A group of scientists from around the country, directed by The Institute for Quaternary and Climate Studies at the University of Maine, have embarked on a four-year expedition to better understand how humans have affected Antarctica's environment and what the lasting effects on the world might be. They go to Antarctica to study everything from astronomy to zoology. From their discoveries we know that Antarctica is a vital part of the earth's ecosystem, affecting both atmospheric circulation and circulation of deep ocean waters, two key elements in the global weather system. We also know that Antarctica's environment has changed over geologic history and continues to change today.\n\nExpedition Site\n
