6th Baltic Earth Conference 2026
Event

- LocationHeringsdorf, Germany
- Time13 - 17 April 2026
- HostInternational Baltic Earth Secretariat at IOW and IOPAN
Background
The Baltic Earth scientific network strives to achieve an improved Earth System understanding of the Baltic Sea region as the basis for science-based management in the face of climatic, environmental and human impact in the region. Baltic Earth brings together a broad international research community around scientific issues relevant for societal efforts to achieve sustainability in the region. Baltic Earth targets the atmosphere, land and marine environment of the Baltic Sea, its drainage basin and nearby areas with relevance for the Baltic Sea region. Baltic Earth has entered a new phase, called Baltic Earth 2.0. It is characterized by a new secretariat shared between Germany and Poland and revised research topics, which will be the foci of the conference.

Climate variability and teleconnections
The session examines how climate variability and teleconnections shape weather and climate across Northern Europe and the Baltic Sea region. We invite contributions that for example link the North Atlantic to the Baltic - from jet stream dynamics and storm track variability to ocean-atmosphere coupling to the North Atlantic Oscillation and other features of the climate system. We particularly welcome studies that focus on how these drivers project onto the seasonally varying background state, separate multiple time scales and address how they influence extremes, regional climate variability and their predictability.Submissions may use reanalyses (including century-scale products), CMIP/RCM ensembles and downscaling, forecast systems, process-based diagnostics, causal/attribution frameworks, and storyline or event-based approaches. Case studies that integrate observations and modelling, assess model skill for the Baltic domain, or connect teleconnections to impacts and services are encouraged.
Microscale to basin-wide oceanographic processes and their impacts on the large-scale circulation
The presence and role of mesoscale eddies, converting the potential energy of sloping isopycnals into kinetic energy and transferring energy from large to smaller scales, have been recognized for a long time. However, the pathways for energy transfer from mesoscale to smaller scales and eventually dissipation have yet to be clarified. Furthermore, the impact of small-scale processes from micro- to mesoscales on the basin-wide circulation and its internal variability and predictability is still not well known. In this session, studies based upon both modelling and analysing observations, addressing oceanographic processes on various temporal and spatial scales, are welcome.
Natural hazards and their impacts
The Baltic Sea region is one of the most populated and industrialized in Europe, making it highly vulnerable to natural hazards. This session addresses the causes and impacts of extreme hydro-meteorological, marine, and geological events in the region. We welcome contributions on forecasting and early warning, attribution to climate change, compound impacts on society, coasts, and ecosystems, as well as strategies for risk reduction and resilience building.
Sea level and coastal change
Coastal change in the Baltic Sea is the result of wind, air pressure and sea level variations, waves, land uplift/subsidence as well as other coastal drivers mobilizing and transporting sediments. It is most obvious during storms, sometimes in concert with coastal flooding, when the sea level is elevated, the combined result of higher water levels that are driven by the dynamics of the North Sea, and processes driven by regional and local weather conditions against the backdrop of mean sea level rise. Studies on sea level variability, waves, land uplift as well as subsidence and their effects on sediment transport and coastal changes are welcome.
Biogeochemistry of the Baltic Sea – Linking observations and modelling
Investigations on the marine and terrestrial carbon, nitrogen and phosphorus cycles and pathways towards an understanding of primary production mechanisms and organic
matter transformations in the Baltic Sea; biogeochemical causes and effects of eutrophication, oxygen limitations and trace gas production, including microbiological processes; and modelling approaches to explain observations and project future changes are welcome.
Adaptive governance under multiple drivers of change in the Baltic Sea
The Baltic Sea and its catchment area is influenced by multiple interacting physical and socioeconomic drivers, including climate change, nutrient loading, economic development, demographic change, and technological innovation, among many others. These overlapping pressures create high uncertainty, making it difficult for governance systems to anticipate future conditions or to design and implement effective, long-term solutions. Modelling frameworks can play a critical role in adaptive management: creating different scenarios, exploring system dynamics, and participatory modelling approaches allow stakeholders to explore uncertainty, test alternative mitigation and adaptation strategies, and update management responses as conditions evolve.These approaches are increasingly being recognized as essential for managing under uncertainty and complexity. Yet their application in the Baltic context has been uneven, and lessons remain scattered. This session will explore how adaptive and model-informed approaches can help address the cumulative and interacting nature of multiple drivers, and how governance systems can build resilience in the face of change and uncertainty.
Marginal Seas – Humans and Environment
The Baltic Sea is one of the best-studied regional seas, and the research community possesses extensive paleo-environmental, prehistoric, and historical data. As a semi-enclosed sea bordering the open ocean, the Baltic Sea, like other comparable seas, is increasingly threatened by changing natural and anthropogenic impacts. This global pressure on marginal seas, their coasts, and their catchment areas is caused in particular by climate change and the overexploitation of their resources. The corresponding call for generally applicable sustainable management strategies and concepts has led to the integration of special scientific sessions into the program of the biennial Baltic Earth Conferences since 2022, focusing on the global comparison of the Baltic Sea with other marginal seas. We are continuing this initiative and invite marine geoscientists, life scientists, economists, historians, and stakeholders from around the world to the 2026 conference in Heringsdorf to exchange experiences and concepts for the sustainable management of marginal seas and to discuss them jointly to approach the UN Sustainable Development Goals.
Future projections of the Baltic Sea region
The Baltic Sea region is strongly impacted by anthropogenic climate change and ranks among the fastest warming seas globally. Continued warming is expected to lead to changes in temperature, salinity, and nutrient dynamics—affecting marine ecosystems and the services they provide to human society. Consequently, robust climate projections are essential for effective adaptation and planning. While global climate projections from the Climate Model Intercomparison Project (CMIP) are available, their spatial resolution is too coarse to adequately capture the complex characteristics of the Baltic Sea region, including its orography, land-sea distribution, and key regional processes. Moreover, many models struggle to accurately represent observed natural climate variability. This session welcomes contributions focusing on future climate projections for the Baltic Sea region, addressing the aforementioned challenges and strategies to overcome them.
Philosophical aspects of Baltic Sea Earth system research
During this session, we will explore and discuss the big ideas behind Earth System Science on a regional scale, such as the Baltic Basin or other marginal seas. The Earth System Science analyzes how physical, chemical, biological, and human processes interact. Understanding the Earth System in the Baltic Basin has been shaped by several key ideas that have been developed over the years, including, e.g., land uplift and glaciation, estuarine circulation, climate change and variability, acidification, eutrophication, fishing success, and human impacts. We invite presentations that address the initiation of one or more of these ideas, their progress, and their significance for understanding Earth System Science.
The dedicated call for papers will be released in October 2025 and will include detailed descriptions of the scientific sessions. Submissions are welcome on any of the topics listed above, as well as on related themes and programmes.
Both invited and contributed papers will be presented in plenary sessions and dedicated poster sessions. A special event will also be organised for early-career scientists.
