  • EastGRIP

    previous deep ice core sites. It is located at the onset of the largest ice stream in Greenland (NEGIS - North-East Greenland ice stream). Ice streams are not very well represented in large scale ice sheet models [...] contribution to sea level projections is thus not very well constrained and a source of uncertainty. Three regimes can be identified which control the effectivity and fate of ice streams: (1) the ice front at [...] EastGRIP ice core can contribute to understand regime (3) and will bring us further towards answering the question: Which conditions of the ice sheet and which physical properties of the material ice help
