Growth of juvenile E. complanata mussels 10 months after exposure was also compared. Toxicity was determined after 12 h exposures at maximum concentrations from 2- to 2.5- fold higher than the LC99 for sea lamprey larvae. A logistic model was used to estimate the probability of survival among treatments, trials, species, and sizes. Mortality was minimal in all test concentrations of TFM alone and the TFM/1% niclosamide combination. Estimated survival decreased 6% for each unit increase in the relative toxicity of TFM. Survival was greater for E. complanata than for P. cataracta, and for adults relative to juveniles. Lampricide treatment caused narcotization of both mussels (defined as having gaped shells and an extended foot) in concentrations ??? LC99 for sea lamprey larvae and narcotization ranged from 0-50% among treatments. Recovery from narcosis was apparent by 12 h post-exposure and complete by 36 h post-exposure.

While Pescadero Creek (rural) experienced its flood of record, the adjacent San Lorenzo Creek (heavily populated), attained only its fourth-highest flow. This difference resulted from conditions present while the warm sector of the storm, with its associated low-level jet, high moisture content, and weak static stability, was overhead. Rainfall in the warm sector was dominated by orographic forcing. While the wind speed strongly modulated rain rates on windward slopes, the wind direction positioned the edge of a rain shadow cast by the Santa Lucia Mountains partially over the San Lorenzo basin, thus protecting the city of Santa Cruz from a more severe flood. Roughly 26% ?? 9% of the streamflow at flood peak on Pescadero Creek resulted from the warm-sector rainfall. Without this rainfall, the peak flow on Pescadero Creek would likely not have attained record status. These results are complemented by a climatological analysis based on ???50-yr-duration streamflow records for these and two other nearby windward watersheds situated ???20 to 40 km farther to the east, and a comparison of this climatological analysis with composites of NCEP-NCAR reanalysis fields. The westernmost watersheds were found to have their greatest floods during El Nin??o winters, while the easternmost watersheds peaked during non-El Nin??o episodes. These results are consistent with the case study, that showed that the composite 925-mb, meridionally oriented wind direction during El Nin??os favors a rain shadow over the eastern watersheds. During non-El Nin??o periods, the composite, zonally oriented wind direction indicates that the sheltering effect of the rain shadow on the eastern watersheds is reduced, while weaker winds, less water vapor, and stronger stratification reduce the peak runoff in the western watersheds relative to El Nin??o periods. These case study and climatological results illustrate the importance of conditions in the moisture-rich warm sector of landfalling Pacific winter storms. Although many other variables can influence flooding, this study shows that variations of ??10?? in wind direction can modulate the location of orographically enhanced floods. While terrain can increase predictability (e.g., rainfall typically increases with altitude), the predictability is reduced when conditions are near a threshold separating different regimes (e.g., in or out of a rain shadow ).","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrometeorology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1175/1525-7541(2003)004<1243:TIOAPR>2.0.CO;2","issn":"1525755X","usgsCitation":"Ralph, F., Neiman, P., Kingsmill, D., Persson, P., White, A., Strem, E., Andrews, E., and Antweiler, R.C., 2003, The impact of a prominent rain shadow on flooding in California's Santa Cruz Mountains: A CALJET case study and sensitivity to the ENSO cycle: Journal of Hydrometeorology, v. 4, no. 6, p. 1243-1264, https://doi.org/10.1175/1525-7541(2003)004<1243:TIOAPR>2.0.CO;2.","startPage":"1243","endPage":"1264","numberOfPages":"22","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":478504,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1175/1525-7541(2003)004<1243:tioapr>2.0.co;2","text":"Publisher Index Page"},{"id":235927,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209459,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1175/1525-7541(2003)004<1243:TIOAPR>2.0.CO;2"}],"volume":"4","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bacdde4b08c986b3237c6","contributors":{"authors":[{"text":"Ralph, F.M.","contributorId":39174,"corporation":false,"usgs":true,"family":"Ralph","given":"F.M.","email":"","affiliations":[],"preferred":false,"id":404711,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Neiman, P.J.","contributorId":14991,"corporation":false,"usgs":true,"family":"Neiman","given":"P.J.","email":"","affiliations":[],"preferred":false,"id":404708,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kingsmill, D.E.","contributorId":27658,"corporation":false,"usgs":true,"family":"Kingsmill","given":"D.E.","email":"","affiliations":[],"preferred":false,"id":404709,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Persson, P.O.G.","contributorId":58825,"corporation":false,"usgs":true,"family":"Persson","given":"P.O.G.","email":"","affiliations":[],"preferred":false,"id":404714,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"White, A.B.","contributorId":45878,"corporation":false,"usgs":true,"family":"White","given":"A.B.","email":"","affiliations":[],"preferred":false,"id":404712,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Strem, E.T.","contributorId":28420,"corporation":false,"usgs":true,"family":"Strem","given":"E.T.","email":"","affiliations":[],"preferred":false,"id":404710,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Andrews, E.D.","contributorId":13922,"corporation":false,"usgs":true,"family":"Andrews","given":"E.D.","email":"","affiliations":[],"preferred":false,"id":404707,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Antweiler, Ronald C. 0000-0001-5652-6034 antweil@usgs.gov","orcid":"https://orcid.org/0000-0001-5652-6034","contributorId":1481,"corporation":false,"usgs":true,"family":"Antweiler","given":"Ronald","email":"antweil@usgs.gov","middleInitial":"C.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":404713,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Recent data suggest that unionid mussels are sensitive to un-ionized ammonia (NH3) relative to other organisms. Existing sediment exposure systems are not suitable for ammonia toxicity studies with juvenile unionids; thus, we modified a system to expose juveniles to ammonia that was continuously infused into sediments. This system maintained consistent concentrations of ammonia in pore water up to 10 d. Juvenile <i>Lampsilis cardium</i> mussels were exposed to NH<sub>3<sub> in pore water in replicate 96-h and 10-d sediment toxicity tests. The 96-h median lethal concentrations (LC50s) were 127 and 165 &mu;g NH<sub>3</sub>-N/L, and the 10-d LC50s were 93 and 140 &mu;g NH<sub>3</sub>-N/L. The median effective concentrations (EC50s) (based on the proportion affected, including dead and inactive mussels) were 73 and 119 &mu;g NH<sub>3</sub>-N/L in the 96-h tests and 71 and 99 &mu;g NH<sub>3</sub>-N/L in the 10-d tests. Growth rate was substantially reduced at concentrations between 31 and 76 &mu;g NH<sub>3</sub>-N/L.

The method is based on comparisons between X-ray diffraction (XRD) patterns of K-saturated, ethylene glycol-solvated, oriented samples and calculated XRD patterns for three-component, mixed-layer systems. For the calculated patterns it is assumed that the measured patterns can be modeled as random interstratifications of fully expanding 17.1 Å layers, partially expanding 13.5 Å layers and non-expanding 9.98 Å layers. The technique was tested using 29 well characterized smectites. According to their XRD patterns, smectites were classified as group 1 (low-charge smectites) and group 2 (high-charge smectites). The boundary between the two groups is at a layer charge of −0.46 equivalents per half unit-cell. Low-charge smectites are dominated by 17.1 Å layers, whereas high-charge smectites contain only 20% fully expandable layers on average.

Considering the prevailing cryogenic climates and the abundance of salts and iron minerals on Mars, any attempt at comprehensive modeling of Martian aqueous chemistry should include iron chemistry and be valid at low temperatures and high solution concentrations. The objectives of this paper were to (1) estimate ferrous iron Pitzer-equation parameters and iron mineral solubility products at low temperatures (from < 0 ??C to 25 ??C), (2) incorporate these parameters and solubility products into the FREZCHEM model, and (3) use the model to simulate the surficial aqueous geochemical evolution of Mars. Ferrous iron Pitzer-equation parameters were derived in this work or taken from the literature. Six new iron minerals [FeCl2??4H2O, FeCl2??6H2O, FeSO4??H2O, FeSO4??7H2O, FeCO3, and Fe(OH)3] were added to the FREZCHEM model bringing the total solid phases to 56. Agreement between model predictions and experimental data are fair to excellent for the ferrous systems: Fe-Cl, Fe-SO4, Fe-HCO3, H-Fe-Cl, and H-Fe-SO4. We quantified a conceptual model for the aqueous geochemical evolution of the Martian surface. The five stages of the conceptual model are: (1) carbonic acid weathering of primary ferromagnesian minerals to form an initial magnesium-iron-bicarbonate-rich solution; (2) evaporation and precipitation of carbonates, including siderite (FeCO3), with evolution of the brine to a concentrated NaCl solution; (3) ferrous/ferric iron oxidation; (4) either evaporation or freezing of the brine to dryness; and (5) surface acidification. What began as a dilute Mg-Fe-HCO3 dominated leachate representing ferromagnesian weathering evolved into an Earth-like seawater composition dominated by NaCl, and finally into a hypersaline Mg-Na-SO4-Cl brine. Weathering appears to have taken place initially under conditions that allowed solution of ferrous iron [low O2(g)], but later caused oxidation of iron [high O2(g)]. Surface acidification and/or sediment burial can account for the minor amounts of Martian surface carbonates. This model rests on a large number of assumptions and is therefore speculative. Nevertheless, the model is consistent with current understanding concerning surficial salts and minerals based on Martian meteorites, Mars lander data, and remotely-sensed spectral analyses. ?? 2003 Elsevier Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochimica et Cosmochimica Acta","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0016-7037(03)00372-7","issn":"00167037","usgsCitation":"Marion, G., Catling, D., and Kargel, J., 2003, Modeling aqueous ferrous iron chemistry at low temperatures with application to Mars: Geochimica et Cosmochimica Acta, v. 67, no. 22, p. 4251-4266, https://doi.org/10.1016/S0016-7037(03)00372-7.","startPage":"4251","endPage":"4266","numberOfPages":"16","costCenters":[],"links":[{"id":209358,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0016-7037(03)00372-7"},{"id":235694,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"67","issue":"22","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5bdee4b0c8380cd6f872","contributors":{"authors":[{"text":"Marion, G.M.","contributorId":44691,"corporation":false,"usgs":true,"family":"Marion","given":"G.M.","email":"","affiliations":[],"preferred":false,"id":404654,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Catling, D.C.","contributorId":78135,"corporation":false,"usgs":true,"family":"Catling","given":"D.C.","email":"","affiliations":[],"preferred":false,"id":404655,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kargel, J.S.","contributorId":88096,"corporation":false,"usgs":true,"family":"Kargel","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":404656,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We conducted a series of experiments using Berea sandstone samples to examine the physical mechanisms controlling flow in a rock containing a single isolated fracture. The input fluxes and fracture orientation were varied in these experiments. Visualization experiments using dyed water in a thin vertical slab of rock were conducted to identify flow mechanisms occurring due to the presence of the isolated fracture. Two mechanisms occurred: (1) localized flow through the rock matrix in the vicinity of the isolated fracture and (2) pooling of water at the bottom of the fracture, indicating the occurrence of film flow along the isolated fracture wall. These mechanisms were observed at fracture angles of 20 and 60 degrees from the horizontal, but not at 90 degrees. Pooling along the bottom of the fracture was observed over a wider range of input fluxes for low‐angled isolated fractures compared to high‐angled ones. Measurements of matrix water pressures in the samples with the 20 and 60 degree fractures also demonstrated that preferential flow occurred through the matrix in the fracture vicinity, where higher pressures occurred in the regions where faster flow was observed in the visualization experiments. The pooling length at the terminus of a 20 degree isolated fracture was measured as a function of input flux. Calculations of the film flow rate along the fracture were made using these measurements and indicated that up to 22% of the flow occurred as film flow. These experiments, apparently the first to consider isolated fractures, demonstrate that such features can accelerate flow through the unsaturated zone and should be considered when developing conceptual models.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2002WR001691","usgsCitation":"Su, G.W., Nimmo, J.R., and Dragila, M.I., 2003, Effect of isolated fractures on accelerated flow in unsaturated porous rock: Water Resources Research, v. 39, no. 12, p. 1-1-1-5, https://doi.org/10.1029/2002WR001691.","productDescription":"Article 1326; 5 p.","startPage":"1-1","endPage":"1-5","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":478538,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2002wr001691","text":"Publisher Index Page"},{"id":235693,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"39","issue":"12","noUsgsAuthors":false,"publicationDate":"2003-12-02","publicationStatus":"PW","scienceBaseUri":"505a05f0e4b0c8380cd51033","contributors":{"authors":[{"text":"Su, Grace W.","contributorId":145734,"corporation":false,"usgs":false,"family":"Su","given":"Grace","email":"","middleInitial":"W.","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":404652,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nimmo, John R. 0000-0001-8191-1727 jrnimmo@usgs.gov","orcid":"https://orcid.org/0000-0001-8191-1727","contributorId":757,"corporation":false,"usgs":true,"family":"Nimmo","given":"John","email":"jrnimmo@usgs.gov","middleInitial":"R.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":404653,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dragila, Maria I.","contributorId":8657,"corporation":false,"usgs":false,"family":"Dragila","given":"Maria","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":404651,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

They are arrayed radially across an 800 km wide structural dome, with the oldest at the crest and the youngest around the flanks. Several lines of evidence suggest that these rocks evolved via opensystem,&nbsp;</span>polybaric<span>&nbsp;fractionation. We have used mass balance modeling of major elements together with trace-element data and mineral chemistry to help explain the&nbsp;</span>evolution<span>&nbsp;of this diverse suite of felsic rocks, which appear to have been generated coevally&nbsp;</span>in<span>&nbsp;isolated magma chambers, and erupted close to each other&nbsp;</span>in<span>&nbsp;patterns related to tectonic uplift and extension within the West Antarctic rift system. Isotopic and trace-element data indicate that this occurred with only minimal crustal contamination. We focus on&nbsp;</span>volcanoes<span>&nbsp;of the Executive Committee Range and Mount Murphy, where we find good representation of basalts and felsic rocks within a small area. Our results suggest that the felsic rocks were derived from basaltic magmas that differentiated at multiple levels during their passage to the surface: first to ferrogabbroic compositions near the base of the lithosphere, then to intermediate compositions near the base of the crust, and finally to felsic compositions&nbsp;</span>in<span>&nbsp;mid- to upper crustal reservoirs.

Development of&nbsp;</span>peralkalinity<span>&nbsp;</span>in<span>&nbsp;felsic rocks took place&nbsp;</span>in<span>&nbsp;upper crustal reservoirs by fractionating a high ratio of plagioclase to clinopyroxene under conditions of low pH</span><sub>2</sub><span>O.

The volume and diversity of felsic rocks were probably enhanced by the structure of the lithosphere, the persistence of plume activity, and the immobility of the Antarctic plate. Mechanical boundaries at the base of the lithosphere and crust, and within the crust, appear to have acted as filters, trapping magmas at multiple levels, and prolonging the fractionation process. Final volumes would have been further enhanced by repeated refluxing of the same magma chambers, controlled by plume activity and plate immobility.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.2747/0020-6814.45.12.1055","issn":"00206814","usgsCitation":"LeMasurier, W., Futa, K., Hole, M., and Kawachi, Y., 2003, Polybaric evolution of phonolite, trachyte, and rhyolite volcanoes in eastern Marie Byrd Land, Antarctica: Controls on peralkalinity and silica saturation: International Geology Review, v. 45, no. 12, p. 1055-1099, https://doi.org/10.2747/0020-6814.45.12.1055.","productDescription":"45 p.","startPage":"1055","endPage":"1099","costCenters":[],"links":[{"id":387742,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Antarctica","volume":"45","issue":"12","noUsgsAuthors":false,"publicationDate":"2010-07-14","publicationStatus":"PW","scienceBaseUri":"505a7ce6e4b0c8380cd79c3d","contributors":{"authors":[{"text":"LeMasurier, W.E.","contributorId":7006,"corporation":false,"usgs":true,"family":"LeMasurier","given":"W.E.","email":"","affiliations":[],"preferred":false,"id":404647,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Futa, K.","contributorId":26435,"corporation":false,"usgs":true,"family":"Futa","given":"K.","affiliations":[],"preferred":false,"id":404648,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hole, M.","contributorId":80876,"corporation":false,"usgs":true,"family":"Hole","given":"M.","email":"","affiliations":[],"preferred":false,"id":404650,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kawachi, Y.","contributorId":45875,"corporation":false,"usgs":true,"family":"Kawachi","given":"Y.","email":"","affiliations":[],"preferred":false,"id":404649,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

This nutrient supply plays a critical biological feedback role in salmon sustainability by supporting juvenile salmon production. We first demonstrate how nutrient feedback potential to juvenile production may be unaccounted for in spawner-recruit models of populations under long-term exploitation. We then present a heuristic, life history-based, spreadsheet survival model that incorporates salmon carcass-driven nutrient feedback to the freshwater components of the salmon ecosystem. The productivity of a hypothetical coho salmon population was simulated using rates from the literature for survival from spawner to egg, egg to fry, fry to smolt, and smolt to adult. The effects of climate variation and nutrient feedback on survival were incorporated, as were density-dependent effects of the numbers of spawners and fry on freshwater survival of eggs and juveniles. The unexploited equilibrium population was subjected to 100 years of 20, 40, 60, and 80% harvest. Each harvest scenario greater than 20% brought the population to a reduced steady state, regardless of generous compensatory survival at low population sizes. Increasing harvest reduced the positive effects of nutrient contributions to population growth. Salmon researchers should further explore this modeling approach for establishing escapement goals. Given the importance of nutrient feedback, managers should strive for generous escapements that support nutrient rebuilding, as well as egg deposition, to ensure strong future salmon production.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Fisheries Society Symposium","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"08922284","usgsCitation":"Knudsen, E., Symmes, E., and Margraf, F., 2003, Searching for a life history approach to salmon escapement management: American Fisheries Society Symposium, v. 2003, no. 34, p. 261-276.","startPage":"261","endPage":"276","numberOfPages":"16","costCenters":[],"links":[{"id":235733,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2003","issue":"34","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8853e4b08c986b3168f7","contributors":{"authors":[{"text":"Knudsen, E.E.","contributorId":26116,"corporation":false,"usgs":true,"family":"Knudsen","given":"E.E.","email":"","affiliations":[],"preferred":false,"id":404486,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Symmes, E.W.","contributorId":45095,"corporation":false,"usgs":true,"family":"Symmes","given":"E.W.","email":"","affiliations":[],"preferred":false,"id":404487,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Margraf, F.J.","contributorId":47738,"corporation":false,"usgs":true,"family":"Margraf","given":"F.J.","email":"","affiliations":[],"preferred":false,"id":404488,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

This is a powerful approach that is broadly applicable but underutilized in conservation biology. We applied the approach to a population recovery analysis of threatened and endangered piping plovers (Charadrius melodus) in the Great Plains of North America. Predator exclusion increases the reproductive success of piping plovers, but the most cost-efficient strategy of applying predator exclusion and the number of protected breeding pairs necessary to prevent further population declines were unknown. We developed a linear programming model to define strategies that would either maximize fledging rates or minimize financial costs by allocating plover pairs to 1 of 6 types of protection. We evaluated the optimal strategies using a stochastic population simulation model. The minimum cost to achieve a 20% chance of stabilizing simulated populations was approximately $1-11 million over 50 years. Increasing reproductive success to 1.24 fledglings/pair at minimal cost in any given area required fencing 85% of pairs at managed sites but cost 23% less than the current approach. Maximum fledging rates resulted in >20% of simulated populations reaching recovery goals in 30-50 years at cumulative costs of <$16 million. Protecting plover pairs within 50 km of natural resource agency field offices was sufficient to increase simulated populations to established recovery goals. A range-wide management plan needs to be developed and implemented to foster the involvement and cooperation among managers that will be necessary for recovery efforts to be successful. We also discuss how our approach can be applied to a variety of wildlife management issues.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wildlife Society Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00917648","usgsCitation":"Larson, M., Ryan, M., and Murphy, R., 2003, Assessing recovery feasibility for piping plovers using optimization and simulation: Wildlife Society Bulletin, v. 31, no. 4, p. 1105-1116.","startPage":"1105","endPage":"1116","numberOfPages":"12","costCenters":[],"links":[{"id":236144,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eddfe4b0c8380cd49a7c","contributors":{"authors":[{"text":"Larson, M.A.","contributorId":15814,"corporation":false,"usgs":true,"family":"Larson","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":404416,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ryan, M.R.","contributorId":92198,"corporation":false,"usgs":true,"family":"Ryan","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":404418,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Murphy, R.K.","contributorId":48910,"corporation":false,"usgs":true,"family":"Murphy","given":"R.K.","email":"","affiliations":[],"preferred":false,"id":404417,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

To learn more about factors affecting hydrologic retention, we repeated stream-tracer injections for 5 years in a semi-arid alluvial stream (Pinal Creek, Ariz.) during a period when streamflow was decreasing, channel width increasing, and coverage of aquatic macrophytes expanding. Average stream velocity at Pinal Creek decreased from 0.8 to 0.2 m/s, average stream depth decreased from 0.09 to 0.04 m, and average channel width expanded from 3 to 13 m. Modeling of tracer experiments indicated that the hydrologic retention factor (<i>R</i><sub>h</sub>), a measure of the average time that solute spends in storage per unit length of downstream transport, increased from 0.02 to 8 s/m. At the same time the ratio of cross-sectional area of storage zones to main channel cross-sectional area (<i>A</i><sub>s</sub>/<i>A</i>) increased from 0.2 to 0.8 m<sup>2</sup>/m<sup>2</sup>, and average water residence time in storage zones (<i>t</i><sub>s</sub>) increased from 5 to 24 min. Compared with published data from four other streams in the US, Pinal Creek experienced the greatest change in hydrologic retention for a given change in streamflow. The other streams differed from Pinal Creek in that they experienced a change in streamflow between tracer experiments without substantial geomorphic or vegetative adjustments. As a result, a regression of hydrologic retention on streamflow developed for the other streams underpredicted the measured increases in hydrologic retention at Pinal Creek. The increase in hydrologic retention at Pinal Creek was more accurately predicted when measurements of the Darcy–Weisbach friction factor were used (either alone or in addition to streamflow) as a predictor variable. We conclude that relatively simple measurements of channel friction are useful for predicting the response of hydrologic retention in streams to major adjustments in channel morphology as well as changes in streamflow.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/S0309-1708(03)00085-X","issn":"03091708","usgsCitation":"Harvey, J., Conklin, M., and Koelsch, R., 2003, Predicting changes in hydrologic retention in an evolving semi-arid alluvial stream: Advances in Water Resources, v. 26, no. 9, p. 939-950, https://doi.org/10.1016/S0309-1708(03)00085-X.","productDescription":"12 p.","startPage":"939","endPage":"950","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":236065,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209517,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0309-1708(03)00085-X"}],"volume":"26","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a81aee4b0c8380cd7b68b","contributors":{"authors":[{"text":"Harvey, J.

Four decision criteria were used to estimate effects, including amount of area, length of edge, lowest number of contiguous reserves, and greatest number of terrestrial vertebrate species covered. A fifth evaluation criterion was the effect each sampling scheme had on the ability of the modeled conservation reserves to cover the six major ecoregions found in Utah. Of the three sampling schemes, county boundaries covered the greatest number of species, but also created the longest length of edge and greatest number of reserves. Watersheds maximized species coverage using the least amount of area. Hexagons and watersheds provide the least amount of edge and fewest number of reserves.

An additional purpose was to determine if and how this inner shelf seaward of a major estuary differed from the inner shelves located just to the north and south but seaward of barrier-island shorelines. Through side-scan sonar mosaicking, bathymetric studies, and ground-truthing using surface grab samples as well as diver observations, two large submarine sand plains were mapped - one being the modern ebb-tidal delta and the other interpreted to be a relict ebb-tidal delta formed earlier in the Holocene. The most seaward portion of the inner shelf studied consists of a field of lobate, bathymetrically elevated, fine-sand accumulations, which were interpreted to be sediment-starved 3D dunes surrounded by small 2D dunes composed of coarse molluscan shell gravel. Additionally, exposed limestone hardbottoms supporting living benthic communities were found as well. This modern shelf sedimentary environment is situated on a large, buried shelf valley, which extends eastward beneath the modern Tampa Bay estuary. These observations plus the absence of an incised shelf valley having surficial bathymetric expression, and the absence of sand bodies normally associated with back-tracking estuarine systems indicate that there was no cross-shelf estuarine retreat path formed during the last rise in sea level. Instead, the modern Tampa Bay formed within a mid-platform, low-relief depression, which was flooded by rising marine waters late in the Holocene. With continued sea-level rise in the late Holocene, this early embayment was translated eastward or landward to its present position, whereby a larger ebb-tidal delta prograded out onto the inner shelf. Extensive linear sand ridges, common to the inner shelves to the north and south, did not form in this shelf province because it was a low-energy, open embayment lacking the wave climate and nearshore zone necessary to create such sand bodies. The distribution of bedforms on the inner shelf and the absence of seaward-oriented 2D dunes on the modern ebb-tidal delta indicate that the modern estuarine system has had little effect on its adjacent inner shelf. ?? 2003 Elsevier B.V.

To fit the observed uplift we calculate synthetic postseismic deformation using the relaxation response of a gravitational viscoelastic Earth to the earthquake. For a model with an elastic plate overlying a viscoelastic half-space, we find that the elastic thickness is 38 ?? 8 km, which isclose to the local crustal thickness. The half-space viscosity is estimated at 4 ?? 1018??0.5 Pa s. The leveling data do not require a viscous lower crust but permit a lower bound viscosity of 1020 Pa s. The observed broad uplift cannot be explained by physically plausible afterslip on and below the coseismic fault. However, local deformation across the coseismic surface rupture requires shallow afterslip reaching the surface. The postseismic deformation induced by the estimated viscoelastic structure decays exponentially with a time constant of ???15 years. Because of coupling between the elastic layer and the viscoelastic substrate, this relaxation time is significantly longer than the 2 year Maxwell relaxation time of the viscous half-space itself. Our result suggests the importance of postseismic relaxation in interpreting high-precision global positioning system velocities. For example, our model results suggest that postseismic transient velocities from both the 1959 Hebgen Lake and the 1983 Mw = 6.9 Borah Peak earthquakes are currently as large as 1-2 mm/yr.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research B: Solid Earth","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"01480227","usgsCitation":"Nishimura, T., and Thatcher, W., 2003, Rheology of the lithosphere inferred from postseismic uplift following the 1959 Hebgen Lake earthquake: Journal of Geophysical Research B: Solid Earth, v. 108, no. 8.","costCenters":[],"links":[{"id":235993,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"108","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aad3ee4b0c8380cd86e7a","contributors":{"authors":[{"text":"Nishimura, T.","contributorId":94834,"corporation":false,"usgs":true,"family":"Nishimura","given":"T.","email":"","affiliations":[],"preferred":false,"id":404394,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thatcher, W.","contributorId":32669,"corporation":false,"usgs":true,"family":"Thatcher","given":"W.","email":"","affiliations":[],"preferred":false,"id":404393,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Besides this summary paper, a companion CD-ROM with more extensive discussion, figures, tables, and raw data is available to the interested researcher from the GEWEX project office, the GAPP project office, or the first author. An updated online version of the CD-ROM is also available at http://ecpc.ucsd.edu/gcip/webs.htm/. Observations cannot adequately characterize or \"close\" budgets since too many fundamental processes are missing. Models that properly represent the many complicated atmospheric and near-surface interactions are also required. This preliminary synthesis therefore included a representative global general circulation model, regional climate model, and a macroscale hydrologic model as well as a global reanalysis and a regional analysis. By the qualitative agreement among the models and available observations, it did appear that we now qualitatively understand water and energy budgets of the Mississippi River Basin. However, there is still much quantitative uncertainty. In that regard, there did appear to be a clear advantage to using a regional analysis over a global analysis or a regional simulation over a global simulation to describe the Mississippi River Basin water and energy budgets. There also appeared to be some advantage to using a macroscale hydrologic model for at least the surface water budgets.

Because of potential ecological effects, dissolved zinc and orthophosphate were the solutes of primary interest. Results from deployments of an in situ flux chamber indicated that benthic fluxes of dissolved Zn and orthophosphate were comparable in magnitude to riverine inputs. Tracer analyses and benthic-community metrics provided evidence that solute benthic flux were diffusion-controlled at the flux-chamber deployment sites. That is, effects of biomixing (or bioturbation) and ground-water interactions did not strongly influence benthic flux. Remediation efforts in the river might not produce desired water-quality effects in the lake because imposed shifts in concentration gradients near the sediment-water interface would generate a benthic feedback response. Therefore, development of water-quality models to justify remediation strategies requires consideration of contaminant flux between the water column and underlying sediment in basins that have been affected by long-term (decadal) anthropogenic activities.","language":"English","publisher":"Springer","doi":"10.1007/s00267-003-0020-7","issn":"0364152X","usgsCitation":"Kuwabara, J., Carter, J., Topping, B., Fend, S., Woods, P.F., Berelson, W., and Balistrieri, L.S., 2003, Importance of Sediment-Water Interactions in Coeur d'Alene Lake, Idaho, USA: Management Implications: Environmental Management, v. 32, no. 3, p. 348-359, https://doi.org/10.1007/s00267-003-0020-7.","productDescription":"12 p.","startPage":"348","endPage":"359","costCenters":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true},{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":235886,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209440,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00267-003-0020-7"}],"country":"United States","state":"Idaho","otherGeospatial":"Coeur d’Alene Lake","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117,\n              47.25\n            ],\n            [\n              -115.5,\n              47.25\n            ],\n            [\n              -115.5,\n              47.75\n            ],\n            [\n              -117,\n              47.75\n            ],\n            [\n              -117,\n              47.25\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"32","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3932e4b0c8380cd6183c","contributors":{"authors":[{"text":"Kuwabara, J.S.","contributorId":57905,"corporation":false,"usgs":true,"family":"Kuwabara","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":404345,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Carter, J.L.","contributorId":26030,"corporation":false,"usgs":true,"family":"Carter","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":404342,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Topping, B.R.","contributorId":97541,"corporation":false,"usgs":true,"family":"Topping","given":"B.R.","email":"","affiliations":[],"preferred":false,"id":404347,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"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":404348,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Woods, P.

To monitor harvest levels in the Pacific Flyway, biologists commonly use culmen length and plumage color to differentiate among subspecies on sympatric wintering grounds. Among the four large-bodied Pacific subspecies (</span><i>B. c. parvipes</i><span>, </span><i>B. c. occidentalis</i><span>, </span><i>B. c. fulva</i><span>, and </span><i>B. c. moffitti</i><span>), overlap in culmen length and subjectivity of visually assessing color results in misclassification and inaccurate harvest estimates. We examined the morphology of Pacific large-bodied Canada Geese to characterize body size variation among subspecies and provide more discriminatory measures for harvest assessments. We found that culmen length, one of the most commonly used field measures, overlapped widely among subspecies, and it had little support for inclusion in discriminatory models. Morphological measures with greater explanatory power included bill width at nail, bill width at base, head length, and mid wing. If culmen length and plumage color continue to be used to assess winter harvest, we recommend the addition of at least one sex-specific measurement to reduce levels of misclassification among subspecies. If an additional morphological measure is included, further evaluation on the wintering grounds should be conducted as this measure's effectiveness may vary depending upon observer bias, temporal and spatial variation in subspecies abundance, and the proportion of birds accurately sexed by cloacal examination.</span></p>","language":"English","publisher":"Wiley","doi":"10.1648/0273-8570-74.4.357","issn":"02738570","usgsCitation":"Pearce, J.M., and Bollinger, K.S., 2003, Morphological traits of Pacific Flyway Canada Geese as an aid to subspecies identification and management: Journal of Field Ornithology, v. 74, no. 4, p. 357-369, https://doi.org/10.1648/0273-8570-74.4.357.","productDescription":"13 p.","startPage":"357","endPage":"369","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"links":[{"id":235773,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","otherGeospatial":"Pacific Flyway","volume":"74","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5e43e4b0c8380cd708f4","contributors":{"authors":[{"text":"Pearce, John M. 0000-0002-8503-5485 jpearce@usgs.gov","orcid":"https://orcid.org/0000-0002-8503-5485","contributorId":181766,"corporation":false,"usgs":true,"family":"Pearce","given":"John","email":"jpearce@usgs.gov","middleInitial":"M.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":404315,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bollinger, Karen S.","contributorId":33842,"corporation":false,"usgs":true,"family":"Bollinger","given":"Karen","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":404314,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This approach is a simple, spreadsheet-based implementation of existing models that can be used for analysis of tests from confined or unconfined aquifers. Field examples of tests exhibiting oscillatory and nonoscillatory behavior are used to illustrate the procedure and to compare results with estimates obtained using alternative approaches. The procedure is considerably simpler than recently proposed methods for this hydrogeologic setting. Although the simplifications required by the approach can introduce error into hydraulic-conductivity estimates, this additional error becomes negligible when appropriate measures are taken in the field. These measures are summarized in a set of practical field guidelines for slug tests in highly permeable aquifers.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ground Water","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1745-6584.2003.tb02400.x","issn":"0017467X","usgsCitation":"Butler, J., Garnett, E., and Healey, J., 2003, Analysis of Slug Tests in Formations of High Hydraulic Conductivity: Ground Water, v. 41, no. 5, p. 620-630, https://doi.org/10.1111/j.1745-6584.2003.tb02400.x.","startPage":"620","endPage":"630","numberOfPages":"11","costCenters":[],"links":[{"id":209389,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6584.2003.tb02400.x"},{"id":235771,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"41","issue":"5","noUsgsAuthors":false,"publicationDate":"2005-12-13","publicationStatus":"PW","scienceBaseUri":"5059eb00e4b0c8380cd48b4e","contributors":{"authors":[{"text":"Butler, J.J.

A similar collar design has been used on caribou (Rangifer tarandus), but we found that the collar did not expand quickly enough to accommodate increase in neck circumference of fawns during the first 2 months of life. Consequently, we modified the stitching pattern so that the first expansion fold opened faster. We monitored performance of this modification on free-ranging and captive fawns. Also, we collected data on neck growth in fawns to document design requirements of expandable collars for white-tailed deer. Mean neck circumference at ???14 days of age of free-ranging fawns in Pennsylvania was 17.8 cm (SD=1.67, n=62) for males and 17.3 cm (SD=1.50, n=52) for females. Based on measurements of captive fawns, neck circumference increased 8.8 cm from birth to August, 2.5 cm from August to October, and 2.6 cm from October to March. Observations of captive fawns fitted with dummy radiocollars indicated that collars expanded when needed and caused no apparent discomfort to fawns. We detected no problems with use of 86 collars on 113 free-ranging fawns for >270 days and recovered radiocollars expanded as designed. The elastic collar material failed on 3 collars (3%) after 142, 207, and 226 days on fawns, and 1-5 radiocollars (???4%) were cast by fawns. Our modification to this radiocollar design reduced fawn discomfort or suffering, allowing researchers to better comply with principles of the Animal Welfare Act.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wildlife Society Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00917648","usgsCitation":"Diefenbach, D., Kochanny, C., Vreeland, J., and Wallingford, B., 2003, Evaluation of an expandable, breakaway radiocollar for white-tailed deer fawns: Wildlife Society Bulletin, v. 31, no. 3, p. 756-761.","startPage":"756","endPage":"761","numberOfPages":"6","costCenters":[],"links":[{"id":235729,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0c45e4b0c8380cd52adf","contributors":{"authors":[{"text":"Diefenbach, Duane R. 0000-0001-5111-1147","orcid":"https://orcid.org/0000-0001-5111-1147","contributorId":106592,"corporation":false,"usgs":true,"family":"Diefenbach","given":"Duane R.","affiliations":[],"preferred":false,"id":404299,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kochanny, C.O.","contributorId":79437,"corporation":false,"usgs":true,"family":"Kochanny","given":"C.O.","email":"","affiliations":[],"preferred":false,"id":404298,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Vreeland, J.K.","contributorId":22528,"corporation":false,"usgs":true,"family":"Vreeland","given":"J.K.","email":"","affiliations":[],"preferred":false,"id":404296,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wallingford, B.D.","contributorId":62726,"corporation":false,"usgs":true,"family":"Wallingford","given":"B.D.","email":"","affiliations":[],"preferred":false,"id":404297,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

One Pb&nbsp;</span>source<span>&nbsp;dominates the ore stage. It has a limited Pb isotope range characterized by&nbsp;</span><sup>208</sup><span>Pb/&nbsp;</span><sup>206</sup><span>Pb values of 2.000 to 2.005 and&nbsp;</span><sup>207</sup><span>Pb/&nbsp;</span><sup>206</sup><span>Pb values of 0.8031 to 0.8075, as recorded by 10-μm-diameter spot SHRIMP analyses of ore-stage arsenian pyrite. These values approximately correspond to&nbsp;</span><sup>206</sup><span>Pb/&nbsp;</span><sup>204</sup><span>Pb of 19.3 to 19.6,&nbsp;</span><sup>207</sup><span>Pb/&nbsp;</span><sup>204</sup><span>Pb of 15.65 to 15.75, and&nbsp;</span><sup>208</sup><span>Pb/&nbsp;</span><sup>204</sup><span>Pb of 39.2 to 39.5. This Pb&nbsp;</span>source<span>&nbsp;is isotopically similar to that&nbsp;</span>in<span>&nbsp;average Neoproterozoic and Cambrian elastic rocks but not to any&nbsp;</span>potential<span>&nbsp;magmatic&nbsp;</span>sources<span>. Whether those clastic rocks provided Pb to the ore&nbsp;</span>fluid<span>&nbsp;cannot be unequivocally proven because their Pb isotope compositions over the same range as&nbsp;</span>in<span>&nbsp;ore-stage arsenian pyrite are similar to those of Ordovician to Devonian siliciclastic and calcareous rocks. The Pb&nbsp;</span>source<span>&nbsp;</span>in<span>&nbsp;the calcareous rocks most likely is largely detrital minerals, since that detritus was derived from the same&nbsp;</span>sources<span>&nbsp;as the detritus&nbsp;</span>in<span>&nbsp;the Neoproterozoic and Cambrian clastic rocks. The second Pb&nbsp;</span>source<span>&nbsp;is characterized by a large range of&nbsp;</span><sup>206</sup><span>Pb/&nbsp;</span><sup>204</sup><span>Pb values (18-34) with a limited range of&nbsp;</span><sup>208</sup><span>Pb/&nbsp;</span><sup>204</sup><span>Pb values (38.1-39.5), indicating low but variable Th/U and high and variable U/Pb values. The second Pb&nbsp;</span>source<span>&nbsp;dominates late and postore-stage minerals but is also found&nbsp;</span>in<span>&nbsp;preore sulfide minerals. These Pb isotope characteristics typify Ordovician to Devonian siliciclastic and calcareous rocks around the&nbsp;</span>Carlin<span>&nbsp;trend&nbsp;</span>in<span>&nbsp;northeast&nbsp;</span>Nevada<span>. Petrologically similar rocks host the&nbsp;</span>Getchell<span>&nbsp;and&nbsp;</span>Turquoise<span>&nbsp;</span>Ridge<span>&nbsp;</span>deposits<span>.&nbsp;</span>Lead<span>&nbsp;from the second&nbsp;</span>source<span>&nbsp;was either contributed from the host&nbsp;</span>sedimentary<span>&nbsp;</span>rock<span>&nbsp;sequences or brought into the hydrothermal system by oxidized ground water as the system collapsed. Late ore- and postore-stage sulfide minerals (pyrite, orpiment, and stibnite) from the Betze-Post and Meikle&nbsp;</span>deposits<span>&nbsp;</span>in<span>&nbsp;the&nbsp;</span>Carlin<span>&nbsp;trend and from the Jerritt Canyon mining district have Pb isotope characteristics similar to those determined&nbsp;</span>in<span>&nbsp;</span>Getchell<span>&nbsp;and&nbsp;</span>Turquoise<span>&nbsp;</span>Ridge<span>. This observation suggests that the Pb isotope compositions of their ore fluids may be similar to those at&nbsp;</span>Getchell<span>&nbsp;and&nbsp;</span>Turquoise<span>&nbsp;</span>Ridge<span>. Two models can explain the Pb isotope compositions of the ore-stage arsenian pyrite versus the late ore or postore sulfide minerals.&nbsp;</span>In<span>&nbsp;either model, Pb from the Ordovician to Devonian siliciclastic and calcareous&nbsp;</span>rock<span>&nbsp;</span>source<span>&nbsp;enters the hydrothermal system late&nbsp;</span>in<span>&nbsp;the ore stage but not to any extent during the main stage of ore deposition.&nbsp;</span>In<span>&nbsp;one model, ore-stage Pb was derived from a&nbsp;</span>source<span>&nbsp;with Pb isotope compositions similar to those of the Neoproterozoic and Cambrian clastic sequence, transported as part of the ore&nbsp;</span>fluid<span>&nbsp;and then deposited&nbsp;</span>in<span>&nbsp;the ore-stage arsenian pyrite and fluorite. The second model is based on the observation that the Pb isotope characteristics of the ore-stage minerals also are found&nbsp;</span>in<span>&nbsp;some Ordovician to Devonian calcareous and siliciclastic rocks. Hence, ore-stage Pb could have been derived locally and simply concentrated during the ore stage. Critical to the second model is the removal of all high&nbsp;</span><sup>206</sup><span>Pb/&nbsp;</span><sup>204</sup><span>Pb (&gt;20) material during alteration. It Also requires the retention of only the low&nbsp;</span><sup>206</sup><span>Pb/&nbsp;</span><sup>204</sup><span>Pb component of the Ordovician to Devonian&nbsp;</span>sedimentary<span>&nbsp;rocks. This critical step is possible only if the high&nbsp;</span><sup>206</sup><span>Pb/&nbsp;</span><sup>204</sup><span>Pb values are contained&nbsp;</span>in<span>&nbsp;readily dissolvable mineral phases, whereas the low&nbsp;</span><sup>206</sup><span>Pb/&nbsp;</span><sup>204</sup><span>Pb values are found only&nbsp;</span>in<span>&nbsp;refractory minerals that released Pb during a final alteration stage just prior deposition of auriferous arsenian pyrite. Distinguishing between Pb transported with the ore&nbsp;</span>fluid<span>&nbsp;or inherited from the site of mineral deposition is not straightforward; however, it is simpler to explain the Pb isotope compositions of ore-stage arsenian pyrite and fluorite&nbsp;</span>in<span>&nbsp;two different but spatially related&nbsp;</span>Carlin<span>-</span>type<span>&nbsp;</span>deposits<span>&nbsp;(</span>Getchell<span>&nbsp;and&nbsp;</span>Turquoise<span>&nbsp;</span>Ridge<span>) with different host rocks by input of Pb with the ore&nbsp;</span>fluid<span>. Once the limited Pb&nbsp;</span>in<span>&nbsp;the hydrothermal&nbsp;</span>fluid<span>&nbsp;was exhausted by incorporation&nbsp;</span>in<span>&nbsp;ore-stage arsenian pyrite or other ore-stage minerals, Pb from the second&nbsp;</span>source<span>, the Ordovician to Devonian&nbsp;</span>sedimentary<span>&nbsp;</span>rock<span>&nbsp;sequences, became available for incorporation&nbsp;</span>in<span>&nbsp;some but not all of the late-stage sulfide minerals.</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.98.6.1189","issn":"03610128","usgsCitation":"Tosdal, R., Cline, J.S., Fanning, C., and Wooden, J.L., 2003, Lead in the Getchell-Turquoise ridge Carlin-type gold deposits from the perspective of potential igneous and sedimentary rock sources in Northern Nevada: Implications for fluid and metal sources: Economic Geology, v. 98, no. 6, p. 1189-1211, https://doi.org/10.2113/gsecongeo.98.6.1189.","productDescription":"23 p.","startPage":"1189","endPage":"1211","costCenters":[],"links":[{"id":387489,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United  States","state":"Nevada","otherGeospatial":"northern Nevada","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -119.981689453125,\n              40.91351257612758\n            ],\n            [\n              -114.027099609375,\n              40.91351257612758\n            ],\n            [\n              -114.027099609375,\n              42.00032514831621\n            ],\n            [\n              -119.981689453125,\n              42.00032514831621\n            ],\n            [\n              -119.981689453125,\n              40.91351257612758\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"98","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a45bce4b0c8380cd6749a","contributors":{"authors":[{"text":"Tosdal, R.
