Give your ears a holiday treat: our favourite polar podcasts

December is a busy month, and while we are busy preparing gifts and a mindful attitude for the festive season, finishing up projects for the year, at some point, we close the laptop and take our ride of choice home. So as a little treat for your ears, we found some 8 (+1) polar podcasts for those in need of a little inspiration. The podcasts are tackled from points of natural science, policy, hist ...[Read More]

UndercoverEisAgenten – Permafrost, drones and young explorers investigating Arctic change

UndercoverEisAgenten – Permafrost, drones and young explorers investigating Arctic change

The “UndercoverEisAgenten” project takes us on a drone journey over the ever-changing permafrost landscapes. Initiated by the Alfred Wegener Institute (AWI) for Polar and Marine Research, the German Aerospace Center’s (DLR) Institute of Data Science, and the Heidelberg Institute for Geoinformation Technology (HeiGIT), this venture is about more than just capturing images. It̵ ...[Read More]

Highlighted Paper: Breaking the ice – what’s new in modeling sea ice deformation

Highlighted Paper: Breaking the ice – what’s new in modeling sea ice deformation

  Most of the time when we speak or read about sea ice it is probably about its extent or thickness or the decline in both, or maybe even about the microorganisms living inside and underneath it. How sea ice breaks and deforms is normally not so much the topic of general discussions. This is actually a really important process that we do not know enough about, at the same time it is pretty co ...[Read More]

Did you know… about worms surviving in permafrost for at least 46000 years?

Did you know… about worms surviving in permafrost for at least 46000 years?

Lately permafrost makes the news more and more because of its enormous carbon stocks and its vulnerability to climate change. While permafrost greenhouse gas budget calculations are complex and harbour an ever-growing research community, its microbial ecology is still on the rise. A recent star are tiny roundworms that survived frozen in permafrost for 46’000 years. Take a short dip into this new ...[Read More]

Small step for reindeer – large leap for humankind?

Photo of a reindeer looking for food on the snow.

Since several decades, there’s a lot of discussion in the permafrost ecosystem community on “rewilding” and “return to a natural state” in order to protect ecosystems and to reduce the impacts of climate change. Reindeer and other herbivores influence the insulation regime of the ground and could thereby preserve the frozen state of permafrost ground. Is there a way to utilise this effect to our b ...[Read More]

Some icy summer reads – the blog goes on holiday

A photo of a sunset over Arctic sea ice and a photo of yellow safety rubber shoes facing that sea.

The cryosphere blog is taking a summer break but not without first providing you with your beach/airplane/train/fieldwork/balcony summer reading list to make you miss us a tiny bit less. Continue reading this post to explore some summer inspiration. Like a lot of northern countries who take long summer breaks to enjoy the long hours of light (midnight sun) after a dark winter, the Cryoblog is also ...[Read More]

Did you know there is light pollution even in the Arctic?

Did you know there is light pollution even in the Arctic?

Light emissions are increasing worldwide and much of the world is light polluted due to excessive and inefficient light use. This has negative consequences for many organisms, such as birds, insects, fish, plants and humans. Even in the high Arctic, which is remote and sparsely populated, and experiences the polar night for a large part of the year, there are artificial light sources which disturb ...[Read More]

Did you know that cracks play a large role in the Arctic sea ice production?

Did you know that cracks play a large role in the Arctic sea ice production?

What do you need to form sea ice? Well, you can start with some sea water, an ocean will do, and cold air above it. Once a layer of ice starts forming, break it to make some cracks. You would have not thought of that? Yet, our recent study suggests cracks in the ice contribute significantly to Arctic winter sea ice production. A relationship between sea ice formation and breakup? We have known for ...[Read More]

Arctic Frontiers Emerging Leaders

Arctic Frontiers Emerging Leaders

Here on the Cryoblog we often talk about the impacts of climate change in the Cryosphere. So now for something completely different: how does this fit into sustainable development in the Arctic? Here, I take you on a journey through the Arctic in a round-up of the recent Arctic Frontiers Emerging Leaders program, a unique early-career and mentoring program bringing together academic, industry, ind ...[Read More]

The Polar Night Week and the Svalbard Integrated Arctic Earth Observing System

The Polar Night Week and the Svalbard Integrated Arctic Earth Observing System

In the early days of 2023, nearly 100 researchers gathered in Longyearbyen, Svalbard, one of the last permanently inhabited places before reaching the North Pole (see my previous blogpost about Svalbard). The Svalbard Integrated Arctic Earth Observing System (SIOS) held its fifth Polar Night Week. SIOS is an international partnership of research institutions that study the environment and climate ...[Read More]
