Goodwin Sands Marine Survey with Multibeam and Benthic Sampling

A marine environmental survey of Goodwin Sands collected multibeam bathymetry, backscatter, underwater video, and benthic grab samples. Data was gathered aboard the Cefas Endeavour in April and May 2014, with coordinates in WGS84 and depths corrected to Chart Datum. The dataset includes georeferenced mosaics and GeoTiff images.

Use Cases

• Analyze WGS84 latitude and longitude coordinates with bathymetry data to model seafloor topography.
• Process backscatter and multibeam survey data to classify benthic habitats.
• Correlate underwater video and camera stills with fauna grab samples for species identification.
• Use georeferenced mosaics and GeoTiff images for spatial analysis of marine geology.

Strengths

• Includes multiple complementary data types: multibeam bathymetry, backscatter, video, stills, and physical grab samples.
• Data is archived with authoritative UK Marine Environmental Data and Information Network (MEDIN) Data Archive Centres.
• Spatial coordinates are collected by Differential Global Positioning System (D-GPS) for accuracy.

Limitations

• Sample size for physical grabs (PSA and Fauna) is unspecified and likely limited.
• Data is from a specific 2014 campaign, potentially limiting temporal analysis of environmental changes.
• Raw data availability requires a direct request, which may delay access.
