Abstract
The Arctic environment is changing more rapidly than the global average, in particular declining sea ice extent and thickness and increasing freshwater runoff from the Greenland Ice Sheet. Over the past millennia, changes in the ocean-climate dynamics reshaped the Ice Sheet significantly, leaving complex landscapes beneath the seas around Greenland. The submerged post-glacial landforms serve as an archive of past ice sheet dynamics and simultaneously provide shelter to unique Arctic biodiversity from a destructive human impact on benthic environment. The hidden habitats survey carried out in southern Disko Bay in September 2019, focused on collecting novel high-resolution datasets shedding new light on the complexity of the seafloor terrain in the area, sedimentary environment and biodiversity including cold-water corals. The survey was divided into two key activities: 1) continuous geophysical survey with multi-beam SeaBat T50-ER and 2) biological sampling (stop and re-start) using underwater photo/video imaging system. Datasets from this survey are published in Krawczyk et al. (in press).
