We present results of study of organic matter in the coastal and bottom sediments of the Laptev Sea (Buor-Khaya Gulf). The study has shown the regularities of organic-matter distribution in the shelf zone adjacent to the glacial coast. The coast composed of a glacial rock complex supplies the largest amount of organic material to the sea as compared with other types of the coast. The average content of organic matter in these strata is ~ 2-3%. The bottom sediments of the shallow littoral zone are significantly depleted in organic carbon (0.1-0.3%) as a result of their active rewashing and the transition of finely dispersed material (mainly organic one) toward the deep sea zones.
