considerable gap in monitoring ice loss in the Antarctic and Greenland. Now the follow-up mission will finally be launched, and will play a vital role in predicting future sea level rise. [...] Sea Level Rise A few months ago, the GRACE mission’s two Earth observation satellites burnt up in the atmosphere. Although this loss was planned, for the experts at the Alfred Wegener Institute it left
Arctic, where the onset of summer also marks the beginning of the annual sea-ice melting. Over the past 40 years, the summer sea-ice extent has decreased by 40 percent – making it one of the most visible [...] conducted in the marginal ice zone, the team of researchers on board will investigate how heat fluxes and water layering in the ocean, as well as the characteristics of the ice, interact and influence melting
to a significantly increased melting rate of the Filchner Ronne Antarctic ice shelf, resulting in a substantial rise in global sea levels. [...] to result in significantly increased deep water temperatures in the Filchner Trough in the Weddell Sea in Antarctica, reports a modelling study lead by researchers of the Alfred Wegener Institute and published
whale populations in the Weddell Sea, both of which avoid the seaice and call or sing most frequently in the autumn. In contrast, Antarctic minke whales primarily live in ice-covered regions and produce their [...] for the past nine years, to successfully gather and analyse whale observation data from the Weddell Sea. The audio recordings offer unique insights into the lives of humpback whales and Antarctic minke whales
Arctic was completely ice-free during summer and sea-surface temperature reached values of 4 to 9 degrees Celsius. In spring, autumn and winter, however, the ocean was covered by seaice of variable extent
glacial periods, the sea level falls, because vast quantities of water are stored in the massive inland glaciers. To date, however, computer models have been unable to reconcile sea-level height with the

The North East Greenland Ice Stream transports enormous amounts of ice from the heart of the island to the sea and thus also influences global sea levels. An international research team led by the Alfred [...] of Greenland around 2,000 years ago. The study, which opens up new possibilities for research into ice sheets, was recently published in the scientific journal Nature Communications .
Polarstern expedition jointly decided to abandon their efforts to reach the Larsen C Ice Shelf. Since dense seaice and ice ridges blocked the planned route, the ship has now set course for alternative research
journal Frontiers in Ecology and the Environment , indicate that sea-ice retreat has had significant effects on the animals’ behaviour: when the ice disappears, areas normally full of vocalisations become very
