The National Science Foundation-funded Ocean Observatories Initiative (OOI) is an integrated infrastructure program composed of science-driven platforms and sensor systems that measure physical, chemical, geological and biological properties and processes from the seafloor to the air-sea interface.Over 200 unique data products are measured or derived from the nearly 75 models of specialized instrumentation used in the OOI from the air-sea interface, seafloor/crust, and water column. This data is accessible from the OOI data portal.
