The OOI core sensor suite comprises the instruments and sensors that will address the key science themes of the Ocean Observatories Initiative. This set of core sensors was derived from the OOI Science Requirements.
Moored platforms provide oceanographers the means to deploy sensors at fixed depths between the seafloor and the sea surface and to deploy packages that profile vertically at one location by moving up and down along the mooring line or by winching themselves up and down from their point of attachment to the mooring.
Mobile platforms provide oceanographers the means to deploy sensors and move them through space, both horizontally and vertically. OOI uses propeller-driven Autonomous Underwater Vehicles (AUVs) and buoyancy-driven gliders to meet the requirements for oceanographic sampling.
