Fecal-indicator bacteria in surface waters of the Santee River Basin and coastal drainages, North and South Carolina, 1995-98
Lance J. Wilhelm, Terry L. Maluk
1998, Fact Sheet 085-98
IntroductionHigh levels of fecal-indicator bacteria in rivers and streams can indicate the possible presence of pathogenic (disease-causing) microorganisms. Cholera, typhoid fever, bacterial dysentery, infectious hepatitis, and cryptosporidiosis are some of the well known waterborne diseases that spread through water contaminated and fecal matter. Eye, ear, nose, and throat infections also...
Declassified intelligence satellite photographs
Water Resources Division, U.S. Geological Survey
1998, Fact Sheet 090-96
Recently declassified photographs from spy satellites are an important addition to the record of the Earth?s land surface held by the U.S. Geological Survey (USGS). More than 800,000 high-resolution photos taken between 1959 through 1972 were made available by Executive Order of the President. The collection is held at the...
Explore the virtual side of earth science
Water Resources Division, U.S. Geological Survey
1998, Fact Sheet 106-98
Scientists have always struggled to find an appropriate technology that could represent three-dimensional (3-D) data, facilitate dynamic analysis, and encourage on-the-fly interactivity. In the recent past, scientific visualization has increased the scientist's ability to visualize information, but it has not provided the interactive environment necessary for rapidly changing the model...
Water quality of selected effluent-dependent stream reaches in southern Arizona as indicated by concentrations of periphytic chlorophyll a and aquatic-invertebrate communities
Joseph B. Gebler
1998, Water-Resources Investigations Report 98-4199
Concentrations of chlorophyll a and indices computed for aquatic- invertebrate communities in two effluent-dependent stream reaches on the Santa Cruz River and one on the Salt River were compared to those in noneffluent-dependent streams to examine potential differences in water quality. Periphytic chlorophyll a from riffle habitats and aquatic-invertebrate communities...

Water Resources Division, U.S. Geological Survey
1998, Mineral Commodity Summaries 1998
Published on an annual basis, this report is the earliest Government publication to furnish estimates covering nonfuel mineral industry data. Data sheets contain information on the domestic industry structure, Government programs, tariffs, and 5-year salient statistics for over 90 individual minerals and materials....
Fungal life-styles and ecosystem dynamics: Biological aspects of plant pathogens, plant endophytes and saprophytes
R. J. Rodriguez, R. S. Redman
1997, Advances in Botanical Research (24) 169-193
This chapter discusses various biochemical, genetic, ecological, and evolutionary aspects of fungi that express either symbiotic or saprophytic life-styles. An enormous pool of potential pathogens exists in both agricultural and natural ecosystems, and virtually all plant species are susceptible to one or more fungal pathogens. Fungal pathogens have the potential...
