Selected water-level records for western Oklahoma, 1950-1975
Robert L. Goemaat
1977, Open-File Report 77-73
A systematic program to collect water-level records in Oklahoma began in 1937. The objectives of this program are (1) to provide long-term records of water-level fluctuations in representative wells, (2) to facilitate the prediction of water-level trends and indicate future availability of ground-water supplies, and (3) to provide information for...

D.W. Fisk, J.C. Rosenau
1977, Water-Resources Investigations Report 77-1
A map showing the potentiometric surface of the Floridan aquifer was prepared for that area north and west of Gainesville to near Tallahassee, Florida. Contoured at 10-foot (3.048-meter) intervals and at a scale of 1:500,000, the map illustrates the altitude to which water would rise in tightly cased wells that...

P. P. Ross
1977, Water-Resources Investigations Report 77-113
Arizona is divided into 67 ground-water areas, and individual areas are selected for intensive data collection once every 6 years. The data collected in the lower Verde River area are given on a map that shows altitude of the water level, depth of water, well depth, chemical quality of the...
A synoptic survey of trace metals in bottom sediments of the Willamette River, Oregon
David A. Rickert, V. C. Kennedy, S. W. McKenzie, W. G. Hines
1977, Circular 715-F
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...

Urban and regional land use change detected by using Landsat data
William J. Todd
1977, Journal of Research of the U.S. Geological Survey (5) 529-534
The Atlanta Regional Commission and the Earth Resources Observation Systems Data Center participated in a demonstration of the use of Landsat digital data to detect land use change in the Atlanta, Ga., area. Temporal overlays combining Landsat band-5 data from October 1972 and 1974 were made by using the General...
Analysis of street sweepings, Portland, Oregon
Timothy L. Miller, Joseph F. Rinella, Stuart W. McKenzie, Jerry Parmenter
1977, Report
A brief study involving collection and analysis of street sweepings was undertaken to provide the U.S. Army Corps of Engineers with data on physical, chemical, and biological characteristics of dust and dirt accumulating on Portland streets. Most of the analyses selected were based on the pollutant loads predicted by the...
Epithermal beryllium deposits in water-laid tuff, western Utah
David A. Lindsey
1977, Economic Geology (72) 219-232
Epithermal beryllium deposits in western Utah have distinctive geological and geochemical associations that provide guides to exploration for new resources of beryllium and associated metals. Beryllium deposits at Spor Mountain and the Honeycomb Hills are uniquely associated with topaz-bearing rhyolite of Late Tertiary age and are restricted to porous water-laid...
Leech parasitism of waterfowl in North America
David L. Trauger, James C. Bartonek
1977, Wildfowl (28) 143-152
Leech parasitism of waterfowl is widespread in North America. Twenty species of ducks, geese, and swans have been infested by leeches, particularly Theromyzon rude and Placobdella ornata. Sites of attachment include the eyes, nasal passages, and body. Information is lacking on the biology and ecology of duck leeches. Their significance...

Submarine seepage of natural gas in Norton Sound, Alaska
J.D. Cline, M.L. Holmes
1977, Science (198) 1149-1153
Unusual concentrations of dissolved two- to four-carbon alkanes were observed in the waters in Norton Sound in a localized area approximately 40 kilometers south of Nome, Alaska, in 1976. The hydrocarbons were identified in the near-bottom waters downcurrent for more than 100 kilometers from a sea-floor point source. Preliminary dynamic...
Lead and PCB's in canvasback ducks: Relationship between enzyme levels and residues in blood
Michael P. Dieter, Matthew Perry, Bernard M. Mulhern
1977, Archives of Environmental Contamination and Toxicology (5) 1-13
Blood samples were taken for two successive years from canvasback ducks trapped in the Chesapeake Bay. The first winter (1972–1973) five plasma enzymes known to respond to organochlorine poisoning were examined. Abnormal enzyme elevations suggested that 20% of the population sampled (23/115 ducks) might contain organochlorine contaminants, but no residue...
Immunization of sockeye salmon (Oncorhynchus nerka) against vibriosis using the hyperosmotic infiltration technique
Thomas R. Croy, Donald F. Amend
1977, Aquaculture (12) 317-325
Various procedures of hyperosmotic infiltration (HI) and intraperitoneal injection were used to vaccinate sockeye salmon (Oncorhynchus nerka) with killed Vibrio anguillarum. Excellent protection was evident against experimentally induced vibriosis in the groups immunized by HI with 10 × Hanks' balanced salt solution (HBSS), 1 × HBSS with 8.0% NaCl and 5.3%...
Lower Tertiary biostratigraphy of the northern Santa Lucia Range, California
Richard Z. Poore, William V. Sliter, M. H. Link
1977, Journal of Research of the U.S. Geological Survey (5) 735-745
Lower Tertiary strata in .the northern Santa Lucia Range of California are correlated by means of planktonic and benthonic foraminifers. Benthonic foraminiferal assemblages from eight stratigraphic sections range in age from Ynezian to possible basal Refugian. The Paleocene mudstone contains a Ynezian benthonic foraminiferal assemblage. The Ulatisian benthonic assemblage of...

H. C. Mattraw Jr., C. B. Sherwood
1977, Journal of Research of the U.S. Geological Survey (5) 823-834
Rainfall, runoff, and water-quality information were collected in a 19.2-hectare single-family residential area in Broward County, Fla., between April 1974 and September 1975. During this period, 231 rainfall periods were recorded; 106 were large enough to produce runoff, and 30 were sampled for chemical analyses. The fraction of rainfall that...
Solution of water-table and anisotropic flow problems by using the strongly implicit procedure
S. P. Larson, Peter C. Trescott
1977, Journal of Research of the U.S. Geological Survey (5) 815-821
The use of the strongly implicit procedure (SIP) with an additional iteration parameter, β, to scale the residual vector is advantageous to the solution of some ground-waterflow problems. For steady-state water-table problems plagued by excessive elimination of grid blocks during the iteration process, selection of β<1 can be effective in...
Measuring total antimony in geothermal waters by flame atomic absorption spectrometry
R. E. Stauffer
1977, Journal of Research of the U.S. Geological Survey (5) 807-809
A flame atomic absorption procedure utilizing an electrodeless discharge lamp is described for determining total solute antimony in silica-rich geothermal waters. Following NaNO2 oxidation of Sb+3, SbCl5 is extracted from 6 N HCl solution by using MIBK (methyl isobutyl ketone) ; silica in the organic layer is removed by centrifugation....
Solution of three-dimensional groundwater flow equations using the strongly implicit procedure
P.C. Trescott, S. P. Larson
1977, Journal of Hydrology (35) 49-60
A three-dimensional numerical model has been coded to use the strongly implicit procedure for solving the finite-difference approximations to the ground-water flow equation. The model allows for: (1) the representation of each aquifer and each confining bed by several layers; and (2) the use of an anisotropic hydraulic conductivity at...

Hydrologic characteristics of the Madison Limestone, the Minnelusa Formation, and equivalent rocks as determined by well-logging formation evaluation, Wyoming, Montana, South Dakota, and North Dakota
William J. Head, Richard H. Merkel
1977, Journal of Research of the U.S. Geological Survey (5) 473-485
Geophysical logs from wells distributed throughout the Powder River Basin were digitized, processed, and interpreted to get a regional understanding of the lithologic and ground-water characteristics of aquifers in the Madison Limestone and Minnelusa Formation. The percentage of sand, porosity, and apparent ground-water resistivity of the Minnelusa closely follow structural...
Paleohydrologic phenomena recorded by lake sediments
Thomas C. Winter, H.E. Wright Jr.
1977, Earth and Space Science (58) 188-196
Hydrologic phenomena are dynamic, so their understanding and prediction are difficult and challenging. Many are cyclic, ranging from diurnal, seasonal, and annual cycles to climatic fluctuations of many hundreds or thousands of years. Predicting the magnitude and recurrence intervals of long-term fluctuations of these phenomena is a primary...
