Multibeam Bathymetry Survey of South Celtic Deep Marine Zone

British Geological Survey archives a multibeam survey for the South Celtic Deep Marine Conservation Zone. Data includes bathymetry and backscatter collected to International Hydrographic Organization Order 1a standards from February to March 2013. Processed deliverables contain georeferenced mosaics and GeoTiff images.

Use Cases

• Generate high-resolution bathymetric charts from corrected depth data for nautical navigation.
• Analyze seafloor composition and texture using backscatter intensity values.
• Model seabed topography for habitat mapping using georeferenced mosaic layers.
• Conduct change detection in the Western Channel by comparing this survey's latitude and longitude coordinates with newer datasets.

Strengths

• Data adheres to International Hydrographic Organization Order 1a survey standards.
• Survey includes crosslines run at approximately 20 times the spacing of main lines for quality control.
• Full site data package with raw and processed data is archived with multiple Marine Environmental Data and Information Network Data Archive Centres.

Limitations

• Dataset size, row count, and specific column structure are unknown from the provided metadata.
• Data is from a single survey in 2013 and may not reflect current seabed conditions.
• Access to the full raw data package may require a direct request from the British Geological Survey.
