The modern laser technologies of investigation of the Ocean are presented. The development results of the laser methods for lidar sounding of upper ocean layer, monitoring of phytoplankton communities, and measuring the element concentration are dis-cussed. The description of ship-borne lidar hydro complex allowing the retrieval of back scattering structure layer and internal waves is given. Main results of laser-induced fluorometry usage for phytoplankton communities monitoring, undersattelite ocean color validation, and regional algorithms for chlorophyll A retrieval were under consideration. Key outcomes from laser induced breakdown spectroscopy methods development with the use of laser impulse of nanosecond and femtosecond lengths to qualify elements concentration included in sea waters composition and phytoplankton are given.
