If glaciers could speak, you might imagine them saying – “HELP!” The planet continues to warm and this means glaciers continue to shrink. Our new image of the week shows a glacier that appears to be making this point in a rather dramatic and gruesome way – it appears to be bleeding! If you went to the snout of Taylor Glacier in Antarctica’s Dry Valley region (see map ...[Read More]

At first glance our image of the week may look like an ordinary stoney beach…but if you look more closely you will see that this beach is not, in fact, covered in stones or pebbles but balls of ice! We have written posts about many different weird and wonderful ice formations and phenomena (e.g. hair ice or ice tsunamis) here at the EGU Cryosphere blog and here is another one to add to the l ...[Read More]

While the first week of COP22 – the climate talks in Marrakech – is coming to an end, the recent election of Donald Trump as the next President of the United States casts doubt over the fate of the Paris Agreement and more generally the global fight against climate change. In this new political context, we must not forget about the scientific evidence of climate change! Our figure of the week, tod ...[Read More]

When working in the middle of an ice sheet, you rarely get to experience the amazing wildlife of the polar regions. So what are we doing hundreds of kilometres from the coast with an animal tracker device? We are listening to the snow of course! It is not crazy; It is what Image of the Week today is all about! Going Wireless In June 2016, Liz Bagshaw and I travelled to the EGRIP (East Greenland Ic ...[Read More]

Image of The Week – Prize Polar Pictures!
Permafrost thawing and its impacts on reindeer breeding.. This figure was created by Noémie Ross - a young graphic designer and illustrator from Montréal, Canada., as part of the ‘A Frozen-Ground Cartoon’ project. It won 1st place at the 2016 Fall APECS International Polar week figure competition. Click here to enlarge the image.

Last week was the Fall APECS International Polar Week, designed to promote and celebrate the great collaborative science that goes on around the world to further our understanding of the polar regions. Part of this celebration was a figure competition, to find the most “eye-catching, informative and inspiring” figures that illustrate aspects of polar science. What better, we thought, t ...[Read More]

“Tsunami“ is a word that became world famous after the so-called Christmas tsunami in 2004, when enormous waves hit the shores around the Indian Ocean with disastrous consequences for countries such as Sri Lanka, Thailand, Somalia and many others. But did you know that tsunamis can be icy? An ice tsunami is one of the many names associated with ice shoves (or ivu, shore ice override, i ...[Read More]

The 30th August 2016 marks 100 years since the successful rescue of all (human) member of Shackleton’s Endurance crew from their temporary camp on Elephant Island (see map). Nearly a year prior to their rescue they were forced to abandon their ship – The Endurance – after it became stuck in thick drifting sea ice, known as pack ice, trying to navigate the Weddell Sea. It was the last major e ...[Read More]

What word would you use to characterise the Antarctic ? White? Windy? Remote? Empty? Inhospitable? Wild? Preserved? While all of these are true it may surprise you to find out that the Antarctic is occupied by humans all year round with almost half of its 82 research stations operating 365.25 days a year! Just a few hours before the launch of the biennial Antarctic meeting held by the Science Comm ...[Read More]

No need to be a superhero to momentarily escape your everyday life! For that you, can just rely on the EGU Cryosphere Blog, which cares for taking you on trips to all sorts of remote and cool places (OK, OK we have to admit that some of these places are indisputably cold 🙂). The picture of this week was taken through the porthole of a boat in the middle of Isfjorden, one of the largest fjord in Sv ...[Read More]

  When you go down to the woods today you’re in for a big surprise….. hair ice!  Did you know that there is a type of ice called hair ice? It is shaped like fine, silky hairs and looks like white candy floss. It grows on the rotten branches of broad-leaf trees during humid winter nights when the air temperature drops slightly below 0°C. A 100-year-old theory states that hair ice a ...[Read More]
