Environmental monitoring and risk assessment


 Integration of environmental monitoring with risk assessment

IRIS Environment has for several years been involved in the development of tools for environmental assessment of offshore discharges. These tools include environmental predictions through risk models (‘DREAM’) as well as environmental effect monitoring through ‘biomarkers’ measured in exposed living organisms. Both have become ‘North Sea standard’ methods that all operators on the Norwegian Continental Shelf now use.
A shortcoming has been the  lack of integration of these prediction and monitoring tools. Being involved in the development of both of these aspects, IRIS Environment has been able to bridge this gap, by  constructing so-called ‘biomarker bridges’  in order to establish a more ‘integrated management system’ for offshore discharges. The results of this extensive effort have now been published in a ‘trilogy’ of scientific articles that in turn cover the experimental generation of data, the links between monitoring and risk parameters, and the interpretation of biomonitoring data within the environmental risk management scheme the oil industry currently uses in the North Sea.
The method will be applied for the first time in the ‘Water Column Monitoring’ survey planned for 2017, which will be led by IRIS with the Norwegian Institute of Water Research, the Institute of Marine Research and SINTEF as partners.
