Algae and Pollen Grains Provide Evidence of Remarkably Warm Period in Antarctica's History
October 1, 2009
Researchers studying Antarctic sediment core samples gathered as part of the ANDRILL program discovered palynomorphs, or dust-size organic material such as pollen, spores and cysts of dinoflagellates and other algae found in warmer climates. The discovery provides hard evidence that Antarctica underwent a brief but rapid period of warming about 15 million years before the present.
