MCA CHP 2023: Dogger Bank Seabed Backscatter and Sediment Samples

Acoustic backscatter mosaics, seabed samples, and sediment shapefiles collected for the UK Civil Hydrography Programme. Data was gathered by the vessel Minataka I using a Kongsberg EM 2040 system and verified by the UK Hydrographic Office. The dataset focuses on the Dogger Bank North Central West area.

Use Cases

• Classify seabed sediment types based on the sediment point and area shapefiles.
• Analyze seabed texture and roughness using the acoustic backscatter mosaics.
• Ground-truth remote sensing data with the physical H575 seabed samples and images.

Strengths

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

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.
• Data may reflect geographic bias inherent to the specific Dogger Bank survey area.
