The time-dependent calibration record for Landsat-5 TM has been placed on the same radiometric scale as the Landsat-7 enhanced thematic mapper plus (ETM+). It has been implemented in the National Landsat Archive Production Systems (NLAPS) in use in North America. This paper documents the results of this collaborative effort and the specifications for the related calibration processing algorithms. The specifications include (i) anchoring of the Landsat-5 TM calibration record to the Landsat-7 ETM+ absolute radiometric calibration, (ii) new time-dependent calibration processing equations and procedures applicable to raw Landsat-5 TM data, and (iii) algorithms for recalibration computations applicable to some of the existing processed datasets in the North American context. The cross-calibration between Landsat-5 TM and Landsat-7 ETM+ was achieved using image pairs from the tandem-orbit configuration period that was programmed early in the Laridsat-7 mission. The time-dependent calibration for Landsat-5 TM is based on a detailed trend analysis of data from the on-board internal calibrator. The new lifetime radiometric calibration record for Landsat-5 will overcome problems with earlier product generation owing to inadequate maintenance and documentation of the calibration over time and will facilitate the quantitative examination of a continuous, near-global dataset at 30-m scale that spans almost two decades.</p>","language":"English","publisher":"Canadian Aeronautics and Space Institute","doi":"10.5589/m04-022","issn":"07038992","usgsCitation":"Teillet, P., Helder, D., Ruggles, T., Landry, R., Ahern, F., Higgs, N., Barsi, J., Chander, G., Markham, B.L., Barker, J.L., Thome, K.J., Schott, J.R., and Palluconi, F.D., 2004, A definitive calibration record for the Landsat-5 thematic mapper anchored to the Landsat-7 radiometric scale: Canadian Journal of Remote Sensing, v. 30, no. 4, p. 631-643, https://doi.org/10.5589/m04-022.","productDescription":"13 p.","startPage":"631","endPage":"643","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":233955,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"30","issue":"4","noUsgsAuthors":false,"publicationDate":"2014-06-02","publicationStatus":"PW","scienceBaseUri":"5059e3ade4b0c8380cd46184","contributors":{"authors":[{"text":"Teillet, P.M.","contributorId":23717,"corporation":false,"usgs":true,"family":"Teillet","given":"P.M.","email":"","affiliations":[],"preferred":false,"id":410805,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Helder, D.

Prior investigations suggested that evidence for late Pleistocene eolian activity in the dune field was lacking. However, luminescence ages from eolian sand of ???15,000 yr, as well as Folsom (12,950-11,950 cal yr B.P.) and Agate Basin (12,600-10,700 cal yr) artifacts overlying eolian sand, indicate the dune field existed at least during the latest Pleistocene, with initial eolian sedimentation probably occurring under a dry periglacial climate. The period between ???13,000 and 8900 cal yr B.P. was characterized by relatively slow eolian sedimentation concomitant with soil formation. Erosion occurred between ???8182 and 6600 cal yr B.P. on the upwind region of the dune field, followed by relative stability and soil formation between ???5900 and 2700 cal yr B.P. The first of at least two latest Holocene episodes of eolian sedimentation occurred between ???2000 and 1500 yr, followed by a brief (???500 yr) episode of soil formation; a second episode of sedimentation, occurring by at least ???700 yr, may coincide with a hypothesized Medieval warm period. Recent stabilization of the western Killpecker Dunes likely occurred during the Little Ice Age (???350-100 yr B.P.). The eolian chronology of the western Killpecker Dunes correlates reasonably well with those of other major dune fields in the Wyoming Basin, suggesting that dune field reactivation resulted primarily due to departures toward aridity during the late Quaternary. Similar to dune fields on the central Great Plains, dune fields in the Wyoming Basin have been active under a periglacial climate during the late Pleistocene, as well as under near-modern conditions during the latest Holocene. ?? 2003 University of Washington.

A minimum structure P wave velocity model is constructed using 175,000 first arrival travel times picked from data recorded by 58 temporary onshore stations. The model details forearc crustal structures related to terrane accretion and subsequent basin formation to a depth of about 10 km. The Metchosin igneous complex (correlative with the Eocene Crescent-Siletz Terrane in Washington) is imaged as a laterally extensive WNW trending high-velocity anomaly underlying southernmost Vancouver Island and much of the Strait of Juan du Fuca. Northeast of the Strait of Georgia, the southwesterly dip of the contact between the Wrangellia terrane rocks of Vancouver Island and the Coast Plutonic Complex suggests Wrangellia rocks are down-faulted against the plutonic complex. At the southwestern end of the Strait of Juan de Fuca, the 50 km long WNW trending Clallam basin has a maximum thickness of 5-6 km. Near the eastern end of the Strait of Juan de Fuca, Port Townsend basin has an inferred thickness of approximately 4-5 km. The southern end of the 9 km thick Georgia basin is bounded by a high-velocity basement ridge. Beneath the Strait of Georgia, clusters of well-located earthquakes have a prominent NW trend and coincide spatially with rapid lateral velocity changes. Clusters of microearthquakes there are associated with the intersection of several east trending structural highs within this NW trend.

Using mark-recapture (four species) and trap capture (eight species) data, we examined relationships between three attributes of movement and 15 ecological variables. The probability of emigrating from a reach was positively related to intermittency (one species) and body size (one species) and negatively related to distance from the mainstem creek (two species) and habitat complexity (one species). The number of fish moving upstream through traps was positively related to increases in flow (five species), day length (three species), and water temperature (two species); the number moving through downstream traps was positively associated with increases in flow (three species). Distance moved was greater for fish moving through unsuitable reaches (one species). Floods have a pervasive effect on fish movement, and human activities that affect flows will have widespread implications. The importance of other factors varies interspecifically, which may translate into variation in persistence and colonization rates. For example, species that exhibit reach fidelity in complex habitats may increase movement if habitats are homogenized. These species may suffer population declines because of the cost of increased movement and may ultimately be replaced by ecological generalists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Fisheries and Aquatic Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/F04-096","issn":"0706652X","usgsCitation":"Albanese, B., Angermeier, P., and Dorai-Raj, S., 2004, Ecological correlates of fish movement in a network of Virginia streams: Canadian Journal of Fisheries and Aquatic Sciences, v. 61, no. 6, p. 857-869, https://doi.org/10.1139/F04-096.","startPage":"857","endPage":"869","numberOfPages":"13","costCenters":[],"links":[{"id":209329,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/F04-096"},{"id":235636,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"61","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a054de4b0c8380cd50d44","contributors":{"authors":[{"text":"Albanese, B.","contributorId":47136,"corporation":false,"usgs":true,"family":"Albanese","given":"B.","email":"","affiliations":[],"preferred":false,"id":412975,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Angermeier, P.

Yosemite National Park is one of the largest and best-known parks in the United States, harbouring significant cultural and ecological resources. Effective management of non-natives would be greatly assisted by information on their potential distribution that can be generated by predictive modelling techniques. Our goal was to identify key environmental factors that were correlated with the percent cover of non-native species and then develop a predictive model using the Genetic Algorithm for Rule-set Production technique. We performed a series of analyses using community-level data on species composition in 236 plots located throughout the park. A total of 41 non-native species were recorded which occurred in 23.7% of the plots. Plots with non-natives occurred most frequently at low- to mid-elevations, in flat areas with other herbaceous species. Based on the community-level results, we selected elevation, slope, and vegetation structure as inputs into the GARP model to predict the environmental niche of non-native species. Verification of results was performed using plot data reserved from the model, which calculated the correct prediction of non-native species occurrence as 76%. The majority of the western, lower-elevation portion of the park was predicted to have relatively low levels of non-native species occurrence, with highest concentrations predicted at the west and south entrances and in the Yosemite Valley. Distribution maps of predicted occurrences will be used by management to: efficiently target monitoring of non-native species, prioritize control efforts according to the likelihood of non-native occurrences, and inform decisions relating to the management of non-native species in postfire environments. Our approach provides a valuable tool for assisting decision makers to better manage non-native species, which can be readily adapted to target non-native species in other locations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Diversity and Distributions","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1366-9516.2004.00093.x","issn":"13669516","usgsCitation":"Underwood, E., Klinger, R., and Moore, P., 2004, Predicting patterns of non-native plant invasions in Yosemite National Park, California, USA: Diversity and Distributions, v. 10, no. 5-6, p. 447-459, https://doi.org/10.1111/j.1366-9516.2004.00093.x.","startPage":"447","endPage":"459","numberOfPages":"13","costCenters":[],"links":[{"id":489885,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1366-9516.2004.00093.x","text":"Publisher Index Page"},{"id":209082,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1366-9516.2004.00093.x"},{"id":235274,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"10","issue":"5-6","noUsgsAuthors":false,"publicationDate":"2004-09-06","publicationStatus":"PW","scienceBaseUri":"505a81c0e4b0c8380cd7b6eb","contributors":{"authors":[{"text":"Underwood, E.C.","contributorId":47134,"corporation":false,"usgs":true,"family":"Underwood","given":"E.C.","email":"","affiliations":[],"preferred":false,"id":411048,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Klinger, R.","contributorId":78493,"corporation":false,"usgs":true,"family":"Klinger","given":"R.","email":"","affiliations":[],"preferred":false,"id":411050,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Moore, P.E.","contributorId":57395,"corporation":false,"usgs":true,"family":"Moore","given":"P.E.","email":"","affiliations":[],"preferred":false,"id":411049,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The Institute was formed to develop cooperative approaches for invasive species science that meet the urgent needs of land managers and the public. Its mission is to work with others to coordinate data and research from many sources to predict and reduce the effects of harmful nonnative plants, animals, and diseases in natural areas and throughout the United States, with a strategic approach to information management, research, modeling, technical assistance, and outreach. The Institute research team will develop local-, regional-, and national- scale maps of invasive species and identify priority invasive species, vulnerable habitats, and pathways of invasion. County-level and point data on occurrence will be linked to plot-level and site-level information on species abundance and spread. FORT scientists and Institute partners are working to integrate remote sensing data and GIS-based predictive models to track the spread of invasive species across the country. This information will be linked to control and restoration efforts to evaluate their cost-effectiveness. Understanding both successes and failures will advance the science of invasive species containment and control as well as restoration of habitats and native biodiversity.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/fs20043145","usgsCitation":"Stohlgren, T., 2004, Fort Collins Science Center: Invasive Species Science: U.S. Geological Survey Fact Sheet 2004-3145, 2 p., https://doi.org/10.3133/fs20043145.","productDescription":"2 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":124811,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/fs_2004_3145.jpg"},{"id":320285,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/fs/2004/3145/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b23e4b07f02db6ae32a","contributors":{"authors":[{"text":"Stohlgren, Tom","contributorId":24037,"corporation":false,"usgs":true,"family":"Stohlgren","given":"Tom","email":"","affiliations":[],"preferred":false,"id":282925,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The investigation is a collaborated effort between the U.S. Geological Survey, Water Resources Discipline (WRD), and Geography (formerly National Mapping) Discipline, EROS Data Center.\r\n\r\nA water-quality monitoring program was initiated in 1973, when the EROS Data Center was constructed, and continues at the present time (2003). Under this program, water-quality samples were collected at various sites on the EROS Data Center's property and in the surrounding area. These sites include 4 wastewater-treatment lagoons, 1 site on EROS Lake located behind the EROS Data Center, 2 stream sites near the EROS Data Center, and 9 ground-water wells surrounding the EROS Data Center. Additionally, 3 sites on EROS Lake, 7 stream sites, and 9 ground-water sites are located within the study area and have been sampled during the period covered in the report. Some of these additional sites were part of the initial water-quality monitoring conducted during and immediately after the construction of the EROS Data Center. For other sites, some special sampling (depth-profile and bottom material) has occurred at times during the sampling history; however, these sites have little water-quality data and were not used for statistical or trend analysis.\r\n\r\nA trend-analysis program, Estimate TREND (ESTREND), was used to analyze for trends for one surface-water site, the Big Sioux River, which was the only site that had a substantial number of samples collected during an extensive period. The ESTREND trend-analysis program was used to analyze 16 constituents. Specific conductance and dissolved orthophosphate were the only constituents determined to have statistically significant trends. Results showed an increasing trend for specific conductance and a decreasing trend for dissolved orthophosphate.\r\n\r\nScatter plots with regression smoothing lines for selected constituents are presented for selected surface-water and ground-water sites. Regression analyses using a Lowess (Locally Weighted Scatterplot Smoothing) smoothing line for Split Rock Creek, EROS Lake, the lagoon sites, and the ground-water sites indicated variable results, with some constituents indicating an increasing or decreasing trend, some having varied results, and others indicating no change during the sampling period.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri034280","usgsCitation":"Neitzert, K.M., 2004, Water-quality characteristics and trends for selected sites in or near the Earth Resources Observation Systems (EROS) Data Center, South Dakota, 1973-2000: U.S. Geological Survey Water-Resources Investigations Report 2003-4280, v, 64 p., https://doi.org/10.3133/wri034280.","productDescription":"v, 64 p.","costCenters":[],"links":[{"id":420272,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_68227.htm","linkFileType":{"id":5,"text":"html"}},{"id":4681,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri034280/","linkFileType":{"id":5,"text":"html"}},{"id":177583,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"South Dakota","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -96.7667,\n              43.8333\n            ],\n            [\n              -96.7667,\n              43.6083\n            ],\n            [\n              -96.5333,\n              43.6083\n            ],\n            [\n              -96.5333,\n              43.8333\n            ],\n            [\n              -96.7667,\n              43.8333\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48cde4b07f02db544bc0","contributors":{"authors":[{"text":"Neitzert, Kathleen M. kmneitze@usgs.gov","contributorId":1833,"corporation":false,"usgs":true,"family":"Neitzert","given":"Kathleen","email":"kmneitze@usgs.gov","middleInitial":"M.","affiliations":[{"id":562,"text":"South Dakota Water Science Center","active":true,"usgs":true}],"preferred":true,"id":247664,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

To address this continuing trend in habitat changes and begin restoring historical patterns of disturbance, the Clearwater Basin Elk Habitat Initiative (CEI) proposes relatively extensive management actions in the Clearwater basin of north-central Idaho. We attempted to evaluate potential effects of such management actions on selected wildlife species using extant data sets and suggest ways to improve such projects with respect to a multispecies and adaptive management approach. Although there is increased interest in ecosystem management over large areas, the increased scale of analysis and implementation require a substantial increase in the level of species information beyond what currently exists. We conclude that baseline information required for an effective multispecies land-management policy in the Clearwater basin does not exist for many terrestrial wildlife species. To implement a true multispecies or ecosystem approach, wildlife and land managers should cooperate to increase existing population data and modeling efforts for wildlife species in the basin and develop a sustainable monitoring program to evaluate habitat management changes and their influence on wildlife populations within the context of adaptive management theory. Management actions to restore disturbance patterns should attempt spatial and temporal scales that are biologically relevant to the population ecology of species being affected.&nbsp;</p>","language":"English","publisher":"Oxford Academic","doi":"10.1093/wjaf/19.2.123","usgsCitation":"Scanvara, L., Servheen, G., Melquist, W., Davis, D., and Scott, J.M., 2004, Habitat restoration across large areas: Assessing wildlife responses in the Clearwater basin, Idaho: Western Journal of Applied Forestry, v. 19, no. 2, p. 123-132, https://doi.org/10.1093/wjaf/19.2.123.","productDescription":"10 p.","startPage":"123","endPage":"132","costCenters":[{"id":342,"text":"Idaho Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":478207,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1093/wjaf/19.2.123","text":"Publisher Index Page"},{"id":235244,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Idaho","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.09228515624999,\n              45.62940492064501\n            ],\n            [\n              -114.14794921875,\n              45.62940492064501\n            ],\n            [\n              -114.14794921875,\n              46.84516443029276\n            ],\n            [\n              -117.09228515624999,\n              46.84516443029276\n            ],\n            [\n              -117.09228515624999,\n              45.62940492064501\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"19","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2f1de4b0c8380cd5cad4","contributors":{"authors":[{"text":"Scanvara, L.K.","contributorId":54386,"corporation":false,"usgs":true,"family":"Scanvara","given":"L.K.","email":"","affiliations":[],"preferred":false,"id":411210,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Servheen, G.","contributorId":7479,"corporation":false,"usgs":true,"family":"Servheen","given":"G.","email":"","affiliations":[],"preferred":false,"id":411208,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Melquist, W.","contributorId":45093,"corporation":false,"usgs":true,"family":"Melquist","given":"W.","email":"","affiliations":[],"preferred":false,"id":411209,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Davis, D.","contributorId":85747,"corporation":false,"usgs":true,"family":"Davis","given":"D.","affiliations":[],"preferred":false,"id":411212,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Scott, J.

The elastic properties of gas-saturated sediments can be predicted by the classical Biot-Gassmann theory (BGT). However, parameters for the BGT such as the Biot coefficient or moduli of dry frame of unconsolidated and high porosity sediments are not readily available. Dependence of velocities on differential pressure or porosity for partially gas-saturated sediments is formulated using properties derived from velocities of water-saturated sediments. Laboratory samples for unconsolidated and consolidated sediments and well log data acquired for unconsolidated marine sediments agree well with the predictions. However, because the P-wave velocity depends highly on how the gas is saturated in the pore space such as uniform or patch, the amounts of gas estimated from the P-wave velocity contains high uncertainty. The modeled Vp/Vs ratio of partially gas-saturated sediment using the patch distribution is usually greater than 1.6, whereas the ratio modeled assuming a uniform distribution is about 1.6.

We provide a detailed analysis of sprint swimming ability of six migratory fish species (American shad (Alosa sapidissima), alewife (Alosa pseudoharengus), blueback herring (Alosa aestivalis), striped bass (Morone saxatilis), walleye (Stizostedion vitreum), and white sucker (Catostomus commersoni)) against controlled water velocities of 1.5-4.5 m??s-1 in a large, open-channel flume. Performance was strictly voluntary: no coercive incentives were used to motivate fish to sprint. We used these data to generate models of maximum distance traversed, taking into account effects of flow velocity, body length, and temperature. Although the maximum distance traversed decreased with increasing velocity, the magnitude of this effect varied among species. Other covariate effects were likewise variable, with divergent effects of temperature and nonuniform length effects. These effects do not account for all of the variability in performance, however, and behavioral traits may account for observed interspecific differences. We propose the models be used to develop criteria for fish passage structures, culverts, and breached dams.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Fisheries and Aquatic Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/F04-093","issn":"0706652X","usgsCitation":"Haro, A., Castro-Santos, T., Noreika, J., and Odeh, M., 2004, Swimming performance of upstream migrant fishes in open-channel flow: A new approach to predicting passage through velocity barriers: Canadian Journal of Fisheries and Aquatic Sciences, v. 61, no. 9, p. 1590-1601, https://doi.org/10.1139/F04-093.","startPage":"1590","endPage":"1601","numberOfPages":"12","costCenters":[],"links":[{"id":208407,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/F04-093"},{"id":234141,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"61","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba332e4b08c986b31fbf2","contributors":{"authors":[{"text":"Haro, A.","contributorId":6792,"corporation":false,"usgs":true,"family":"Haro","given":"A.","email":"","affiliations":[],"preferred":false,"id":411003,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Castro-Santos, T. 0000-0003-2575-9120","orcid":"https://orcid.org/0000-0003-2575-9120","contributorId":12416,"corporation":false,"usgs":true,"family":"Castro-Santos","given":"T.","affiliations":[],"preferred":false,"id":411004,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Noreika, J.","contributorId":51249,"corporation":false,"usgs":true,"family":"Noreika","given":"J.","email":"","affiliations":[],"preferred":false,"id":411005,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Odeh, M.","contributorId":95413,"corporation":false,"usgs":true,"family":"Odeh","given":"M.","affiliations":[],"preferred":false,"id":411006,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The scheme has been applied to remotely sensed imaging spectroscopy data acquired by the Airborne Visible and Infrared Imaging Spectrometer (AVIRIS) instrument. This approach was used to identify the minerals calcite, epidote, and chlorite in the upper Animas River watershed, Colorado. The study was motivated by the need to characterize the distribution of calcite in the watershed and assess its acid-neutralizing potential with regard to acidic mine drainage. Identification of these three minerals is difficult because their diagnostic spectral features are all centered at 2.3 ??m, and have similar shapes and widths. Previous studies overestimated calcite abundance as a result of these spectral overlaps. The use of a reference library containing synthetic mixtures of the three minerals in varying proportions was found to simplify the task of identifying these minerals when used in conjunction with a rule-based expert system. Some inaccuracies in the mineral distribution maps remain, however, due to the influence of a fourth spectral component, sericite, which exhibits spectral absorption features at 2.2 and 2.4 ??m that overlap the 2.3-??m absorption features of the other three minerals. Whereas the endmember minerals calcite, epidote, chlorite, and sericite can be identified by the method presented here, discrepancies occur in areas where all four occur together as intimate mixtures. It is expected that future work will be able to reduce these discrepancies by including reference mixtures containing sericite. ?? 2004 Elsevier Inc.

The large database on the geochemistry of this produced water shows salinities that vary widely from ~5,000 to &gt;350,000 mg/L TDS. Chloride, Na and Ca are generally the dominant ions, and concentrations of Fe, Mn, B, NH3 and dissolved organics, including, BTEX, phenols and poly aromatic hydrocarbons (PAHs) may be relatively high. Hazardous concentrations of NORMs, including Ra-226 and Rn-222 have been reported in produced water from several states.</p><p>Coal-bed methane (CBM) wells currently produce close to a billion barrels of water and deliver ~8% of total natural gas. The salinity of this produced water generally is lower than that of water from petroleum wells; salinity commonly is 1,000-20,000 mg/L, but ranges to150,000 mg/L TDS. Most CBM wells produce Na-HCO3-Cl type water that is low in trace metals and has no reported NORMs. This water commonly has no oil and grease and has relatively low DOC, but its organic composition has not been characterized in detail. The water is disposed of by injection into saline aquifers, through evaporation and/or percolation in disposal pits, road spreading, and surface discharge. Water that has an acceptable salinity and sodium absorption ratio (SAR) is considered acceptable for surface discharge and for injection into freshwater aquifers.</p><p>As an alternative to costly disposal, low salinity produced water is being considered for reclamation, especially in the arid western USA.

Important features shown on resultant GPR profiles include: (1) upward and lateral qualitative interpretative distribution of porosity and hydraulic conductivity; (2) paleotopographic relief on karstic subaerial exposure surfaces; and (3) vertical stacking of chronostratigraphic high-frequency cycles (HFCs). These characteristics were verified by comparison to rock properties observed and measured in core samples, and identified in digital optical borehole images. Results demonstrate that an empirical relation exists between measured whole-core porosity and hydraulic conductivity, observed porosity on digital optical borehole images, formation conductivity, and GPR reflection amplitudes-as porosity and hydraulic conductivity determined from core and borehole images increases, formation conductivity increases, and GPR reflection amplitude decreases. This relation allows for qualitative interpretation of the vertical and lateral distribution of porosity and hydraulic conductivity within HFCs. Two subtidal HFCs in the uppermost Biscayne aquifer have significantly unique populations of whole-core porosity values and vertical hydraulic conductivity values. Porosity measurements from one cycle has a median value about two to three times greater than the values from the other HFC, and median values of vertical hydraulic-conductivity about three orders of magnitude higher than the other HFC. The HFC with the higher porosity and hydraulic conductivity values is shown as a discrete package of relatively low-amplitude reflections, whereas the HFC characterized by lower porosity and hydraulic-conductivity measurements is expressed by higher amplitude reflections. Porosity and hydraulic-conductivity values measured from whole-core samples, and vuggy porosity identified on digital borehole images from shallowing-upward, peritidal HFCs show that the highest porosity occurs at the base of the cycles, moderate porosity at the middle of the cycles, and lowest porosity occurs at the top of cycles. Hydraulic conductivity is also highest at the base of the peritidal cycles and lowest in the middle to upper parts of cycles. This change in porosity and hydraulic conductivity from bottom to top is visible as an upward variation in reflection amplitude on GPR profiles-lowest amplitudes at the base and highest at the cycle tops. This study demonstrates that GPR can be used to show the qualitative distribution of porosity and hydraulic conductivity within a cycle-stratigraphic framework composed of carbonate HFCs. The distribution of porosity and hydraulic conductivity within HFCs is related to depositional textures. The upward and lateral patterns of the rock facies within the HFCs can be translated to geophysical-log properties and radar facies configurations that could aid in interpretation and prediction of ground-water flow through a carbonate aquifer. ?? 2003 Elsevier B.V.

Complex systems modeling is proposed as a general framework in which to build models that can evaluate outcomes. Three frequently used methods of mineral resource appraisal (subjective probabilistic estimates, weights of evidence modeling, and fuzzy logic modeling) are discussed to obtain insight into methods of incorporating complexity into mineral resource appraisal models. Fuzzy logic and weights of evidence are most easily utilized in complex systems models. A fundamental product of new appraisals is the production of reusable, accessible databases and methodologies so that appraisals can easily be repeated with new or refined data. The data are representations of complex systems and must be so regarded if all of their information content is to be utilized. The proposed generalized model framework is applicable to mineral assessment and other geoscience problems. We begin with a (fuzzy) cognitive map using (+1,0,-1) values for the links and evaluate the map for various scenarios to obtain a ranking of the importance of various links. Fieldwork and modeling studies identify important links and help identify unanticipated links. Next, the links are given membership functions in accordance with the data. Finally, processes are associated with the links; ideally, the controlling physical and chemical events and equations are found for each link. After calibration and testing, this complex systems model is used for predictions under various scenarios.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00267-003-2835-7","issn":"0364152X","usgsCitation":"Gettings, M.E., Bultman, M., and Fisher, F., 2004, A Complex Systems Model Approach to Quantified Mineral Resource Appraisal: Environmental Management, v. 33, no. 1, p. 87-98, https://doi.org/10.1007/s00267-003-2835-7.","startPage":"87","endPage":"98","numberOfPages":"12","costCenters":[],"links":[{"id":238177,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211031,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00267-003-2835-7"}],"volume":"33","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e2d3e4b0c8380cd45c88","contributors":{"authors":[{"text":"Gettings, M.

These data indicate that basalt clasts and vitroclasts in a given outburst‐flood deposit came from a common source, a lava dam. With these data, it is possible to distinguish individual dam‐flood events and improve our understanding of the interrelations of volcanism and river processes. At least five lava dams on the Colorado River failed catastrophically between 100 and 525 ka; subsequent outburst floods emplaced basalt‐rich deposits preserved on benches as high as 200 m above the current river and up to 53 km downstream of dam sites. Chemical data also distinguishes individual lava flows that were collectively mapped in the past as large long‐lasting dam complexes. These chemical data, in combination with age constraints, increase our ability to correlate lava dams and outburst‐flood deposits and increase our understanding of the longevity of lava dams. Bases of correlated lava dams and flood deposits approximate the elevation of the ancestral river during each flood event.

In the southeastern coastal plain of Virginia, high-sensitivity borehole pipe extensometers were used to measure 24.2 mm of total compaction at Franklin from 1979 through 1995 (1.5 mm/year) and 50.2 mm of total compaction at Suffolk from 1982 through 1995 (3.7 mm/year). Analysis of the extensometer data reveals that the small rates of aquifer-system compaction appear to be correlated with withdrawals of water from confined aquifers. One-dimensional vertical compaction modeling indicates measured compaction is the result of nonrecoverable hydrodynamic consolidation of the fine-grained confining units and interbeds, as well as recoverable compaction and expansion of coarse-grained aquifer units. The calibrated modeling results indicate that nonrecoverable specific storage values decrease with depth and range from 1.5 x 10-5/m for aquifer units to 1.5 x 10-4/m for confining units and interbeds. The aquifer and Potomac system recoverable specific storage values were all estimated to be 4.5 x 10-6/m, while the confining units and interbeds had values of 6.0 x 10-6/m. The calibrated vertical hydraulic conductivity values of the confining units and interbeds ranged from 6.6 x 10-4 m/year to 2.0 x 10-3 m/year. These parameter values will be useful in future management and modeling of ground water in the Virginia Coastal Plain.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ground Water","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1745-6584.2004.tb02449.x","issn":"0017467X","usgsCitation":"Pope, J., and Burbey, T., 2004, Multiple-Aquifer Characterization from Single Borehole Extensometer Records: Ground Water, v. 42, no. 1, p. 45-58, https://doi.org/10.1111/j.1745-6584.2004.tb02449.x.","startPage":"45","endPage":"58","numberOfPages":"14","costCenters":[],"links":[{"id":238349,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211143,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6584.2004.tb02449.x"}],"volume":"42","issue":"1","noUsgsAuthors":false,"publicationDate":"2005-12-13","publicationStatus":"PW","scienceBaseUri":"505a6086e4b0c8380cd714fd","contributors":{"authors":[{"text":"Pope, J.P.","contributorId":25352,"corporation":false,"usgs":true,"family":"Pope","given":"J.P.","email":"","affiliations":[],"preferred":false,"id":414806,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Burbey, T.

Such studies are essential for assessing the influence of sorption processes on the transport of Hg in contaminated natural systems. Macroscopic uptake of Hg(II) on goethite (??-FeOOH), ??-alumina (??-Al2O3), and bayerite (??-Al(OH)3) as a function of pH has been combined with Hg L III-edge EXAFS spectroscopy, FTIR spectroscopy, and bond valence analysis of possible sorption products to provide this type of information. Macroscopic uptake measurements show that Hg(II) sorbs strongly to fine-grained powders of synthetic goethite (Hg sorption density ??=0.39-0.42 ??mol/m2) and bayerite (??=0.39-0.44 ??mol/m2), while sorbing more weakly to ??-alumina (??=0.04-0.13 ??mol/m 2). EXAFS spectroscopy on the sorption samples shows that the dominant mode of Hg sorption on these phases is as monodentate and bidentate inner-sphere complexes. The mode of Hg(II) sorption to goethite was similar over the pH range 4.3-7.4, as were those of Hg(II) sorption to bayerite over the pH range 5.1-7.9. Conversion of the ??-Al2O3 sorbent to a bayerite-like phase in addition to the apparent reduction of Hg(II) to Hg(I), possibly by photoreduction during EXAFS data collection, resulted in enhanced Hg uptake from pH 5.2-7.8 and changes in the modes of sorption that correlate with the formation of the bayerite-like phase. Bond valence calculations are consistent with the sorption modes proposed from EXAFS analysis. EXAFS analysis of Hg(II) sorption products on a natural Fe oxyhydroxide precipitate and Al/Si-bearing flocculent material showed sorption products and modes of surface attachment similar to those for the model substrates, indicating that the model substrates are useful surrogates for the natural sediments. ?? 2003 Elsevier Inc.

Although the regional flow system can be characterized generally as east to northeasterly from the Rocky Mountains towards the Missouri River, locally the flow systems are hydrologically complex. This study uses Sr isotopic data from groundwater and leached aquifer samples to document the complex subsystems within the Dakota aquifer in Nebraska and Kansas. The interaction of groundwater with the geologic material through which it flows has created spatial patterns in the isotopic measurements that are related to: long-term water-rock interaction, during which varying degrees of isotopic equilibrium between water and rock has been achieved; and the alteration of NaCl fluids by water-rock interaction. Specifically, Sr isotopic data distinguish brines from Kansas and western Nebraska from those in eastern Nebraska: the former are interpreted to reflect interaction with Permian rocks, whereas the latter record interaction with Pennsylvanian rocks. The Sr isotopic composition of groundwater from other parts of Nebraska and Kansas are a function of the dynamic interaction between groundwater and unlithified sediments (e.g., glacial till and loess), followed by interaction with oxidized and unoxidized sediments within the Dakota Formation. This study illustrates the power of combining Sr chemistry with more conventional geochemical data to obtain a more complete understanding of groundwater flow systems within regional aquifer systems where extensive monitoring networks do not exist. ?? 2003 Elsevier Ltd.

This paper presents results of an on-going sediment and geomorphic study in Judy's Branch. The average suspended-sediment yield from two upland sub-basins (drainage area equals 0.23 and 0.40 miles2) is 851 tons/mile2-year between October 2000 and September 2003. The suspended-sediment yield at the Route 157 gage (2,188 tons/mile 2-year) (near outlet of the watershed; drainage area = 8.33 miles2) is approximately 1300 tons/mile2-year greater than the average of the upland gages for the same time period. This result is unexpected in that generally the suspended-sediment yield decreases as the watershed area increases because of sediment being stored in the channel and floodplain. The difference indicates a possible increase in yield from a source, such as streambank erosion, and supports the theory that land-use changes increase streamflows that may result in higher rates of streambank erosion. The best estimate of sediment yield from streambank erosion is 1,009 tons/mile 2-year at Route 157. This value is obtained utilizing both bank-rod data and resurveyed cross-section data.","largerWorkTitle":"Proceedings of the 2004 World Water and Environmetal Resources Congress: Critical Transitions in Water and Environmetal Resources Management","conferenceTitle":"2004 World Water and Environmental Resources Congress: Critical Transitions in Water and Environmental Resources Management","conferenceDate":"27 June 2004 through 1 July 2004","conferenceLocation":"Salt Lake City, UT","language":"English","isbn":"0784407371","usgsCitation":"Straub, T.D., 2004, St. Louis Metro East region sediment and geomorphic study, <i>in</i> Proceedings of the 2004 World Water and Environmetal Resources Congress: Critical Transitions in Water and Environmetal Resources Management, Salt Lake City, UT, 27 June 2004 through 1 July 2004, p. 4463-4474.","startPage":"4463","endPage":"4474","numberOfPages":"12","costCenters":[],"links":[{"id":233969,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9645e4b08c986b31b3e9","contributors":{"editors":[{"text":"Sehlke G.Hayes D.F.Stevens D.K.","contributorId":128420,"corporation":true,"usgs":false,"organization":"Sehlke G.Hayes D.F.Stevens D.K.","id":536597,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Straub, T.

Using intensity scales for wind damages, an equivalent water-damage flow intensity scale has been developed that ranges from 1 (minimal effects) to 10 (major damages to most structures). This flow intensity scale, FIS, is portrayed on a map as color-coded areas of increasing flow intensity. This should prove to be a valuable tool to assess relative risk to people and property in known flood-hazard areas.","largerWorkTitle":"Proceedings of the 2004 World Water and Environmetal Resources Congress: Critical Transitions in Water and Environmetal Resources Management","conferenceTitle":"2004 World Water and Environmental Resources Congress: Critical Transitions in Water and Environmental Resources Management","conferenceDate":"27 June 2004 through 1 July 2004","conferenceLocation":"Salt Lake City, UT","language":"English","isbn":"0784407371","usgsCitation":"Fulford, J., 2004, An intensity scale for riverine flooding, <i>in</i> Proceedings of the 2004 World Water and Environmetal Resources Congress: Critical Transitions in Water and Environmetal Resources Management, Salt Lake City, UT, 27 June 2004 through 1 July 2004, p. 2008-2016.","startPage":"2008","endPage":"2016","numberOfPages":"9","costCenters":[],"links":[{"id":234437,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ea82e4b0c8380cd488f2","contributors":{"editors":[{"text":"Sehlke G.Hayes D.F.Stevens D.K.","contributorId":128420,"corporation":true,"usgs":false,"organization":"Sehlke G.Hayes D.F.Stevens D.K.","id":536596,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Fulford, J.M.","contributorId":27473,"corporation":false,"usgs":true,"family":"Fulford","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":409085,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
