The expedition Arctic Ocean 2018 with the icebreaker I/B Oden was conducted by the Swedish Polar Research Secretariat in collaboration with National Science Foundation. The main theme for the research was the “Life cycle of clouds in the high Arctic summer with linkages to the microbial life in ocean and iceâ€.To obtain the best circumstances, I/BO den sailed into the High Arctic where the ship, logistics and scientific staff scouted for asuitable ice floe to sample from. I/B Oden was moored to this floe for approx. 5 weeks in mid-August 2018 such that the scientific work could cover the minimum ice extent period and, most importantly, the refreezing processes. Arctic Ocean 2018 used 5 work packages (WP) to achieve the stated aims of understanding the controlling factors of the proposed negative feedback involving micro-organism and clouds over the Arctic pack ice area. This 5 WP grouping reflects the outcome of the 2 science workshops held prior to the expedition and agreed upon by the participating scientists at the time. WP1: Meteorology and vertical profiling WP2: In-situ characterization of ambient gases, aerosols and clouds WP3: Air-sea interaction WP4: Sea surface microlayer composition WP5: Physics, microbiology and biogeochemistry of ocean water and ice.
