Generalized altitude and configuration of the water table in parts of Larimer, Logan, Sedgwick, and Weld Counties, Colorado
Ronald G. Borman, Neville G. Gaggiani
1982, Water-Resources Investigations Report 82-4055
The water table in parts of Larimer, Logan, Sedgwick, and Weld Counties, Colorado ranges from about 7,000 feet above the National Geodetic Vertical Datum of 1929 (formerly called mean sea level) in eastern Larimer County to about 3,450 feet in northeastern Sedgwick County. Water is moving to the south and...
Earthquake history of the United States
Jerry L. Coffman, Carl A. Von Hake, Carl W. Stover
Jerry L. Coffman, Carl A. von Hake, Carl W. Stover, editor(s)
1982, Publication 41-1
This publication is a history of the prominent earthquakes in the United States from historical times through 1970. It supersedes all previous editions with the same or similar titles (see page ii) and, in addition to updating earthquake listings through 1970, contains several additions and corrections to previous issues. It...
Massive sulfide deposits of the Southern Appalachians central Virginia volcanic-plutonic belt as a host for massive sulfide deposits
L. Avlides, J. E. Gair, S.L. Cranford
1982, Economic Geology (77) 233-272
Strata-bound massive sulfide deposits of the central Virginia Piedmont occur in a volcanic- plutonic belt composed of Lower Cambrian(?) metamorphosed volcanic rocks and locally of pre-Upper Ordovician, low potassium granitoid rocks. The belt, interpreted as an ancient island arc, begins about 50 km south of Washington, D. C, and extends...
Does the benthos control phytoplankton biomass in South San Francisco Bay?
James E. Cloern
1982, Marine Ecology Progress Series (9) 191-202
South San Francisco Bay, USA, is a shallow coastal embayment that receives large inputs of nutrients (N. P, Si) and small local inputs of freshwater. Phytoplankton dynamics are typically characterized by a spring bloom when surface chlorophyll a increases from < 5 to > 40 mg m-3. The bloom persists...
On Lagrangian residual currents with applications in south San Francisco Bay, California
Ralph T. Cheng, Vincenzo Casulli
1982, Water Resources Research (18) 1652-1662
The Lagrangian residual circulation has often been introduced as the sum of the Eulerian residual circulation and the Stokes' drift. Unfortunately, this definition of the Lagrangian residual circulation is conceptually incorrect because both the Eulerian residual circulation and the Stokes' drift are Eulerian variables. In this paper a...
Annual report of the USGS Mission, Kingdom of Saudi Arabia, for the first year of the sixth extension of the USGS-MPMR work agreement : fiscal year 1401/02, 1 Rajab 1401-30 Jumad Thani 1402 (5 May 1981-23 April 1982)
U.S. Geological Survey Saudi Arabia Mission, Saudi Arabia. Deputy Ministry for Mineral Resources
1982, Report
An interagency report prepared by the U.S. Geological Survey Saudi Arabian Mission for the Ministry of Petroleum and Mineral Resources, Kingdom of Saudi Arabia. The work on which this report was based was performed in accordance with a cooperative agreement between the U.S. Geological Survey and the Ministry of Petroleum and...
Some observations on the ecology and fish management of reservoirs in the United States
N. G. Benson
1982, Canadian Water Resources Journal (7) 2-25
By 1980 there were 1,608 reservoirs (over 202 ha each) with a surface area of 4 million ha in the United States. Construction of new reservoirs has decreased in recent years because of the lack of suitable sites and the opposition of environmental interests. Reservoirs have characteristics of both lacustrine...
Biostratigraphy and paleoecology of lower Paleozoic, upper Cretaceous, and lower Tertiary rocks in U.S. Geological Survey New Madrid test wells, Southeastern Missouri
N. O. Frederiksen, Laurel M. Bybell, R. A. Christopher, A. J. Crone, L. E. Edwards, T. G. Gibson, J. E. Hazel, J.E. Repetski, D. P. Russ, C. C. Smith, L. W. Ward
1982, Tulane Studies in Geology and Paleontology (17) 23-45
The paleontology and biostratigraphy of Tertiary, Cretaceous, and Paleozoic rocks in the upper Mississippi embayment are incompletely known because marine fossils are only locally present in these rocks. This study concerns material from two U.S. Geological Survey test wells drilled in New Madrid County, southeastern Missouri, as part of earthquake...
Sensitivity of selected geomagnetic properties to truncation level of spherical harmonic expansions
E.R. Benton, Ronald H. Estes, R.A. Langel, L.A. Muth
1982, Geophysical Research Letters (9) 254-257
A two day selection of MAGSAT data is fit by spherical harmonic series truncated at increasing levels NF in the range 2<NF<14 to determine the extent to which the geomagnetic Gauss coefficients depend upon truncation level of the fit. The dependence is found to be concentrated in the range n<NF≲n+4...
Geologic hazards in Navarin Basin Province, Northern Bering Sea
Paul R. Carlson, Herman A. Karl, Jeffrey M. Fischer, Brian D. Edwards
1982, Conference Paper, Proceedings- Offshore Technology Conference
Navarin Basin, scheduled for leasing in 1984 (OCS sale 83), may contain vast accumulations of oil and gas. Several geologic and oceanographic processes that may be active in and around Navarin Basin province could be hazardous to commercial development. These potential hazards include submarine slides; sea-floor instability resulting from disturbance...
