Description: Vessel traffic information was compiled from the U.S. Coast Guard (USCG) Automatic Identification System (AIS) for the year 2014. Intensity of vessel traffic was calculated from raw AIS data and transformed using a custom-built R script to measure sum length (m) of ship tracks within 100 m pixels. Line segments with an elapsed time greater than 1 hour or average speed greater than 50 km were not included. The AIS data were log transformed and rescaled between 0 and 1.
