This study validated two dilution simple n models to estimate chloramine-T environmental introduction concentrations by comparing measured and predicted chloramine-T concentrations using the US Geological Survey's Upper Midwest Environmental Sciences Center aquaculture facility effluent as an example. The hydraulic characteristics of our treated raceway and effluent and the accuracy of our water flow rate measurements were confirmed with the marker dye rhodamine WT. We also used the rhodamine WT data to develop dilution models that would (1) estimate the chloramine-T concentration at a given time and location in the effluent system and (2) estimate the average chloramine-T concentration at a given location over the entire discharge period. To test our models, we predicted the chloramine-T concentration at two sample points based on effluent flow and the maintenance of chloramine-T at 20 mg/l for 60 min in the same raceway used with rhodamine WT. The effluent sample points selected (sample points A and B) represented 47 and 100% of the total effluent flow, respectively. Sample point B is-analogous to the discharge of a hatchery that does not have a detention lagoon, i.e. The sample site was downstream of the last dilution water addition following treatment. We then applied four chloramine-T flow-through treatments at 20mg/l for 60 min and measured the chloramine-T concentration in water samples collected every 15 min for about 180 min from the treated raceway and sample points A and B during and after application. The predicted chloramine-T concentration at each sampling interval was similar to the measured chloramine-T concentration at sample points A and B and was generally bounded by the measured 90% confidence intervals. The predicted aver,age chloramine-T concentrations at sample points A or B (2.8 and 1.3 mg/l, respectively) were not significantly different (P &gt; 0.05) from the average measured chloramine-T concentrations (2.7 and 1.3 mg/l, respectively). The close agreement between our predicted and measured chloramine-T concentrations indicate either of the dilution models could be used to adequately predict the chloramine-T environmental introduction concentration in Upper Midwest Environmental Sciences Center effluent.&nbsp;</p>","language":"English","publisher":"ScienceDirect","doi":"10.1016/j.aquaeng.2003.11.001","usgsCitation":"Gaikowski, M., Larson, W., Steuer, J.J., and Gingerich, W., 2004, Validation of two dilution models to predict chloramine-T concentrations in aquaculture facility effluent: Aquacultural Engineering, v. 30, no. 3-4, p. 127-140, https://doi.org/10.1016/j.aquaeng.2003.11.001.","productDescription":"14 p.","startPage":"127","endPage":"140","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":133965,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"30","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae3e4b07f02db6890d2","contributors":{"authors":[{"text":"Gaikowski, M.P. 0000-0002-6507-9341","orcid":"https://orcid.org/0000-0002-6507-9341","contributorId":51685,"corporation":false,"usgs":true,"family":"Gaikowski","given":"M.P.","affiliations":[],"preferred":false,"id":312336,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Larson, W.J.","contributorId":83489,"corporation":false,"usgs":true,"family":"Larson","given":"W.J.","email":"","affiliations":[],"preferred":false,"id":312338,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Steuer, J.

There was no effect of low-level experimental disturbance or an underwater seismic survey on site fidelity of molting Long-tailed Ducks. Birds molting along a relatively consistent habitat gradient were more likely to move than those molting in a fragmented habitat. While flocks of birds are consistently observed in the same locations, these data suggest considerable turnover within these aggregations. These results, in conjunction with other studies, suggest that forage is relatively uniformly distributed within lagoons.

Unlike high-head dams that preclude fish passage (unless they are equipped with fishways), the dams on the upper Mississippi River are typically low-head dams with bottom release gates that may allow fish passage under certain conditions. We evaluated the relation of dam head and river discharge to the passage of radio-tagged paddlefish through dams in the upper Mississippi River. Radio transmitters were surgically implanted into 71 paddlefish from Navigation Pools 5A and 8 of the upper Mississippi River and from two tributary rivers during fall 1994 through fall 1996. We tracked paddlefish through September 1997 and documented 53 passages through dams, 20 upstream and 33 downstream. Passages occurred mostly during spring (71%) but also occurred sporadically during summer and fall (29%). Spring passages varied among years in response to hydrologic conditions. We evaluated patterns in upstream and downstream passages with Cox proportional hazard regression models. Model results indicated that dam head height strongly affected the upstream passage of paddlefish but not the downstream passage. Several paddlefish, however, passed upstream through a dam during periods when the minimum head at the dam was substantial (<span>≥1 m</span>). In these cases, we hypothesize that paddlefish moved upstream through the lock chamber.</p>","language":"English","publisher":"Wiley","doi":"10.1577/T02-161","usgsCitation":"Zigler, S.J., Dewey, M.R., Knights, B., Runstrom, A., and Steingraeber, M., 2004, Hydrologic and hydraulic factors affecting passage of paddlefish through dams in the Upper Mississippi River: Transactions of the American Fisheries Society, v. 133, no. 1, p. 160-172, https://doi.org/10.1577/T02-161.","productDescription":"13 p.","startPage":"160","endPage":"172","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":178205,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Illinois, Iowa, Minnesota, Wisconsin","otherGeospatial":"Upper Mississippi River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -92.98828125,\n              44.68427737181225\n            ],\n            [\n              -91.58203125,\n              43.389081939117496\n            ],\n            [\n              -90.703125,\n              42.16340342422401\n            ],\n            [\n              -91.4501953125,\n              40.68063802521456\n            ],\n            [\n              -90.3955078125,\n              40.97989806962013\n            ],\n            [\n              -89.8681640625,\n              42.06560675405716\n            ],\n            [\n              -90.52734374999999,\n              43.03677585761058\n            ],\n            [\n              -91.58203125,\n              44.59046718130883\n            ],\n            [\n              -92.94433593749999,\n              45.27488643704891\n            ],\n            [\n              -92.63671874999997,\n              45.82879925192134\n            ],\n            [\n              -92.98828125,\n              44.68427737181225\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"133","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a29e4b07f02db61180c","contributors":{"authors":[{"text":"Zigler, S.

Their influence on Zn bioavailability was also evaluated by a parallel, 10‐d amphipod (<i>Leptocheirus plumulosus</i>) mortality test at 5, 20, and 85 d of equilibration. During the equilibration, AVS increased (up to twofold) with spiked Zn concentration ([Zn]), whereas Zn‐simultaneously extracted metals ([SEM]; Zn with AVS) remained relatively constant. Concentrations of Zn in PW decreased most rapidly during the initial 30 d and by 11‐ to 23‐fold during the whole 95‐d equilibration period. The apparent partitioning coefficient (<i>K</i><sub>pw</sub>, ratio of [Zn] in SEM to PW) increased by 10‐ to 20‐fold with time and decreased with spiked [Zn] in sediments. The decrease of PW [Zn] could be explained by a combination of changes in AVS and redistribution of Zn into more insoluble phases as the sediment aged. Amphipod mortality decreased significantly with the equilibration time, consistent with decrease in dissolved [Zn]. The median lethal concentration (LC50) value (33 μM) in the second bioassay, conducted after 20 d of equilibration, was twofold the LC50 in the initial bioassay at 5 d of equilibration, probably because of the change of dissolved Zn speciation. Sediment bioassay protocols employing a short equilibration time and high spiked metal concentrations could accentuate partitioning of metals to the dissolved phase and shift the pathway for metal exposure toward the dissolved phase.</p></div></div>","language":"English","publisher":"SETAC","doi":"10.1897/03-176","issn":"07307268","usgsCitation":"Lee, J., Lee, B., Luoma, S., and Yoo, H., 2004, Importance of equilibration time in the partitioning and toxicity of zinc in spiked sediment bioassays: Environmental Toxicology and Chemistry, v. 23, no. 1, p. 65-71, https://doi.org/10.1897/03-176.","productDescription":"7 p.","startPage":"65","endPage":"71","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":478117,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.513.6906","text":"External Repository"},{"id":238072,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":210962,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1897/03-176"}],"volume":"23","issue":"1","noUsgsAuthors":false,"publicationDate":"2004-01-01","publicationStatus":"PW","scienceBaseUri":"505a3938e4b0c8380cd6184d","contributors":{"authors":[{"text":"Lee, J.-S.","contributorId":15787,"corporation":false,"usgs":true,"family":"Lee","given":"J.-S.","email":"","affiliations":[],"preferred":false,"id":415103,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lee, B.-G.","contributorId":11777,"corporation":false,"usgs":true,"family":"Lee","given":"B.-G.","email":"","affiliations":[],"preferred":false,"id":415102,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Luoma, S.

In order to distinguish between these two possible interpretations we conducted a photometric analysis of three of the most prominent of these features using six of the highest quality images from the September 22, 2001 Deep Space 1 (DS1) flyby. We find that: 1. The radiance in the darkest parts of each feature increases as phase angle decreases, similarly to the radiance behavior of the higher albedo surrounding terrain. The dark features could be either fully illuminated low albedo spots or, alternatively, they could be depressions. No part of any of the three regions was in full shadow. 2. One of the regions has a radiance profile consistent with a rimmed depression, the second, with a simple depression with no rim, and the third with a low albedo spot. 3. The regolith particles are backscattering and carbon black is one of the few candidate regolith materials that might explain this low albedo. We conclude that Borrelly's surface is geologically complex to the limit of resolution of the images with a combination complex topography, pits, troughs, peaks and ridges, and some very dark albedo markings, perhaps a factor of two to three darker than the average 3-4% albedo of the surrounding terrains. Our technique utilizing measured radiance profiles through the dark regions is able to discriminate between rimmed depressions, rimless depressions and simple albedo changes not associated with topography. ?? 2003 Elsevier Inc.

We review the history of modifications and alternatives for estimating nest survival, with a focus on four techniques: apparent nest success, the Mayfield estimator, the Stanley method, and program MARK. The widely used Mayfield method avoids the known positive bias inherent in apparent nest success by estimating daily survival rates using the number of exposure days, eliminating the need to monitor nests from initiation. Concerns that some of Mayfield's assumptions were restrictive stimulated the development of new techniques. Stanley's method allows for calculation of stage-specific daily survival rates when transition and failure dates are unknown, and eliminates Mayfield's assumption that failure occurred midway through the nest-check interval. Program MARK obviates Mayfield's assumption of constant daily survival within nesting stages and evaluates variation in nest survival as a function of biologically relevant factors. These innovative methods facilitate the evaluation of nest survival using an information-theoretic approach. We illustrate use of these methods with Lark Bunting (</span><i>Calamospiza melanocorys</i><span>) nest data from the Pawnee National Grassland, Colorado. Nest survival estimates calculated using Mayfield, Stanley, and MARK methods were similar, but apparent nest success estimates ranged 1– 24% greater than the other estimates. MARK analysis revealed that survival of Lark Bunting nests differed between site–year groups, declined with both nest age and time in season, but did not vary with weather parameters. We encourage researchers to use these approaches to gain reliable and meaningful nest survival estimates.</span></p>","language":"English","publisher":"American Ornitological Society","doi":"10.1093/condor/106.3.472","usgsCitation":"Jehle, G., Yackel Adams, A., Savidge, J.A., and Skagen, S., 2004, Nest survival estimation: A review of alternatives to the Mayfield estimator: The Condor, v. 106, no. 3, p. 472-484, https://doi.org/10.1093/condor/106.3.472.","productDescription":"13 p.","startPage":"472","endPage":"484","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":478055,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1093/condor/106.3.472","text":"Publisher Index Page"},{"id":134270,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"106","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6ae92d","contributors":{"authors":[{"text":"Jehle, G.","contributorId":27414,"corporation":false,"usgs":false,"family":"Jehle","given":"G.","email":"","affiliations":[],"preferred":false,"id":322477,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yackel Adams, A.

We examined whether early growth, which is primarily governed by environmental conditions, also affects the probability that individuals that survive their first year enter the breeding population. We used logistic regression on a sample of Black Brant (<i>Branta bernicla nigricans</i>) that were weighed at a known age in their first summer and observed during winter (indicating that they had survived the principal mortality period in their first year) to study whether early growth influenced the probability that those individuals would be recruited into the breeding population. We also examined the effects of cohort (1986-1996), sex, age when measured, and area where individuals were reared. The model with the lowest Akaike's Information Criterion score contained body mass, age (days) at measurement, cohort, sex, and brood-rearing area. Models that included variable mass had 85% of the cumulative model weight of the models we considered, indicating that gosling mass had a substantial effect on probability of them entering the breeding population. Females were more likely to be detected breeding than males, which is consistent with the differential fidelity of the sexes. Of individuals that survived the first year, larger goslings were more likely to become breeders. More recent cohorts were less likely to have been detected as breeders.

The mapping, which detects forest-floor relief of as little as 15 cm, reveals scarps along geophysical lineaments that separate areas of Holocene uplift and subsidence. Along one such line of scarps, we found that a fault warped the ground surface between A.D. 770 and 1160. This reverse fault, which projects through Tacoma, Washington, bounds the southern and western sides of the Seattle uplift. The northern flank of the Seattle uplift is bounded by a reverse fault beneath Seattle that broke in A.D. 900-930. Observations of tectonic scarps along the Tacoma fault demonstrate that active faulting with associated surface rupture and ground motions pose a significant hazard in the Puget Sound region.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/G19914.1","issn":"00917613","usgsCitation":"Sherrod, B., Brocher, T., Weaver, C., Bucknam, R., Blakely, R., Kelsey, H., Nelson, A., and Haugerud, R., 2004, Holocene fault scarps near Tacoma, Washington, USA: Geology, v. 32, no. 1, p. 9-12, https://doi.org/10.1130/G19914.1.","startPage":"9","endPage":"12","numberOfPages":"4","costCenters":[],"links":[{"id":210984,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/G19914.1"},{"id":238107,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"32","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a31e6e4b0c8380cd5e31d","contributors":{"authors":[{"text":"Sherrod, B.L.","contributorId":68937,"corporation":false,"usgs":true,"family":"Sherrod","given":"B.L.","email":"","affiliations":[],"preferred":false,"id":415270,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"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":415271,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Weaver, C.S.","contributorId":57874,"corporation":false,"usgs":true,"family":"Weaver","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":415268,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bucknam, R.C.","contributorId":35744,"corporation":false,"usgs":true,"family":"Bucknam","given":"R.C.","affiliations":[],"preferred":false,"id":415266,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Blakely, R.J. 0000-0003-1701-5236","orcid":"https://orcid.org/0000-0003-1701-5236","contributorId":70755,"corporation":false,"usgs":true,"family":"Blakely","given":"R.J.","affiliations":[],"preferred":false,"id":415272,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Kelsey, H.M.","contributorId":84300,"corporation":false,"usgs":true,"family":"Kelsey","given":"H.M.","email":"","affiliations":[],"preferred":false,"id":415273,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Nelson, A.R. 0000-0001-7117-7098","orcid":"https://orcid.org/0000-0001-7117-7098","contributorId":55078,"corporation":false,"usgs":true,"family":"Nelson","given":"A.R.","affiliations":[],"preferred":false,"id":415267,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Haugerud, R.","contributorId":59618,"corporation":false,"usgs":true,"family":"Haugerud","given":"R.","email":"","affiliations":[],"preferred":false,"id":415269,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

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.

The ESM is evaluated through its application at two lakes in New England, one where water seeps into the lake and one where water seeps out of the lake. The electromagnetic flowmeter replaces the seepage-meter bag and provides a continuous series of measurements from which temporal seepage processes can be investigated. It provides flow measurements over a range of three orders of magnitude, and contains no protruding components or moving parts. The ESM was used to evaluate duration of seepage disturbance following meter installation and indicated natural seepage rates resumed approximately one hour following meter insertion in a sandy lakebed. Lakebed seepage also varied considerably in response to lakebed disturbances, near-shore waves, and rain-falls, indicating hydrologic processes are occurring in shallow lakebed settings at time scales that have largely gone unobserved.","language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6584.2004.tb02451.x","issn":"0017467X","usgsCitation":"Rosenberry, D., and Morin, R.H., 2004, Use of an electromagnetic seepage meter to investigate temporal variability in lake seepage: Ground Water, v. 42, no. 1, p. 68-77, https://doi.org/10.1111/j.1745-6584.2004.tb02451.x.","productDescription":"10 p.","startPage":"68","endPage":"77","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":211008,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6584.2004.tb02451.x"},{"id":238143,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"42","issue":"1","noUsgsAuthors":false,"publicationDate":"2005-12-13","publicationStatus":"PW","scienceBaseUri":"505bbeb3e4b08c986b32972b","contributors":{"authors":[{"text":"Rosenberry, D.O. 0000-0003-0681-5641","orcid":"https://orcid.org/0000-0003-0681-5641","contributorId":38500,"corporation":false,"usgs":true,"family":"Rosenberry","given":"D.O.","affiliations":[],"preferred":true,"id":415277,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Morin, R.

With the 1957 Mw 8.3 Gobi-Altay, Mongolia, earthquake as the only other well-documented case of significant, nearly simultaneous rupture of both thrust and strike-slip faults, this feature of the 2002 Denali fault earthquake provides a unique opportunity to investigate the mechanisms responsible for development of these large, complex events. We find that the geometry of the faults and the orientation of the regional stress field caused slip on the Susitna Glacier fault to load the Denali fault. Several different stress orientations with oblique right-lateral motion on the Susitna Glacier fault replicate the triggering of rupture on the Denali fault about 10 sec after the rupture nucleates on the Susitna Glacier fault. However, generating slip directions compatible with measured surface offsets and kinematic source inversions requires perturbing the stress orientation from that determined with focal mechanisms of regional events. Adjusting the vertical component of the principal stress tensor for the regional stress field so that it is more consistent with a mixture of strike-slip and reverse faulting significantly improves the fit of the slip-rake angles to the data. Rotating the maximum horizontal compressive stress direction westward appears to improve the fit even further.","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120040614","usgsCitation":"Aagaard, B.T., Anderson, G., and Hudnut, K., 2004, Dynamic rupture modeling of the transition from thrust to strike-slip motion in the 2002 Denali fault earthquake, Alaska: Bulletin of the Seismological Society of America, v. 94, no. 6B, p.

It also explains a mathematical model of physical character parameters of quality of high-grade roads. This paper then discusses an algorithm of computing dispersion curves using adjacent channels. Shear velocity and physical character parameters are obtained by inversion of dispersion curves. The algorithm using adjacent channels to calculating dispersion curves eliminates average effects that exist by using multi-channels to obtain dispersion curves so that it improves longitudinal and transverse resolution of LR waves and precision of non-invasive detection, and also broadens its application fields. By analysis of modeling results of detached computation of the ground roll and real examples of detecting density and pressure strength of a high-grade roadbed, and by comparison of shallow seismic image method with borehole cores, we concluded that: 1 the abnormal scale and configuration obtained by LR waves are mostly the same as the result of shallow seismic image method; 2 an average relative error of density obtained from LR waves inversion is 1.6% comparing with borehole coring; 3 transient LR waves in detecting density and pressure strength of a high-grade roadbed is feasible and effective.","largerWorkTitle":"Progress in Environmental and Engineering Geophysics: Proceedings of the International Conference on Environmental and Engineering Geophysics, ICEEG 2004","conferenceTitle":"Progress in Environmental and Engineering Geophysics: Proceedings of the International Conference on Environmental and Engineering Geophysics, ICEEG 2004","conferenceDate":"6 June 2004 through 9 June 2004","conferenceLocation":"Wuhan","language":"English","isbn":"1880132974","usgsCitation":"Liu, J., Xia, J., Luo, Y., Li, X., and Xu, S., 2004, Extracting transient Rayleigh wave and its application in detecting quality of highway roadbed, <i>in</i> Progress in Environmental and Engineering Geophysics: Proceedings of the International Conference on Environmental and Engineering Geophysics, ICEEG 2004, Wuhan, 6 June 2004 through 9 June 2004, p. 122-130.","startPage":"122","endPage":"130","numberOfPages":"9","costCenters":[],"links":[{"id":234630,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0e5be4b0c8380cd533ee","contributors":{"editors":[{"text":"Chen C.Xia J.","contributorId":128353,"corporation":true,"usgs":false,"organization":"Chen C.Xia J.","id":536585,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Liu, J.","contributorId":23672,"corporation":false,"usgs":false,"family":"Liu","given":"J.","affiliations":[],"preferred":false,"id":408590,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Xia, J.","contributorId":63513,"corporation":false,"usgs":true,"family":"Xia","given":"J.","email":"","affiliations":[],"preferred":false,"id":408592,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Luo, Y.","contributorId":28417,"corporation":false,"usgs":true,"family":"Luo","given":"Y.","email":"","affiliations":[],"preferred":false,"id":408591,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Li, X.","contributorId":67635,"corporation":false,"usgs":true,"family":"Li","given":"X.","email":"","affiliations":[],"preferred":false,"id":408593,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Xu, S.","contributorId":84954,"corporation":false,"usgs":true,"family":"Xu","given":"S.","email":"","affiliations":[],"preferred":false,"id":408594,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

For HLP, the Re content was 283.8 ± 6.2 μg g</span><sup>−1</sup><span>,&nbsp;</span><sup>187</sup><span>Os was 659 ± 14 ng g</span><sup>−1</sup><span>&nbsp;and the Re-Os model age was 221.4 ± 5.6 Ma. For JDC, the Re content was 17.39 ± 0.32 μg g</span><sup>−1</sup><span>,&nbsp;</span><sup>187</sup><span>Os was 25.46 ± 0.60 ng g</span><sup>−1</sup><span>&nbsp;and the Re-Os model age was 139.6 ± 3.8 Ma. Uncertainties for both certified reference materials are stated at the 95% level of confidence. Three laboratories (from three countries: PR. China, USA, Sweden) joined in the certification programme. These certified reference materials are primarily useful for Re-Os dating of molybdenite, sulfides, black shale, etc.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1751-908X.2004.tb01042.x","usgsCitation":"Du, A., Wu, S., Sun, D., Wang, S., Qu, W., Markey, R., Stain, H., Morgan, J., and
