Tedesco et al 2016: Capabilities of Baltic Sea models to assess environmental status for marine biodiversity, Marine policy 2016 Nine Baltic Sea ecosystem models were analysed for their potential of addressing
” The general outcome is that the Baltic Sea models considered do not adequately cover all the requested needs of the MSFD, but can potentially do so to a certain extent, while for some descriptors/ criteria/ indicators/ pressures new indicators and/ or modelling techniques need to be developed in order to satisfactorily address the requirement of the MSFD and assess the environmental status of the Baltic Sea”.
