Science and Technology Log

Stacy Rowe, of the Northeast Fisheries Science Center, in Woods Hole, Massachusetts is the Chief Scientist for our cruise. I had a chance to talk with her about her background, experiences, and job while we were waiting to leave port today.

When working onshore, Rowe is responsible for pre-cruise preparations, such as ordering supplies for the trip and coordinating the collection of special samples for in-house and out-of-house scientists. She also works on testing a new version of FSCS (Fisheries Scientific Computer System), which is the system we are using to collect data about the fish populations.

During the cruise, when serving as Chief Scientist, Rowe shoulders a lot of responsibility. She schedules the watch teams, works with both watch teams, and acts as a liaison between the scientists and the ship’s personnel on the bridge (the room from which the boat is commanded). Although the sampling stations are randomly selected via computer before the cruise, Rowe works with the bridge to determine in which order stations will be sampled. On this cruise she has consulted with the bridge often because the weather has impacted our travel so much. Rowe relates that the job of chief scientist is mentally tiring because she is really on call the entire cruise. After the cruise, Rowe works with post-cruise management. She makes sure the samples collected are distributed to the scientists, and she audits data to make sure there were no errors in data collection.

Rowe grew up in Florida and attended the University of Florida where she earned a BS in Natural Resource Conservation with a minor in Wildlife Ecology. During her undergraduate program, she studied sampling, and uses this information extensively in her job now. After she graduated from college, Rowe joined the Peace Corps. She spent over one year working in Congo, Africa on a fresh water project. Then, she spent two years on Palau in Micronesia working in marine resource management. Rowe has been with NOAA for eight years, now. She goes on five to six research cruises a year, which adds up to about sixty days for the entire year. She serves as Chief Scientist on the majority of her cruises, but still enjoys the rare cruise when she works as a scientist processing catches.

Rowe has some advice for young people thinking they might like a career like hers. First, get a degree in any science area. A marine science degree isn’t really necessary. Work experience is the really important key. Second, volunteer as much as you can. Volunteering to work on research cruises not only builds a resume, but it allows students to try it out early on in their school career to see if they like it.

Stacy Rowe has strong interpersonal and organizational skills that are important for her leadership position, and I’ve enjoyed working as a volunteer scientist under her direction.

Personal Log

Newport, Rhode Island is a great place to visit. It was a center for shipbuilding and trade during colonial times, and is the birthplace of the U.S. Navy. Some of the United States’ wealthiest families built summer homes overlooking the bay, and these homes are open for tours today. I spent a nice afternoon on the “Cliff Walk” which is a trail that skirts around the edge of the estates just above the water. I had been there twenty five years ago, so it was fun to revisit the area.

Narragansett Bay
Narragansett Bay.

After two days in port, we are heading back out to sea. It’s a beautiful day. The sun is shining, and the waters are pretty calm. It’s hard to believe that we will be in rough waters once we leave Narragansett Bay. I’m riding up on the weather deck as we leave the bay, and I see many sailboats, two commercial cruise liners, Fort Adams (which has guarded Narragansett Bay since Colonial Times), Clingstone (a famous house built on a rock in the water), and the Newport (Pell) Bridge. I’m definitely putting Newport on my list of places to revisit.

Processing an Atlantic Spicy Dogfish

We have processed Atlantic Spiny Dogfish in the lab this week. This fish isn’t very popular for food in the United States, but it is exported to Europe for “fish and chips.” In 1998, this species was overfished, therefore, there were limits placed on the numbers fisheries could catch. Since that time, catch levels have been rebuilt.

The Atlantic Spiny Dogfish lives a long time: females up to 40 years and males up to 35 years. Females are larger than males and give birth to between two and fifteen live pups. During gestation (18-24 months) the pups have a yellow sack at their necks called a “yolk.” The Spiny Dogfish, processed here by TK, was a female with six pups. You can see the yolk on the two pups in the picture at right.

Acoustics: Lisa Bonacci, chief scientist, and Melanie Johnson, fishery biologist, are in the acoustics lab onboard the Miller Freeman as it travels along a transect line. NOAA scientists can detect a variety of marine life under the sea. They use sonar—sound waves bouncing off an object—to detect the animals. There is an onboard sonar system that puts out four different frequencies of sound waves.  Each type of fish will give off a different signal depending on its size, shape, and anatomy.  The fish are then identified on the sonar computer readout.  The strength of the sonar signal will determine the number of hake and the way that they are swimming.  As soon as it appears on the sonar as if hake are present, Ms. Bonacci then calls the bridge to request that we trawl for fish.

This is the sonar readout as it’s seen on the computer screen.

Personal Log 

The boat was rocking in all directions with 40 knot winds and 8-10 foot waves. The fishing trawl brought up scores of fish including a lot of hake. The sonar signals worked really well to locate them. We dissected and measured many fish, but not before we sat in a giant vat of hake (see photo.)  It was a great learning day.

Animals Seen Today 
Hake,spiny dogfish, Humbolt squid, Myctophidae, and Birds.

Here we are in a giant vat of hake!

Discovery from the Briny 
As the trawl net was raised from the depths
The sun broke through the clouds revealing a sparkling azure sky.
Scores of seagulls circled the stern
In the hopes of a bountiful offering
Tasty morsels from the deep
Soon to be thrown overboard.

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.

lawrence_log6The 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.

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.
