A new study by ICPRB biologist Claire Buchanan and other authors has provided an improved method for assessing nutrient levels in the surface waters of the Chesapeake Bay and will provide an improved way to judge the effects of nutrient reduction best management practices. The regional Chesapeake Bay cleanup is based on reducing nutrients and sediments to restore the waterway’s health. Excessive nutrient levels contribute to algae blooms that cause a succession of water quality problems. Buchanan teamed with scientists from the University of Maryland, the Environmental Protection Agency, U.S. Geological Survey, Maryland Department of Natural Resources, and the Chesapeake Research Consortium to produce Nutrient limitation of phytoplankton in Chesapeake Bay: Development of an empirical approach for water-quality management.

The model can help direct future efforts in nutrient reduction through improved modeling that can increase effectiveness and reduce costs. Future research will focus on the Potomac and other bay tidal tributaries.
