Main classes of organic matter (OM) in marine water (carbohydrates, proteins, lipids, hydrocarbons, and nucleic compounds) were studied in 0 - 300 strata of the Southeastern part of the Australian depression in the Indian Ocean. Samples at 11 stations were taken, and concentrations of different OM classes were determined. Carbohydrates content is 80% of total OM and 90% of its dissolved part. Compounds with molecular mass less than 10 kDa were predominant in the OM composition. The hydrocarbon contamination was registered in the Northeastern part of the area, with the highest value at the depth of 150 m. Its presence was connected with the penetration of an extraneous water stream.
