An oceanic sill influences melting of one of Greenland’s glaciers

Greenland’s melting ice sheet has in recent years contributed with about 26 percent to the global sea-level rise according to published calculations, but how different glaciers are affected by climate change differs. Research from the Ryder Expedition with the icebreaker Oden in 2019, shows that a relatively shallow formation in the seabed in front of one of North Greenland’s largest glaciers, reduces the amount of warmer Atlantic waters that reach … Läs mer…

Research on fish and microbes in the Central Arctic Ocean

Pauline Snoeijs Leijonmalm, Professor of Marine Ecology at Stockholm University, participated in the first leg of five during the polar expedition MOSAiC. A strong memory is when the German research icebreaker RV Polarstern anchored to an ice floe to drift with the pack ice in the Arctic Ocean for a year. – I will never forget the fascinating, alternating noisy and whistling sounds, caused by pressure when a ship freezes … Läs mer…

New research: iodic acid affects cloud formation in the Arctic

In 2018, the research expedition Arctic Ocean was carried out with the icebreaker Oden. One of the goals of the research on board was to understand how clouds form in the Arctic. With the help of data collected during the expedition, researchers at Stockholm University and the Swiss EPFL, among others, have now published an article in Nature Communications. The formation of clouds is one of several factors that may … Läs mer…

Polar research a priority area in the Swedish Government’s Arctic strategy

The government recently published Sweden’s strategy for the Arctic region. As one of the eight Arctic states, the government wants to strengthen Sweden’s involvement and contribute to peaceful and sustainable development in the Arctic. One of the priorities in the Arctic strategy is for Sweden to have a leading position in polar research. – Research in the Arctic is becoming increasingly important for understanding climate change and its consequences. It … Läs mer…

Public procurement of CTD winch for icebreaker Oden

The Swedish Polar Research Secretariat (SPRS) intends to invest in a multipurpose CTD winch system to be installed at icebreaker Oden. The scope of the procurement includes construction and commissioning of the CTD winch and an associated container in which the winch shall be placed. A CTD is an oceanography instrument used to measure the conductivity, temperature, and pressure of seawater (the D stands for “depth,” which is closely related … Läs mer…

Call for thematic proposals within the Polar Research Process

The call for research themes is the first step in the Polar Research Process (PRP). The intention is to give researchers a possibility to propose a thematic area for upcoming expeditions. Successful proposals will be further processed into finalised expedition themes together with other researchers and the Swedish Polar Research Secretariat (SPRS). A successful theme needs to include research questions from different disciplines and be able to lead to a … Läs mer…

“The course was good preparation for my fieldwork in Alaska”

Charlotte Fredriksson works as a PhD student at the Department of Geological Sciences at Stockholm University. To prepare for field studies in Alaska, she went to the Abisko Scientific Research Station and attended a field course given by the Swedish Polar Research Secretariat. How can the field course help you in your future fieldwork? – Since this is the first time I’m going to fieldwork, and also in a place … Läs mer…
