IIOE-2 has been developed with joint sponsorship from the Scientific Committee on Oceanic Research (SCOR), the Intergovernmental Oceanographic Commission (IOC) and the Indian Ocean Global Ocean Observing System (IOGOOS) with support from such programs as the Integrated Marine Biogeochemistry and Ecosystem Research (IMBER) and the Sustained Indian Ocean Biogeochemistry and Ecosystem Research (SIBER). IIOE-2 also has strong links with the Indian Ocean Panel (IOP) sponsored by the Global Ocean Observing System (GOOS) and Climate Variability and Predictability (CLIVAR) programs, and the Indian Ocean Observing System (IndOOS) Resources Forum (IRF), both under the auspices of IOGOOS. In addition IIOE-2 will leverage several coastal and open-ocean monitoring programs in the Indian Ocean such as the Indian Ocean Observing System (IndOOS), Australia's Integrated Marine Observing System (IMOS), the Southern Ocean Observing System (SOOS) etc.
