Warm, moist rivers of air in Antarctica play a key role in creating massive holes in sea ice in the Weddell Sea and may influence ocean conditions around the vast continent as well as climate change, according to Rutgers co-authored research. Scientists studied the role of long, intense plumes of warm, moist air – known as atmospheric rivers – in creating enormous openings in sea ice. They focused on the Weddell Sea region of the Southern Ocean near Antarctica, where these sea ice holes (called polynyas) infrequently develop during the winter.
The German icebreaker Polarstern returned home after being frozen near the top of the world as part of the Multidisciplinary Drifting Observatory for the Study of Arctic Climate, or MOSAiC program, to study all aspects of the Arctic system.
A study of 40 sea ice models finds they all project that the area of sea ice around Antarctica will decrease by 2100, but the amount of loss varies between the emissions scenarios.
The movement of sea ice between Arctic countries is expected to significantly increase this century, raising the risk of more widely transporting pollutants like microplastics and oil, according to new research from CU Boulder.
The prevailing view has been that more leads are associated with more low-level clouds during winter. But University of Utah atmospheric scientists noticed something strange in their study of these leads: when lead occurrence was greater, there were fewer, not more clouds.
The Arctic region is heating up faster than any other place on Earth, and as more and more sea ice is lost every year, we are already feeling the impacts. IIASA researchers explored strategies for cooling down the oceans in a world without this important cooling mechanism.
Emperor penguins are some of the most striking and charismatic animals on Earth, but a new study from the Woods Hole Oceanographic Institution (WHOI) has found that a warming climate may render them extinct by the end of this century. The study, which was part of an international collaboration between scientists, published Nov. 7, 2019, in the journal Global Change Biology.
A University of Washington team is leaving to study how fall storms, dwindling sea ice and vulnerable coastlines might combine in a changing Arctic.
Meltwater ponds riddle a kilometer-thick ice shelf, which then shatters in just weeks, shocking scientists and speeding the flow of the glacier behind it into the ocean to drive up sea level. A new study puts damage by meltwater ponds to ice shelves and sea level into cool, mathematical perspective.
The German icebreaker RV Polarstern is scheduled to set sail today from Tromsø, Norway, for a 13-month journey to wherever the sea ice takes it. In a week or so, the ship will get locked into the Arctic ice and drift with the ice floes for a year so that scientists can gather unprecedented data about the Arctic climate.
