Maritime and Coastguard Agency (MCA) Civil Hydrography Programme 2022 Backscatter and Samp

UK coastal data from the Ballacash Channel, collected by the Maritime and Coastguard Agency's Civil Hydrography Programme in 2022. The dataset includes acoustic backscatter mosaics and H575 seabed samples, verified by the UK Hydrographic Office. Data was gathered using vessels FPV Morven and Cerys Line System with an EM 2040C system.

Use Cases

• Classifying seabed sediment types based on acoustic backscatter data.
• Mapping seafloor morphology and roughness from backscatter mosaics.
• Ground-truthing remote sensing data using physical H575 seabed samples.
• Analyzing channel bathymetry and substrate for nautical charting.

Strengths

• Data is verified by the authoritative UK Hydrographic Office.
• Includes both acoustic (backscatter mosaics) and physical (H575 samples) data types.
• Collection methodology is specified, using vessels FPV Morven and Cerys Line System with an EM 2040C system.

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.
