Lead-, zinc-, and barite-bearing samples from the western Brooks Range, Alaska, with a section on petrography and mineralogy
Irvin L. Tailleur, Ray Wehr, G. Donald Eberlein
1970, Open-File Report 70-319
Concentrations of base metal and barite of potential economic significance may be present in the western De Long Mountains, northwestern Alaska. Greater than 2 percent lead and 1 percent zinc were detected semiquantitatively in sulfide-bearing hand samples from one locality, and more than 10 percent lead was analyzed in a...
A continuing program for estimating ground-water pumpage in California--Methods
William Ogilbee, Hugh T. Mitten
1970, Open-File Report 70-246
Municipal and agricultural ground-water pumpage is being estimated for the principal ground-water basins in California. Because of its anticipated use in analog or digital hydrologic models, agricultural pumpage is estimated for unit areas.Estimated municipal pumpage is based on census figures and population projections and on pumpage reported by organizations in...
Chemical and biological conditions in Bald Eagle Creek and prognosis of trophic characteristics of Foster Joseph Sayers Reservoir, Centre County, Pennsylvania
Herbert N. Flippo Jr.
1970, Open-File Report 71-109
Foster Joseph Sayers. Reservoir will b.e impounded on moderately fertile soils; however, its water source, Bald Eagle Creek, is a bicarbonate-water stream that is over~y-enriched with nutrients. About 650 of the 1,730 acres to be inundated in summer are subject to infestation with aquatic weeds. Nuisance algal "blooms" are expected...
A proposed streamflow-data program for Utah
G.L. Whitaker
1970, Open-File Report 71-322
An evaluation of the streamflow data available in Utah was made to provide guidelines for planning future programs. The basic steps in the evaluation procedure were (1) definition of the long- term goals of the streamflow-data program in quantitative form, (2) examination and analysis of all available data to determine...
Atlantic Continental Shelf and Slope of the United States - Ostracode zoogeography in the southern Nova Scotian and northern Virginian faunal provinces
Joseph E. Hazel Jr.
1970, Professional Paper 529-E
Ostracodes were identified from 236 bottom samples taken in the region from Nova Scotia to Long Island. There is a distinctive difference between the assemblages in the northern and southern parts of this region. Many sublittoral cryophilic species are not present south of Cape Cod or the Northeast Channel, and...
Satellite relay telemetry of seismic data in earthquake prediction and control, 1968 and 1969
W. H. Jackson, Jerry P. Eaton
1970, Open-File Report 70-173
This report describes the progress of the Satellite Telemetry Earthquake Monitoring Program during the period 1 July 1968 through 30 June 1969. This research was supported by the National Aeronautics and Space Administration under Contract No. R-09-020-011, Task No. 160-75-01-50-10.The project was initiated in FY 1968 to evaluate the applicability...
LASA anomalies and their relations to crust and upper-mantle structure
H. M. Iyer, A.R. Jackson, J. H. Healy, T.E. Landers
1970, Open-File Report 70-170
Body-wave data from nine teleseisms recorded at the Large Aperture Seismic Array (LASA), Montana, have been analyzed. The events were at different azimuths and distances from LASA. Apparent-velocity measurements using arrival-time data at the subarrays differed by about 30 percent for events in the northwest and southeast directions.Apparent velocities were...
Measurement of mixing characteristics of the Missouri River between Sioux City, Iowa, and Plattsmouth, Nebraska
Nobuhiro Yotsukura, Hugo B. Fischer, William W. Sayre
1970, Water Supply Paper 1899-G
Measurements of longitudinal dispersion, transverse mixing, channel geometry, and transverse velocity distribution were made in the Missouri River at a flow of about 33,000 cubic feet per second. The results show that the longitudinal dispersion coefficient for the 141-mile reach from Sioux City, Iowa, to Plattsmouth, Nebr., is about 16,000...
Hydrographic and sedimentation survey of Kajakai Reservoir, Afghanistan
Don C. Perkins, James K. Culbertson
1970, Water Supply Paper 1608-M
A hydrographic and sedimentation survey of Band-e Kajakai (Kajakai Reservoir) on the Darya-ye Hirmand (Helmand River) was carried out during the period September through December 1968. Underwater mapping techniques were used to determine the reservoir capacity as of 1968. Sediment range lines were established and monumented to facilitate future sedimentation...
Water resources and related geology of Dera Ismail Khan district, West Pakistan, with reference to the availability of ground water for development
J. W. Hood, Lutfe Ali Khan, Khalid Jawaid
1970, Water Supply Paper 1608-K
Dera Ismail (D.I.) Khan District contains an area of 3,450 square miles between the right bank of the Indus River and the Sulaiman Range in westcentral West Pakistan. Agriculture is the principal source of income in the District, but only a small part of the arable land is fully utilized....
