be relevant for understanding the health of fish populations?

IMG_1025

Forel-Ule color scale

We also measure the water color using the Forel-Ule color scale by matching it to the samples shown in this photo. This gives scientists an indication of the amount of particulates, chlorophyll, and nutrients are in the water.

IMG_0033

Trawl Net being lowered into water

Once we determine it is safe to trawl, the ship returns to the starting location. We will trawl along the same path that we observed. Here’s the trawl net before it is lowered into the water. It will be pulled just along the bottom of the survey area, using tickler chains to agitate the ocean floor for benthic organisms for 30 minutes, and collecting whatever crosses its path!

IMG_1037

The catch is emptied into baskets

Once the trawl is finished, the deck crew uses a large crane to pull the trawl on board. We all help to empty the net and place everything into baskets. Most of what we catch are biological organisms, but small amounts of non-living material (like shells, dead coral, and even trash) come up as well.

IMG_1002

The Wet Lab

We then bring the baskets into the wet lab.

IMG_1046

Baskets are emptied into a long trough with a conveyor belt

We dump the baskets into a long metal trough that has a conveyor belt at the bottom.

IMG_1014

The catch is sorted into baskets by species

Next we sort the catch. Each species gets its own basket and we count the number of individuals for each species.

IMG_1032

Identifying organisms

Then, it’s time for the tough part (for me at least) – every organism has to be identified by its scientific name. That’s a lot of Latin! Fortunately, Andre and the senior scientists are very patient and happy to help those of us who are new. It’s amazing how many species these experienced scientists recognize off the top of their heads.

IMG_1030

Field Guides

We also have many field guides, which are books containing photos and descriptions of species, to help us.

IMG_1017

For each species, we record the total number of individuals and total mass

We are interested in how much of each species are present, so we record both the total number of individuals and total mass of each species.

IMG_1059

TAS Anna Levy measures the length of a flatfish using the Limnoterra Board

We also measure the length and mass of a sample of individuals. A handy device called a Limnoterra Electronic Measuring Board makes this process easy.  We place the mouth of the fish on one end of this board and then touch its tail fin with a pen-like magnetic wand. The board then automatically sends the fish’s length to the computer to be recorded.  We use an electronic balance that is also connected to the computer to measure and record mass.

IMG_1008

A computer screen displays FSCS software

All of the information is recorded in a database, using software called FSCS (pronounced “fiscus”).

Many of the specimens we collect are saved for use in further research on land.   Scientists at NOAA and other research institutions can request that we “bag and tag” species that they want. Those samples are then frozen and given to the scientists when we return to shore.

Any organisms or other material that remains is returned to the sea, where it can be eaten or continue its natural cycle through the ecosystem. The conveyor belt, conveniently, travels to a chute that empties back into the ocean. Now all that’s left is to clean the lab and wait for the process to begin again at the next station!

Our goal is to complete this process 48 times, at the 48 remaining stations, while at sea. 3 down, 45 to go!

Sometimes the work is high-paced…

This work has real highs and lows for me, personally. There are dramatic, hold your breath, moments like when equipment is lifted off the deck with cranes and lowered into the water. There is the excitement of anticipating what data or species we will find. My favorite moment is when we dump the buckets and all of the different species become visible. I’m amazed at the diversity and beauty of organisms that we continue to see. It reminds me of all of the stereotypical “under the sea” images you might see in a Disney movie.

The more challenging part is the pace of the work. Sometimes there are many different things going on, so it’s easy to keep busy and focus on learning new things, so time passes quickly. Other times, though, things get repetitive. For example, once we start entering all of the data about the individual fish, one person calls out the length and mass of a fish, while the other enters it into the computer – over and over until we’ve worked through all of the fish.

IMG_1050

… but sometimes the work even stops altogether, especially when whether interferes.

Sometimes, the work even stops altogether, especially when the weather interferes. There have been mild rainstorms coming and going continually. It is not safe to have people on deck to deploy the CTD and trawling equipment when there is lightning in the area, so there is nothing for the science team to do but wait during these times.

Because the pace of the work is constantly changing, it’s difficult to get into a groove, so I found myself getting really tired at the end of the shift. However, an important part of collecting data out in the field is being flexible and adapting to the surroundings. There is a lot to accomplish in a limited amount of time so I keep reminding myself to focus on the work and do my best to contribute!

Did You Know?

When working at sea, scientists must use special balances that are able to compensate for the movement of the ship in order to get accurate measurements of mass.

To ensure that we are accurately identifying species, we save 1 individual from each species caught at a randomly selected station. We will freeze those individuals and take them back to NOAA’s lab in Pascagoula, where other scientists will confirm that we identified the species correctly!

Questions to Consider:

Review: Look at the “depth contour output” graph above: How deep is the water at this station? Is it safe to trawl here?

Research: What does “CTD” stand for?

Research: For fisheries studies, we are most interested in the amount of dissolved oxygen and the temperature at different depths. Why might this information be relevant for understanding the health of fish populations?

Reflect: Why might scientists decide to use three different pieces of equipment to collect the same data about the ocean floor? And, why might they have several different scientists independently identify the species name of the same individuals?

Science and Technology Log: Nothing But Net!

Once the scientists determine where and how deep they want to fish, based on analyzing the echogram, then the boat moves into position and the net is deployed. Safety is the top priority when working on the vessel. The deckhands all have to wear life jackets, hard hats, and good boots when working on deck because the conditions can be sunny one moment and stormy the next.  There is some serious hardware at the back of boat. There are cranes, winches, and spools of wire ropes & chains. The Chief Boatswain is responsible for all deck operations and deploying any gear overboard. The following video illustrates the sampling process using an Aleutian Wing Trawl net.

There is a camera (aka camtrawl) attached to the net along with a small pocket net. The pocket net is designed to catch tiny animals that slip through the AWT meshes. The pocket mesh only catches a small amount of escaping animals which can then be used to determine what was in the water column with the bigger pollock. The camtrawl has a pair of cameras that shoot stereo images of what is entering the net. The camtrawl was developed by NOAA scientists and its goal is to estimate the size and identify the species that enter the net using visual recognition software from University of Washington. The ultimate goal of the camtrawl is to be able to identify everything entering the net without ever having to actually catch the fish.

A limitation of the AWT is that it can’t go closer than a few meters from the sea floor. Pollock are semi-pelagic so they are sometimes down at the sea floor and a different net is used. The Poly Nor’Easter (PNE) is used to trawl along the bottom of the Gulf of Alaska because the bottom can be rocky. The PNE has roller gear along its bottom to keep it from getting stuck. The opening of the PNE is 6 meters tall and 15 meters wide and also funnels to a codend.

There is a third net on Oscar Dyson called the Methot and it is used to catch large plankton such as krill. The Methot is so small that it sits on the deck and is easily lifted and put into the water. The net you use is determined by what you are trying to catch and where they are located in the water column.

Personal Log

Me in the survival suit.

I will admit that my biggest concern with going to sea was the thought of falling overboard. Now that I have been on Oscar Dyson I have learned that safety is a top priority and there are a lot of procedures for keeping everyone productive yet safe. Every week there are safety drills such as fire, abandon ship, and person overboard. The one I like the most is the abandon ship because I get to try on the survival suit. The waters here are so cold that survival overboard is unlikely without the survival suit.

It is comforting to know that the crew of Oscar Dyson work hard to keep themselves and everyone on board safe. I am no longer afraid of falling overboard because I’ve learned to be safe when navigating around the vessel and I have finally developed my sea legs – well sort of! The weather has been amazing with smooth sailing almost everyday. We did have a few days with some rolling seas and I had to put a seasickness patch behind my ear.

Science and Technology Log

Ahoy from the Bell Shimada! Today, I will explain three of the tools that are deployed from the side deck to obtain samples of the water and the ocean’s prey species.

First off we have the Harmful Algal Bloom Net, also known as the HAB Net, which is basically a 10-inch opening with a 39-inch fine mesh netting attached to a closed end canister. The HAB net is deployed manually by hand to the depth of 30 feet three consecutive times to obtain a water sample. The top fourth of the water collected is decanted and the remaining water (approximately 80ml) is transferred to a bottle which is then sealed and labeled with the location (latitude, longitude), date, time, vertical or horizontal position, and any particular comments. The samples will eventually be mailed off to California Department of Health Services lab for analysis for harmful toxins from algae that can affect shellfish consumers.

Next we have the hoop net, which is pretty much similar in design to the HAB net, except for a larger opening diameter of 3 feet (think hula hoop) and a net length of nine feet. The net tapers off into a closed container with open slits on the sides to allow for water drainage. The purpose of the hoop net to collect organisms that are found at the various depth levels of the deployment. The hoop net is attached to a cable held by the winch. The hoop net is lowered at a specific angle which when calculated with the speed of the vessel equates to a certain depth. The survey crew reports the wire angle sighting throughout the deployment.

Every time the hoop net is brought back up there is a sense of anticipation at what we will find once the canister is open. Coloring is a good indicator. Purple usually indicates a high concentration of doliolids, while a darker color may indicate a significant amount of krill. Phytoplankton usually have a brownish coloring. Many of the hoop net collections from today and yesterday include doliolids and colonial salps, neither are very nutrient dense. Yesterday we also found pyrosomes, which are transparent organisms that resemble a sea cucumber with little bumps and soft thorns along their body. The smallest pyrosome we came upon was two and a half inches with the largest over six inches long. A few small fish of less than one inch in length also showed up sporadically in these collections as well.

The Scientific team is looking for the presence of krill in the samples obtained. The Euphausia pacifica is one of the many species of krill found in these waters. Many tiny krill were found in the various hoop net deployments. On the last hoop net deployment for today and yesterday, larger sized krill of approximately 1 inch) were found. This is good news because krill is the dominant food source for marine mammals such as whales. Ideally it would be even better if the larger krill appeared more frequently in the hoop net samples.

Finally, we have the Tucker Trawl, which is the largest and most complex of the three nets discussed in today’s post. The Tucker Trawl consists of three separate nets, one for sampling at each depth: the top, middle, and bottom of the water column. Like the hoop net, the tucker trawl nets also have a canister with open slits along the side covered with mesh to allow water to drain. All three nets are mounted on the same frame attached to a wire cable held by the winch. As the Tucker Trawl is towed only one net is open at a time for a specific length of time. The net is closed by dropping a weight down along the tow. Once the weight reaches the net opening, it triggers the net to shut and sends a vibration signal up the cable line back to the surface which can be felt by the scientist holding the cable. The net is then towed at the next depth for ten minutes. Once the last net tow has been completed, the Tucker Trawl is brought back up to surface. Similar to the hoop net, the survey tech reads the wire angle throughout the deployment to determine the angle the cable needs to be at in order for the net to reach a certain depth. This is where all the Geometry comes in handy!

As mentioned already, with three nets, the Tucker Trawl yields three separate collections of the nutrients found within the top, middle and bottom of the water column. Once the nets are retrieved, each collection container is poured into a different bucket or tub, and then into a sieve before making it into a collection bottle. If there is a large quantity collected, a subsample is used to fill up a maximum of two bottles before the remainder is discarded back into the ocean. Once the samples are processed, an outside label is attached to the bottle and an interior label is dropped inside the bottle, formalin is added to preserve the sample organisms collected so that they can be analyzed later back in the lab.

Personal Log

It is so good to finally get my sea legs! I am glad I can be of use and actively participate. Cooperative teamwork is essential to getting everything to flow smoothly and on time. The Bell Shimada’s deck crew and NOAA team work hand in hand with the scientists to deploy and retrieve the various instruments and devices.

In the past two days I am getting a lot of hands on experience with deploying the HAB net to assisting with processing samples from the HOOP Net and Tucker Trawl. It’s always exciting to see what we might have collected. I can’t wait to see what the rest of the week may bring. I wonder what interesting finds we will get with the midnight Tucker Trawl samples.

Lesson Learned: Neatness and accuracy are imperative when labeling samples! Pre-planning and preparing labels ahead of time helps streamline the process once the samples are in hand.

Word of the Day:        Thermocline – This is the depth range where the temperature of the water drops steeply. The region above the thermocline has nutrient depleted waters and while the region below has nutrient rich waters.

Science and Technology Log:

Earlier today I had planned to write about all of the safety features on board the Bigelow and explain how safe they make me feel while I am on board.  However, that was before our first sampling station turned out to be a monster haul!  For most stations I have done so far, it takes about an hour from the time that the net comes back on board to the time that we are cleaning up the wetlab.  At station 381, it took us one minute shy of three hours! So explaining the EEBD and the EPIRB will have to wait so that I can describe the awesome sampling we did at station 381, Cashes Ledge.

This is a screen that shows the boats track around the Gulf of Maine.  The colored lines represent the sea floor as determined by the Olex multibeam.  This information will be stored year after year until we have a complete picture of the sea floor in this area!

This is a screen that shows the boats track around the Gulf of Maine. The colored lines represent the sea floor as determined by the Olex multibeam. This information will be stored year after year until we have a complete picture of the sea floor in this area!

Before I get to describing the actual catch, I want to give you an idea of all of the work that has to be done in the acoustics lab and on the bridge long before the net even gets into the water.

The bridge is the highest enclosed deck on the boat, and it is where the officers work to navigate the ship.  To this end, it is full of nautical charts, screens that give information about the ship’s location and speed, the engine, generators, other ships, radios for communication, weather data and other technical equipment.  After arriving at the latitude and longitude of each sampling station, the officer’s attention turns to the screen that displays information from the Olex Realtime Bathymetry Program, which collects data using a ME70 multibeam sonar device attached to bottom of the hull of the ship .

Traditionally, one of the biggest challenges in trawling has been getting the net caught on the bottom of the ocean.  This is often called getting ‘hung’ and it can happen when the net snags on a big rock, sunken debris, or anything else resting on the sea floor.  The consequences can range from losing a few minutes time working the net free, to tearing or even losing the net. The Olex data is extremely useful because it can essentially paint a picture of the sea floor to ensure that the net doesn’t encounter any obstacles.  Upon arrival at a site, the boat will cruise looking for a clear path that is about a mile long and 300 yards wide.  Only after finding a suitable spot will the net go into the water.

Check out this view of the seafloor.  On the upper half of the screen, there is a dark blue channel that goes between two brightly colored ridges.  That's where we dragged the net and caught all of the fish!

Check out this view of the seafloor. On the upper half of the screen, there is a dark blue channel that goes between two brightly colored ridges. We trawled right between the ridges and caught a lot of really big fish!

The ME70 Multibeam uses sound waves to determine the depth of the ocean at specific points.  It is similar to a simpler, single stream sonar in that it shoots a wave of sound down to the seafloor, waits for it to bounce back up to the ship and then calculates the distance the wave traveled based on the time and the speed of sound through the water, which depends on temperature.  The advantage to using the multibeam is that it shoots out 200 beams of sound at once instead of just one.  This means that with each ‘ping’, or burst of sound energy, we know the depth at many points under the ship instead of just one.  Considering that the multibeam pings at a rate of 2 Hertz to 0.5 Herts, which is once every 0.5 seconds to 2 seconds, that’s a lot of information about the sea floor contour!

This is what the nautical chart for Cashes Ledge looks like. The numbers represent depth in fathoms.  The light blue lines are contour lines.  The places where they are close together represent steep cliffs.  The red line represents the Bigelow’s track. You can see where we trawled as a short jag between the L and the E in the word Ledge

The stations that we sample are randomly selected by a computer program that was written by one of the scientists in the Northeast Fisheries Science Center, who happens to be on board this trip.  Just by chance, station number 381 was on Cashes Ledge, which is an underwater geographical feature that includes jagged cliffs and underwater mountains.  The area has been fished very little because all of the bottom features present many hazards for trawl nets.  In fact, it is currently a protected area, which means the commercial fishing isn’t allowed there.  As a research vessel, we have permission to sample there because we are working to collect data that will provide useful information for stock assessments.

My watch came on duty at noon, at which time the Bigelow was scouting out the bottom and looking for a spot to sample within 1 nautical mile of the latitude and longitude of station 381.  Shortly before 1pm, the CTD dropped and then the net went in the water.  By 1:30, the net was coming back on board the ship, and there was a buzz going around about how big the catch was predicted to be.  As it turns out, the catch was huge!  Once on board, the net empties into the checker, which is usually plenty big enough to hold everything.  This time though, it was overflowing with big, beautiful cod, pollock and haddock.  You can see that one of the deck crew is using a shovel to fill the orange baskets with fish so that they can be taken into the lab and sorted!

You can see the crew working to handling all of the fish we caught at Cashes Ledge.  How many different kinds of fish can you see?

At this point, I was standing at the conveyor belt, grabbing slippery fish as quickly as I could and sorting them into baskets.  Big haddock, little haddock, big cod, little cod, pollock, pollock, pollock.  As fast as I could sort, the fish kept coming!  Every basket in the lab was full and everyone was working at top speed to process fish so that we could empty the baskets and fill them up with more fish!  One of the things that was interesting to notice was the variation within each species.  When you see pictures of fish, or just a few fish at a time, they don’t look that different.  But looking at so many all at once, I really saw how some have brighter colors, or fatter bodies or bigger spots.  But only for a moment, because the fish just kept coming and coming and coming!

Finally, the fish were sorted and I headed to my station, where TK, the cutter that I have been working with, had already started processing some of the huge pollock that we had caught.  I helped him maneuver them up onto the lengthing board so that he could measure them and take samples, and we fell into a fish-measuring groove that lasted for two hours.  Grab a fish, take the length, print a label and put it on an envelope, slip the otolith into the envelope, examine the stomach contents, repeat.

Some of you have asked about the fish that we have seen and so here is a list of the species that we saw at just this one site:

  • Pollock
  • Haddock
  • Atlantic wolffish
  • Cod
  • Goosefish
  • Herring
  • Mackerel
  • Alewife
  • Acadian redfish
  • Alligator fish
  • White hake
  • Red hake
  • American plaice
  • Little skate
  • American lobster
  • Sea raven
  • Thorny skate
  • Red deepsea crab

 

 

 

 

I think it’s human nature to try to draw conclusions about what we see and do.  If all we knew about the state of our fish populations was based on the data from this one catch, then we might conclude that there are tons of healthy fish stocks in the sea.  However, I know that this is just one small data point in a literal sea of data points and it cannot be considered independently of the others.  Just because this is data that I was able to see, touch and smell doesn’t give it any more validity than other data that I can only see as a point on a map or numbers on a screen.  Eventually, every measurement and sample will be compiled into reports, and it’s that big picture over a long period of time that will really allow give us a better understanding of the state of affairs in the ocean.

It seems like time is passing faster and faster on board the Bigelow.  I have been getting up each morning and doing a Hero’s Journey workout up on the flying bridge.  One of my shipmates let me borrow a book that is about all of the people who have died trying to climb Mount Washington.  Today I did laundry, and to quote Olaf, putting on my warm and clean sweatshirt fresh out of the dryer was like a warm hug!  I am getting to know the crew and learning how they all ended up here, working on a NOAA ship.  It’s tough to believe but a week from today, I will be wrapping up and getting ready to go back to school!

Science and Technology Log:

On board the Henry B. Bigelow we are working to complete the fourth and final leg of the spring bottom trawl survey. Since 1948, NOAA has sent ships along the east coast from Cape Hatteras to the Scotian Shelf to catch, identify, measure and collect the fish and invertebrates from the sea floor. Scientists and fishermen use this data to assess the health of the ocean and make management decisions about fish stocks.

What do you recognize on this chart?  Do you know where Derry, NH is on the map?

This is the area that we will be trawling. Each blue circle represents one of the sites that we will sample. We are covering a LOT of ground! Image courtesy of NOAA.

Today I am going to give you a rundown of the small role that I play in this process. I am on the noon to midnight watch with a crew of six other scientists, which means that we are responsible for processing everything caught in the giant trawl net on board during those hours. During the first three legs of the survey, the Bigelow has sampled over 300 sites. We are working to finish the survey by completing the remaining sites, which are scattered throughout Cape Cod Bay and the Gulf of Maine.  The data collected on this trip will be added to data from similar trips that NOAA has taken each spring for almost 60 years.  These huge sets of data allow scientists to track species that are dwindling, recovering, thriving or shifting habitats.

The CTD ready to deploy.

The CTD ready to deploy.

At each sampling station, the ship first drops a man-sized piece of equipment called a CTD to the sea floor. The CTD measures conductivity, temperature and depth, hence its name.  Using the conductivity measurement, the CTD software also calculates salinity, which is the amount of dissolved salt in the water.  It also has light sensors that are used to measure how much light is penetrating through the water.

While the CTD is in the water,  the deck crew prepares the trawl net and streams it from the back of the ship.  The net is towed by a set of hydraulic winches that are controlled by a sophisticated autotrawl system.  The system senses the tension on each trawl warp and will pay out or reel in cable to ensure that the net is fishing properly.

Once deployed, the net sinks to the bottom and the ship tows it for twenty minutes, which is a little more than one nautical mile. The mouth of the net is rectangular so that it can open up wide and catch the most fish.  The bottom edge of the mouth has something called a rockhopper sweep on it, which is made of a series of heavy disks that roll along the rocky bottom instead of getting hung up or tangled.  The top edge of the net has floats along it to hold it wide open.   There are sensors positioned throughout the net that send data back to the ship about the shape of the net’s mouth, the water temperature on the bottom, the amount of contact with the bottom, the speed of water through the net and the direction that the water is flowing through the net.  It is important that each tow is standardized like this so that the fish populations in the sample areas aren’t misrepresented by the catch.   For example, if the net was twisted or didn’t open properly, the catch might be very small, even in an area that is teaming with fish.

Do you think this is what trawl nets looked like in 1948?

This is what the net looks like when it is coming back on board. The deck hands are guiding the trawl warps onto the big black spools. The whole process is powered by two hydraulic winches.

After twenty minutes, the net is hauled back onto the boat using heavy-duty winches.  The science crew changes into brightly colored foul weather gear and heads to the wet lab, where we wait to see what we’ve caught in the net. The watch chief turns the music up and everyone goes to their station along a conveyor belt the transports the fish from outside on the deck to inside the lab. We sort the catch by species into baskets and buckets, working at a slow, comfortable pace when the catch is small, or at a rapid fire, breakneck speed when the catch is large.

If you guessed 'sponges', then you are correct!

This is the conveyor belt that transports the catch from the deck into the wetlab. The crew works to sort things into buckets. Do you know what these chunky yellow blobs that we caught this time are?

After that, the species and weight of each container is recorded into the Fisheries Scientific Computing System (FSCS), which is an amazing software system that allows our team of seven people to collect an enormous amount of data very quickly. Then we work in teams of two to process each fish at work stations using a barcode scanner, magnetic lengthing board, digital scale, fillet knives, tweezers, two touch screen monitors, a freshwater hose, scannable stickers, envelopes, baggies, jars and finally a conveyor belt that leads to a chute that returns the catch back to the ocean.  To picture what this looks like, imagine a grocery store checkout line crossed with an arcade crossed with a water park crossed with an operating room.  Add in some music playing from an ipod and it’s a pretty raucous scene!

The data that we collect for each fish varies.  At a bare minimum, we will measure the length of the fish, which is electronically transmitted into FSCS.  For some fish, we also record the weight, sex and stage of maturity.  This also often includes taking tissue samples and packaging them up so that they can be studied back at the lab.  Fortunately, for each fish, the FSCS screen automatically prompts us about which measurements need to be taken and samples need to be kept.  For some fish, we cut out and label a small piece of gonad or some scales.  We collect the otoliths, or ear bones from many fish.

It does not look this neat and tidy when we are working!

These are the work stations in the wet lab. The cutters stand on the left processing the fish, and the recorders stand on the right.These bones can be used to determine the age of each fish because they are made of rings of calcium carbonate that accumulate over time.

Most of the samples will got back to the Northeast Fisheries Science Center where they will be processed by NOAA scientists.  Some of them will go to other scientists from universities and other labs who have requested special sampling from the Bigelow.  It’s like we are working on a dozen different research projects all at once!

 

 

 

Something to Think About:

Below are two pictures that I took from the flying bridge as we departed from the Coast Guard Station in Boston. They were taken just moments apart from each other. Why do you think that the area in the first picture has been built up with beautiful skyscrapers while the area in the second picture is filled with shipping containers and industry? Which area do you think is more important to the city? Post your thoughts in the comment section below.

Rows of shipping containers. What do you think is inside them?

Downtown Boston.  Just a mile from the shipping containers.  Why do you think this area is so different from the previous picture?

Personal Log

Believe it or not, I actually feel very relaxed on board the Bigelow!  The food is excellent, my stateroom is comfortable and all I have to do is follow the instructions of the crew and the FSCS.  The internet is fast enough to occasionally check my email, but not fast enough to stream music or obsessively read articles I find on Twitter.  The gentle rocking of the boat is relaxing, and there is a constant supply of coffee and yogurt.  I have already read one whole book (Paper Towns by John Greene) and later tonight I will go to the onboard library and choose another.  That said, I do miss my family and my dog and I’m sure that in a few days I will start to miss my students too!

If the description above doesn’t make you want to consider volunteering on a NOAA cruise, maybe the radical outfits will.  On the left, you can see me trying on my Mustang Suit, which is designed to keep me safe in the unlikely event that the ship sinks.  On the right, you can see me in my stylish yellow foul weather pants.  They look even better when they are covered in sparkling fish scales!

Seriously, they keep me totally dry!

Seriously, do I look awesome, or what?

This is a Mustang Suit. If you owned one of these, where would you most like to wear it? Photo taken by IT Specialist Heidi Marotta.

That’s it for now!  What topics would you like to hear more about?  If you post your questions in the comment section below, I will try to answer them in my next blog post.

Part One of the Survey Trawl: Getting Ready to Fish

This is a picture of a pollock from our first trawl.

This is a picture of a pollock from our first trawl.

Today is my second day aboard the Oscar Dyson.  We are anxiously waiting for the echosounder (more information on echosounder follows) to send us a visual indication that a large abundance of fish is ready to be caught.  The point of the survey is to measure the abundance of Walleye Pollock throughout specific regions in the Bering Sea and manage the fisheries that harvest these fish for commercial use to process and sell across the world.  The Walleye Pollock are one of the largest populations of fish.  It is important to manage their populations due to over-fishing could cause a substantial decrease the species.  This would be detrimental to our ecosystem.  The food web [interconnecting food chains; i.e. Sun, plants or producers (algae), primary consumers, animals that eat plants (zooplankton), secondary consumers, animals that eat other animals (pollock), and decomposers, plants or animals that break down dead matter (bacteria)] could be altered and would cause a negative effect on other producers and consumers that depend on the pollock for food or maintain their population.

The main food source for young pollock is copepods, a very small marine animal (it looks like a grain of rice with handle bars).  They also eat zooplankton (animals in the plankton), crustaceans, and other bottom dwelling sea life.  On the weird side of the species, adult pollock are known to eat smaller pollock.  That’s right, they eat each other, otherwise known as cannibalism.  Pollock is one of the main food sources for young fur seal pups and other marine life in Alaskan waters.  Without the pollock, the food web would be greatly altered and not in a positive way.

How do we track the pollock?

Tracking begins in the acoustics lab.  Acoustics is the branch of science concerned with the properties of sound.  The acoustics lab on board the Oscar Dyson, is the main work room where scientists can monitor life in the ocean using an echosounder which measures how many fish there are with sound to track the walleye pollock’s location in the ocean.  They also use the ships’s GPS (Global Positioning System), a navigation system, to track the location of the NOAA vessel and trawl path.

Echo Sounder

Sonar Screen

What is sonar and how does it work? 

Sonar (sound ranging & navigation;  it’s a product of World War II) allows scientists to “see” things in the ocean using sound by measuring the amount of sound bouncing off of objects in the water.  On this survey, sonar images are displayed as colors on several computer monitors, which are used to see when fish are present and their abundance.  Strong echoes show up as red, and weak echoes are shown as white.  The greater the amount of sound reported by the sonar as red signals, the greater the amount of fish.

Echo Sonar Screen Showing the patterns of echos from the ocean.

Echo Sonar Screen Showing the patterns of echos from the ocean.

How does it work?  There is a piece of equipment attached to the bottom of the ship called the echosounder.  It sends pings (sound pulses) to the bottom of the ocean and measures how much sound bounces back to track possible fish locations.   The echo from the ocean floor shows up as a very strong red signal.   When echoes appear before the sound hits the ocean floor, this represents the ping colliding with an object in the water such as a fish.

The scientists monitor the echosounder signal so they can convey to the ships’s bridge and commanding officer to release the nets so that they can identify the animals reflecting the sound.  The net catches anything in its path such as jellyfish, star fish, crabs, snails, clams, and a variety of other fish species. Years of experience allows the NOAA scientists the ability to distinguish between the colors represented on the computer monitor and determine which markings represent pollock versus krill or other sea life.  We also measure the echoes at different frequencies and can tell whether we have located fish such as pollock, or smaller aquatic life (zooplankton). The red color shown on the sonar screen is also an indicator of pollock, which form dense schools.  The greater amount of red color shown on the sonar monitor, the better opportunity to we have to catch a larger sample of pollock.

The Science Team Wonderful group of people.

Once we have located the pollock and the net is ready, it is time to fish.  It is not as easy as you think, although the deck hands and surveyors make it look simple.  In order to survey the pollock, we have to trawl the ocean.  Depending on the sonar location of the pollock, the trawl can gather fish from the bottom of floor, middle level and/or surface of the ocean covering preplanned locations or coordinates. Note: Not all the fish caught are pollock.

The preplanned survey path is called transect lines with head due north for a certain distance. When the path turns at a 90 degree angle west (called cross-transect lines) and turns around another 90 degree angle heading back south again.  This is repeated numerous times over the course of each leg in order to cover a greater area of the ocean floor.  In my case we are navigating the Bering Sea.  My voyage, on the Oscar Dyson is actually the second leg of the survey, in which, scientists are trawling for walleye pollock.  There are a total of three legs planned covering a distance of approximately 6,200nmi (nautical miles, that is).

Trawling is where we release a large net into the sea located on the stern (the back of the boat).  Trawling is similar to herding sheep.  The fish swim into the net as the boat continues to move forward, eventually moving to the smaller end of the net.  Once the sonar screen (located on a computer monitor) shows that we have collected a large enough sample of pollock, the deck hands reel the net back on board the boat.

This is the stern of the boat where the trawl net gets released into the ocean.

We have caught the fish, now what?  Stay tuned for my exciting experience in the wet lab handling the pollock and other marine wild life.  It is most certainly an opportunity of a lifetime.

What an adventure!

I was lucky enough to spend a day exploring Dutch Harbor, Alaska before departing on the pollock survey across the Bering Sea. It took me three plane rides, several short lay-overs and and a car ride to get here, a total of 16 hours. There is a four hour time difference between Dutch Harbor and Dover, Delaware. It takes some getting used to, but definitely worth it. The sun sets shortly after 12:00 midnight and appears again around 5:00 in the morning. Going to sleep when it’s still daylight can be tricky. Thank goodness I have a curtain surrounding my bed. Speaking of the bed, it is extremely comfortable. It is one of those soft pillow top beds. Getting in and out of the top bunk can be challenging. I haven’t fallen yet.

My bed is the top bunk.

During my tour through the small town of Dutch Harbor, I have encountered very friendly residents and fishermen from around the world.  I was fortunate to see the U.S. Coast Guard ship Healy docked at the harbor. What a beautiful vessel.  Dutch Harbor has one full grocery store (Safeway) just like we have in Delaware, with the exception of some of the local Alaska food products like Alaska BBQ potato chips. They have a merchant store that sells a variety of items ranging from food, souvenirs, clothing, and hardware. They have three local restaurants and a mom and pop fast food establishment. One of the restaurants is located in the only local Inn the Aleutian hotel, which also includes a gift shop. Dutch Harbor is home to several major fisheries. Dutch Harbor is rich in history and is home to the native Aleutian tribe. I took a tour of their local museum. It was filled with the history and journey of the Aleutian people. While driving through town, I got a chance to see their elementary and high school. They both looked relatively new. Dutch Harbor is also home to our nation’s first Russian Orthodox Church. Alaska is our 50th state and was purchased from Russia in 1867.

One of the coolest parts of my tour was walking around the area known as the “spit”. The “spit” is located directly behind the airport. I’m told it is called the “spit” because the land and water are spitting distance in length and width. We walked along the shoreline and discovered hundreds of small snails gathered around the rocks. We also found hermit crabs, starfish, sea anemones, jellyfish, and red algae. We saw red colored water, which is a bloom or a population explosion of tiny algae that get so thick that they change the color of the water.

Another animal in abundance in Dutch Harbor is the bald eagle. There is practically one on every light post or tall structure. Often the bald eagles are perched in small groups. Watch out: if you walk too close to a nesting mother, she will come after you. They are massive, regal animals. I never get tired of watching them.

We had to watch our step, the snails were everywhere along the shoreline of the Spit.

Did You Know?

Did you know that Alaska’s United States Coast Guard vessel has the ability to break through sea ice? 

This is especially helpful if you want to study northern areas, which are often ice covered, in the winter, and to assist a smaller boat if it gets trapped in the ice.

Did you know that scientists set time to Greenwich Mean Time (GMT) which is the time in a place in England?

This reduces confusion (e.g. related to daylight savings, time zones) when the measurements are analyzed.

Kainoa Higgins: Preparing to Set Sail! June 15, 2014

NOAA Teacher at Sea

Kainoa Higgins

(Almost) Aboard the R/V Ocean Starr

June 18 – July 3, 2014

Mission: Juvenile Rockfish Survey

Geographical Area of Cruise: Pacific Coast

Date: June 15, 2014

Personal Log

Aloha from the great Pacific Northwest!  My name is Kainoa Higgins and although I was born and raised on the island of O’ahu, Hawai’i, I have spent the last 10 years calling Tacoma, Washington home.  I am incredibly excited to have been selected as a 2014 NOAA Teacher at Sea and can’t wait to climb aboard the R/V Ocean Starr in a matter of hours!  I will be participating in two legs of research during my two and half weeks on ship.

During the first leg, I will be assisting scientists with conducting a Juvenile Rockfish Survey as they examine groundfish populations off the coast of the Western Seaboard of the North America.  Though I have been attempting to get caught up to speed, I currently only understand the program at a general level.  There are many species of rockfish, all of which are commercially valuable, and keeping track of their populations and distributions is essential for conscious management.  Having spoken with my Chief Scientist for this leg, Ric Brodeur, on several occasions leading up to my departure, I understand that my job will entail any, some or all of the following: mammal/bird observational surveys and plankton analysis by day followed by sorting of trawled collections analysis of the catch in the wet lab by night.  I’ll be able to share more as the adventure unfolds.

In the second leg, I will connect with Laurie Weitkamp who will take over as chief scientist with a fresh research team and research focus.  In a recent e-mail Laurie explained that this leg will be “experimental”.  In short, we will be trying a variety of modifications to a marine mammal excluder device to see how it fishes and influences the catch.  I’m not sure, exactly, how the MMED is used, but I would be willing to take a guess at it’s purpose.  I imagine it has something to do with an attempt to maintain commercial fishing operations without the interruption of marine mammals (dolphins, porpoises, seals, whales, etc.) in close proximity.  Through some sort of “deflection”, its goal would also be reduce unintentional by-catch.  Once again, I’ll know more concretely a bit further down the road.  According to Laurie, in addition to help work up the catch, I will be helping with “marine mammal watch” before and during fishing.  Since we will use a surface trawl during the day, it is possible that we could catch a marine mammal (e.g., seals and dolphins). To minimize this risk, I will help serve as a lookout  before we set and when the trawl is out, and are required to immediately stop fishing if any are spotted nearby.  I look forward to spending some time on the bow scanning the horizon for marine mammals.

Plankton

A bit more about myself and the school I represent.  I grew up loving the ocean.  Much of my life as a child was spend in or around it.  Whether snorkeling, surfing or fishing my brother and I were raised to respect and appreciate all that the ocean had to offer.  After all, my name, Kainoa, means “free as the sea”.  There is a saying in the islands, Malama ‘aina, Malama i ke kai, meaning ‘to care for the land and care for the ocean’.  After graduating from Punahou School  in Honolulu, Hawaii I headed for the great Northwest to attend the University of Puget Sound.  I participated in Athletics, Lu’au, Senior Theatre Festival and even Greek Life.  I studied Biology and spent a semester abroad in Christchurch, New Zealand.  Even though I took Marine Biology in one of the most amazing diverse systems in the world, my favorite class had to be “The Diversity of Algae”.  It opened my eyes up to the beauty and importance of micro life for the first time.  This led to my passion for – and borderline obsession with – plankton.

After earning a Master’s in the Arts of Teaching from UPS, I began my career at the Tacoma School of the Arts teaching entry level biology.  After my second year, I was asked to join our recently founded sister school, the Tacoma Science and Math Institute (SAMI) located in Point Defiance Park on the North Tacoma peninsula.  SAMI  is built around a particular vision: we believe that students make the most of their learning when they take ownership of their education—when students intentionally choose to take on the challenge real learning entails. We further believe that this ownership most naturally develops within a learning community, encouraged by others who share that commitment.  We theme our curriculum around the math and science and emphasis the integration of disciplines and staff collaboration all the while perpetuating the pillars on which the schools were founded: community, empathy, thinking and balance.  SAMI has allowed me to pursue my passion for marine science.  We are a two minute walk to the waterfront which makes the learning opportunities for myself as students invaluable.  Between this field resource and collaborations with the University of Washington in the High School program and the University’s School of Oceanography I am in a position to offer my students a world-class learning experience.

I think it is important that teachers are always looking for opportunities to improve their practice and better educate themselves in ways that will better prepare their students for the world ahead of them.  The Teacher at Sea opportunity is an incredible way to engage myself as a life-long learner and will help me to better engage and inspire my students.  I look forward to designing and offering lessons derived from real-time science and experiences.  I am very grateful for this opportunity and can’t wait to share it with you.

See you soon,

Kainoa
