Phytoplankton Productivity In The Tidal Regions Of Four Chesapeake Bay (U.S.A.) Tributaries, Kneeland K. Nesius, Harold G. Marshall, Todd A. Egerton
Phytoplankton Productivity In The Tidal Regions Of Four Chesapeake Bay (U.S.A.) Tributaries, Kneeland K. Nesius, Harold G. Marshall, Todd A. Egerton
Virginia Journal of Science
Monthly and annual phytoplankton productivity rates of four Virginia tidal rivers were determined based on a 12-year monitoring study that included sampling stations from tidal freshwater, oligohaline, and mesohaline regions in these rivers. The mean monthly rates and range at these locations were 5.52 (Dec.) to 175.12 (Aug.) mg C m-3 h-1 for tidal freshwater, 12.21 (Jan.) to 149.90 (May) mg C m-3 h-1 in oligohaline regions, and 16.20 (Jan.) to 151.33 (May) mg C m-3 h-1 for the mesohaline. The estimated mean annual 12 year productivity for the different Virginia river sites in …

The Chesapeake Bay is one of the country's most productive estuaries. However, for decades the health of the Bay has been declining due in large part to nutrification. Excessive nutrients encourage algal blooms, which lower dissolved oxygen and increase turbidity in the Bay's waters. More than 40% of the Bay's main stern is now dead largely as a result of this problem. The practice of chumming, the discarding of baitfish, usually menhaden, over the sides of fishing boats to attract game fish like striped bass, is contributing to the Bay's nutrification problem because the decomposing chum raises the waters biological …
Chumming On The Chesapeake Bay And Complexity Theory: Why The Precautionary Principle, Not Cost-Benefit Analysis, Makes More Sense As A Regulatory Approach, Hope M. Babcock
Georgetown Law Faculty Publications and Other Works
Estuaries like the Chesapeake Bay ("Bay") and Puget Sound are in grave trouble. They each suffer from poor water quality, loss of habitat, and declining biodiversity, and efforts to restore their health are straining both public and private resources. While accomplishments are often recorded in the fight against these ills, it is clear these accomplishments "are not yet equal to the scale of the problems." The focus of this article is on the nation's largest estuary, the Bay. Despite the investment of billions of dollars to improve water quality, the Bay continues to suffer from severe environmental degradation that impairs …
