SWEDISH SOCIETY FOR MARINE SCIENCES

Marine Research Days 2025

Promoting marine research between disciplines and stakeholders

Date: November 18 - 20, 2025

Venue: Wallenberg Center, Gothenburg

The Swedish Society for Marine Sciences welcomes everyone who is engaged and interested in marine sciences, management and environmental monitoring to this conference on the SEA ! The meeting focuses on current aspects of research, management, and environmental monitoring in marine systems. In addition to oral presentations and a poster session, there will be room for networking.

ProgramThe program will be shown here after October 31

Ocean Recovery Through Collaboration: Lessons from the Stickleback Wave

Reversing ecosystem degradation requires bridging scientific insight and societal action. In the Baltic Sea, the decline of large predatory fish such as pike and perch and the rapid rise of the three-spined stickleback illustrate how ecological feedbacks and governance challenges interact across scales. Through the interdisciplinary FORCE project (Facilitating Ocean Recovery in a Changing climatE), we integrate ecology, law, and social science to identify social-ecological drivers of change and explore practical pathways for recovery. Our work emphasizes reconciling top-predator conservation with ecosystem-based management and making fuller use of legal and institutional frameworks to foster collaborative marine stewardship. I will also present preliminary results from a large-scale field study displaying how fishery closures influence the recovery of predatory fish and their cascading effects in coastal food webs. Together, these insights show how cross-disciplinary collaboration can transform understanding into effective action for ocean recovery.

Titel: When the Ice Last Melted: Paleo Perspectives on Arctic Sea Ice in a Warmer World

The geologic history of Arctic sea ice is a critical, but missing piece in the narrative on global climate change. Arctic marine sediments preserve a long-term archive of sea ice variability offering a rare window into cryosphere dynamics well beyond the limits of the instrumental record. These paleo-records enable us to explore the complex links between Arctic and global climate systems and to test the models we use for future sea ice projections. However, the development of the Arctic’s perennial sea-ice cover, and its persistence across Quaternary (last 2.6 million years) interglacial periods, remains a subject of active debate. Early paradigms that suggested a persistent perennial sea ice cover since the middle Miocene (12 -14 million years ago) appear incompatible with terrestrial paleoclimate data and marine proxy evidence suggesting profoundly different oceanographic and sea ice conditions in the recent past. Continued methodological advances in paleo-sea ice reconstructions, using microfossils, biogeochemical proxies, and ancient DNA, are revolutionizing our ability to track sea ice variability. Recent (GEOEO 2024, AO25) and planned expeditions (AO26, AO27) on Sweden’s Icebreaker Oden are providing access to regions of the Arctic where the thickest multi-year sea ice exists today, and is projected to persist longest in the future. This talk will outline current ideas on sea ice variability during the early Holocene and previous Quaternary interglacials and discuss how multi-proxy approaches from these new expeditions are poised to resolve long-standing questions about the resilience and variability of Arctic sea ice in a warmer world.

Abstract submission opens September 24 and closes October 24

Abstract submissions for oral or poster presentations are highly recommended and encouraged. Submission is managed through the registration portal below. Submitted contributions will be organized within sessions based on the conference program, or standalone if the content is considered outside the scope of the sessions provided (see program outlined below). Depending on the number of submitted abstracts (oral and posters), the Board may need to prioritize. Submissions from second (MSc) and third (PhD) cycle students, as well as from early career scientists (post docs), will be given priority.

The Dyrssen Award

Svenska Havsforskningsföreningen delar årligen ut Dyrssenpriset för de två bästa examensarbetena i marinvetenskap på master­nivå. Förstapriset är 10 000 SEK och andrapriset 5 000 SEK. Priset har instiftats av SHF till minne av David Dyrssen (1922–2011), emeritusprofessor i analytisk kemi vid Göteborgs universitet. Som en av föreningens grundare ägnade han sin karriär åt att aktivt främja tvärvetenskaplig forskning inom marinvetenskap. Prisutdelningen äger rum den 19 november.

Annual meeting

The Swedish Society for Marine Sciences is an independent non-profit organisation. The society holds its annual meeting on 19 november 2025 at 15:00 as part of the conference. Please note that the annual meeting will be held in Swedish. For more information see the document under the sub-menu About us in the main menu
