The Marine Life Library is home to thousands of maps depicting populations of individual species of fish, birds and marine mammals along the East Coast. The maps were created by the Marine-life Data and Analysis Team (MDAT) and Northeast Data Portal in coordination with the NOAA Northeast Fisheries Science Center (NEFSC), OceanAdapt, and Mid-Atlantic Ocean Data Portal, and cover the Northeast U.S. Shelf ecosystem from Maine to Cape Hatteras. Users should visit http://seamap.env.duke.edu/models/mdat/ for a report with a full explanation of this data. The site also includes downloadable map data products, metadata and other information related to the MDAT project.
