Supplement to: Slavik, Kaela; Lemmen, Carsten; Zhang, Wenyan; Kerimoglu, Onur; Klingbeil, Knut; Wirtz, Kai W (2019): The large-scale impact of offshore wind farm structures on pelagic primary productivity in the southern North Sea. Hydrobiologia, 845(1), 35-53, https://doi.org/10.1007/s10750-018-3653-5

The increasing demand for renewable energy is projected to result in a 40-fold increase in offshore wind electricity in the European Union by 2030. Despite a great number of local impact studies for selected marine populations, the regional ecosystem impacts of offshore wind farm structures are not yet well assessed nor understood. The study resulting from this dataset investigates whether the accumulation of epifauna, dominated by the filter feeder Mytilus edulis (blue mussel), on turbine structures affects pelagic primary production in the southern North Sea.

The data set contains spatially resolved annual values of net primary production (NPP) for the years 2003-2013 for two scenarios from simulations that include the ecosystem model MAECS (Model for Adaptive Ecosystems in Coastal Seas), the hydrodynamic model GETM (General Estuarine Transport Model), the biochemical model OMEXDia (Ocean Margin Experiment Diagenesis) and reconstructed blue mussel distribution, all coupled through MOSSCO (Modular System for Shelves and Coasts).

Besides the reference scenario (REF), an Offshore Wind Farm (OWF) scenario includes additional filtration by epistructural blue mussels assuming a build-up of OWF as projected in 2030.
