WP3: Ecosystem response to climate scale drivers

This WP considers two classes of experiments using coupled coupled physical-biogeochemical-HTL models: re-analysis forced simulations and climate-scenario forced simulations The objective of the former is to hindcast recent history using forcing constrained by observations (such as ERA-40 and NCEP). This provides reference simulations which can be verified against contemporary observations to give estimates of uncertainty in the models and feedback to development/parameter choice (WP2).

Objectives
To define the envelope of response to climate and circulation drivers of marine ecosystem function both on a global and a regional scale. We shall analyze the impact on ecosystems end to end of changes in temperature, circulation, mixing, acidification, and light, focusing on physics, biogeochemistry and ecosystem productivity (task 3.3), and on higher trophic levels (task 3.4). The sub objectives are

To define common metrics and scenarios
To run/analyze base-line and ensemble scenarios
To synthesize results
To contribute to knowledge transfer activities in WP6
To publish advances in technical and scientific knowledge
