This video examines what Antarctica looks like today -- how thick the ice cover is, what the continent would look like without ice, and how ANDRILL scientists prepare to work in the coldest, driest, windiest place on Earth. Challenged by a continent covered in ice, how can ANDRILL researchers find any clues at all? This unit shows how ANDRILL scientists detect Antarctica's climate history -- by prospecting, surveying and drilling to read Earth's history in sediments and rocks.

Antarctica is the iciest place on Earth, but not all of the ice on the continent is the same -- nor is it sitting still. Antarctica has both floating ice and land-based ice. What is the difference between ice sheets, ice shelves and sea ice? How does this ice affect the stratification and circulation of global oceans? How does it affect climate? And why does melting sea ice not raise sea level but melting land-based ice sheets do? For more of Antarctica's Secrets, including teachers' guides, visit http://www.netnebraska.org/ice.

This year, Antarctic sea ice reached a record maximum extent while the Arctic reached a minimum extent in the top ten lowest since satellite records began. One reason we are seeing differences between the Arctic and the Antarctic is due to their different geographies. As for what's causing the sea increase in the Antarctic, scientists are also studying ocean temperatures, possible changes in wind direction and, overall, how the region is responding to changes in the climate.
