Summary:
A new international research project will strengthen observations across the Southern Ocean and Antarctica as scientists seek to understand rapid changes in sea ice, ocean circulation, ice shelves and ecosystems. The EU-funded SYNCHRONY project, launched on 1 August 2026, brings together 27 partner institutions under the coordination of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI).
Over four years, researchers will connect and expand existing observation networks, coordinate measurements across multiple platforms and improve access to polar data. The project will also develop products that provide a clearer picture of climate conditions and biodiversity across a region that remains difficult to monitor.
SYNCHRONY will support Antarctica InSync, a UN Ocean Decade initiative planning extensive polar observations between 2027 and 2029. AWI will contribute research cruises aboard Polarstern, autonomous instruments and the HAFOS observatory in the Weddell Sea. With around €8.5 million in EU funding, the project aims to improve climate and ecosystem predictions while providing evidence for decisions on Southern Ocean protection.

A new observing system for the Southern Ocean
The EU project SYNCHRONY launched on August 1st, 2026. It aims to contribute to a better understanding of the rapid changes taking place in the complex system comprising the ocean, ice and atmosphere in the Southern Ocean and around the Antarctic ice shelves, as well as their impacts on the global climate and biodiversity. Led by the Alfred Wegener Institute, researchers from a total of 27 global partner institutions from around the world will work in interdisciplinary work packages to optimise and expand the existing observing system, harmonise data streams, and create new data products that document the state of the climate system and biodiversity. The project thus also provides an important foundation for the international UN Ocean Decade initiative Antarctica InSync and builds on existing research consortia.
The EU will fund SYNCHRONY with around 8.5 million euros over the next four years.
The Southern Ocean and the Antarctic shelf seas have been undergoing massive changes for several years. Sea ice cover, for example, is declining dramatically, large parts of the West Antarctic ice sheet are being lost, and deep-water formation appears to be declining.
“The full implications of these abrupt changes for the local and global climate and the ecosystems remain unclear. We are currently unable to predict these changes,” explains SYNCHRONY principal investigator Prof. Dr. Alexander Haumann, who heads the AWI-LMU Joint Research Group for Southern Ocean–Climate Interactions (SO-CLIM) at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) and holds a professorship at Ludwig-Maximilians-Universität Munich (LMU).
The oceanographer adds: “This knowledge gap is largely due to insufficient observational data and the inaccurate or missing representation of processes in Earth system models. Urgent action and enhanced international cooperation are therefore required not only to better observe and understand the complex changes in the coupled ocean-ice-atmosphere-biosphere system, but also to provide the basis for polictical decision-making that will protect this region in the long term.”
Joint cross-platform missions and circumpolar, multidisciplinary observation networks are indispensable for this effort in this vast and inaccessible region – yet they are still not available to a sufficient extent. Major international initiatives in the coming years will be key building blocks in closing this observational gap: Antarctica InSync (2027 to 2030), the 5th International Polar Year 2032/2033, and the implementation of the European Ocean Pact. They build on the existing efforts of networks such as SCAR (Scientific Committee on Antarctic Research) and SOOS (Southern Ocean Observing System).
SYNCHRONY will now be another crucial building block. The project aims to establish an internationally coordinated and synchronised observing system in the Southern Ocean and the coastal regions of Antarctica. It coordinates interdisciplinary activities that specifically contribute to Antarctica InSync.
The Antarctica InSync initiative was launched by several members of the Antarctic Treaty System. It forms part of the UN Ocean Decade and supports the UN 2030 Agenda, in particular Sustainable Development Goals (SDGs) 13 and 14, which focus on measures to combat climate change and its impacts, as well as the conservation and sustainable use of the oceans, seas and marine resources. Between 2027 and 2029, Antarctica InSync will establish one of the largest observing networks ever set up in polar environments to assess the state of this rapidly changing environment and promote sustainable development.

“SYNCHRONY will expand and improve Antarctic observing networks, consolidate existing datasets, collect new ones and make them more accessible to the international research community. It will mark a milestone towards a comprehensive polar observing system. The resulting knowledge will help us to better understand the rapid changes in the region and make them more predictable,” says Prof. Dr. Stefanie Arndt, head of the AWI–University of Hamburg Joint Research Group on snow research on Antarctic sea ice (SNOWflAke) and co-principal investigator for the project. “This action-oriented knowledge will also form an important basis for policy decisions on the protection of the climate and biodiversity in the Southern Ocean and will support international intergovernmental bodies, the European Green Deal and the European Ocean Pact.”
The Alfred Wegener Institute (AWI) is coordinating the international research project SYNCHRONY. With five planned Polarstern cruise legs during the main observation period of Antarctica InSync (Antarctic summer 2027/28 to summer 2028/29), autonomous instruments, and the multidisciplinary HAFOS observatory in the Weddell Sea, the AWI is contributing key research infrastructure. Furthermore, it is taking on a leading role in establishing a dedicated observation network for sea ice, atmospheric, ecosystem and ocean research, in the harmonisation of polar research data, and in international coordination and science communication.
