Imaggeo On Monday: Contorted Streams on the Gates Glacier

Imaggeo On Monday: Contorted Streams on the 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]

GeoTalk: Meet Larissa van der Laan, glaciologist and science-artist!

GeoTalk: Meet Larissa van der Laan, glaciologist and science-artist!

Hi Larissa, thankyou for spending time with us today! To break the ice, could you tell us a little about yourself and your research? Ha, I see what you did there. I’m Larissa, she/her, 29, and a PhD candidate at the Institute of Hydrology and Water Resources Management in Hannover, Germany. I’ve been fascinated by snow and ice since I was little, writing my first ever school report and ...[Read More]

Imaggeo On Monday: Ice caves in high altitude karstic areas

Imaggeo On Monday: Ice caves in high altitude karstic areas

High altitude karstic environments often preserve permanent ice deposits within caves, representing a lesser-known portion of the cryosphere. Despite being not so widespread and easily reachable as mountain glaciers and ice caps, ice-caves preserve a great deal of information about past environmental changes and paleoclimatic evolution. Since one of their main characteristics is to have ground-ice ...[Read More]

#vEGU21: #EGUartKIDS Hall of Fame – Extreme e-ART-h!

The EGU Kids Art activity normally happens in person in the creche at the conference centre during the General Assembly, but first last year and now this year we have had to move all our activities online instead. Working together – two of our Division Early Career Scientist teams, one from Natural Hazards and one from Cryospheric Sciences came up with this year’s theme ‘Extreme ...[Read More]
