Hi Ronja and Emily, thank you for agreeing to doing this interview. Could you tell us briefly about your background and how you came to research your field? Emily: I have an environmental science/physical geography background and I have been working with an ice sheet model during and after my PhD to understand how glaciers and ice streams in Greenland and Antarctica may respond to climatic changes ...[Read More]

In 2010 EGU held our first annual Photo Competition at the General Assembly in Vienna. Since then hundreds of photos have been shared on imaggeo by geoscientists and researchers just like you, with a lucky few being selected each year to be highlighted during the meeting and voted on by our members. These images can be of anything to do with geology or geoscience – we get many beautif ...[Read More]

At the edge of the Greenland Ice Sheet, surface melt releases old layers of dust, that have travelled thousands of years into the ice. Under sunny weather, the dust heats up with radiation, melts the ice underneath, and thus accumulates in tiny potholes and meltwater creeks. However, this photo was taken after a rainy day. The rain triggered increased melt on the surface of the ice irrelevant of i ...[Read More]

Imaggeo On Monday: Contorted Streams on the Gates Glacier

Allen Pope December 20, 2021

Supraglacial streams in ogives, Gates Glacier

Annual ridges and troughs (called wave ogives) are formed as the ice of the Gates Glacier (in Alaska’s Wrangell Mountains) flows through a steep icefall. Down-glacier, as the ice melts, the rushing meltwater is funnelled into streams, carving ice canyons as it flows, but ultimately directed by these topographic constraints. Description by Allen Pope, after the description on imaggeo.e ...[Read More]
