AIS Vessel Tracking Records for Ocean Noise Study, 2018-2020

AIS vessel tracking records were used in a study of low-frequency ocean noise off the California coast. Data span January through July of 2018, 2019, and 2020. The data file was authored by John Ryan and is listed as Open Access.

Use Cases

• Correlate vessel traffic patterns with low-frequency ocean noise levels based on the study context.
• Analyze seasonal and interannual trends in maritime activity off the California coast based on the three-year time range.
• Model vessel movements and density for environmental impact assessments based on the geospatial tracking data.

Strengths

• Data covers a multi-year period spanning 2018 to 2020.
• Records are geolocated to a specific study region off the California coast.
• The dataset is associated with a specific research study on ocean noise.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
