We test the ability of the Root Zone Water Quality Model (RZWQM) to simulate watershed-scale variability due to the LSNT, and we use the optimized model to simulate long-term field N dynamics under related conditions. Autoregressive techniques and the automatic parameter calibration program PEST were used to show that RZWQM simulates significantly lower nitrate concentration in discharge from LSNT treatments compared with areas receiving fall N fertilizer applications within the tile-drained Walnut Creek, Iowa, watershed (>5 mg N L-1 difference for the third year of the treatment, 1999). This result is similar to field-measured data from a paired watershed experiment. A statistical model we developed using RZWQM simulations from 1970 to 2005 shows that early-season precipitation and early-season temperature account for 90% of the interannual variation in LSNT-based fertilizer N rates. Long-term simulations with similar average N application rates for corn (Zea mays L.) (151 kg N ha-1) show annual average N loss in tile flow of 20.4, 22.2, and 27.3 kg N ha -1 for LSNT, single spring, and single fall N applications. These results suggest that (i) RZWQM is a promising tool to accurately estimate the water quality effects of LSNT; (ii) the majority of N loss difference between LSNT and fall applications is because more N remains in the root zone for crop uptake; and (iii) year-to-year LSNT-based N rate differences are mainly due to variation in early-season precipitation and temperature.

The 3He ages, when combined with those reported previously, indicate that the local ice-cap margin began to retreat from its LLGM extent at 20.5??2.5ka, in agreement with the age of deglaciation determined from LLGM moraines elsewhere in the tropics. The ice-cap margin receded to a position at least 3km upslope for ~4.5-5.0kyr before readvancing nearly to its LLGM extent. The timing of this readvance at ~15.4ka corresponds to a large reduction of the Atlantic meridional overturning circulation (AMOC) following Heinrich Event 1. Subsequent ice-margin retreat began at 14.6??1.9ka, corresponding to a rapid resumption of the AMOC and onset of the B??lling warm interval, with the ice cap melting rapidly to complete deglaciation. Additional 3He ages obtained from a flood deposit date the catastrophic outburst of a moraine-dammed lake roughly coeval with the Younger Dryas cold interval, suggesting a more active hydrological cycle on Mauna Kea at this time. A coupled mass balance and ice dynamics model is used to constrain the climate required to generate ice caps of LLGM and readvance sizes. The depression of the LLGM equilibrium line altitude requires atmospheric cooling of 4.5??1??C, whereas the mass balance modeling indicates an accompanying increase in precipitation of as much as three times that of present. We hypothesize (1) that the LLGM temperature depression was associated with global cooling, (2) that the temperature depression that contributed to the readvance occurred in response to an atmospheric teleconnection to the North Atlantic, and (3) that the precipitation enhancement associated with both events occurred in response to a southward shift in the position of the inter-tropical convergence zone (ITCZ). Such a shift in the ITCZ would have allowed midlatitude cyclones to reach Mauna Kea more frequently which would have increased precipitation at high elevations and caused additional cooling. ?? 2010 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Earth and Planetary Science Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.epsl.2010.06.025","issn":"0012821X","usgsCitation":"Anslow, F.S., Clark, P., Kurz, M., and Hostetler, S.W., 2010, Geochronology and paleoclimatic implications of the last deglaciation of the Mauna Kea Ice Cap, Hawaii: Earth and Planetary Science Letters, v. 297, no. 1-2, p. 234-248, https://doi.org/10.1016/j.epsl.2010.06.025.","startPage":"234","endPage":"248","numberOfPages":"15","costCenters":[],"links":[{"id":245235,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217300,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.epsl.2010.06.025"}],"volume":"297","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1732e4b0c8380cd55409","contributors":{"authors":[{"text":"Anslow, Faron S.","contributorId":35442,"corporation":false,"usgs":true,"family":"Anslow","given":"Faron","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":461056,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Clark, P.U.","contributorId":78449,"corporation":false,"usgs":true,"family":"Clark","given":"P.U.","email":"","affiliations":[],"preferred":false,"id":461059,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kurz, M.D.","contributorId":66845,"corporation":false,"usgs":true,"family":"Kurz","given":"M.D.","email":"","affiliations":[],"preferred":false,"id":461058,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hostetler, S.

REE content is distinctive at the formation scale, with TMF samples exhibiting generally higher overall REE content and greater variability in REE enrichment than JRF samples. Moreover, JRF bones exhibit relative enrichment in heavy REE, whereas TMF bones span heavy and light enrichment fields in roughly equal proportions. TMF bones are also characterized by more negative Ce anomalies and greater U enrichment than JRF bones, which is consistent with more oxidizing diagenetic conditions in the TMF. Bonebeds in both formations show general consistency in REE content, with no indication of spatial or temporal mixing within sites. Previous studies, however, suggest that the bonebeds in question are attritional assemblages that accumulated over considerable time spans. The absence of geochemical evidence for mixing is consistent with diagenesis transpiring in settings that remained chemically and hydrologically stable during recrystallization. Lithology-related patterns in REE content were also compared, and TMF bones recovered from fluvial sandstones show relative enrichment in heavy REE when compared with bones recovered from fine-grained floodplain deposits. In contrast, JRF bones, regardless of lithologic context (sandstone versus mudstone), exhibit similar patterns of REE uptake. This result is consistent with previous reconstructions that suggest that channel-hosted microfossil bonebeds of the JRF developed via the reworking of preexisting concentrations embedded in the interfluve. Geochemical data further indicate that reworked elements were potentially delivered to channels in a recrystallized condition, which is consistent with rapid adsorption of REE postmortem.

This information is lacking for many ecosystems including the Sierra Nevada in California, USA. We investigated fuel deposition rates and stand characteristics of seven montane and four subalpine conifers in the Sierra Nevada. We collected foliage, miscellaneous bark and crown fragments, cones, and woody fuel classes from four replicate plots each in four stem diameter size classes for each species, for a total of 176 sampling sites. We used these data to develop predictive equations for each fuel class and diameter size class of each species based on stem and crown characteristics. There were consistent species and diameter class differences in the annual amount of foliage and fragments deposited. Foliage deposition rates ranged from just over 50 g m<sup>-2</sup> year<sup>-1</sup> in small diameter mountain hemlock stands to ???300 g m<sup>-2</sup> year<sup>-1</sup> for the three largest diameter classes of giant sequoia. The deposition rate for most woody fuel classes increased from the smallest diameter class stands to the largest diameter class stands. Woody fuel deposition rates varied among species as well. The rates for the smallest woody fuels ranged from 0.8 g m<sup>-2</sup> year<sup>-1</sup> for small diameter stands of Jeffrey pine to 126.9 g m<sup>-2</sup> year<sup>-1</sup> for very large diameter stands of mountain hemlock. Crown height and live crown ratio were the best predictors of fuel deposition rates for most fuel classes and species. Both characteristics reflect the amount of crown biomass including foliage and woody fuels. Relationships established in this study allow predictions of fuel loads to be made on a stand basis for each of these species under current and possible future conditions. These predictions can be used to estimate fuel treatment longevity, assist in determining fuel model transitions, and predict future changes in fuel bed characteristics.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Forest Ecology and Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.foreco.2010.02.024","issn":"03781127","usgsCitation":"van Wagtendonk, J., and Moore, P., 2010, Fuel deposition rates of montane and subalpine conifers in the central Sierra Nevada, California, USA: Forest Ecology and Management, v. 259, no. 10, p. 2122-2132, https://doi.org/10.1016/j.foreco.2010.02.024.","startPage":"2122","endPage":"2132","numberOfPages":"11","costCenters":[],"links":[{"id":217328,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.foreco.2010.02.024"},{"id":245268,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"259","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1409e4b0c8380cd54895","contributors":{"authors":[{"text":"van Wagtendonk, J.

Explanatory variables that could be used for identifying potential bacteria loading mechanisms, such as bed shear stress due to a combined wave-current boundary layer and wave runup on the beach surface, were derived from an existing wave and current database. The derived hydrodynamic variables, along with the actual observed E. coli concentrations in the submerged and foreshore sands, were expected to reveal bacteria loading through nearshore sediment resuspension and swash on the beach surface, respectively. Based on the observation that onshore waves tend to result in a more active hydrodynamic system at this embayed beach, multiple linear regression analysis of onshore-wave cases further indicated the significance of sediment resuspension and the interaction of swash with gull-droppings in explaining the variability of E. coli concentration in the knee-deep water. For cases with longshore currents, numerical simulations using the Princeton Ocean Model revealed current circulation patterns inside the embayment, which can effectively entrain bacteria from the swash zone into the central area of the embayed beach water and eventually release them out of the embayment. The embayed circulation patterns are consistent with the statistical results that identified that 1) the submerged sediment was an additional net source of E. coli to the offshore water and 2) variability of E. coli concentration in the knee-deep water contributed adversely to that in the offshore water for longshore-current cases. The embayed beach setting and the statistical and numerical methods used in the present study have wide applicability for analyzing recreational water quality at similar marine and freshwater sites. ?? 2010 American Chemical Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es100797r","issn":"0013936X","usgsCitation":"Ge, Z., Nevers, M., Schwab, D., and Whitman, R., 2010, Coastal loading and transport of Escherichia coli at an embayed beach in Lake Michigan: Environmental Science & Technology, v. 44, no. 17, p. 6731-6737, https://doi.org/10.1021/es100797r.","startPage":"6731","endPage":"6737","numberOfPages":"7","costCenters":[],"links":[{"id":217354,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es100797r"},{"id":245298,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"44","issue":"17","noUsgsAuthors":false,"publicationDate":"2010-08-05","publicationStatus":"PW","scienceBaseUri":"5059f785e4b0c8380cd4cb74","contributors":{"authors":[{"text":"Ge, Z.","contributorId":99769,"corporation":false,"usgs":true,"family":"Ge","given":"Z.","email":"","affiliations":[],"preferred":false,"id":461090,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nevers, M.B.","contributorId":13787,"corporation":false,"usgs":true,"family":"Nevers","given":"M.B.","email":"","affiliations":[],"preferred":false,"id":461087,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schwab, D.J.","contributorId":23730,"corporation":false,"usgs":true,"family":"Schwab","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":461088,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Whitman, R.L.","contributorId":69750,"corporation":false,"usgs":true,"family":"Whitman","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":461089,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The method can be applied to separate eight steroid standards: progesterone, 17α,20β-dihydroxypregn-4-en-3-one, 17α-hydroxyprogesterone, testosterone, estrone, 11-ketotestosterone, ethynyl estradiol, and 17β-estradiol. Based on screening of plasma, the performance of the analytical method was determined for 17α,20β-dihydroxypregn-4-en-3-one, testosterone, 11-ketotestosterone, and 17β-estradiol. The within-day reproducibility in migration time for these four steroids in aqueous samples was ≤2%. Steroid quantification was accomplished using a calibration curve obtained with external standards. Plasma samples from fish collected from the Choptank and Severn Rivers, Maryland, USA, stored for up to one year were extracted with ethyl acetate and then further processed with anion exchange and hydrophobic solid phase extraction cartridges. The recovery of testosterone and 17β-estradiol from yellow perch plasma was 84 and 85%, respectively. Endogenous levels of testosterone ranged from 0.9 to 44 ng/ml, and when detected 17α,20β-dihydroxypregn-4-en-3-one ranged from 5 to 34 ng/ml. The reported values for testosterone correlated well with the immunoassay technique. Endogenous concentrations of 17β-estradiol were ≤1.7 ng/ml. 11-Ketotestosterone was not quantified because of a suspected interferant. Higher levels of 17α,20β-dihydroxypregn-4-en-3-one were found in male and female fish in which 17β-estradiol was not detected.

In this study, tools developed to estimate earthquake probability from paleoseismic horizons are adapted to estimate submarine landslide probability. In both types of estimates, one has to account for the uncertainty associated with age-dating individual events as well as the open time intervals before and after the observed sequence of landslides. For observed sequences of submarine landslides, we typically only have the age date of the youngest event and possibly of a seismic horizon that lies below the oldest event in a landslide sequence. We use an empirical Bayes analysis based on the Poisson-Gamma conjugate prior model specifically applied to the landslide probability problem. This model assumes that landslide events as imaged in geophysical data are independent and occur in time according to a Poisson distribution characterized by a rate parameter &lambda;. With this method, we are able to estimate the most likely value of &lambda; and, importantly, the range of uncertainty in this estimate. Examples considered include landslide sequences observed in the Santa Barbara Channel, California, and in Port Valdez, Alaska.

Vegetation characteristics of bed sites influence thermal protection of neonates and concealment from predators. Although previous studies describe bed site selection of neonatal white-tailed deer (Odocoileus virginianus) in regions of forested cover, none determined microhabitat effects on neonate bed site selection in the Northern Great Plains, an area of limited forest cover. During summers 2007–2009, we investigated bed site selection (n  =  152) by 81 radiocollared neonate white-tailed deer in north-central South Dakota, USA. We documented 80 (52.6%) bed sites in tallgrass–Conservation Reserve Program lands, 35 (23.0%) bed sites in forested cover, and 37 (24.3%) in other habitats (e.g., pasture, alfalfa, wheat). Bed site selection varied with age and sex of neonate. Tree canopy cover (P < 0.001) and tree basal area (P < 0.001) decreased with age of neonates, with no bed sites observed in forested cover after 18 days of age. Male neonates selected sites with less grass cover (P < 0.001), vertical height of understory vegetation (P < 0.001), and density of understory vegetation (P < 0.001) but greater bare ground (P  =  0.047), litter (P  =  0.028), and wheat (P  =  0.044) than did females. Odds of bed site selection increased 3.5% (odds ratio  =  1.035, 95% CI  =  1.008–1.062) for every 1-cm increase in vertical height of understory vegetation. Management for habitat throughout the grasslands of South Dakota that maximizes vertical height of understory vegetation would enhance cover characteristics selected by neonates.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Wildlife Society","publisherLocation":"Bethesda, MD","doi":"10.2193/2009-399","issn":"0022541X","usgsCitation":"Grovenburg, T., Jacques, C., Klaver, R., and Jenks, J., 2010, Bed site selection by neonate deer in grassland habitats on the northern Great Plains: Journal of Wildlife Management, v. 74, no. 6, p. 1250-1256, https://doi.org/10.2193/2009-399.","productDescription":"7 p.","startPage":"1250","endPage":"1256","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":217356,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2009-399"},{"id":245300,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Great Plains","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.2,28.2 ], [ -114.2,54.1 ], [ -95.6,54.1 ], [ -95.6,28.2 ], [ -114.2,28.2 ] ] ] } } ] }","volume":"74","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f03ce4b0c8380cd4a67f","contributors":{"authors":[{"text":"Grovenburg, T.W.","contributorId":78163,"corporation":false,"usgs":true,"family":"Grovenburg","given":"T.W.","affiliations":[],"preferred":false,"id":461103,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jacques, C.N.","contributorId":19378,"corporation":false,"usgs":true,"family":"Jacques","given":"C.N.","email":"","affiliations":[],"preferred":false,"id":461100,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Klaver, R.

Based on the premise that the worth of data increases in proportion to its ability to reduce the uncertainty of key model predictions, the methodology can be used to compare the worth of different data types, gathered at different locations within study areas of arbitrary complexity. The method is applied to a hypothetical nonlinear, variable density numerical model of salt and heat transport. The relative utilities of temperature and concentration measurements at different locations within the model domain are assessed in terms of their ability to reduce the uncertainty associated with predictions of movement of the salt water interface in response to a decrease in fresh water recharge. In order to test the sensitivity of the method to nonlinear model behavior, analyses were repeated for multiple realizations of system properties. Rankings of observation worth were similar for all realizations, indicating robust performance of the methodology when employed in conjunction with a highly nonlinear model. The analysis showed that while concentration and temperature measurements can both aid in the prediction of interface movement, concentration measurements, especially when taken in proximity to the interface at locations where the interface is expected to move, are of greater worth than temperature measurements. Nevertheless, it was also demonstrated that pairs of temperature measurements, taken in strategic locations with respect to the interface, can also lead to more precise predictions of interface movement.

Ultimately, this integrated simulator will be used as a means to organize information, illustrate potential system responses, and facilitate communication within a participatory modeling framework. Initial results show the potential system response to different zoning policy scenarios in terms of the spatial patterns of development, which is referred to as urban form, and consequent impacts on groundwater levels. These results illustrate how the integrated simulator is capable of representing the complexity of the system. From a groundwater modeling perspective, the most important aspect of the integration is that the simulator generates stresses on the groundwater system within the simulation in contrast to the traditional approach that requires the user to specify the stresses through time.

It carries three remote-sensing sensors: 1) the Advanced Visible and Near-Infrared Radiometer type 2 (AVNIR-2); 2) the Panchromatic Remote-Sensing Instrument for Stereo Mapping (PRISM); and 3) the Phased-Array type L-band Synthetic Aperture Radar (PALSAR). Within the framework of ALOS Data European Node, as part of the European Space Agency (ESA), the European Space Research Institute worked alongside JAXA to provide contributions to the ALOS commissioning phase plan. This paper summarizes the strategy that was adopted by ESA to define and implement a data verification plan for missions operated by external agencies; these missions are classified by the ESA as third-party missions. The ESA was supported in the design and execution of this plan by GAEL Consultant. The verification of ALOS optical data from PRISM and AVNIR-2 sensors was initiated 4 months after satellite launch, and a team of principal investigators assembled to provide technical expertise. This paper includes a description of the verification plan and summarizes the methodologies that were used for radiometric, geometric, and image quality assessment. The successful completion of the commissioning phase has led to the sensors being declared fit for operations. The consolidated measurements indicate that the radiometric calibration of the AVNIR-2 sensor is stable and agrees with the Landsat-7 Enhanced Thematic Mapper Plus and the Envisat MEdium-Resolution Imaging Spectrometer calibration. The geometrical accuracy of PRISM and AVNIR-2 products improved significantly and remains under control. The PRISM modulation transfer function is monitored for improved characterization.</span></p>","language":"English","publisher":"IEEE","doi":"10.1109/TGRS.2010.2048714","issn":"01962892","usgsCitation":"Saunier, S., Goryl, P., Chander, G., Santer, R., Bouvet, M., Collet, B., Mambimba, A., and Kocaman, A.S., 2010, Radiometric, geometric, and image quality assessment of ALOS AVNIR-2 and PRISM sensors: IEEE Transactions on Geoscience and Remote Sensing, v. 48, no. 10, p. 3855-3866, https://doi.org/10.1109/TGRS.2010.2048714.","productDescription":"12 p.","startPage":"3855","endPage":"3866","numberOfPages":"12","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":246080,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218098,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1109/TGRS.2010.2048714"}],"volume":"48","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9418e4b0c8380cd811d8","contributors":{"authors":[{"text":"Saunier, S.","contributorId":96914,"corporation":false,"usgs":true,"family":"Saunier","given":"S.","email":"","affiliations":[],"preferred":false,"id":461550,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Goryl, P.","contributorId":58484,"corporation":false,"usgs":true,"family":"Goryl","given":"P.","email":"","affiliations":[],"preferred":false,"id":461547,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chander, G.","contributorId":51449,"corporation":false,"usgs":true,"family":"Chander","given":"G.","affiliations":[],"preferred":false,"id":461546,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Santer, R.","contributorId":9884,"corporation":false,"usgs":true,"family":"Santer","given":"R.","email":"","affiliations":[],"preferred":false,"id":461543,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bouvet, M.","contributorId":25375,"corporation":false,"usgs":true,"family":"Bouvet","given":"M.","email":"","affiliations":[],"preferred":false,"id":461544,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Collet, B.","contributorId":95731,"corporation":false,"usgs":true,"family":"Collet","given":"B.","email":"","affiliations":[],"preferred":false,"id":461549,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Mambimba, A.","contributorId":26172,"corporation":false,"usgs":true,"family":"Mambimba","given":"A.","email":"","affiliations":[],"preferred":false,"id":461545,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Kocaman, Aksakal S.","contributorId":89757,"corporation":false,"usgs":true,"family":"Kocaman","given":"Aksakal","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":461548,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

The fault zone is composed of distinct structural and hydrogeological components. Previous work on the fault rocks is extended to the map scale where a distinctive fault core shows a spectrum of different fault-related breccias. These include predominantly clast-supported breccias with angular clasts that are cut by zones containing breccias with rounded clasts that are also clast supported. These are further cut by breccias that are predominantly matrix supported with angular and rounded clasts. The fault-core breccias are surrounded by a heterogeneously fractured damage zone. Breccias are bounded between major, silicified slip surfaces, forming large pod-like structures, systematically oriented with long axes parallel to slip. Matrix-supported breccias have multiply brecciated, angular and rounded clasts revealing episodic deformation and fluid flow. These breccias have a quartz-rich matrix with microcrystalline anhedral, equant, and pervasively conformable mosaic texture. The breccia pods are interpreted to have formed by decompression boiling and rapid precipitation of hydrothermal fluids whose flow was induced by coseismic, hybrid dilatant-shear deformation and hydraulic connection to a geothermal reservoir. The addition of hydrothermal silica cement localized in the core at the map scale causes fault-zone widening, local sealing, and mechanical heterogeneities that impact the evolution of the fault zone throughout the seismic cycle. ?? 2010.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Structural Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jsg.2010.03.004","issn":"01918141","usgsCitation":"Caine, J.S., Bruhn, R., and Forster, C., 2010, Internal structure, fault rocks, and inferences regarding deformation, fluid flow, and mineralization in the seismogenic Stillwater normal fault, Dixie Valley, Nevada: Journal of Structural Geology, v. 32, no. 11, p. 1576-1589, https://doi.org/10.1016/j.jsg.2010.03.004.","startPage":"1576","endPage":"1589","numberOfPages":"14","costCenters":[],"links":[{"id":246068,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218087,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jsg.2010.03.004"}],"volume":"32","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3d2fe4b0c8380cd63388","contributors":{"authors":[{"text":"Caine, Jonathan S. 0000-0002-7269-6989 jscaine@usgs.gov","orcid":"https://orcid.org/0000-0002-7269-6989","contributorId":1272,"corporation":false,"usgs":true,"family":"Caine","given":"Jonathan","email":"jscaine@usgs.gov","middleInitial":"S.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":false,"id":461542,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bruhn, R.L.","contributorId":46972,"corporation":false,"usgs":true,"family":"Bruhn","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":461541,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Forster, C.B.","contributorId":26170,"corporation":false,"usgs":true,"family":"Forster","given":"C.B.","email":"","affiliations":[],"preferred":false,"id":461540,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The standard engineering method for assessing liquefaction potential, the Seed–Idriss simplified procedure, successfully predicted the liquefaction despite the small earthquake magnitude.

The objective of the project was to evaluate the environmental effects of land-use changes, with a focus on understanding how the spatial distribution throughout a watershed influences their effectiveness.The Soil and Water AssessmentTool (SWAT) water quality model was applied to the Squaw Creek watershed, which covers 4,730 ha (11,683 ac) of prime agriculture land in southern Iowa. The model was calibrated (2000 to 2004) and validated (1996 to 1999) for overall watershed hydrology and for streamflow and nitrate loadings at the watershed outlet on an annual and monthly basis. Four scenarios for land-use change were evaluated including one scenario consistent with recent land-use changes and three scenarios focused on land-use change on highly erodible land areas, upper basin areas, and floodplain areas. Results for the Squaw Creek watershed suggested that nitrate losses were sensitive to land-use change. If land-use patterns were restored to 1990 conditions, nitrate loads may be reduced 7% to 47% in the watershed and subbasins, whereas converting row crops to grass in highly erodible land, upper basin, and floodplain areas would reduce nitrate loads by 47%, 16%, and 8%, respectively. These SWAT model simulations can provide guidance on how to begin targeting land-use change for nitrate load reductions in agricultural watersheds.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Soil and Water Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2489/jswc.65.6.342","issn":"00224561","usgsCitation":"Jha, M., Schilling, K.E., Gassman, P.W., and Wolter, C., 2010, Targeting land-use change for nitratenitrogen load reductions in an agricultural watershed: Journal of Soil and Water Conservation, v. 65, no. 6, p. 342-352, https://doi.org/10.2489/jswc.65.6.342.","startPage":"342","endPage":"352","numberOfPages":"11","costCenters":[],"links":[{"id":475835,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.2489/jswc.65.6.342","text":"Publisher Index Page"},{"id":217984,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2489/jswc.65.6.342"},{"id":245959,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"65","issue":"6","noUsgsAuthors":false,"publicationDate":"2010-11-02","publicationStatus":"PW","scienceBaseUri":"505ba3e5e4b08c986b31ff7c","contributors":{"authors":[{"text":"Jha, M.K.","contributorId":58127,"corporation":false,"usgs":true,"family":"Jha","given":"M.K.","email":"","affiliations":[],"preferred":false,"id":461451,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schilling, K.

We investigated longitudinal and seasonal patterns in the Upper Mississippi River (UMR) using long-term data (1994-2005) from five study reaches that spanned 1300 km of the UMR. Lake Pepin, a natural lake in the most upstream study reach, had a clear effect on suspended material in the river. Suspended solids and total phosphorus (TP) concentrations were substantially lower downstream of the lake and percent organic material (OM%) in suspension was higher. Below L. Pepin, mean total and organic suspended solids (TSS, OSS) and TP increased downriver and exhibited approximately log-linear relationships with catchment area, whereas OM% declined substantially downriver. Despite the downriver increase in TSS and OSS, concentrations similar to those above L. Pepin do not occur until ~370 km downriver indicating the extent of the influence of L. Pepin on the UMR. Chlorophyll concentrations were lower in the most downstream study reach, likely reflecting the shorter residence time and poor light climate, but there was not a consistent longitudinal decline in chlorophyll across the study reaches. Dissolved silica (DSi), DSi:TN, and DSi:TP declined downriver suggesting that DSi uptake and sedimentation by river phytoplankton may be reducing DSi transport in the river, and indicating that the eutrophication of the river may contribute to a reduction of DSi export to the Gulf of Mexico. ?? 2010 US Government: USGS.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrobiologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10750-010-0282-z","issn":"00188158","usgsCitation":"Houser, J., Bierman, D., Burdis, R., and Soeken-Gittinger, L.A., 2010, Longitudinal trends and discontinuities in nutrients, chlorophyll, and suspended solids in the Upper Mississippi River: Implications for transport, processing, and export by large rivers: Hydrobiologia, v. 651, no. 1, p. 127-144, https://doi.org/10.1007/s10750-010-0282-z.","startPage":"127","endPage":"144","numberOfPages":"18","costCenters":[],"links":[{"id":217944,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10750-010-0282-z"},{"id":245917,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"651","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-05-16","publicationStatus":"PW","scienceBaseUri":"505a49c4e4b0c8380cd68893","contributors":{"authors":[{"text":"Houser, J.N.","contributorId":91603,"corporation":false,"usgs":true,"family":"Houser","given":"J.N.","email":"","affiliations":[],"preferred":false,"id":461435,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bierman, D.W.","contributorId":73855,"corporation":false,"usgs":true,"family":"Bierman","given":"D.W.","email":"","affiliations":[],"preferred":false,"id":461433,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Burdis, R.M.","contributorId":22181,"corporation":false,"usgs":true,"family":"Burdis","given":"R.M.","email":"","affiliations":[],"preferred":false,"id":461432,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Soeken-Gittinger, L.

Even with much experimental effort2-12, the weakening mechanisms have remained enigmatic. Here we present evidence for dynamic weakening of experimental faults that are sheared at velocities approaching earthquake slip rates. The experimental faults, which were made of room-dry, solid granite blocks, quickly wore to form a fine-grain rock powder known as gouge. At modest slip velocities of 10-60mms-1, this newly formed gouge organized itself into a thin deforming layer that reduced the fault's strength by a factor of 2-3. After slip, the gouge rapidly 'aged' and the fault regained its strength in a matter of hours to days. Therefore, only newly formed gouge can weaken the experimental faults. Dynamic gouge formation is expected to be a common and effective mechanism of earthquake instability in the brittle crust as (1) gouge always forms during fault slip5,10,12-20; (2) fault-gouge behaves similarly to industrial powder lubricants21; (3) dynamic gouge formation explains various significant earthquake properties; and (4) gouge lubricant can form for a wide range of fault configurations, compositions and temperatures15. ?? 2010 Macmillan Publishers Limited.

In addition, we have observed isotopic reversals in the ??2H in the deepest samples. Isotopic reversals cannot be explained by current models of hydrocarbon gas generation. Previous observations of partial isotopic reversals have been explained by mixing between gases from different sources and thermal maturities. We have constructed a model which, in addition to mixing, requires Rayleigh fractionation of C2 and C3 to cause enrichment in 13C and create reversals. In the deepest samples, the normal trend of increasing enrichment of 13C and 2H in methane with increasing depth reverses and 2H becomes depleted as 13C becomes enriched. We propose that the reactions that drive Rayleigh fractionation of C2 and C3 involve redox reactions with transition metals and water at late stages of catagenesis at temperatures on the order of 250-300??C. Published ab initio calculated fractionation factors for C-C bond breaking in ethane at these temperatures are consistent with our observations. The reversed trend in ??2H in methane appears to be caused by isotopic exchange with formation water at the same temperatures. Our interpretation that Rayleigh fractionation during redox reactions is causing isotopic reversals has important implications for natural gas resources in deeply buried sedimentary basins. ?? 2010.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Organic Geochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.orggeochem.2010.09.008","issn":"01466380","usgsCitation":"Burruss, R., and Laughrey, C., 2010, Carbon and hydrogen isotopic reversals in deep basin gas: Evidence for limits to the stability of hydrocarbons: Organic Geochemistry, v. 41, no. 12, p. 1285-1296, https://doi.org/10.1016/j.orggeochem.2010.09.008.","startPage":"1285","endPage":"1296","numberOfPages":"12","costCenters":[],"links":[{"id":246105,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218121,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.orggeochem.2010.09.008"}],"volume":"41","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f35ae4b0c8380cd4b73e","contributors":{"authors":[{"text":"Burruss, R.C. 0000-0001-6827-804X","orcid":"https://orcid.org/0000-0001-6827-804X","contributorId":99574,"corporation":false,"usgs":true,"family":"Burruss","given":"R.C.","affiliations":[],"preferred":false,"id":461411,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Laughrey, C.D.","contributorId":53212,"corporation":false,"usgs":true,"family":"Laughrey","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":461410,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

However, we show here that complex zircon age populations extending back hundreds of thousands of years from eruption age indicate that magmas regularly stall in the crust, cool and crystallize beneath the volcano, and are then rejuvenated and incorporated by hotter, young magmas on their way to the surface. Estimated dissolution times suggest that entrained zircon generally resided in rejuvenating magmas for no more than about a century. Zircon elemental compositions reflect the increasing influence of mafic input into the system through time, recording growth from hotter, less evolved magmas tens of thousands of years prior to the appearance of mafic magmas at the surface, or changes in whole-rock geochemistry and petrology, and providing a new, time-correlated record of this evolution independent of the eruption history. Zircon data thus reveal the history of the hidden, long-lived intrusive portion of the Mount St. Helens system, where melt and crystals are stored for as long as hundreds of thousands of years and interact with fresh influxes of magmas that traverse the intrusive reservoir before erupting. ?? 2010 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/G31285.1","issn":"00917613","usgsCitation":"Claiborne, L., Miller, C.F., Flanagan, D., Clynne, M., and Wooden, J.L., 2010, Zircon reveals protracted magma storage and recycling beneath Mount St. Helens: Geology, v. 38, no. 11, p. 1011-1014, https://doi.org/10.1130/G31285.1.","startPage":"1011","endPage":"1014","numberOfPages":"4","costCenters":[],"links":[{"id":218111,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/G31285.1"},{"id":246093,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"38","issue":"11","noUsgsAuthors":false,"publicationDate":"2010-10-12","publicationStatus":"PW","scienceBaseUri":"505bd28fe4b08c986b32f8ab","contributors":{"authors":[{"text":"Claiborne, L.L.","contributorId":45543,"corporation":false,"usgs":true,"family":"Claiborne","given":"L.L.","email":"","affiliations":[],"preferred":false,"id":461405,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Miller, C.

Trapping was conducted at seven sites from 26 March to 2 July 2004. Overall larval catch was low (379 individuals in 220 hours of trapping). More larval White Suckers were captured than all other species. Vectors fitted to nonparametric multidimensional scaling ordinations suggested that temperature was highly correlated to fish communities captured at our sites. Survival of larval Fathead Minnows was examined in situ at six sites from 13 May to 11 June 2004 in the same system. Larval survival was lower, but not significantly different between sites directly downstream of AMD-impacted tributaries (40% survival) and non-AMD sites (52% survival). The lower survival was caused by a significant mortality event at one site that coincided with acute pH depression in an AMD tributary immediately upstream of the site. Results from a Cox proportional hazard test suggests that low pH is having a significant negative influence on larval fish survival in this system. The results from this research indicate that the combination of low pH events and elevated temperature are negatively influencing the larval fish populations of the Stony River watershed. Management actions that address these problems would have the potential to substantially increase both reproduction rates and larval survival, therefore greatly enhancing the fishery.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Northeastern Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1656/045.017.0405","issn":"10926194","usgsCitation":"Hafs, A.W., Horn, C., Mazik, P.M., and Hartman, K., 2010, Influences of acid mine drainage and thermal enrichment on stream fish reproduction and larval survival: Northeastern Naturalist, v. 17, no. 4, p. 575-592, https://doi.org/10.1656/045.017.0405.","startPage":"575","endPage":"592","numberOfPages":"18","costCenters":[],"links":[{"id":246078,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218096,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1656/045.017.0405"}],"volume":"17","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3b9be4b0c8380cd626c2","contributors":{"authors":[{"text":"Hafs, Andrew W.","contributorId":57308,"corporation":false,"usgs":true,"family":"Hafs","given":"Andrew","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":461394,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Horn, C.D.","contributorId":83773,"corporation":false,"usgs":true,"family":"Horn","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":461396,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mazik, P.

Instead, different grid resolutions require different estimated values. Grid refinement strategies considered include global refinement of the entire model and local refinement of part of the stream. Three methods of calculating the conductance of the Cauchy boundary conditions are investigated. Single- and multi-layer models with narrow and wide streams produced stream leakages that differ by as much as 122% as the grid is refined. Similar results occur for globally and locally refined grids, but the latter required as little as one-quarter the computer execution time and memory and thus are useful for addressing some scale issues of stream–aquifer interactions. Results suggest that existing grid-size criteria for simulating stream–aquifer interactions are useful for one-layer models, but inadequate for three-dimensional models. The grid dependence of the conductance terms suggests that values for refined models using, for example, finite difference or finite-element methods, cannot be determined from previous coarse-grid models or field measurements. Our examples demonstrate the need for a method of obtaining conductances that can be translated to different grid resolutions and provide definitive test cases for investigating alternative conductance formulations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Advances in Water Resources","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.advwatres.2010.01.008","issn":"03091708","usgsCitation":"Mehl, S., and Hill, M.C., 2010, Grid-size dependence of Cauchy boundary conditions used to simulate stream-aquifer interactions: Advances in Water Resources, v. 33, no. 4, p. 430-442, https://doi.org/10.1016/j.advwatres.2010.01.008.","productDescription":"13 p.","startPage":"430","endPage":"442","costCenters":[{"id":434,"text":"National Research Program","active":false,"usgs":true}],"links":[{"id":218044,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.advwatres.2010.01.008"},{"id":246022,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"33","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2a70e4b0c8380cd5b1a5","contributors":{"authors":[{"text":"Mehl, S.","contributorId":20114,"corporation":false,"usgs":true,"family":"Mehl","given":"S.","affiliations":[],"preferred":false,"id":461361,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hill, M.

Logging-while-drilling (LWD), coring, and wire-line logging confirmed gas hydrate dominantly in fractures at four borehole sites spanning a 500m transect. Three-dimensional (3D) seismic data were subsequently used to image the fractured system and explain the occurrence of gas hydrate associated with the fractures. A system of two fault-sets was identified, part of a typical passive margin tectonic setting. The LWD-derived fracture network at Hole NGHP-01-10A is to some extent seen in the seismic data and was mapped using seismic coherency attributes. The fractured system around Site NGHP-01-10 extends over a triangular-shaped area of ~2.5 km2 defined using seismic attributes of the seafloor reflection, as well as \" seismic sweetness\" at the base of the gas hydrate occurrence zone. The triangular shaped area is also showing a polygonal (nearly hexagonal) fault pattern, distinct from other more rectangular fault patterns observed in the study area. The occurrence of gas hydrate at Site NGHP-01-10 is the result of a specific combination of tectonic fault orientations and the abundance of free gas migration from a deeper gas source. The triangular-shaped area of enriched gas hydrate occurrence is bound by two faults acting as migration conduits. Additionally, the fault-associated sediment deformation provides a possible migration pathway for the free gas from the deeper gas source into the gas hydrate stability zone. It is proposed that there are additional locations in the KG Basin with possible gas hydrate accumulation of similar tectonic conditions, and one such location was identified from the 3D seismic data ~6 km NW of Site NGHP-01-10. ?? 2010.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine and Petroleum Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.marpetgeo.2010.06.002","issn":"02648172","usgsCitation":"Riedel, M., Collett, T.S., Kumar, P., Sathe, A., and Cook, A., 2010, Seismic imaging of a fractured gas hydrate system in the Krishna-Godavari Basin offshore India: Marine and Petroleum Geology, v. 27, no. 7, p. 1476-1493, https://doi.org/10.1016/j.marpetgeo.2010.06.002.","startPage":"1476","endPage":"1493","numberOfPages":"18","costCenters":[],"links":[{"id":218058,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.marpetgeo.2010.06.002"},{"id":246038,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"27","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8b24e4b08c986b317610","contributors":{"authors":[{"text":"Riedel, M.","contributorId":65268,"corporation":false,"usgs":true,"family":"Riedel","given":"M.","email":"","affiliations":[],"preferred":false,"id":461372,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Collett, T.
