Name: 2012 Tanker Vessel Density

Display Field:

Type: Raster Layer

Geometry Type: null

Description: This layer shows the density of vessel traffic in 2012 for tanker 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.
