UK Coastal Hydrography: Backscatter and Seabed Samples from Shoreham to Selsey

New Forest District Council Civil Hydrography Programme 2016 data includes acoustic backscatter mosaics, H575 seabed samples, and images for the Shoreham to Selsey area. The data was collected by the British Geological Survey using the vessel MV Wessex Explorer with a Kongsberg EM 2040C system 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 the H575 sample data mentioned in the description.
• Map seafloor texture and roughness using the acoustic backscatter mosaics.
• Validate remote sensing models with ground-truth data from the collected seabed samples and images.

Strengths

• Data quality is supported by verification from the authoritative UK Hydrographic Office.
• Collection used a specified, modern multibeam echosounder system (Kongsberg EM 2040C).
• Dataset includes multiple complementary data types: mosaics, physical samples, and images.

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.
