This paper presents experimental results of a turbulent neutrally-buoyant jet vertically discharged in a stagnant ambient and of the same jet discharged in a flow field of regular waves. The main results of the present study indicate the following: 1) Comparison of the root-mean square of turbulent velocity components indicates the effect of wave presence. Particularly, the root-mean square of turbulent velocity components for sections further from the nozzle are consistently greater than those of the same jet discharged in stagnant ambient. 2) The root-mean square of the turbulent velocity components of jets in wave environment are greater than for the same jet in stagnant ambient, at least in cross sections particularly far from the nozzle. 3) For cross sections further from the nozzle, the experimental values of shear turbulent Reynolds stresses indicate that for configurations with the presence of wave motions, an inversion of the sign compared to the jet issued in quiescent ambient occurs.
