Late Paleozoic depositional trends in the central Appalachian Basin
Kenneth J. Englund, Roger E. Thomas
1990, Bulletin 1839-F
Trends in the regional extent, stratigraphical distribution, and character of upper Paleozoic terrestrial rocks in the central Appalachian basin were influenced by depositional events associated with basin evolution. Most of these rocks originated as siliciclastic detritus eroded from tectonic highlands that were elevated by plate collision along the southeastern margin...

John A. Moody, Bradford Butman, Polly Shoukimas, Terence G. Donoghue
1990, Open-File Report 90-350
This report presents hydrographic data obtained on R/V OCEANUS Cruise 181 from February 5-15, 1987. The hydrographic measurements (pressure, temperature, salinity, oxygen, beam attenuation, phosphate, silicate and nitrate/nitrite) were obtained in Georges, Jordan, and Wilkinson Basin in the Gulf of Maine and directly east of Boston across Massachusetts Bay as...

1990, Water-Resources Investigations Report 89-4186
Samples collected from wells in Carroll and Guthrie Counties, Iowa, were analyzed to describe the chemical quality of the ground water in shallow aquifers. The study began in June 1986 with the selection of 20 shallow wells in Carroll County and 22 shallow wells in Guthrie County. These wells were...
Sources and distribution of nitrate in ground water at a farmed field irrigated with sewage treatment-plant effluent, Tallahassee, Florida
M. P. Berndt
1990, Water-Resources Investigations Report 90-4006
The city of Tallahassee, Florida began applying sewage treatment-plant effluent to a sprayfield southeast of the city in 1980. Fertilizers containing inorganic nitrogen were also applied in conjunction with the operation of a commercial farm at this site. Analysis of groundwater in the surficial aquifer and the Upper Floridan aquifer...
Continuous seismic reflection profiling of hydrogeologic features beneath New River, Camp Lejeune, North Carolina

1990, Water-Resources Investigations Report 89-4195
A medium-power, wide-frequency seismic system was used to collect more than 100 miles of continuous seismic reflection profiling data over a 4- day period along a 24-mile segment of the New River estuary and Intracoastal Waterway. The seismic reflection data were evaluated to determine the continuity of aquifer sediments and...
