Since September 2018, six lasers from the ATLAS instrument aboard the 1.5-ton, 2.5×1.9×3.8-meter satellite have been firing at Earth from an altitude of about 490 kilometers, measuring ice sheets and sea ice thickness in the polar regions. Image: NASA...
Nasa’s video shows how sea ice expands widely starting in June, nearly doubling Antarctica’s ice-covered area before melting again. It turns out that the latter proceeds faster than sea-ice formation. Video: Nasa Looking at the development of Antarctic sea...
Antarctic sea ice is not only a motif for scenic images, but also a very dynamic pointer system for the state of Antarctica and the effects of climate change. Picture: Dr Michael Wenger The extent of sea ice is often considered an indicator of the state of the...
Many parts of the Antarctic continent can only be reached by heavy icebreakers because the sea ice around the continent forms an almost completely continuous surface. Picture: Michael Wenger In the Arctic, sea ice loss is one of the most visible effects of climate...
The dark deposits on the Greenland ice sheet are fine sediments on the one hand and signs of our modern way of life on the other. Among other things, micro- and nanoplastic particles, including tire wear and fibers from clothing, are transported by wind and water to...
