Digital-simulation model of the Wenonah-Mount Laurel Aquifer in the coastal plain of New Jersey
Bronius Nemickas
1976, Open-File Report 75-672
A digital computer-simulation model of the Wenonah-Mount Laurel aquifer is used to evaluate the aquifer's capabilities of meeting the projected future demands and to study the cause of the rapidly declining water levels. The modelled area includes 1,500 square miles (3,885 square kilometres) of the New Jersey Coastal Plain and...

Hard rock uranium potential in Alaska
Thomas P. Miller
1976, Open-File Report 76-246
Discussing the potential of "hardrock" (i.e., non-sedimentary type) uranium deposits in a 586,000 mi2 portion of the North America Cordillera is a difficult task compounded by the fact that the remoteness of much of the region and the logistical difficulties have resulted in only reconnaissance geologic information being available for...

Hydrologic studies of the U.S. Geological Survey related to coal development on Colorado
Water Resources Division, U.S. Geological Survey
1976, Open-File Report 76-549
This report summarizes the hydrologic studies related to coal development being conducted by the U.S. Geological Survey in the State of Colorado. The objective of the hydrologic data-acquisition program is to collect surface-water quality and quantity data and ground-water level records. These data are needed to define predevelopment conditions and...
Summary of miscellaneous potassium-argon age measurements, U.S. Geological Survey, Menlo Park, California, for the years 1972-74
A.L. Berry, G. B. Dalrymple, M. A. Lanphere, J.C. Von Essen, editor(s)
1976, Circular 727
Potassium-argon age measurements are reported for 61 mineral separates and rock samples from Alaska, Arizona, California, Idaho, Utah, and Washington. The age report for each sample gives location, analytical data, and a brief geologic interpretation....
Changes in the water supply in the Upper Republican Natural Resources District, Southwest Nebraska, from 1952-75
E.G. Lappala
1976, Open-File Report 76-498
Use of ground water for irrigation has increased rapidly in the Upper Republican Natural Resources District in southwestern Nebraska in recent years. The principal aquifer being developed is composed of saturated and gravel of the Ogallala Formation of Tertiary age. Water-level declines of as much as 16 feet (4.9 meters)...
Computer-enhanced LANDSAT imagery as a tool for mineral exploration in Alaska
Nairn Albert, Pat S. Chavez
1976, Open-File Report 76-65
Recent work in the Nabesna and McCarthy quadrangles, Alaska, indicates that computer-enhanced LANDSAT imagery shows many of the known mineral deposits and can help in the prediction of potential mineral occurrences. False color, "simulated natural color" and color ratio techniques, were used successfully in conjunction with a black and white,...

Preliminary space image lineament maps of Alaska
Ernest Hartwell Lathram, Robert G.H. Raynolds
1976, Open-File Report 76-341
Examination of images from Nimbus, NOAA and Landsat satellites has revealed a series of lineaments in the earth's surface in Alaska 1000 km or more in length (fig. 1). These lineaments occur as alinements of surface geologic structures, linear valleys or ridges, and linear changes in tonal contrast marking differences...
Preliminary report on uranium-, thorium-, and rare-earth-bearing rocks near Golovin, Alaska
Thomas P. Miller, Raymond L. Elliott, Warren I. Finch, Robert A. Brooks
1976, Open-File Report 76-710
Uranium-, thorium-, and rare-earth bearing rocks were found by a U.S. Geological Survey field party 15 miles northeast of Golovin, Alaska, in the southeastern Seward Peninsula (fig. 1) in June 1976. The mineralized areas occur in syenite and appear to be concentrated along the margins of alkaline dikes, with allanite...

Water resources data for the 1975 water year for Connecticut consist of records of stage, discharge, and water quality of streams; contents and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report contains discharge records for 56 gaging stations; tidal volume for...

Concentrations of dissolved solids in the Salinas River are variable and range from 164 to 494 milligrams per liter near Bradley and from 170 to 1,090 milligrams per liter near Spreckels. Higher concentrations near Spreckels are caused mainly by sewage inflow about 150 feet (50 meters) upstream. Concentrations of nitrogen,...

James L. Bischoff
1976, Open-File Report 76-548
Probably the single most obvious and important environmental effect during deep-sea mining operations will be the resuspension and discharge of large amounts of sea floor sediment into the water column. The objectives of the geological program, therefore, were two-fold. The first was to provide baseline information on the sediment system...
