From 19 – 23 June the first JERICO-NEXT summer school was held near The Hague (the Netherlands). Twenty-one early career scientists from various disciplines learned about multi-disciplinary monitoring and data analysis. The nearby Sand Motor pilot project area was used as an illustration of the multi-disciplinary approach during the field work and hands-on exercises. Lectures addressed the JERICO-NEXT research infrastructure for coastal waters, monitoring methods, data management and the application of multi-disciplinary data for MSFD and research projects. Several multi-disciplinary research projects were presented in more detail: NatureCoast (on coastal defense), Seacams (on tidal renewable energy) and JMP-EUNOSAT (on MSFD eutrophication descriptor). All-in-all, the students spent an inspiring and pleasant week together by the sea.
