Annual summary of ground-water conditions in Arizona, spring 1984 to spring 1985
Water Resources Division, U.S. Geological Survey
1986, Open-File Report 86-422-W
In arid and semiarid regions such as Arizona, the availability of adequate water supplies has a significant influence on the type and extent of economic development. About two-thirds of the water used in the State is groundwater. The nature and extent of the groundwater reservoirs must be known for proper...

Landslides
National Geophysical Data Center
1986, Report
The slopes above streams and rivers are subjected to a variety of processes that cause them to recede and retreat from the river or stream channel. These processes, collectively called mass wasting, can be classified according to rapidity of movement and according to the type of materials that are transported. Gravity is the...
On tide-induced Lagrangian residual current and residual transport: 1. Lagrangian residual current
Shizuo Feng, Ralph T. Cheng, Xi Pangen
1986, Water Resources Research (22) 1623-1634
Residual currents in tidal estuaries and coastal embayments have been recognized as fundamental factors which affect the long-term transport processes. It has been pointed out by previous studies that it is more relevant to use a Lagrangian mean velocity than an Eulerian mean velocity to determine the movements of water...
On tide-induced Lagrangian residual current and residual transport: 2. Residual transport with application in south San Francisco Bay, California
Shizuo Feng, Ralph T. Cheng, Xi Pangen
1986, Water Resources Research (22) 1635-1646
The transports of solutes and other tracers are fundamental to estuarine processes. The apparent transport mechanisms are convection by tidal current and current-induced shear effect dispersion for processes which take place in a time period of the order of a tidal cycle. However, as emphasis is shifted toward the effects...
Evaluation of Alaskan wetlands for waterfowl
Calvin J. Lensink, Dirk V. Derksen
1986, Conference Paper, Alaska: Regional wetland functions: Proceedings of a workshop held at Anchorage, Alaska, May 28-29, 1986
Few studies have focused specifically on use of Alaskan wetlands by waterfowl. However, substantial information on the values of wetlands is available from studies on individual species or that were conducted for other purposes. Most investigators have found it most effective to classify habitat use on the basis of observed...
Hydrology of carbonate aquifers in southwestern Linn County and adjacent parts of Benton, Iowa, and Johnson Counties, Iowa
Kenneth Wahl, Bill J. Bunker
1986, Water Supply Bulletin 15
Groundwater is the major source of water in Linn County and the surrounding area. Approximately 90 percent of the groundwater production is from Silurian, Devonian, and Quaternary aquifers. The Silurian and Devonian aquifers consist of limestone and dolomite with minor shale beds, which have a regional dip to the southwest of...
Geology and geochemistry of the Deer Trail Pb-Zn-Ag-Cu manto deposits, Marysvale District, west-central Utah
D.W. Beaty, C. G. Cunningham, R.O. Rye, T. A. Steven, E. Gonzalez- Urien
1986, Economic Geology (81) 1932-1952
Strata-bound sulphide replacement bodies in the Deer Trail mine are sinuous pipes in carbonate beds, approximately localized by an anticlinal axis, and radiate from a fault across the lower part of the Permian Toroweap formation. Indistinct sericitic envelopes provide a K/Ar age of 14 m.y., correlative with barren, altered volcanic...
Rock-water interaction in ash-flow tuffs (Yucca Mountain, Nevada, USA)- The record from uranium studies
Robert A. Zielinski, Charles A. Bush, R.W. Spengler, Barney J. Szabo
1986, Uranium (2) 361-386
Forty-eight core samples of ash-flow tuffs from Yucca Mountain, NV, were selected for comparative analysis by uranium-based methods to estimate past interaction with oxidizing water. Results aid in the selection of hydrologically isolated host rocks for radioactive waste disposal. U abundances were consistently more variable than thorium in whole rocks,...
Cobalt-rich ferromanganese crusts from the Central Pacific
James R. Hein, Frank T. Manheim, William C. Schwab
1986, Conference Paper, Proceedings of the Offshore Technology Conference
Ferromanganese crusts coat most hard substrates on seamounts, ridges, and plateaus in the centralPacific basin. Crusts from less than 2500 m water depth are rich in Mn, Co, Ni, Pb, and Pt. Samples we collected from the EEl of the Hawaiian, Johnston, Palmyra, and Marshall Islands are discussed. Necker Ridge...

Jon J. Major, B. Voight
1986, Journal of Sedimentary Petrology (691)
Three lahars that resulted from the flow transformation of an inflated pyroclastic surge caused by ejected lithic debris and hydrothermal water during the cataclysmic Mount St. Helens eruption of 18 May 1980 deposited about 1 x 106 m3 of massive, poorly sorted, poorly graded volcaniclastic sediment on the SW flank (SWF). Downflow changes in mean grain...
Organochlorine chemical residues in bluegills and common carp from the irrigated San Joaquin Valley floor, California
Michael K. Saiki, Christopher J. Schmitt
1986, Archives of Environmental Contamination and Toxicology (15) 357-366
Samples of bluegills (Lepomis macrochirus) and common carp (Cyprinus carpio) collected from the San Joaquin River and two tributaries (Merced River and Salt Slough) in California were analyzed for 21 organochlorine chemical residues by gas chromatography to determine if pesticide contamination was confined to downstream sites...
Use of the instream flow incremental methodology: a tool for negotiation
Mary G. Cavendish, Margaret I. Duncan
1986, Environmental Impact Assessment Review (6) 347-363
The resolution of conflicts arising from differing values and water uses requires technical information and negotiating skills. This article outlines the Instream Flow Incremental Methodology (IFIM), developed by the US Fish and Wildlife Service, and demonstrates that its use to quantify flows necessary to protect desired instream values aids negotiation...
Mississippi embayment aquifer system in Mississippi: Geohydrologic data compilation for flow model simulation
J. K. Arthur, R.E. Taylor
1986, Journal of the American Water Resources Association (22) 1021-1029
As part of the Gulf Coast Regional Aquifer System Analysis (GC RASA) study, data from 184 geophysical well logs were used to define the geohydrologic framework of the Mississippi embayment aquifer system in Mississippi for flow model simulation. Five major aquifers of Eocene and Paleocene age were defined within this...

K. B. Davis, C. A. Goudie, B.A. Simco, R. MacGregor III, N. C. Parker
1986, Ecological and Evolutionary Physiology (59) 717-724
Blinded, pinealectomized, or blinded and pinealectomized female channel catfish (Ictalurus punctatus) were placed with normal (unoperated on) control fish in outdoor tanks at constant temperature (21 ± 2 C) or earthen ponds (ambient conditions) in February or August, when they were 21 or 27 mo old. Fish were sampled through...
Holocene depositional history of a large glaciated estuary, Penobscot Bay, Maine
Harley J. Knebel
1986, Marine Geology (73) 215-236
Data from seismic-reflection profiles, sidescan sonar images, and sediment samples reveal the Holocene depositional history of the large (1100 km2) glaciated Penobscot Bay estuary of coastal Maine. Previous work has shown that the late Wisconsinan ice sheet retreated from the three main passages of the bay between 12,700 and 13,500...
Field comparison of shallow seismic sources
R. D. Miller, S. E. Pullan, J.S. Waldner, F.P. Haeni
1986, Geophysics (51) 2067-2092
Choosing a seismic source for a shallow reflection survey can be the most pivotal decision for the engineering geophysicist. The intent of this paper is to present data that will assist in selection of a shallow seismic source best meeting the goals within the constraints of specific projects, particularly in...
