Chesapeake Bay Tributary Summaries

2018-01-01 —

The Chesapeake Bay Program and the U.S. Geologic Survey are compiling tributary basin summaries for 12 major tributaries or tributary groups in the Chesapeake Bay Watershed. These summaries summarize the following information: (1) How tidal water quality changes over time; (2) How factors that drive those changes change over time; and (3) Current state of the science on connecting change in aquatic conditions to its drivers.

Nutrient Limitation in Chesapeake Bay and its Tributaries

2018-01-01 —

This project is aimed toward better understanding nutrient limitation of phytoplankton in Chesapeake Bay and its tidal tributaries. Leveraging novel statistical approaches and long-term monitoring data sets from the Chesapeake Bay Program Partnership, this project helps understand whether nutrient limitation patterns have changed in response to decades of nutrient reduction efforts.

Chesapeake Bay Tidal Water Quality Trends

2015-06-01 —

The Chesapeake Bay Program, MD Department of Natural Resources, and VA Department of Environmental Quality collaborate annually to produce bay-wide summaries of water quality trends in the tidal waters. These annual estimates at more than 150 stations for nutrients, dissolved oxygen, Secchi depth, chlorophyll a and other parameters help gauge the health of the bay and identify changes due to management actions and climate.
