Marine Ecosystem Connections: carbon and nitrogen fluxes through the benthic and pelagic domains. - ME3205

Summary Objectives.
The main objective of this research is to determine key ecosystem connections that are susceptible to change by acquiring an understanding of the key flows of carbon and nitrogen between marine ecosystem components and how changes in environmental conditions, or human perturbations, may impact upon these.

Key Customer Purpose.
Results of this research will be used to advise Defra on all aspects of ecological indicator (Ecological Quality Objectives, EcoQOs) selection for the marine environment, in support of the Ecosystem Approach to Environmental Management and commitments to OSPAR and the 5th North Sea Conference.
Valuable advice on the undesirable consequences of nutrient enrichment, and the development of indicators for assessing these consequences will also be derived from the research.
