MCA CHP 2023: Dogger Bight North Seabed Backscatter and Sample Data

Maritime and Coastguard Agency Civil Hydrography Programme 2023 data for the Dogger Bight North area. The dataset includes acoustic backscatter mosaics, H575 seabed samples, and images, collected by the vessels Noortruck and Mintaka using a Kongsberg EM 2040 system. Data and records were verified by the UK Hydrographic Office.

Use Cases

• Map seabed hardness and texture based on acoustic backscatter mosaics.
• Analyze sediment composition based on H575 seabed samples.
• Classify seabed habitats based on combined backscatter and sample imagery.

Strengths

• Data verified by the authoritative UK Hydrographic Office.
• Includes multiple complementary data types: mosaics, samples, and images.
• Collection methodology specified: Kongsberg EM 2040 system used on named vessels.

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.
