When it's summer in the Antarctic, winter is in the northern hemisphere, USGS scientific teams along with many other international researchers are on the Antarctic ice studying unprecedented changes in remote polar regions. Their work coincides with the 2007-2008 International Polar Year, and USGS Antarctic and Arctic scientific explorers are dedicated to better understanding the effects of climate change on Earth's ecosystems and people.
On December 13, USGS scientists will be providing an overview of USGS Antarctic programs while explaining how geophysical surveys reveal what lies beneath the ice, how ice cores are providing clues to past climatic conditions, describing why the geographic South Pole survey marker need repositioning, highlighting mapping progress in this frozen frontier, and showcasing the recently completed satellite imagery mosaic of the entire continent.
A panel of invited Antarctic experts will be on hand to answer your questions following the lecture program.
