Associate professor Bo M. Vinther is a specialist in the climatic interpretation of Greenland ice core water isotope data. Furthermore he has worked closely together with the Climatic Research Unit in Norwich and the Danish Meteorological Institute in order to extend and homogenize meteorological observations from Greenland - a prerequisite for doing advanced statistical analysis of the climate signal in the Greenland ice cores. Currently Bo M. Vinther is a PI in the Ice2Ice ERC synergy project, thus closely collaborating with climate scientists at Uni Research and the Bjerknes Centre.

 

Abstract:

The Renland ice cap is situated on a high elevation plateau in the Scoresbysund area in Eastern Greenland. Two ice cores have been drilled through the ice sheet in 1988 and 2015 respectively. The latter core containing a continuous record spanning the last 120,000 years. Interestingly the water isotope signal in the two cores is similar, but quite different from what is observed in ice cores from the Greenland ice sheet. The ice flow in the Renland ice cap seems to be heavily influenced by the mountainous bedrock topography, nevertheless a surprisingly simple ice flow model seems to describe the layer thinning in the two ice cores very well.

 

Arranged date for the seminar talk: Sep 10, 2018
