MCA CHP 2022: Acoustic Backscatter and Seabed Samples from Ballacash Channel

Maritime and Coastguard Agency Civil Hydrography Programme 2022 data for the HI1758 Ballacash Channel NE area includes acoustic backscatter mosaics, H575 seabed samples, and images. The data was collected by the UK Hydrographic Office vessel FPV Morven using 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 acoustic backscatter mosaics.
• Validate acoustic data interpretations using physical H575 seabed samples.
• Map seafloor features and habitats using combined backscatter and image data.
• Model sediment transport and erosion in the Ballacash Channel area.

Strengths

• Data is verified by the authoritative UK Hydrographic Office.
• Includes multiple complementary data types: mosaics, physical samples, and images.
• Specifies the collection vessel (FPV Morven) and sensor (Kongsberg EM 2040C).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
