Sediment cores reveal how Greenlandic glacier melts

The melting of the sea ice in the Arctic and the faster melting of Greenland’s ice cover are two prominent environmental changes that could accelerate sea level rise in the future. Researchers are therefore working on a broad front to better understand the mechanisms behind the melting ice and what consequences it will have. Matt O’Regan is a researcher at the Department of Geological Sciences at Stockholm University. His research … Läs mer…

“One of the most successful expeditions”

The Ryder 2019 Expedition with Swedish icebreaker Oden took place from early August to mid-September 2019 and included marine as well as land-based research. The overall scientific goal was to gain a better understanding of how climate affects the sensitive high Arctic environment.

Antarctic expedition documents cultural heritage

Thawing permafrost may affect the historical remains of the first Swedish Antarctic Expedition, conducted in 1901–1903. Now, the Argentine-Swedish research expedition CHAQ 2020 will collect archaeological data that will, among other things, result in actions that can help preserve this cultural heritage. The first Swedish Antarctic Expedition was led by Otto Nordenskjöld using the vessel Antarctic. Upon reaching the Antarctic Peninsula, the expedition built a hut on the island of … Läs mer…

Field work in the Arctic on the impact of climate on plants and animals

Fredrik Dalerum, Docent in Ecology at the Department of Zoology, Stockholm University, leads a research group that participated in this summer’s expedition with the icebreaker Oden to the Ryder Glacier in northwestern Greenland. In this research project, they study how Arctic species and ecosystems are affected by climate change.

Appreciated polar conference was held in Umeå

This year’s Polarforum was organised at Umeå University and was visited by polar researchers from all over the country. The day included, among other things, presentations by polar researchers and a panel discussion with research financiers. It was the first time that Polarforum was arranged at Umeå University, which was appreciated by Dieter Müller, Professor of Social and Economic Geography and Deputy Vice-chancellor at Umeå University. – It was about … Läs mer…

Melting ice can lead to increased acidification of the Arctic Ocean

The rising temperature in recent years in the Arctic is causing sea ice and glaciers to melt at an ever-faster rate. The melting of the ice sheet in Greenland increases the inflow of meltwater into Greenland’s fjords and coastal water, with physical and geochemical effects on the fjord systems.
