Monitoring Marine Environmental Quality

• Validates our risk assessments - feedback loop

• Integrates effort from a number of Departments and Agencies to meet Defra needs to demonstrate sustainable development

• Potentially provides clear measures of our performance in managing marine systems.

International Obligations - OSPAR

Hazardous Substances

“by continuously reducing discharges, emissions and losses of hazardous substances with the ultimate aim of achieving concentrations .....near

background values for naturally occurring substances and close to zero for man-

made synthetic substances”

International Obligations - OSPAR

Eutrophication

“to achieve and maintain a healthy marine environment where eutrophication does

not occur”

International Obligations - OSPARBiodiversity

“to protect and conserve the ecosystems and the biological diversity of the maritime area

which are, or could be, affected as a result of human activities, and to restore, where

practicable, marine areas which have been adversely affected.”
