Assessment of severity and distribution of corrosive ground water in Pennsylvania Assessment of severity and distribution of corrosive ground water in Pennsylvania
Relations between corrosive ground water, water chemistry, and geology in Pennsylvania were evaluated by use of a modified version of the Langelier Saturation Index (LSIsn) and a geologic contact dataset in a Geographic Information System. Water-chemistry information for water samples collected from 4,839 combined private and public-supply wells from 1900 to 1993 was used to calculate...

HYSEP: A Computer Program for Streamflow Hydrograph Separation and Analysis HYSEP: A Computer Program for Streamflow Hydrograph Separation and Analysis
HYSEP is a computer program that can be used to separate a streamflow hydrograph into base-flow and surface-runoff components. The base-flow component has traditionally been associated with ground-water discharge and the surface-runoff component with precipitation that enters the stream as overland runoff. HYSEP includes three methods of hydrograph separation that are referred to in the...

An 84-kyr paleomagnetic record from the sediments of Lake Baikal, Siberia An 84-kyr paleomagnetic record from the sediments of Lake Baikal, Siberia
We have conducted a paleomagnetic study of sediment cores obtained from the Selenga prodelta region of Lake Baikal, Russia. This record, which spans approximately the last 84 kyr, contributes to a better understanding of the nature of geomagnetic field behavior in Siberia and is a useful correlation and dating tool. We demonstrate that the Lake Baikal sediments are recording variations...

Preliminary analysis of down-core biotic assemblages Bob Allen Keys, Everglades National Park, Florida Bay Preliminary analysis of down-core biotic assemblages Bob Allen Keys, Everglades National Park, Florida Bay
Introduction A series of short piston cores ( 2m) were taken from eleven stations in Florida Bay in May, 1994 by researchers from the U.S. Geological Survey (St. Petersburg, FL., Woods Hole, MA., and Denver CO.) in cooperation with South Florida Water Management District, and the Everglades National Park, and the National Oceanic and Atmospheric Administration (NOAA). Core 6A from Bob...

The influence of Hurricane Andrew on sediment distribution in Louisiana coastal marshes The influence of Hurricane Andrew on sediment distribution in Louisiana coastal marshes
The areal extent and temporal patterns of sediment deposition in delta marshes and shallow water bodies of Louisiana associated with the passage of Hurricane Andrew were determined from sediment traps, marker horizons, and benchmarks deployed for other studies. Data were collected over different time scales from 11 sites representing salt, brackish, and intermediate marshes, shallow...

Population size, trends, and conservation problems of the Double-Crested Cormorant on the Pacific Coast of North America Population size, trends, and conservation problems of the Double-Crested Cormorant on the Pacific Coast of North America
Population size, trends and conservation problems of the Double-crested Cormorant (Phalacrocorax auritus) were collated for the Pacific coast of North America using available data up to 1992. About 54,942 birds currently breed there, including roughly 5,848 (5,622 at 90 coastal colonies and at least 226 at 5 interior colonies) and 49,094 (43,358 at 126 coastal colonies and at least 5,736...

Audit of VSMOW distributed by the United States National Institute of Standards and Technology Audit of VSMOW distributed by the United States National Institute of Standards and Technology
Bright-orange floating matter (possibly algae) has been observed in the United States supply of some ampoules and in one of two 10-L primary glass storage flasks of the isotopic reference water VSMOW (Vienna Standard Mean Ocean Water). Within experimental error, ampoules with and without this orange matter are identical in stable hydrogen and oxygen isotopic composition. Thus, the North...
