The Cape Verde Summer School on “Ocean Biodiversity and Management and Seafloor Structures” was organized jointly by the “Helmholtz Ocean System Science and Technology” (HOSST) research school of GEOMAR and Kiel University, Kiel, Germany and the “Transatlantic Ocean System Science and Technology” (TOSST) research school of Dalhousie University, Halifax, Canada in cooperation with the Instituto Nacional de Desenvolvimento das Pescas (INDP) MIndelo, Cabo Verde. The theme of the Summer School focused on how ocean system science and technology can contribute to ecosystem-based management of marine biodiversity. Participants included the Kiel- and Halifax-based graduate students, as well as students from Cabo Verde and other countries of West Africa (Togo, Benin, Mauretania). The Summer School combined lectures by HOSST, TOSST and Cabo Verdian scientists, visits to local scientific facilities (CVAO), markets and industries, participation in the “International Marine and Atmospheric Science Symposium”, oceanographic and intertidal sampling, snorkeling, a field trip on Fogo, as well as an island-wide beach cleanup. The students were exposed to local culture as much as possible by visiting villages. The students used an interdisciplinary approach and the knowledge gained from their experiences on the ground, to prepare a proposal for a 10-year science plan on potential priorities for the new Ocean Science Centre Mindelo (OSCM). Through presentations, the students received feedback on the feasibility and interest of their proposals by Cape Verdian scientists and HOSST and TOSST instructors.
