Abstract

Changes in S concentration in sediment profiles from South Lake (Adirondack region, New York, USA) and Ledge Pond (western Maine, USA) indicated an increased input of S beginning around 1850. This S was probably derived from anthropogenic sources. The S budget for South Lake indicated that sedimentation of seston rich in S (∼0.9% dry mass) accounts for most of the input of S in sediment. Sulfur in both seston and sediment is primarily organic (57 and 22% ester sulfate, 32 and 52% carbon-bonded S, respectively). The transformation and translocation of organic S constitutes a major pathway of S flux in South Lake.
