It hypothesizes that sea-level changes interact with subtle variations in paleotopography to influence the heterogeneity of potential reservoir systems in mixed carbonate-silidclastic systems, commonly produdng build-and-fill sequences. For this analysis, ten lithofacies were identified: (1) phylloid algal boundstone-packstone, (2) skeletal wackestone-packstone, (3) peloidal, skeletal packstone, (4) sandy, skeletal grainstone-packstone, (5) oolite grainstone-packstone, (6) Osagia-brachiopod packstone, (7) fossiliferous siltstone, (8) lenticular bedded-laminated siltstone and fine sandstone, (9) organic-rich mudstone and coal, and (10) massive mudstone. Each facies can be related to depositional environment and base-level changes to develop a sequence stratigraphy consisting of three sequence boundaries and two flooding surfaces. Within this framework, eighteen localities are used to develop a threedimensional framework of the stratigraphy and paleotopography. The studied strata illustrate the model of \"build-and-fill\". In this example, phylloid algal mounds produce initial relief, and many of the later carbonate and silidclastic deposits are focused into subtle paleotopographic lows, responding to factors related to energy, source, and accommodation, eventually filling the paleotopography. After initial buildup of the phylloid algal mounds, marine and nonmarine siliciclastics, with characteristics of both deltaic lobes and valley fills, were focused into low areas between mounds. After a sea-level rise, oolitic carbonates formed on highs and phylloid algal facies accumulated in lows. A shift in the source direction of siliciclastics resulted from flooding or filling of preexisting paleotopographic lows. Fine-grained silidclastics were concentrated in paleotopographic low areas and resulted in clay-rich phylloid algal carbonates that would have made poor reservoirs. In areas more distant from silidclastic influx, phylloid algal facies with better reservoir potential formed in topographic lows. After another relative fall in sea level, marine carbonates and silidclastics were concentrated in paleotopographic low areas. After the next relative rise in sea level, there is little thickness or fades variation in phylloid algal limestone throughout the study area because: (1) substrate paleotopography had been subdued by filling, and (2) no silidclastics were deposited in the area. Widespread subaerial exposure and erosion during a final relative fall in sea level resulted in redevelopment of variable paleotopography. Build-and-fill sequences, such as these, are well known in other surface and subsurface examples. Initial relief is built by folding or faulting, differential compaction, erosion, or deposition of relief-building facies, such as phylloid algal and carbonate grainstone reservoir fades, or silidclastic wedges. Relief is filled through deposition of reservoir-fades siliciclastics, phylloid algal fades, and grainy carbonates, as well as nonreservoir facies, resulting in complex heterogeneity.","language":"English","publisher":"Society for Sedimentary Geology","doi":"10.2110/pec.03.78.0097","usgsCitation":"McKirahan, J., Goldstein, R., and Franseen, E.K., 2005, Build-and-fill sequences: How subtle paleotopography affects 3-D heterogeneity of potential reservoir facies: AAPG Memoir, v. 79, p. 97-116, https://doi.org/10.2110/pec.03.78.0097.","productDescription":"20 p.","startPage":"97","endPage":"116","numberOfPages":"20","costCenters":[],"links":[{"id":238521,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"79","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f2a6e4b0c8380cd4b28e","contributors":{"authors":[{"text":"McKirahan, J.R.","contributorId":68103,"corporation":false,"usgs":true,"family":"McKirahan","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":413564,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Goldstein, R.H.","contributorId":18908,"corporation":false,"usgs":true,"family":"Goldstein","given":"R.H.","affiliations":[],"preferred":false,"id":413562,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Franseen, E.

The approach converts measurements of stage into discharge using a fluid mechanically based model. The model does not use empirical roughness coefficients, such as Manning coefficients, but rather determines channel roughness from field measurements of the (1) channel geometry, (2) the physical roughness of the bed, banks, and floodplain, and (3) the vegetation density on the banks and floodplain. These measurements are used to calculate explicitly the drag on the small-scale topographic features on the boundary, the drag on the stems and branches of woody vegetation, and the friction on the bed, banks, and floodplain. The theoretical rating curves produced by the model for two study reaches, which are near U.S. Geological Survey (USGS) streamflow-gauging stations, are in good agreement with direct measurements of discharge made by the USGS. Our method has the potential of providing accurate estimates of stream flows less expensively than conventional gauging methods. In addition, the method can be used to obtain more accurate discharge estimates than conventional indirect methods for determining discharge, which are based on estimates of Manning's coefficient.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research F: Earth Surface","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1029/2004JF000250","issn":"01480227","usgsCitation":"Kean, J., and Smith, J., 2005, Generation and verification of theoretical rating curves in the Whitewater River basin, Kansas: Journal of Geophysical Research F: Earth Surface, v. 110, no. 4, https://doi.org/10.1029/2004JF000250.","costCenters":[],"links":[{"id":477939,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2004jf000250","text":"Publisher Index Page"},{"id":211186,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2004JF000250"},{"id":238409,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"110","issue":"4","noUsgsAuthors":false,"publicationDate":"2005-11-18","publicationStatus":"PW","scienceBaseUri":"505a1550e4b0c8380cd54d57","contributors":{"authors":[{"text":"Kean, J.

After 100 years, the 250 mg/L chloride isochlor moved inland by about 40 m, and required an additional 8 years for the system to reach equilibrium. For the next simulation, sea-level rise was specified at 4.8 mm/yr, which is the central value of the IPCC estimate. For this moderate rate of sea-level rise, the 250 mg/L isochlor moved inland by about 740 m after 100 years, and required an additional 10 years for the system to reach equilibrium. For the fastest rate of sea level rise estimated by IPCC (8.8 mm/yr), the 250 mg/L isochlor moved inland by about 1800 m after 100 years, and required more than 50 years to reach equilibrium.

Determining the distribution of seepage loss along mountain front streams is important when assessing groundwater resources of the region. Seepage loss along a mountain front stream in northern Nevada was evaluated using a one‐dimensional unsteady streamflow model. Seepage loss was incorporated into the spatial derivatives of the streamflow equations. Because seepage loss from streams is dependent on stream depth, wetted perimeter, and streambed properties, a two‐dimensional variably saturated flow model was used to develop a series of relations between seepage loss and stream depth for each reach. This method works when streams are separated from groundwater by variably saturated sediment. Two periods of intermittent flow were simulated to evaluate the modeling approach. The model reproduced measured flow and seepage losses along the channel. Seepage loss in the spring of 2000 was limited to the upper reaches on the alluvial plain and totaled 196,000 m</span><sup>3</sup><span>, whereas 64% of the seepage loss in the spring of 2004 occurred at the base of the alluvial plain and totaled 273,000 m</span><sup>3</sup><span>. A greater seepage loss at the base of the piedmont alluvial plain is attributed to increased streambed hydraulic conductivity caused by less armoring of the channel.

In the case of the invasive Argentine ant (Linepithema humile), most prior studies have investigated this species' limitations in hot and dry climates. However, spatial and temporal patterns of spread involving two ant populations over the course of 30 years at a high elevation site in Hawaii suggest that cold and wet conditions have influenced both the ant's distribution and its rate of invasion. In Haleakala National Park on Maui, we found that a population invading at lower elevation is limited by increasing rainfall and presumably by associated decreasing temperatures. A second, higher elevation population has spread outward in all directions, but rates of spread in different directions appear to have been strongly influenced by differences in elevation and temperature. Patterns of foraging activity were strongly tied to soil temperatures, supporting the hypothesis that variation in temperature can influence rates of spread. Based on past patterns of spread, we predicted a total potential range that covers nearly 50% of the park and 75% of the park's subalpine habitats. We compared this rough estimate with point predictions derived from a degree-day model for Argentine ant colony reproduction, and found that the two independent predictions match closely when soil temperatures are used in the model. The cold, wet conditions that have influenced Argentine ant invasion at this site are likely to be influential at other locations in this species' current and future worldwide distribution.&nbsp;</p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1366-9516.2005.00151.x","issn":"13669516","usgsCitation":"Krushelnycky, P., Joe, S., Medeiros, A., Daehler, C., and Loope, L., 2005, The role of abiotic conditions in shaping the long-term patterns of a high-elevation Argentine ant invasion: Diversity and Distributions, v. 11, no. 4, p. 319-331, https://doi.org/10.1111/j.1366-9516.2005.00151.x.","productDescription":"13 p.","startPage":"319","endPage":"331","numberOfPages":"13","costCenters":[],"links":[{"id":240668,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213081,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1366-9516.2005.00151.x"}],"country":"United States","state":"Hawaii","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -156.26266479492188,\n              20.60322165468188\n            ],\n            [\n              -156.03744506835938,\n              20.60322165468188\n            ],\n            [\n              -155.9564208984375,\n              20.69317690866736\n            ],\n            [\n              -155.95367431640625,\n              20.817741019786485\n            ],\n            [\n              -156.1871337890625,\n              20.9011542773029\n            ],\n            [\n              -156.26266479492188,\n              20.78693059257028\n            ],\n            [\n              -156.26266479492188,\n              20.60322165468188\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"11","issue":"4","noUsgsAuthors":false,"publicationDate":"2005-07-04","publicationStatus":"PW","scienceBaseUri":"505baf4de4b08c986b3246c7","contributors":{"authors":[{"text":"Krushelnycky, P.D.","contributorId":27664,"corporation":false,"usgs":true,"family":"Krushelnycky","given":"P.D.","affiliations":[],"preferred":false,"id":423648,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Joe, S.M.","contributorId":97775,"corporation":false,"usgs":true,"family":"Joe","given":"S.M.","affiliations":[],"preferred":false,"id":423650,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Medeiros, A.C.","contributorId":19703,"corporation":false,"usgs":true,"family":"Medeiros","given":"A.C.","email":"","affiliations":[],"preferred":false,"id":423647,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Daehler, C.C.","contributorId":100139,"corporation":false,"usgs":true,"family":"Daehler","given":"C.C.","email":"","affiliations":[],"preferred":false,"id":423651,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Loope, L.L.","contributorId":43126,"corporation":false,"usgs":true,"family":"Loope","given":"L.L.","email":"","affiliations":[],"preferred":false,"id":423649,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Holocene lagoonal reefs were established between 8700 and 7800 years B.P. on 130,000-200,000 year-old reef platforms that are presently 7 to 22 m below the floor of the lagoons. Comparison of radiocarbon ages of the deepest corals to published sea-level curves indicate that Holocene reefs colonized these substrates rapidly (<???500 years) after lagoon flooding, in water depths of less than 8 m. Subsequently, reef growth lagged behind sea-level rise until the outer reef rims reached sea level between 5000 and 4000 years B.P. Average vertical sediment accretion rates for the Holocene in the lagoons varied by location (83 ?? 2 to 278 ?? 8 cm/ka) and decreased through the Holocene in six of seven drill holes as the lagoons shallowed and became enclosed by the outer reef. A sample from an emergent (<0.5 m above present mean tide) reef on Rakahanga is 4610 ?? 100 years old, which may indicate a higher middle Holocene relative sea level on Rakahanga. Coral growth in Rakahanga lagoon ceased less than 2000 years ago, but was prolific in the early to middle Holocene. The timing and pattern of Holocene reef development exhibited in the Cook Islands is consistent with other oceanic islands. An assessment of the response of reef development to sea-level change during the Holocene provides a baseline to predict how future sea-level changes may affect the morphology of modern reefs.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Coastal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"07490208","usgsCitation":"Gray, S., and Hein, J., 2005, Lagoonal reef accretion and holocene sea-level history from three atolls in the Cook Islands, Central South Pacific: Journal of Coastal Research, v. 21, no.

To model debris flows in the Yosemite Valley, we selected six streams with evidence of historical debris flows; three of the debris flow deposits have single channels, and the other three split their pattern in the fan area into two or more channels. From field observations all of the debris flows involved coarse material, with only very small clay content. We applied the one dimensional DAN (Dynamic ANalysis) model (Hungr, 1995) and the two-dimensional FLO2D model (O'Brien et al., 1993) to predict and compare the runout distance and the velocity of the debris flows observed in the study area. As a first step, we calibrated the parameters for the two softwares through the back analysis of three debris- flows channels using a trial-and-error procedure starting with values suggested in the literature. In the second step we applied the selected values to the other channels, in order to evaluate their predictive capabilities. After parameter calibration using three debris flows we obtained results similar to field observations We also obtained a good agreement between the two models for velocities.

The extent, degree, and permanency of these modifications compromise the use of traditional reference-based study designs to evaluate the level of lotic impairment and establish restoration goals. Directly relating biological responses to the combined effects of urbanization is further complicated by the nonlinear response often observed in common metrics (e.g., Ephemeroptera, Plecoptera, and Trichoptera [EPT] species richness) to measures of human influence (e.g., percentage urban land cover). A characteristic polygonal biological response often arises from the presence of a generalized limiting factor (i.e., urban land use) plus the influence of multiple additional stressors that are nonuniformly distributed throughout the urban environment. Benthic macroinvertebrates, on-site physical habitat and chemistry, and geographical information systems-derived land cover data for 85 sites were collected within the 1,600-km2 Santa Clara Valley (SCV), California urban area. A biological indicator value was derived from EPT richness and percentage EPT. Partitioned regression was used to define reference conditions and estimate the degree of site impairment. We propose that an upper-boundary condition (factor-ceiling) modeled by partitioned regression using ordinary least squares represents an attainable upper limit for biological condition in the SCV area. Indicator values greater than the factor-ceiling, which is monotonically related to existing land use, are considered representative of reference conditions under the current habitat conditions imposed by existing land cover and land use.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":" Effects of Urbanization on Stream Ecosystems","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"American Fisheries Society","issn":"08922284","usgsCitation":"Carter, J., and Fend, S., 2005, Setting limits: The development and use of factor-ceiling distributions for an urban assessment using macroinvertebrates, chap. <i>of</i>  Effects of Urbanization on Stream Ecosystems: American Fisheries Society Symposium, v. 47, p. 179-191.","productDescription":"13 p.","startPage":"179","endPage":"191","numberOfPages":"13","costCenters":[],"links":[{"id":238293,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":358056,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://fisheries.org/bookstore/all-titles/afs-symposia/x54047xm/"}],"volume":"47","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8d70e4b08c986b3183e7","contributors":{"authors":[{"text":"Carter, J.L.","contributorId":26030,"corporation":false,"usgs":true,"family":"Carter","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":413525,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fend, S.V. 0000-0002-4638-6602","orcid":"https://orcid.org/0000-0002-4638-6602","contributorId":99702,"corporation":false,"usgs":true,"family":"Fend","given":"S.V.","affiliations":[],"preferred":false,"id":413526,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Urban intensity was based on a multi-metric index (urban intensity index or UII) that included measures of land cover, socioeconomic organization, and urban infrastructure. Twenty-eight physical variables describing channel morphology, hydraulic properties, and streambed conditions were examined. None of the habitat variables was significantly correlated with urbanization intensity in all three study areas. Urbanization effects on stream habitat were less apparent for streams in SLC and BIR, owing to the strong influence of basin slope (SLC) and drought conditions (BIR) on local flow regimes. Streamflow in the BOS study area was not unduly influenced by similar conditions of climate and physiography, and habitat conditions in these streams were more responsive to urbanization. Urbanization in BOS contributed to higher discharge, channel deepening, and increased loading of fine-grained particles to stream channels. The modifying influence of basin slope and climate on hydrology of streams in SLC and BIR limited our ability to effectively compare habitat responses among different urban settings and identify common responses that might be of interest to restoration or water management programs. Successful application of land-use models such as the UII to compare urbanization effects on stream habitat in different environmental settings must account for inherent differences in natural and anthropogenic factors affecting stream hydrology and geomorphology. The challenge to future management of urban development is to further quantify these differences by building upon existing models, and ultimately develop a broader understanding of urbanization effects on aquatic ecosystems.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Effects of Urbanization on Stream Ecosystems","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"American Fisheries Society","issn":"08922284","usgsCitation":"Short, T., Giddings, E., Zappia, H., and Coles, J., 2005, Urbanization effects on stream habitat characteristics in Boston, Massachusetts; Birmingham, Alabama; and Salt Lake City, Utah, chap. <i>of</i> Effects of Urbanization on Stream Ecosystems: American Fisheries Society Symposium, v. 47, p. 317-332.","productDescription":"16 p.","startPage":"317","endPage":"332","numberOfPages":"16","costCenters":[],"links":[{"id":238259,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":358058,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://fisheries.org/bookstore/all-titles/afs-symposia/x54047xm/"}],"volume":"47","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbe44e4b08c986b3294c0","contributors":{"authors":[{"text":"Short, T.M.","contributorId":50626,"corporation":false,"usgs":true,"family":"Short","given":"T.M.","email":"","affiliations":[],"preferred":false,"id":413514,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Giddings, E.M.P.","contributorId":36348,"corporation":false,"usgs":true,"family":"Giddings","given":"E.M.P.","email":"","affiliations":[],"preferred":false,"id":413513,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zappia, H.","contributorId":94474,"corporation":false,"usgs":true,"family":"Zappia","given":"H.","affiliations":[],"preferred":false,"id":413516,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Coles, J.F.","contributorId":80257,"corporation":false,"usgs":true,"family":"Coles","given":"J.F.","affiliations":[],"preferred":false,"id":413515,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

They developed as mud mounds, biodetrital calcisiltite mounds, and bryozoan frame thickets (fenestrate-frame coquina or rudstone) during the Kinderhookian and early Meramecian (Tournaisian and early Visean), and as microbial mud mounds, microbial- serpulidbryozoanboundstones, and solenoporoid (red algal) boundstones during the Chesterian (late Visean and Serpukhovian). True Waulsortian mounds did not develop in the Illinois Basin, but echinoderm (primarily crinoids)-bryozoan carbonate banks and bryozoan frame thickets generally occupied the same niche during the Kinderhookian-early Meramecian. Nutrient availability and the resulting increase in the productivity of echinoderms and bryozoans were apparently detrimental to Waulsortian mound development. Deposition of crinoidal-bryozoan carbonates during the Kinderhookian-Osagean initially occurred on a ramp setting that later evolved into a platform with a relatively steep margin through sediment aggradation and progradation. By mid-Osagean-early Meramecian, two such platforms, namely the Burlington Shelf and the Ullin Platform, developed adjacent to a deep, initially starved basin. Sedimentologic and petrographic characteristics of the Kinderhookian-earliest Meramecian carbonates resemble the modern cool-water Heterozoan Association. This is in contrast with post-earliest Meramecian carbonates, which are typically oolitic and peloidal with common peri tidal facies. The post-earliest Meramecian carbonates, therefore, resemble those of the warm-water Photozoan Association. The prevalence of Heterozoan carbonates in the Illinois Basin correlates with a rapid increase in the rate of subsidence and a major second-order eustatic sea-level rise that resulted in deep-water starved basins at this time. In the starved Illinois Basin, deposition was initially limited to a thin phosphatic shale that was followed later by deposition of up to 200 m of siliceous, spiculitic, and radiolarianbearing limestone. The starved basin was connected to the deep open ocean through a bathymetric depression, which was centered over the failed late Precambrian-Early Cambrian Reelfoot Rift, which extended from the deep-water Ouachita Trough in central Arkansas to southern Illinois, approximately parallel to the trend of the modern Mississippi River. We believe that upwelling of cool, nutrient- and silica-rich deep oceanic water, which entered the basin through this bathymetric depression, resulted in proliferation of pelmatozoans and bryozoans. The subsequent change from cool-water-like carbonates to warm-water-like carbonates appears to be related to decreased subsidence and gradual shallowing of the basin.","language":"English","publisher":"Society for Sedimentary Geology","doi":"10.2110/pec.03.78.0069","usgsCitation":"Lasemi, Z., Norby, R.D., Utgaard, J.E., Ferry, W.R., Cuffey, R.J., and Dever, G.R., 2005, Mississippian carbonate buildups and development of cool-waterlike carbonate platforms in the Illinois Basin, Midcontinent U.S.A.: AAPG Memoir, v. 78, p. 69-95, https://doi.org/10.2110/pec.03.78.0069.","productDescription":"27 p.","startPage":"69","endPage":"95","numberOfPages":"27","costCenters":[],"links":[{"id":238156,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Illinois","otherGeospatial":"Illinois basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -87.8466796875,\n              40.97989806962013\n            ],\n            [\n              -90.3076171875,\n              41.705728515237524\n            ],\n            [\n              -91.4501953125,\n              40.212440718286466\n            ],\n            [\n              -89.6044921875,\n              37.92686760148135\n            ],\n            [\n              -88.505859375,\n              37.50972584293751\n            ],\n            [\n              -87.4951171875,\n              39.13006024213511\n            ],\n            [\n              -87.8466796875,\n              40.97989806962013\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"78","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5b63e4b0c8380cd6f529","contributors":{"authors":[{"text":"Lasemi, Z.","contributorId":17795,"corporation":false,"usgs":true,"family":"Lasemi","given":"Z.","email":"","affiliations":[],"preferred":false,"id":413475,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Norby, R.

We describe changes in geometry, velocity, and strain rate and present a top-down force balance analysis performed over the lower reach of Columbia Glacier. Our analysis uses new measurements and estimates of basal topography and photogrammetric surface velocity measurements made between 1977 and 2001, while assuming depth-independent strain. Sensitivity tests show that the method is robust and insensitive to small changes in the calculation parameters. Spatial distributions of ice speed show little correspondence with driving stress. Instead, spatial patterns of ice speed exhibit a nonlinear correspondence with basal drag. Primary resistance to flow comes from basal drag, but lateral drag becomes increasingly more important throughout the retreat, which may account for observed increases in speed. Maximum basal drag is always located in a prominent constriction located ~12 km upstream from the preretreat terminus. Once the terminus retreated into deep water off the terminal moraine marking the modern maximum extent, the upstream location of this maximum basal drag helped to promote thinning and decrease effective pressure in the lower region by limiting replenishing ice flow from upstream. An increase in both ice velocity and calving resulted, initiating what appears to be an irreversible retreat.

This results in inaccurate estimates of summary statistics and regression coefficients, distorts evaluations of whether data follow a normal distribution, and introduces inaccuracies into risk assessments and models. Insider censoring occurs when data measured as below the detection limit (<DL) are reported as less than the higher quantitation limit (<QL), whereas values between the DL and QL are reported as individual numbers. Three unbiased alternatives to insider censoring are presented so that laboratories and their data users can recognize, and remedy, this problem.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Human and Ecological Risk Assessment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1080/10807030500278586","issn":"10807039","usgsCitation":"Helsel, D., 2005, Insider censoring: Distortion of data with nondetects: Human and Ecological Risk Assessment, v. 11, no. 6, p. 1127-1137, https://doi.org/10.1080/10807030500278586.","startPage":"1127","endPage":"1137","numberOfPages":"11","costCenters":[],"links":[{"id":210992,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/10807030500278586"},{"id":238120,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"11","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3c1ee4b0c8380cd62a9d","contributors":{"authors":[{"text":"Helsel, D.R.","contributorId":57448,"corporation":false,"usgs":false,"family":"Helsel","given":"D.R.","email":"","affiliations":[{"id":7242,"text":"Wisconsin Department of Natural Resources, Madison, WI, USA","active":true,"usgs":false}],"preferred":false,"id":413470,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We assessed the relative influences of elevation, channel slope, and stream width on the occurrences of 15 native warmwater fish species among 152 reaches scattered across the North Platte River drainage of Wyoming at the interface of the Great Plains and Rocky Mountains. Most species were collected in reaches that were lower in elevation, had lower channel slopes, and were wider than the medians of the 152 sampled reaches. Several species occurred over a relatively narrow range of elevation, channel slope, or stream width among the sampled reaches, but the distributions of some species appeared to extend beyond the ranges of the sampled reaches. We identified competing logistic-regression models that accounted for the occurrence of individual species using the information-theoretic approach. Linear logistic-regression models accounted for patterns in the data better than curvilinear models for all species. The highest ranked models included channel slope for seven species, elevation for six species, stream width for one species, and both channel slope and stream width for one species.

Precipitation-driven river discharge and regional temperature variability are the primary influences on Chesapeake Bay salinity and water temperature, respectively. We first calibrated modern ??18 Owater to salinity and applied this relationship to calculate trends in paleosalinity from the ??18 Oforam, correcting for changes in water temperature estimated from ostracode Mg /Ca ratios. The results indicate a much drier early Holocene in which mean paleosalinity was ???28 ppt in the northern bay, falling ???25% to ???20 ppt during the late Holocene. Early Holocene Mg/Ca-derived temperatures varied in a relatively narrow range of 13?? to 16??C with a mean temperature of 14.2??C and excursions above 16??C; the late Holocene was on average cooler (mean temperature of 12.8??C). In addition to the large contrast between early and late Holocene regional climate conditions, multidecadal (20-40 years) salinity and temperature variability is an inherent part of the region's climate during both the early and late Holocene, including the Medieval Warm Period and Little Ice Age. These patterns are similar to those observed during the twentieth century caused by NAO-related processes. Comparison of the midlatitude Chesapeake Bay salinity record with tropical climate records of Intertropical Convergence Zone fluctuations inferred from the Cariaco Basin titanium record suggests an anticorrelation between precipitation in the two regions at both millennial and centennial timescales.

The relationship of disturbance by military training to plant species richness and composition on two soils (Foard and Lawton) in a mixed prairie area was investigated. Track cover (cover of vehicle disturbance to the soil) and soil organic carbon were selected as measures of short- and long-term disturbance, respectively. Soil and vegetation data, collected in 1-m 2 quadrats, were analyzed at three spatial scales (60, 10, and 1 m2). Plant species richness peaked at intermediate levels of soil organic carbon at the 10-m2 and 1-m2 spatial scales on both the Lawton and Foard soils, and at intermediate levels of track cover at all three spatial scales on the Foard soil. Species composition differed across the disturbance gradient on the Foard soil but not on the Lawton soil. Disturbance increased total plant species richness on the Foard soil. The authors conclude that disturbance up to intermediate levels can be used to maintain biodiversity by enriching the plant species pool. ?? 2005 Springer Science+Business Media, Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00267-004-0373-6","issn":"0364152X","usgsCitation":"Leis, S., Engle, D.M., Leslie, D., and Fehmi, J., 2005, Effects of short- and long-term disturbance resulting from military maneuvers on vegetation and soils in a mixed prairie area: Environmental Management, v. 36, no. 6, p. 849-861, https://doi.org/10.1007/s00267-004-0373-6.","startPage":"849","endPage":"861","numberOfPages":"13","costCenters":[],"links":[{"id":211156,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00267-004-0373-6"},{"id":238365,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"36","issue":"6","noUsgsAuthors":false,"publicationDate":"2005-10-07","publicationStatus":"PW","scienceBaseUri":"505a07cae4b0c8380cd5182a","contributors":{"authors":[{"text":"Leis, S.A.","contributorId":18167,"corporation":false,"usgs":true,"family":"Leis","given":"S.A.","email":"","affiliations":[],"preferred":false,"id":413372,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Engle, David M.","contributorId":97225,"corporation":false,"usgs":true,"family":"Engle","given":"David","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":413375,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Leslie, David M.

Location: Interior Alaska. Methods: A logistic regression model was developed that predicts the potential equilibrium distribution of four major vegetation types: tundra, deciduous forest, black spruce forest and white spruce forest based on elevation, aspect, slope, drainage type, fire interval, average growing season temperature and total growing season precipitation. The model was run in three consecutive steps. The hierarchical logistic regression model was used to evaluate how scenarios of changes in temperature, precipitation and fire interval may influence the distribution of the four major vegetation types found in this region. Results: At the first step, tundra was distinguished from forest, which was mostly driven by elevation, precipitation and south to north aspect. At the second step, forest was separated into deciduous and spruce forest, a distinction that was primarily driven by fire interval and elevation. At the third step, the identification of black vs. white spruce was driven mainly by fire interval and elevation. The model was verified for Interior Alaska, the region used to develop the model, where it predicted vegetation distribution among the steps with an accuracy of 60-83%. When the model was independently validated for north-west Canada, it predicted vegetation distribution among the steps with an accuracy of 53-85%. Black spruce remains the dominant vegetation type under all scenarios, potentially expanding most under warming coupled with increasing fire interval. White spruce is clearly limited by moisture once average growing season temperatures exceeded a critical limit (+2 ??C). Deciduous forests expand their range the most when any two of the following scenarios are combined: decreasing fire interval, warming and increasing precipitation. Tundra can be replaced by forest under warming but expands under precipitation increase. Main conclusion: The model analyses agree with current knowledge of the responses of vegetation types to climate change and provide further insight into drivers of vegetation change. ?? 2005 Blackwell Publishing Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Biogeography","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2699.2004.01185.x","issn":"03050270","usgsCitation":"Calef, M., McGuire, A., Epstein, H., Rupp, T., and Shugart, H., 2005, Analysis of vegetation distribution in Interior Alaska and sensitivity to climate change using a logistic regression approach: Journal of Biogeography, v. 32, no. 5, p. 863-878, https://doi.org/10.1111/j.1365-2699.2004.01185.x.","startPage":"863","endPage":"878","numberOfPages":"16","costCenters":[],"links":[{"id":212996,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2699.2004.01185.x"},{"id":240572,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"32","issue":"5","noUsgsAuthors":false,"publicationDate":"2005-04-29","publicationStatus":"PW","scienceBaseUri":"5059eb48e4b0c8380cd48d23","contributors":{"authors":[{"text":"Calef, M.P.","contributorId":55213,"corporation":false,"usgs":true,"family":"Calef","given":"M.P.","email":"","affiliations":[],"preferred":false,"id":423614,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McGuire, A.

Atmospheric input was determined for wet-only and vegetative throughfall components. Annual throughfall fluxes were significantly enriched over incident precipitation for most elements, although some elements exhibited evidence of canopy release (Mn) or preferential uptake (As, Cr, and Se). Stream export was gauged based on systematic sampling under varied flow regimes. Particle loading appears to contribute significantly to watershed export (&gt; 10%) for only As, Pb, and Fe, and then only during large precipitation/runoff events. The degree of watershed transmission for each trace element was evaluated based on a comparison of total, net atmospheric input (throughfall) to stream export over an annual hydrologic cycle. This comparison indicates that the atmospheric input of some elements (Al, Cd, Ni, Zn) is effectively transmitted through the watershed, but other elements (Pb, As, Se, Fe, Cr, Cu) appear to be strongly sequestered, in the respective orders noted. Results suggest that precipitation and subsequent soil pH are the primary factors that determine the mobility of sequestered trace element phases.</p><p class=\"Para\">To further resolve primary atmospheric and secondary weathering components, the geochemical model NETPATH was applied. Results indicate that minerals dissolved include chlorite, plagioclase feldspar, epidote, and potassium feldspar; phases formed were kaolinite, pyrite, and silica. The model also indicates that weathering processes contribute negligible amounts of trace elements to stream export, indicative of the unreactive orthoquartzite bedrock lithology underlying the watershed.

Of particular interest is to describe how the distribution of distance to the outlet changes as a function of network size. In this paper, networks are modeled as random self-similar rooted tree graphs and scaling of distance to the root is studied using methods in stochastic branching theory. In particular, the asymptotic expectation of the width function (number of nodes as a function of distance to the outlet) is derived under conditions on the replacement generators. It is demonstrated further that the branching number describing rate of growth of node distance to the outlet is identical to the length ratio under a Horton-Strahler ordering scheme as order gets large, again under certain restrictions on the generators. These results are discussed in relation to drainage basin allometry and an application to an actual drainage network is presented. ??

Every year millions of people visit the 500 plus recreational beaches in the Great Lakes. An increasing public health risk has been suggested with increased evidence of fecal contamination at the shoreline. To investigate the transport and fate of fecal pollution at Great Lakes beaches and the health risk associated with swimming at these beaches, the near-shore waters of Mt Baldy Beach, Lake Michigan and Trail Creek, a tributary discharging into the lake were examined for fecal pollution indicators. A model of surf zone hydrodynamics coupled with a transport model with first-order inactivation of pollutant was used to understand the relative importance of different processes operating in the surf zone (e.g. physical versus biological processes). The Enterococcus human fecal pollution marker, which targets a putative virulence factor, the enterococcal surface protein (esp) in Enterococcus faecium, was detected in 2/28 samples (7%) from the tributaries draining into Lake Michigan and in 6/30 samples (20%) from Lake Michigan beaches. Preliminary analysis suggests that the majority of fecal indicator bactateria variation and water quality changes at the beaches can be explained by inputs from the influential stream and hydrometeorological conditions. Using modeling methods to predict impaired water quality may help reduce potential health threats to recreational visitors.","largerWorkTitle":"Proceedings of MTS/IEEE OCEANS, 2005","conferenceTitle":"MTS/IEEE OCEANS, 2005","conferenceDate":"18 September 2005 through 23 September 2005","conferenceLocation":"Washington, DC","language":"English","doi":"10.1109/OCEANS.2005.1639995","isbn":"0933957343; 9780933957343","usgsCitation":"Molloy, S., Liu, L., Phanikumar, M., Jenkins, T., Wong, M., Rose, J., Whitman, R., Shively, D., and Nevers, M., 2005, The presence and near-shore transport of human fecal pollution in Lake Michigan beaches, <i>in</i> Proceedings of MTS/IEEE OCEANS, 2005, v. 2005, Washington, DC, 18 September 2005 through 23 September 2005, https://doi.org/10.1109/OCEANS.2005.1639995.","costCenters":[],"links":[{"id":211081,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1109/OCEANS.2005.1639995"},{"id":238254,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2005","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505baec9e4b08c986b324337","contributors":{"authors":[{"text":"Molloy, S.L.","contributorId":51527,"corporation":false,"usgs":true,"family":"Molloy","given":"S.L.","email":"","affiliations":[],"preferred":false,"id":413339,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Liu, L.B.","contributorId":62404,"corporation":false,"usgs":true,"family":"Liu","given":"L.B.","email":"","affiliations":[],"preferred":false,"id":413341,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Phanikumar, M.S.","contributorId":83328,"corporation":false,"usgs":true,"family":"Phanikumar","given":"M.S.","affiliations":[],"preferred":false,"id":413345,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jenkins, T.M.","contributorId":77357,"corporation":false,"usgs":true,"family":"Jenkins","given":"T.M.","email":"","affiliations":[],"preferred":false,"id":413343,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wong, M.V.","contributorId":16645,"corporation":false,"usgs":true,"family":"Wong","given":"M.V.","email":"","affiliations":[],"preferred":false,"id":413338,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Rose, J.B.","contributorId":60825,"corporation":false,"usgs":true,"family":"Rose","given":"J.B.","email":"","affiliations":[],"preferred":false,"id":413340,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Whitman, R.L.","contributorId":69750,"corporation":false,"usgs":true,"family":"Whitman","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":413342,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Shively, D.A.","contributorId":78123,"corporation":false,"usgs":true,"family":"Shively","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":413344,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Nevers, M.B.","contributorId":13787,"corporation":false,"usgs":true,"family":"Nevers","given":"M.B.","email":"","affiliations":[],"preferred":false,"id":413337,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

These wire-line logs provide estimates of sonic velocities and densities for primarily Upper Cretaceous to Pliocene clastic rocks between 0.1 - and 5.6-km depth to an average depth of 1.8 km. Regional differences in the sonic velocities and densities in these basins largely 1reflect variations in the lithology, depth of burial, porosity, and grain size of the strata, but not necessarily formation age. For example, Miocene basin filling strata west of the Calaveras Fault exhibit higher sonic velocities and densities than older but finer-grained and/or higher-porosity rocks of the Upper Cretaceous Great Valley Sequence. As another example, hard Eocene sandstones west of the San Andreas Fault have much higher impedances than Eocene strata, mainly higher-porosity sandstones and shales, located to the east of this fault, and approach those expected for Franciscan Complex basement rocks. Basement penetrations define large impedence contrasts at the sediment/basement contact along the margins of several basins, where Quaternary, Pliocene, and even Miocene deposits directly overlie Franciscan or Salinian basement rocks at depths as much as 1.7 km. In contrast, in the deepest, geographic centers of the basins, such logs exhibit only a modest impedance contrast at the sediment/basement contact at depths exceeding 2 km. Prominent (up to 1 km/sec) and thick (up to several hundred meters) velocity and density reversals in the logs refute the common assumption that velocities and densities increase monotonically with depth.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120050025","issn":"00371106","usgsCitation":"Brocher, T., 2005, A regional view of urban sedimentary basins in Northern California based on oil industry compressional-wave velocity and density logs: Bulletin of the Seismological Society of America, v. 95, no. 6, p. 2093-2114, https://doi.org/10.1785/0120050025.","startPage":"2093","endPage":"2114","numberOfPages":"22","costCenters":[],"links":[{"id":209058,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120050025"},{"id":235243,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"95","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e543e4b0c8380cd46c4c","contributors":{"authors":[{"text":"Brocher, T.M. 0000-0002-9740-839X","orcid":"https://orcid.org/0000-0002-9740-839X","contributorId":69994,"corporation":false,"usgs":true,"family":"Brocher","given":"T.M.","affiliations":[],"preferred":false,"id":413311,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
