    • VMS Dungeness Crab 2010-2017 (BOEM)

    Metadata Updated: January 25, 2026

    2010-2017 Vessel Monitoring System (VMS) data were used from the NOAA Office of Law Enforcement to create this fishing effort dataset for the U.S. West Coast. The dataset was generated using VMS points at fishing speeds to create fishing tracks. Tracks were joined to the BOEM aliquot grid (1.2x1.2 km) to create heat maps of fishing effort for various fisheries based on individual and combined declaration codes.
