Feeding flights of nesting wading birds at a Virginia colony Feeding flights of nesting wading birds at a Virginia colony
Feeding flights of Snowy Egrets (Egretta thula), Tricolored Herons (E. tricolor), Little Blue Herons (E. caerulea), and Cattle Egrets (Bubulcus ibis) were monitored at a small nesting colony near Chincoteague, Virginia during late May and June 1979. All four species varied their flight directions over a series of days. Cattle Egrets oriented in a different direction (toward uplands) from...

A water-quality study of the tidal Potomac River and Estuary — An overview A water-quality study of the tidal Potomac River and Estuary — An overview
The U.S. Geological Survey began a 5-year interdisciplinary study of the tidal Potomac River and Estuary in October of 1977. The objectives of the study are: (1) to provide a basic understanding of physical, chemical, and biological processes; (2) to develop flow and transport models to predict the movement and fate of nutrients and algaes and (3) to develop efficient techniques for the...
Methods for the collection of geochemical data from the sediments of the tidal Potomac River and estuary and data for 1978-1980 Methods for the collection of geochemical data from the sediments of the tidal Potomac River and estuary and data for 1978-1980
The chemical composition of bottom sediments and their associated pore waters from the tidal Potomac River and Estuary was studied from May 1978 through June 1980. Pore waters were routinely analyzed for pH, Eh, alkalinity, and concentrations of sulfide, sulfate, phosphate, carbon, ammonium, silica, iron, manganese, chloride, sodium, potassium, calcium, and magnesium. Porosity, weight...

Distribution of submersed aquatic macrophytes in the tidal Potomac River Distribution of submersed aquatic macrophytes in the tidal Potomac River
Results of a 3-year survey (1978?1980) and review of historic trends have shown a major decline in the number of species and the distribution of submersed aquatic macrophytes in the tidal Potomac River since the early 1900's. The freshwater tidal river is essentially devoid of plants and only very sparse populations remain in the mesohaline section of the estuary. Present plant...

Water quality data for selected streams tributary to the tidal Potomac River and Estuary, Maryland and Virginia, 1979-81 water years Water quality data for selected streams tributary to the tidal Potomac River and Estuary, Maryland and Virginia, 1979-81 water years
Observations of the physical, chemical, and biological water quality of five streams draining to the tidal Potomac River and Estuary during the 1979-81 water years are tabulated. The streams sampled are Rock Creek, the Northwest and Northeast Branches of the Anacostia River, the Occoquan River, and St. Clements Creek. Samples, usually collected during storms, were routinely analyzed for...
