HCMR is a governmental research centre operating under the auspices of the General Secretariat for Research and Technology (Greek Ministry of Education). It has the mandate to promote basic research in all fields of the aquatic environment and to deliver comprehensive scientific and technical support to the public. HCMR operates the 62m R/V Aegaeo, the 23m R/V Filia, four ROVs, the manned submersible THETIS, as well as two aquariums in Crete and Rhode Islands. It is composed of three institutes: Oceanography, Marine Biological Resources & Inland Waters, Marine Biology, Genetics &Aquaculture.
The Institute of Oceanography (IO) is the only Institute in Greece that conducts multidisciplinary, physical, chemical, biological and geological, marine and coastal research. This research is accomplished through field measurements, analysis and field and laboratory experiments and through the study of characteristics and processes in the marine environment, at the ocean bottom, in the solid earth underneath the seafloor, the atmosphere and land. The IO has significant experience in Operational Oceanography through the participation in numerous national and European funded projects and most of all through the development and operation of the POSEIDON operational system (www.poseidon.hcmr.gr). Daily marine biogeochemical forecasts are provided both to scientists and public at several resolutions extending from the Mediterranean basin down to the Aegean.
HCMR has contributed to a large number of international research projects in the Mediterranean and the Black Seas, e.g. GLOBEC, CLIVAR, GOOS, the IOC. It is an active member of EuroGOOS & MedGOOS by developing a national monitoring/forecasting programme through the POSEIDON programme and by participating in EC and ESA funded research projects (MFSPP, MFSTEP, MERSEA_S1, ROSES, MERSEA_IP, MARCOAST, ECOOP, MyOcean, BOSS4GMES, EuroSITES, EuroARGO, JERICO, FixO3) to develop European capacity in operational oceanography under the GMES and GEOSS umbrella. Furthermore HCMR coordinates the GreekEMSO and Greek Argo ESFRI projects.
