Passively traversing the Arctic propelled solely by the natural power of the ice is the most environmentally friendly method of conduc- ting research with an icebreaker in the Arctic Ocean. The Polarstern is [...] crew members will be taking part in the major Arctic project; not least to conduct research that will allow us to better predict future changes in the Arctic sea ice and the global climate. Naturally, the [...] Journey Bremerhaven – Arctic: 19 days times 54 tonnes diesel per day: 1,026 t (travelling in water and ice) Drift: 357 days times 15 tonnes diesel per day: 5,355 t Return journey Arctic– Bremerhaven: 14 days

first aerial survey flights over the Arctic this year. The flights, which will extend far into the Central Arctic, will support the investigation of the atmosphere and sea ice, and supplement the MOSAiC [...] expedition’s extensive research agenda. Core research priorities include cloud formation over the Arctic Ocean and the question as to whether the sea ice observed during MOSAiC was generally thicker or thinner [...] Arctic
Following a five-month mandatory delay due to the coronavirus pandemic, on August 30th the two German polar research aircraft Polar 5 and Polar 6 will launch from Svalbard to conduct their first

refreezing at the sea ice surface dramatically changes the energy exchange between atmosphere and ocean in the Arctic. Melt ponds play a key role in these changes, because they substantially enhance the absorption [...] albedo of Arctic summer ice from satellite optical data.
