Description: This layer shows the density of vessel traffic in 2011 for all vessels that carry Automatic Identification System (AIS) transponders. AIS are a navigation safety device that transmits and monitors the location and characteristics of many vessels in U.S. and international waters in real-time. The data represent density in 100 meter grid cells and are best interpreted using a high to low density scale.

The data represent vessel transit counts in 100 meter grid cells. A single transit is counted each time a vessel track passes through, starts, or stops within each grid cell.
