Baltic Sea Dynamics through 4D Modelling and Integrated Earth Observation (4DBALTDYN)

The 4DBALTDYN ESA project is at the forefront of advancing our understanding of the Baltic Sea's dynamics by integrating state-of-the-art technologies. While modern satellite data excels in global monitoring, its focus on surface phenomena limits our holistic view of the marine environment. Although numerical modeling is a crucial tool, challenges persist in replicating complex environmental interactions. Acknowledging this, the project adopts a complementary approach, combining numerical modeling, AI, ML, and Earth Observation data for a comprehensive Baltic Sea overview. Specialized products, analyzing biochemical exchanges, and employing Earth Observation and modeling contribute to a 4D reconstruction in 2016-2023. Addressing the inadequacy of traditional methods, the project covers key variables like ocean color, sea surface temperature, open ocean, coastal sea level, and salinity. By characterizing surface circulation patterns and integrating AI models, the project aims to transcend limitations and make significant contributions to marine research. Interdisciplinary Science Case Studies address key questions and knowledge gaps, emphasizing a holistic approach. The project envisions a robust 4D reconstruction of Baltic waters, enhancing insights into physical and biogeochemical parameters through the integration of EO data, models, and AI. As the project commenced in April 2024, this presentation provides an overview, outlining aims, structure, developed products, validation processes and case studies outline.
