The Instituto de Ciencias Marinas de Andalucía (ICMAN) in Cadiz, which belongs to the CSIC, has more than 40 years of research experience focused on a variety of topics ranging from local, coastal and estuarine ecosystem management to basin scale ocean dynamics and biogeochemical fluxes. Since 2011, the ICMAN has been integrated, as a founder member, in the CEI·MAR (Campus of International Excellence of Sea/Oceans) which is coordinated by the University of Cadiz. The Department of Ecology and Coastal Management has a broad experience in the study of the physical-biological coupling in several marine eco-regions, such as the Gulf of Cádiz, Strait of Gibraltar, Alboran Sea and the Antarctic, also with application of this knowledge in terms of integrated protection of coastal zones. In particular, the Ecosystems and Oceanography research group carries out projects aimed at providing a comprehensive understanding of the responses of the coastal zone both to human actions and to accelerating climate change, by means of the thorough analysis of interactions between marine biogeochemical cycle and the pelagic ecosystem.
