Distribution and biology of Indo-Pacific insular hypogeal shrimps
J. A. Maciolek
1983, Bulletin of Marine Science (33) 606-618
Ten species of caridean shrimps, representing nine genera in five families, have been found in exposures of the marine water table at 28 islands from Hawaii to the western Indian Ocean. Synthesis of literature information and personal observations indicate that, as a group, these shrimps are characterized by red body...
The sky's the limit!
United States Geological Survey
1983, Report
The National High Altitude Photography Program NHAP-The National High Altitude Photography program- is making recent aerial photographs, both black-and-white and color infrared, more easily accessible to you. Designed to help you acquire high altitude photographs quickly and efficiently, NHAP can help you save valuable research time as well as help: -Improve your...
Ground-water resources and geology of Dodge County, Wisconsin
R.W. DeVaul, C.A. Harr, J.J. Schiller
1983, Wisconsin Geological & Natural History Survey Information Circular 44
The ground-water resources of Dodge County were evaluated to aid planners in meeting the needs resulting from growth in population and industry. The sand-and-gravel, Silurian dolomite, Galena-Platteville, and sandstone aquifers are the principal sources of ground water. Probable well yields from the sand- and-gravel aquifer and the Galena-Platteville aquifer range...
Trends in ground-water levels in Wisconsin through 1981
R.M. Erickson, R. D. Cotter
1983, Wisconsin Geological & Natural History Survey Information Circular 43
Hydrographs of ground-water levels in Wisconsin display fluctuations in the potentiometric surface of confined and unconfined aquifers. The graphs are plotted from periodic (weekly or monthly) measurements and from continuous recording gage records. Two hundred and ten hydrographs having periods of record of at least 5 years between 1934 and...
Geohydrologic framework of the Roswell ground-water basin, Chaves and Eddy Counties, New Mexico
G. E. Welder
1983, Technical Report 42
This report describes the geohydrology of the Roswell ground-water basin and shows the long-term hydrostatic-head changes in the aquifers. The Roswell ground-water basin consists of a carbonate artesian aquifer overlain by a leaky confining bed, which, in turn is overlain by an alluvial water-table aquifer. The water-table aquifer is hydraulically...
Reconnaissance of ground water in vicinity of Wichita Mountains southwestern Oklahoma
John S. Havens
1983, Circular 85
Urbanization and industrial growth have increased demands on water supplies in the vicinity of the Wichita Mountains in southwestern Oklahoma. The principal city, Lawton, uses surface water, supplemented by small quantities of ground water from the Arbuckle Group (Cambrian-Ordovician), for industrial and recreational use. During periods of drought, surface-water supplies...
Reconnaissance of the quality of surface water in the Weber River basin, Utah
Kendall R. Thompson
1983, Technical Publication 76
This report on the reconnaissance of surface-water quality in the Weber River basin was prepared by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights. The purposes of the reconnaissance were: (1) To obtain information on the general inorganic chemical characteristics of...
Multiwavelength EDM measurements in southern California
Larry E. Slater, Art McGarr, John O. Langbein, Mark F. Linker
1983, Tectonophysics (97) 39-39
We installed a precise geodetic network along the San Andreas fault near Pearblossom, California in November, 1980. The network is within the region frequently referred to as the "Palmdale Uplift" and consists of 13 lines radiating from a central benchmark. The lines range in length from 3.2 to 8.1 km...
Land use and land cover digital data
Robin G. Fegeas, Robert W. Claire, Stephen C. Guptill, K. Eric Anderson, Cheryl A. Hallam
1983, Open-File Report 82-22
The discipline of cartography is undergoing a number of profound changesthat center on the emerging influence ofdigital manipulation and analysis ofdata for the preparation of cartographic materials and for use in geographic information systems. Operational requirements have led to the development by the USGS National Mapping Division of several documents...
Additions of nutrients and major ions by the atmosphere and tributaries to nearshore waters of northwestern Lake Huron
Bruce A. Manny, R.W. Owens
1983, Journal of Great Lakes Research (9) 403-420
Nutrient additions by the atmosphere and six tributaries to nearshore waters of northwestern Lake Huron were measured at weekly intervals from August 1975 to July 1976. The atmosphere contributed 43% of the nitrogen (N) and 10% of the phosphorus (P) that was added during the year. The 1975–76 atmospheric loading...
Nest sites and eggs of Kittlitz's and Marbled murrelets
Robert H. Day, Karen L. Oakley, D.R. Barnard
1983, Condor (85) 265-273
Fourteen known and three probable nests of Kittlitz's Murrelet (Brachyramphus brevirostris) and eight known and one probable nest of Marbled Murrelet (B. marmoratus) have been reported. Nests of Kittlitz's Murrelet tend to be at higher elevations and farther inland than those of Marbled Murrelet. Kittlitz's nests have much less vegetative...
13C NMR spectral characterization of epimeric rotenone and some related tetrahydrobenzopyranofurobenzopyranones
S. L. Abidi, M.S. Abidi
1983, Journal of Heterocyclic Chemistry (20) 1687-1692
The 13C nuclear magnetic resonance (nmr) spectra of epimers of rotenone and four 12a-hydroxy-analogues were examined to determine the stereochemical effect of the B/C ring fusion involving the 6a- and 12a-carbon centers. Chemical shift differences between the epimeric carbon resonances of cis- and trans-6a,12a-compounds were notably larger than those of...
High-performance liquid chromatography of quinoidal imminium compounds derived from triphenylmethanes
S. L. Abidi
1983, Journal of Chromatography (255) 101-114
A series of eleven p-aminotriphenylmethane dyes have been studied by high-performance liquid chromatography (HPLC). The combined use of HPLC and spectrophotometry permits specific detection of these compounds in the visible range around 600 nm. As the high affinity of the imminium cations for the active sites of the hydrocarbonaceous stationary...
