The ice microstructure in the lower part of the North Greenland Eemian Ice Drilling (NEEM) ice core consists of relatively fine-grained ice with a single maximum crystallographic preferred orientation (CPO) alternated by much coarser-grained ice with

Mass loss from ice sheets contributes to global sea level rise, and accelerated ice flow to the oceans is one of the major causes of rapid ice sheet mass loss. To understand flow dynamics of polar ice sheets, we need to understand deformation mechani

The upper 2121 m at EastGRIP - Results from physical properties of NEGIS

Autor: Sérgio H. Faria, Tomoyuki Homma, Julien Westhoff, Jan Eichler, Ilka Weikusat, Kumiko Azuma, Steven Franke, Nobuhiko Azuma, Wataru Shigeyama, Tomotaka Saruya, Sepp Kipfstuhl, Nicolas Stoll, Dorthe Dahl-Jensen, D. Wallis, Ernst-Jan Kuiper, Daniela Jansen, Johanna Kerch

Here we present the ice microstructure and CPO (c-axes fabric) data from the upper 2121 m of the EastGRIP ice core, an on-going deep drilling project on the North East Greenland Ice Stream. Understanding ice flow behaviour of fast flowing ice streams

Using a composite flow law to model deformation in the NEEM deep ice core, Greenland: Part 1 the role of grain size and grain size distribution on the deformation of Holocene and glacial ice

Autor: Martyn R. Drury, Johannes H. P. de Bresser, Gill Pennock, Daniela Jansen, Ilka Weikusat, Ernst-Jan Kuiper

The effect of grain size on strain rate of ice in the upper 2207 m in the North Greenland Eemian Ice Drilling (NEEM) deep ice core was investigated using a rheological model based on the composite flow law of Goldsby and Kohlstedt (1997, 2001). The g
