2019 AIS vessel data summarized by BOEM aliquot (1200x1200m polygons) for the West Coast.
Data is available as All Ships, and by vessel type for Tankers, Cargo Ships, Tugs & Tows, and Fishing Vessels.
Because Vessels smaller than 300 gross tones (~65 ft) are not required to have AIS, smaller fishing vessels are not well represented by the fishing dataset.
