Abstract
The study focused on the relationships of phytoplankton and microheterotrophs to the development and maintenance of anoxia in the mesohaline region of the Chesapeake Bay. From February to October 1985, a series of fourteen cruises was made on which water quality, nutrient concentrations, phytoplankton production, and metabolism were assessed. Phytoplankton production from February to May generates a quantity of organic matter more than adequate to cause oxygen decline in mid-bay deep waters. Water column consumption by microheterotrophs is a major contributor to the development of anoxia during the spring and early summer.
