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 …[Read More]
Each year, the Arctic sea ice goes through a cycle of melting and freezing. From March to September, sea ice gradually melts and becomes thinner, and from October to March, the water freezes again. In our warming climate, we see that more and more ice melts each year. One would expect that the ice would …[Read More]
There are several early career groups, which are affiliated with cryosphere-based research in one way or another. APECS (Association of Polar Early Career Scientists) is an international network that is present during many occasions and events in the world of polar research. Have you ever wondered why busy early career researchers (ECRs) use their time …[Read More]
Have you ever wondered what dark secrets the Arctic sea ice holds during the harsh winter months? Imagine total darkness in the central Arctic, making it almost impossible to gather scientific information. At this time of the year, usually only satellite observations are available. This changed in September 2019 when a team of scientists collected …[Read More]
The Weddell Seal pops his head up through the hole in the floor of the shipping container… for the fourth time today. The shipping container is one of several making up our field camp on sea ice, 40 km from Scott Base – situated on Ross Island, in the south-western Ross Sea. Today I talk …[Read More]
Does measuring the surface of the ice sheets provide more than superficial knowledge of their current status? Read further to find out why the answer is definitely yes! Measuring surface elevation changes actually tells us where Greenland and Antarctica are thinning or thickening and how much they contribute to sea level rise. Scientists have been …[Read More]
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 …[Read More]
In this week’s blog, Levan Tielidze tells us about the insight into the response of mountain glaciers to the Antarctic Cold Reversal (ACR) event in New Zealand to better understand the climatic history of the Southern Hemisphere during the last deglaciation. The ACR was a cold period occurred in the Southern Hemisphere during the transition …[Read More]
> Reflections from an ongoing art-science research project Common Grounds < How to visualize thousands of thousands (> 20,000,000) of data points collected in the Arctic atmosphere and subsurface at a permafrost observatory over 25 years? How to tell the story of permafrost, ground that is permanently frozen and an important part of the cryosphere, …[Read More]
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 …[Read More]
