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. In the U.S. the Coast Guard and industry collect AIS data, which can also be used for a variety of coastal planning purposes. NOAA and BOEM have worked jointly to re-task and make available some of the most important records from the U.S. Coast Guard's national network of AIS receivers. This dataset represents annual vessel transit counts summarized at a 100 m by 100 m geographic area. A single transit is counted each time a vessel track passes through, starts, or stops within a 100 m grid cell. This record represents the metadata for each of these vessel types: Cargo, Fishing, Passenger, Pleasure Craft and Sailing, Tanker, and Tug and Towing. To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.

Horizontal Positional Accuracy Maximum scale of intended use is 1:80,000. Positional accuracy reflects the specifications and methods of the original data producer and has not been modified for the generation of this product. Completeness Report All known records acquired from the Nationwide Automatic Identification System which includes approximately 58 U.S. ports and 11 coastal areas out to 24 nautical miles offshore. For further information on vessel reporting requirements and participation in the AIS, see carriage requirements in the Code of Federal Regulations, Title 33. Significant null values exist in some fields principally as a result of vessel operator practices. Conceptual Consistency Tested through visual inspection and through the analysis of summary statistics on field values. 1. Select tracks for each vessel type from the 2015 AIS Vessel Tracks geodatabase by groups as defined in the AIS Vessel Type and Group Codes, Marine Cadastre 2018-05-23. 2. Calculate transit count grids using the MarineCadastre.gov AIS Vessel Transit Counter tool for each month of tracks and for each ocean basin. 3. Merge monthly transit count grids into an annual transit count grid. 2018-01-02T00:00:00 1.
