The majority of the tests were detonated underground, introducing contaminants into the ground-water system (Laczniak and others, 1996). An understanding of the ground-water flow paths is necessary to evaluate the extent of ground-water contamination. This report provides information specific to Yucca Flat on the Nevada Test Site.
\nCritical to understanding the ground-water flow beneath Yucca Flat is an understanding of the subsurface geology, particularly the structure and distribution of the pre-Tertiary rocks, which comprise both the major regional aquifer and aquitard sequences (Winograd and Thordarson, 1975; Laczniak and others, 1996). Because the pre-Tertiary rocks are not exposed at the surface of Yucca Flat their distribution must be determined through well logs and less direct geophysical methods such as potential field studies.
\nIn previous studies (Phelps and others, 1999; Phelps and Mckee, 1999) developed a model of the basement surface of the Paleozoic rocks beneath Yucca Flat and a series of normal faults that create topographic relief on the basement surface.
\nIn this study the basement rocks and structure of Yucca Flat are examined in more detail using the basement gravity anomaly derived from the isostatic gravity inversion model of Phelps and others (1999) and high-resolution magnetic data, as part of an effort to gain a better understanding of the Paleozoic rocks beneath Yucca Flat in support of groundwater modeling.

Observations are made in the field with gravity meters at new locations and at reoccupations of previously established gravity \"stations.\" This report illustrates an interactively-prompted series of steps needed to convert gravity \"readings\" to values that are tied to established gravity datums and includes computer programs to implement those steps. Inasmuch as individual gravity readings have small variations, gravity-meter (instrument) drift may not be smoothly variable, and acommodations may be needed for ties to previously established stations, the reduction process is iterative. Decision-making by the program user is prompted by lists of best values and graphical displays.\n\nNotes about irregularities of topography, which affect the value of observed gravity but are not shown in sufficient detail on topographic maps, must be recorded in the field. This report illustrates ways to record field notes (distances, heights, and slope angles) and includes computer programs to convert field notes to gravity terrain corrections.\n\nThis report includes approaches that may serve as models for other applications, for example: portrayal of system flow; style of quality control to document and validate computer applications; lack of dependence on proprietary software except source code compilation; method of file-searching with a dwindling list; interactive prompting; computer code to write directly in the PostScript (Adobe Systems Incorporated) printer language; and high-lighting the four-digit year on the first line of time-dependent data sets for assured Y2K compatibility.\n\nComputer source codes provided are written in the Fortran scientific language. In order for the programs to operate, they first must be converted (compiled) into an executable form on the user's computer. Although program testing was done in a UNIX (tradename of American Telephone and Telegraph Company) computer environment, it is anticipated that only a system-dependent date-and-time function may need to be changed for adaptation to other computer platforms that accept standard Fortran code.d del iliscipit volorer sequi ting etue feum zzriliquatum zzriustrud esenibh ex esto esequat.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr00140","issn":"0094-9140","usgsCitation":"Plouff, D., 2000, Field estimates of gravity terrain corrections and Y2K-compatible method to convert from gravity readings with multiple base stations to tide- and long-term drift-corrected observations: U.S. Geological Survey Open-File Report 2000-140, Report: i, 35 p.; Programs TAR: 1 .rar file, https://doi.org/10.3133/ofr00140.","productDescription":"Report: i, 35 p.; Programs TAR: 1 .rar file","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":1618,"rank":3,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/0140/","linkFileType":{"id":5,"text":"html"}},{"id":281405,"rank":2,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2000/0140/programs.tar"},{"id":53346,"rank":4,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0140/pdf/of00-140.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":155520,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0140/report-thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49fce4b07f02db5f59c9","contributors":{"authors":[{"text":"Plouff, Donald","contributorId":94657,"corporation":false,"usgs":true,"family":"Plouff","given":"Donald","email":"","affiliations":[],"preferred":false,"id":191488,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":23992,"text":"ofr00146 - 2000 - Deformation along the San Andreas Fault south of the coseismic and postseismic October 18, 1989, Loma Prieta ML 7.1 earthquake rupture","interactions":[],"lastModifiedDate":"2012-02-02T00:08:10","indexId":"ofr00146","displayToPublicDate":"2000-10-01T00:00:00","publicationYear":"2000","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2000-146","title":"Deformation along the San Andreas Fault south of the coseismic and postseismic October 18, 1989, Loma Prieta ML 7.1 earthquake rupture","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey,","doi":"10.3133/ofr00146","issn":"0094-9140","usgsCitation":"Mueller, R.J., and Johnston, M.J., 2000, Deformation along the San Andreas Fault south of the coseismic and postseismic October 18, 1989, Loma Prieta ML 7.1 earthquake rupture: U.S. Geological Survey Open-File Report 2000-146, 36 p., :ill., maps ;28 cm., https://doi.org/10.3133/ofr00146.","productDescription":"36 p., :ill., maps ;28 cm.","costCenters":[],"links":[{"id":156271,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0146/report-thumb.jpg"},{"id":53179,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0146/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abbe4b07f02db672459","contributors":{"authors":[{"text":"Mueller, Robert J.","contributorId":76776,"corporation":false,"usgs":true,"family":"Mueller","given":"Robert","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":191111,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnston, M.

Two sedimentary units are recognized; the Oligocene and Miocene Pantano(?) Formation and an unnamed upper Miocene through lower Pleistocene unit termed basin fill. \r\n\r\nThe complete Bouguer gravity anomaly map shows that there are three major structural subbasins in the upper San Pedro basin north of the international border with Mexico. The Tombstone subbasin is north of Tombstone, and two more are located north and south of Sierra Vista, respectively. This report concentrates on the two subbasins north and south of Sierra Vista. The northern subbasin (termed the Huachuca City subbasin) extends from east of Huachuca City to northeast of Whetstone, and the southern subbasin (termed the Palominas subbasin) extends southward from a line between Nicksville and Hereford to the border. The locations and shapes of these subbasins, thickness of basin fill, and depth to bedrock were estimated using a procedure involving interpolation of (1) the density functions derived in this study, (2) stratigraphic data from water wells, and (3) a residual gravity anomaly grid obtained by subtracting the gravity effects of the bedrock ranges bordering the basin from the complete Bouguer gravity anomaly. \r\n\r\nThis procedure indicates that the subbasins are shallow and contain significant thicknesses of the Pantano(?) Formation in addition to the overlying younger basin fill. The maximum depth to bedrock is about 1,700 m in the Palominas subbasin and 800m in the Huachuca City subbasin; the basin-fill unit occupies the upper 250-350 m in general with local thickenings exceeding 1,000 m in the Palominas subbasin. An east-west trending buried bedrock high beneath Fort Huachuca, Sierra Vista, and Charleston separates the subbasins. The depth to bedrock over this high is 200-500 m and the basin-fill unit ranges from 100 to 200 m thick there. A number of previously unrecognized faults were identified and the lengths of some of the known faults were extended based on reconnaissance geologic mapping, study of driller's logs, interpretation of aerial photographs and thematic mapper satellite images, and inspection of contoured gravity and aeromagnetic anomaly data. Many faults that segment the main San Pedro basin and shape the boundaries of the subbasins are apparently pre-existing faults that have been reactivated by Basin and Range extension.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr00138","issn":"0094-9140","usgsCitation":"Gettings, M.E., and Houser, B.B., 2000, Depth to bedrock in the upper San Pedro Valley, Cochise County, southeastern Arizona: U.S. Geological Survey Open-File Report 2000-138, Online only, https://doi.org/10.3133/ofr00138.","productDescription":"Online only","costCenters":[],"links":[{"id":153794,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":1327,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/of00-138/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ab1e4b07f02db66e818","contributors":{"authors":[{"text":"Gettings, M.

In September 1999, water-to-vapor diffusion samplers were placed in the bottom sediments of waterways adjacent to the site to identify possible contaminated ground-water discharge areas. The approximate12-acre site is a narrow stretch of land between the eastern bank of the Woonasquatucket River, downstream from the U.S. Route 44 bridge and a former mill raceway. The samplers were placed along a 2,250-foot reach of the Woonasquatucket River, in the former mill raceway several hundred feet to the east and parallel to the river, and in a cross channel between the river and former mill raceway.\u000B\u000BVolatile organic compounds were detected in 84 of the 104 water-to-vapor diffusion samplers retrieved. Trichloroethylene and tetrachloro-ethylene were the principal volatile organic compounds detected. The highest vapor concentrations measured for these two chemicals were from diffusion samplers located along an approximate 100-foot reach of the Woonasquatucket River about 500 feet downstream of the bridge; here trichloroethylene and tetrachloroethylene vapor concentrations ranged from about 2,000 to 180,000 and 1,600 to 1,400,000 parts per billion by volume, respectively. Upstream and downstream from this reach and along the former mill raceway, trichloroethylene and tetrachloroethylene vapor concentrations from the diffusion samples were generally less than 100 parts per billion by volume. Along the lower reaches of the river and mill raceway, however, and in the cross channel, vapor concentrations of trichloroethylene exceeded 100 parts per billion by volume and tetrachloroethylene exceeded 1,000 parts per billion by volume in several diffusion samples. Although diffusion sample vapor concentrations are higher than water concentrations in surface waters and in ground water, and they should only be interpreted qualitatively as relative values, these values provide important information as to potential discharge areas of contaminants.","language":"ENGLISH","publisher":"U.S. Department of the Interior, U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/ofr00276","issn":"0094-9140","usgsCitation":"Church, P.E., Lyford, F.P., and Clifford, S., 2000, Distribution of selected volatile organic compounds determined with water-to-vapor diffusion samplers at the interface between ground water and surface water, Centredale Manor site, North Providence, Rhode Island, September 1999: U.S. Geological Survey Open-File Report 2000-276, iv, 9 p. :ill., map ;28 cm., https://doi.org/10.3133/ofr00276.","productDescription":"iv, 9 p. :ill., map ;28 cm.","costCenters":[],"links":[{"id":1455,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr00276","linkFileType":{"id":5,"text":"html"}},{"id":155152,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a29e4b07f02db611e3c","contributors":{"authors":[{"text":"Church, Peter E.","contributorId":99178,"corporation":false,"usgs":true,"family":"Church","given":"Peter","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":188741,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lyford, Forest P.","contributorId":43334,"corporation":false,"usgs":true,"family":"Lyford","given":"Forest","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":188739,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Clifford, Scott","contributorId":63042,"corporation":false,"usgs":true,"family":"Clifford","given":"Scott","email":"","affiliations":[],"preferred":false,"id":188740,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":23029,"text":"ofr00114 - 2000 - Analytical results for total-digestions, EPA-1312 leach, and net acid production for twenty-three abandoned metal-mining related wastes in the Boulder River watershed, northern Jefferson County, Montana","interactions":[],"lastModifiedDate":"2020-02-23T17:22:42","indexId":"ofr00114","displayToPublicDate":"2000-10-01T00:00:00","publicationYear":"2000","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2000-114","title":"Analytical results for total-digestions, EPA-1312 leach, and net acid production for twenty-three abandoned metal-mining related wastes in the Boulder River watershed, northern Jefferson County, Montana","docAbstract":"Metal-mining related wastes in the Boulder River basin study area in northern Jefferson County, Montana, have been implicated in their detrimental effects on water quality with regard to acid generation and toxic-metal solubilization during snow melt and storm water runoff events. This degradation of water quality is defined chiefly by the “Class 1 Aquatic Life Standards” that give limits for certain dissolved metal concentrations according to water alkalinity.
Veins enriched in base- and precious metals were explored and mined in the Basin, Cataract Creek, and High Ore Creek drainages over a period of more than 70 years. Extracted minerals included galena, sphalerite, pyrite, chalcopyrite, tetrahedrite and arsenopyrite. Most of the metal-mining wastes in the study area were identified and described by the Montana Bureau of Mines and Geology. In 1997, the U.S. Geological Survey collected 20 composite samples of mine-dump or tailings waste from ten sites in the Basin and Cataract Creek drainages, and two samples from one site in the High Ore Creek drainage. Desborough and Fey presented data concerning acid generation potential, mineralogy, concentrations of certain metals by energy-dispersive X-ray fluorescence (EDXRF), and trace-element leachability of mine and exploration wastes from the ten sites of the Basin and Cataract Creek drainages. The present report presents total-digestion major- and trace-element analyses, net acid production (NAP), and results from the EPA-1312 synthetic precipitation leach procedure (SPLP) performed on the same composite samples from the ten sites from the Basin and Cataract Creek drainages, and two composite samples from the site in the High Ore Creek drainage.

This program, SUDS2SEGY, converts and combines ASCII files created using SUDS2ASC Version 2.60, to a single SEGY file.
\nSUDS2ASC has been used previously to create an ASCII file of three-component seismic data for an individual recording station. However, many seismic processing packages have difficulty reading in ASCII data. In addition, it may be cumbersome to process a separate file for each recording station, particularly if traces from different recording stations contain a different number of data samples and/or a different start time.
\nThis new program - SUDS2SEGY - combines these recording station files into a single SEGY file. In addition, SUDS2SEGY normalizes the trace times so that each trace starts at a given time and consists of a fixed number of samples. This normalization allows seismic data from many different stations to be read in as a single \"data gather\". SUDS2SEGY also produces a report summarizing the offset and maximum absolute amplitude for each component in a station file. These data are output separately to an ASCII file and can be subsequently input to a plotting package.

The report is stored as several digital files, in ARC export (uncompressed) format for the database, and Postscript and PDF formats for the map images. Several of the source data layers for the images have already been released in other publications by the USGS and are available for downloading on the Internet. These source layers are not included in this digital database, but rather a reference is given for the web site where the data can be found in digital format. The exported ARC coverages and grids lie in UTM zone 10 projection. The pamphlet, which only describes the content and character of the digital map database, is included as Postscript, PDF, and ASCII text files and is also available on paper as USGS Open-File Report 00-127. The full versatility of the spatial database is realized by importing the ARC export files into ARC/INFO or an equivalent GIS. Other GIS packages, including MapInfo and ARCVIEW, can also use the ARC export files. The Postscript map image can be used for viewing or plotting in computer systems with sufficient capacity, and the considerably smaller PDF image files can be viewed or plotted in full or in part from Adobe ACROBAT software running on Macintosh, PC, or UNIX platforms.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr00127","issn":"0094-9140","usgsCitation":"Brabb, E.E.,

Paleoecological changes in ostracode, mollusc, and foraminifer assemblages show that core SEI297-FB-1 can be divided into three distinctly different zones, which together provide evidence for distinct changes in historical environmental conditions at Featherbed Bank. \r\n\r\nAssemblages from fossil biotic communities within zone 1, representing approximately 1440 to 1550 AD, are characterized by open-marine biota with relatively limited numbers of epiphytic biota. Molluscan faunal indicators suggest the sediment was capable of supporting infaunal organisms and that faunal richness was relatively limited during this time period. \r\n\r\nA change in the biotic community occurred around 1550 AD and continued until the late 1800's distinguishing zone 2. Fossil biotic indicators from zone 2 show a strong dominance of epiphytic organisms within all of the biotic communities examined. Foraminifers, molluscs, and ostracodes capable of subsisting in salinities slightly lower than normal marine begin to flourish in this time period, and there is a marked decline in infaunal molluscs. \r\n\r\nZone 2 assemblages are replaced around 1900 AD by increased numbers of organisms that typify open-marine conditions and a return to decreased epiphytic assemblages, similar to zone 1. Zone 3 assemblages, however, show some strong dissimilarities from zone 1, including limited infaunal molluscs, increased abundances of the ostracode Malzella floridana, and a significant increase in molluscan faunal richness.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr00191","issn":"0094-9140","usgsCitation":"Stone, J., Cronin, T.M., Brewster-Wingard, G., Ishman, S., Wardlaw, B.R., and Holmes, C.W., 2000, A paleoecologic reconstruction of the history of Featherbed Bank, Biscayne National Park, Biscayne Bay, Florida: U.S. Geological Survey Open-File Report 2000-191, v, 36 p., https://doi.org/10.3133/ofr00191.","productDescription":"v, 36 p.","costCenters":[{"id":27821,"text":"Caribbean-Florida Water Science Center","active":true,"usgs":true}],"links":[{"id":51468,"rank":299,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0191/report.pdf","text":"Report","size":"3.46 MB","linkFileType":{"id":1,"text":"pdf"},"description":"OFR 00-191"},{"id":153729,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0191/report-thumb.jpg"}],"country":"United States","state":"Florida","otherGeospatial":"Biscayne National Park","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -80.45425415039061,\n 25.0482805352365\n ],\n [\n -80.14938354492188,\n 25.0482805352365\n ],\n [\n -80.14938354492188,\n 25.521375362412332\n ],\n [\n -80.45425415039061,\n 25.521375362412332\n ],\n [\n -80.45425415039061,\n 25.0482805352365\n ]\n ]\n ]\n }\n }\n ]\n}","contact":"Caribbean-Florida Water Science Center
