Abstract
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 ester 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.
