Objectives: (see full WP description - restricted access)

The overall objective of this WP is to quantify the key processes controlling the flow of carbon and energy, within and between trophic levels in the North Atlantic and shelf ecosystems.

Specific objectives are:

1. To quantify the role of key species and functional groups in the rate of transfer of biomass and carbon within the marine food web.

2. To evaluate the relative importance and interactions of top down versus bottom up controls on community structure and carbon sequestration.

3. Provide field and experimental data for understanding the physiological range of key ecological species i.e. vital rates

4. To quantify vital rates and potential competitive interactions between co-existing species

5. To develop rate parameterizations and and provide data for validation of the integrated models produced in WP6 Basin-scale Integrative Modelling.

6. Develop indices of key species and ecosystem status for use in WP8 Advancing Ocean Management.
