CCO CHP 2024: Bideford Bay Seabed Backscatter and Sediment Samples

Bideford Bay, UK, seabed data from the 2024 Civil Hydrography Programme, including acoustic backscatter mosaics, sediment samples, and seabed images. The data was collected by the Channel Coastal Observatory using vessels Morven and White Ribbon, 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 acoustic backscatter mosaics and physical samples.
• Map seabed morphology and features using high-resolution backscatter data.
• Validate remote acoustic sensing data with ground-truth sediment samples and images.
• Analyze sediment distribution patterns in a coastal bay using point and area shapefiles.

Strengths

• Data is verified by the authoritative UK Hydrographic Office.
• Includes multiple complementary data types: acoustic mosaics, physical samples, images, and shapefiles.
• Collection details are specified, including vessel names (Morven, White Ribbon) and multibeam echosounder model (Kongsberg EM2040C, Norbit Winghead).

Limitations

• Row count, file formats, and column-level documentation are unknown, limiting suitability assessment.
• The description lacks specific details on data resolution, sample count, or spatial extent.
• License terms are unspecified, which may restrict usage.
