High basal melt rates explained

Our findings published last week show the Greenland Ice Sheet is melting faster than we thought. Much faster in fact, and – surprisingly – from the bottom up. The news media caught on to this. So, what’s going on at the bed? Here is a (non-technical) explainer: To record basal melt rates, we used a[…]

RESPONDER in the news

Our observation of high basal melt rates beneath the Greenland Ice Sheet is in the news. The findings published earlier this week in the Proceedings of the National Academy of Sciences has been reported by New Scientist, Vox, CNN, Spiegel and quite a few other news outlets. Kudos, Tun Jan Young for installing the ApRES[…]

RESPONDER boreholes shed new light on hydrological systems at the ice-bed interface

Subglacial hydrological systems lubricate the basal motion of glaciers. In Greenland, few observations exists and it is our core mission in RESPONDER to address this paucity of observations by drilling boreholes to the base of Store Glacier (Sermeq Kujalleq). In a new study, we report detailed measurements of the response of subglacial water pressure to[…]

New 3D model of Store Glacier explains complex behaviour of Greenland’s marine-terminating outlets

Our project has created what is perhaps the most sophisticated 3D model of a glacier today. Our model is presented in full-Stokes 3D and features evolving hydrological systems, plume-induced melting at the submerged glacier front and iceberg calving. When the model is applied to Store Glacier (Sermeq Kujalleq) we found significant differences in behaviour during[…]
