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...

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...

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...
Nearshore phytoplankton of Hammond Bay, Lake Huron
Charles L. Brown, Bruce A. Manny
1983, Journal of Great Lakes Research (9) 523-529
To predict the effects of increased nutrient loading on nearshore phytoplankton populations in northern Lake Huron, we collected phytoplankton from a small, nearshore water intake at Hammond Bay four times per week from August 1973 to July 1975. Phytoplankton density, taxonomic composition, and biomass in the nearshore waters followed predictable,...
Population biology of yellow perch in southern Lake Michigan, 1971-79
LaRue Wells, Sherrell C. Jorgenson
1983, Technical Paper 109
This study was based mainly on gill-net collections of yellow perch (Perca flavescens) made during July and August 1971-79, in southern Lake Michigan at Grand Haven, Saugatuck, South Haven, Benton Harbor, and New Buffalo, Michigan; Michigan City and Gary, Indiana; Waukegan, Illinois; and Milwaukee, Wisconsin. Abundance of yellow perch was...
Channels and valleys on Mars
Mars Channel Working Group
1983, GSA Bulletin (94) 1035-1054
The discovery of channels, valleys, and related features of aqueous origin on Mars is of profound importance in comparative planetology. Models of the evolution of planetary surfaces and atmospheres must be reconciled with the diversity, abundance, and origins of channels and valleys on Mars. The term “channel” is properly restricted...

Atmospheric deposition: Sample handling, storage, and analytical procedures for chemical characterization of event-based samples in North Dakota
R. L. Houghton, Mary E. Berger, Nancy Zander, Sandra K. Dutchek
1983, Water-Resources Investigations Report 83-4205
The North Dakota atmospheric-deposition network uses HASL-type collectors to sample wet and dry deposition on an event basis for analysis of 8 principal mineral, 3 nutrient, and 15 trace constituents. Comparison of the compositions of wet deposition collected in adjacent collectors sampled on weekly and event bases indicates that weekly...

Talc in the suspended matter of the northwestern Atlantic
Lawrence J. Poppe, John C. Hathaway, Carol M. Parmenter
1983, Clays and Clay Minerals (31) 60-64
Knowledge of the distribution, concentration, and composition of suspended particulate matter in seawater is important to the understanding of sedimentation processes on the Continental Shelf. Because the surfaces of both organic and inorganic particles have high affinities for pollutants, such as certain trace metals, chlorinated hydrocarbons, and petroleum (Bothner et...
Furrowed outcrops of Eocene chalk on the lower continental slop offshore New Jersey
James M. Robb, John R. Kirby, John C. Hampson, Patricia R. Gibson, Barbara Hecker
1983, Geology (11) 182-186
A sea bottom of middle Eocene calcareous claystone cut by downslope-trending furrows was observed during an Alvin dive to the mouth of Berkeley Canyon on the continental slope off New Jersey. The furrows are 10 to 50 m apart, 4 to 13 m deep, linear, and nearly parallel in water depths of...
