The
Mediterranean Science Commission is the only organization that specializes in multi-lateral marine research in the Mediterranean Sea. Through its network of scientists, it can quickly detect changes and alert governments and others who must take action, and provide neutral and authoritative advice on issues related to marine ecosystems by ways of Monographs, reports, Congresses. In 1993 CIESM responded to a request from the
European Parliament and issued a detailed assessment of Marine Pollution in the Mediterranean. In 1998 CIESM began running research workshops which continue to produce widely read monographs on emerging issues. Subjects have covered a diversity of sectors ranging from marine volcanoes and canyons, marine connectivity, the
Messinian Salinity Crisis, Marine Peace Parks, impacts of
climatic change on the ocean, species extinctions, marine
biotechnologies, deep waters, acidification, emergent pollutants, food webs from marine viruses to whales, invasive species, social studies of fisheries, etc. At that time the Commission started to deliver morphometric maps of the Mediterranean
seabed, based on modern imagery provided by multibeam swath. Between 2013 and 2020 the CIESM JellyWatch program engaged an extensive survey of
jellyfish outbreaks, monitored on a weekly basis in coastal waters from Morocco to the Black Sea. The Commission assumes a leading role in documenting in
CIESM Atlases on Exotic Fishes, Crustaceans, Molluscs, Seaweeds the continuous arrival of tropical invaders in the Mediterranean Sea, mostly from Indo-Pacific origin, and tracks the status and routes of endangered species such as sharks, rays and seabirds. The latest CIESM Congresses were held in Venice (2010), Marseille (2013), Kiel (2016), Cascais (2019), and Palermo (2024). ==Current organization==
