Abstract
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 20° to 30° to vertical and at 45° to the fore and aft axis of the vessel, such that two beams point at 45° to forward and two pointing 45° 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.
