CLS is developing an ocean ecosystem model to investigate population dynamics of exploited and protected species, through international collaboration with fisheries scientists, marine biologists and oceanographers.
This model will contribute to a better understanding of how marine ecosystems function, with a focus on understanding the influence of both human activities and climate-environmental variability. It will also be a useful tool for ecosystem-based management and sustainable exploitation of marine resources.
Here is our strategy:
Developing models for marine resources management |
| |
MEMMS uses a model to simulate the pelagic ecosystem. This model allows us to analyze the status of exploited/protected marine species. This model can be coupled to any three-dimensional model simulating ocean physics and biogeochemistry. Based on simulated or specified primary production, the model describes several trophic components:
- prey (one or several functional groups)
- predators (one or several species)
The model also includes a description of multiple fisheries. It integrates the effects of fishing and environment.

Controling the quality of our models via technical developments
|
| |
To ensure the quality of our model, we are continually introducing new technical developments, designed to provide best estimates based on existing observations.
We continually work to optimize:
- model formulation and parameterization
- data assimilation techniques
- numerical solution methods
|
Increasing the models' scope: from global to regional systems
|
| |
The model is currently used to investigate the impacts of climate change on marine species on a global scale. In parallel, we plan to increase spatial resolution to include realistic regional meso-scale features, which will be the basis of new products for analyzing individual behaviors and population habitats.

Our models allow scientists to study pelagic species dynamics.
