ICAROS 2021 Cruise Report. Ice-ocean interactions and marine ecosystem dynamics in Northwest Greenland

The ICAROS 2021 cruise was planned as a 3-week marine research expedition on board HDMS Lauge Koch including two complementary legs, from Aasiaat-Qaanaaq and Qaanaaq-Nuuk from 22th Aug-13th Sep. The expedition was however terminated on the 31st Aug at Pituffik (Thule Air Base) by Arctic Command due to unforeseen operational issues. This was followed by transit to Nuuk, where demobilization of equipment and disembarkment of the team took place on the 3rd Sep. This report gives an account of the research activities performed from the 22nd Aug-31st Aug, including an overview of the samples and data collected during the expedition. We note that the unexpected termination of our research activities compromises the objectives we set out to pursue.
