Data collected, maintained, and freely disseminated by the OOI makes it possible to measure and directly observe both short-lived episodic events and longer-term changes occurring in the ocean to better understand ocean processes.

These observations are helping to advance what is known about significant scientific challenges, such as coupling between the atmosphere and ocean, coastal ocean dynamics, climate and ecosystem health, the global carbon cycle, plate-scale seismicity, and linkages between seafloor volcanism and life.
