South River Sediment Coring Project Update – October 22, 2003

Slide presentation reporting results from a South River sediment coring effort. It describes rationale and goals, sampling sites (including Dooms’ Dam and a floodplain tributary), total Hg and MeHg depth profiles, Cs‑137 dating to establish chronology, estimated sedimentation rates (0.4–1.5 cm/yr), evidence of historic pre‑1960s mercury releases, and planned storm and water‑column sampling.
