The OOI manages and integrates data from more than 800 instruments deployed on its five arrays. Instruments are located on a myriad of platforms including gliders, Autonomous Underwater Vehicles, surface buoys, profilers, inductive mooring cables, and seafloor junction boxes. Overall, nearly 75 models of specialized instrumentation 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.
