Hydrogeology of the western part of the Salt River Valley area, Maricopa County, Arizona
James G. Brown, D. R. Pool
1989, Water-Resources Investigations Report 88-4202
The Salt River Valley is a major population and agricultural center of more than 3,000 mi2 in central Arizona (fig. 1). The western part of the Salt River Valley area (area of this report) covers about 1,500 mi2. The Phoenix metropolitan area with a population of more than 1.6 million...
Distribution, facies, ages, and proposed tectonic associations of regionally metamorphosed rocks in northern Alaska
Cynthia Dusel-Bacon, William Peters Brosge, Alison B. Till, Elizabeth O. Doyle, Charles F. Mayfield, Hillard N. Reiser, Thomas P. Miller
1989, Professional Paper 1497-A
Approximately half of the exposed bedrock in northern Alaska has been regionally metamorphosed. The most widespread metamorphic episode that affected northern Alaska occurred under low-grade, initially high-pressure (blueschist-facies) conditions during Mesozoic time. This episode is thought to have been related to the obduction of one or more oceanic terranes onto...

Map showing late Quaternary faults and 1978-84 seismicity of the Los Angeles region, California
Joseph I. Ziony, Lucile M. Jones
1989, Miscellaneous Field Studies Map 1964
The Los Angeles region of California faces the greatest seismic risk of any part of the United States. The region is inhabited by more than 11 million people and is one of the Nation's key commercial and industrial centers. It lies astride a web of potentially active faults, including those...

Vertical surface displacements along a part of the Newport-Inglewood zone of folds and faults, Los Angeles and Orange Counties, California
Robert O. Castle, Jane M. Buchanan-Banks
1989, Miscellaneous Field Studies Map 2088
During the past half century, the onshore section of the Newport- Inglewood zone of folds and faults between the Dominguez oil field and Corona del Mar (fig. 1) has been repeatedly leveled to geodetic standards. These essentially fortuitous surveys are unrelated to either the tectonic framework or the urbanization...

The influence of north Pacific atmospheric circulation on streamflow in the west
Daniel R. Cayan, David H. Peterson
1989, Book chapter, Aspects of climate variability in the Pacific and the western Americas
The annual cycle and nonseasonal variability of streamflow over western North America and Hawaii is studied in terms of atmospheric forcing elements. This study uses several decades of monthly average streamflow beginning as early as the late 1800's over a network of 38 stations. In addition to a strong...

Tectonostratigraphic terranes and their Paleozoic boundaries in the central and southern Appalachians
J. Wright Horton, Jr., A.A. Drake, D.W. Rankin
1989, Geological Society of America Special Papers (230) 213-245
Parts of the central and southern Appalachian orogen appear to have evolved away from Proterozoic North America (Laurentia) and to have been accreted to it during the Paleozoic orogenies that collectively formed the orogen. Identifying each tectonostratigraphic terrane is a necessary step in understanding the evolution of the orogen. The terranes in the central and southern Appalachians are...
Extensional faulting in the southern Klamath Mountains, California
R.A. Schweickert, W. P. Irwin
1989, Tectonics (8) 135-149
Large northeast striking normal faults in the southern Klamath Mountains may indicate that substantial crustal extension occurred during Tertiary time. Some of these faults form grabens in the Jurassic and older bedrock of the province. The grabens contain continental Oligocene or Miocene deposits (Weaverville Formation), and in two of...
Sensitivity of endemic Snake River cutthroat trout to acidity and elevated aluminum
D. F. Woodward, Aida M. Farag, M.E. Mueller, E. E. Little, F. A. Vertucci
1989, Transactions of the American Fisheries Society (118) 630-643
Acidic episodes in waters of the western USA, do not last as long and are not as intense as those in the eastern USA, but we found that the native western cutthroat trout Oncorhynchus clarki is sensitive to even brief reductions in pH. In laboratory studies, fish were exposed to acidity (pH...
Velocities of antarctic outlet glaciers determined from sequential Landsat images
Thomas R. MacDonald, Jane G. Ferrigno, Richard S. Williams Jr., Baerbel K. Lucchitta
1989, Antarctic Journal of the United States (24) 105-106
Approximately 91.0 percent of the volume of present-day glacier ice on Earth is in Antarctica; Greenland contains about another 8.3 percent of the volume. Thus, together, these two great ice sheets account for an estimated 99.3 percent of the total. Long-term changes in the volume of glacier ice on our...
Structure of the lower crust beneath the Carolina Trough, U.S. Atlantic continental margin

1989, Journal of Geophysical Research B: Solid Earth (94) 10585-10600
Data from three large-offset seismic profiles provide information on the crustal structure beneath the Carolina trough. The profiles, obtained by the U.S. Geological Survey, the Naval Oceanographic Research Development Agency, and the Scripps Institution of Oceanography in 1985, were oriented parallel to the trough and were located (1) seaward of...
Hydrologic and water-quality characteristics of a Wetland receiving wastewater effluent in St. Joseph, Minnesota
Rob G. Brown, James R. Stark
1989, Wetlands (9) 191-206
Hydrologic and water-quality characteristics were determined for a wetland being used for tertiary treatment of wastewater in St. Joseph, Minnesota. The wetland consists of spruce-tamarack fen and a cattail marsh, with the wastewater being discharged into the fen, and the fen draining into the marsh. The wetland is underlain by...

The abundance of planktonic specimens in foraminiferal assemblages was determined in numerous bottom samples from inner neritic to deep oceanic depths along the Atlantic margin of the northeastern United States. The results augment previous studies in other areas that have...
Water resources of northeast Iowa

1989, Report
In 1965 a cooperative investigation with the U.S. Geological Survey produced Water Atlas No. 1 (Twenter and Coble, 1965). It presented information on the occurrence, availability, use, quality, and future demand of water in 10 counties in the central part of the state. Subsequent investigations produced Water Atlases No. 4...
