Seasonal energetics and behavior of captive canvasbacks (Aythia valisineria) Seasonal energetics and behavior of captive canvasbacks (Aythia valisineria)

Dramatic changes in the food habits and distribution of Chesapeake Bay canvasbacks (Aythya valisineria) generated a desire to better understand the energetics and behavior of this species on its wintering grounds. Captive canvasbacks were maintained ad libitum on 5 diets during the winters of 1978-80 to evaluate varying protein and energy levels in the diets. Food consumption, weight...

Primary productivity by phytoplankton in the tidal, fresh Potomac River, Maryland, May 1980 to August 1981 Primary productivity by phytoplankton in the tidal, fresh Potomac River, Maryland, May 1980 to August 1981

Primary productivity by phytoplankton was measured on samples collected from the Potomac Tidal River, Maryland. The studies were performed monthly from May 1980 to September 1981. Additional studies were done once a week in August 1980, twice a week from August 4 to 8, 1980 and twice in September 1980. Depth-integrated samples were collected at five stations and incubated in boxes that...

Benthic phosphorus regeneration in the Potomac River Estuary Benthic phosphorus regeneration in the Potomac River Estuary

The flux of dissolved reactive phosphate from Potomac riverine and estuarine sediments is controlled by processes occurring at the water-sediment interface and within surficial sediment. In situ benthic fluxes (0.1 to 2.0 mmoles m-2 day-1) are generally five to ten times higher than calculated diffusive fluxes (0.020 to 0.30 mmoles m-2 day-1). The discrepancy between the two flux...

Water quality of the tidal Potomac River and estuary hydrologic data report, 1980 water year Water quality of the tidal Potomac River and estuary hydrologic data report, 1980 water year

This report contains data on the physical and chemical properties measured in the Tidal Potomac River and Estuary during the 1980 Water Year. Data were collected routinely at five stations, and periodically at 17 stations including three stations near the mouth of the Potomac River in Chesapeake Bay. Each of the five stations represent a cross section through which the transport of...
