Moving 150 tonnes of equipment more than 450km across the Greenland Ice Sheet sounds like a crazy idea. In that context, moving a 14-metre high, dome-shaped, wooden structure seems like a minor point, but it really is not. I do not think I realised what an awesome and awe-inspiring project I was part of, until I was out there, in the middle of the blindingly white ice sheet, and I saw the enormous ...[Read More]

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

Sophie Berger June 29, 2015

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]

Ice Nomads: The iSTAR traverse of Pine Island Glacier, West Antarctica

Damon Davies May 27, 2015

It’s the 2nd December 2013 and I find myself in one of those rare occasions in life where I feel I need to pinch myself to see if I’m dreaming. Why? Somehow I’m in control of a British Antarctic Survey De Havilland Twin Otter aircraft flying over the white featureless expanse of the West Antarctic Ice Sheet. I’m part of a team of 12 heading to Pine Island Glacier, a remote ice stream 75°S and arou ...[Read More]

19 November 2014, the Iliuchine 76 gently lands on the runway of the Russian Antarctic station, Novolazarevskaya, in Dronning Maud Land. For the first time, I’m in Antarctica! It is 4 o’clock in the morning and we need to hurriedly offload 2 tons of material intended for our field mission near the Belgian Princess Elisabeth Station. I’m deeply impressed by the landscape although it is dotted with ...[Read More]

Young Scientist Events at the EGU General Assembly

Nanna B. Karlsson April 12, 2015

Are you going to the EGU General Assembly in Vienna next week? Check out these events for young scientists (YS). Short courses The idea behind the young scientist short courses is to give an insight into a certain area and/or the applications/uses/pitfalls in and around the topic. There are a lot of very interesting courses at this year’s meeting. I would like to highlight two short courses in par ...[Read More]

Glaciers on Mars

“I did not know that there is water on Mars!” This a sentence I hear surprisingly often when I talk about glaciers on Mars. In fact, it has been known for some time that water exists in the form of ice and water vapour on the planet. For example, water ice layers several kilometres thick cover the Martian poles, and the ground close to the Polar Regions has permafrost patterns very similar to what ...[Read More]

High-tech science, old-school ship – Anne-Katrine Faber and Malte Winther

Nanna B. Karlsson March 17, 2015

Last summer we got the chance to participate in an incredible Arctic expedition. The mission was clear and yet unclear at the same time: Bring your fanciest laser technology on a wooden schooner. Then cross the Atlantic and sail to the fjords of southern Green land and conduct science throughout the journey. During most of our expedition, our “scientific lab” contained icebergs, glaciers and beaut ...[Read More]

A story about CO2 -fluxes between sea-ice and the atmosphere What’s it all about? Whenever I have had to describe my PhD research project to people outside of my research community, I have always found it useful to use an analogy most people are familiar with, namely beers. Now that I have the full attention of the entire class, allow me to explain. Say you were to find yourself at an outside café ...[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]

The Tibetan Plateau – area: 2.5 million km2, mean elevation: 4,700 m a.s.l., surrounded by a series of high mountain ranges that are home to some of the world’s highest peaks: Himalayas, Karakoram, Pamir, Kunlun Shan. Considering these characteristics and the unique cultural heritage of Tibet the decision was easy when I was asked if I am interested working in a project on the regional patterns of ...[Read More]
