11.1.3 Project description

The standardized NEFSC Fall Bottom Trawl Survey was initiated in 1963 and covered an area from Hudson Canyon, NY to Nova Scotia, Canada. Throughout the years, coverage has extended as far south as Florida and sampling depths have ranged from <27 to 366 m. Currently, the survey coverage is from Cape Hatteras, NC to Nova Scotia and the minimum depth range is > 18 m as the result of a change in the sampling platform. This has resulted in the exclusion of many inshore strata.

Currently, the survey coverage is from Cape Lookout, NC to Nova Scotia, including Georges Bank and the Gulf of Maine. The depth range minimum is >18 m, as the result of a change in the sampling platform. This has resulted in the exclusion of many inshore strata.

11.3.3 Project description

Sampling the coastal waters of the Gulf of Maine using the Northeast Fishery Science Center standardized bottom trawl has been problematic due to large areas of hard bottom and the proliferation of fixed fishing gear. Concerns that areas with significant fish biomass were not being sampled resulted in the NEFSC developing a summer bottom trawl survey in order to supplement sampling in this region. The NEFSC worked with regional fisherman to map areas accessible to bottom trawls and used this information to develop a sampling regime. A master list of towable areas was used to inform the stratified-random survey design which allowed sampling in these areas, while greatly reducing gear damage. This survey was conducted from 1991 through 1995.

We are evaluating how highly migratory and protected species, including cetaceans, fishes, pinnipeds, seabirds, and turtles, are using a network of state and federal marine protected areas in the Gulf of Maine and southern New England regions, and how this overlaps with areas of human use. Understanding the benefits of existing MPAs to species at risk will inform recommendations for potential new or expanded MPAs, and ensure their viability for future generations.

Data start year: 1990

Spatial scale: USA

11.11.3 Project description

The Highly Migratory Species Habitat Suitability - Past and Future layers show the model-predicted habitat suitability for a given species. These predictions are derived from species distribution models that link observations of a species to the concurrent environmental conditions the species occupied. By linking animal occurrence to the environment over large datasets, we can model how suitable a particular habitat is depending on its characteristics such as sea surface temperature and bottom depth. A higher habitat suitability indicates that location is expected to be “better” habitat for that species at that time based on ocean conditions. By leveraging the animal-environment relationships, we can use the model to project expected changes to a species’ habitat using climate model outputs that represent the future ocean. The habitat suitability product is produced on decadal timescales (using mean of monthly suitability during that decade) to provide estimates of expected climate-induced change to species habitats in the contemporary (1990s to 2010s) and future (2070s to 2090s) ocean.

The Maine-New Hampshire Inshore Trawl Survey is a fishery-independent survey operated by Maine Department of Marine Resources that started in the fall of 2000. The survey is a collaborative partnership between commercial fishermen and state researchers to assess inshore fish stocks along the coast of Maine and New Hampshire. The survey occurs twice a year, in the spring and fall, and covers about 4500 square miles.
