    • 2011 Tug Towing Vessel Density

    Metadata Updated: March 15, 2024

    Automatic Identification Systems (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. This dataset represents the density of tug and towing vessel traffic in 2011 for the contiguous United States offshore waters from tug or towing vessels with AIS transponders in 100 meter grid cells. The dataset is best interpreted using a high to low density scale and does not represent actual vessel counts.
