Dr. Claire Schelske’s current research is directed toward eutrophication of the Laurentian Great Lakes and shallow lakes in Florida, particularly Lake Apopka. Specific research topics include the biogeochemistry of phosphorus, silica, and iron, experimental studies of nutrient and trace limitation on biological productivity, and ecological applications of stable carbon and nitrogen isotopes. His work includes paleolimnological studies of nutrient enrichment and lacustrine productivity, lacustrine investigations at the ecosystem level, and lake restoration.
