KIT’s “Atlas of Antarctic Sea Ice Motion” now added to the data and information portal meereisportal.de
5 March 2021
Continuous datasets from the polar regions are valuable witnesses of the climate change that has become increasingly apparent around the globe since the 1980s. These include data on sea-ice formation and dynamics in the Antarctic pack-ice belt. When the Federal Republic of Germany became a signing member of the Antarctic Treaty in 1979 and established the Georg-von-Neumayer Station, an Antarctic station operated year-round, the stage was set for gathering regular readings in this normally hard-to-access region. In this context the “Atlas of Antarctic Sea Ice Motion” was developed. The KIT’s Atlas of Antarctic Sea Ice Motion was subsequently prepared for its new role as a permanent resource available at the AWI’s meereisportal.de, which will also make it possible to combine it with other datasets from after 1998 in the future.

Sea-ice Development in Both Polar Regions Largely Normal
15 February 2021
Following 2020, a year that managed to break a number of records in the Arctic, the new year has begun less spectacularly, as a closer examination of the months December and January shows. The current winter season in the Arctic is particularly influenced by the temperature anomaly, which in December produced temperatures up to 5°C above the long-term average for 1971 to 2000 in the Laptev Sea and Central Arctic, and over East Greenland and Northern Canada. The atmospheric circulation linked to this temperature pattern in January was dominated by high pressure over Siberia and low pressure over the northern North Atlantic and North Pacific.

DriftStories from the Central Arctic – one year, one floe – sea-ice research to the extreme!
20. Januar 2021
Never before have experts had the chance to investigate the Arctic sea ice as comprehensively as on the international expedition MOSAiC, on board the research icebreaker Polarstern. For an entire year, the ship drifted with the ice through the Central Arctic; for an entire year, the men and women of MOSAiC used cutting-edge technologies to study every facet of the ice around them.
They share the challenges they had to overcome, and what they learned at the polar hotspot of climate change, in the following ten DriftStories, which have now also been collected in the booklet “DriftStories from the Central Arctic”.
