4th Baltic Earth Conference

Assessing the Baltic Sea Earth System

  • LocationJastarnia, Hel Peninsula, Poland

That was the 4th Baltic Earth Conference in Jastarnia! Thank you to everybody who made this a successful and pleasant experience!

From 30 May to 3 June, we had our 4th Baltic Earth Conference at the Hotel Dom Zdrojowy in Jastarnia, Poland. We had intensive and fruitful scientific discussions with new plans for the Baltic Earth network, which will be elaborated in the next two years and will cumulate in an updated Baltic Earth Science Plan.

Baltic Earth conferences are scientific events, but they are also places for making new connections or updating old ones. Here, lifelong friendships and collaborations between scientists from different countries and scientific disciplines are built and strengthened.

We are happy that more than one third of our participants are young scientists, who carry on the torch with new people and ideas.

The completion of the Baltic Earth Assessment Reports (BEAR) marks the termination of the first phase, nine 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 nine years of Baltic Earth activities.

The conference covered the topics of the Baltic Earth Assessment Reports (BEAR), which reflect the majority of Grand Challenges and research themes of Baltic Earth over the past nine years.

Conference participants presented their research around these topics and discussed both Baltic Earth achievements and the way forward. The conference wasintended as discussion forum for scientists, students, managers and other stakeholders. There was also a dedicated young scientist´s event.

The sessions of this conference reflect the topics of the Baltic Earth Assessment Reports and other Baltic Earth topics. In discussing the different topics, we would like to include the perspectives from other marginal seas (like the neighboring North Sea, but also around the world). Contributions from other marginal seas shall help to evaluate the state of the regional Earth system (including human impacts) and management options in the Baltic Sea and elsewhere.

  • Salinity dynamics Improved understanding of atmospheric patterns in various space and time scales including precipitation forcing water exchange with the North Sea, between sub-basins, estuaries and lagoons, and impacting on internal circulation, meso-scale dynamics and turbulence. Salinity stratification and its role in increasing areas of hypoxia. Environmental interaction between fish, its reproduction and varying salinity conditions on different time scales in the Baltic Sea.
  • Biogeochemical functioning and development: From catchment to the open sea 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.
  • 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.
  • Sea level dynamics and coastal erosion 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.
  • Regional variability of water and energy exchanges Observation, analysis and modelling of the regional water cycle; precipitation, evaporation, river runoff; hydrological and atmospheric exchange processes; analysis of the natural variability of energy and water components; cloud-aerosol-feedback mechanisms, cloud and atmospheric boundary layer processes; hind- and forecast short- and long-term water and energy exchanges of the past and future
  • Human impacts and their interactions 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
  • Sustainable management options to cope with the various human and evironmental impacts described above and climate change, including geoengineering options
  • Analysing and modeling past and future climate changes Recent and projected changes in regional climate variables like tenmperature, 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
  • Comparing marginal seas How do climatic, geological and human impacts in different polar, moderate and other marginal seas compare with conditions in the Baltic Sea?
    This session is organized in cooperation with the Marginal Seas Task Group, Deep-time Digital Earth (DDE), IUGS Big Science Program.

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 mid-February 2020, and the programme is expected to be online by the end of February 2022. The abstract volume will be available electronically prior to 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.

The Hel peninsula

The Polish Baltic Sea coast is approximately 528 kilometres (328 mi) long and extends from Świnoujście on the islands of Usedom and Wolin in the west to Krynica Morska on the Vistula Spit in the east. For the most part, Poland has a smooth coastline, which has been shaped by the continual movement of sand by currents and winds. This continual erosion and deposition has formed cliffs, dunes, and spits, many of which have migrated landwards to close off former lagoons, such as Łebsko Lake in Słowiński National Park.

Hel peninsula is a narrow sandy spit, separating the Bay of Puck, the western part of Gdansk Bay, from the Baltic Sea. It is a part of the Puck County of the Pomeranian Voivodeship, and located close to the metropolitan area of the Tricity: Gdynia, Sopot and Gdansk, with more than 1 million inhabitants, for many of which it serves as a recreational refuge.

The Conference Venue

The conference takes place in the Hotel Dom Zdrojowy in Jastarnia in Puck County, Pomeranian Voivodship, Poland, located on the Hel Peninsula. Hel Peninsula with its two main towns Jastarnia and Hel is a holiday resort for the greater Gdynia-Sopot-Gdansk (Tri-City) metropolitan region.
