Marine Bathymetry Survey of Greater Haig Fras in Celtic Sea

A multibeam survey collected bathymetry and backscatter data for the Greater Haig Fras Marine Conservation Zone. The survey was conducted from February to March 2014, meeting International Hydrographic Organization Order 1a standards. Data includes georeferenced mosaics and GeoTiff images archived with UK Marine Environmental Data and Information Network centers.

Use Cases

• Analyze bathymetry data to model seafloor topography and identify underwater features in the survey area.
• Process backscatter data to classify seabed sediment types and habitat characteristics.
• Integrate georeferenced mosaics and GeoTiff images with other marine geospatial datasets for habitat mapping.
• Assess survey coverage gaps caused by poor weather conditions for planning future data collection campaigns.

Strengths

• Data collected to International Hydrographic Organization Order 1a standard, a recognized hydrographic specification.
• Includes both raw and processed data deliverables, such as georeferenced mosaics and GeoTiff images.
• Archived with multiple UK Marine Environmental Data and Information Network Data Archive Centres for long-term preservation.

Limitations

• Survey achieved only partial seafloor coverage due to poor weather conditions during the collection period.
• Specific technical details on data resolution, point density, or file sizes are not provided in the description.
