HI1818 Bahama Bank North: Seabed Backscatter Mosaics and Sample Data

Maritime and Coastguard Agency Civil Hydrography Programme 2025 data for the Bahama Bank North area includes acoustic backscatter mosaics, seabed samples, and natural feature shapefiles. The data was collected by the MV Northern Wind using a Kongsberg EM 2040D multibeam echosounder and verified by the UK Hydrographic Office. The dataset was last updated on the platform in April 2026.

Use Cases

• Classify seabed sediment types based on acoustic backscatter mosaics.
• Map the distribution of natural seabed features using provided shapefiles.
• Validate remote sensing data with physical seabed samples and images.

Strengths

• Data is verified by the authoritative UK Hydrographic Office.
• Includes multiple complementary data types: mosaics, physical samples, and shapefiles.
• Collection details are specified, including the vessel and sensor (Kongsberg EM 2040D).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file sizes are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific survey area.
