Antarctica's Ice on the Move - Antarctica's Climate Secrets
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.
