A solid understanding of ecosystem dynamics is essential for effective marine management, especially with the changing environment and increasing anthropogenic pressures, such as fishing. To meet this demand, reliable monitoring data and ecosystem models (for example, coupled hydrodynamic-biogeochemical models, biotic community models, and end-to end models) are increasingly required to assess ecosystem processes and provide guidance to environmental and fisheries managers. The model development requires the understanding of significant process and the inclusion of large quantities of data, and span multiple spatiotemporal scales and levels of complexity. However, the linkage is usually loose among the pivotal components of observing, modelling and assessing. In particular there is often a mis-match in scale between the observational data which is collected on hydrodynamics, biogeochemistry or ecology, versus the scale at which ecosystem models operate. In this symposium, we will discuss the recent methodological development of ecosystem monitoring, assessing and modelling. This symposium aims to bring different types of scientific approaches together to learn from each other’s methods and discuss on a closed-loop approach. A panel discussion at the end of the symposium will help consolidate differences, similarities and learnings, and define future directions.

Contributions are invited on novel techniques and approaches to understanding estuarine and coastal system dynamics through observational studies as well as modelling and assessing approaches in estuaries, shallow seas and shelf waters (studies within lakes may also be considered for inclusion if knowledge translatable to coastal systems). This includes, but is not limited to, oral presentations or posters detailing innovative application of:

  • Modelling approaches to understand coastal and/or estuarine system dynamic
  • Techniques for evaluating the model complexity against uncertainty
  • Influence of observation data characteristics on the performances of modelling and assessing methods (such as ecological indicator);
  • Practices of using ecosystem models for survey design optimization and assessment methods examination
  • Methods for integrating physical and ecological processes operating at different spatio-temporal scales
  • In-situ measurements of hydrodynamics in coastal or estuarine systems
  • Empirical studies of biogeochemistry e.g. fluxes at the sediment-water interface
  • The use of remote sensing methods to fill in the scales between empirical and modelling approaches
  • Integration, cross-fertilization and development of skills for empirical and modelling techniques
  • Translation of the model results into user-accessible tools to support managers and stakeholders
  • Potential application of the integrated framework in marine protected area (MPA), stock enhancement and artificial reef to inform ecosystem management in a changing environment.
