MCA CHP 2025: Seafloor Backscatter and Sample Data for Bahama Bank South

Acoustic backscatter mosaics, seabed sample records, and sample images collected for the Bahama Bank South area. The data was gathered by the vessel Northern Gale as part of the UK's Civil Hydrography Programme and verified by the UK Hydrographic Office. The dataset was published by the British Geological Survey and last updated in April 2026.

Use Cases

• Classify seafloor sediment types based on acoustic backscatter mosaics
• Map natural seabed features based on provided shapefiles
• Validate remote sensing data with physical seabed sample records and images

Strengths

• Data verified by the authoritative UK Hydrographic Office
• Includes multiple complementary data types: mosaics, sample records, images, and shapefiles

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
