Layers: Description: These data represent estimated commercial fishing activity from vessel monitoring system (VMS) data, for 2010 to 2022, for the United States West Coast. The analysis units are 1-minute grids (~1.8 km or 1 nm). VMS data are provided by NMFS office of Law Enforcement and compiled by PacFIN in 'Comprehensive VMS', a derived data product produced by PacFIN. Pacific States Marine Fisheries Commission (PSMFC) summarized the data using methods developed by CalPoly and BOEM (Wang, et al., in press), based on VMS Declaration Codes and estimated fishing speeds.Fishing effort is summarized using available VMS data and declaration codes reported by vessel operators.
