Cruising for mud: Sediments from the ocean floor as a climate indicator

Cruising for mud: Sediments from the ocean floor as a climate indicator

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]

From the Poles to Paris — An interview with Erlend Moster Knudsen

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]

Only extremes – Babis Charalampidis

Only extremes – Babis Charalampidis

– 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]

­Around the Poles in approx. 100 minutes: Earth Observation for Climate Science and the Cryosphere – Anna Maria Trofaier and Anne Stefaniak

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]

Did you know: Soot is a melting agent for glaciers in Peru and China

July 25, 2025
Collecting snow samples from the Puruogangri Ice Cap on the Tibetan Plateau, China.

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]

The Proglacial Puzzle: Sampling of Glacier-fed Lakes in Greenland

July 11, 2025
The Proglacial Puzzle: Sampling of Glacier-fed Lakes in Greenland

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]

Tracking the Footprints of a Vanishing Glaciers in the Greater Caucasus

June 13, 2025
Aerial image showing the climate change impact on small glaciers in the central Greater Caucasus, Georgia. 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].

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]

A Scientific Quest from Australia to Antarctica

May 29, 2025
A group of 10 individuals forming the team for the fieldwork

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]

Field notes from the Chhota Shigri Glacier: A journey of science and survival in the Himalaya

January 10, 2025
Weather station on the snow

I’m Himanshu Kaushik, a PhD student working under the guidance of Dr. Mohd Farooq Azam at the Indian Institute of Technology Indore (India). Seven years ago, I took my first steps onto the Chhota Shigri Glacier (CSG) in the Indian (Western) Himalaya, and it felt like stepping into another world. Surrounded by the towering peaks, it seemed otherworldly and humbling. After that first expeditio ...[Read More]
