Amundsen Sea Drifts: Indications for Changing Climate and Oceanographic Conditions

The analysis of seismic reflection data from the Amundsen Sea, southern Pacific Ocean reveals sediment drift formation already in Eocene/Oligocene times. This observation indicates bottom current activity and hence a cold climate for the late Paleogene in an area, which today lies under the influenc...
