DEFRA MCZ: Mid St Georges Channel Multibeam Bathymetry Survey, March 2012

Full coverage multibeam survey data collected to International Hydrographic Organization Order 1a standard between March 17 and 30, 2012. The dataset includes bathymetry, backscatter, and processed georeferenced mosaics delivered to the Centre for Environment, Fisheries and Aquaculture Science. These data are archived with the Marine Environmental Data and Information Network and the British Geological Survey.

Use Cases

• Modeling seabed bathymetry based on multibeam survey data
• Analyzing seabed composition and texture based on backscatter data
• Creating habitat maps based on georeferenced mosaics and GeoTiffs
• Conducting marine spatial planning based on high-resolution survey data for the Mid St Georges Channel

Strengths

• Data collected to International Hydrographic Organization Order 1a standard, indicating high positional and depth accuracy
• Includes both raw and processed data, along with georeferenced mosaics and GeoTiff images
• Archived with multiple Marine Environmental Data and Information Network Data Archive Centres, ensuring long-term preservation

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the specific survey area in the Irish Sea
