sea ice in the Arctic has several key functions in the Earth's climate system: it reflects large parts of the solar radiation, thus slowing down global warming and it drives global ocean and air currents [...] outside our window. How the sea ice retreats or expands depends largely on the energy balance of the Arctic Ocean surface. However, there is a lack of data from direct observations, meaning that studies have [...] AI-supported model that can correct these biases and thus contribute to a better understanding of Arctic climate processes. They present their method in the scientific journal Geophysical Research Letters

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

These waters, also known as the Arctic Ocean, extend to the northern coasts of Scandinavia, Russia, North America and Greenland. They lie completely within the Arctic Circle and are [...] Pole, the Arctic magnetic pole and the Arctic geomagnetic pole. Measuring 4,000 kilometres long, 2,400 kilometres wide and covering an area of roughly 14 million square kilometres, the Arctic Ocean is the

Seismology in (sub)polar oceans Contact Prof. Dr. Vera Schlindwein Seismology in stormy oceans In the stormy „Furious Fifties“ we succeeded for the first time to recover ocean bottom seismometers after [...] when the ice cover is almost 100% (Expedition PS137 of RV Polarstern). The data show that the Arctic Ocean offers good recording conditions for earthquakes due to the unprecedentedly low seismic noise [...] originating at the Southwest Indian Ridge now provide unprecedented insight into the formation of new ocean lithosphere.

The Arctic is not spared from this trend [...] However, due to local processes and conditions, marine heatwaves in the Arctic differ fundamentally from those in non-polar oceans.

Sea Ice
The Arctic sea ice continues to dwindle: Since the 1970s, when satellites first began monitoring the white sheet covering the Arctic Ocean, 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.

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 Arctic Ocean are covered by
