The aim is to re-visit the Darwin Mounds and NW Rockall Bank MPAs and assess their status and the status of the cold-water corals, to test a new stereocamera system for the Autosub6000 AUV(BIOCAM) and to collect water column profiles on the Rockall margin. For iAtlantic we will collect additional box cores for macrofauna study (timeseries). Gear: AUV, HyBIS video platform, boxcore, megacore, CTD, mooring deployments.
