Theme 2 - Implementation
Organism responses
Community level responses
WP6 Performance: reproduction and growth
Experiments on key organisms:
copepods, bivalves, bioturbators,
squid & fish
Sensitivity of early life stages
Acid-base regulation  changes in gene
expression
CO2 effects on temp. tolerance 
latitudinal cline adaptation potential

Organism responses
Community level responses
WP9 From process studies to ecosystem models
Process oriented meta-analysis of
experimental results
Modeling of mesocosm experiments,
including data-assimilative parameter
estimation
Meta-analysis of model structures and
parameterizations
Models improvement for optimal balance
between model complexity, performance
and portability
Parameterization assessment 
recommendations for incorporation into
global-scale models
