Organic matter in the White Sea: Interannual variability of organic matterdistribution

The data on the comparative analysis of the distribution of dissolved organ ic matter (DOM) in the White Sea according to the results of the 1991 and 1 997 summer expeditions are presented. The principal distribution features, caused by hydrological conditions in the White Sea bays and basin, art: sho wn to be conserved. The interannual variability of the intensity of the pro duction-destruction processes in the sea areas studied causes significant v ariations of the DOM contents in the photic layers of both the bays and the basin.
