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.
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.
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.
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.
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.
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.
Weather balloons and meteorological measurements are in focus when Sonja Murto, PhD student at Stockholm University, participates in the research expedition Synoptic Arctic Survey.
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.
