Wake up every one – permafrost microbes feasting – greenhouse gases go

Wake up every one – permafrost microbes feasting – greenhouse gases go

I really like to combine science and art. This puts science in a larger perspective and can help understand it in different ways. And perhaps more importantly, it evokes emotion. I wrote haikus and created stencils for every chapter of my PhD thesis. I created these artworks to illustrate the dimensions of the permafrost region and the consequences of global warming on permafrost. Let me show you ...[Read More]

The intriguing order of cold terrains

Do you know what the periglacial environment is? Well, the word periglacial refers to those environments which are somehow sculpted by seasonal freeze and thaw cycles. The alternation of freezing and thawing conditions can change the landscape, creating some spectacular landforms. Stone circles are certainly among the most mysterious and fascinating. Come and discover them! Some definitions Glacia ...[Read More]

phase-sensitive Radio Echo Sounder, a.k.a. pRES, For Dummies

Greetings! My name is Reza. I’m (still) A PhD candidate in Geophysics and Glaciology at the University of Tübingen in Germany. Today, I will tell you all about a device named pRES, a radar system designed to study ice. Well, pRES and I have had an immense love/hate relationship during the last four years. It is one of the main tools I have used during my PhD, working in the Alps and Antarctica. I ...[Read More]

Why the 2022 Italian snow drought matters to you

June 2022: I was discussing the ongoing drought with my family over lunch, when my dad pointed to me and summarized things as follows: “You know, less snow in winter means less water in summer!” I almost choked … what? Not only was it the first time I realized my family had been listening to my scientific anecdotes for years, but I also had concrete evidence now that snow was entering public ...[Read More]

A new glacier chronology from New Zealand

In this week’s blog, Levan Tielidze tells us about the new glacier history from the Southern Alps of New Zealand, an important piece of information to better understand the climatic history of Earth during the Quaternary, the current geologic period. Quaternary glaciations Geochronological dating of glacial moraines is useful for determining the extent and timing of past glaciation and for reconst ...[Read More]

Lights out: cryosphere instruments perfectly placed to study solar eclipse

On 04 December 2021, only a handful of people in Antarctica were fortunate enough to experience a total eclipse. As well as spectacular views—including a brief window of totality that darkened the midnight sun for 2 minutes—this phenomenon is known to affect the flow of energy between the Northern and Southern hemispheres of the ionosphere. Because eclipses in Antarctica only happen once every ~20 ...[Read More]

Summer 2022: A perfect storm for Alpine glaciers

The summer of 2022 is shaping up to be a perfect storm for Alpine glaciers. By a strange coincidence, all the factors that could adversely affect glacial dynamics seem to have come into agreement. Let’s find out why. What controls the behavior of Alpine glaciers? Snow, temperature, weather conditions and the properties of snow and ice. These are the most important factors governing the life ...[Read More]

The Cryosphere meets the Twittersphere

Twitter is a place that can be full of an overwhelming amount of information, and often it becomes difficult to hear about new information amongst the noise of all the tweeting. To help our fellow cryo-enthusiasts learn more about equality, diversity and accessibility within the cryosphere, we’re highlighting a few twitter accounts that we think everyone should follow! Gender equality: @womeninPol ...[Read More]

What are Snow Mechanics and why should we care?

June 10, 2022
What are Snow Mechanics and why should we care?

Every time we walk, ski, drive or build upon snow, we’re relying upon the theory of Snow Mechanics; but what is that and why should we care?  Mechanics is the engineering terminology used to describe “the branch of applied mathematics dealing with motion and forces producing motion” (Oxford Languages) or more simply, the study of motion, in our case the motion of snow. What causes snow to move? Ge ...[Read More]

Did you know… that glaciers can sing?

Have you ever wondered what the voice of a glacier sounds like? Well, listen here! And if you want to know how the glacier makes these sounds, then let’s take a walk on the ice side… Close your eyes and think of the time you were in the middle of the mountains. On a snow plain, a glacier or a frozen lake; just you. You hear your footsteps in the snow, crunching ice. The wind blows through your hoo ...[Read More]
