Chesapeake Bay Summer Forecast:

For the past several years, Chesapeake Bay scientists have collaborated with EcoCheck (NOAA-UMCES partnership) to forecast Chesapeake Bay summer dissolved oxygen conditions, based on flow and nutrient loading conditions through May. Ecological forecasts provide resource managers with information that can be used to guide restoration, enable proactive communication of Bay conditions, and help direct research activities.

2012 forecast predicts moderate conditions

Hypoxia forecast
For the sixth year in a row, EcoCheck has provided a July hypoxia forecast in collaboration with Don Scavia and his group at the University of Michigan. The July 2012 hypoxia forecast predicts moderate conditions, based on Susquehanna total nitrogen loads from January through May.

Maryland Department of Natural Resources has reported on the early June dissolved oxygen conditions in the Maryland mainstem portion of the Bay. For updates throughout the summer, visit
