Richard L. Johnson, Austin K. Andrews, Gregor T.L. Auble, Richard A. Ellison, David B. Hamilton, James E. Roelle, Peter J. McNamee
1983, Report
The U.S. Environmental Protection Agency (EPA) needs a comprehensive method to evaluate the human health and environmental effects of alternative agricultural pest management strategies. This project explored the utility of Adaptive Environmental Assessment (AEA) techniques for meeting this need. The project objectives were to produce models for environmental...
Groundwater observation network design for the Kansas groundwater management districts, U.S.A.
M. Sophocleous
1983, Journal of Hydrology (61) 371-389
Concerns about the efficiency and economic soundness of the Kansas groundwater monitoring program led to a systematic redesign of this network, a tentative phase of which is presented in this study. The objectives of this paper include monitoring of major aquifers within each groundwater management district at a spatially more...
Distribution of larval fishes related to potential navigation impacts on the upper Mississippi River, pool 7
L. E. Holland, J.R. Sylvester
1983, Transactions of the American Fisheries Society (112) 293-301
Ichthyoplankton samples were collected twice monthly during spring and summer 1981 from a variety of habitats in Navigation Pool 7 of the upper Mississippi River. Larval‐fish distributions in the pool and variations in those distributions were analyzed relative to potential impacts of increased commercial navigation. Although as...
Upper Cenozoic silicoflagellates from offshore Ecuador, Deep Sea Drilling Project Site 504
David Bukry
1983, Initial Reports of the D.S.D.P. (69) 321-342
Diverse and abundant late Miocene to Pleistocene silicoflagellates at DSDP Site 504 can be correlated by tropical biostratigraphic zones and relative paleotemperature values to eastern tropical Pacific reference site DSDP 503A farther to the west. Early Pliocene assemblages, which were poorly known until now, are present and can be correlated...
Pressure core barrel; application to the study of gas hydrates, Deep Sea Drilling Project Site 533, Leg 76
Keith A. Kvenvolden, D. Cameron
1983, Initial Reports of the D.S.D.P. (76) 367-375
A pressure core barrel (PCB), developed by the Deep Sea Drilling Project, was used successfully to recover, at in situ pressure, sediments of the Blake Outer Ridge, offshore the southeastern United States. The PCB is a unique, wire-line tool, 10.4 m long, capable of recovering 5.8 m of core (5.8...
Concentrations and carbon isotopic compositions of CH4 and CO2 in gas from sediments of the Blake Outer Ridge, Deep Sea Drilling Project Leg 76
E.M. Galimov, Keith A. Kvenvolden
1983, Initial Reports of the D.S.D.P. (76) 403-407
The principal gaseous carbon-containing components identified in the first 400 m of sediment at Deep Sea Drilling Project Site 533, Leg 76, are methane (CH4 ) and carbon dioxide (CO2 ). Below a sub-bottom depth of about 25 m, sedi ment cores commonly contained pockets caused by the expansion of...

Henry L. Short
1983, Report
This report summarizes information produced from Interagency Agreement No. AA-851-IA1-27 between the Bureau of Land Management (BLM), USDI, and the Fish and Wildlife Service (FWS), USDI. The contract was instrumental in the final development of wildlife guilds for the Hualapai-Aquarius planning area of the BLM in westcentral Arizona, reported...

A system for measuring bottom profile, waves and currents in the high-energy nearshore environment
Asbury H. Sallenger Jr., P.C. Howard, C.H. Fletcher III, P.A. Howd
1983, Marine Geology (51) 63-76
A new data-acquisition system capable of measuring waves, currents and the nearshore profile in breaking waves as high as 5 m has been developed and successfully field-tested. Components of the mechanical system are a sled carrying a vertical mast, a double-drum winch placed landward of the beach, and a line...
Hydrostratigraphic subdivisions and fault barriers of the Edwards aquifer, south-central Texas, U.S.A.
R.W. Maclay, T. A. Small
1983, Journal of Hydrology (61) 127-146
The karstic Edwards Limestone within the Balcones Fault Zone of south-central Texas forms a productive confined aquifer that consists predominately of dense carbonate rocks and contains several layers of highly permeable and porous honeycombed rocks that have been produced by the leaching of evaporitic, tidal flat or reefal deposits. Fractures...
Relation of concealed faults to water quality and the formation of solution features in the Floridan aquifer, northeastern Florida, U.S.A.
G.W. Leve
1983, Journal of Hydrology (61) 251-264
Geological and hydrological information on the Floridan aquifer in northeastern Florida indicates that isolated occurrences of water having relatively high chloride concentration in the upper part of the aquifer may be associated with buried faults. Water having chloride concentrations of more than 700 mg l−1 occurs in the deeper zone of...

Experimental deformation of polycrystalline H2O ice at high pressure and low temperature: Preliminary results
W.B. Durham, H. C. Heard, Stephen H. Kirby
1983, Journal of Geophysical Research B: Solid Earth (88) B377-B392
Interest in the mechanical properties of water ice under the conditions in which it exists in the outer solar system has motivated the development and use of a new high‐pressure, low‐temperature triaxial deformation apparatus. Constant displacement rate tests on 70 samples of pure polycrystalline water ice have been performed at...

Temperature and precipitation estimates through the last glacial cycle from Clear Lake, California, pollen data
D.P. Adam, G. James West
1983, Science (219) 168-170
Modern pollen surface samples from six lake and marsh sites in the northern California Coast Ranges establish a linear relation between elevation and the oak/(oak + pine) pollen ratio. Modern temperature and precipitation lapse rates were used to convert variations in the pollen ratio into temperature and...
Geologic evolution of Hess Rise, central North Pacific Ocean
T. L. Vallier, Walter E. Dean, David K. Rea, Jorn Thiede
1983, GSA Bulletin (94) 1289-1307
Cores from four Deep Sea Drilling Project (DSDP) sites (310, 464, 465, and 466) and seismic-reflection profiles provide data that are used to interpret the geological evolution and paleoenvironments of Hess Rise, a prominent oceanic plateau in the central North Pacific Ocean. Hess Rise apparently formed in the Southern Hemisphere...
The chemical composition of lakes in the north‐central United States
Eville Gorham, Walter E. Dean, J.E. Sanger
1983, Limnology and Oceanography (28) 287-301
Lake waters of the north‐central U.S.A. are classified into five groups, based on increasing specific conductivity and changes in ionic composition from east to west, from Wisconsin through Minnesota to North and South Dakota. The most dilute group of waters has specific conductivities <29 µmhos · cm−1 at 25°C; the most concentrated...
Tectonic evolution of Gulf of Anadyr and formation of Anadyr and Navarin basins
Michael S. Marlow, Alan K. Cooper, Jonathan R. Childs
1983, AAPG Bulletin (67) 646-665
New seismic reflectionand refraction data reveal that Anadyr basin is separated from Navarin basin by Anadyr ridge, a southeast-northwest-trending bedrock high that is characterized by high-amplitude, short-wavelength magnetic anomalies. Anadyr ridge may be an offshore extension of the melange belt underlying the Koryak Range. Sonobuoy refraction data indicate that the...
Wandering terranes in southern Alaska: The Aleutia Microplate and implications for the Bering Sea
Michael S. Marlow, Alan K. Cooper
1983, Journal of Geophysical Research B: Solid Earth (88) 3439-3446
Paleomagnetic and geological data suggest that much of southern Alaska is a collage of tectonostratigraphic terranes which originated in Mesozoic time at paleolatitudes far south of their present position. The time of ‘docking’ of the terranes against cratonic Alaska is critical to defining their amalgamated size and extent during their...
