Measuring Atlantic Bluefin Tuna with a Drone

June 10, 2020 — This novel use of drones is a promising way to remotely monitor these hard-to-see fish

Researchers have used an unmanned aerial system (or drone) to gather data on schooling juvenile Atlantic bluefin tuna in the Gulf of Maine.

This pilot study tested whether a drone could keep up with the tuna while also taking photographs that captured physical details of this fast-moving fish. The drone was equipped with a high-resolution digital still image camera. Results show that drones can capture images of both individual fish and schools. They may be a useful tool for remotely monitoring behavior and body conditions of the elusive fish.

Individual fish lengths and widths, and the distance between fish near the sea surface, were measured to less than a centimeter of precision. We used an APH-22, a battery-powered, six-rotor drone. The pilot study was conducted in the Atlantic bluefin tuna’s foraging grounds northeast of Cape Cod in the southern Gulf of Maine.

“Multi-rotor unmanned aerial systems won’t replace shipboard surveys or the reliance on manned aircraft to cover a large area,” said Mike Jech, an acoustics researcher at the Northeast Fisheries Science Center in Woods Hole, Massachusetts and lead author of the study. “They have a limited flight range due to battery power and can only collect data in bursts. Despite some limitations, they will be invaluable for collecting remote high-resolution images that can provide data at the accuracy and precision needed by managers for growth and ecosystem models of Atlantic bluefin tuna.”

WHOI Scientists Studying Phytoplankton to Improve Satellite Operations in Space

November 26, 2018 — WOODS HOLE, MASS. – Researchers from Woods Hole are working to improve the quality of data collected by satellites over 500 miles above the ocean.

The goal is to determine how microscopic algae, also known as phytoplankton, absorb and scatter light, and how the colors of the phytoplankton can be better identified and measured.

For the next three years, researchers from NOAA Fisheries and colleagues at the University of Rhode Island, NOAA’s National Environmental Satellite, Data and Information Service, and Woods Hole Oceanographic Institution will look into the ocean to help improve the quality of data collected by satellites more than 500 miles above.

NOAA site aims to help fishing communities bounce back

November 24, 2017 — NOAA Fisheries has introduced a new website designed to help fishing communities be more resilient in the face of climate change, fluctuating fish stocks and even declines in waterfront infrastructure and economy.

The new website endeavor, introduced this week after almost three years of planning, is called Community Resilience in the Greater Atlantic Region.

“It really came out of the strategic plan we developed here in the regional office, which was the first one anywhere,” said Peter Burns of NOAA Fisheries in Gloucester. “One of the goals of that plan centered on building community resilience to help strengthen fishing communities.”

Working with NOAA’s Northeast Fisheries Science Center in Woods Hole, the community resilience working group — which included NOAA staffers from the West Coast, as well — began exploring ways to assist fishing communities in coping with regulatory, environmental and economic changes that challenge the very sustainability of fishing communities.

According to NOAA Fisheries’ own description of the endeavor, the resiliency strategy would provide information on “solutions to improve groundfish business practices and economic vitality,” as well as incorporating climate change, ocean acidification and ecosystem analysis into NOAA Fisheries’ activities.

WHOI Led Research Team to Develop System to Predict Changes in Ocean Temps

October 30, 2017 — WOODS HOLE, Mass. — A research team led by the Woods Hole Oceanographic Institution has received a federal grant to develop a system to predict changes in ocean temperature.

The system will estimate seasonal and year-to-year temperature changes in the Northeast U.S. Shelf, which is seeing some of the highest ocean warming rates in the world and is home to a highly productive and commercially important marine ecosystem.

The Northeast Fisheries Science Center in Woods Hole and Stony Brook University are also part of the research team.

“Changes in ocean temperature hugely impacts the living organisms in coastal waters,” said Young-Oh Kwon, an associate scientist in WHOI’s Physical Oceanography Department and lead investigator of the new project.

MASSACHUSETTS: Seals die within days of each other at Woods Hole Aquarium

July 14, 2017 — The Woods Hole Science Aquarium is mourning the loss of its two beloved harbor seals, Bumper and LuSeal.

They died within 11 days of each other, and the causes of their deaths are unknown, officials said. The aquarium announced that it would be closed Friday and Saturday to allow time for the staff to recoup.

The two seals came from different states — LuSeal was stranded on Cape Cod in 2002 when she was just a month old, and Bumper was found on a South Hampton, N.Y., beach after being wounded by a shark in 2007 — and fate led them to live together at the aquarium’s modernized seal habitat, where they swam, ate, and sunned themselves, as seals are wont to do.

Marine scientists use drifters to explore regional currents

June 27, 2017 — We know Clint Eastwood was the High Plains Drifter. And we’ve heard Bob Dylan’s tale of the Drifter’s Escape. But now the Northeast Fisheries Science Center in Woods Hole is employing drifters not on the plains but on the waves around Cape Cod and the Gulf of Maine.

“I’m excited about our latest drifter project,” proclaimed NMFS Oceanographer Jim Manning. “It’s one of many we’ve had and it seems like a real application for drifters. We’ve used them for a lot of fun educational purposes but our recent project in the Bay of Fundy has real purpose.”

They’ve been used with purpose in Cape Cod Bay as well. But, you might ask, what exactly is a drifter? It’s not a shiftless character begging at the kitchen door for scraps.

“It looks like an underwater kite, like a box kite,” Manning explained. “It’s a meter by a meter of cloth sails and they only thing that sticks out is a satellite transmitter. It provides us an estimate of the surface current.”

Its function is similar to that of a glass bottle with a note in it. You toss it in the ocean, it drifts somewhere, and you find out where it went.

With the old bottle you had to wait months or years until someone wrote back but a transmitter can tell you where it is today. It reveals where the surface currents are headed and can tell you where anything drifting along, like a cold-stunned sea turtle in Cape Cod Bay, or a swath of toxic algae in Maine, might wind up.

The current project Manning is excited about focuses on Alexandrium fundyense, the plankton that causes paralytic shellfish poisoning in anyone that eats a shellfish, usually a clam, that has filter fed on it. It’s the same algae that lives in the Nauset Marsh between Orleans and Eastham, and causes annual shutdowns of shellfishing harvests.

The plankton has a resting stage where it sits as cysts in the mud. When conditions are right and the water warms the cysts germinate, it swims up towards the surface and the currents carry it away. In Nauset Marsh it doesn’t go far and stays in the marsh but in the Bay of Fundy it’s carried down the coast.

“The main objective is to help numerical modelers try to simulate the ocean,” Manning said. “A couple of universities have big computer models. These models are used for a variety of things. We’ve deployed the drifters north of Grand Manan Island up in the Bay of Fundy to demonstrate how complicated the currents are. Every time we put one out it goes in a different direction.”

Fisheries scientists teach science of marine mammals to Woods Hole-area elementary students

January 26, 2017 — New England has a rich maritime tradition, with the livelihood and leisure activities of many residents associated with the ocean in some way. The NOAA Outreach and Education on Protected Species (NOEPS) program strives to build connections between NOAA Fisheries science and local communities, enriching and supplementing the current science program. In order to achieve a significant impact in nearby small communities, the NOEPS program targeted all K-4th grade classrooms in the Falmouth Public School District.

In its third year, NOEPS gave classroom presentations to 10 schools in the New England area. The program, based out of NOAA Fisheries’ Northeast Fisheries Science Center (NEFSC) in Woods Hole, Massachusetts, reached 1,790 students in 95 classrooms from preschool to high school in the 2015-16 school year. Educators had expressed a need for hand-on activities to engage students so the Northeast Fisheries Science Center designed a program to enrich and supplement the current science program as well as bring in marine science at the elementary level. Presentations focused on key marine mammal species and research conducted by NEFSC scientists, offering free one-hour lessons with hands-on activities, presentations, and projects on marine mammals for K-6 classrooms, and emphasizing the conservation and stewardship goals behind the science. In 2015-16, the program expanded to include K-3 classes in the Mashpee School District. In addition, NOEPS lessons and core educational materials are available for download by teachers.

NOAA science director steers a new course

January 30, 2017 — It was last Halloween when Jon Hare took over as Science and Research Director for NOAA’s Northeast Fisheries Science Center in Woods Hole. He was aware he was jumping into a cauldron but it hasn’t spooked him yet.

“I knew it was going to be a challenge and that’s why I was interested in it,” the career NOAA scientist said.

Hare does understatement well.

The director’s job description includes managing “the living marine resources of the Northeast Continental Shelf Ecosystem from the Gulf of Maine to Cape Hatteras,” according to the NOAA website.

If that in itself were not sufficient, these resources include commercial fisheries, and in New England that is synonymous with controversy.

Federal fishery management in general, and the efficacy of NOAA’s survey work on fish stocks in particular, have been heavily criticized by fishermen in the Northeast, almost without cessation for the past 15 years and the NEFSC has been at the sharp end of much of this disaffection.

Since his appointment Hare has launched himself upon these troubled waters with energy and candor, reaching out to industry stakeholders at every opportunity in the belief that there is common ground.
