Moving on from Vostok: a new generation of deep ice cores
Within the last twelve months, a new generation of ice core drilling projects have reached the bedrock in Greenland (the NGRIP project), and in Antarctica (the EPICA project at Dome C, and the joint British/French project on Berkner Island), while a fourth is likely to reach the bed in Dronning Maud Land, Antarctica, in the coming season. The NGRIP core extends slightly the earlier Greenland climate records from the GRIP and GISP2 ice cores, while the Dome C core will more than double the length of climate record from Vostok. Yet, there is still a place too for shorter regional ice core climate records. In this talk, I will describe some of the new data from the deep cores, but also show the effort that goes into deep ice core drilling by focussing on the Berkner Island project, which recently reached the sandy base of the ice sheet - only the fourth ice core ever to reach the ice sheet base in Antarctica. Despite the recent successes, it still doesn't seem to be enough, and the ice core juggernaut rolls onwards with new ambitious projects to extend the records still further back in time, which I will briefly outline.
25th May
Dr. Richard Essery (University of Wales, Aberystwyth)
