Kick-off meetingNice 10 – 13/06/2008
Overarching question:
To what extent will ocean acidification alter ocean carbonate
chemistry, biogeochemistry, and marine ecosystems over the next
200 years, and how will that feed back on climate change?
Tools:
models: coastal-, basin- to global scale, and Earth system
Appraoches:
model development: pH sensitive process descriptions (link to
theme 2)
assessment of model skills: comparison to data (link to activities of
theme 1); between models
sensitivity studies
model simulations: pre-industrial period + future (C-emission
pathways)
