Modelling the role of offshore wind farms in modifying the functioning of coastal food webs and cumulative impact

Duration: 24 months (2016 - 2019)


The environmental impact studies of offshore wind projects focus on considering the sensitivity to potential disturbances of each of the ecological compartments (benthos, birds, marine mammals) in a fractional way. In this context, it is necessary to develop an integrated view of the ecosystem, through the implementation of modelling tools, allowing to consider the trophic food web as a whole. This approach is complementary to those used during impact studies.


To model the role of offshore wind turbines and other human activities in the modification of the food webs in the Bay of Seine.

Scientific and technical content

  • 2D spatial modelling of food webs in the extended Bay of Seine area.
  • Food web modelling integrating isotopes and uncertainty quantification, and statistical testing of the reef effect associated with the Courseulles-sur-mer farm on ecological functioning properties.
  • Modelling of climate changes through the modification of species distribution areas chosen according to trophic models and their commercial value.
  • Modelling of different anthropogenic pressures on the food web.
