Widespread selection of this method may be more the result of its ease of use and interpretation rather than comparisons with alternative methods. A comparison of the weights-of-evidence method to probabilistic neural networks is performed here with data from Chisel Lake-Andeson Lake, Manitoba, Canada. Each method is designed to estimate the probability of belonging to learned classes where the estimated probabilities are used to classify the unknowns. Using these data, significantly lower classification error rates were observed for the neural network, not only when test and training data were the same (0.02 versus 23%), but also when validation data, not used in any training, were used to test the efficiency of classification (0.7 versus 17%). Despite these data containing too few deposits, these tests of this set of data demonstrate the neural network's ability at making unbiased probability estimates and lower error rates when measured by number of polygons or by the area of land misclassified. For both methods, independent validation tests are required to ensure that estimates are representative of real-world results. Results from the weights-of-evidence method demonstrate a strong bias where most errors are barren areas misclassified as deposits. The weights-of-evidence method is based on Bayes rule, which requires independent variables in order to make unbiased estimates. The chi-square test for independence indicates no significant correlations among the variables in the Chisel Lake–Andeson Lake data. However, the expected number of deposits test clearly demonstrates that these data violate the independence assumption. Other, independent simulations with three variables show that using variables with correlations of 1.0 can double the expected number of deposits as can correlations of −1.0. Studies done in the 1970s on methods that use Bayes rule show that moderate correlations among attributes seriously affect estimates and even small correlations lead to increases in misclassifications. Adverse effects have been observed with small to moderate correlations when only six to eight variables were used. Consistent evidence of upward biased probability estimates from multivariate methods founded on Bayes rule must be of considerable concern to institutions and governmental agencies where unbiased estimates are required. In addition to increasing the misclassification rate, biased probability estimates make classification into deposit and nondeposit classes an arbitrary subjective decision. The probabilistic neural network has no problem dealing with correlated variables—its performance depends strongly on having a thoroughly representative training set. Probabilistic neural networks or logistic regression should receive serious consideration where unbiased estimates are required. The weights-of-evidence method would serve to estimate thresholds between anomalies and background and for exploratory data analysis.</span></p>","language":"English","publisher":"Springer","doi":"10.1023/A:1021606417010","usgsCitation":"Singer, D.A., and Kouda, R., 1999, A comparison of the weights-of-evidence method and probabilistic neural networks: Natural Resources Research, v. 8, no. 4, p. 287-298, https://doi.org/10.1023/A:1021606417010.","productDescription":"12 p.","startPage":"287","endPage":"298","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":354373,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"8","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5b15919ae4b092d9651e21f2","contributors":{"authors":[{"text":"Singer, Donald A. dsinger@usgs.gov","contributorId":5601,"corporation":false,"usgs":true,"family":"Singer","given":"Donald","email":"dsinger@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":735969,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kouda, Ryoichi","contributorId":198036,"corporation":false,"usgs":false,"family":"Kouda","given":"Ryoichi","email":"","affiliations":[],"preferred":false,"id":735970,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Previous reconstructions of late Pleistocene climates from packrat midden assemblages in this region (Spaulding, 1985) assessed the minimum climatic differences from today by estimating the present-day climatic differences between the fossil midden sites and the nearest current occurrences of key plant species recovered from the Pleistocene middens. From this approach Spaulding (1985) concluded that although late Pleistocene temperatures were considerably below those of today, only modest increases in precipitation (relative to today) were necessary for these plant species to survive in the current Mojave Desert during the late Pleistocene.</p><p>Spaulding's approach provided \"state-of-the-art\" results from an intensive careful examination of the best data available at the time. However, data and techniques developed since the mid-1980s suggest that there are two possible short-comings to this approach: 1) the use of lowest elevational and (frequently) most southerly occurrences of key plant species results in <u>minimal</u> estimates of the differences between Pleistocene and present-day climates, and 2) the instrumental climate data set available to Spaulding was limited in duration, non-standard in its method of collection, and indicated a modern climate wetter than the long-term historic mean, which resulted in relatively small apparent differences between late Pleistocene and present-day mean annual precipitation levels. In this report we use a more standard (close to the long-term mean) modern calibration period and a modern plant distribution data set that permits us to identify modern analogues for the Pleistocene vegetation. This reexamination permits a more robust reconstruction of the past climate, and results in estimates of mean annual temperature for the glacial maximum at Yucca Mountain that are 1.0° to 1.4° C warmer than those of Spaulding, and estimates of mean annual precipitation that are 60 mm or more higher than his.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99338","issn":"0094-9140","usgsCitation":"Thompson, R., Anderson, K.H., and Bartlein, P., 1999, Quantitative paleoclimatic reconstructions from late Pleistocene plant macrofossils of the Yucca Mountain region: U.S. Geological Survey Open-File Report 99-338, 38 p., https://doi.org/10.3133/ofr99338.","productDescription":"38 p.","costCenters":[],"links":[{"id":1923,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/ofr-99-0338/p1.html","linkFileType":{"id":5,"text":"html"}},{"id":53699,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0338/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":157741,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0338/report-thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a86e4b07f02db64db54","contributors":{"authors":[{"text":"Thompson, R.S.","contributorId":106516,"corporation":false,"usgs":true,"family":"Thompson","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":192370,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Anderson, K.

Because of the extreme oxygen sensitivity of these organisms and the inherent limitations of cultural techniques, an accurate biomass value is very difficult to obtain. We standardized a simple method for estimating methanogen biomass in a variety of environmental matrices. In this procedure we used the thiol biomarker coenzyme M (CoM) (2-mercaptoethanesulfonic acid), which is known to be present in all methanogenic bacteria. A high-performance liquid chromatography-based method for detecting thiols in pore water (A. Vairavamurthy and M. Mopper, Anal. Chim. Acta 78:363–370, 1990) was modified in order to quantify CoM in pure cultures, sediments, and sewage water samples. The identity of the CoM derivative was verified by using liquid chromatography-mass spectroscopy. The assay was linear for CoM amounts ranging from 2 to 2,000 pmol, and the detection limit was 2 pmol of CoM/ml of sample. CoM was not adsorbed to sediments. The methanogens tested contained an average of 19.5 nmol of CoM/mg of protein and 0.39 ± 0.07 fmol of CoM/cell. Environmental samples contained an average of 0.41 ± 0.17 fmol/cell based on most-probable-number estimates. CoM was extracted by using 1% tri-(</span><i>N</i><span>)-butylphosphine in isopropanol. More than 90% of the CoM was recovered from pure cultures and environmental samples. We observed no interference from sediments in the CoM recovery process, and the method could be completed aerobically within 3 h. Freezing sediment samples resulted in 46 to 83% decreases in the amounts of detectable CoM, whereas freezing had no effect on the amounts of CoM determined in pure cultures. The method described here provides a quick and relatively simple way to estimate methanogenic biomass.</span></p>","language":"English","publisher":"American Society for Microbiology","doi":"10.1128/AEM.65.12.5541-5545.1999","usgsCitation":"Elias, D.A., Krumholz, L.R., Tanner, R.S., and Suflita, J.M., 1999, Estimation of methanogen biomass via quantitation of coenzyme M: Applied and Environmental Microbiology, v. 65, no. 12, p. 5541-5545, https://doi.org/10.1128/AEM.65.12.5541-5545.1999.","productDescription":"5 p.","startPage":"5541","endPage":"5545","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":479408,"rank":2,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1128/aem.65.12.5541-5545.1999","text":"External Repository"},{"id":338402,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"65","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58da253ae4b0543bf7fda85d","contributors":{"authors":[{"text":"Elias, Dwayne A.","contributorId":189299,"corporation":false,"usgs":false,"family":"Elias","given":"Dwayne","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":686365,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Krumholz, Lee R.","contributorId":187679,"corporation":false,"usgs":false,"family":"Krumholz","given":"Lee","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":686366,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Tanner, Ralph S.","contributorId":189884,"corporation":false,"usgs":false,"family":"Tanner","given":"Ralph","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":686367,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Suflita, Joseph M.","contributorId":187604,"corporation":false,"usgs":false,"family":"Suflita","given":"Joseph","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":686368,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The coal-bearing region extends westward from Alabama and Mississippi, across Louisiana to the northern part of the Mississippi Embayment, and then southward to eastern Arkansas, Texas and northern Mexico (fig. 1). Most of the coal currently mined in Texas is lignite from the upper part of the Wilcox Group (Paleocene-Eocene) and, in Louisiana, lignite is mined from the lower part of the Wilcox (fig. 2). Gulf Coast coal is used primarily as fuel for mine-mouth electric plants. On this field trip we will visit the only two non-Wilcox coal mining intervals in the Texas-Louisiana Coastal Plain; these include the San Pedro - Santo Tomas bituminous cannel-like coal zone of the Eocene Claiborne Group, and the San Miguel lignite coal zone of the Eocene Jackson Group (fig. 2). Other coal-mining areas in northern Mexico are currently producing bituminous coal from the Cretaceous Olmos Formation of the Navaro Group (fig. 2).</p>","language":"English","publisher":"U.S.

Ongoing analyses of the \r\ncentral portion of the Middle Rio Grande Basin by the U.S. Geological\r\nSurvey (USGS) in cooperation with the City of Albuquerque and \r\nother agencies have shown that ground water in the basin is not as \r\nreadily accessible as earlier studies indicated. A more complete \r\ncharacterization of the ground-water resources of the entire Middle\r\nRio Grande Basin is hampered by a scarcity of data in the \r\nnorthern and southern areas of the basin.\r\n\r\nThe USGS Middle Rio Grande Basin study is a 5-year effort by the \r\nUSGS and other agencies to improve the understanding of the \r\nhydrology, geology, and land-surface characteristics of the Middle\r\nRio Grande Basin. The primary objective of this study is to \r\nimprove the understanding of the water resources of the basin. Of \r\nparticular interest is to determine the extent of hydrologic\r\nconnection between the Rio Grande and the Santa Fe Group aquifer. \r\nAdditionally, ground-water quality affects the availability of \r\nwater supplies in the basin. Improving the existing USGS-constructed\r\nground-water flow model of the Middle Rio Grande Basin will \r\nintegrate all the various tasks that improve our knowledge of the \r\nvarious components of the Middle Rio Grande water budget. Part \r\nof this improvement will be accompanied by extended knowledge of \r\nthe aquifer system beyond the Albuquerque area into the northern \r\nand southern reaches of the basin. Other improvements will be \r\nbased on understanding gained through process-oriented research \r\nand improved geologic characterization of the deposits. The USGS \r\nand cooperating agencies will study the hydrology, geology, and \r\nland-surface characteristics of the basin to provide the scientific\r\ninformation needed for water-resources management and for managers \r\nto plan for water supplies needed for a growing population.\r\n\r\nTo facilitate exchange of information among the scientists working\r\non the Middle Rio Grande Basin study, yearly technical meetings\r\nhave been held for each of the first 3 years of the anticipated \r\n5-year study. These meetings provide an opportunity to present \r\nresearch results and plan new field efforts. This report documents \r\nthe results of research presented at the third annual technical \r\nworkshop held in Albuquerque, New Mexico, February 24-25, 1999.\r\n\r\nThe report is organized into this introduction and five chapters \r\nthat focus on Middle Rio Grande Basin study investigations in \r\nprogress in the Middle Rio Grande Basin. The first chapter \r\ndescribes geographic data and analysis efforts in the basin. The \r\nsecond chapter details work being done on the hydrogeologic and \r\ngeologic framework of the basin. The third chapter describes \r\nstudies on ground-water recharge in the basin. The fourth chapter \r\nprovides details on the research on the ground-water flow system \r\nin the basin, including modeling efforts. The fifth chapter is \r\ndevoted to an overview of New Mexico District Cooperative Program \r\nstudies in the basin.\r\n\r\nThe information in this report presents preliminary results of an \r\nevolving study. As the study progresses and individual projects \r\npublish their results in more detail, the USGS hopes to expand the \r\nscientific basis needed for management decisions regarding the \r\nMiddle Rio Grande Basin.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/ofr99203","issn":"0094-9140","usgsCitation":"Bartolino, J.R., 1999, U.S. Geological Survey middle Rio Grande basin study; proceedings of the third annual workshop, Albuquerque, New Mexico, February 24-25, 1999: U.S. Geological Survey Open-File Report 99-203, vi, 95 p. ill., maps ;28 cm., https://doi.org/10.3133/ofr99203.","productDescription":"vi, 95 p. ill., maps ;28 cm.","costCenters":[],"links":[{"id":156000,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0203/report-thumb.jpg"},{"id":51667,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0203/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e2e4b07f02db5e4b57","contributors":{"authors":[{"text":"Bartolino, James R. 0000-0002-2166-7803 jrbartol@usgs.gov","orcid":"https://orcid.org/0000-0002-2166-7803","contributorId":2548,"corporation":false,"usgs":true,"family":"Bartolino","given":"James","email":"jrbartol@usgs.gov","middleInitial":"R.","affiliations":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"preferred":true,"id":187720,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This regional increase in metal concentrations coincides with a dramatic change in landform wherein high concentrations of metals in stream sediments appear to correlate directly with areas of high elevations and steep slopes in the Beaver Peak quadrangle. Robust erosion combined with high flow rates in streams from these higher elevations are envisaged to have contributed significantly to increased metal concentrations in the stream sediments by an enhanced presence of minerals with high specific gravities and a correspondingly diminished presence of minerals with low specific gravities. Minerals with low specific gravities probably have been preferentially flushed down stream because of high transporting capacities for sediment by streams in the Beaver Peak quadrangle. In addition, the Carlin trend, a generally northwest-alignment of gold deposits in the Santa Renia Fields quadrangle, is well outlined by arsenic concentrations that include a maximum of approximately 54 parts per million. Further, a weakly developed distal-to-proximal metal zonation towards these gold deposits appears to be defined respectively in plots showing distributions of thallium, arsenic, antimony, and zinc. A broad area of high metal concentrations—including sharply elevated abundances of Ag, As, Au, Cd, Co, Cu, Mn, Ni, P, Sb, Sc, Te, V, and especially Zn—near the southeast corner of the Beaver Peak quadrangle primarily could be the result of stratiform mineralized rocks in the Ordovician Vinini Formation or Devonian Slaven Chert, or the result of a subsequent Mesozoic or Tertiary epigenetic overprint.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99341","issn":"0566-8174","usgsCitation":"Theodore, T., Kotlyar, B.B., Berger, V.I., Moring, B.C., Singer, D.A., and Edstrom, S.A., 1999, Geochemistry of stream-sediment samples from the Santa Renia Fields and Beaver Peak quadrangles, northern Carlin Trend, Nevada: U.S. Geological Survey Open-File Report 99-341, Report: iv, 105 p.; Data: XLS; Data only: PDF, https://doi.org/10.3133/ofr99341.","productDescription":"Report: iv, 105 p.; Data: XLS; Data only: PDF","numberOfPages":"109","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":153975,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0341/report-thumb.jpg"},{"id":1227,"rank":4,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/0341/","linkFileType":{"id":5,"text":"html"}},{"id":284893,"rank":2,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/1999/0341/pdf/SRF_BPGeochem.pdf"},{"id":284892,"rank":3,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/1999/0341/SRF_BPGeochem.xls"},{"id":51299,"rank":5,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0341/pdf/OF99-341.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Nevada","otherGeospatial":"Beaver Peak, Santa Reina Fields","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.5,41.0 ], [ -116.5,41.125 ], [ -116.25,41.125 ], [ -116.25,41.0 ], [ -116.5,41.0 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5b08e4b0b290850f9c00","contributors":{"authors":[{"text":"Theodore, Ted G.","contributorId":57840,"corporation":false,"usgs":true,"family":"Theodore","given":"Ted G.","affiliations":[],"preferred":false,"id":185773,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kotlyar, Boris B.","contributorId":35376,"corporation":false,"usgs":true,"family":"Kotlyar","given":"Boris","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":185771,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Berger, Vladimir I.","contributorId":15246,"corporation":false,"usgs":true,"family":"Berger","given":"Vladimir","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":185770,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Moring, Barry C. 0000-0001-6797-9258 moring@usgs.gov","orcid":"https://orcid.org/0000-0001-6797-9258","contributorId":2794,"corporation":false,"usgs":true,"family":"Moring","given":"Barry","email":"moring@usgs.gov","middleInitial":"C.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":185768,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Singer, Donald A. dsinger@usgs.gov","contributorId":5601,"corporation":false,"usgs":true,"family":"Singer","given":"Donald","email":"dsinger@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":185769,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Edstrom, Sven A.","contributorId":50816,"corporation":false,"usgs":true,"family":"Edstrom","given":"Sven","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":185772,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}
