Sulfur constituents and cycling in waters, seston, and sediments of an oligotrophic lake

Journal Article · · Limnol. Oceanogr.; (United States)
Organic and inorganic sulfur constituents in streams, the water column, seston, and sediments of an oligotrophic Adirondack lake were measured for 2 years (1981-1983). Soluble organic S constituents (C-bonded S and water sulfate) were 1-18% of total S in streams, the water column, and lake outlet. Seston S (0.3-1.2% dry mass) in South Lake consisted of ester sulfate (44-59%), C-bonded S (32-43%), sulfate (10-16%), and nonsulfate inorganic S (<2%). Rates of S deposition measured in sediment traps were highest after spring turnover. The organic matter content (52-81% dry mass) of traps at 5, 8, and 15.5 m showed no significant differences. Net mineralization of seston inputs was 26% based on mass balance calculations, with 43% of the ester sulfate input mineralized. Because most of the S input to the sediments was not mineralized, organic S accumulated and constituted the major (74% of total S) S component of the sediment.
