Isostasy in Greenland - deglaciation of an ice sheet

Research output: Contribution to conferenceConference abstract for conferenceResearch

The large continental ice sheets left a legacy of isostatic upheaval, which is generally aligned in a rather simple pattern consisting of a dome of uplift with its maximum at the centre of the former ice sheet. Owing to the incomplete deglaciation the isostatic signal left by the LGM ice sheet in Greenland is not simple, but composed of several domes with high uplift separated by swales with low uplift. This pattern, which reflects both unloading after LGM and reloading during Neoglacial ice sheet growth, shows that different sectors of the ice sheet responded differently to Holocene warming and subsequent cooling where such factors as local climate, topography, and general drainage conditions modified the effect of the overall temperature signal. We present an updated model of the Holocene isostatic uplift in Greenland based on a compilation of c.700 field observations from all parts of the country, and discuss the implications for deglaciation history.
