Chapter 34: The Region Today: Australia and Oceania


Today's scientists may follow the paths of Antarctica's early explorers, but present-day goals involve scientific research rather than exploration. The Antarctic ice cap holds a vast storehouse of information about world climate. In this lesson you will learn about research in Antarctica, the information that ice cores contribute to scientific knowledge, and the work of one expedition from the United States.
