The orientation of ice-crystal grains in glacier ice locally co-evolve with and can enhance the flow of ice. Inferring the grain orientation structure inside glaciers and ice-sheets is therefore …

The EastGRIP ice core is located in an ice-stream on the eastern flank of the Greenland ice-sheet. Deeper and older ice in the ice core will have originated upstream from the drill site. In this …

It is not often that negative results gets published in a high impact journal. Here, we highlight the absence of a systematic pattern in the anatomy of abrupt changes as recorded in different ice …

Ice with a strong fabric deforms more readily in some directions. Nicholas Rathmann levels up the theory with a better treatment of how grains influence bulk properties. The impact can be an order of …

The Northeast Greenland Ice Stream (NEGIS) extends around 600 km from its onset in the interior of Greenland to the coast. Several maps of surface velocity and topography in Greenland exist, but …

Weather variability has a profound impact on the mass balance of ice sheets, and the equilibrium volume of ice sheets. We illustrate this in a simple ice sheet model and find that the equilibrium ice …
