MCA CHP 2025: Seafloor Backscatter and Samples from Dover Strait

Acoustic backscatter mosaics and seabed samples from the Civil Hydrography Programme's 2025 survey northeast of Le Colbart in the Dover Strait. The British Geological Survey collected this data, which was subsequently verified by the UK Hydrographic Office. It includes seabed imagery and natural feature shapefiles.

Use Cases

• Map seafloor sediment types based on acoustic backscatter mosaics.
• Identify and classify seabed natural features based on provided shapefiles.
• Analyze seabed composition and texture based on collected H575 samples and images.

Strengths

• Data quality is verified by the authoritative UK Hydrographic Office.
• Includes multiple complementary data types: mosaics, samples, images, and shapefiles.

Limitations

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