Science and Technology Log

Taking part in the 2009 Sea Scallop Survey has been an experience of a lifetime. I learned how to identify many different species of fish, to use the FSCS computer system, and the many sampling techniques that are involved in fisheries research. I met some incredible people that inspire me to continue volunteering whenever I can for the sake of scientific research. I am very familiar now with many jobs and careers that one can have working for NOAA. My students will be very excited to see all the photographs and data that were collected on this survey. I have planed numerous activities where my students will use the data collected in the sea scallop survey which will help prepare them for the New York Schools Regents Examination. Some research scientists that I have met have promised to come and speak to my classes and educate my students on the many careers that NOAA offers. My roommate Lollie Garay and I had such a remarkable time on the Hugh R. Sharp. Although we worked different shifts, we had a few hours each day to discuss some lesson plan ideas and share pictures with each other.

I really enjoyed working with the night watch. My Watch Chief Geoff Shook really knows how to manage a team. He is full of information, patient, and extremely helpful. Cristina, Geoff, Steve, Glynn, A.J., and I really worked well together. The Chief Scientist Vic Nordahl is an amazing guy. He can multitask like no other person I have ever seen. He works on several different tasks at once while checking the data, and even making a little time for Lollie and me too! Kevin McIntosh is another incredible scientist. He and Vic are very busy running the Sea Scallop Survey but he also has made himself very available to Lollie and me whenever we have any questions. Kevin is always there to help with data and explain how different instruments work as well.

I really feel privileged to have had the opportunity to work with such a great group of people. I will never forget it! I have taken so much away from this trip, and my students will appreciate all the new knowledge I will continue to share with them. I am very excited to be returning home tomorrow morning. We are expecting a 10-hour steam tonight and hopefully we will arrive in Lewes, Delaware around 6:00 AM. The last thing we have to do tonight is clean our stateroom and the labs. This is easy work compared with all the tows we are accustom to sorting and measuring.

Science and Technology Log

Today was a great day. It was a little cooler than usual but many tasks were accomplished. I am now able to identify almost every species of fish that comes up in the dredge. I know how to run events and my night watch team works together in harmony. Everything ran so smoothly today, and I believe it is all due to the fact that we get along so well. I have become good friends with everyone on my watch and some day crew as well. Relationships are important when you’re living with all different people in close quarters.

I had a chance to talk with Steve Ellis today. He is a port agent for NOAA Fisheries North East Regional Office. He works with management plans and is a Fisheries Reporting Specialist. Port agents like Steve are stationed where major commercial activity is located. He works under the fisheries statistics office and monitors commercial fisheries landing in order to supply data for proper fisheries management. Steve tracks fishery events and maintains reporting requirements that operate in U.S. waters. This helps the government get quota for different species of fish along with their age and growth. This also becomes a part of our Gross National Product. Steve also helps interpret regulations and provides a link between fishermen and managers.

I also got a chance to sit and talk with Glynn Rountree. He is a volunteer on this NOAA Sea Scallop Survey and he has been volunteering on many cruises since graduate school. So far he has been a volunteer on at least 50 cruises for the Environmental Protection Agency and NOAA. Glynn has a Master’s Degree in Oceanography and is very helpful in answering almost any question you have about various animals and fish. Glynn worked in research administration for 8 years, and now has a job with environmental regulation of home building. It is important to understand that you do not have to be a scientist to work in a science field. There are so many significant issues that will affect us directly that it is very important we stay educated on issues like global warming, climate change, and endangered species. We need more college students studying these issues not business administration.

Animals Seen Today

Here you can see the many different sizes of sea scallops.

Science and Technology Log

So Far the sea scallop survey has collected 76,170 sea scallops which can also be expressed as 9,251 kilograms. This is a tremendous amount of scallops and the survey is not even a third of the way complete. At stations where crabs and starfish were sampled we have collected 8,678 cancer crabs and 279,768 starfish (Asterias) so far. Without a reliable database like FSCS it would be impossible to keep up with such a large amount of information.

Today I got a chance to talk with Shad Mahlum. He is a seagoing technician for NOAA and was born and raised in Montana. He has experience working with freshwater surveys. In the past years he has studied how beaver dams influence native and non-native species of freshwater fish. Shad also spent some time looking at various cattle grazing strategies and how they affect food chains. Shad loves working on the open ocean and the physical process of sea scallop surveys. Shad hopes to work with freshwater and saltwater projects in the future.

Here I am holding a scallop and a Red Hake.

As I was gazing out into the deep blue sea a very large animal caught my eye. I was so excited to see another Finback Whale. They are the second largest animal on earth after the Blue Whale. They are known to grow to more than 85 feet. Finbacks are indifferent to boats. They neither approach them nor avoid them. Finback Whales dive to depths of at least 755 feet. They can grow anywhere from 30-80 tons. Finbacks eat Krill, fish and squid and their population numbers are approximately 100,000 or more. The only threats Finbacks have are polluted waters. It is incredible to see such a large animal breaching out of the water. I will never forget it.

Animals Seen Today

Wrymouth Squid, Eelgrass Slug, Razor Clam, Lobsters, Green Sea Urchin, Macoma clam, Sea Stars (Asterias), Horseshoe Crab, Fourbeard Rockling, Palmate Sponge, Hermit Crab, Black Clam, Golden Star, Tunicate, Winter Flounder, Surf Clam, Yellowtail Flounder, and Sea Mouse.

Sorting through more sand dollars on a chilly, overcast day.

Science and Technology Log

Today we had some extremely large tows of sand dollars. Thirty-two baskets filled to the brim with sand dollars in one particular tow. It’s hard work when you have to sift through hundreds of thousands of sand dollars looking for little Cancer Crabs. Too bad they were not real dollars. Today I got the opportunity to sit with my Chief Scientist, Victor Nordahl. Although he is very busy he sits and talks with Lollie Garay and me daily about how we will implement all the information we are gathering into the classroom. Today was different; I got a chance to ask Vic about his demanding daily tasks, and his career. Vic is a Fishery Biologist. He has been working for NOAA’s NEFSC (Northeast Fisheries Science Center) for 17 years. His main job is to standardize the shellfish surveys and maintain the gear. When he is not working on equipment like the dredge for example, he is performing a quality check on all the data that is collected.

In 2007, the NOAA Ship Albatross IV was retired, which was the vessel the sea scallop survey was always conducted on. This vessel had the old dredge which is similar to the new dredge. The new dredge has some modifications such as rollers on the goose neck to prevent digging into soft substrate. Another addition to the new dredge is the twine top which allows fish to escape easier that the old dredge. The equipment was very hard to come by for the old dredge, so this made repairs exceptionally difficult. With the new dredge there are some very fresh and innovative ideas. Vic plans to introduce a Habitat Camera which can take many overlaid digital pictures of scallops which will have a continuous stream of real-time data.

There are many advantages to this new method. The most important being the habitat camera would mean far less tows which is less intrusive and damaging to the habitat. With this habitat camera it would be possible to see an absolute abundance of sea scallops due to the fact you would be able to see approximately 90% of the sea floor, and have digital images on file as well. You would have to dredge much less to see three times more. This new technology is very promising and some steps will be given a test run on Leg 3 of the sea scallop survey a few months from now. I can’t wait to read all about how this new technology will improve the quality of sea scallop surveys.

When you think about 2 weeks you do not think of it as being an extremely long amount of time. Well, when you’re on a ship for 2 weeks it can feel like a lot longer. I must say I miss my husband Alex very much. Regardless, I am so lucky to have the opportunity to work with scientists like Vic Nordahl and Kevin McIntosh.

During the summer I participate in a two year fellowship with Columbia University called The Summer Research Program for Science Teachers. This is a great program where NYC science teachers are working with state-of-the-art technology along side research scientists. We participate in and bring back to our classrooms the newest information on some groundbreaking research going on at the moment. This program has endless advantages. The networks created are for a lifetime, and teachers in the program get the chance to collaborate ideas and share lessons and tips with each other. There are speakers, seminars, and fieldtrips that inspire science teachers to go the extra mile to interest students in research science. Jay Dubner and Sam Silverstein run this incredible summer research program and I can’t wait to tell them all about the research I am taking part in and how the program inspired me to become a Teacher at Sea. During the summer 2009 I will continue working with Dr. Robert Newton at Lamont Doherty Earth Observatory studying and sampling water at Piermont Marsh.

What a morning we had today. It was sand dollar heaven aboard the Hugh R. Sharp. At least 3 of our tows were filled with hundreds of thousands of sand dollars. My work on this Sea Scallop Survey is pretty regular now that I have the hang of it. The dredge goes down and scallops, cancer crabs, starfish, hermit crabs, sea sponges, sand dollars, and sea slugs come up. We manually sort through the catch and weigh and measure the fish, and sea scallops. Every third station we count all the cancer crabs and starfish. Depending on the strata, various stations require five sea scallops to be measured for age and growth and their shells are preserved for later lab work. This work is very important for maintaining a long term study. With FSCS all the data can be organized and used to draw conclusions about the overall health of areas along the Mid-Atlantic.

Today I got a chance to talk with Kevin McIntosh. He is on the day watch so I do not get a chance to work closely with him, but he is a great scientist. He is a Biological Science Technician and also plays several roles along different cruises. He is often a Chief Scientist, FSCS Administrator, and he specializes in combing over data, and auditing data. Sometimes he serves as Watch Chief. At the moment he is working on a Scallop Imaging Machine where scallops can be photographed which would reduce the manual work load of the scientists with even better data collection resources. There would be a record of every scallop collected which means sub-sampling would be obsolete. Kevin is also working on a team which is collaborating to create FSCS 2.0 capabilities. Some highlights of FSCS 2.0 include a GPS location where data can be automatically retrieved and stations can be programmed to display directions and sampling requests.

This would also cut the sampling time in half. You would be able to have all the stations’ information at your fingertips. These new improvements would also make data cleaner and easier to audit and help double check your work. Kevin works very hard. Every time I see him he is working on something new.

Personal Log

I really enjoy sitting and talking with the crew here on the Hugh R. Sharp. Everyone has so many great projects going on and new goals for fisheries research. I found out today many of the crew have served time in the military. I now have even more respect for them. Fisheries research is hard work and there is so much that goes into this research that is often ignored. Especially the long hours of manual labor and the time needed to plan out each stations sampling routine. Today the seas were rough again. When the boat is rolling all over the place it is very hard to walk from one place to another. I learned a new trick today. Always keep your knees bent in rough seas; it makes walking a lot easier. Looking at the horizon also helps one from becoming sick, at least for a little while.

Sampling the water column is a vital part of oceanographic work. Aboard the Hugh R. Sharp casts are conducted every third station using a special instrument called a CTD. CTD stands for conductivity, temperature and depth. Water samples are brought back aboard collected by a Niskin bottle two times a day. These samples are used to calibrate the CTD. Scientific research should always be double and even triple checked to calibrate all the various instruments being used and guarantee they are functioning properly.

Today I got a chance to sit and talk with my Watch Chief, Geoff Shook. He is extremely organized and very helpful. He ensures the data is correctly entered into the FSCS computer database and watches over the night crew. Geoff was always interested in oceanography but during his undergrad he had an opportunity to study fisheries instead. Geoff is mainly interested in fish populations. He spends about 140 days out at sea every year. About a week before this Sea Scallop cruise Geoff just returned from a 2 leg bottom trawl fish population survey. Directly before that he was on a Monkfish Survey that concentrated on locations Monkfish are found along with the population index. Geoff spends his time on cruises auditing data, servicing all the gear and fixing the scallop dredges. He is the head of inspections and we can thank him for that. Geoff organizes all the data so the ships have all the latest information. Geoff is very hardworking and patient. It takes a lot of hard work to do his job. I commend him for his dedication to fisheries research.

I also got a chance to sit and talk with Cristina Bascunan. Cristina is a physical science technician. I really enjoy talking with her and look forward to working with her and Geoff every night. Cristina was a biology major in college and started volunteering on sea scallop cruises her sophomore year. She got a job with NOAA and started working on oceanography cruises that follow Plankton. There were 40 set stations on Georges Bank where Plankton were collected and sampled. Cristina also worked on SOOP cruises. SOOP stands for Ships of Opportunity Project. Once

a month this cruise would take a scientist along and travel to Bermuda and complete a CPR. A CPR is a Continuous Plankton Recorder. The Plankton is sampled by a silk cloth tow that is dragged behind the boat. The silk cloth is treated with a preservative so further tests can be conducted later on. This helps create a time series where surface temperature could also be measured and mapped out. This data collected aided in many other studies and is extremely important. Cristina works very hard and she definitely has my respect.

Today was pretty exhausting. All these 12-hour work shifts with no days off are finally catching up to me. I have a newfound respect for the crew of technicians and scientists that work these hours year round. Today the seas were really rough. We had at least 6-foot waves and water crashing onto the deck. When the moon makes a circle in the sky you’re moving. It’s very hard to work when the ground is moving below your feet. I spent a bit of time today hanging over the ship’s railing. Can you guess what I was doing? I sure was seasick for a little while this morning, but it passes quickly which is good. Every night before I go to sleep I listen to the ship’s noises. I hear some bangs and clicks, but my favorite sound is the waves crashing into the side of the boat. I literally rock and roll until I fall asleep. It’s about that time right now. I can’t wait to climb up to my bunk and get some rest.

Sea Scallops’ number one predator is starfish. Starfish are very strong. They pry open the shell and then push their stomach inside and devour it. Starfish are very abundant in the Mid-Atlantic. Many tows yield hundreds of starfish. It would be too time consuming to count every one of them so sub-sampling is done to attain an estimate of starfish. The entire catch is sorted but only a portion of the catch is measured. This is a good method when there are many starfish and little substrate (trash). The substrate is then collected in buckets and volume can be determined. The data is then entered into the FSCS computer system. As I mentioned before FSCS is extremely advanced and is a one-ofa-kind biological data system. Prior to 2001, Fisheries Surveys information was sent to federal prisons to be entered into a computer data base. This took an extremely long time to process. Inmates would get compensated as little as a penny per log sheet. This was dangerous and the data could have been destroyed or lost. Today all data is backed up on a server in three different locations to secure data entries. This long-term study about age and growth of sea scallops helps scientists see a trend in different area’s ecosystems.

I have met some intriguing scientists aboard the Hugh R. Sharp. Shayla Williams is a research chemist for NOAA. She specializes in fatty acid analysis of Fluke. A fatty acid analysis is like a fingerprint of what you eat. By studying fatty acid in certain types of fish she can make generalizations about the health of an area. Shayla has done research on NOAA cruises since 2006. She has sailed on the Hudson Canyon Cruise, the Fall Fish Survey, and the Spring Fish Survey to name a few. It takes a whole crew to run a ship and the Hugh Sharp has a very sharp crew. Wynn Tucker is an Oceanographic Technician aboard the Hugh R. Sharp. She has worked for NOAA, EPA, and the Navy. She loves being out on the open water and I don’t blame her. It is magnificent to look out and be surrounded by blue as far as the eye can see. A.J. Ward is another crewmember aboard the Sharp. He works the inclinometer which lets the scientists know of the dredge is in the right spot on the bottom of the ocean floor.

Today was a great day! It was beautiful weather and I got a chance to talk with some of the crew members on the Sharp. I saw a whole school of dolphins less than three feet from the boat. It was incredible! I ran up to the bridge to get a better look and saw a couple of Finback whales as well. It is extremely hard to get pictures because they surface for a few seconds and then dive back under water. There are many fish in this area known as the Elephant Trunk. I can’t wait for tomorrow! Another exciting day where I have the opportunity to be working with cutting-edge technology and incredible scientists. For now I can’t wait to get some sleep.

Science and Technology Log

Sea Scallops are found in western North Atlantic continental shelf waters from Newfoundland to North Carolina in waters cooler than 20 Degrees Celsius. Commercial fishing is conducted in waters off the Gulf of Maine, on Georges Bank, and in the Mid-Atlantic offshore region. Scallops grow rapidly during the first several years of life. Scallops increase 50-80% and quadruple their meat weight between the ages 3 to 5. Sea Scallops become sexually mature at age 2, but scallops younger than 4 contribute little to the overall egg population studies explain. Spawning occurs in late summer and early autumn. Eggs become buoyant after fertilization, and larvae remain in the water column for 4 to 8 weeks before settling to the bottom of the sea floor.

Communication between all the people on board is key to successful sea scallop tows. Operational procedures must be put in place to ensure all parties know exactly what is expected of them and when. The bridge has a list of all station numbers which is provided by the Chief Scientist. The bridge announces over radio “10 minutes to station” and the science team lets the bridge know if more time is needed to prepare for the tow. Every third tow and twice per day a water sample is taken. These samples are collected before the dredge enters the water. One technician ensures the inclinometer has been offloaded in time before the dredge is emptied and sorted. The bridge makes sure the tow passes through the middle of the station and retains 75% of the catch. If there is a problem the bridge notifies the science team. The science team then checks the Knudsen Depth Display to determine the designated wire out or scope that is needed for the station. The bridge will then come up to speed of about 4 knots. At this time the bridge will announce to begin deployment of the dredge and the winch operator (dredge operator) will set the dredge over the stern. The winch operator will stream enough cable to reach the “0” mark in the wire and then set the winch metering to zero.

The dredge is then deployed as quickly as the winches can spool which is approximately 60-65 m/sec. When the winch man has achieved the desired scope and locked the brakes, they should observe the trawl tension. Start tow begins once this occurs. The scientist will then start the countdown for the 15 minute tow. The bridge sets the speed over bottom at 3.8 knots. The scientist in the lab running the event will give several warnings; 1 minute warning, 10 second warning, and then finally haul back. The winch operator will start hauling back at maximum allowable speed to pull the dredge off the bottom. Once the dredge is on deck, inclinometer should be offloaded, the catch is dumped, and the dredge is secured. The vessel then heads to the next station on the Chief Scientist’s list. These standard operational procedures discourage any errors that might occur if procedures were not in place.

After the catch is on the table it is sorted and sampled by using a FSCS computer database. The Fisheries Scientific Computer System is a collection of integrated electronic devices used to gather and store station and biological data. FSCS uses tough screen monitors and motion compensation scales with electronic measuring boards. This helps reduce human error and is a very sophisticated instrument.

Personal Log

We started out the night shift with two medium sized clean tows. There was very little sand and clay which helps the sorting process go very quickly. I personally counted 236 cancer crabs and over 300 sea scallops. The nature of sorting is becoming very familiar to me, and I enjoy learning new things everyday. I spoke with the Chief Scientist Vic Nordahl for a while and discussed various ways of incorporating all the data being collected into the classroom. Vic is extremely busy but makes time to discuss and plan out activities for the Teachers at Sea to bring back to the classroom. Lollie Garay is the other Teacher at Sea aboard the Sharp. She is a middle school teacher from Houston, Texas. We both enjoy learning how research is collected out at sea. There are 22 people total aboard the Research Vessel Hugh R. Sharp and everyone communicates and is friendly with one another. I really learned a lot about protocol today and now I completely understand how everything runs so smoothly. I can’t wait to get some sleep. Fisheries work is not easy!

There were 5 tows today on my shift. I discovered open areas have far fewer sea scallops in each tow compared to closed areas. In the open areas each catch was mostly starfish and cancer crabs. In the closed areas there were many sea scallops and various fish collected. Five scallops from each basket collected were processed for weight, length, gonad weight, and meat weight. The sex of each sea scallop is also identified and all data is entered into the FSCS computer system. The sea scallop shells were labeled and stored away for further identification. If the sea scallops rings are clear and visible, lab tests can be done to identify its exact age and health. The Nordic Pride which is a commercial vessel contacted us today. The Nordic is working its way through the areas the Hugh R. Sharp already sampled. The Sharp will compare tows with the Nordic. The Nordic surveyed with NOAA research vessels before and is taking this opportunity to survey with NOAA again. In the next few days we expect to see the Nordic Pride a few miles away.

Today I feel much more confident about the tasks at hand. I have a lot of support from the crew and the Watch Chief. I am always up for new assignments and am very confident I can complete them correctly. Around 5:30 AM I saw about 12 white-sided dolphins. It was incredible. They are curious and fast animals. They swarmed around the Hugh Sharp for a while until they got bored with us and continued on their way. Not long after the dolphins appearance 2 Finback whales surfaced. What an incredible night. I hope to see more dolphins and whales and hopefully get a picture of them.

Today around 08:00 we set sail to begin the Sea Scallop Survey that will be conducted on this cruise. This annual series of quantitative data is collected to determine the distribution and abundance of Sea Scallops. This survey will randomly collect sea scallops from Virginia all the way to Canadian waters. The Chief Scientist and his field operations officers randomly selected stations with in depth boundaries called strata. These selections are either in closed areas where commercial fishing is prohibited, or open areas where commercial fishing is allowed. Areas may be closed to protect the population growth for 2-3 years. The government will most likely allow closed areas limited access with recommendations from NOAA. Samples of sea scallops are taken randomly by using a dredge.

The dredge is 8 feet wide and 20 feet long. It has a metal frame with a ring bag off the back. Each ring is 2 inches in diameter and the bag is lined with a 1.5 inch twine mesh liner. The bag is closed on the top and open on the bottom. This survey consists of three Legs. Leg I will complete approximately 200 tows. Each tow is deployed to the bottom of the sea floor. An inclinometer is used to ensure the dredge is completely at the bottom of the sea floor. This instrument measures time on the bottom. If you know your average speed and multiply it with time this equals the distance towed on the bottom. Timestamps are matched up between the data collected at FSCS and the inclinometer. Each tow lasts for 15 minutes at a speed of 3.8 knots. Tows can be as shallow as 20 meters, and as deep as 150 meters. After a tow is pulled up from the sea floor, 4 to 6 people manually sort through the catch and pull out Sea Scallops, Starfish, Cancer Crabs, and all fish. All samples that are collected are placed into baskets. The baskets are weighed and sea scallops and fish are measured.

Sorting scallops brought up by the dredge

Today I spent most of the day feeling sea sick. I thought it would never end. Now I feel like a million bucks. It took me a little while to get my sea legs. Today I learned so much. I spent most of the day asking a lot of questions and watching everyone closely. I work the night shift from 12:00 AM to 12:00 PM. There is much excitement when a tow comes in and is emptied on the sorting table. The crew gets excited to see what we brought up. Today we deployed 9 tows on my shift. We had quite a few clean tows and many muddy tows. A clean tow has many scallops and very few mud clumps. Life at sea is not easy, it is hard work. The living conditions are great on the Sharp. The galley is stocked with anything you can imagine. Meals are excellent and snacks are a part of sea life. My stateroom is very comfortable and the showers are very nice too.

I really enjoy sea life. The scenery is incredible. At night you can see the moon so clearly and the light gently reflects off the rolling waves. During the day there is blue sea for miles. It is very relaxing. Everyone is so nice and willing to explain how things are done. I feel great and I am looking forward to resting for a while.
