In early April 2015, a small team of 2 Belgian and 2 French researchers went to Svalbard. The goal? Testing new methods to measure sea-ice thickness and ice algal biomass, but also measuring greenhouse gases in the sea ice in relation with the ‘STeP’ (Storfjorden Polynya multidisciplinary study) campaign. With funding from the French Polar Institute (IPEV) and IPSL and logistical arrangements by t ...[Read More]
Going on a cruise for a month sounds tempting for most people and that is exactly how I spent one month of my summer. Instead of sunshine and 25 degrees, the temperature was closer to the freezing point on the thermometer and normal summer weather was replaced by milder weather conditions. The destination of the cruise was the western Nordic Sea and the east Greenland Margin. The ice2ice cruise wa ...[Read More]
What do polar bears and emperor penguins have to do with the Eiffel Tower and Notre Dame? Pole to Paris has the answer. Erlend Moster Knudsen earned his PhD in climate dynamics after four years of research from the University of Bergen, Colorado State University and University of Alaska Fairbanks on Arctic sea ice and its interaction with atmospheric circulation. He took some time to answer ...[Read More]
– In fieldwork, you have no average. You just have extremes. When Daniel spoke his mind out loud we were facing a bright sunny day coming in from the opening of our tent. We were very glad to see that and ready to engage with our glaciological tasks. Our camp site was at the immediate fore field of the A. P. Olsen ice cap in Northeast Greenland. We had arrived there the previous evening and ...[Read More]
Everyday we come into contact with technology that has changed the way we work, live and even think. Yet it is still easy to forget how integral satellite technology is to our daily lives; over two thousand artificial satellites currently orbit our planet – satellites for navigation, for telecommunication, for meteorology, and for environmental and climate monitoring. The latter two categori ...[Read More]
Only one month after starting my PhD, I found myself in a tiny plane flying over one of the most beautiful and breathtaking landscapes I’ve ever seen. I was on the way to the northernmost settlement in the world – the research village Ny-Ålesund. What I expected from the trip: cold temperatures, darkness, and lots of snow. What I found instead: stunning views, magical colors, friendly people, and ...[Read More]
Mountain glaciers are melting rapidly due to global warming. This process is being intensified by increasingly extreme natural events, such as forest fires and air pollution from human activities. One of the main culprits is a tiny but powerful pollutant called black carbon (commonly known as soot) which darkens the surface of the snow and makes it met faster under the sun. But how much of this po ...[Read More]
Would you like to follow the endeavours of a small team working in the ice-marginal terrain in South-West Greenland? They set out to investigate proglacial lakes using sediment coring, water sampling and gas collections (figure 1), aiming to better understand methane dynamics, proglacial terrain development and the environmental drivers behind methane production in glacially influenced lake system ...[Read More]

Slopes are extensive deposits of moraines and loose rock debris, left behind by retreating glaciers. A small glacial lake (near the center-bottom of the image) fed by meltwater from the surrounding ice and snow was developed after glacier retreat [Credit: Levan Tielidze].](https://blogs.egu.eu/divisions/cr/files/2025/06/Fig0-700x400.jpg)
In this week’s blog, Levan Tielidze tells us about his recent glacier study from the Greater Caucasus. By combining geomorphology, remote sensing, and historical cartography, the team reconstructed nearly 200 years of glacier and climate change across one of the world’s most dynamic cryospheric frontiers. Glaciers’ transformation provides a high-resolution archive of post-Little Ice Age climate dy ...[Read More]
In this week’s blog, Levan Tielidze tells us about his participation in a scientific expedition to Dronning Maud Land, Antarctica, during the 2024–2025 field season. The journey, commencing in Australia and passing through South Africa, led him to the “surreal” and “awe-inspiring” Antarctic landscape. The team, a collaborative effort from Monash University, and the Un ...[Read More]
