Population ecology of the mallard: II. Breeding habitat conditions, size of the breeding populations, and production indices
Richard S. Pospahala, David R. Anderson, Charles J. Henny
1974, Resource Publication 115
This report, the second in a series on a comprehensive analysis of mallard population data, provides information on mallard breeding habitat, the size and distribution of breeding populations, and indices to production. The information in this report is primarily the result of large-scale aerial surveys conducted during May and July,...
Optical data processing and projected applications of the ERTS-1 imagery covering the 1973 Mississippi River Valley floods
Morris Deutsch, Fred Ruggles
1974, Water Resources Bulletin (10) 1023-1039
Flooding along the Mississippi River and some of its tributaries was detected by the multispectral scanner (MSS) on the Earth Resources Technology Satellite (ERTS-1) on at least three orbits during the spring of 1973. The ERTS data provided the first opportunity for mapping the regional extent of flooding at the...
Survey of remote sensing applications
Morris Deutsch
1974, Water Well Journal (28) 35-38
Data from the first earth resources technology satellite (ERTS) as well as from NASA and other aircraft, contain much of the information indicative of the distribution of groundwater and the extent of its utilization. Thermal infrared imagery from aircraft is particularly valuable in studying groundwater discharge to the sea and...
EROS: A space program for Earth resources
Water Resources Division, U.S. Geological Survey
1974, Report
The EROS Program, administered by the U. S. Geological Survey, works with representatives of departmental bureaus and offices to coordinate research and application of remote-sensing technology to the day to-day operations of the department. Most of the research and applications have been made possible by the experimental data acquisition systems...
Strain-gage measurements in Carlsbad Caverns, New Mexico
J. S. McLean
1974, Journal of Research of the U.S. Geological Survey (3) 281-283
Displacement transducers installed on a near-vertical joint in the lunchroom in Carlsbad Caverns measured small movements along the joint with a resolution of 3.7X 10-6 in (9.4X10-6 cm). During 1973 the maximum annual displacement horizontally, vertically, and perpendicularly to the plane of the joint was 4.7X10-4, 4.0X10-4, and 1.1X10-4 in...
Preliminary findings of a leachate study on two landfills in Suffolk County, New York
Grant E. Kimmel, Olin C. Braids
1974, Journal of Research of the U.S. Geological Survey (3) 273-280
Plumes of leachate-enriched ground water extend 10,600 and 5,000 ft (3,200 and 1,500 m) downgradient from landfills in the towns of Babylon and Islip, respectively, and extend vertically beneath the landfills to the base of the upper glacial aquifer, whose thickness ranges from 71 to 77 ft (22-24 m) at...
Upward migration of deep-well waste injection fluids in Floridan Aquifer, south Florida
M. I. Kaufman, D.J. McKenzie
1974, Journal of Research of the U.S. Geological Survey (3) 261-271
Geochemical data from an industrial deep-well waste injection system southeast of Lake Okeechobee indicate a decrease in sulfate concentration concomitant with an increase in hydrogen sulfide concentration, a result of oxidation of injected organic waste by anaerobic bacteria. Subtle decreases in the sulfate-chloride ratio suggest that the waste migrated upward...
Geometry and growth of the White Sands dune field, New Mexico
Edwin D. McKee, Richard J. Moiola
1974, Journal of Research of the U.S. Geological Survey (3) 59-66
Recent studies of the cores from four drill holes at the White Sands dune field in New Mexico demonstrated that the eolian sand body below the present active dunes ranges in thickness from 23 to 34 ft in the area tested. It consists of one to two older generations of...
Stratigraphic relationships within the Baraga Group of Precambrian age, central Upper Peninsula, Michigan
W.F. Cannon, John S. Klasner
1974, Journal of Research of the U.S. Geological Survey (3) 47-51
Details of the stratigraphic section in parts of northern Michigan have been known for many years, but correlation of units between geographically separated areas has been partly speculative. Mapping in the Witch Lake quadrangle has filled the gap between well-studied areas of the Marquette trough and parts of Iron and...
Chemical analyses of Red Sea sediments
Frank T. Manheim, David E. Siems
1974, Initial reports of the Deep Sea Drilling Project (23) 923-938
One of the prime motives for exploring the deeper subsurface sediments of the Red Sea floor was to gain information on the geochemical systems controlling the hot brine-metalliferous deposits. Accordingly, a strong effort was made to provide both shipboard and laboratory means of analysis of the recovered phases. Shipboard spectrographic...
Red Sea geochemistry
Frank T. Manheim
1974, Initial reports of the Deep Sea Drilling Project (23) 975-998
The Red Sea drillings reveal a number of new facets of the hot-brine-metalliferous system and other geochemical aspects of the sea, its sediments, and its past history as follows: 1) Dark shales rich in organic material, and containing enhanced Mo and V concentrations, are characteristic of Plio-Pleistocene strata in the...
Ultramafic rocks of the Eagle quadrangle, east-central Alaska
Helen L. Foster, Terry E.C. Keith
1974, Journal of Research of the U.S. Geological Survey (2) 657-669
More than 97 separate occurrences of ultramafic rocks, some of which are included in a north west-trending zone of alpine-type ultramafic rocks, have been mapped in the Eagle quadrangle, east-central Alaska. They are divided into three groups primarily on the basis of degree of serpentinization. Group I consists of lens-shaped bodies...
Optical and X-ray crystallographic investigations of strontioginorites
Ralph P. Christian, G. Donald Eberlein, Judith A. Konnert
1974, Journal of Research of the U.S. Geological Survey (2) 699-700
Compositional, optical, and unit-cell data are presented for a suite of strontioginorites. These crystals show that Sr:Ca ≈ 1 is preferred. Lack of variation in the Sr:Ca resulted in no meaningful correlation between composition and physical properties....
Origin of spongy cherts
Beth M. Madsen
1974, Journal of Research of the U.S. Geological Survey (2) 685-687
The spongy-textured surface in some cherts, visible on electron micrographs, is inherited from authigenic cristobalite. Spongy bedded cherts were originally bedded porcelanites similar to the porcelanite in the Miocene Monterey Formation of California....
