A method is provided for improving horizontal spatial resolution of a flow field in compact jet-like current features so as to quantify the axial velocity in the cross section of a compact jet using an Acoustic Doppler Current Profiler ADCP. The ADCP is a four-beam, Janus-type ADCP having beams aligned so that each of the beams is at an angle of about 200 to 300 to vertical and at 450 to the fore and aft axis of the vessel, such that two beams point at 450 to forward and two pointing 450 to aft. The measurements from each range bin of the aft-facing beams are combined with the previously measured samples from the corresponding forward-facing beams at the same position along the vessel track.
