MCA CHP 2024: Kentish Knock Seabed Backscatter and Sediment Samples

Maritime and Coastguard Agency Civil Hydrography Programme 2024 data for the Kentish Knock area includes acoustic backscatter mosaics, seabed samples, and sediment shapefiles. The data was collected by vessels Northern Wind and Lode using a Kongsberg EM 2040D system and verified by the UK Hydrographic Office. The dataset is provided by the British Geological Survey and was last updated in April 2026.

Use Cases

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

Strengths

• Data is verified by the authoritative UK Hydrographic Office.
• Includes multiple complementary data types: mosaics, samples, images, and shapefiles.
• Collection methodology is specified, involving vessels Northern Wind and Lode with a Kongsberg EM 2040D system.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count, file formats, and license are unknown, which may limit suitability assessment.
