A study of the distribution of nutrient matters in the McMurdo saline lakes is presented, along with the laboratory and field methods used for the analyses of highly saline water. The presence of a large amount of nitrogen compounds in and around the lakes is pointed out and their source is discussed together with the distribution pattern of different nitrogen compounds in the water. Nutrient matters and chemical elements are considered to have been leached from the lake sediments during the formation of the lakes. The δD and δ^<18>O values in the east and west lobes of Lake Bonney are used in an attempt to explain the processes involved in their formation.
