On my last blog I introduced you to five species of shark found so far. I think you can tell which one is my favorite, which is yours?
Even though our mission is to collect data on sharks, you never know what might come up on the end of a hook (or tangled in the line!). Data is still collected on just about everything else we catch. For today’s blog I have put together a photo journey on the so many other beautiful creatures we have caught.

Science and Technology Log
Our first full day at sea (and at work)! We left the dock at Woods Hole, MA yesterday at 2 pm and headed out past Martha’s Vineyard and Nantucket. While steaming towards our sampling site, we practiced two very important safety drills — a fire drill and the abandon ship drill. The abandon ship drill was unique in that we had to don our survival suits (supposedly in a minute but I think I took longer than that) that protect us in the water from hypothermia and also help keep us afloat.

Around 6 pm we reached our first sample location and the “day team” (that’s me and some fellow volunteers) started our work. The testing protocol is fairly simple: sample sites have been predetermined by computer. Survey sites are selected based on depth and location (latitude and longitude). When we reach those locations, a large sled-like cage called a dredge is lowered into the water and dragged along the ocean floor for a prescribed amount of time (generally 5 minutes).
This cage goes on the ocean floor scooping up samples for our analysis.
The dredge is then brought up and the contents emptied onto the deck. Our work then takes 10-15 minutes to sort through what is brought up, keeping those items we are surveying or counting, and throwing the rest back into the water. We attempt to identify organisms we bring up and we count all live bivalves, any gastropods, hermit crabs, starfish and all fish. Species we identify and measure are the surfclam, the ocean quahog, the southern quahog, and sea scallops. Once we’ve separated out what we need, we weigh the catch then measure the size of each item collected. We throw everything back into the water and clean up the deck while heading to our next location. The procedure is repeated about twice each hour. For our work on the deck we wear protective clothing, hard hats, and of course, a life vest.
Personal Log
There are seven volunteers aboard this trip, including myself. They are a varied group from all over but are all very interested in ocean science. Some of them are college graduates, some are still in college and we are all first-timers on this type of research vessel. We were assigned a 12-hour shift, either noon to midnight or midnight to noon. I feel fortunate to be on the noon-midnight shift as that means I don’t have to alter my sleeping pattern much. It’s tiring work but the good part is there are breaks between each haul so most of us have our books with us on the deck (so handy to have a Kindle!). The crew here is as varied as the volunteers, from all over the country and they are all very good at what they do. I initially thought having 4 girls sleeping in a room the size of a walk-in closet would be difficult but it’s not. At any given time two of us are on deck, on duty, so the room is available for sleeping, changing, showering, etc. We all respect quiet below deck because at any given time, someone is always trying to sleep!
Interesting Things Seen Yesterday
A shark with a rather large fin above the water was following us from a distance for a while — maybe curiosity? We brought up several skates (they look like rays) the largest being about 12 inches long. They are incredibly beautiful up close, looking almost angelic. It seems a shame they have such a bad reputation!

In one of my conversations with Captain Jimmy, he told me that he likes scientists to “enter the ship as customers and leave as family.” Without a doubt, I feel like the whole R/V Hugh R. Sharp team has made that happen. From the excellent meals cooked three times daily, to the willingness of the crew to answer any of my questions, I have felt included and welcome.
Sunset from the deck
My fellow scientists have made travel on this journey fun and worthwhile. I can’t count the number of times someone yelled over to me, “Hey Kathleen, get a picture of this. Your students will love it!” It has been a pleasure to be around others who are curious and passionate about the sea.
In my classroom, I try to convey to my students that science is about collaboration. I will have many real life examples to share with them when I return.
My thanks to the NOAA Teacher at Sea Program, my colleagues and students at Freeport Middle School, and my family, for supporting me on this adventure of a lifetime!

Science and Technology Log
It has been amazing to me to see the variations in the catches from the many tows. When the tension on the wire used to haul the net is high, it might be because we have a huge haul of sea scallops. Sometimes the table will be filled with so many sand dollars it is difficult to see anything else. We had a number of tows that contained large amounts of brittle stars. The arms of the brittle stars move like little worms. (It is eerie to see thousands of them wiggling.) The last tow, in the open area, had only forty-six scallops. The pile was filled with quahogs, urchins, starfish, sea cucumbers, hermit crabs, and rocks. Sometimes the animals we collect are covered in mud and sometimes the sediment is very sandy. We are now traveling in the shipping channel and the sea floor is rocky. Before we began to tow in this area, the scientists put the rock chains on the dredge. There is also a metal chute attached to the table so that the larger rocks can more easily be rolled back into the ocean.
Brittle Stars
We have now completed the inventories in the closed areas of Georges Bank. I learn that large areas in the Gulf of Maine had originally been closed as a measure to restore groundfish stocks. What scientists discovered is that, over time, the sea scallops flourished in the closed areas. It was an unintended result of the fisheries management policies.
There is always something interesting to learn about the species that we collect. Sea scallops have the ability to move through the water column by clapping their shells together. Sometimes, moving up five or six inches can mean escape from a predator like a starfish. (Of note, during this study we also count and measure empty sea scallop shells, provided that they are still hinged together. These empty shells are called clappers.) Speaking of starfish, on this trip we have seen five species of starfish, in colors ranging from purple to yellow to orange. The common name for my favorite starfish is sunburst, an animal that looks just like it sounds. Monkfish, sometimes referred to as goosefish, are called an angler fish. There is a modified spine at the top of its mouth that appears as though the fish is dangling bait. With this structure, the monkfish can lure a prey near its enormous mouth (and sharp teeth) and capture it. The longhorn sculpin feel like they hiss or grunt when they are picked up. I have learned that it is likely the sound is the vibration of a muscle in their chest.
Scientist of the day watch
The technology used to support the science on this survey is remarkable. In the dry lab, there are fifteen computer screens being used to track all of the data collected. These are in addition to the many that are being used to manage the ship. Everything is computerized: the CTD collection, the route mapping, and the information about the species we are catching. After each tow, the Chief Scientist or Crew Chief can immediately plot the data from the catch. Several screens show images from the cameras that are placed at various locations on board the deck. From the dry lab, the scientists can watch the dredge go in and out and view the tension on each cable. When the technology fails, as it did for four hours one day this week, it is up to the crew and scientists to figure out what is wrong and how to fix it.
When the ship is off shore for hundreds of miles, the skills and talents of each individual on board must be accessed for anything that happens out of the ordinary. The Captain is the chief medical officer. The crew acts as firefighters. The scientists and crew work together on mechanical issues – like yesterday when the hydraulics on the CTD stopped working. Working aboard a scientific research vessel is perfect for those who are flexible and innovative.
Personal Log
It is difficult to explain how beautiful the scene from the back deck of the ship looks. All I can see to the horizon lines is dark blue water. Flocks of seagulls follow the ship to scavenge the buckets of fish we throw overboard. Last evening the full moon was bright and round. When I breathe in the salt air, I think about how grateful I am that I am here.

Question of the Day (See the answer at the end of the post)
How do you count a basket of crabs?
It’s hard to believe that we’re already at the halfway mark of the cruise. Since my last log, we’ve covered a total of 966 nautical miles. Today, we’ve traveled from Hudson Canyon which is 60 nautical miles east of Atlantic City to about 50 nautical miles from the coast of Point Pleasant, NJ.
Bucket of Crabs
Each day, the boat stops at predetermined points along the route. At each stop, the scallop dredge is lowered to the ocean floor at depths ranging from 15 to 60 fathoms. The dredge is then towed for 15 minutes at a speed of 3.8 knots. When 15 minutes has passed, the dredge is brought up and the catch is dumped onto a platform were we all wait anxiously to see what comes up. Once the empty dredge is secure, we get to work sorting the catch. Scallops and fish get separated, with everything else collected into baskets, cataloged as “trash” and returned to the ocean. The scallops are measured, and the fish are sorted by species, then counted, weighed and in some cases saved for further scientific study back at NOAA labs. Once everything has been counted, weighed and measured, it’s time for my favorite activity – shucking! Scallops are shucked and if there’s time, washed bagged and placed in the deep freezer for Paul to use in the galley for meals. To date, we’ve completed 90 tows and dredged 23,212 scallops.
What comes up at each catch depends on the location of the tow. The southernmost, areas that have been open, or those areas that have recently been closed will usually yield fewer scallops. Scallop yields increase as we head northward and in areas that are closed to fishing. In addition to scallops, our tows have included a variety of deep sea fish, starfish, lots of live sand dollars (with their accompanying green slime), and very often, mud.
At select tows, representative samples of scallops are processed beyond the usual length measurements. The shells are scrubbed clean and weights are recorded for the meat and gonad (reproductive organ). The shells are then labeled and bagged for transport to the lab where they will be aged. The age of scallops are determined by counting the number of growth rings on the shell – similar to counting rings on a tree.
Every three tows is my favorite – Crabs and Stars!! In this tow, in addition to the usual sorting and measuring, all Cancer crabs are collected, counted and weighed and a representative sample of starfish are sorted by species, then counted and weighed. Astropecten, a small starfish is a predator of scallops and the most abundant species of starfish that we’ve counted. Usually, a tow that has large numbers of Astropecten has very few scallops. Being a stickler for detail, having the job of counting starfish has been perfect for me.
Did you know?
Starfish eat a scallop by attaching themselves to the scallop in numbers, forcing the shell open, then extruding their stomachs into the shell and digesting the meat.

Personal Log Day 3 – Thursday, May 12, 2011
With my sea sickness over after the first day and having adjusted to my new sleep schedule — I actually get to sleep a full 8 hours! — the days are starting to take on a nice flow. It’s been great being part of a team. We’re like a well-oiled machine. Everyone in my crew continues to be generous, sharing the best shucking techniques and giving me a little extra time to take photos and collect samples. We’ve jokingly renamed the “crabs and stars” tow to “crabs, stars and mud”. It’s really hard to count starfish when they’re covered in mud. Dinner was especially delicious today with salmon in pesto sauce with potatoes and broccoli.
Day 4 – Friday, May 13, 2011
The day started out cloudy and overcast, but the sun made an appearance late in the afternoon. The first tow of the day was my favorite — Crabs and Stars!! — with accompanying mud. As part of the Teacher at Sea program, in addition to my logs, I am required to write a lesson plan. I’ve started to draft what I think will be a great unit using the sea scallop as a springboard to explore issues in ecology and the nature of ecological science. Highlights will be an Iron Chef style cooking competition using scallops and a design challenge where students will have to build a working model of a scallop dredge. Vic has been great with providing whatever data, materials and background information that I need for my lessons. Lunch today was chicken burritos with fresh, spicy guacamole.
Day 6 – Sunday, May 15, 2011
Since its Sunday, I decided to take it easy and instead of trying to get a lot done before my shift and during the breaks, I took it easy and watched a little TV. With satellite TV and a large selection of DVDs, there are always lots of options. Although the guys tend to prefer sports or reality TV. The first few tows were back to back which meant little time for breaks, or snacks, or naps. Just enough time to clean up, shuck and be ready for the next tow.
Day 7 – Monday, May 16, 2011
The trip is half over. It’s hard to believe. The tows were once again, back to back with a fair amount of scallops, but I think after today, we won’t need to shuck anymore. Yay! Today was the day that the animals fought back. I was chomped by a scallop and a crab! The scallop was more of a surprise than a pain, but the crab clawed right through my glove. After days with no restrictions, we received the warning from the engineers today that we have to be careful with the faucets. Dripping faucets waste water and it takes time for the water to be converted through condensation in the condenser to usable water. If we’re not more careful, we’ll be faced with restrictions on how much water we can use……… I hope that doesn’t happen since I think we all officially smell like fish. Lunch today was cream of asparagus soup, yummy and reminiscent of my recent trip to Peru. The only thing missing was Quiona. And finally, today was the day that I’ve been waiting for. I found my favorite ice cream. I’ve been rationing myself to one per day, but after I found my favorite – butter pecan ice cream sandwiches – I could not resist a second.
NOAA Teacher at Sea Richard Chewning Onboard NOAA Ship Oscar Dyson June 4 – 24, 2010

Science and Technology Log
Throughout this cruise I have been continually impressed with the engineering of the NOAA ship Oscar Dyson both in terms of modernization and capacity. State of the art technology can be found throughout the ship from the bridge to the engine room. Computer touch screens are used to control such operations as navigation on the bridge, power management in the engine room, and data entry in the wet lab. Junior engineer Walter Daniel summed up the advanced look and feel of the ship well; in comparison to the many vessels he has encountered in his career, he likened the Dyson to the Starship Enterprise of the science fiction franchise Star Trek. Even though the Dyson is one of the most technologically advanced fisheries vessels in the world, the engineers still get their fingers dirty from time to time. Although most of the equipment in the engine room can be adjusted with the simple touch of a button, flip of a switch, or turn of a knob, the Dyson’s veteran engineers still carry a screwdriver and wrench in their back pocket. Fred Ogden, first assistant engineer, told me he always likes to be prepared to bypass the computers and be able to make an adjustment by hand if needed, and you need to have the right tools for the job at hand. Recognizing that sometimes a person needs to get back to basics and that one should always be prepared, Fred says he never goes fishing without packing his sextant. Tracing its origins to the days of Sir Isaac Newton, the sextant is a tool used for navigation that only needs a clear view of the sky and horizon to work!
Diesel fuel centrifuges
At full power, the Dyson can reach 15.0 knots or a little more than 17 miles per hour. A knot is a unit measurement of speed roughly equal to 1.151 miles per hour. Four diesel generators capable of 3,017 horse power turn the Dyson’s shaft and prop. Horse power is a unit of measurement of power. To give you some perspective, modern cars typically only have 125 to 200 horsepower. To ensure these generators operate as efficiently and cleanly as possible, diesel is first cleaned using powerful centrifuges (machines that rotate very quickly to separate oil from the fuel). Fuel is also filtered twice more in each engine using filters. By burning clean fuel, the Dyson reduces pollution output and increases the life of the generators. Most of the oil and dirty water can be filtered on board to remove the impurities and reused.
Two of the Dyson’s powerful diesel generators
The Dyson also has two desalinization machines. What is desalinization and why is it important? ‘Desalinization’ is easy to subdivide and define to reveal its meaning. ‘De-’ is a prefix that means removal or reversal. ‘Salin’ is a French root word that means salt. ‘-zation’ is a noun suffix meaning an action, process, or result of making. If you put the parts together, desalinization means the process of removing salt. Desalinization machines produce fresh water by removing the salt from seawater. The importance of fresh water on a ship at sea cannot be overstated. Fresh water is essential to the crew of the Dyson for drinking, food preparation, waste management, and washing. Fresh water is also used to remove the heat from the generators in the engine room and to cool living spaces throughout the ship. The generators give off so heat much in fact there is never a shortage of hot water for the crew!
The desalinization machine
After touring the engineering spaces of the Dyson, I was surprised to see several work stations comprising of work benches and many hand tools dedicated to servicing equipment and fabricating new parts while at sea. Any one of these machine shops would satisfy any suburban Mr. Fix-it! In addition to these work stations, the Dyson also has numerous storage cabinets and cubby holes located throughout the ship storing everything from screws and zip ties to transistors and electronic circuit boards. The extent to which technology has permeated the Dyson is revealed by the maze of wires found overhead in every room and passageway. The many wires and pipes snaking from one room to another remind me of a giant circulatory system. The Dyson has two rotating Electronic Technicians, Vincent Welton and Stephen Macri, and an Engineering Electronics Technician, Terry Miles, whose job is to keep all these technologically advanced electronics in good working order.

One of my favorite places on the Dyson is the bridge. The bridge of the Dyson is the command and control center for the entire ship. The bridge not only allows the NOAA Corps officers to safely navigate the Dyson but allows communication with the entire ship, nearby boat traffic, and the shore. Utilizing radar, electronic charts, magnetic compasses, GPS, sonar, advanced radio and communication equipment, and various weather instruments, the bridge provides a wealth of information at one’s fingertips. The OOD (Officer of the Deck) carefully monitors the numerous screens and readouts on the bridge control panels and keeps a sharp eye on the surrounding seas. While I have become familiar with several of the main systems on the bridge and can deduce a great deal about the Dyson’s current location and movement, I recognize there is much to learn to safely navigate and operate the ship. I am comforted when resting in my rack knowing there are skilled and experienced hands on the bridge 24 hours a day!
Ensign Payne maneuvering from starboard control station
Located five stories above the water, the bridge has a fantastic view. The bridge is wide and open and has windows in every direction. The bridge provides a great view of the operation of the ship and the surrounding seas. I am most impressed with the layout of the bridge. The ship can be controlled from any one of four stations located around the bridge. The bridge is laid out like a capital T: a central control station located in the middle of the bridge, a station positioned on both the port (left) and starboard (right) sides of the bridge, and a station located aft (back) facing the rear of the ship. This allows the OOD to pilot the vessel while keeping a close eye on deployments/operations being conducted anywhere on the Dyson. For example, when conducting an Aleutian wing trawl off the stern (back) of the vessel, the OOD can transfer control to the aft station and pilot the Dyson while facing backwards!
In addition to the view, the bridge is also fun to visit as there is always someone to talk to and usually fun music playing quietly in the background. Recently, I have enjoyed watching the bow crash through 15-20 foot waves as we continue running each transect of our acoustic trawl survey.

While the weather continues to make deployments challenging, we have still managed to fish a few times. Interesting bycatch from these trawls includes seastars and brittle stars from the Tucker trawl and Pacific cod and sturgeon poacher from the Aleutian wing trawl.

Did you know?
The summer solstice marks the longest day and the shortest night of the year. The word solstice comes from the Latin word ‘sol’ meaning ‘sun’ and the word ‘stice’ meaning ‘to stand still’. As summer days lengthen (meaning the sun rises earlier and sets later each day), the sun’s path through the sky takes the sun higher and higher above the horizon forming a greater and greater arc. At a certain point, the sun reaches its highest point. At this point the sun seems to stand still before slowly falling back to the horizon with each passing day. This point when the sun reaches its highest arc in the sky is called the summer solstice. The earth’s tilt on its axis causes the sun to travel slightly different paths through the sky each day and causes the sun’s rays to fall with varying intensity on different regions of the earth. Over the period of one year (one orbit of the sun by the earth), this variation in sunlight explains why the earth has four seasons: summer receives the most direct rays, winter receives the least direct rays, and spring and fall are times of transition between these two extremes. The summer solstice always falls around June 21st in the northern hemisphere (above the equator). With the Dyson surveying southeast of Pribilof Islands in the Bering Sea, the sun will rise at 6:30 AM and will set at 11:50 PM on June 21st. If you were standing at the North Pole during the summer solstice, you would experience 24 hours of sunlight (the sun would never dip below the horizon!) while 24 hours of darkness would be observed at the South Pole.

Science and Technology Log
The Research Vessel Hugh R. Sharp finally made it into port this morning at the National Marine Fisheries Service in Woods Hole on the Cape Cod coast of Massachusetts. Although this cruise was not terribly long it is great to be back on land. Scallop surveying is tedious work that is ongoing on a research vessel 24/7. The people onboard were great to work with and it is always a pleasure to get to know other people, especially those who share a passion for ocean research and science. Few people realize the great effort and sacrifices that people in the oceanography field have to give up to go out to sea to complete research that will help give a better understanding to three-fourths of the planet’s surface. They must leave home and loved ones for many days to get the science needed for a more complete understanding of the Earth’s oceans.
The noon to midnight shift includes myself, the Chief Scientist onboard, Stacy Rowe, watch chief Jakub Kircum, Shad Mahlum, Francine Stroman, and Joe Gatuzzi. We are responsible for sorting each station on our watch, measuring and weighing the samples into the computer. These people are very good at what they do and quite dedicated to performing the task with professionalism, courtesy, and a great deal of enthusiasm. It is clear to see that each person has a passion for ocean sciences especially the fisheries division. The NOAA fisheries division carefully surveys and provides data to those that make regulations about which places will be left open for commercial fishing and those which will be closed until the population is adequate to handle the pressures of the commercial fishing industry. I have observed many different species of marine animals, some of which I did not even know ever existed. Below is a photo of me and the other TAS Duane Sanders putting on our survival at sea suits in case of emergency. These suits are designed to keep someone afloat and alive in cold water and are required on all boats where colder waters exist.
The Goosefish, also called Monkfish, is a ferocious predator below the surface and above!
Personal Log
The fish with a bad attitude award has to go to the goosefish. This ferocious predator lies in wait at the bottom of the ocean floor for prey. On the topside of its mouth is an antenna that dangles an alluring catch for small fish and other ocean critters. When the prey gets close enough the goosefish emerges from its muddy camouflage and devours its prey. I made the error of mistaking it for a skate that was in a bucket. I was not paying close enough attention as I grabbed what I thought was the skate from a bucket, the goosefish quickly bit down. Blood oozed out of my thumb as the teeth penetrated clean through a pair of rubber gloves. I pay closer attention when sticking my hand in buckets now. There are many creatures in the sea that are harmless, but one should take heed to all the creatures that can inflict bodily damage to humans.

Science and Technology Log
The bridge of a ship is a very busy place where all activities that are occurring on the ship being managed from this location. When any equipment is going overboard it is the responsibility of the captain or first mate to ensure that it is done safely and correctly. The ship must follow a predetermined route for each stations sampling and be kept on tract by precise navigating from the bridge. Whenever anything goes overboard the bridge has to be notified, it is important for the bridge to know everything that is in the water to avoid the boat from being fouled up by miscellaneous line in the water. This could be dangerous and costly for the ship and crew.

Captain Bill Byam has been very helpful to me and my fellow teacher at sea making sure we have the availability of the crew and ship to write our journal entries and then submit them online to NOAA. The ship’s crew is also responsible for deployments and retrieving of all instruments put overboard the ship. Along with the dredge and occasional CTD is deployed to get a profile of the water column and collect water samples at varying depths. The water samples can be used for a variety of things, such as water filtering to see what microscopic critters may be present, chemical analysis, as well as conductivity or salinity of the water. The CTD is standard instruments used on most science research vessels. The crew on the Sharp are very proficient, professional, and hard working as they also help with assisting the scientist with some of the work on deck.
Personal Log
Shad and Stacy repair the net on one of the dredges
The cruise has gone very smoothly with lots of scientific data have been collected for future analysis. I have worked closely on the deck with members of the noon to midnight shift for almost two weeks. In that time we have collected many samples of scallops, crabs, starfish, sand dollars, sea urchins, many varieties of fish, and even occasional pieces of trash left from man’s misuse of the ocean. I hope to be able to take the knowledge gleaned from this experience and the scientist onboard the ship and give my students back in Oklahoma a better understanding of our oceans and how their health impacts everyone around world even those in land-locked Oklahoma. It has been my goal to better inform my 5th-8th grade students, my college students who are training to become teachers, and the general lay member how all of us impact the health of the oceans and how important the oceans are to us all in maintaining a homeostatic balance with the Earth’s biosphere and atmosphere. We all have much to gain with a healthy ocean system and much more to lose if we are not adequate in our stewardship of our oceans.
I would like to give a special thanks to Chief Scientist Stacy Rowe for allowing me to participate in all aspects of the cruise and collecting samples. The team I am with are very cordial and extremely helpful in answering all my questions. They made me feel a part of the team and not an outsider. It was great to work with a group of people who are so dedicated. When one team member finished a task they simply moved to help another team member until the whole catch was sorted, measured, and weighed. It is good to work with people who are equally vested in their work. No one person stood and watched as others worked, each did an equal share of the work and made sure the task was completed in a timely and organized fashion. This made the long hours of the shift seem shorter and the days went by much quicker. It is always good to be a part of a good team. Thanks to the crew aboard the Sharp, and the scientist that made this trip a profitable one, not only for me but also for my students back in Oklahoma. Thank you Bill Byam, captain aboard the Sharp and all of his dedicated crew. The ship’s crew, were hospitable host and I really enjoyed meeting you all. Thanks to NOAA for allowing a previous teacher at sea another opportunity to learn more about the oceans and have another lifetime memory to share with others.

Science and Technology Log
There is a lot of sophisticated equipment aboard a science research vessel of today. Shad who is one of the scientists aboard the ship explained to me how they used to do scallop surveys on older ships just a few years ago. Then they would catch scallops using the dredge net that was then hauled onboard and dumped on the deck. The scientist would then get on their hands and knees and sort through the pile for scallops or whatever they were looking for. The pile would have to be scoured twice to ensure everything was accounted for. There was a lot of shoveling and moving of the pile as things were being sorted. The work was long, dirty, and backbreaking.
Today the Sharp has a sorting table onboard which makes the job much easier and gives the ship and crew the availability of adding more stations to the survey and getting much more work done than in past seasons. Below is a photo of a magnetic measuring board. The scallop or fish are placed on the board and a magnetic wand is put at the end of the sample where an accurate measurement is made and placed into the computer showing the size of the sample. This process is much faster than measuring and recording by hand. They are also weighed in large baskets to determine average weight of the catch.

Scallops opening in the warm sun!
Some days have been very long at times yet fruitful. A week has passed and we have collected thousands of scallops, hundreds of thousands of starfish, and many other species of bottom dwelling fishes and animals. I have observed many varieties and species of animals that I have never seen before except on TV or in a textbook. This hands-on experience will leave an indelible picture in my mind for many years of what research life is like onboard a research vessel. There are many dedicated scientist and crewmembers in NOAA fisheries that are insuring the viability of certain species so that commercial fishing does not over fish areas of our oceans.
These scientists do valuable research in the labs around the United States but also go out on research vessels and get their hands dirty, work extremely hard, and commit a large part of the personal lives to preservation of species in our oceans so that future generations can enjoy the wide diversity that our oceans provide for us today. NOAA has scientist working all around the oceans of the United States as well as other parts of the world to give science a better understanding of the vital role each species has in its environment and how that species overpopulation or disappearance could impact the immediate area, larger habitat of the ocean, and the world as a whole. I feel more at ease knowing that there are dedicated people in the world ensuring not only the interest of humans but are also advocating for all species. The diversity on earth is better understood every year giving scientist and the general public a better understanding of each species role on the world stage of life.

Science and Technology Log
The crew is busy collecting scallops. Occasionally between tows, the crew shuck scallops to eat onboard, this is allowable in open areas. A meal of freshly shucked scallops will be enjoyed by those onboard the ship. Shucking scallops is a skill that can be learned over several days. A long curved skinny knife is inserted between the shells and part of the scallop is cut away from the shell. With a little skill one more quick cut of the knife and all the inside parts of the scallop are whisked away leaving behind a cylinder shaped piece of white meat that is the part of the scallop enjoyed by people around the world.
TAS Duane Sanders (left) is busy sorting scallops while others shuck the scallops (right).
Some dredges produced scallops exclusively, while others produce very few scallops and lots of starfishes or sand dollars. Scientists are trying to understand the dynamics between the starfish and scallop populations as well as other species. Getting rid or over fishing one species can have a profound effect on other species especially if that species is considered a keystone species in that particular environment.
The R/V Hugh R. Sharp (Lewes, Delaware)
Personal Log
The Research Vessel Hugh R. Sharp is one of the newer ships in the fleet of research vessels along the Atlantic coast. The ship is 146 feet long with state of the art equipment onboard to help it complete missions vital to ocean research. It cost about $14,000 dollars a day to keep the ship doing research while at sea. The ship is very versatile and has completed a varied amount of differing research cruises along the east coast of the United States. I am amazed at how quiet the ship is when running. I have been on two other research vessels, and they were much louder when underway. The Sharp has diesel engines that run electric motors making it run much quieter and smoother than other research ships. The ship will also turn on a dime usually it takes quite of bit of time and space to turn a ship around. This is not true on the Sharp it will turn very quickly due the bow thrusters onboard the ship. The ship may be smaller than many research vessels, however it is versatile and efficient when conducting research along the Atlantic coast.
The crew which are captained by Bill Byam are well trained and prepared for the task required of them to make sure the science is completed in a timely manner and efficiently for the scientist aboard. I have found working with the crew to be an enjoyable experience. The food onboard is superb, Paul is a great cook and prepares unique dishes for every meal and is also an avid fellow soccer fan.

Science and Technology Log
The sorting table is full of activity as soon as the dredge is pulled aboard the ship. After the crew secure all lines and dump the load the volunteers and scientist begin to sort through the biological that has been brought up from the bottom or the Atlantic Ocean. Each dredge can bring a varied amount of sea life on the ship. We are always looking for scallop, yet every third dredge we also sort for crabs. All fish are also sorted and counted.
After all the sorting is done the fish, scallops, and crabs are weighed and measured for length. They are then logged into the onboard computer for analysis of results for each catch. We are trawling along closed areas for scallops. These areas have been closed for commercial fishing to ensure that the population has time to recover in that area. Scallop surveys are carried out by the R/V Hugh R. Sharp, in three phases during the summer. Duane and I are on the second leg, which encompasses the area to the east of Delaware, areas around Long Island, and the area around Martha’s Vineyard south of Cape Cod, Massachusetts.
Personal Log
You may find some interesting creatures during sorting.
The work aboard the ship can be very long and laborious. The days are long, as each member of the cruise will do a 12-hour shift. My shift is from noon to midnight. The conditions can vary greatly during a shift. During the day the sun may be out with light winds and it gets very warm with all the wet weather gear that is worn during sorting. It is necessary to leave the gear on between dredges, since they occur so often. As soon as the sun goes down the temperatures can drop very rapidly. It is important to keep a hooded sweatshirt and other warm weather gear nearby for the changing conditions. All gear must be taken with you when you leave your cabin so that the other shift can sleep uninterrupted. The days are long, with the goal of all who are onboard to get the science completed in a timely fashion. Keeping a ship stored with goods and running is very expensive so the goal is to get as much science completed in the allotted time as possible.
Question of the Day
What other bottom dwelling species in the Atlantic are under protection from over-fishing?
Animals Seen Today
Scallops, eels, crabs, starfish, clams, silver dollars, urchins, goose fish, and many varieties of bottom dwelling fish.
