HCMR is a large state research centre, supervised by The General Secretariat of Research and Technology. HCMR consists of three Institutes with over 200 specialists in all fields of oceanography, fisheries, aquaculture, and inland waters. The Institute of Oceanography (IO) was established in 1985, evolving from the former Institute of Oceanography and Fisheries Research (IOFR, 1975-1985). Today it is considered as one of the main providers of oceanographic research in the Eastern Mediterranean, and it is the most comprehensive research institute for the marine environment in Greece, acting in several cases as the official consultant to the Greek government on marine and maritime issues.
