Interviews for Synoptic Arctic Survey 2021
23 Sep 2022 Viruses that hitchhike or kill
In the oceans, there are viruses that infect bacteria. Even though they have a major impact on our ecosystems, the research in this area is limited, especially from Arctic environments. Researchers who participated in the Synoptic Arctic Survey 2021 expedition are currently studying this. They want to understand how environmental pollution and climate change affect viruses, bacteria, and ecosystems in the future.
13 Sep 2022 From sea to cloud – what happens in the Arctic atmosphere?
To explain the reasons for the rapid warming in the Arctic, measurements of the atmosphere are needed. On the icebreaker Oden, researchers within the ACAS project have developed an atmospheric observatory to be able to study factors such as changes in clouds and the interactions between the surface and the atmosphere.
30 Aug 2022 Microorganism shell acts as a time capsule
At the bottom of the Arctic Ocean, empty shells from dead foraminifera, microscopic single-celled organisms, accumulate. The calcium carbonate shells can be compared to time capsules because the million-year-old fossils can provide valuable information about climate change. During the Synoptic Arctic Survey 2021 expedition with the icebreaker Oden, one of the projects was about documenting these organisms.
23 May 2022 Ocean acidification damages the marine ecosystem
Adam Ulfsbo is a researcher at the Department of Marine Sciences at the University of Gothenburg and was one of the participants in the research expedition Synoptic Arctic Survey 2021 with the icebreaker Oden. There he investigated processes and factors behind changes in carbon storage and ocean acidification.
11 Mar 2022 Bacterial respiration and abundance affect life in the Arctic Ocean
What is the abundance, diversity, growth rate and respiration of Bacteria and Archea in the Arctic Ocean ecosystem? This is the question Johan Wikner, Professor in Ecology at Umeå University, and his team studied during the Synoptic Arctic Survey 2021 expedition with the icebreaker Oden.
23 Jun 2021 Small Arctic organisms of great importance for life on Earth
Bacteria, and other small organisms without a cell nucleus, create conditions for life on our planet and assume art-like forms. This is something that fascinates Johan Wikner, professor of ecology at Umeå University, who is now preparing for the research expedition Synoptic Arctic Survey with the icebreaker Oden.
09 Jun 2021 "We want to get an overall picture of the state of the Arctic"
This summer's polar expedition with the icebreaker Oden constitutes the Swedish contribution within the international research initiative Synoptic Arctic Survey, SAS. One of the researchers participating is Adam Ulfsbo at the University of Gothenburg and he is really looking forward to the expedition.
07 Jun 2021 "I hope to learn a lot from the researchers"
Anna Stiby, chemistry and biology teacher, was selected to participate in the Swedish Polar Research Secretariat's teacher program 2021. Now she has an intensive work period at Nacka gymnasium, but soon it's time to change the classroom to the icebreaker Oden and this summer's expedition to the Arctic Ocean.
03 Jun 2021 Plankton reveal how global warming is affecting the Arctic ecosystem
Hanna Farnelid, associate professor in marine ecology at Linnaeus University in Kalmar, is one of the researchers participating in this summer's Arctic expedition with the icebreaker Oden. This is her second expedition with Oden, the last time it happened was in 2007 when she participated in the expedition Oden Southern Ocean to Antarctica.
10 May 2021 Leads expedition to the Arctic Ocean with icebreaker Oden
“Hypothesis is a great word that has so much in it. A researcher's task is to develop a question, formulate a hypothesis and then test whether it is true or false. It is the most glorious word in science”, says Pauline Snoeijs Leijonmalm, Professor of Marine Ecology at Stockholm University. Soon she will go on her fourth research expedition with the icebreaker Oden, where she will have the role of Chief Scientist.
