The new abilities for long range ocean monitoring arising with underwater parametric array application are discussed. The results of single mode waveguide excitation in broad frequency band are presented. The effect of broadband single mode signal compression due to waveguide dispersion that leads to signal intensity increase in process of it propagation is shown. The results of the experimental research of specific features propagation of broadband sound signal generated by parametric array in shallow water are discussed. Some prospective of sharp directed parametric array application for marine environment research is considered.
