National Oceanographic Data Centre at INCOIS Also recognized as Responsible National Oceanographic Data
Centre (RNODC) by IOC/UNESCO
• INCOIS developed the Ocean Data and Information System (ODIS), a one-stop-shop for various oceanographic data from the Indian Ocean.
• INCOIS receives voluminous and heterogeneous data from various in-situ and remote sensing ocean observing systems in real-time, processes, quality control and disseminate for various operational activities by INCOIS, IMD, Indian Navy, Coast Guard etc. and also provide web-based data services to the users.
• INCOIS also hosts project specific data from different national and international scientific programmes viz., CTCZ, Geotraces, Ocean Biogeographic Information System etc.
