Generalized lithology and lithogeochemical character of near-surface bedrock in the New England region
G.R. Robinson Jr., K. E. Kapo
2003, Open-File Report 2003-225
This geographic information system (GIS) data layer shows the dominant lithology and geochemical, termed lithogeochemical, character of near-surface bedrock in the New England region covering the states of Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. The bedrock units in the map are generalized into groups based on their...
Water vapour correction of the daily 1 km AVHRR global land dataset: Part I validation and use of the Water Vapour input field
Thomas P. DeFelice, D. Lloyd, D. J. Meyer, T. T. Baltzer, P. Piraina
2003, International Journal of Remote Sensing (24) 2365-2375
An atmospheric correction algorithm developed for the 1 km Advanced Very High Resolution Radiometer (AVHRR) global land dataset was modified to include a near real-time total column water vapour data input field to account for the natural variability of atmospheric water vapour. The real-time data input field used for this...
Geotechnical Analysis of Paleoseismic Shaking Using Liquefaction Features: Part I. Major Updating of Analysis Techniques
Scott M. Olson, Russell A. Green, Stephen F. Obermeier
2003, Open-File Report 2003-307
A new methodology is proposed for the geotechnical analysis of strength of paleoseismic shaking using liquefaction effects. The proposed method provides recommendations for selection of both individual and regionally located test sites, techniques for validation of field data for use in back-analysis, and use of a recently developed energy-based solution to back-calculate paleoearthquake magnitude...
FORSPAN Model Users Guide
T. R. Klett, Ronald R. Charpentier
2003, Open-File Report 2003-354
The USGS FORSPAN model is designed for the assessment of continuous accumulations of crude oil, natural gas, and natural gas liquids (collectively called petroleum). Continuous (also called ?unconventional?) accumulations have large spatial dimensions and lack well defined down-dip petroleum/water contacts. Oil and natural gas therefore are not localized by buoyancy in water in these...
The U.S. Geological Survey streamflow and observation-well network in Massachusetts and Rhode Island
Phillip J. Zarriello, Roy S. Socolow
2003, Open-File Report 2003-277
The U.S. Geological Survey began systematic streamflow monitoring in Massachusetts nearly 100 years ago (1904) on the Connecticut River at Montague City. Since that time, hydrologic data collection has evolved into a monitoring network of 103 streamgage stations and 200 ground-water observation wells in Massachusetts and Rhode Island (2000 water...
Rim Sim: A Role-Play Simulation
Robert C. Barrett, Suzanne L. Frew, David G. Howell, Herman A. Karl, Emily B. Rudin
2003, Bulletin 2212
Rim Sim is a 6-hour, eight-party negotiation that focuses on creating a framework for the long-term disaster-recovery efforts. It involves a range of players from five countries affected by two natural disasters: a typhoon about a year ago and an earthquake about 6 months ago. The players are members of...
Station corrections for the Katmai Region Seismic Network
Cheryl K. Searcy
2003, Open-File Report 2003-403
Most procedures for routinely locating earthquake hypocenters within a local network are constrained to using laterally homogeneous velocity models to represent the Earth's crustal velocity structure. As a result, earthquake location errors may arise due to actual lateral variations in the Earth's velocity structure. Station corrections can be used to...
Ground-water use, locations of production wells, and areas irrigated using ground water in 1998, middle Humboldt River basin, north-central Nevada
Russell W. Plume
2003, Water-Resources Investigations Report 2003-4227
In 1998, ground water was being pumped from about 420 production wells in the middle Humboldt River Basin for a variety of uses. Principal uses were for agriculture, industry, mining, municipal, and power plant purposes. This report presents a compilation of the number and types of production wells, areas irrigated...
Resource allocation in offspring provisioning: An evaluation of the conditions favoring the evolution of matrotrophy
Joel C. Trexler, Donald L. DeAngelis
2003, American Naturalist (162) 574-585
We used analytic and simulation models to determine the ecological conditions favoring evolution of a matrotrophic fish from a lecithotrophic ancestor given a complex set of trade‐offs. Matrotrophy is the nourishment of viviparous embryos by resources provided between fertilization and parturition, while lecithotrophy describes embryo nourishment provided before fertilization. In...
Elastic properties of overpressured and unconsolidated sediments
Myung W. Lee
2003, Bulletin 2214
Differential pressure affects elastic velocities and Poisson?s ratio of sediments in such a way that velocities increase as differential pressure increases. Overpressured zones in sediments can be detected by observing an increase in Poisson?s ratio with a corresponding drop in elastic velocities. In highly overpressured sands, such as shallow water...
U.S. Geological Survey Subsidence Interest Group Conference: Proceedings of the technical meeting, Galveston, Texas, November 27-29, 2001
Keith R. Prince, Devin L. Galloway, editor(s)
2003, Open-File Report 2003-308
InSAR is a powerful technique that uses radar data acquired at different times to measure land-surface deformation, or displacement, over large areas at a high level of spatial detail and a high degree of measurement resolution. InSAR displacement maps (interferograms), in conjunction with other hydrogeologic data, have been used to...
Low-flow characteristics and profiles for the Rocky River in the Yadkin-Pee Dee River basin, North Carolina, through 2002
J. Curtis Weaver, Jason M. Fine
2003, Water-Resources Investigations Report 2003-4147
An understanding of the magnitude and frequency of low-flow discharges is an important part of protecting surface-water resources and planning for municipal and industrial economic expansion. Low-flow characteristics are summarized for 12 continuous-record gaging stations and 44 partial-record measuring sites in the Rocky River basin in North Carolina. Records of...
Suspended sediment and bed load in three tributaries to Lake Emory in the upper Little Tennessee River basin, North Carolina, 2000-02
Carolyn J. Oblinger
2003, Water-Resources Investigations Report 2003-4194
A study was conducted in the upper Little Tennessee River basin to characterize suspended-sediment and bed-load sediment transport into Lake Emory from the main stem and two major tributaries--Cartoogechaye Creek and the Cullasaja River. Suspended-sediment concentrations in the discharge from Lake Emory also were measured. Weekly samples for suspended-sediment concentration...
Overview of mine drainage geochemistry at historical mines, Humboldt River basin and adjacent mining areas, Nevada
J. Thomas Nash, Lisa L. Stillings
2003, Bulletin 2210-E
Reconnaissance hydrogeochemical studies of the Humboldt River basin and adjacent areas of northern Nevada have identified local sources of acidic waters generated by historical mine workings and mine waste. The mine-related acidic waters are rare and generally flow less than a kilometer before being neutralized by natural processes. Where waters...
Simulation of hydrodynamics, temperature, and dissolved oxygen in Table Rock Lake, Missouri, 1996–1997
W. Reed Green, Joel M. Galloway, Joseph M. Richards, Edwin A. Wesolowski
2003, Water-Resources Investigations Report 2003-4237
Outflow from Table Rock Lake and other White River reservoirs support a cold-water trout fishery of substantial economic yield in south-central Missouri and north-central Arkansas. The Missouri Department of Conservation has requested an increase in existing minimum flows through the Table Rock Lake Dam from the U.S. Army Corps of...
Leaching, transport, and methylation of mercury in and around abandoned mercury mines in the Humboldt River basin and surrounding areas, Nevada
John E. Gray, Lisa L. Stillings
2003, Bulletin 2210-C
Mercury and methylmercury concentrations were measured in mine wastes, stream sediments, and stream waters collected both proximal and distal from abandoned mercury mines to evaluate mercury contamination and mercury methylation in the Humboldt River system. The climate in the study area is arid, and due to the lack of mine-water...
