• Oceanic microseisms

    layers of the ground, oceanic microseisms can spread over many hundreds of kilometres. 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. The red stars mark the oceanic microseisms research projects. (Graphic: Alfred-Wegener-Institut) Contact

  • On thin ice in the warm Arctic

    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.

  • Open waters around the North Pole: Arctic sea ice in retreat

    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
