temperatures above the Weddell Sea could set off a self-amplifying meltwater feedback cycle under the Filchner-Ronne Ice Shelf, ultimately causing the second-largest ice shelf in the Antarctic to shrink [...] the researchers use an ice-ocean model created in Bremerhaven to decode the oceanographic and physical processes that could lead to an irreversible inflow of warm water under the ice shelf - a development [...] t that has already been observed in the Amundsen Sea.

Satellite observations of sea-ice thickness Two current satellite missions from the European Space Agency (ESA) provide data to measure Arctic sea-ice thickness. The thickness of seaice is a key parameter [...] parameter for many scientific and operational applications: But in contrast to the sea-ice coverage, measuring the thickness with satellites has always been challenging.
Weekly Report No 3 | 17. - 23.09.2018 Monday/Tuesday (17/18 Sep 18). A new week begins - fog, calm sea, ice free. Nothing reminds us that we are in the Arctic Ocean (but this may change soon when are steaming
Weekly Report No. 6 | 18 - 24 March 2019 Out of the heavy seaice of the Weddell Sea, we have spent the past week in open water and loose seaice in the Powell Basin. So far, we have conducted a short b
ht now, we are southeast off James Ross Island in the western Weddell Sea breaking our way to the iceberg A68 and the Larsen C ice shelf. The distance to the northern tip of A68 measures ca. 75 nautical [...] nautical miles (nm), slightly over 135 km. To our working area, the area where A 68 broke of the Larsen C ice shelf, the distance is ca. 180 nm (330 km)…

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
process with alerting consequences for modern ice sheets: continuous warming of the ocean can result in a massive loss of polar ice mass, and consequently to rapid sea level rise.
Arctic When the summer melting of the Arctic seaice ends in the middle of September, the minimum ice extent is likely to have decreased to an area of 4.4 (+/- 0.1) million square kilometres, according
