During the 1976-77 austral summer, geochemical studies were carried out to elucidate the distributuion of organic constituents in lake waters, sediments, soils and epibenthic algae collected from Ross Island and the Dry Valleys of the McMurdo Sound region. The contents of the total organic carbon (TOC) and organic carbon extractable with ethyl acetate (EOC) of lake waters showed a wide range of variation depending on the sampling depths and locations. TOC, total-N and EOC of sediments and soils showed low values, which may reflect the low productivity of the lakes and their environments. The contents of hydrocarbons of lake waters, sediments and soils were fairly low, but characteristic, branched and unsaturated, hydrocarbons were found as the major constituents. Generally the contents of fatty acids of lake waters, sediments and soils were also low and their constituents showed a pattern similar to that of algal fatty acids. m- and p-Hydroxybenzoic and o- and p-hydroxyphenylacetic acids were identified and the presence of o-hydroxybenzoic and vanillic acids was suggested for lake waters and sediments. p-Hydroxybenzoic acid is dominant among the phenolcarboxylic acids identified. The lack of syringic, p-coumaric and ferulic acids in lake waters, sediments and soils must reflect the absence of vascular plants. The analytical results for epibenthic algae suggest that they are one of the important source organisms of organic compounds found in lake waters and sediments.
