WGIPEM carries out its modelling work by sharing and discussing simulation results, identifying gaps in knowledge in these modelling activities, and recommending and performing activities to improve model performance.
An important component of WGIPEM is the continued development of end-to-end ecosystem models that incorporate ecological, economic, and social science. The group forms an important liaison between the biophysical modelling community that produces spatially-explicit estimates of various components of ecosystems and the managers charged with giving advice on the status of those systems and their living marine resources.
WGIPEM meets once a year and proposes workshops and theme sessions on hot topics in the modelling of ecosystem dynamics. Members of WGIPEM identified five key topic areas at the kick-off meeting of this group in 2012:
Understanding the dynamics of primary and secondary production in marine systems and the two-way coupling of lower and upper trophic level models.
Representing the movements of fish and other living marine resources from local (foraging) to regional (migration) scales.
Projecting the impacts of climate change and variability on the productivity and distribution of key species and the composition of marine foodwebs.
Quantifying and conveying uncertainty within various modelling approaches and comparing estimates obtained across models of different levels of complexity.
Coupling novel aspects of socio-economic and ecological science within end-to-end models of marine ecosystems and economic sectors.
