Automated determination of bromide in waters by ion chromatography with an amperometric detector
G. S. Pyen, D. E. Erdmann
1983, Analytica Chimica Acta (149) 355-358
An automated ion chromatograph, including a program controller, an automatic sampler, an integrator, and an amperometric detector, was used to develop a procedure for the determination of bromide in rain water and many ground waters. Approximately 10 min is required to obtain a chromatogram. The detection limit for bromide is...
Solubility relations in the ternary system NaCl-CsCl-H2O at 1 atm. 1. Solubilities of halite from 20 to 100 °C
I.-M. Chou, R.D. Lee
1983, Journal of Chemical and Engineering Data (28) 390-393
Solubilities of halite in the ternary system NaCl-CsCl-H2O have been determined by the visual polythermal method at 1 atm from 20 to 100 °C along five constant CsCl/(CsCl + H2O) weight ratio lines. These five constant weight ratios are 0.1, 0.2, 0.3, 0.4, and 0.5. The maximum uncertainties in these...

Synthesis of geophysical data with space-acquired imagery: a review
David A. Hastings
1983, Advances in Space Research (3) 157-168
Geophysical data obtained from ground and airborne platforms have been used in the development of regional geologic models for many years. Space-acquired data and imagery have a shorter but similar history of applications. All these data may be synthesized either manually or digitally. Manual synthesis methods consist of overlaying and...
Land application of wastewater and its effect on ground-water quality in the Livermore-Amador Valley, Alameda County, California
M. A. Sylvester
1983, Water-Resources Investigations Report 82-4100
Ground-water quality, ground-water level, and rainfall data collected during the 1975 water year through the 1980 water year were analyzed to determine the effects of land application of effluent from wastewater treatment plants on ground-water quality in the Livermore-Amador Valley. Annual rainfall varied markedly during the study: 1976 and 1977...

Crustal structure beneath the southern Appalachians: Nonuniqueness of gravity modeling
Deborah R. Hutchinson, John A. Grow, Kim D. Klitgord
1983, Geology (11) 611-615
Gravity models computed for a profile across the long-wavelength paired negative-positive Bouguer anomalies of the southern Appalachian Mountains show that the large negative anomaly can be explained by a crustal root zone, whereas the steep gradient and positive anomaly east of the root may be explained equally well by three...

A Canada goose project in Connecticut
Kathryn A. Converse
1983, The Connecticut Warbler (1) 36-38
It wasn't so long ago that the wild cries of Canada geese overhead were enough to draw most people out of their homes to look skyward. It was a rare sound heard only in the spring and fall when migrating flocks of these magnificent birds marked the change of the...
Assessment of water quality in canals of eastern Broward County, Florida, 1969-74
Bradley G. Waller, Wesley L. Miller
1982, Water-Resources Investigations Report 82-3
An intensive water-quality monitoring program was started in 1969 to determine the effects of man-induced contaminants on the water quality in the primary canal system of eastern Broward County, Florida. This report covers the first 6 years of the program and provides a data base that can be used to...
Effects of land use on ground-water quality in the East Everglades, Dade County, Florida
B.G. Waller
1982, Water-Resources Investigations Report 82-4093
Groundwater quality characteristics of the Biscayne aquifer from September 1978 through June 1979 were determined for seven land use areas within the East Everglades in Dade County, Florida. Four agricultural areas, two low-density residential areas, and Chekika Hammock State Park were investigated. The effects of land use on the groundwater...
Effects of land use on surface-water quality in the East Everglades, Dade County, Florida
Bradley G. Waller
1982, Water-Resources Investigations Report 81-59
Water-quality characteristics were determined at five developed areas in the East Everglades, Dade County, Florida, during the 1978 wet season (June through October). These areas are designated as: Coopertown; Chekika Hammock State Park; residential area; rock-plowed tomato field; and Cracker Jack Slough agricultural area. Data from the developed areas were...
Areal extent of a plume of mineralized water from a flowing artesian well in Dade County, Florida
Bradley G. Waller
1982, Water-Resources Investigations Report 82-20
A flowing artesian well that taps the Floridan aquifer at Chekika Hammock State Park is contaminating the overlying Biscayne aquifer with saline water. The plume of mineralized water extends approximately 7 miles southeast of the well and ranges in width from 1 to 2 miles. The areal extent of contamination...

Measurement and computation of streamflow
Saul Edward Rantz
1982, Water Supply Paper 2175
The purpose of this manual is to provide a comprehensive description of state-of-the-art standardized stream-gaging procedures, within the scope described below. The manual is intended for use as a training guide and reference text, primarily for hydraulic engineers and technicians in the U.S. Geological Survey, but the manual is also...
Reconnaissance geochemical studies in the Bristol Bay, Ugashik, and Karluk quadrangles, Alaska: A section in The United States Geological Survey in Alaska: Accomplishments during 1980

1982, Circular 844
Geochemical reconnaissance studies in the Bristol Bay, Ugashik, and Karluk quadrangles were completed with collection and analyses of more than 1,200 stream-sediment and heavy mineral-concentrate samples during 1979 and 1980. At least two areas of possible metallic mineral occurrence have been delineated by results of the analyses, geologic fieldwork, and...

1982, Circular 844
The recently completed aeromagnetic survey of the Chignik and Sutwik Island quadrangles, on the Alaska Peninsula, is one of the most detailed systematic surveys ever made across a modern "volcanic arc" setting where both Holocene volcanic edifices and older volcanic centers occur (fig. 54)....
Preliminary results of potassium-argon age determinations from the Ugashik quadrangle, Alaska Peninsula: A section in The United States Geological Survey in Alaska: Accomplishments during 1980
Frederic H. Wilson, Nora B. Shew
1982, Circular 844
Early and preliminary results of potassiumargon dating work on samples from 12 sites in the Ugashik quadrangle indicate a continuation of the geologic trends seen in the Chignik and Sutwik Island quadrangles to the south (Wilson, 1980). Tertiary volcanic and hypabyssal rocks apparently fall into two age groups: early Tertiary-late...
Apparent episodicity of magmatic activity based on radiometric age determination: A section in The United States Geological Survey in Alaska: Accomplishments during 1980
Frederic H. Wilson, Nora B. Shew
1982, Circular 844
Results of recent potassium-argon age studies in the Chignik region, Alaska, (Wilson, 1980; Wilson and others, 1982) have suggested a distinct episodicity in igneous activity during Tertiary time. To date work on the Aleutian magmatic arc indicates that plutonic activity took place along the present outer Pacific margin and in...

Magnitude and intensity: Measures of earthquake size and severity
Henry Spall, editor(s)
1982, Earthquake Information Bulletin (USGS) (14) 209-219
Earthquakes can be measured in terms of either the amount of energy they release (magnitude) or the degree of ground shaking they cause at a particular locality (intensity). Although magnitude and intensity are basically different measures of an earthquake, they are frequently confused by the public and new reports of...
