Platinum deposits of the Goodnews Bay district, Alaska
John Beaver Mertie Jr.
1976, Professional Paper 938
Platinum placers were discovered in 1926 in a small area south of Goodnews Bay, in southwestern Alaska. Beginning in 1927, the placers were worked for 7 years by small-scale mining methods; in later years dragline excavators and a dredge were utilized. These deposits are important, not only because they are...

1976, Professional Paper 987
From May 1968 to December 1972, an industrial organic waste was injected at rates of 100 to 200 gallons per minute (6.3 to 12.6 litres per second) into a sand, gravel, and limestone aquifer of Late Cretaceous age by Hercules Inc. located near Wilmington, North Carolina. This report presents both...
Effect of irrigation pumping on desert pupfish habitats in the Ash Meadows, Nye County, Nevada
William W. Dudley Jr., J. D. Larson
1976, Professional Paper 927
The Ash Meadows area, at the southern tip of the Amargosa Desert in southern Nevada, discharges ground water collected over several thousand square miles of a regional flow system developed in Paleozoic carbonate rocks. Water moves westward across fault contacts from the bedrock into poorly interconnected gravel, sand, and terrestrial-limestone...

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...
Laboratory hydraulic calibration of the Helley-Smith bedload sediment sampler
Leroy Druffel, W. W. Emmett, V.R. Schneider, J. V. Skinner
1976, Open-File Report 76-752
The Helley-Smith bedload sampler operates on a pressure-difference principle and consists of an expanding nozzle, nylon-mesh sample bag , and external components for structural integrity and stability under flow conditions. The Helley-Smith bedload sampler has a hydraulic efficiency, the ratio of the mean velocity in the sampler nozzle to the...
