View from the flying bridge departing Woods Hole
Our departure from Woods Hole has been delayed a number of times due to several factors. We were scheduled to leave the dock on Monday at 2pm, but due to rough seas (8ft on Georges Bank—which was where we were planning to go first) and a crane that needed to be fixed our departure was rescheduled for Tuesday at 10am. On Tuesday, the crane was fixed, but then it was discovered that the ship’s engineering alarm system was not working properly, so our departure was delayed again for a few hours. The crew worked hard to get the ship off the dock and we departed at 1:15 on Tuesday. Yay! We were on our way to Georges Bank, which was about a 15 hour “steam,” or, trip.
The purpose of the NOAA Fisheries Atlantic surfclam and ocean quahog survey is to determine and keep track of the population of both species. This particular survey is done every three years. NOAA Fisheries surveys other species too, such as ground fish (cod, haddock, pollock, fluke), sea scallops, and northern shrimp. These species are surveyed more often—usually a couple of times each year. Atlantic surfclams and ocean quahogs are surveyed less often than other fished species because they do not grow as fast as other species. In fact, the ocean quahog can live for more than 150 years, but it only reaches about 6 inches across! In comparison, the sea scallop lives for only 10 to 15 years and reaches a size of 8 inches.
There are 27 people on board this cruise. Each person is assigned a watch, or shift, so that there are people working 24 hours a day. The work never stops! Seventeen people on board are members of the crew that are responsible for the operation and navigation of the ship, machinery operation and upkeep (crane, dredge, etc.), food preparation, general maintenance, and electronics operations and repair. There are a lot of things that need to happen to make things on a research ship run smoothly in order for the scientific work to happen!

Twelve people on board are part of the science team, including me, who collect the samples and record the data. We are split into two watches, the noon-midnight watch and the midnight-noon watch. We sort through the material in the dredge for the clams and the quahogs. We measure and weigh them as well as document the location where they are collected. Several members of the science team are volunteers.

Our delayed departure has given me a lot of time to talk to crew and to explore Woods Hole—which I have really enjoyed. I have learned a lot about the responsibilities of the different members of the crew and about the maritime industry, which is something that has always interested me. I was also able to visit the Woods Hole aquarium (twice!) and attend a talk given by crew from the R/V Knorr. The Woods Hole Oceanographic Institute operates the R/V Knorr and it was on this ship that the location of the wreck of the Titanic was located for the first time in 1985. Additionally, in 1977 scientists aboard this ship discovered hydrothermal vents on the ocean floor. And, lastly, I had time to go swimming in the Atlantic Ocean! The water was a bit warmer off the coast of Massachusetts than it is off the coast of Alaska…
Questions to Ponder
What is the difference between an ocean quahog and an Atlantic surfclam?

This morning is the first day that I have awoken on board the ship. It will be my first twelve-hour shift. The scientists work either from noon until midnight or from midnight to noon. Kevin, the chief scientist, has assigned me to the day shift. I am very happy about this! We suit up in our foul weather gear. Those who have done this before explain to me that it is easiest to slip on the black rubber boots and rain pants like a firefighter who just got a call might do. We eagerly wait for the winch to pull the catch out of the water. The net drops everything out on the table. When we receive word from the engineer that all is clear, I don a hardhat, and hop up on the table with a white board that lists the station, strata and tow. My shipmate, La Shaun, snaps a photo record of the catch. We stand around the table and begin the inventory. We are looking for sea scallops and any we find go into a big orange basket. Other species that we separate out include: red hake, monkfish, haddock, skate, and ocean pout. We measure the length of the fish that we have separated. I imagine how the data might be used by scientists back on land to indicate the health of that portion of the ocean. As soon as we finish the haul and clean up, it is time to do it all over again. Every third catch we count the number of starfish and cancer crabs. I am excited to hold sponges, sea urchins, and hermit crabs. I am surprised to learn that the sand dollars are red.
Scallops!
Once all the sea life on the table has been sorted, it is time to head to the wet lab. There, the buckets of animals are counted and measured. Two persons work at each table measuring the fish. The fish is laid flat against the scale and one scientist uses a magnetic tool to capture the length electronically. During one catch, Aaron and I measured the length of 37 skate. I am impressed by the knowledge of the scientists who can easily tell the difference between a winter skate and a little skate. I hope by the end of the trip, I will be able to do so as quickly as they can.
Personal Log
I hardly notice the rocking of the ship while we are working. I think I may be starting to get my sea legs. On this first day there is very little time in between stations, and there is no real down time. I have learned how to shuck a sea scallop and seen the anatomy of the animal for the first time. I had been promised that I would get to work hard out on the open ocean and I am not disappointed.
Question of the DayDo you know the shape of the sea scallop shell? If you open the shell of a sea scallop you can immediately tell if it is a male or a female. How?

Personal Log
I reported to the Woods Hole dock at 7:30 in the morning. The day was bright and sunny, with temperatures in the 70s. The sight of the ship docked next to the NOAA building was so exciting. I climbed on board and introduced myself to Captain Jimmy who showed me right to the galley and offered me a cup of coffee. He was so welcoming! The ship had arrived in port at about 5:00 am and the crew and scientists were working to get everything ready to go by noon. I was shown my room, which is meant for four persons and has two sets of bunk beds. The room is so much bigger than it appeared in the photographs I saw! I chose a lower bunk and stowed my duffel bag underneath the bed in a cubby that was designed just for that. As more of those traveling on the journey arrived, I was interested to find that five of us have ties to Maine. We gathered to hear a briefing on the research that we will be supporting while on board the ship. Did you know that the American Sea Scallop is the most valuable fishery in the United States? Then we went off to lunch in the galley. The cook, Paul, served us an amazing lentil soup and sandwiches. The galley is full of snacks, a fridge with ice cream, and milk juice, coffee and tea, all of which are available day and night. As we were eating, I felt the ship start to move. We were told our first station is about eight hours away. (A station is a place where we collect a sample of the sea life.) Away we go!
Question of the Day What is the reason that Woods Hole became the location on Cape Cod for ocean research?

Science and Technology Log
The trip is winding down and we will be in port in a few hours. I am writing this final log in the early hours of the morning of my last night shift. We will soon be approaching Cape Cod Canal, and our time of arrival into Woods Hole is scheduled for 9:30 this morning. On last night’s shift, we passed the time taking CTD measurements and logging the events. Unfortunately, no trawls were completed since we didn’t come upon a location with an abundance of fish. Tonight we began with a trawl. As with the last trawl, the majority of our catch was redfish. We also caught Atlantic herring, northern shrimp, anchovies, pearlsides, silver hake and red hake, short fin squid, several dogfish and a goosefish. The catch from the trawl was sorted by species, just as before. The individual species were weighed and measured. Again, we took a subsample of redfish which means that we took a portion of the total catch and measured each individual length. Additional information was again gathered on the herring including sex, maturity stage, and stomach contents, and then a subsample was frozen for age analysis back at the lab. The Fisheries Scientific Computer System (FSCS) system was used for entry of the biological data.
I was also able to interview a few more of the crewmembers on the ship. Commanding Officer Richard Wingrove (otherwise known as Captain) has worked his way up to his Commander position during his 17 years experience with NOAA. Richard has a degree in Marine Biology and has loved the ocean from the time he was a child. His extensive background experiences include being a satellite oceanographer for the NOAA Hurricane Center, working for the National Marine Sanctuary on oil spill cleanups, and serving the Peace Corps as a fisheries officer in Antigua. As commanding officer of the NOAA ship DELAWARE II, his job involves overseeing the entire ship, supervising officers, and safely completing missions. He claims the best part of his job is working with the crew, which he thinks of as his family at sea, although he admits it is still tough being away from his real family. As one can imagine, the job of commanding officer comes with a great amount of responsibility. Richard is in charge of a $12 1/2 million ship and a crew of 34 people. Pretty intimidating!

He has a great deal of fond memories and stories of rough seas, though he recalls one humorous incident in particular. He was once on board a ship off the coast of Alaska when the seas were 25-30 ft. It was so rough that all the crew could do was ride out the seas; the cooks weren’t even able to make a meal! On a dare from the other crew members, Richard tried jumping up to touch his back to the ceiling, but mistimed his jump and ended up being slammed to the floor when the ship descended quickly and the ceiling pushed him down. He was stunned, but otherwise okay. This legendary stunt is still spoken of amongst Richard’s seafaring friends. Richard recommends taking many classes in science and math if one is interested in commanding a ship.
Lead fisherman Pete Langlois has experienced a lot of rough weather during his six years at sea aboard NOAA ships. He has many responsibilities aboard the DELAWARE II. A lead fisherman splits a 24 hour shift with the boatswain, and their duties are to operate the machinery on deck, such as the nets, winches and crane. Pete is responsible for the fishermen’s and scientists’ safety on deck while machinery is operating. He also oversees the deployments and recoveries of scientific instruments such as the CTD sensor. Additional duties of a lead fisherman include general maintenance of the ship, such as loading and unloading stores and equipment. Mr. Langlois also serves as third mate of the ship. A third mate is in charge of the track lines of the ship and acts as a representative of the captain.
One of the first things that Pete recommends for future sailors is to try spending time aboard a ship to see if you like it. It is also necessary to get your Able Seaman Certificate which is issued by the U.S Coast Guard. One path to pursuing your career is through a maritime academy, such as the Massachusetts Maritime Academy. He claims there is a high demand for all positions aboard ships, and it is important to get experience at sea in order to get an Able Seamen or Captain’s license.

Personal Log
Although I am sad for the trip to be over, I am looking forward to returning home to my family, friends, and classroom and sharing my experience with them. This trip has been invaluable to me in so many ways. I have met many amazing people, I have participated in recording ocean data, and I have seen how much thought, effort and talent goes into a fisheries research vessel. I am fortunate to have completed 3 mid-water trawls while on board. Being able to see and touch the fish that we are studying was amazing. I gained hands-on knowledge and experience, and I began to see the species not as slimy and gross fish, but as a necessary tool for progressing our understanding of ocean species.
The crew of the DELAWARE II has been nothing but welcoming and accommodating to me. I appreciated all of their care, time and patience with me as I learned about life on board a scientific research ship. Their sincere good natures and the humorous spirits will always be remembered by me. I can now better understand the wisdom shared by our Chief Scientist, Bill Michaels, about how people and teamwork are to be greatly appreciated. People are such a large part of what make a job enjoyable. It is easy to see that the entire crew of the DELAWARE II enjoy their jobs and each other’s company. They make an unbelievably great team. Thanks to all of the crewmembers of the DELAWARE II. I will never forget you or my experiences on board. My students will surely benefit from my gained knowledge for years to come. Thanks again for sharing a slice of your lives with me. I’ve been inspired by all of you.

Science and Technology Log
On Sunday, the DELAWARE II steamed out of the Great Harbor. Our first stop was Cape Cod Bay, and then we continued to the Gulf on Maine. It’s great to be at sea! My first night on the night shift felt very productive to me. I worked with fisheries biologists Dr. Jech and Karen to rig up the monofilament (fishing line) so we could attach the copper spheres beneath the hull in order to complete calibrations of the acoustic system. As explained in an earlier log, calibrations are required for each survey to ensure data quality and to verify that the equipment is working properly. We were mostly successful, but a few events slowed our progress, such as having to reposition the ship because of fixed gear (lobster traps) in the water near us. Once we located the copper spheres in each of the remote-controlled downriggers in order to move the copper sphere in all directions within the beam. After we worked out all the bugs during the first calibration, the system worked smoothly for the two remaining frequency calibrations. When we finished, we disassembled the downriggers and put away the gear.
We finished our first shift by deploying a Conductivity-Temperature-Depth (CTD) sensor and keeping track of it in the Event Log book and computer program. A CTD is an instrument that is equipped with devices which measure the salinity and temperature of the water and the depth of the instrument. Connected to a cable and winch system, it is lowered into the water within meters of the ocean floor, all the while taking measurements and sending data to computers on deck. A profile of salinity and temperature is taken at the end of each transect, or path, that the ship makes and also before a trawl is completed.
TAS Jill Carpenter with two redfish caught with a mid-water trawl
Deploying a CTD is a joint effort on the part of the officers on the bridge, the fishermen and the scientists. Communication takes place via walkie-talkies to synchronize the deployment time. While the officers on the bridge maintain the location of the ship and watch out for traffic, the fishermen are deploying the CTD instrument and the scientists are logging the event, recording information such as time of deployment and the latitude and longitude of the deployment. My second night on the night shift was also very eventful. We had begun a series of transects, which basically means that the ship zigzags back and forth across the ocean in order to take CTD measurements and locate large schools of fish for the purpose of trawling, or catching fish for biological sampling. Twice during the night, in the middle of parallel transects, we completed trawls. The High Speed Midwater Rope Trawl (HSMRT) is a funnel-shaped net attached to wires, also known as trawl warps, which are spooled onto winches located on the aft deck of the ship. The HSMRT is used to collect biological samples. The decision on where to trawl rests with the scientists as they interpret acoustic data, so if the acoustic system shows that there is a large collection of objects (hopefully fish) below the surface, a trawl may be completed. Trawling is also a group effort between the officers, the fishermen, and the scientists. The net is set out and retrieved by the fishermen who control the depth of the net and monitor its performance. The officers on the bridge work with the fishermen during the trawl to ensure its success.
The catch from the trawls is sorted by species. Then the individual species are weighed and measured. The catch from our first trawl included redfish, Atlantic herring, lumpfish, and northern shrimp. We then took a subsample of redfish which means that we took a portion of the total catch and measured each individual length. Because herring is the primary focus of this survey, additional information was also gathered on this species including sex, maturity stage, and stomach contents, and then a subsample was frozen for age analysis back at the lab. The Fisheries Scientific Computer System (FSCS) system was used for entry of the biological data. This is done by using a stylus to press the buttons on the computer screen to enter the catch information. The scales used for weighing the fish and the measuring boards automatically send their information into the computer system. The data is saved and later will be analyzed by the National Marine Fisheries Service.

Personal Log
I apologize for not writing in a few days. As I predicted, the shift work is taking a bit of a toll on me, and I haven’t been sleeping well during the day due to slight seasickness. It is such a strange feeling to be lying in bed and rocking back and forth. Sometimes the boat pitched so much that my stomach got butterflies, just like when you ride a roller coaster and go down a steep hill. I had to keep getting up and sitting on one of the decks so I could see the horizon and get some fresh air. Our stateroom has no windows, so there is no way of telling what the conditions are outside. I had to laugh at myself when I went up to the bridge, expecting to see a ferocious storm and high sea swells, only to find blue skies and slightly choppy waters. A combination of Dramamine, ginger root tablets, and Saltine crackers also helped to calm my stomach.
This past night of sleeping (rather, day of sleeping) went much better. I seemed to be used to the motion of the ship, and I fell asleep right away. It helped to wedge myself in between the wall and my bag to keep from rocking back and forth so much. I feel rested and much more confident to handle the seas. It was forecasted that Hurricane Florence would make our ride a bit rough, though she is passing several hundred miles from our location and seas have been much calmer than expected, which is fine with me! Even so, I can now see why we had to spend time tying down equipment so it wouldn’t slide or roll. When the ship was docked, it was hard to imagine it moving so much to necessitate securing items so well, but the need was evident to me after this shift. Several times during the night, the ship rolled side to side so much that even heavy items fell over and off tables. The chairs we were sitting in kept sliding back and forth, and we had to hang on to the tables to keep from moving around! It was wild. I loved it! I tried to get a picture, but I had to hang on instead!
Removing otoliths (ear bones) from a redfish. Otoliths are used by scientists to age a fish.
I was proud of myself when we completed our trawls and I had to handle the fish. It was rather disturbing to see the eyes and stomachs of the fish bulge out because of the change in pressure. We had to be careful when picking up the redfish because of the prickly spines sticking out of their fins. I was a little apprehensive to feel the fish through my gloves, and I was very grossed out at the thought of picking up a slimy, dead fish, but I tried to put that aside so that I could be of some help, at least. The biologists I was working with jumped right in and weren’t squeamish at all. After all, this is part of their job and the focus of their research. I tried to be brave and handle the fish confidently and without shrieking just as they did, but I still looked a bit wimpy. The important thing, though, is that I tried something new and walked away with an invaluable learning experience. Cutting apart a herring to examine its insides was a little over my limit, but I tried it anyway and now I am glad that I did. I figured that it’s not every day that I have the chance to dissect a fish in the name of research.
I spoke with Mrs. Nelson the other day, and she said I have a bright group of fifth graders awaiting my return. I can’t wait to show all of you my pictures and share this incredible learning experience with you.
Question of the Day
When weighing fish on board the ship, it is necessary to “tare” the scale. This means that if a fish is being weighed in a bucket, we must first put the empty bucket on the scale, and then we need to reset the scale so it measures to zero kilograms. After that, we place the fish in the bucket and put it back on the scale.
Why do you think it is important for scientists to tare a scale when weighing objects that are in containers?
Today, the DELAWARE II left the port and steamed out into the waters of Vineyard Sound for the day. It was exciting to finally get underway. While out at sea, the AFTV underwent additional testing and troubleshooting. I was able to work the joystick which controls the video camera on the front of the AFTV and enter information into the Event Log program to document the beginning and end of the AFTV deployment. We steamed back to Woods Hole for the evening, and our scheduled time of departure is tomorrow at noon. Once we leave tomorrow, we should be out to sea for the remainder of the cruise. Additionally, I was able to interview two other members of the crew. The Chief Scientist aboard this mission is Fisheries Research Biologist Bill Michaels. He has worked for NOAA and been a chief scientist for 27 years. He started as a co-op student at the Northeast Fisheries Science Center. Bill’s parents knew he would grow up to be a scientist when they saw him spending his time collecting feathers and examining flowers as a six-year old. He has extensive training in marine and fisheries biology and has been in charge of the National Marine Fisheries acoustic program working on advanced sampling techniques for almost 10 years. Bill has logged over 2000 days at sea and has been a part of many different research boats in many different countries! Bill believes that by incorporating advanced technologies into cruise operations, we will be able to provide more accurate, cost-effective and timely scientific information in order to meet NOAA’s goals.
Mr. Michaels says the best parts about his job are the diversity associated with the work and the teamwork involved. Because of these, he has enjoyed every day of his career. Although he loves working with new technologies such as his new Advanced Fisheries Towed Vehicle, he has come to enjoy working with people more and more, especially with scientists from other countries. Bill shared with me that he once went overboard during winter temperatures, though he wouldn’t say if it was by accident or on purpose! Some of his more challenging voyage experiences include being out to sea with 25 ft waves, having to sleep in a fish bin, and being on a foreign boat that was infested with cockroaches. Bill’s advice to someone who would like to become a scientist is to focus on all subjects, not just biology and math. He says that you can’t be a good biologist by studying only biology. He advises future biologists to understand people, value teamwork, appreciate different cultures, learn new technologies, and study from a variety of disciplines, ranging from geology to English and foreign languages.
TAS Jill Carpenter (far right) with NOAA Program and Management specialist Jeannine Cody, Chief Scientist Bill Michaels, and Fisheries Biologist Karen Bolles on board
I also spoke with my roommate and NOAA Program and Management Analyst, Jeannine Cody. She works in the National Marine Fisheries Service (NMFS) Office of Management and Budget in the Program Planning and Budget Formulation Division. She serves a liaison to NMFS’ Office of Science and Technology, the Ecosystem Observations Program, and the Climate and Ecosystems Productivity Program. She also tracks all of NMFS’ research and development activities at their six Science Centers. Each year, the President of the United States submits a budget request asking Congress for money to support NOAA activities. It’s kind of like asking for an allowance and then telling your parents the reason why you need the money. In Jeannine’s line of work, telling the reasons why money is needed is called a budget justification. Each fiscal year (Oct 1 through Sept 30) she works on budget justifications for NOAA’s fisheries research programs. This involves talking to a scientist to understand his/her plans for research in the upcoming year and writing a summary about the need for the activity, the cost of the activity, and the benefits to the country. She says that although her job description changes day to day, she spends much of her time responding to questions from the Department of Commerce, the Office of Management and Budget and from Congressional staff.
I found it interesting that Jeannine first became interested in working in marine biology while watching Jacques Cousteau’s TV show as child. Later, she volunteered to work with National Museum of Natural History curator Dr. Clyde Roper after watching a Discovery Channel program on giant squid. She’s proud to say that one of her reference letters for graduate school had a giant squid at the top of the letterhead! Ten years later, Jeannine’s back where she started as a research collaborator in the Museum’s Division of Fishes.
Sunset from Cape Cod Bay
She says the best part of her job is when her efforts are successful in getting funding for NMFS’ programs. “It’s nice to know that you’re a part of a larger effort to understand the oceans and marine life,” says Jeannine. To prepare for a NMFS career in program planning and budget formulation, Jeannine recommends a biological degree, such as one in fisheries science, marine biology, environmental biology, or environmental policy. You should be comfortable working with numbers and asking a lot of tough questions. Jeannine spends a lot of time writing, creating slideshow presentations, designing websites and talking to different groups, therefore good communication skills will help as well. Internships, fellowships and volunteering on NMFS cruises are also great ways to know how NMFS works.
Personal Log
What a beautiful day! It was a wonderful experience to be steaming on board the ship. It was a warm, sunny day, although it was considerably cooler when we got away from land. Today was the first day that I was able to get weather and sea measurements from the bridge. I am hoping to become independent in reading the instruments that take these measurements by the time we return.
On the return trip, I was able to sit up on the flying deck (which is the top level deck) and watch as we pulled back in to the harbor at Woods Hole. The view was incredible and made me feel so far away from Virginia! Don’t worry, I am still planning on returning to school on the 18th! I am sure once we begin with the more intense work load that comes with trawling and completing biological sampling, paired with the overnight (6 PM to 6 AM) watch that I have been assigned to, I will be looking forward to returning to my own bed soon enough!
Question of the Day
A seafaring riddle for you: What is alive without breath, As cold as death, Never thirsty, never drinking, All in mail but never clinking?
