U.S. Vessel AIS Data Filtered to One-Minute Frequency

Automatic Identification System (AIS) data from the U.S. Coast Guard's national receiver network, processed by NOAA and BOEM. The original records were filtered to a one-minute frequency and subset to vessel broadcasts within the U.S. Exclusive Economic Zone. This data supports navigation safety and coastal management purposes.

Use Cases

• Model maritime traffic patterns based on real-time vessel location broadcasts.
• Assess coastal environmental impact based on vessel activity within the Exclusive Economic Zone.
• Enhance navigation safety analytics based on AIS-transmitted vessel characteristics.
• Support port and infrastructure planning based on vessel density and movement data.

Strengths

• Data is sourced from the authoritative U.S. Coast Guard national AIS network.
• Records are processed to a standardized one-minute frequency for temporal consistency.
• Spatial coverage is defined as the U.S. Exclusive Economic Zone.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Available file formats are PDF and HTML, which may not be optimal for direct analysis.
