MCA CHP 2024: Seafloor Backscatter and Sediment Data for Race Bank to Sheringham Shoal

UK seabed data from the Race Bank to Sheringham Shoal area, collected in 2024. The dataset includes acoustic backscatter mosaics, seabed sample images, and sediment shapefiles, verified by the UK Hydrographic Office. It was gathered by the British Geological Survey using the vessel MV Northern Wind and a Kongsberg EM 2040D multibeam echosounder.

Use Cases

• Classify seabed sediment types based on acoustic backscatter mosaics.
• Map sediment distribution patterns based on point and area shapefiles.
• Analyze seabed texture and composition based on sample images and sediment data.

Strengths

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

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.
