Hydrogeology of the Canal Creek area, Aberdeen Proving Ground, Maryland
J.P. Oliveros, D.A. Vroblesky
1989, Water-Resources Investigations Report 89-4021
Geologic and borehole geophysical logs made at 77 sites show that the hydrogeologic framework of the study area consists of a sequence of unconsolidated sediments typical of the Coastal Plain of Maryland. Three aquifers and two confining units were delineated within the study area. From the surface down, they are:...
Water resources data, Tennessee, water year 1988

1989, Water Data Report TN-88-1
Water resources data for the 1988 water year for Tennessee consist of records of stage, discharge, and water quality of streams and springs; stage, contents, and water quality of lakes and reservoirs; water levels and water quality of wells; and quantity and quality of precipitation. This report contains discharge records...

US Geological Survey Toxic Substances Hydrology Program: Proceedings of the technical meeting, Phoenix, Arizona, September 26-30, 1988
Gail E. Mallard, Stephen E. Ragone, editor(s)
1989, Water-Resources Investigations Report 88-4220
Crude oil floating at the surface of a shallow aquifer of glacial outwash, near Bemidji, Minnesota, is altered by geochemical processes. Hydrocarbons from the oil are attenuated by several reactions that include aerobic and anaerobic microbial degradation. These degradation reactions result in the development of geochemical facies in the shallow...
National assessment of undiscovered conventional oil and gas resources, USGS-MMS working paper
Water Resources Division, U.S. Geological Survey, Minerals Management Service
1989, Open-File Report 88-373
In 1981, the U.S. Geological Survey (USGS) published the results of a 1980 national assessment of undiscovered oil and natural gas resources for the United States, including the Outer Continental Shelf (OCS). The publication, USGS Circular 860, was entitled "Estimates of Undiscovered Recoverable Conventional Resources of Oil and Gas in...
Water resources data for Indiana, water year 1988
Dale R. Glatfelter, Ronald E. Thompson Jr., Graham E. Nell
1989, Water Data Report IN-88-1
Water resources data for the 1988 water year for Indiana consist of records of discharge, stage, and water quality of streams and wells; reservoir stage and contents; and water levels in lakes and wells. This report contains records of discharge for 176 stream-gaging stations, stage for 4 stream stations, stage and contents for...
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...
Streamside habitats in southern forested wetlands: Their role and implications for management
Rebecca J. Howard, James A. Allen
1989, General Technical Report SE-50
The value of streamside forests to fish and wildlife and the influence of forest management on their value have been recognized in a general sense for decades. However, in today’s climate of increasing environmental regulation and intensive forest management, there is need for more detailed understanding of the value of streamside forests to fish and wildlife....
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...
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...
