The widespread presence of \"softened\" Martian landforms (such as impact craters) can be attributed to viscous creep of subsurface ground ice. We present laboratory experiments designed to determine the minimum amount of ice necessary to mobilize topography within Martian permafrost. Our results show that the jammed-to-mobile transition of icy sand packs neither occurs at fixed ice content nor is dependent on temperature or stress, but instead correlates strongly with the maximum dry packing density of the sand component. Viscosity also changes rapidly near the mobility transition. The results suggest a potentially lower minimum volatile inventory for the impact-pulverized megaregolith of Mars. Furthermore, the long-term preservation of partially relaxed craters implies that the ice content of Martian permafrost has remained close to that at the mobility transition throughout Martian history.

Current design methods are based upon anecdotal information applicable to a narrow range of channel conditions. The complex flow patterns and performance of rock weirs is not well understood. Without accurate understanding of their hydraulics, designers cannot address the failure mechanisms of these structures. Flow characteristics such as jets, near bed velocities, recirculation, eddies, and plunging flow govern scour pool development. These detailed flow patterns can be replicated using a 3D numerical model. Numerical studies inexpensively simulate a large number of cases resulting in an increased range of applicability in order to develop design tools and predictive capability for analysis and design. The analysis and results of the numerical modeling, laboratory modeling, and field data provide a process-based method for understanding how structure geometry affects flow characteristics, scour development, fish passage, water delivery, and overall structure stability. Results of the numerical modeling allow designers to utilize results of the analysis to determine the appropriate geometry for generating desirable flow parameters. The end product of this research will develop tools and guidelines for more robust structure design or retrofits based upon predictable engineering and hydraulic performance criteria. ?? 2009 ASCE.","largerWorkTitle":"Proceedings of World Environmental and Water Resources Congress 2009 - World Environmental and Water Resources Congress 2009: Great Rivers","conferenceTitle":"World Environmental and Water Resources Congress 2009: Great Rivers","conferenceDate":"17 May 2009 through 21 May 2009","conferenceLocation":"Kansas City, MO","language":"English","doi":"10.1061/41036(342)328","isbn":"9780784410363","usgsCitation":"Holmquist-Johnson, C.L., 2009, Numerical analysis of the performance of rock weirs: Effects of structure configuration on local hydraulics, <i>in</i> Proceedings of World Environmental and Water Resources Congress 2009 - World Environmental and Water Resources Congress 2009: Great Rivers, v. 342, Kansas City, MO, 17 May 2009 through 21 May 2009, p. 3244-3255, https://doi.org/10.1061/41036(342)328.","startPage":"3244","endPage":"3255","numberOfPages":"12","costCenters":[],"links":[{"id":216193,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/41036(342)328"},{"id":244047,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"342","noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"505a68e9e4b0c8380cd73a7c","contributors":{"authors":[{"text":"Holmquist-Johnson, C.

This approach has many advantages over traditional modeling approaches, including being faster and less expensive, more comprehensive in its use of available data, and more accurate in representing a system's physical processes.

Here we present a novel approach that solves mass-balance equations for two cores algebraically to estimate contaminant contributions to sediment from direct atmospheric fallout and from watershed and in-lake focusing. The model is applied to excess <sup>210</sup>Pb and Hg in cores from Hobbs Lake, a high-altitude lake in Wyoming. Model results for excess <sup>210</sup>Pb are consistent with estimates of fallout and focusing factors computed using excess <sup>210</sup>Pb burdens in lake cores and soil cores from the watershed and model results for Hg fallout are consistent with fallout estimated using the soil-core-based <sup>210</sup>Pb focusing factors. The lake cores indicate small increases in mercury deposition beginning in the late 1800s and large increases after 1940, with the maximum at the tops of the cores of 16-20 ??g/m <sup>2</sup>year. These results suggest that global Hg emissions and possibly regional emissions in the western United States are affecting the north-central Rocky Mountains. Hg fallout estimates are generally consistent with fallout reported from an ice core from the nearby Upper Fremont Glacier, but with several notable differences. The model might not work for lakes with complex geometries and multiple sediment inputs, but for lakes with simple geometries, like Hobbs, it can provide a quantitative approach for evaluating sediment focusing and estimating contaminant fallout.","language":"English","publisher":"ACS","doi":"10.1021/es801490c","issn":"0013936X","usgsCitation":"Van Metre, P., and Fuller, C.C., 2009, Dual-core mass-balance approach for evaluating mercury and<sup>210</sup>Pb atmospheric fallout and focusing to lakes: Environmental Science & Technology, v. 43, no. 1, p. 26-32, https://doi.org/10.1021/es801490c.","productDescription":"7 p.","startPage":"26","endPage":"32","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":244080,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216222,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es801490c"}],"volume":"43","issue":"1","noUsgsAuthors":false,"publicationDate":"2008-12-02","publicationStatus":"PW","scienceBaseUri":"505a0407e4b0c8380cd50752","contributors":{"authors":[{"text":"Van Metre, P.

There was general agreement about the direction of changes in the mean annual discharge and 90% discharge percentile predicted by the ensemble members, although a considerable range in the magnitude of predictions for the scenarios and catchments under consideration was obvious. Differences in the magnitude of the increase were attributed to the different mean annual actual evapotranspiration rates for each land use type. The ensemble of model runs was further analyzed with deterministic and probabilistic ensemble methods. The deterministic ensemble method based on a trimmed mean resulted in a single somewhat more reliable scenario prediction. The probabilistic reliability ensemble averaging (REA) method allowed a quantification of the model structure uncertainty in the scenario predictions. It was concluded that the use of a model ensemble has greatly increased our confidence in the reliability of the model predictions. ?? 2008 Elsevier Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Advances in Water Resources","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.advwatres.2008.06.009","issn":"03091708","usgsCitation":"Huisman, J.A., Breuer, L., Bormann, H., Bronstert, A., Croke, B., Frede, H., Graff, T., Hubrechts, L., Jakeman, A., Kite, G., Lanini, J., Leavesley, G., Lettenmaier, D., Lindstrom, G., Seibert, J., Sivapalan, M., Viney, N., and Willems, P., 2009, Assessing the impact of land use change on hydrology by ensemble modeling (LUCHEM) III: Scenario analysis: Advances in Water Resources, v. 32, no. 2, p. 159-170, https://doi.org/10.1016/j.advwatres.2008.06.009.","startPage":"159","endPage":"170","numberOfPages":"12","costCenters":[],"links":[{"id":476330,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/1885/57021","text":"External Repository"},{"id":216350,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.advwatres.2008.06.009"},{"id":244214,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"32","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059edeae4b0c8380cd49ad8","contributors":{"authors":[{"text":"Huisman, J.

Temporal and spatial variations in concentrations and loads of nutrients, pharmaceuticals, and organic wastewater compounds were observed, primarily related to a site's proximity to point-source discharges and stream-flow dynamics. ?? 2009 ASCE.","largerWorkTitle":"Proceedings of World Environmental and Water Resources Congress 2009 - World Environmental and Water Resources Congress 2009: Great Rivers","conferenceTitle":"World Environmental and Water Resources Congress 2009: Great Rivers","conferenceDate":"17 May 2009 through 21 May 2009","conferenceLocation":"Kansas City, MO","language":"English","doi":"10.1061/41036(342)461","isbn":"9780784410363","usgsCitation":"Wilkison, D., Armstrong, D., and Hampton, S., 2009, Water-quality assessment of the largely urban blue river basin, Metropolitan Kansas City, USA, 1998 to 2007, <i>in</i> Proceedings of World Environmental and Water Resources Congress 2009 - World Environmental and Water Resources Congress 2009: Great Rivers, v. 342, Kansas City, MO, 17 May 2009 through 21 May 2009, p. 4590-4598, https://doi.org/10.1061/41036(342)461.","startPage":"4590","endPage":"4598","numberOfPages":"9","costCenters":[],"links":[{"id":216106,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/41036(342)461"},{"id":243952,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"342","noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"505bcdd1e4b08c986b32e0ed","contributors":{"authors":[{"text":"Wilkison, D.H.","contributorId":39800,"corporation":false,"usgs":true,"family":"Wilkison","given":"D.H.","email":"","affiliations":[],"preferred":false,"id":452376,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Armstrong, D.J.","contributorId":64058,"corporation":false,"usgs":true,"family":"Armstrong","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":452377,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hampton, S.A.","contributorId":71790,"corporation":false,"usgs":true,"family":"Hampton","given":"S.A.","email":"","affiliations":[],"preferred":false,"id":452378,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

This model can be applied for cases where water temperature in a well or spring receives all or part of its water from a phreatic conduit. Heat transport in the conduit is simulated by using a physically-based heat-transport equation that accounts for inflow of diffuse flow from smaller openings and fissures in the surrounding aquifer during periods of low recharge. Additional diffuse flow that is within the zone of influence of the well or spring but has not interacted with the conduit is accounted for with a binary mixing equation to proportion these different water sources. The estimation of this proportion through inverse modeling is useful for the assessment of contaminant vulnerability and well-head or spring protection. The model was applied to 7 months of continuous temperature data for a sinking stream that recharges a conduit and a pumped well open to the Madison aquifer in western South Dakota. The simulated conduit-flow fraction to the well ranged from 2% to 31% of total flow, and simulated conduit velocity ranged from 44 to 353 m/d.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jhydrol.2009.09.024","issn":"00221694","usgsCitation":"Long, A., and Gilcrease, P., 2009, A one-dimensional heat-transport model for conduit flow in karst aquifers: Journal of Hydrology, v. 378, no. 3-4, p. 230-239, https://doi.org/10.1016/j.jhydrol.2009.09.024.","startPage":"230","endPage":"239","numberOfPages":"10","costCenters":[],"links":[{"id":243955,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216109,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jhydrol.2009.09.024"}],"volume":"378","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e4cae4b0c8380cd4692b","contributors":{"authors":[{"text":"Long, Andrew J.","contributorId":80023,"corporation":false,"usgs":false,"family":"Long","given":"Andrew J.","affiliations":[],"preferred":false,"id":452574,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gilcrease, P.C.","contributorId":58116,"corporation":false,"usgs":true,"family":"Gilcrease","given":"P.C.","email":"","affiliations":[],"preferred":false,"id":452573,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The objectives of this study were to investigate the relationship between ammonia volatilization and ??<sup>15</sup>N of dairy manure and the feasibility of estimating ammonia losses from a dairy facility using chemical markers. In Exp. 1, the N/P ratio in manure decreased by 30% in 14 d as cumulative ammonia losses increased exponentially. Delta <sup>15</sup>N of manure increased throughout the course of the experiment and ??<sup>15</sup>N of emitted ammonia increased (p &lt; 0.001) quadratically from -31??? to -15 ???. The relationship between cumulative ammonia losses and ??<sup>15</sup>N of manure was highly significant (p &lt; 0.001; r<sup>2</sup> = 0.76). In Exp. 2, using a mass balance approach, approximately half of the N excreted by dairy cows (Bos taurus) could not be accounted for in 24 h. Using N/P and N/K ratios in fresh and 24-h manure, an estimated 0.55 and 0.34 (respectively) of the N excreted with feces and urine could not be accounted for. This study demonstrated that chemical markers (P, K) can be successfully used to estimate ammonia losses from cattle manure. The relationship between manure ??<sup>15</sup>N and cumulative ammonia loss may also be useful for estimating ammonia losses. Although promising, the latter approach needs to be further studied and verified in various experimental conditions and in the field.

The models encompass a large range in inherent complexity and input requirements. In approximate order of decreasing complexity, they are DHSVM, MIKE-SHE, TOPLATS, WASIM-ETH, SWAT, PRMS, SLURP, HBV, LASCAM and IHACRES. The models are calibrated twice using different sets of input data. The two predictions from each model are then combined by simple averaging to produce a single-model ensemble. The 10 resulting single-model ensembles are combined in various ways to produce multi-model ensemble predictions. Both the single-model ensembles and the multi-model ensembles are shown to give predictions that are generally superior to those of their respective constituent models, both during a 7-year calibration period and a 9-year validation period. This occurs despite a considerable disparity in performance of the individual models. Even the weakest of models is shown to contribute useful information to the ensembles they are part of. The best model combination methods are a trimmed mean (constructed using the central four or six predictions each day) and a weighted mean ensemble (with weights calculated from calibration performance) that places relatively large weights on the better performing models. Conditional ensembles, in which separate model weights are used in different system states (e.g. summer and winter, high and low flows) generally yield little improvement over the weighted mean ensemble. However a conditional ensemble that discriminates between rising and receding flows shows moderate improvement. An analysis of ensemble predictions shows that the best ensembles are not necessarily those containing the best individual models. Conversely, it appears that some models that predict well individually do not necessarily combine well with other models in multi-model ensembles. The reasons behind these observations may relate to the effects of the weighting schemes, non-stationarity of the climate series and possible cross-correlations between models.

Our analysis suggested that conflict was scientized, rooted in worldviews, and aggravated by use of inflammatory symbols such as \"wilderness\" and \"bighorn sheep.\" Contested problem definitions, framed as matters of science, advanced factional interests largely by allocating the burden of proof and failing to disclose private concerns about well-being, affection, respect, skill and power. Decision processes were shaped by precepts of scientific management, and thus largely failed to foster civility, common ground, and a focus on common interests, and instead tended to exacerbate deprivations of dignity and respect. If the status quo continues, we foresee further erosion of human dignity because there are likely to be increases in system stressors, such as climate change and human population growth. The prognosis would be more hopeful if alternatives were adopted that entailed authoritative, equitable, and collaborative public decision-making processes that took into consideration national-level common interests such as the U.S. Endangered Species Act. ??

Even with the hurricanes, precipitation in the Bogue Phalia Basin for the months of June to October 2005 was below normal, and consequently, streamflow was below the long‐term average. Temperature profiles from the piezometers indicate that the Bogue Phalia was a gaining stream during most of this time, but relatively static streambed temperatures suggested long‐term data was warranted for heat‐based estimates of flux. However, the hurricanes caused a pair of sharp rises in stream stage over short periods of time, increasing the potential for rapid heat‐based modeling and for identification of the critical stage for flow reversal into the streambed. Heat‐based modeling fits of simulated‐to‐measured sediment temperatures show that once a critical stage was surpassed, flow direction reversed into the streambed.

We used pollen assemblages from transects of sediment cores spanning sawgrass ridges, sloughs, and ridge-slough transition zones to determine the timing of ridge and slough formation and to evaluate the response of components of the ridge and slough landscape to climate variability and 20th-century water management. These pollen data indicate that sawgrass ridges and sloughs have been vegetationally distinct from one another since initiation of the Everglades wetland in mid-Holocene time. Although the position and community composition of sloughs have remained relatively stable throughout their history, modern sawgrass ridges formed on sites that originally were occupied by marshes. Ridge formation and maturation were initiated during intervals of drier climate (the Medieval Warm Period and the Little Ice Age) when the mean position of the Intertropical Convergence Zone shifted southward. During these drier intervals, marsh taxa were more common in sloughs, but they quickly receded when precipitation increased. Comparison with regional climate records suggests that slough vegetation is strongly influenced by North Atlantic Oscillation variability, even under 20th-century water management practices. ?? 2009 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/08-0779.1","issn":"10510761","usgsCitation":"Bernhardt, C., and Willard, D., 2009, Response of the everglades ridge and slough landscape to climate variability and 20th-century water management: Ecological Applications, v. 19, no. 7, p. 1723-1738, https://doi.org/10.1890/08-0779.1.","startPage":"1723","endPage":"1738","numberOfPages":"16","costCenters":[],"links":[{"id":216083,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/08-0779.1"},{"id":243925,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"19","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaa75e4b0c8380cd86349","contributors":{"authors":[{"text":"Bernhardt, C.E.","contributorId":65554,"corporation":false,"usgs":true,"family":"Bernhardt","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":452729,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Willard, Debra  A. 0000-0003-4878-0942","orcid":"https://orcid.org/0000-0003-4878-0942","contributorId":85982,"corporation":false,"usgs":true,"family":"Willard","given":"Debra  A.","affiliations":[],"preferred":false,"id":452730,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The data were used to assess the factors influencing tailings seepage quality and to identify constraints for water treatment. Changes in seepage water quality after equilibration with atmospheric conditions were evaluated based on geochemical modelling. At Luikonlahti, annual and seasonal changes were also studied. Seepage quality was largely influenced by the tailings mineralogy, and the serpentine-rich, low sulphide Hitura tailings produced neutral mine drainage with high Ni. In contrast, drainage from the high sulphide, multi-metal tailings of Luikonlahti represented typical acid mine drainage with elevated contents of Zn, Ni, Cu, and Co. Other factors affecting the seepage quality included weathering of the tailings along the seepage flow path, process water input, local hydrological settings, and structural changes in the tailings impoundment. Geochemical modelling showed that pH increased and some heavy metals were adsorbed to Fe precipitates after net alkaline waters equilibrated with the atmosphere. In the net acidic waters, pH decreased and no adsorption occurred. A combination of aerobic and anaerobic treatments is proposed for Hitura seepages to decrease the sulphate and metal loading. For Luikonlahti, prolonged monitoring of the seepage quality is suggested instead of treatment, since the water quality is still adjusting to recent modifications to the tailings impoundment.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mine Water and the Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10230-008-0056-2","issn":"10259112","usgsCitation":"Heikkinen, P., Raisanen, M., and Johnson, R., 2009, Geochemical characterisation of seepage and drainage water quality from two sulphide mine tailings impoundments: Acid mine drainage versus neutral mine drainage: Mine Water and the Environment, v. 28, no. 1, p. 30-49, https://doi.org/10.1007/s10230-008-0056-2.","startPage":"30","endPage":"49","numberOfPages":"20","costCenters":[],"links":[{"id":244151,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216288,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10230-008-0056-2"}],"volume":"28","issue":"1","noUsgsAuthors":false,"publicationDate":"2008-11-30","publicationStatus":"PW","scienceBaseUri":"505a15ece4b0c8380cd54fb0","contributors":{"authors":[{"text":"Heikkinen, P.M.","contributorId":73435,"corporation":false,"usgs":true,"family":"Heikkinen","given":"P.M.","email":"","affiliations":[],"preferred":false,"id":452792,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Raisanen, M.L.","contributorId":96508,"corporation":false,"usgs":true,"family":"Raisanen","given":"M.L.","email":"","affiliations":[],"preferred":false,"id":452793,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johnson, R.H.","contributorId":7041,"corporation":false,"usgs":true,"family":"Johnson","given":"R.H.","email":"","affiliations":[],"preferred":false,"id":452791,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The amount of daily water-table rise (WTR) in the wells was summed at monthly and annual scales and estimates of specific yield (Sy) were used to convert the WTR to recharge. At the floodplain site, Sy was estimated from the ratio of WTR to total rainfall and in the uplands was based on the ratio of baseflow to WTR. In the floodplain, where the water table is shallow, recharge occurred throughout the year whenever precipitation occurred. In upland areas where the water table was deeper, WTR occurred in a stepped fashion and varied by season. Results indicated that the greatest amount of water-table rise over the 4-year period was observed in the floodplain (379 mm), followed by the upland (211 mm) and sideslopes (122 mm).

Ordinary least-squares and left-censored (Tobit) multiple-regression techniques were used to develop equations that relate these statistics, from continuous streamflow data at gaged locations with 10 or more years of record, to physical and climatic basin characteristics. Separate equations were developed to estimate these statistics for stations within similar hydrologic and geologic regions. Use of separate regressions by region substantially improved the accuracy of the estimate for streams in eastern and central Oklahoma when compared with estimating equations developed for the entire State, especially for regressions estimating lower flow duration values. For all regions, the equations were more reliable for estimating higher flow duration values. The accuracy of regressions for estimating flow duration statistics in western Oklahoma was very poor, especially for lower flow duration values. ?? 2009 ASCE.","largerWorkTitle":"Proceedings of World Environmental and Water Resources Congress 2009 - World Environmental and Water Resources Congress 2009: Great Rivers","conferenceTitle":"World Environmental and Water Resources Congress 2009: Great Rivers","conferenceDate":"17 May 2009 through 21 May 2009","conferenceLocation":"Kansas City, MO","language":"English","doi":"10.1061/41036(342)486","isbn":"9780784410363","usgsCitation":"Esralew, R., 2009, Development of regression models to estimate flow duration statistics at ungaged streams in Oklahoma using a regional approach, <i>in</i> Proceedings of World Environmental and Water Resources Congress 2009 - World Environmental and Water Resources Congress 2009: Great Rivers, v. 342, Kansas City, MO, 17 May 2009 through 21 May 2009, p. 4819-4831, https://doi.org/10.1061/41036(342)486.","startPage":"4819","endPage":"4831","numberOfPages":"13","costCenters":[],"links":[{"id":216084,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/41036(342)486"},{"id":243926,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"342","noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"505a0062e4b0c8380cd4f729","contributors":{"authors":[{"text":"Esralew, R.A.","contributorId":71030,"corporation":false,"usgs":true,"family":"Esralew","given":"R.A.","affiliations":[],"preferred":false,"id":452878,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The use of stable isotopes in such studies has several advantages over the use of radioisotopes, including cost, ease of handling, elimination of permit requirements, and waste disposal. A pilot study using brown trout was performed to evaluate sample preparation methods and the ability of a quadrupole inductively coupled plasma mass spectrometer (ICP-MS) system to successfully measure changes in the <sup>67</sup>Zn/<sup>66</sup>Zn ratios for planned exposure levels and duration. After completion of the pilot study, a full-scale zinc exposure study using rainbow trout was performed. The results of these studies indicate that there are several factors that affect the precision of the measured <sup>67</sup>Zn/<sup>66</sup>Zn ratios in the sample digests, including variations in sample size, endogenous zinc levels, and zinc uptake rates by individual fish. However, since these factors were incorporated in the calculation of the total zinc accumulated by the gills during the exposures, the data obtained were adequate for their intended use in calculating zinc binding and evaluating the influences of differences in water quality parameters.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Talanta","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.talanta.2009.07.048","issn":"00399140","usgsCitation":"Wolf, R., Todd, A., Brinkman, S., Lamothe, P.J., Smith, K., and Ranville, J., 2009, Measurement of total Zn and Zn isotope ratios by quadrupole ICP-MS for evaluation of Zn uptake in gills of brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss): Talanta, v. 80, no. 2, p. 676-684, https://doi.org/10.1016/j.talanta.2009.07.048.","startPage":"676","endPage":"684","numberOfPages":"9","costCenters":[],"links":[{"id":216114,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.talanta.2009.07.048"},{"id":243960,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"80","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5320e4b0c8380cd6c8bc","contributors":{"authors":[{"text":"Wolf, R.E.","contributorId":11827,"corporation":false,"usgs":true,"family":"Wolf","given":"R.E.","email":"","affiliations":[],"preferred":false,"id":452888,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Todd, A.S.","contributorId":53622,"corporation":false,"usgs":true,"family":"Todd","given":"A.S.","email":"","affiliations":[],"preferred":false,"id":452891,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brinkman, S.","contributorId":75781,"corporation":false,"usgs":true,"family":"Brinkman","given":"S.","email":"","affiliations":[],"preferred":false,"id":452893,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lamothe, P.

In addition to acute diseases causing severe morbidity and mortality, underlying chronic conditions that cause low-grade or subclinical infections may confound research results. Here we present recommendations and strategies to avoid or minimize the impacts of infectious agents in fishes maintained in the research setting. There are distinct differences in strategies for control of pathogens in fish used for research compared to fishes reared as pets or in aquaculture. Also, much can be learned from strategies and protocols for control of diseases in rodents used in research, but there are differences. This is due, in part, the unique aquatic environment that is modified by the source and quality of the water provided and the design of facilities. The process of control of pathogens and infectious diseases in fish research facilities is relatively new, and will be an evolving process over time. Nevertheless, the goal of documenting, detecting, and excluding pathogens in fish is just as important as in mammalian research models.<br data-mce-bogus=\"1\"></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.cbpc.2008.08.001","issn":"15320456","usgsCitation":"Kent, M., Feist, S., Harper, C., Hoogstraten-Miller, S., Law, J., Sanchez-Morgado, J.M., Tanguay, R., Sanders, G., Spitsbergen, J., and Whipps, C.M., 2009, Recommendations for control of pathogens and infectious diseases in fish research facilities: Comparative Biochemistry and Physiology, Part C: Toxicology & Pharmacology, v. 149, no. 2, p. 240-248, https://doi.org/10.1016/j.cbpc.2008.08.001.","productDescription":"9 p.","startPage":"240","endPage":"248","costCenters":[],"links":[{"id":476169,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://europepmc.org/articles/pmc3270489","text":"External Repository"},{"id":244056,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"149","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a968de4b0c8380cd8206f","contributors":{"authors":[{"text":"Kent, M.L.","contributorId":108058,"corporation":false,"usgs":true,"family":"Kent","given":"M.L.","email":"","affiliations":[],"preferred":false,"id":452927,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Feist, S.W.","contributorId":36382,"corporation":false,"usgs":true,"family":"Feist","given":"S.W.","email":"","affiliations":[],"preferred":false,"id":452921,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Harper, C.","contributorId":19380,"corporation":false,"usgs":true,"family":"Harper","given":"C.","email":"","affiliations":[],"preferred":false,"id":452918,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hoogstraten-Miller, S.","contributorId":100641,"corporation":false,"usgs":true,"family":"Hoogstraten-Miller","given":"S.","email":"","affiliations":[],"preferred":false,"id":452926,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Law, J.M.","contributorId":86995,"corporation":false,"usgs":true,"family":"Law","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":452924,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Sanchez-Morgado, J.

We used these data in a generalized mixed model of haul-out bout durations and a hierarchical Bayesian model of haul-out probabilities to assess factors related to walrus haul-out behavior, and provide the first predictive model of walrus haul-out behavior in sea ice habitat. Average haul-out bout duration was 9 h, but durations of haul-out bouts tended to increase with durations of preceding in-water bouts. On aver-age, tagged walruses spent only about 17% of their time hauled out on sea ice. Probability of being hauled out decreased with wind speed, increased with temperature, and followed a diurnal cycle with the highest values in the evening. Our haul-out probability model can be used to estimate the proportion of the population that is unavailable for detection in spring surveys of Pacific walruses on sea ice.","language":"English","publisher":"Candadian Science Publishing","doi":"10.1139/Z09-098","issn":"00084301","usgsCitation":"Udevitz, M.S., Jay, C.V., Fischbach, A., and Garlich-Miller, J., 2009, Modeling haul-out behavior of walruses in Bering Sea ice: Canadian Journal of Zoology, v. 87, no. 12, p. 1111-1128, https://doi.org/10.1139/Z09-098.","productDescription":"18 p.","startPage":"1111","endPage":"1128","numberOfPages":"18","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":244312,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"87","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5bfde4b0c8380cd6f964","contributors":{"authors":[{"text":"Udevitz, Mark S. 0000-0003-4659-138X mudevitz@usgs.gov","orcid":"https://orcid.org/0000-0003-4659-138X","contributorId":3189,"corporation":false,"usgs":true,"family":"Udevitz","given":"Mark","email":"mudevitz@usgs.gov","middleInitial":"S.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":453061,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jay, Chadwick V. 0000-0002-9559-2189 cjay@usgs.gov","orcid":"https://orcid.org/0000-0002-9559-2189","contributorId":192736,"corporation":false,"usgs":true,"family":"Jay","given":"Chadwick","email":"cjay@usgs.gov","middleInitial":"V.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":453059,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fischbach, Anthony S. 0000-0002-6555-865X afischbach@usgs.gov","orcid":"https://orcid.org/0000-0002-6555-865X","contributorId":200780,"corporation":false,"usgs":true,"family":"Fischbach","given":"Anthony S.","email":"afischbach@usgs.gov","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":453058,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Garlich-Miller, J.
