Scientists blog from Antarctica and provide a glimpse of what it's like to do research in the field. 
What's hot in the news around climate and sea ice and what are scientists talking about now? 
What is the difference between sea ice area and extent?
Scientists may report different numbers for how much Arctic or Antarctic sea ice exists at a particular time. Different satellite sensors “see” sea ice differently, but another factor is whether scientists measure sea ice area or sea ice extent.
Is the Arctic Ocean a carbon sink?
We’ve all heard it: Arctic sea ice is melting. Sea ice is thinner year to year and there is less of it. In 2007, scientists observed a nearly 50 percent loss of summer ice as compared to 1980. With such a dramatic shift, what else is taking place in the Arctic Ocean?
What is under Greenland’s ice?
We have been watching surface melting of the Greenland Ice Sheet (see Greenland Ice Sheet Today) as one sign of climate change.
Can liquid water persist within an ice sheet?
Scientists have discovered a large aquifer, the size of Ireland, near the surface of the Greenland Ice Sheet.
