Purpose
Abstract MSM55 targeted on two contrasting sites of intense biogenic carbonate production in the coastal waters of the arctic Svalbard Archipelago. These are the rhodolith beds in Mosselbukta in the far North of the archipelagoss main island Spitsbergen, and the extensive biogenic carbonate sediments accumulating in the strong hydrodynamic regime of the Spitsbergen- and Bjoney-Banken in the South. The beam spacing of the EM122 was set to equidistant. The survey speed varied between ca. 4.5 kts (when a sidescan-sonar fish was towed simultaneously) and 10 kts.
