Abstract: | A method is presented to study the carbohydrate composition of marine objects involved into sedimento- and diagenesis (plankton,
particulate matter, benthos, and bottom sediments). The analysis of the carbohydrates is based upon the consecutive separation
of their fractions with different solvents (water, alkali, and acid). The ratio of the carbohydrate fractions allows one to
evaluate the lability of the carbohydrate complex. It is also usable as an indicator of the biogeochemical processes in the
ocean, as well of the genesis and the degree of conversion of organic matter in the bottom sediments and nodules. The similarity
in the monosaccharide composition is shown for dissolved organic matter and aqueous and alkaline fractions of seston and particulate
matter. |
