AbstractOne of the aims of PERSEUS project is the identification of the most relevant pressures and data/knowledge gaps that potentially put at risk the GES achievement in the Southern European Seas (SES) ecosystems As result of a scientific independent effort, an approach complementary to MSFD has been adopted harvesting and distilling existing scientific knowledge available in SES areas. This synthesis effort, based on the expert judgment, has been projected on the MSFD descriptors, highlighting also the differences between coastal hot spots and the open sea. A comparative analysis of the Initial Assessments (IAs) for five SES countries has been independently performed and a list of impact and knowledge gaps has provided. The knowledge gaps can be considered as priorities in future research agendas. Comparison of results of both analyses demonstrates that they agree on the data gaps found for coastal systems, while, for the open sea, IAs are much less detailed. By contrast, PERSEUS treats the open sea as a separate system and highlights that much less information is available for it. Structural knowledge gaps have been detected for the biodiversity and marine food web descriptors, calling for a substantial improvement of an (operational) understanding of the marine ecosystem composition and functioning. This analysis also allowed the identification of additional research themes (ecosystem resilience, role of gelatinous macrozooplankton, and, more in general, of invasive species in a changing ocean, multiple stressor impact) targeting research topics expected to provide information for an effective implementation of a set of mitigation measures.
