Environmental change profiled in Greenland Ice Core Record


  • Anonymous


The longest continuous high-resolution record of climate response available in the Northern Hemisphere, covering approximately 250,000 years, is the focus of Union sessions U31D, U32C, and U41B, “Climate from Central Greenland Core Records I, II, and III.” This climate record has been provided by the Greenland Ice Sheet Project 2 (GISP2), which successfully reached bedrock on July 1, and its European-led counterpart, the Greenland Ice Project (GRIP). Presentations will focus on information obtained from analyses of the over 3,000-m-deep ice core samples retrieved by both projects. These analyses cast light on atmospheric and environmental conditions during selected periods and on correlations between selected environmental or atmospheric components and changes in climate in Greenland.

P. A. Mayewski and his group will present examples of how important signals extracted from the glaciochemical record provided by the ice core have been developed into paleoenvironmental interpretations of abrupt changes in atmospheric circulation, sea ice distribution, and other environmental boundary conditions during major periods of climate change.
