Third Wire FS70

The Third Wire FS70 provides an image of the net, shown as half circle, and the fish around it.

The big news is that we’re headed to port a day early. There was a electrical component failure in the engine system that converts the diesel power to electricity which powers the electrical motors that turn the propeller shaft. This reduced the Shimada to running on about half power. I can’t believe the cruise is ending!

Yesterday we did a bottom trawl, the first bottom trawl ever conducted on the Shimada. Using the sonars, the scientists on the sonar team saw an interesting aggregation of fish. They couldn’t use the usual mid-water net, which is relatively easy to damage, because the fish were very close to the bottom. Besides, the bottom appeared hard and rocky. I was excited when they decided to test the new net. Unlike the mid-water trawls, which usually bring up a mostly “clean” haul of hake, a bottom trawl tends to bring up a wide array of species. I wanted to learn some new names.

ITI

The ITI shows the distance of the bottom of the ocean from the net. Where the pink lines are highest, the net is lowest.

Deploying the bottom net proved educational. The mid-water net is sent down with the FS70 attached, which provides an image of the objects near and in the net. On the screen shot of the FS70 above and to the right, look for the half-circle, which shows the open net, the silver blue line under the net, which is the bottom of the ocean, and some dots inside the net that are most likely fish already caught in the net. The images are sent through a wire. It would be too easy to damage the wire in a bottom trawl, so the scientists use the ITI instead.

Larry was in charge of fishing today and was disatisfied with the image the ITI System produced of the bottom trawl. The ITI does not produce as good an image of the bottom trawl as the FS 70 did on the midwater trawl. This made it more difficult to decide how much was being caught and how long to fish. The scientists began planning how to get a better system for the ship.

The bottom trawl disappointed the scientists because it brought up fewer hake than they had hoped, but I was happy to see so many new kinds of fish, and to learn to identify many so that I could help sort. This is the list of everything we pulled up:

Ratfish

Personal Log

Last night, some of us went up to the fly bridge in hopes of seeing the Perseid Meteor Shower. The sky was miraculously clear but the nearly full moon and bright lights on the ship blocked out most of the stars. Still, we saw some truly magnificent shooting stars before the clouds rolled in. I had brought my sleeping bag for warmth and fell fast asleep to the soothing voices of my shipmates. When they woke me up, I dropped by the chemistry lab to see how the nighttime zooplankton sampling was going and discovered that a mallard had arrived on deck. Mallards are not sea birds and are not equipped to be so far out to sea, so we were highly surprised to see her some fifty nautical miles off land. We named her Myrtle. We gave Myrtle food and water and hoped she would stay with the ship until we were close to land, but after a long nap, she took off. I hope she makes it to land.

In cribbage news, I won the semi-finals but lost the championship game. I had such a great time playing.

Mola Mola

A mola mola, like the one I saw from deck.

Today the ocean was crystal clear and the sky partly clear. I saw amazing creatures floating on the still surface of the water — salps, mola mola, and jellies. Mola mola, also called sun fish, are flat and float on the surface of the water, seeming to sun themselves, eating jellyfish. The water was speckled with salps, identifiable by their small, jelly-like bodies and dark center. When Jennifer saw the salps, she groaned, explaining that their presence suggests a relaxation in the winds that drive upwelling. Less upwelling means fewer nutrients for the whole marine system. I spent the whole day trying to wrap my head around the fact that the slight winds I feel every day drive such an enormous system as coastal upwelling, and that one peaceful day could cause so many salps to be floating on the surface.

Black-footed albatross, like the one I saw

Black-footed albatross, like the one I saw

Usually there are enormous black-footed albatross all around the ship. Albatross, one of the biggest birds in the world, spend most of their lives at sea, coming to shore only to breed. The albatross I see may be nesting on remote Pacific islands, traveling many days to gorge themselves on fish off the West Coast before returning to their nests. They come to our waters because of all the fish here due to upwelling. An albatross can be away from the nest as many as seven days, returning to regurgitate fish from its stomach, which the chicks will eat. Like many seabirds, albatross fly extremely efficiently. They rise and sink repeatedly as they fly to use the energy from the wind. They also use the rising air that comes off of waves for more lift. I see them soaring without moving their wings, so close to the water that they disappear from view behind small waves. Before flapping, they seem to tilt upward, and even so, their wings appear to skim the water. A windless day like today is a hard day for an albatross to fly, so they stay on the water. I saw very few, all in grounded groups.

Tufted Puffin

Tufted Puffin

Instead of albatross, I saw many small diving birds, especially when we came close to the beautiful, jagged coast of the Quillayutte River and La Push, Washington. I saw tufted puffins in bright breeding plumage, surfacing on the water for a few minutes before bobbing back under for surprisingly long times. The day before we set sail, Shelby and I visited the Newport Aquarium, where we saw tufted puffins in the arboretum. We saw the puffins swim through the water in the arboretum, wings flapping as if they were flying. We told a volunteer we were headed to sea. She said to look for single puffins close to shore. This time of year, puffins are nesting in pairs, making nests in burrows in cliff faces this time of year. While one puffin stays in the nest, its mate goes to sea, eats its fill of fish, stuffs about another seven fish in its beak, and returns to feed its chicks. The puffins I saw certainly looked like they were hard at work hunting for fish.

Deploying the Tow Fish

Deploying the Tow Fish

Today I helped deploy two sonar devices that I haven’t seen before, a sub-bottom profiler called a tow fish, and an Expendable Bathythermograph (XBT). The tow fish is a sub-bottom profiler, meaning that it sends a signal to map the bottom of the ocean. The scientists on the acoustics team are using it to look for fish. We backtracked over a section where we fished yesterday and dragged the tow fish alongside the ship. The data from the tow fish will be analyzed later, and proofed against the information from the haul and the other sonars. As usual, the goal is to be able to use the data to identify specifies with more and more accuracy.

XBT

Alicia showing me how to launch the XBT

The XBT is a probe that measures the temperature of the water. Falling at a known rate, it sends the temperature back through two small copper wires, which can be graphed as a function of temperature vs. depth in order to find the temperature profile of the water. Because the XBT looks vaguely like a gun, Larry left earplugs and a mask out for me, warning me about the explosion I was about to make. However, Alicia was in charge. She said, “There’s a hazing that happens with the XBT. I’m a bad liar. You don’t need this stuff.” So I went out on deck in just a life jacket and hardhat, which are required when doing any operation on deck. Once the technology tech radioed that the XBT had fallen to the necessary depth, I broke the copper wires. They were so thin I could cut them by rubbing them between my fingers.

Shelby

Shelby taking algae samples

Shelby, my roommate and a student Western Washington University, showed me her work measuring harmful algal blooms (HAB). While algae and other phytoplankton are essential to marine ecosystem because as primary producers, some algae produce domoic acid. Domoic acid is toxic to marine life and humans. Using surface water collected outside the boat and pumped into a hose in the chemistry lab, Shelby filters the water and saves the filter paper for further analysis of domoic acid and chlorophyll. A NOAA scientist will compile her data in an effort to map HAB along the West Coast. Shelby is a volunteer, one of four college students who each collect the data for one leg of the journey.

Fish Prints

Rebecca teaching me to make fish prints from the yellow-tails we had caught

Life aboard the Shimada seems to suit me very well. Every time I ask a question, which is often, I learn something new, and every time I look outside, I see something I never saw before. Yesterday, I ran into Rebecca in a hallway. Excited, she said, “There’s a P3 about to launch a sonobuoy!” I asked her to repeat. She said, “There’s a P3 about to launch a sonobuoy!” I stared at her. She said, “A plane is dropping stuff. Go outside and watch.” We both had to laugh about that one. Outside, I quickly learned that a marine ship had called the bridge to ask if we would help with a mission to drop a sonobuoy. A sonobuoy is a  listening device. With a parachute attached, it drifts into the ocean, where it floats, using passive sonar to report the location of objects like submarines. The day was shockingly beautiful, so a number of us stood on the very top deck of the ship, called the fly bridge or, jokingly, the beach. We watched the airplane circling us and watched the drifting clouds and diving birds. Several people declared it the flattest water they had ever seen in these parts.

I am happy to say that, with beginner’s luck, I won the first match of cribbage, placing me in semi-finals, and have started staying up in the evenings playing cards with other people on board.

On the fish deck in my work clothes

On the fish deck in my work clothes

The Shimada conducts research around the clock, with crew members working twelve-hour shifts. So far, I have worked with the acoustics team studying hake during the day, when the hake school together and are easy to fish. Last night I branched out, staying up with Steve Pierce, the oceanographer studying ocean currents, Jennifer Fisher, a faculty assistant at Oregon State University (OSU) who is studying zooplankton, and her intern, Angie Johnson, a graduate student at OSU. All the different research on this trip complements each other, and I learned more about the acoustic team’s work from the night people.

Gray's Harbor Transects

Gray's Harbor Transects

The map at right shows the transects we follow and the stations that the night team takes samples, which Steve chooses. Just like the acoustics team, he only chooses sites on the east-west transects. The night team usually works one transect ahead of the day team, and must have the ship back where they started by sun-up. Steve is mapping small currents because, he says, surprisingly little is known about ocean currents, even though they have a tremendous impact on ocean life.

He is especially interested in the polar undercurrent that brings nutrient-rich water from the south up along the west coast. A small current, it is nonetheless important because of the nutrients it carries, which come to the surface through upwelling. He uses an acoustic device, the Acoustic Doppler Current Profile (ADCP), to find the velocity of the water at various depths. The data from the ADCP is skewed by many factors, especially the velocity of the ship. Later, Steve will use trigonometry to calculate the true velocity. He also uses the Conductivity, Temperature, Depth (CTD) meter, lowered into the water at every station during the night. The CTD gives much more information than its name would suggest, including salinity, density, and oxygen. It is deployed with a high-speed camera and holds bottles to capture water samples. I was impressed by the amount of work – and math! – that Steve does in between cruises. When he has down time on this cruise, he told me, he is calculating work from two years ago.

Jennifer and Angie are studying plankton, the organisms at the very bottom of the food web. Immediately, I recognized euphausiids, or krill, from the contents of hake stomachs. Actually I recognized their small black eyes, which always reminded me of poppy seeds when I saw them in hake stomachs. Jennifer is conducting this work through her group Northwest Fisheries Science Center, which, as she describes it, gives her a wonderful freedom to research different projects related to ocean conditions, especially salmon returns. In this project, they measuring phytoplankton, tiny, photosynthetic organisms, by measuring chlorophyll and nutrients. They are also looking at zooplankton, like euphausiids, salps, and crab larvae, which we examined other the microscope. To help the acoustics team refine their ability to use sonar to identify zooplankton, Jennifer and Angie record certain species. The acoustics team will match up the acoustics data that is continuously generated on this ship with the samples.

Today, the second catch of the day was aborted because of whales too close to the ship. However, the NOAA’s Pacific Marine Environmental Laboratory (PMEL), had asked the Shimada to investigate its waveglider. A waveglider is type of robot called an autonomous underwater vehicle (AUV). Programmed to travel and record data, it does not need an operator. The PMEL folks were concerned, however, that its AUV might have a problem.The bridge set the course for the AUV, described as a yellow surfboard, and I headed up to the flying deck, the highest deck and an ideal spot for observation, to watch for it. Immediately we saw a humpback whale, just starboard of the ship, spout and roll through the water, its tail raised in the air. Soon the AUV appeared. We saw nothing wrong with it but communicated our observations, photographs, and video tape of it to PMEL. The PMEL’s system of wavegliders monitor carbon dioxide levels and use the kinetic energy of ocean waves to recharge the batteries. The acoustics team hopes to get their own waveglider next year to collect acoustic data in between transects. As I was peering  over the edge of the boat, examining the surfboard-like robot below, I heard a loud splash. A bout ten  Dall’s porpoises were playing around the bow of our boat, rippling in and out of the water. Dall’s porpoises are tremendously playful creatures, and will often play around ships. But our ship was barely moving, and the porpoises soon lost interest and swam away.

Personal Log

I’m getting a little of everything on this cruise. I would have stayed up two nights ago for the deploymentof the CTD and zooplankton samples, but the propeller developed a loud enough whamming sound to suspend all operations indefinitely. I woke up at 4:00 AM yesterday because the boat was swaying back and forth violently. (Violently by my standards, that is; more experienced mariners insist the swell is nothing.) Since our bunks go port to starboard, I could feel my weight sliding from hip to head to hip to head as I was rocked back and forth in bed. Meanwhile a discarded lightbulb in a metal shelf was rolling back and forth steadily – rattle-rattle-WACK! rattle-rattle-WACK! – until Shelby Herber, a student at Western University and my roommate, got up, found the culprit, and wrapped it in a shirt. When I woke again, it was eleven hours after the discovery of the problem with the prop and well past breakfast, and I started to get up until Shelby told me we were off transect, headed to shore because of the propeller.

So we took our time getting up. But when I finally arrived in the acoustics lab, Rebecca was running up the hall, saying, “Caitlin, I was looking for you! There’s a great big shark outside, and we’re pulling up the ROV!” The ROV is the remotely controlled vehicle, a robot like the AUV, but one that requires an operator to make it move. Unfortunately, out on the fish deck, the ROV was being put away and the shark gone off on his fishy business. To console me, John had the videotaped footage from the ROV and the dorsal fin of the shark, and showed me both. The ROV revealed no damage and I was invited down to the winch room, where the bang-bang-bang coming from the propeller was unnerving.

Everyone was in an uproar trying to decide what to do, an uproar made all the more dramatic by the steady lurching and swaying of the ship, which throughout the day has sent most of the scientists to their room for at least a few hours and most of the deck hands to tell stories of unhappy tourists who couldn’t find their sea legs. Finally, the engine guys decided the warped propeller would not prevent us from getting to Port Angeles, and Rebecca decided it would not interfere with the acoustics, and we got back on transect.

I’m getting a little bit of everything on this cruise. I’ve seen sharks and marines mammals, calm seas and rockier seas, an impressively well-functioning ship and a number of technological problems. I’ve interviewed scientists, NOAA Corps officers who command the ship, and crew members who recount endless adventures at sea. I’m even signed up for the cribbage tournament, which I’m not entirely thrilled about since I don’t know how to play bridge. I’ve been impressed by how much time and information everyone seems to have for me. I am constantly thinking how I can bring this experience back to my students. Some ideas are to have a science and math career day, collect weather data like the data the bridge collects, dissect hake, and examine zooplankton under a microscope. Various people on board have volunteered to help with all my ideas.

Shimada

Me in front of the Shimada.

Yesterday, I saw, sexed, and measured my first hake. And my second hake, and hundredth hake, and two hundredth hake. Most of the time, the scientists on the acoustics team watch computer monitors that show acoustic data as colors to represent life under the ship. Twice today, however, they identified large populations of hake and decided to fish for them in order to get more accurate data.

Pressure Housing

The pressure housing, held together by electrical tape and sponges, holds the battery and data storage for the light, lasers, and camera attached to the net.

Both times, the ship went into immediate action. Upstairs in the bridge, or command room, the NOAA officers slowed and repositioned the ship. Two scientists watched for marine mammals. If mammals were too close, we would have to abort the operation entirely. On the fish deck, John Pohl, on the acoustics team, taught me to assemble the pressure housing and attach it to the net. Objects attached to the net include the video camera, which will film anything passing by the mouth of the net, a four-beam laser to judge the length of the images that are filmed, a light to illuminate the water, batteries for power, and another camera for storing the data. The crew began lowering the net.

Hake

Josh Gunter, survey technician, operates a hatch to let hake onto the flow cale, which will find the mass of the whole haul.

For me, the real excitement began once the fish began pouring onto a conveyor belt into the fish lab. First, we sorted the fish by species. In the first haul, the fish were mostly hake, as intended, but we also caught three yellow-tail rockfish and three eulachons, a type of smelt. In the second haul, there was largely yellow-tail rockfish and hake, with several Pacific Ocean perch and widow rockfish. The rockfish were difficult to sort: they have dangerous spines and fight hard. Alicia Billings, a fisheries biologist on the acoustics team, taught me how to pick them up with one hand over their eyes and the other firmly grasping their tails. Even so, we both had a few close calls. We threw most of the fish right back into the ocean but kept about three hundred hake to sex and scale. With another fifty hake, we put then stomachs in individual bags so that the lab on shore can determine what the hake were eating. We also stored the otolith, or ear bones, in order to determine the age of the hake. Just like the rings of a tree, otoliths show growth rings every year.

Fish Lab

In the wet lab, the acoustics team prepares for the next batch of hake. From left Alicia Billings, Steven de Blois, and Dr. Rebecca Thomas

Finally, we cleaned up and settled back in the acoustics lab to watch for the next batch of fish.

The monitors use echosounders, which are exactly how they sound: Signals (sound waves) are emitted from beneath the ship and echo back once they hit something. The computer records the distance of an object by how long it takes for the signal to return.  For example, suppose a fish were right at the surface. The signal would hit it and return in very little time.

Echosounder

The monitor shows the depth of the ocean floor, sea surface, and objects in between.

On the other hand, in deep water the signal would take much longer to hit the bottom of the ocean and return. See the thick red line on the graph to the left? That’s the ocean floor. Notice how it curves down on the right at the edge of the continental shelf. The flat line at the top of the graph is the surface of the ocean. The scattered dots in between are most likely fish. The scientists can guess the kind of fish and the number of fish by the pattern and color of dots. All the color below the ocean floor is meaningless noise. Look to the upper left-hand corner of the graph to find the frequency of the signal, measured in kilohertz (KHz). The lower frequencies (20 kHz and 38 kHz) tend to measure larger objects and to go deeper in the water. These frequencies are perfect for finding hake. The higher frequencies (120 kHz and 200 kHz) measure smaller objects. For example, shortly before we started the first haul, we saw a large number of plankton, which showed up bright blue on the 120 kHz and 200 kHz frequencies but barely showed at all on the lower frequencies.

You can follow the progress of the Shimada at shiptracker. We’re headed for Port Angeles on August 14, making East-West transects along the way.

Personal Log

I am so happy to be at sea. The journey was delayed an entire day because of a problem with a valve, and we finally set sail yesterday. The skies are blue and the ocean calm, and I am constantly learning new stuff. I’ve had to learn to lift my feet when stepping through a doorway (I forgot once and went sprawling!) and to memorize the complicated series of halls and ladders to get from the fly deck to the bridge to the mess room to my stateroom. I’ve had to memorize thirty-some names.  The scientists have been incredibly patient, explaining each part of their work while I take copious notes. Working in the fish lab is my favorite part so far. It’s fascinating and satisfying work.

I am impressed by the sense of camaraderie on this ship. The scientists on the acoustics team – also known as the hake people –  keep up a constant, teasing banter, which only turns serious when discussing science. With science, they all have a different opinions. Before fishing today, Chief Scientist Larry Hufnagle worried that there were too few fish shown on the monitor. He said, “I don’t even know how you would fish on this stuff.” Dr. Rebecca Thomas, a research fishery biologist on the acoustics team, seemed to think there were plenty of fish, but suggested leaving the net in for a longer amount of time for a larger sample. After much more discussion, the team decided on a strategy and put in the net. I’m impressed how often they disagree and how carefully they listen to one another’s ideas.

Bell M.  Shimada

NOAA Ship Bell M. Shimada

This Sunday, I’m headed off to sea! The mission of my cruise is to survey Pacific hake (also called Pacific whiting) populations. Hake is a species of fish that supports a huge fishery off the West Coast. As it states on NOAA’s Fishwatch website, “The Pacific whiting (hake) fishery is one of the largest in the United States. Pacific whiting is primarily made into surimi, a minced fish product used to make imitation crab and other products. Some whiting is also sold as fillets.” I’ll leave from Newport, Oregon, and arrive two weeks later in Port Angeles, Washington. The ship, the Bell M. Shimada, belongs to the National Oceanic and Atmospheric Administration (NOAA). I get to go on the Shimada because of NOAA’s program Teacher at Sea (TAS), which sends teachers aboard research vessels so that we can increase our scientific literacy and bring our new knowledge back to the classroom. I can’t wait. I’ve never even spent a night aboard a ship, so this whole journey will be new for me.

I teach seventh and eighth grade integrated science at Floyd Light Middle School, in the David Douglas School District, in Portland, Oregon. I earned my Master’s in Education at Portland State University and my Bachelor’s of Art in Environmental Science at Mills College, in Oakland, California. In between, I taught English at a public elementary school in Curico, Chile. I love science and I love teaching. As soon as I decided to become a teacher, I made up my mind to participate in TAS, because it will help me teach my students the importance and fun of science.

At a dragon boat race

When I’m not teaching, I paddle with a dragon boat team, spend time with friends and family, and ride my bicycle. I’m always looking for new projects and new things to learn. I’m lucky to live in a city as great as Portland, where there are always interesting events going on around town.
