Vessel AIS Locations Within U.S. Exclusive Economic Zone

Automatic Identification System data from the U.S. Coast Guard's national network, filtered to a one-minute frequency. The dataset depicts vessel locations and characteristics within the U.S. Exclusive Economic Zone, collected jointly by NOAA and BOEM for coastal management.

Use Cases

• Analyze vessel traffic density and patterns using location coordinates within the Exclusive Economic Zone.
• Model vessel movement and navigation safety by studying the one-minute frequency location broadcasts.
• Support coastal zone planning and management by correlating vessel characteristics with specific coastal areas.

Strengths

• Data originates from the authoritative U.S. Coast Guard national network of AIS receivers.
• Records are processed to a consistent one-minute frequency rate for temporal analysis.
• Spatial coverage is clearly defined as the U.S. Exclusive Economic Zone.

Limitations

• Specific data volume, row count, and column schema are unknown from the provided input.
• Primary file formats are PDF and HTML, which are not ideal for direct computational analysis without extraction.
• Data may be limited to vessels broadcasting AIS signals, excluding non-participating vessels.
