As part of the Department of Trade and Industry's (now Department of Energy and Climate Change) Strategic Environmental Assessment (SEA6) a geophysical survey was undertaken on SV Meridian SEA6 Survey A (or Leg 1) in the eastern Irish Sea mainly in the central region between the Isle of Man and Cumbrian coast. The aims of the data collection were to survey geographical areas where the regional BGS maps and other published data indicated knowledge gaps in the understanding of regional seabed sediment distribution patterns and processes; Create high resolution bathymetric, backscatter and superficial geological data suitable for mapping banks, deeps, transitions between seabed coarse and fine sediments and the mid-shelf and nearshore environments; Generate data suitable for calibration of previous interpretations of net bedload sediment transport directions.
Multibeam, sidescan sonar and chirp seismic data were collected.
14 gridded processed multibeam files are available. Raw data are also available.14 mosaic sidescan tif files available. Raw seismic data also available. Cruise reports are available.
