Is it true that surface ocean current velocity changes with depth along a velocity gradient?

Yes. Multiple observational and theoretical studies confirm that surface ocean and water current velocity varies with depth along a distinct velocity gradient due to wind forcing, surface waves, and bottom friction.

The analysis

The claim asserts that surface ocean current velocity changes with depth along a velocity gradient. Retrieved papers explicitly document vertical velocity profiles and velocity shear across the water column in both oceanic and riverine settings, supporting the claim without contradiction.
