The OOI manages and integrates data from more than 800 instruments deployed on its five arrays. Instruments are located on both fixed and mobile platforms including surface buoys, inductive mooring cables, seafloor junction boxes, profilers, gliders, Autonomous Underwater Vehicles. Overall, nearly 75 models of specialized instrumentats are used throughout the OOI, continuously collecting more than 200 unique data products.

Instruments on OOI arrays consist of Core Instruments, those that are integral to the OOI’s data collection infrastructure, and PI instruments, which have been added to the arrays to collect specific data to either test hypotheses or conduct specific experiments. Researchers who are interested in adding an instrument to OOI’s Regional Cabled Array or uncabled moorings can find more information here.
