Seafloor sediments reveal how East Antarctic ice temporarily halted its retreat and advanced 40 miles
Off the coast of East Antarctica, researchers led by Kiel University (CAU) and the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have investigated an exceptionally large sedimentary body embedded in the seafloor of Vincennes Bay: a so-called "grounding-zone wedge"—symmetrical, wedge-shaped, approximately 260 meters (853 feet) high and 65 kilometers (40 miles) long. With a volume of more than 580 cubic kilometers (139 cubic miles), it is the largest known isolated grounding-zone wedge on a glaciated continental shelf to date and constitutes an exceptional archive of East Antarctica's glacial history.
In Eastern Antarctica there is an enormous accumulation of sediments under the sea that preserves the traces of a key episode in the history of its ice sheet
A huge hill under water could help explain why Antarctica's ice does not retreat immediately everywhere. Researchers from Kiel show what role the seabed plays in this.
Kiel researchers have discovered a "Bremsklotze" for the ice melt in Antarctica. What this means for future forecasts.
