In the U.S. the Coast Guard and industry collect AIS data, which can also be used for a variety of coastal management purposes. NOAA and BOEM have worked jointly to make available these data from the U.S. Coast Guards national network of AIS receivers. The original records were filtered to a one-minute frequency rate, and subset to depict the location and description of vessels broadcasting within the Exclusive Economic Zone. 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.

All data records for Alaska, including those collected by NAIS receivers, have been filtered out of our data products, at the request of the Alaska Marine Data Exchange (MXAK), who own a vast majority of the receiving stations across the state of Alaska. Conceptual Consistency These data are logically consistent Filter the raw NMEA data to a one-minute sample rate and select a subset of fields using Marine Cadastre NMEA to SQL Server processing tools Load filtered records to a SQL Server database using Marine Cadastre NMEA to SQL Server processing tools Conduct quality and completeness check using logging results from the filter and loading process, and database record counts Update the IMO, CallSign, VesselName, Length, Width, and VesselType from the AIS Vessel Identification Database (AVID) Added or updated the vessel type code field to each record fragment from AVID, if missing from AIS feed or where AVID was deemed more accurate Export records from the SQL Server database to CSV files organized by day of the year using Marine Cadastre Filter and Export utilities Modify the format of the date and time values to a UTC string format during export Modify the format of the IMO vessel number to include the "IMO" prefix during export Trim white space from string attributes during export Replaced comma punctuation marks with a semi-colon in the vessel name or call sign field if present to improve CSV formatting during export Include a header record with descriptive text for each field during export Write extracted AIS data to an ASCII CSV format file using Marine Cadastre Filter and Export utilities Compress each ASCII CSV file 2025-02-01T00:00:00 Source Contribution: Daily compressed log files containing original AIS messages in NMEA format for the months of January through December for the United States.
