Digital map of the state (political) boundaries of Mexico
John Watermolen
1997, Report
This data set represents the state (political) boundaries of Mexico. The Digitial Chart of the World data set had incomplete state boundaries, which was the reason to create this coverage. It was digitized from a 1992 CIA map at a scale of 1:3 million. The coast line came from the...

Bottom boundary layer in south San Francisco Bay, California
Ralph T. Cheng, Jeffrey W. Gartner, Richard E. Smith
1997, Journal of Coastal Research (Special Issue 25) 49-62
Detailed velocity distributions within the benthic turbulent boundary layer were measured by a Broad Band Acoustic Doppler Current Profiler (BB-ADCP) in South San Francisco Bay, California. In "mode 5", the BB-ADCP was able to measure velocity in 5 cm increments. The validation of these measurements was achieved by comparing the...
Hydrogeology of the Tully Valley and characterization of mudboil activity, Onondaga County, New York
William M. Kappel, Donald A. Sherwood, William H. Johnston
1996, Water-Resources Investigations Report 96-4043
Mudboil activity in the Tully Valley, in central New York, is causing turbidity in nearby Onondaga Creek, where it has caused a bridge to collapse; it also has threatened or damaged other structures and has caused extensive land subsidence. Mudboil activity was intermittent from its first reported appearance in the...
Assessment of saltwater intrusion in southern coastal Broward County, Florida
M. L. Merritt
1996, Water-Resources Investigations Report 96-4221
Of the counties in southeastern Florida, Broward County has experienced some of the most severe effects of saltwater intrusion into the surficial Biscayne aquifer because, before 1950, most public water-supply well fields in the county were constructed near the principal early population centers located less than 5 miles from the...

Two life stages of three federally-listed endangered fishes, Colorado squawfish (Ptychocheilus lucius), bonytail (Gila elegans), and razorback sucker (Xyrauchen texanus) were exposed to copper, selenate, selenite, and zinc individually, and to mixtures of nine inorganics in a reconstituted water that simulated the water quality...
Toxicity of fire retardant chemicals to aquatic organisms: Progress report
Steven J. Hamilton, Susan F. McDonald, Mark P. Gaikowski, Kevin J. Buhl
1996, Conference Paper, Proceedings: International Wildland Fire Foam Symposium and Workshop
Fire retardants and suppressants used extensively in North America are often applied in environmentally sensitive areas that may contain endangered, threatened, or economically important plant and animal species. We conducted laboratory acute toxicity tests in both hard and soft waters with five commonly used fire control chemicals (Fire Trol LCG-R,...

Ground-water development in Utah and effects on ground-water levels and chemical quality
Joseph S. Gates, David V. Allen
1996, Cooperative Investigations Report 37
Systematic ground-water development began in Utah shortly after settlement by Mormon pioneers in 1847. By 1939, about 230,000 acrefeet per year of ground water was being withdrawn from wells for irrigation, public supply, industrial use, and rural-domestic and stock supply. Withdrawals increased from about 600,000 to 700,000 acre-feet per year...
Use of the semipermeable membrane device (SPMD) to sample polycyclic aromatic hydrocarbon pollution in a lotic system

1996, Polycyclic Aromatic Compounds (8) 53-65
Relative concentrations of aqueous polycyclic aromatic hydrocarbons (PAH) were investigated in an urban creek. Samples were obtained at five sites within a 600-m segment of the creek that is critical habitat for an endangered species of fish. the sampling technique entailed immersion of semipermeable membrane devices (SPMDs) in the water...

Choosing optimum station configurations for summarizing water quality characteristics, in 1994 Annual Report, San Francisco Estuary Regional Monitoring Program for Trace Substances: San Francisco Estuary Institute
James E. Cloern, Brian E. Cole, J.M. Caffrey, A.D. Jassby
1996, Report, 1994 Annual Report: San Francisco Estuary Regional Monitoring Program for Trace Substances
One of the central problems in regional monitoring is choosing a station array that accurately reflects the distribution of values for the entire region of interest. For time-consuming or expensive measurements, an additional goal is to make the number of sampling locations and times as small as possible. These problems...
Suspended-solids flux at a shallow-water site in south San Francisco Bay, California
Jessica R. Lacy, David H. Schoellhamer, Jon R. Burau
1996, Conference Paper
Time series measurements of current velocity and suspended solids-concentration (SSC) made during December 1993 and March 1994 at a shallow-water site in South San Francisco Bay were used to estimate and compare suspended-solids flux during the two periods. In December, the average residual flux at the site was 2.88 g/m/s,...
The developing framework of marine ecotoxicology: Pollutants as a variable in marine ecosystems?
Samuel N. Luoma
1996, Journal of Experimental Marine Biology and Ecology (200) 29-55
Marine ecosystems include a subset in which at least some interrelated geochemical, biochemical, physiological, population and community characteristics are changed by pollutants. Moderate contamination is relatively widespread in coastal and estuarine ecosystems, so the subset of ecosystems with at least some processes affected could be relatively large. Pollutant influences have...
Mapping the neutralizing epitopes on the glycoprotein of infectious haematopoietic necrosis virus, a fish rhabdovirus
C. Huang, M.S. Chien, M.L. Landolt, W. Batts, J. Winton
1996, Journal of General Virology (77) 3033-3040
Twelve neutralizing monoclonal antibodies (MAbs) against the fish rhabdovirus, infectious haematopoietic necrosis virus (IHNV), were used to select 20 MAb escape mutants. The nucleotide sequence of the entire glycoprotein (G) gene was determined for six mutants representing differing cross-neutralization patterns and each had a single nucleotide change leading to a...
Effects of selenium dietary enhancement on hatchery-reared coho salmon, Oncorhynchus kisutch (Walbaum), when compared with wild coho: hepatic enzymes and seawater adaptation evaluated.
S.P. Felton, M.L. Landolt, R. Grace, A.N. Palmisano
1996, Aquaculture Research (27) 135-142
Hatchery-reared coho salmon, Oncorhynchus kisutch (Walbaum), were fed elevated levels of selenium (as Na2SeO3) to raise eviscerated body burdens to the level measured in wild counterparts. The goal was to find a dietary concentration that would achieve the desired effect without causing damage to growth and normal development. To measure...
