Marine Benthic Survey with Multibeam and Video Data from Northern North Sea

A groundtruthing survey collected Hamon grab samples for infaunal analysis and Particle Size Analysis (PSA), alongside video and still image data. The dataset includes multibeam bathymetry and backscatter, with WGS84 coordinates from Differential GPS and depths corrected to Chart Datum. Data was processed and archived by the British Geological Survey and other UK Marine Data Archive Centres.

Use Cases

• Classify benthic habitats using video and still image data combined with grab sample infaunal analysis.
• Analyze seabed composition by correlating multibeam backscatter data with Particle Size Analysis (PSA) from grab samples.
• Model bathymetry and depth corrections to Chart Datum using the collected multibeam and GPS coordinate data.
• Train computer vision models on underwater video and image data to identify marine species and substrates.

Strengths

• Includes multiple complementary data types: physical grab samples, video, images, bathymetry, and backscatter.
• Data is geospatially precise, using WGS84 coordinates collected by Differential GPS.
• Archived and validated by authoritative UK Marine Environmental Data and Information Network (MEDIN) Data Archive Centres.

Limitations

• Sample size and temporal scope are limited to a single survey from April 30 to May 5, 2012.
• The dataset's geographic coverage is restricted to the specific Markham's Triangle area in the Northern North Sea.
• Access to the full raw data package may require a direct request to the British Geological Survey.
