摘要

This report presents a summary of data collected and an updated progress report for a long-term benthic study conducted to measure the long-term effects of power plant operations on benthic populations and to identify long-term trends and annual cycles in these populations. Benthic organisms and the physical/chemical characteristics of sediments and water were sampled between July 1981 and May 1982 in the mesohaline portion of the Chesapeake Bay and the Potomac estuary. The surveys were concentrated near the Morgantown and Calvert Cliffs, Maryland power plant. Salinities during 1981-1982 were high relative to long-term salinity records with the deviation from average salinities being larger in the Potomac than the mainstem of the Bay.
