Advancing Marine Ecosystem Modeling for a Predictable and Sustainable Ocean
Session ID#: 257543
Session Description:
Marine ecosystems are essential for human well-being but face increasing threats from climate change and human activities. Sustainable ocean practices, guided by robust understanding and predictive tools, are vital to address these challenges. Marine ecosystem models play a key role by simulating ocean biogeochemistry, ecosystem processes, and responses to environmental stressors, supporting effective management and sustainability efforts.
These models range from simple parameterizations to complex, fully coupled systems that integrate ocean physics, biogeochemistry, and ecology. Their applications include historical reconstructions, near-term forecasts, climate projections, and scenario simulations.
Advancements in marine ecosystem modeling are fuelled by expanding ocean observations, greater computational capacity, and improved data assimilation. This session highlights innovations in modeling to enhance analysis, prediction, and decision-making. We welcome contributions that:
- Integrate novel data (e.g., Argo floats, genomic surveys);
- Use advanced tools (e.g., AI, digital twins);
- Link lower and higher trophic levels (e.g., zooplankton and fishes);
- Predict and mitigate ocean threats (e.g., algal blooms, acidification);
- Improve understanding of nutrient cycling and trophic dynamics.
Co-organized by OceanPredict’s Marine Ecosystem Analysis and Prediction Task Team and the EU NECCTON project, this session fosters interdisciplinary collaboration to advance marine ecosystem science and sustainability
