(a) A 2002 tracer study on the Red Cedar River, Michigan using fluorescein as a tracer. Top panel: "Instantaneous" release of the dye from a bridge. Middle: dye plume during the initial stages of mixing. Bottom panel: students sampling at a downstream location (b) Making preparations for a "continuous release" tracer study on the Portage - Burns waterway, a "freshwater estuary" of Lake Michigan in Indiana with colleague Dr. Richard Whitman (USGS) (c) Continuous release of rhodamine-WT
(d) MSU faculty, staff and students who helped with sampling in a dual-tracer study we conducted on the Grand River, Michigan in 2006. We used rhodamine-WT and bacteriophage P22 as tracers and released them "instantaneously" at the same location. Prof. Joan Rose and her group helped with P22 preparation and sampling (e) Plume during the initial stages of mixing
