Exposure of delta smelt to dissolved pesticides in 2000
Kathryn Kuivila, G. Edward Moon
2002, Interagency Ecological Program Newsletter (15) 42-45
Delta smelt abundance in San Francisco Estuary has been declining since 1983. The exposure of delta smelt to toxic pesticides during larval and juvenile life stages may be one possible factor of this decline (Bennett and Moyle 1996; Moyle and others 1996). Although pesticides have been detected in the Delta...

Thomas E. Moore, Christopher J. Potter, Paul B. O'Sullivan
2002, AAPG Bulletin (86) 1153-1153
Five structural levels underlie the Brooks Range foothills, from lowest to highest: (1) autochthon, at a depth of ~9 km; (2) Endicott Mountains allochthon (EMA), thickest under the northern Brooks Range (>15 km) and wedging out northward above the autochthon; (3) higher allochthons (HA), with a composite thickness of 1.5+...

Bayesian time series analysis of segments of the Rocky Mountain trumpeter swan population
Christopher K. Wright, Richard S. Sojda, Daniel Goodman
2002, Waterbirds (25) 319-326
A Bayesian time series analysis technique, the dynamic linear model, was used to analyze counts of Trumpeter Swans (Cygnus buccinator) summering in Idaho, Montana, and Wyoming from 1931 to 2000. For the Yellowstone National Park segment of white birds (sub-adults and adults combined) the estimated probability of a positive growth...
Real-time kinematic surveying at the Osage-Skiatook Petroleum Environmental Research sites, Osage County, Oklahoma
Marvin M. Abbott
2002, Conference Paper, 9th International Petroleum Environmental Conference
Highly accurate survey-grade Global Positioning System (GPS) technology was used at the two Osage-Skiatook petroleum environmental research sites to document the locations of observation wells, geoprobe holes, and other sampling sites of 15 research scientists. Real-time kinematic (RTK) GPS was the method used, because it is stable, fast, and accurate.Initially...

2002, Conference Paper, 9th International Petroleum Environmental Conference
We are involved in a multidisciplinary investigation to study the transport, fate, and natural attenuation of inorganic salts, trace metals, radionuclides and organic compounds present in produced water, and their impacts on soil, surface and ground water and the local ecosystem at the Osage-Skiatook Petroleum Environmental Research (OSPER) A and...
Fuzzy logic merger of spectral and ecological information for improved montane forest mapping.
Joseph D. White, Steven W. Running, Kevin C. Ryan, Carl H. Key
2002, Geocarto International (17) 61-68
Environmental data are often utilized to guide interpretation of spectral information based on context, however, these are also important in deriving vegetation maps themselves, especially where ecological information can be mapped spatially. A vegetation classification procedure is presented which combines a classification of spectral data from Landsat‐5 Thematic Mapper (TM)...
Hydrologic controls on the subsurface transport of oil-field brine at the Osage-Skiatook Petroleum Environmental Research (OSPER) B Site, Oklahoma

2002, Conference Paper, 9th International Petroleum Environmental Conference
An active oil production site (Osage-Skiatook petroleum environmental research Site B) in Osage County, Oklahoma is under study to determine the impacts on soils and rock of brine and hydrocarbon spills. The goals of the soil and rock characterization are to 1) document and identify the type, degree, and areal...

2002, Conference Paper, 9th International Petroleum Environmental Conference
Ground electromagnetic and dc resistivity geophysical surveys were used to interpret the subsurface distribution of salinized soil, water, and bedrock at two sites (A and B) and to characterize the larger scale hydrologic setting. Measurements were made on grids of about 1000 square meters using a very shallow penetrating (less...
Transforming the Rockies: Human forces, settlement patterns, and ecosystem effects
William R. Travis, David M. Theobald, Daniel B. Fagre
Jill Baron, editor(s)
2002, Book chapter, Rocky Mountain futures: An ecological perspective
The current ecological condition of the Rocky Mountains can be viewed from two somewhat opposing perspectives. The first is that human occupation has had relatively little effect on the Rockies: large natural, if not pristine, areas remain, and the region's open spaces provide wildlife habitat, majestic scenery, and a sense...
Regional structural framework and petroleum assessment of the Brooks Range foothills and southern coastal plain, National Petroleum Reserve, Alaska
