What is OOI?

THE VISIONTo launch an era of scientific discovery across and within the ocean

basins, utilizing widely accessible, scalable, interactive telepresence

Why do we need OOI?

Oceanography since it began has been an expeditionary science. OOI will allow humanity tointeract with the ocean 24:7 365.

Objective: To provide a realoceanographic test bed in which

the designed CI technologies willsupport field operations of ships

and mobile p latforms, aggregate

data from fixed platforms, shore-

based radars, and satellites and

offer these data streams to data

assimilative forecast models.

Goal: To use mult i-model forecaststo guide glider deployment and

coordinate satellite observing.
