Notice: Some maps on Northeast Ocean Data may be unavailable from 7:00 a.m. to 12:00 p.m. on Sunday, January 19, due to routine maintenance on NOAA's map services.  

In June 2019, the Northeast Data Portal, in coordination with the Marine-life Data and Analysis Team (MDAT), the NOAA Northeast Fisheries Science Center (NEFSC)OceanAdapt, and the Mid-Atlantic Ocean Data Portal, released updated maps depicting the distribution and biomass of fish species in the northeastern U.S. continental shelf ecosystem.

A new tutorial demonstrates how to access the updated data products and displays some of the new and updated features in the updated maps, including:

  • Layers showing average species biomass over approximately the most recent decade
  • Addition of spring trawl results and how to compare biomass between fall and spring
  • Ability to view federal trawl results with various state and coastal trawl results
  • How to overlay fish biomass data with other data layers in the Data Explorer

View the tutorial by clicking on the video player above, or watch it at https://vimeo.com/368104910.

See the June 2019 announcement for more information about the updated federal trawl data products.
