Buildling a record of climate change on a geological time scale

Steve Clemens of Brown University and Wolfgang Kuhnt of Christian-Albrechts-University are co-chief scientists for the expedition to the Indian Ocean.

Clues about rainfall in the distant past — from river mud to tiny seashells — come to rest on the ocean floor. Sampling layers of sediment from the Indian Ocean will help researchers build an accurate picture of Indian monsoon activity going back 15 million years or more.
