Description
The project addresses potential effects of produced water on
the copepod Calanus finmarchicus, which has a key
role in transferring energy from primary production to
higher trophic levels in the North Atlantic and Barents
Sea. Based on dynamic energy budget (DEB) theory, a
modified DEB model for C. finmarchicus will be
developed. Data on uptake and elimination of selected
produced-water components and molecular changes in the
copepods will be used to make a toxicokinetic model that
will be linked to the DEB model. The aim of the work is to
provide effect limits for potential long-term population
effects of produced water that can be used in risk and
impact modelling, and relate these data to molecular changes
that can be used in environmental monitoring. The outcome of
the project will thus benefit both the management and the
industry in securing that the risk of environmental impacts
from offshore petroleum activities are kept to a minimum.
My role
Developing a DEBkiss
model for copepods, in particular Calanus
finmarchicus. Advising on the most efficient
experimental design, and analysing the results from the
experimental testing on toxic effects and toxicokinetics.
