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

It is now well researched how strong storms not only generate large waves, but also increased oceanic microseisms activity [...] other way round: what does oceanic microseisms tell us about the nature of the ice over the course of the seasons? To answer these questions, we use data from our ice-going ocean-bottom seismometers (OBS) [...] microseismics were also recorded, which we are currently analysing. Map of the Arctic and Antarctic.

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.

Arctic Ocean
This September, the Arctic sea ice extent has shrunk to 4.1 million square kilometres (sq km)-the second lowest in the history of satellite measurements. 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
