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? 
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.
What about that hole in the sea ice?
There’s been discussion about a big opening in sea ice, called a polynya, and if it had anything to do with the Russian expedition ship, Akademik Shokalskiy, getting stuck near the Antarctic coast. The answer is not so straightforward.
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.
