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.

The completion of the Baltic Earth Assessment Reports (BEARs) marks the termination of the first phase, ten years after the launch of Baltic Earth. The BEARs provide a retrospect of Baltic Earth related research, current knowledge and knowledge gaps, and wrap up Baltic Earth activities.

The conference

After the publication of the Baltic Earth Assessment Reports (BEARs) in 2023, reflecting the Grand Challenges and research themes of Baltic Earth over the past ten years, it is now time to move on and update research challenges, and define new ones. The updated and new research foci will be presented and discussed by scientists, students, managers and other stakeholders. There will be a dedicated young scientist´s event. Conference language is English.

The sessions of this conference reflect the Grand Challenges and topics which are currently being discussed as updated and new in Baltic Earth. As the open discussion is ongoing, the final set of new Grand Challenges will be presented at the conference with the new Science Plan 2024. The contributions submitted were arranged according to the sessions below, which reflect the Baltic Earth research topics.

  • A. 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; modelling approaches to explain observations and project future changes
  • B. Natural hazards and extreme events Observations, analysis and modelling of high impact events in the Baltic Sea region; frequency and strength of storm surges and waves, flooding due to extreme precipitation events or droughts; prediction systems, probabilistic estimates and attribution analyses
  • C. Sea level dynamics, sediment dynamics, coastal processes and impacts on coasts Variability and change of mean and extreme sea level; waves, storm surges, currents, seiches, variations in wind and sea level pressure, river runoff, effects of sea ice, inflows, thermosteric effects, land uplift/subsidence and their effects on sea level/sediment transport/coastal changes; projections of future sea level rise, observed and projected long-term trends and multi-decadal variations
  • D. Human impacts, interactions and management options Interactions between anthropogenic forcings like eutrophication, pollution, fisheries, aquaculture, shipping, offshore installations, hydrographic engineering, coastal management, agricultural and forestry practices and land cover change with natual forcings; analysis and application of coupled Earth system models capturing interactions between atmospheric, marine and land compartments/processes, as well as responses to anthropogenic forcings; regional detection and attribution efforts. How to cope with the various human and evironmental impacts described above and climate change, including geoengineering options.
  • E. Modeling past and future climate changes and teleconnections Recent and projected changes in regional climate variables like temperature, precipitation, etc., as well as impacts on the atmosphere, hydrosphere, oceanography, and biosphere of the Baltic Sea region; recent progress in the understanding of regional climate variability with special focus on coupled effects between sea, atmosphere, land and anthroposphere.
    Identification of critical regions with teleconnections to the Baltic Sea; assessment of potential change of atmospheric mass and energy flow over Europe; assessment of dynamically driven climate variability (e.g. jet stream) with its origin far outside the Baltic Sea and its propagation into the Baltic Sea region
  • F. Small scale processes not yet resolved and their impact on the large scale dynamics and patterns State-of-the-art knowledge of submesoscale dynamics in the Baltic Sea and similar coastal and/or marginal sea environments based upon observations and modelling and the role of submesoscale in multiscale interactions, e.g. energy transfer, mixing, development of stratification, coastal-offshore exchanges, fluxes of substances, including through the air-sea interface, etc.
  • G. Comparing marginal seas worldwide How do climatic, geological and human impacts in different polar, moderate and other marginal seas compare with conditions in the Baltic Sea? Can we establish a systematic scheme (classification), describing cause-effect relations for marginal seas with regard to the human-environment relationship?
  • H. Philosophical aspects of Baltic Sea Earth system research Dichotomous thinking and the need for broader, integrative perspectives; complex systems with multiple drivers; ‚external‘ social dynamics in ‚internal‘ scientific modeling; what is the basis of the public authority of scientific knowledge? What is the knowledge market for the Baltic Sea region? What is the boundary between science and activism?


The Conference Progamme and List of Participants are now available. Please note that changes may still be possible (version as of 2 May 2024).

Infos for Poster Authors

Poster walls are portrait format (upright) and can aqccomodate the A0 format (840 x 1190mm) Posters can be set up as soon as the poster walls are set up (Monday afternoon). Posters will be on display all week (Monday afternoon until Thursday afternoon) in a dedicated poster room.

There are two dedicated poster sessions, including a 1 slide, 1 min "Speed talk" session, when poster authors give a short oral introduction to their posters. Please prepare this in addition to your poster. Poster authors will be notified on which day they are asked to give their 1-slide presentation (Wednesday or Thursday).

Infos for Oral Authors

Regular talks have a total slot of 15min, which includes the discussion time. Hence, we ask presenters to limit their presenttaion to 12 min to allow 3 minutes of questions and answers.

Solicited presentations (those opening a session) have 20 min in total, so that means 17+3.

Keynote talks have 30 minutes.

Please have your presentation ready on a stick by the morning of the presentation day, or during the luchbreak if you present in the afternoon.

The Call for Papers is now terminated

Contributions in accordance with the conference topics, as well as contributions from related programmes, both oral or as poster, are welcome. Invited and contributed papers will be presented in plenary and dedicated poster sessions.

Extended abstracts in English, maximum of two pages, including figures, tables or diagrams, are invited to be submitted by e-mail to the International Baltic Earth Secretariat. Contributions will be arranged into sessions which are based on these topics.

Abstracts must be submitted by e-mail to by 5 February 2024. Please indicate to which topic you would like to have your presentation allocated. An electronic abstract template is available for download below. Please use this template, other formats will not be not accepted.

The Scientific Conference Committee will review the submitted papers, decide on allocation to topic, oral or poster presentation and establish the conference programme.

Authors will be notified by end February 2024, and the programme is expected to be online by mid March 2024. An abstract volume will be distributed at the conference.

Authors will be invited to submit a full paper based on their presentation for a special conference issue in an international scientific journal to be published after the conference.

Jūrmala‘s beach is 33 km long, covered with white quartz sand. Jūrmala‘s reputation as a spa destination began in the late 18th and early 19th centuries when wealthy landowners began the tradition of relaxing at the seaside. The sea breeze, pine aroma, mineral springs, and sandy beach encouraged health spas to develop within the city.

The most distinguishing architectural feature in Jūrmala is the prevalence of wooden houses dating from the 19th and first half of the 20th century. Jūrmala‘s architecture typically falls into classicism, national romanticism, and modern styles. The town has an official list of 414 historical buildings under protection, as well as over 4000 wooden structures, and Dubulti Station is an example of sculptural concrete shell modernist architecture.


By air: Rīga Airport is an international hub which is served by all major airports in the Baltic Sea region and beyond. It is possible to get to Rīga train station and downtown by bus. Bus #22 is the best connction to downtown Rīga and the train station (Rīgas centrālā dzelceļa stacija). The trip is about 35 min. Change there to the train to Jurmala.

By train: There are regular trains from Rīga Central Train Station (Rīgas centrālā dzelceļa stacija) to various locations in Jūrmala. The stop „Majori“ (30 min from Rīga Central) is just a few minutes walk from the Conference Hotel.
