PC34A:
History and Development of Greenland Ice and Arctic Sea Ice Posters


Session ID#: 28083

Session Description:
Our understanding of the early history and subsequent development of Greenland Ice along with Arctic Ocean sea ice is evolving rapidly. This program strives to bring interested parties together to discuss these dynamic ideas where we now see Greenland beginning with intermittent ice growth and decay tens of millions of years before previously thought. The same is true for sea ice in the Arctic Ocean. Many new tools are being used in this research as well as new core materials and enhanced age models. Plans are underway for another IODP drilling expedition to the Arctic to supplement ACEX. Arctic records from cores taken across the Arctic are being compared to global records providing a better understanding of the causes for a mid-Eocene initiation of ice on Greenland and in the Arctic Ocean. Yet the more recent rapid wasting of the Greenland Ice Sheet and the diminished extent and duration of the perennial ice cover in the Arctic is of major concern because of the feedbacks to the climate system. This program invites papers on the development of ice in the Arctic regions since its initiation, its history, and interrelationship with the global climate system.
