Black duck population units as determined by patterns of band recovery
G.W. Pendleton, J.R. Sauer
D.R. McCullough, R.H. Barrett, editor(s)
1992, Book chapter, Wildlife 2001: Populations.
To estimate regional survival and band recovery rates for waterfowl populations, banding sites must be grouped for data analysis. We group American black duck banding sites using cluster analysis of pairwise comparisons of the distributions of band recoveries. We propose 6 population units, substantially fewer than the 27 black duck...
Forum on land use and land Cover: Summary report
U.S. Environmental Protection Agency, Water Resources Division, U.S. Geological Survey
1992, Book
This report includes the agenda and abstracts of presentations from the Forum on Land Use and Land Cover Data, cohosted by the U. S. Geological Survey (USGS) and the U.S. Environmental Protection Agency (USEPA), February 25-27,1992 at the USGS National Center in Reston, Virginia. The Forum was conducted under the...
Increasing rates of atmospheric mercury deposition in midcontinental North America
Edward B. Swain, Daniel R. Engstrom, Mark E. Brigham, Thomas A. Henning, P.L. Brezonik
1992, Science (257) 784-787
Mercury contamination of remote lakes has been attributed to increasing deposition of atmospheric mercury, yet historic deposition rates and inputs from terrestrial sources are essentially unknown. Sediments of seven headwater lakes in Minnesota and Wisconsin were used to reconstruct regional modern and preindustrial deposition rates of mercury. Whole-basin mercury fluxes,...
Groundwater dolocretes from the Upper Triassic of the Paris Basin, France: A case study of an arid, continental diagenetic facies
C. Spotl, V.P. Wright
1992, Sedimentology (39) 1119-1136
Thick dolomite-cemented horizons (dolocretes) occur within a fluvial sandstone-mudstone sequence of Late Triassic age in the western part of the Paris Basin, France. Two types of dolomites can be distinguished: (a) nodular dolomitic beds less than a few metres thick, which formed within mottled overbank siltstones and mudstones; and (b)...
Palaeoecology and sedimentology of the dysaerobic Bedford fauna (late Devonian), Ohio and Kentucky (USA)
J.C. Pashin, F.R. Ettensohn
1992, Palaeogeography, Palaeoclimatology, Palaeoecology (91) 21-34
Oxygen-deficient biofacies models rely on lithologic and paleontologic attributes to identify distinctive biofacies interpreted to reflect levels of oxygenation in anaerobic, dysaerobic, and aerobic parts of a stratified water column. This study of the Bedford fauna from the Bedford Shale of Ohio and Kentucky and from adjacent black-shale units reports...
Transgressive channel filling in the Breathitt Formation (Upper Carboniferous), Eastern Kentucky Coal Field, USA
S.F. Greb, D.R. Chesnut Jr.
1992, Sedimentary Geology (75) 209-221
Carbonaceous shales of brackish or marine origin in the Breathitt Formation may exhibit sharp bases with local channel-form scours. Minor channels at the bases of these shales exhibit three general types of fill: (1) shale, (2) bioturbated, heterolithic strata, and (3) coal overlain by shale or bioturbated, heterolithic strata. Most...
A-type granite and the Red Sea opening
Robert G. Coleman, Susan DeBari, Zell E. Peterman
1992, Tectonophysics (204) 27-40
Miocene-Oligocene A-type granite intrudes the eastern side of the Red Sea margin within the zone of extension from Jiddah, Saudi Arabia south to Yemen. The intrusions developed in the early stages of continental extension as Arabia began to move slowly away from Africa (around 30–20 Ma). Within the narrow zone...
Geology of the d'Entrecasteaux-New Hebrides arc collision zone: Results from a deep submersible survey
J.-Y. Collot, S. Lallemand, B. Pelletier, J.-P. Bissen, G. Glacon, M. A. Fisher, H. Gary Greene, J. Boulin, J. Daniel, M. Monzier
1992, Tectonophysics (212) 213-241
During the SUBPSO1 cruise, seven submersible dives were conducted between water depths of 5350 and 900 m over the collision zone between the New Hebrides island arc and the d'Entrecasteaux Zone (DEZ). The DEZ, a topographic high on the Australian plate, encompasses...
Water Resources Data, New Mexico, Water Year 1991
J.P. Borland, R.K. DeWees, R.L. McCracken, R.L. Lepp, D. Ortiz
1992, Water Data Report NM-91-1
Water-resources data for the 1991 water year for New Mexico consist of records of discharge and water quality of streams; stage, contents and water quality of lakes and reservoirs; and water levels and water quality in wells and springs. This report contains discharge records for-183 gaging stations; stage and contents...
Configuration of the base of the Edwards-Trinity aquifer system and hydrogeology of the underlying pre-Cretaceous rocks, west-central Texas
Rene A. Barker, Ann F. Ardis
1992, Water-Resources Investigations Report 91-4071
The Edwards-Trinity aquifer system is underlain by an extensive complex of rocks, ranging from Late Cambrian through Late Triassic in age, that are typically about 10 to perhaps 1,000 times less permeable than those composing the aquifer system. The Cretaceous rocks of the aquifer system are separated from the pre-Cretaceous...
Geohydrology and simulated ground-water flow, Plymouth-Carver aquifer, southeastern Massachusetts
Bruce P. Hansen, Wayne W. Lapham
1992, Water-Resources Investigations Report 90-4204
The Plymouth-Carver aquifer underlies an area of 140 square miles and is the second largest aquifer in areal extent in Massachusetts. It is composed primarily of saturated glacial sand and gravel. The water-table and bedrock surface were mapped and used to determine saturated thickness of the aquifer, which ranged from...
Deserts: Geology and resources
Alta S. Walker
1992, Report
Approximately one-third of the Earth's land surface is desert, arid land with meager rainfall that supports only sparse vegetation and a limited population of people and animals. Deserts stark, sometimes mysterious worlds have been portrayed as fascinating environments of adventure and exploration from narratives such as that of Lawrence of...
