Three-component ocean current meter near-bottom current measurements can constrain oceanographic pressure gradients and thus contribute to pressure geodesy and to an understanding of seismic noise that might be confused with tremor.

OI RCA current meter data can be viewed and downloaded through the OOI Data Explorer or accessed via the OOI Machine to Machine Application Programming Interface.
