66901 Data Set Published / External 66799 NOAA Distribution Mapping and Analysis Portal (DisMAP) Project On Going 2022-03-07 2022-03-07 These files contain the key distribution metrics of center of gravity, range limits, and depth for each species in the portal. This data set covers 7 regions of the United States: Northeast, Southeast, Gulf of Mexico, West Coast, Eastern Bering Sea, Aleutian Islands, and Gulf of Alaska. These data were created as part of the DisMAP project to enable visualization and analysis of changes in fish and invertebrate distributions. This table provides the key metrics used to evaluate a species distribution shift. Information on species distributions is of paramount importance for understanding and preparing for climate-change impacts, and plays a key role in climate-ready fisheries management.

During this processing step, decisions where made to in some cases trim a regions data to either eliminate certain years or strata based on evaluation of survey coverage for those years or strata. 2022-03-07T00:00:00 Organization NMFS Office of Science and Technology OST https://ror.org/04950b532 1315 East West Highway Silver Spring MD 20910 USA 301-427-8100 https://www.fisheries.noaa.gov/about/office-science-and-technology NOAA Fisheries Office of Science and Technology Online Resource 0700 - 1800 EST/EDT 3 The processed data was then fed into a Python script to generate the interpolated biomass distribution maps.
