Nutrient Sensor Action Challenge

Nutrient Sensor
The University of Maryland Center for Environmental Science (UMCES) and Maryland Department of Natural Resources were named one of five winners of a $10,000 Stage 1 Prize in the Environmental Protection Agency's national Nutrient Sensor Action Challenge.

UMCES and Maryland Department of Natural Resources worked together to detail a plan for using newly developed nutrient sensors to explore questions related to the infilling of Conowingo Dam and how storm events will impact water quality in the Chesapeake Bay. The project would place two sensors in the Upper Chesapeake Bay to provide data on the speed and extent of nutrient pulses into the Bay during storm events. This can help validate models for Chesapeake Bay restoration and give insight into the effect these nutrients - nitrogen and phosphorous - will have on algal blooms and dead zones in the estuary.

NSAC logoThe Nutrient Sensor Action Challenge is a collaboration between the U.S. Environmental Protection Agency, the United States Geological Survey (USGS), the United States Department of Agriculture (USDA), the National Institute of Standards and Technology (NIST) and the National Oceanic and Atmospheric Administration (NOAA)-led U.S. Integrated Ocean Observing System (U.S. IOOS).
Nutrient Sensor 1 is installed at the Maryland Department of Natural Resources Eyes on the Bay 'Arundel on the Bay' station.
Nutrient Sensor 2 is installed at the Maryland Department of Natural Resources Eyes on the Bay 'Dares Beach Pier' station.
Both stations are located on the Chesapeake Bay, MD, USA.
