Computers Now “See” Animals on the Ocean Bottom

September 8, 2020 — The following was released by NOAA Fisheries:

The Northeast Fisheries Science Center’s annual sea scallop research survey uses a towed sampling device called the HabCam. It collects approximately 5 million images of the ocean bottom off the Northeast United States. Scientists and volunteers then manually examine an astonishing 100,000 of these images, roughly 2 percent of the number gathered. They focus on identifying just four targets: sea scallops, fish, crabs, and whelks.

So, a wealth of data is going uncollected owing to the sheer volume available and just how labor-intensive pulling it out of images can be.

Researchers have turned toward finding ways for machines to help identify sea life in these images, faster and more efficiently than humans can. This would improve population data for sea scallops. By more thoroughly examining each image, all kinds of information about other sea life and their habitats can also be captured.

Enter Dvora Hart, an operations research analyst at the Northeast Fisheries Science Center. Hart has been at the forefront of estimating sea scallop populations numbers from images taken by devices like the HabCam. The upcoming 2020 sea scallop assessment will once again use improved population data collected from images.

“HabCam gives us photos of animals in their natural environment without disturbing them; however, much of the information in the images is not collected because human annotators can only mark a small percentage of the available images,” said Hart. “Automated annotators can mark all the images and, given proper training, can identify a multitude of different targets—not just sea scallops, fish, crabs and whelks.”

Hart is part of an interdisciplinary team that developed the world’s first advanced automated image analysis software for the marine environment. The Video and Image Analytics for the Marine Environment, VIAME for short, uses convolutional neural networks—a recent advance in artificial intelligence. These networks  teach computers to recognize species and features of their habitats in the images taken by the HabCam.

The work is so significant that Hart and her team won a 2019 Department of Commerce gold medal for their work. This recognition is the highest honor award offered to department employees.

Do River Channels Always Change When Dams Are Removed? It Depends

September 8, 2020 — The following was released by NOAA Fisheries:

Dams are constructed for many purposes, including energy generation, water supply, flood control, and recreation. Dams can also impact the environment, both when they’re built and again when they’re removed. Researchers from the University of Maine, U.S. Geological Survey, and NOAA collaborated to determine what happens to the shape of rivers when a dam is removed. They found that the changes can be minimal under specific geologic and site conditions.

Seeking Nominations for Candidates for the Marine Mammal Atlantic Scientific Review Group

September 4, 2020 — The following was released by NOAA Fisheries:

NOAA Fisheries published a Federal Register Notice on September 3, 2020 soliciting nominations to three independent marine mammal scientific review groups.

The three independent regional scientific review groups, covering Alaska, the Atlantic (including the Gulf of Mexico), and the Pacific (including Hawaii), were established under section 117(d) of the Marine Mammal Protection Act to provide advice on a range of marine mammal science and management issues.

We would like your assistance to identify qualified candidates for the Atlantic (including the Gulf of Mexico) review group. We are seeking individuals with expertise in one or more of the following priority areas (not in order of priority): Protected species conservation, wildlife management, and policy/science interface especially in the non-governmental sector; line-transect methodology, mark-recapture methods, survey design, and quantitative ecology; life history and ecology, particularly large cetaceans and delphinid species; Gulf of Mexico cetacean population dynamics; Southeast U.S. cetaceans; Northeast U.S. Large Marine Ecosystem (LME); marine mammal health, physiology, energetics, and toxicology; genetics; fishing gear and practices, particularly fisheries with marine mammal bycatch, fishery bycatch estimation, and bycatch reduction; ecosystem climate impacts; and manatees.

As you consider nominating candidates, please remember

  • A Scientific Review Group member cannot be a registered Federal lobbyist or foreign agent;
  • Service is without pay, except for reimbursable travel and related expenses; and
  • Individuals serve for a term of three years, for no more than three consecutive terms if re-appointed.

Nominations are due by October 5, 2020.

Maine lobster industry nets $2 million for research

September 3, 2020 — For the second straight year, $2 million has been awarded for lobster research in the Gulf of Maine. Four of the nine NOAA Sea Grant projects will be conducted by Maine organizations, totaling $559,181 in funding for Maine-based research projects.

Sen. Susan Collins (R-Maine), a senior member of the Appropriations Committee, announced the Sea Grant American Lobster Initiative funding on Thursday, saying, “This critical federal funding will build on their efforts to support the health of Maine’s lobster fishery and help ensure its continued success.”

The $2 million will support Gulf of Maine and Georges Bank American lobster research priorities, which is aimed at understanding how environmental changes are affecting American lobster in the Gulf of Maine.

NOAA to boaters: Watch out for right whales

September 2, 2020 — Federal fisheries regulators are asking mariners to either go slow or find a route around an area south of Nantucket where groups of right whales have recently been spotted as the endangered mammals migrate.

The National Oceanic and Atmospheric Administration said it established a “dynamic management area” south of Nantucket where “an aggregation of right whales” was seen on Monday. There are estimated to be fewer than 400 right whales remaining on Earth. Boaters are encouraged to slow their vessels to 10 knots or less or to avoid the area altogether.

Pink Salmon May Benefit as Pacific Arctic Warms

September 1, 2020 — The following was released by NOAA Fisheries:

The Pacific Arctic is undergoing a rapid transformation. As temperatures rise and sea ice melts, some species will do better than others. A new study suggests that pink salmon may be one of those species.

“Our results suggest that warming is both increasing freshwater habitat and improving early marine survival of pink salmon in the northern Bering Sea,” said Ed Farley, NOAA Fisheries biologist at the Alaska Fisheries Science Center, who led the study.

The study provides insight into the response of pink salmon to climate change. The findings are valuable information for commercial and subsistence fisheries, and fishing communities, preparing for future changes.

“Subsistence harvesters would like to know what foods may be available to them now and into the future,” Farley said.

“The importance of fish in Arctic subsistence economies cannot be overstated; they are some of the most commonly eaten foods,” said coauthor Todd Sformo, biologist at the North Slope Borough Department of Wildlife Management.

“In the past on the North Slope, salmon have been used for dog food and even considered nuisance fish when interfering with preferred species such as aanaakliq or broad whitefish in the inland rivers. Recently, there seems to be a change both qualitatively and quantitatively in the use of salmon as a main dish and for smoking.

“Participating in this study allowed me to present a subsistence perspective, learn how fellow researchers measure production dynamics, and better understand how pink salmon are responding to climate warming in the northern Bering Sea. While this research is further south than the waters surrounding the North Slope, it is a beginning of our attempt to account for potential change in subsistence fishing.”
