In high-school, I learned in a textbook that glaciers are melting. My teacher said that what was written in that textbook was right, and that was it. There was no proof, no explanation, no scientist’s testimony. All of that, I discovered much later during my studies in the geosciences. Yet as the global temperatures keep rising, and our politicians apply rigorously the “keep calm and carry on” mod ...[Read More]

Cryo Adventures – Installing a weather station on the Greenland Ice Sheet

Soaking up the sun and recharging batteries on a peaceful and quiet summer day, or fighting to stay upright during extreme snow storms in the middle of winter, while continuously recording valuable air temperature, pressure, wind-speed and so much more – such is the life of an automatic weather station on the Greenland ice sheet. Even though they are so remote, sitting by themselves surround ...[Read More]

Cryo Adventures – Droning on glaciers and ice caps in Kyrgyzstan

Drones are not only a cool toy to play with. They are also a useful instrument to monitor and study glaciers and ice caps. By taking thousands of images flying above the ice, we can make 3D models of ice masses at centimetre resolution. Using drones, we can now survey small to medium sized glaciers and ice caps in unprecedented detail. In recent years, we have conducted several surveys on glaciers ...[Read More]

Those of us fortunate to participate in cryo-fieldwork are well aware of the unique, hilarious, and sometimes bizarre scenarios that we often find ourselves in. For this year’s April Fool’s Day, the EGU Cryosphere Blog team shares crazy anecdotes, with a catch: one of these stories is fake! Are you able to tell fact from fiction? Fill in the (twitter) poll, and time will tell if you are right…!! W ...[Read More]

I have just returned from nearly three months in Nuuk, the capital of Greenland, where I was doing my PhD placement at Asiaq Greenland Survey. Read on to find out what science I got up to… everything from mapping mountain glacier snowline change to avalanches! How do you map glacier snowline evolution? During my PhD research placement, I was working at Asiaq Greenland Survey in their Hydrolo ...[Read More]

Will the ice break out? – a story from the farthest north ice trails

"For over two decades, the sea ice group at the University of Alaska has worked with the community of Utqiaġvik, establishing an integrated observing network. This network includes local observations, a coastal radar system to monitor ice conditions, an in-situ mass balance site monitoring environmental change such as ice growth and snow cover, and the mapping of community sea ice trails." In thi ...[Read More]

Cryo-adventures: Ninja goes south – Life and science onboard an icebreaker in the Weddell Sea (Antarctica)

Hello there! I’m Ninja – a curious little LEGO-figure who doesn’t know much about the cryosphere, but who’s learning! Maybe you read about me in the blogpost by ice sheet modeler Petra Langebroek a few years ago? She brought me to the ice-core drilling camp called EASTgrip, on top of the Greenland icesheet. Together, we wrote a photo-novel to tell her sons and all of you about life and science at ...[Read More]

Of Polar Bears and Sediment Cores: a Scientific Cruise in the Arctic

Of Polar Bears and Sediment Cores: a Scientific Cruise in the Arctic
One of the most stunning views of the trip, and one every glaciologist dreams of: a calving front in the sunshine. This is the terminus of Etonbreen, a glacier that is part of the Austfonna ice cap, an ice cap located on the island of Nordaustlandet, northeastern Svalbard. Photo credit: Agust Gustavsson.

Through the scientific excursion part of the University Centre in Svalbard (UNIS) course ‘Arctic Late Quaternary Glacial and Marine Environmental History’, a few lucky grad students got to visit Nordaustlandet, northeastern Svalbard. This is the story of our research adventure in this beautiful, remote part of the Arctic. On a bright and early morning in late August, a group of 16 students, 4 prof ...[Read More]

Vernagtferner: My First Encounter with an Alpine Glacier

In July 2021, together with a group of MSc students from the University of Bremen, I set off from the flat plains of Northwest Germany and embarked on a journey to the mountainous regions of Austria, with the Vernagtferner Glacier as our final destination. My aim was to learn as much as I could in the glaciology field course offered by the university. During my student days in Brazil, glaciers fil ...[Read More]

We are used to think of algae as marine or lacustrine organisms, but they are actually able to thrive also on the cryosphere. In a previous post, we learnt how snow algae live and reproduce on snow. Now we will explore how and why scientists study snow algae, and how social media can be used for identifying new study areas. Snow algae in the Alps Snow algae in the Alps have been overlooked or conf ...[Read More]
