Publication Extents

Not all publications have extents, not all extents are completely accurate
Herpetofaunal Inventories of the National Parks of South Florida and the Caribbean: Volume II. Virgin Islands National Park
Kenneth G. Rice, J. Hardin Waddle, Marquette E. Crockett, R.R. Carthy, H. Franklin Percival
2005, Open-File Report 2005-1301
Amphibian declines and extinctions have been documented around the world, often in protected natural areas. Concern for this alarming trend has focused attention on the need to document all species of amphibians that occur within U.S. National Parks and to search for any signs that amphibians may be declining. This...
Inventory of the mosses, liverworts, and lichens of Olympic National Park, Washington- Species list
M. Hutten, Andrea Woodward, K. Hutten
2005, Scientific Investigations Report 2005-5240
The identification of non-vascular cryptogam species (lichens, mosses, liverworts, and hornworts) is especially challenging because of their small size, their often microscopic or chemical distinguishing features, and their enormous diversity. Consequently, they are a poorly known component of Olympic National Park, despite their ecological and aesthetic importance. This project is...
Water quality and ground-water/surface-water interactions along the John River near Anaktuvuk Pass, Alaska, 2002-2003
Edward H. Moran, Timothy P. Brabets
2005, Scientific Investigations Report 2005-5229
The headwaters of the John River are located near the village ofAnaktuvuk Pass in the central Brooks Range of interior Alaska. With the recent construction of a water-supply system and a wastewater-treatment plant, most homes in Anaktuvuk Pass now have modern water and wastewater systems. The effluent from the treatment plant discharges into a...
Herpetofaunal Inventories of the National Parks of South Florida and the Caribbean: Volume III. Big Cypress National Preserve
Kenneth G. Rice, J. Hardin Waddle, Marquette E. Crockett, Brian M. Jeffrey, Amanda N. Rice, H. Franklin Percival
2005, Open-File Report 2005-1300
Amphibian declines and extinctions have been documented around the world, often in protected natural areas. Concern for this trend has prompted the U.S. Geological Survey and the National Park Service to document all species of amphibians that occur within U.S. National Parks and to search for any signs that amphibians...
Water-quality and Llake-stage data for Wisconsin Lakes, Water Year 2004
W. J. Rose, H.S. Garn, G. L. Goddard, S.B. Marsh, D.L. Olson, Dale M. Robertson
2005, Open-File Report 2005-1147
The U.S. Geological Survey (USGS), in cooperation with local and other agencies, collects data at selected lakes throughout Wisconsin. These data, accumulated over many years, provide a data base for developing an improved understanding of the water quality of lakes. To make these data available to interested parties outside the...
Earth Observing-1 Extended Mission
Water Resources Division, U.S. Geological Survey
2005, Fact Sheet 2005-3060
Since November 2000, the National Aeronautics and Space Administration (NASA) Earth Observing-1 (EO-1) mission has demonstrated the capabilities of a dozen spacecraft sensor and communication innovations. Onboard the EO-1 spacecraft are two land remote sensing instruments. The Advanced Land Imager (ALI) acquires data in spectral bands and at resolutions similar...
Water-quality data from ground- and surface-water sites near concentrated animal feeding operations (CAFOs) and non-CAFOs in the Shenandoah Valley and eastern shore of Virginia, January-February, 2004
Karen C. Rice, Michele M. Monti, Matthew R. Ettinger
2005, Open-File Report 2005-1388
Concentrated animal feeding operations (CAFOs) result from the consolidation of small farms with animals into larger operations, leading to a higher density of animals per unit of land on CAFOs than on small farms. The density of animals and subsequent concentration of animal wastes potentially can cause contamination of nearby ground...
Documentation of the Streamflow-Routing (SFR2) Package to Include Unsaturated Flow Beneath Streams - A Modification to SFR1
Richard G. Niswonger, David E. Prudic
2005, Techniques and Methods 6-A13
Many streams in the United States, especially those in semiarid regions, have reaches that are hydraulically disconnected from underlying aquifers. Ground-water withdrawals have decreased water levels in valley aquifers beneath streams, increasing the occurrence of disconnected streams and aquifers. The U.S. Geological Survey modular ground-water model (MODFLOW-2000) can be used...
Archive of digital Boomer seismic reflection data collected during USGS Cruise 94CCT02, south-central South Carolina coastal region, August 1994
Karynna Calderon, Shawn V. Dadisman, Jack L. Kindinger, James G. Flocks, Dana S. Wiese
2005, Data Series 147
In August of 1994, the U.S. Geological Survey, in cooperation with Coastal Carolina University, conducted marine geophysical surveys in numerous water bodies adjacent to the south-central South Carolina coastal region. Data were collected aboard the MS Coastal in the Ashley, North Edisto, Wadmalaw, Dawho, South Edisto, and Ashepoo Rivers; the...
Using hydrogeomorphic criteria to classify wetlands on Mt. Desert Island, Maine – Approach, classification system, and examples
Martha G. Nielsen, Glenn R. Guntenspergen, Hilary A. Neckles
2005, Scientific Investigations Report 2005-5244
A wetland classification system was designed for Mt. Desert Island, Maine, to help categorize the large number of wetlands (over 1,200 mapped units) as an aid to understanding their hydrologic functions. The classification system, developed by the U.S. Geological Survey (USGS), in cooperation with the National Park Service, uses a...
Sediment-transport investigations of the upper Yellowstone River, Montana, 1999 through 2001: Data collection, analysis, and simulation of sediment transport
Stephen R. Holnbeck
2005, Scientific Investigations Report 2005-5234
The upper Yellowstone River in Montana is an important State and national water resource, providing recreational, agricultural, and commercial benefits. Floods in 1996 and 1997, with recorded peak discharges having recurrence intervals close to 100 years, caused substantial streambank erosion and hill- slope mass wasting. Large quantities of sand-,...
Early to middle Jurassic salt in Baltimore Canyon trough
B. Ann McKinney, Myung W. Lee, Warren F. Agena, C. Wylie Poag
2005, Open-File Report 2004-1435
A pervasive, moderately deep (5-6 s two-way traveltime), high-amplitude reflection is traced on multichannel seismic sections over an approximately 7500 km² area of Baltimore Canyon Trough. The layer associated with the reflection is about 25 km wide, about 60 m thick in the center, and thins monotonically laterally, though asymmetrically,...
Naturally Occurring Arsenic in Ground Water, Norman, Oklahoma, 2004, and Remediation Options for Produced Water
S. Jerrod Smith, Scott Christenson
2005, Fact Sheet 2005-3111
In 2000, the U.S. Environmental Protection Agency (EPA) reviewed the arsenic drinking water standard for public water supplies. Considering the available research and statistics on the health effects of arsenic ingestion, the EPA reduced the Maximum Contaminant Level (MCL) for public drinking water from 50 micrograms per liter (?g/L) to...
Topography and Landforms of Ecuador
Peter G. Chirico, Michael B. Warner
2005, Data Series 136
EXPLANATION The digital elevation model of Ecuador represented in this data set was produced from over 40 individual tiles of elevation data from the Shuttle Radar Topography Mission (SRTM). Each tile was downloaded, converted from its native Height file format (.hgt), and imported into a geographic information system (GIS) for additional...
Occupancy models to study wildlife
Larissa Bailey, Michael John Adams
2005, Fact Sheet 2005-3096
Many wildlife studies seek to understand changes or differences in the proportion of sites occupied by a species of interest. These studies are hampered by imperfect detection of these species, which can result in some sites appearing to be unoccupied that are actually occupied. Occupancy models solve this problem and...
