The National Institute of Oceanography (NIO) with its headquarters at Dona Paula, Goa, and regional centers at Kochi, Mumbai and Visakhapatnam, is one of the 38 constituent laboratories of the Council of Scientific & Industrial Research (CSIR), New Delhi. NIO was established on 1 January 1966 following the International Indian Ocean Expedition (IIOE) in early 1960s. The institute has grown today into a large oceanographic laboratory of international repute. The focus of research has been on observing and understanding the special oceanographic features that the North Indian basin offers. The inferences from this research have been reported in about 5000 research articles so far.
The institute has about 200 scientists (more than half of them hold doctoral degree) and 100 technical support staff. The major research areas include the four traditional branches of oceanography - biological, chemical, geological/geophysical, and physical - and some other areas such as marine instrumentation and archeology. The institute has well equipped laboratories to conduct research in these and multidisciplinary areas. The institute also operates a coastal research vessel CRV Sagar Sukti, a 23 m vessel equipped for multidisciplinary oceanographic observations. NIO's scientists also have access to the ocean going research vessel ORV Sagar Kanya, operated by the Ministry of Earth Sciences. The institute has a library with 15,000 books and 20,000 back volumes of research journals, making it the best collection of printed literature on ocean sciences in the country.
