MCA CHP 2025: Seabed Backscatter and Sample Data for Southeast Northern Ireland

2025 data from the UK's Civil Hydrography Programme includes acoustic backscatter mosaics, seabed sample records, sample images, and natural feature shapefiles for the Southeast Northern Ireland A area. The data was collected by the vessel Northern Gale 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

• Create seabed classification maps based on acoustic backscatter mosaics.
• Analyze seabed sediment composition based on H575 sample records and images.
• Map natural seabed features like reefs or sandwaves based on provided shapefiles.

Strengths

• Data is verified by the authoritative UK Hydrographic Office.
• Includes multiple complementary data types: mosaics, sample records, images, and shapefiles.
• Specific collection vessel (Northern Gale) and programme (Civil Hydrography Programme) are documented.

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.
• Data may reflect geographic bias inherent to the specific survey area.
