Anticipating the winds of change: A baseline assessment of Northeastern US continental shelf surficial substrates
The introduction of thousands of wind turbines along the North American Atlantic continental shelf over the next decade will constitute the largest regional change in marine substrates since the retreat of the Laurentide Ice Sheet over 14,000 years ago. Here, two large data sets, SMAST drop camera survey (242,949 samples, 2003 to 2019) and the US Geological Survey databases (27,784 samples, 1966 to 2011), are combined to derive sea floor surficial substrate probability maps for the Northeastern US continental shelf from Virginia Beach to the Gulf of Maine to 300 m depth (218,571 km2). Geostatistical models were used to estimate the probability of five geologic and one biogenic substrate types being present at a 250 m resolution, and the proportional contribution of each substrate type to the seabed composition at a 500 m resolution. By providing the first synoptic maps depicting the probability of a particular substrate or combination of substrates occurring at any location on the Northeastern US continental shelf, including planned wind energy sites, we aim to (1) provide insights regarding how substrates in the areas selected for wind energy development compare with other locations, (2) motivate the development of a priori expectations for ecosystem changes to inform monitoring and research efforts going forward, and (3) to provide a baseline characterization of the Northeastern US continental shelf surficial substrates to support robust examination of the future changes observed in areas impacted by wind energy installations. more, >>CLICK TO READ<< 11:44
Ropeless fishing gear: Georgia researchers work with commercial fishermen to test equipment
NOAA has identified two areas critical for right whales: off the coast of New England, where the whales forage for food in warmer months; and off the southeast coast from North Carolina to Florida, where the whales reproduce between November and April. Fluech is collaborating with Kim Sawicki, project lead and doctoral student at the University of Massachusetts,, In summer 2020, the research team secured a permit from the National Marine Fisheries Service to test eight different ropeless gear systems with black sea bass pots off the coast of Georgia. It was the first time the ropeless gear had been tested in the South Atlantic. >click to read< 08:37
Gloucester – Fishermen, scientists to assess stock
The most incendiary divide between groundfishermen and fishing regulators in the past two years has been the discrepancy between what NOAA Fisheries says its stock assessments show and what fishermen are seeing on the water. The groundfish assessments by the National Oceanic and Atmospheric Administration — particularly for the iconic Gulf of Maine cod stock and certain flounders — have been uniformly dire, leading to the virtual shuttering of cod fishing in the Gulf of Maine and scant quotas for other species. Fishermen — including commercial groundfishermen, charter captains and even lobstermen — paint a very different portrait of what they are seeing on a daily basis: cod, cod everywhere, and not a one they can catch. On June 20, the city’s Economic Development and Industrial Corporation and fishing stakeholders will host a presentation by a team of University of Massachusetts scientists on their current findings and methodology for fish population counting in the Gulf of Maine.

Study: Leatherbacks stay near Cape
With a blunt nose and arched shell, up to 8 feet in length and weighing 2,000 pounds, a leatherback turtle is the marine equivalent of a Volkswagen Beetle. Propelled through the water by enormous front flippers, leatherbacks,, Read more here capecodonline 05:23
