Multibeam Bathymetry and Seabed Imagery for Cromer Shoal Chalk Beds

A marine survey dataset from the Southern North Sea conducted from January 28 to 30, 2013. It includes partial coverage multibeam data for bathymetry and backscatter, along with drop camera video and still images of seabed habitats. The data is archived with multiple UK Marine Environmental Data and Information Network (MEDIN) Data Archive Centres.

Use Cases

• Analyze seabed habitat types using georeferenced video and still image mosaics from the drop camera survey.
• Map bathymetric features and backscatter intensity from multibeam data with WGS84 latitude and longitude coordinates.
• Model seafloor geology by integrating corrected depth data to Chart Datum with geophysical survey information.
• Assess marine protected area conditions within the Cromer Shoal Chalk Bed rMCZ using combined imagery and bathymetry.

Strengths

• Data includes multiple sensor types: multibeam for bathymetry/backscatter and drop cameras for video/still imagery.
• Geographic coordinates are collected by Differential Global Positioning System (D-GPS) and corrected to Chart Datum.
• Archived with authoritative UK Marine Environmental Data and Information Network (MEDIN) Data Archive Centres.

Limitations

• Multibeam survey coverage is described as partial, indicating incomplete spatial mapping of the area.
• Dataset represents a short temporal snapshot from a three-day survey in January 2013.
• Raw data availability requires a direct request, suggesting immediate access may be limited to processed formats.
