Salt tolerance of southern baldcypress Salt tolerance of southern baldcypress

Historically, cypress-tupelo swamps covered much of the low-lying coastal regions of the Southeast. However, saltwater intrusion and increased flooding over the past 30 years, combined with past logging, have depleted the numbers and decreased the survival and growth of baldcypress (Taxodium distichum) in coastal areas along the Gulf of Mexico.

Carrier effects of dosing the h4iie cells with 3,3′,4,4tt´etrachlorobiphenyl (PCB77) in dimethyl sulfoxide or isooctane Carrier effects of dosing the h4iie cells with 3,3′,4,4tt´etrachlorobiphenyl (PCB77) in dimethyl sulfoxide or isooctane

A rat hepatoma cell line, H4IIE serves as a bioassay tool to assess the potential toxicity of dioxin-like chemicals, including polychlorinated biphenyls (PCB) in environmental samples. PCB exposure to these cells induces cytochrome (CYP) P4501A1 activity in a dose-dependent fashion, thus allowing assessment of mixtures. The objective of this study was to determine the effect of different...

Comparison of the 2-, 25-, and 100-year recurrence interval floods computed from observed data with the 1995 urban flood-frequency estimating equations for Georgia Comparison of the 2-, 25-, and 100-year recurrence interval floods computed from observed data with the 1995 urban flood-frequency estimating equations for Georgia

Flood-frequency relations were computed for 28 urban stations, for 2-, 25-, and 100-year recurrence interval floods and the computations were compared to corresponding recurrence interval floods computed from the estimating equations from a 1995 investigation. Two stations were excluded from further comparisons or analyses because neither station had a significant flood during the period...

Water-quality assessment of the Las Vegas Valley area and the Carson and Truckee River basins, Nevada and California: Nutrients, pesticides, and suspended sediment, October 1969-April 1990 Water-quality assessment of the Las Vegas Valley area and the Carson and Truckee River basins, Nevada and California: Nutrients, pesticides, and suspended sediment, October 1969-April 1990

The U.S. Geological Survey National Water-Quality Assessment Program (NAWQA) is designed to provide long-term, consistent information on water quality that can be used to describe local, regional, and national conditions. The full-scale NAWQA Program, initiated in 1991, includes both study-unit and national synthesis activities. Study-unit investigations provide scientific data and...

Radon in ground water in Guilford County, North Carolina Radon in ground water in Guilford County, North Carolina

Approximately 30 percent of the water used in Guilford County, North Carolina, is from ground-water sources. All rural supplies are from ground water; approximately 65,000 residents used ground water for their domestic water supplies in 1990. The U.S. Geological Survey (USGS), in cooperation with the Guilford County Soil and Water Conservation District and the Guilford County Department...

Discharge measurement in tidally affected channels during a hydrographic estuarine survey of Sabine Lake, Texas Discharge measurement in tidally affected channels during a hydrographic estuarine survey of Sabine Lake, Texas

A hydrographic survey of Sabine Lake, a broad, shallow estuary lying on the Texas-Louisiana border, was conducted in June 1996 to help address questions relating to potential environmental effects of future water demands in Texas. The use of a variety of new instruments in this study is one means by which automation is improving efficiency and effectiveness of these efforts by increasing...
