Abstract:
Variations of the dissolved organic carbon (DOC) in natural waters is important not only for studies of the Global Carbon Cycle but also in the optics of hydrosphere (color, turbidity, and fluorescence properties) and atmosphere (greenhouse effect). In this paper we present a short overview of basic techniques for the determination of the DOC and pay special attention to the lively discussion that takes place in the literature about the choice of an optimal measurement technique. Finally, we propose an original technique of measuring DOC and a facility to perform it, namely, the Lutsarev carbon analyzer (LCA). Some results obtained with LCA during the expedition onboard "Il'ya Repin" ship on Volga river in summer of 1993 are discussed.
