By mid-September it covered only 3.8 million [...] formed in Russia’s marginal seas, and soon melted again when the spring came. Secondly, this year the Arctic has seen extremely high air and water temperatures. Accordingly, heat gnawed away at the ice from
Sea Ice The Arctic sea ice continues to dwindle: Since the 1970s, when satellites first began monitoring the white sheet covering the ArcticOcean, its February extent was never as small as it was this [...] this year. The reason: warm air intrusions, which are not only hitting the Arctic more frequently, but are also intensifying and reaching farther north.
have now shown, the ocean may weaken warming around Antarctica and delay sea-ice retreat. Given that many models are not capable of accurately reflecting this factor and the role of ocean eddies, the study [...] Climate Research Despite global warming and the sea-ice loss in the Arctic, the Antarctic sea-ice extent has remained largely unchanged since 1979. However, existing climate model-based simulations
Arctic Sea Ice The sea-ice extent in the Arctic is nearing its annual minimum at the end of the melt season in September. Only circa 3.9 million square kilometres of the ArcticOcean are covered by
br>How do you successfully pilot a remote-controlled helicopter in the remote expanses of the ArcticOcean when the compass can’t provide reliable positioning data? Engineers on board the Alfred Wegener
Research aircraft from the Alfred Wegener Institute have been surveying the ice-covered ArcticOcean for 30 years. The immense effort of the past 52 expeditions has paid off: 40,000 km of measurement data [...] aeroplane- and helicopter-based measurement series in the world that has been carried out in the Arctic over such a long period. Currently, two Basler BT-67 aircraft are in operation: the Polar 5 and Polar

It is exceeded only by the all-time [...] all-time record low of 3.4 million sq km in 2012. "Once again, a massive loss of sea ice in the Arctic," says Prof. Lars Kaleschke from Universität Hamburg's Center for Earth System Research and Sustainability

Arctic cod is the most abundant fish in the ArcticOcean. It is an important food source for Arctic marine mammals and plays an important role in the self-sufficiency of the Inuit. An international study [...] now evaluated the most important scientific work on Arctic cod of the past decades.
