Processing and interpretation of water column data from the Polarrev High, Barents Sea
This study was carried out using multibeam echo sounder data collected during Mareano surveys in 2013. The data from the surveys have been processed and interpreted to identify natural gas seeps, visible as gas flares, in the water column data. The data is also used for extracting bathymetry and backscatter. The study area lies on the Bjarmeland platform area in the southern Barents Sea, mainly over the Polarrev High with a small part lying in the Kong Karl Platform and Bjarmeland Platform. The water depth is shallow and ranges from 150 to 225 m.
