GCOS Ocean Physics ECV - Subsurface Currents

Subsurface ocean velocity observations are essential in resolving the wind and buoyancy driven ocean circulation, the complex vertical velocity structure in the major ocean boundary currents, equatorial currents, wave propagations, ocean eddies and submesoscale transport. Vertical velocity profile information can be used to estimate the order of ocean mixing using fine-scale parameterizations of turbulent dissipation by internal wave breaking.
