Division on Cryospheric Sciences

President: Carleen Tijm-Reijmer (cr@egu.eu)
Deputy President: Nanna B. Karlsson (nbk@geus.dk)

The cryosphere are those parts of the Earth and other planetary bodies that are subject to prolonged periods of temperatures below the freezing point of water. These include glaciers, frozen ground, sea ice, snow and ice. One of the main aims of the EGU Division on Cryospheric Sciences (CR) is to facilitate the exchange of information within the science community. It does so by organising series of sessions at the annual EGU General Assembly, and through the publishing of the open-access journal The Cryosphere. The division awards the Julia and Johannes Weertman medal for outstanding contributions to the science of the cryosphere.

3 Reasons to engage in early career networks

There are several early career groups, which are affiliated with cryosphere-based research in one way or another. APECS (Association of Polar Early Career Scientists) is an international network that is present during many occasions and events in the world of polar research. Have you ever wondered why busy early career researchers (ECRs) use their time also for volunteering in such groups? Today, three members from the board of APECS Germany will give you their reasons why. “Learning by doing” – …


Did you know about the dark secrets of Arctic sea ice?

Have you ever wondered what dark secrets the Arctic sea ice holds during the harsh winter months? Imagine total darkness in the central Arctic, making it almost impossible to gather scientific information. At this time of the year, usually only satellite observations are available. This changed in September 2019 when a team of scientists collected in situ and airborne data in the central Arctic as part of the year-long international MOSAiC expedition. In the following, I will show how we …


Image of the Week – Receiving messages from the deep

The Weddell Seal pops his head up through the hole in the floor of the shipping container… for the fourth time today. The shipping container is one of several making up our field camp on sea ice, 40 km from Scott Base – situated on Ross Island, in the south-western Ross Sea. Today I talk about the sub-ice platelet layer, which provides the base for a rich marine environment. Generating supercooled water from melted ice shelves This water is as …


For Dummies: Radar altimetry for measuring ice sheet elevation changes

Does measuring the surface of the ice sheets provide more than superficial knowledge of their current status? Read further to find out why the answer is definitely yes! Measuring surface elevation changes actually tells us where Greenland and Antarctica are thinning or thickening and how much they contribute to sea level rise. Scientists have been doing this for the past three decades, so keep on reading to find out exactly how this is possible thanks to radar altimeters flying hundreds …

Current issue of the EGU newsletter

In the February newsletter, we hear of exceptional stories from extraordinary women and alternative career options for women in science. Women scientists also tell us the importance of being role models to the younger generation and how other young girls and women can embrace careers in science.

We have heard the expression ‘making a mountain of a molehill’. But most women cannot report a molehill, and most men do not think they are part of the problem. Ingrid Anell examines this complex web, the challenges that hinder gender equity and ways to keep women in academia.

This is your reminder that registrations are open for EGU23! Members of the media are eligible for free registration to the General Assembly, see more here. Stay tuned for our next monthly Update from our conference organiser Copernicus, arriving early March. We recommend subscribing to all Updates here until the upcoming General Assembly in April.
