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.

Blog: “Back in Petermann Fjord”

September 2, 2019, the Ryder expedition. We have left the far north. We are now working a bit south of the north; we are back in Petermann Fjord. All the time in Ryder we always said – everything is better in Petermann. 2015 we did Petermann. Over 6 000 km of mapping. It felt like we cored sediment samples to the centre of the earth. Now we are back for more. … Läs mer…
