Description
A 2013 survey collected multibeam bathymetry, backscatter, video, still images, and sediment samples from the East of Haig Fras region. The dataset includes approximately 50 sediment grab stations and camera surveys at one in every three target stations. Data is archived with UK Marine Environmental Data and Information Network centers.
Use Cases
Analyze bathymetry and backscatter data to map seafloor morphology and sediment types.
Classify predicted sediment and habitats using the collected video and stills images.
Study infauna community composition from the 50 mini Hamon grab sediment samples.
Integrate georeferenced mosaics and GeoTiffs for spatial analysis of marine protected areas.
Strengths
Data collected to International Hydrographic Organization Order 1a standard for bathymetry.
Includes multiple data types: multibeam, imagery, and physical sediment samples from 50 stations.
Archived with authoritative UK Marine Environmental Data and Information Network Data Archive Centres.
Limitations
Limited temporal scope from a single survey conducted over four days in February 2013.
Sample size is constrained to 50 grab stations and a subset of camera survey stations.
Raw data availability may require a direct request from the British Geological Survey.
