Advancing global ecological modelling capabilities to simulate future trajectories of change in marine ecosystems

Considerable effort is being deployed to predict the impacts of climate change and anthropogenic activities on the ocean to better understand how marine ecosystems are changing and explore alternative pathways and options. This study presents an updated version of EcoOcean (v2), a spatial-temporal ecosystem modeling complex of the global ocean that spans food-web dynamics from primary producers to top predators. We use the updated platform to simulate past and future scenarios of change, and quantify the impacts of alternative model configurations, responses to climate-change scenarios, and the additional impacts of fishing. EcoOcean v2 can contribute to the quantification of cumulative impact assessments of multiple stressors and of plausible ocean-based solutions to prevent, mitigate, and adapt to global change.
