The sea ice around Antarctica likely had a record low surface area when it was at its maximum size this winter, a preliminary US analysis of satellite data showed Monday.
As the southern hemisphere transitions into spring, the US National Snow and Ice Data Center said in a statement that Antarctic sea ice had only reached a maximum size of 16.96 million square kilometers this year, on September 10.
At its high-point this year, the sea ice was 1.03 million square kilometers smaller than the previous record, roughly the size of Texas and California combined.He added that the growth in sea ice appeared"low around nearly the whole continent as opposed to any one region." There is debate among scientists over the cause of the shift, with some reluctant to establish a formal link with global warming. Climate models have struggled in the past to predict changes in the Antarctic ice pack.is"now thought to be linked to warming in the uppermost ocean layer," the NSIDC said.

Study finds Antarctica's glacial border migrates for miles with the tideThe grounding line of the southern Ronne Ice Shelf in Antarctica can shift up to 15 km with changing tides, new analysis shows. The research, published today in The Cryosphere, examines the key region where land-based Antarctic ice spills over into the surrounding ocean. Observing and understanding the dynamics of this region can help scientists predict Antarctica's response to climate change, and so how much global sea levels will rise.
