In order to investigate carbonaceous matters in the seawater and some elements of the carbon cycle, possibilities of joint use of laser induced breakdown spectroscopy (LIBS) and laser induced fluorescence (LIF) of seawater are considered in the paper. The data were obtained in the shelf zone of the Sakhalin Island and in the Amur River estuary. So investigated sea waters contain dissolved organic matters determined by either phytoplankton cells activity or anthropogenic and terrigenous sources. In some regions the linear correlation between carbon emission line of seawater LIBS spectra and fluorescence intensity of dissolved organic matter in seawater induced by green or ultraviolet radiation were observed. It has been shown that joint use of LIBS and LIF methods in seawater gives the possibility of efficient obtaining of additional information about the content, origin or types of carbonaceous matters in seawater.
