Cryosphere Caps: PhD hats and the researchers that wear them – Episode 1

February 21, 2025
Cryosphere Caps: PhD hats and the researchers that wear them – Episode 1

This miniseries features the tradition of ‘PhD hat’ making in German research institutes and universities. For those of you unfamiliar with this idea (as I once was), this is one of the final milestones a graduate student has before they are officially a “Dr.”. Upon the successful defense of a thesis, the peers of the PhD student craft a graduation hat from a mishmash of scrap cardboard and memora ...[Read More]

Cryoscientist life stories: Experiences of an ‘office glaciologist’

August 29, 2024

Both glaciological research conducted in the field, and in the office, are vital — and ‘count’ as glaciology. Often, however, those of us who remain in our cozy offices can be forgotten, or thought to lead a ‘boring’ job. Alex Bradley, a modeller of glaciers, is here to remind you why the office glaciologist is fundamental to the Cryosphere, and why glaciology from a distance is key to the future. ...[Read More]

Climate Change & Cryosphere – Can the smallest ice make the greatest impact?

June 28, 2024
Climate Change & Cryosphere – Can the smallest ice make the greatest impact?

The cryosphere comprises all the ice on Earth, from glaciers in Antarctica, icebergs floating in the ocean, to millimetric ice found in the soils. Soil can hold ice wedges and ice lenses, but there are small ice reservoirs that are usually overlooked: the pore ice. Pore ice is an unknown compartment whose role regarding matter degradation is yet to be determined… stay with us and you will see that ...[Read More]

Blue ice in Antarctica: small extent, big science

June 21, 2024
A figure with a map of Antarctica in the middle, and 8 zoomed in sections of it showing blue ice areas.

Kggk kggk kggk – the sound of crampons accompanies me. A thin layer of snow covers the slippery ice while I pull a sled. As I wipe my hand over the snow, underneath, a blue color glitters in the sun (Figure 2). In the last days it has been snowing in the White Desert (Antarctica). All blue ice we could see before is temporarily covered by a thin blanket, perfect to pull a sled. However, this snow ...[Read More]

Cryo Comm – Explaining ice core science with “cool” educational videos

Mastering the art of science communication is becoming more and more important, especially in the realm of climate science! Training and practice can really help PhD students acquire this skill. With this in mind, the DEEPICE project, a training network of 15 PhD students, has developed a wide range of activities to train the DEEPICE students, including the creation of a series of educational vide ...[Read More]

Did you know? We can see what’s going on inside an ice shelf using geophysics!

April 2, 2024
Did you know? We can see what’s going on inside an ice shelf using geophysics!

Understanding what is going on inside an ice shelf is important for many reasons. But mostly, it allows us to better understand their contribution to sea level rise, and to understand how they are changing and evolve over time, with our changing climate. Geophysical methods offer a means to be able to see inside an ice shelf, and get an idea of their properties. Read on to find out a bit more abou ...[Read More]

Ice-Hot News – You have a “cool” new Policy Point of Contact in the Cryosphere Division!

February 2, 2024
Ice-Hot News – You have a “cool” new Policy Point of Contact in the Cryosphere Division!

At the 2023 EGU General Assembly, our cryosphere division members all voted “YES!” to have a division policy point of contact! If you’re wondering how to engage in science policy at our division level, what a division policy officer does, who was named and what happened next… This blog post should answer a lot of these questions (or I hope)! First off, a little history about how policy officers ca ...[Read More]

Recipe to quantify calibration errors in a time-dependent ice sheet model

Recipe to quantify calibration errors in a time-dependent ice sheet model

Ice sheet models are awesome tools that help us learn and predict the fate of ice sheets under human-induced climate change. However, all models have errors. What types of uncertainties exist in an ice sheet model and how can we quantify some of them efficiently? Check out our recipe to quantify one type of uncertainty in sea level rise projections: The model calibration error. Not a numerical mod ...[Read More]

Hidden Ice of the Greater Caucasus

June 30, 2023
Hidden Ice of the Greater Caucasus

In this week’s blog, Levan Tielidze tells us about the first inventory of rock glaciers from the Greater Caucasus as an important basis for further research of geomorphology and palaeoglaciology in this region. What are Rock Glaciers? Rock glaciers are distinctive geomorphological landforms of frozen debris that are supersaturated with ice. The low ice velocity or certain speed of movement and per ...[Read More]

Did you know the mystery of the ice-cold rose?

April 21, 2023
Did you know the mystery of the ice-cold rose?

Darkness. Freezing cold. Thin layers of ice cover the wide Arctic Ocean. It is the time of the last dusk. You can almost see Fenris wolf chasing the sun to devour it, almost hear his howling as darkness falls. Fimbulwinter has arrived. But what is this? A flower? Out here on the Arctic Ocean? This is strange, so let us take a closer look at the mystery of the ice-cold rose. Where the Wild Roses Gr ...[Read More]
