Management objectives generally seek to maximize quantifiable measures of system benefit, for instance population growth rate. Reaching these goals often requires a certain degree of learning about the system. Learning can occur by using management action in combination with a monitoring system. Furthermore, actions can be chosen strategically to obtain specific kinds of information. Formal decision making tools can choose actions to favor such learning in two ways: implicitly via the optimization algorithm that is used when there is a management objective (for instance, when using adaptive management), or explicitly by quantifying knowledge and using it as the fundamental project objective, an approach new to conservation.This paper outlines three conservation project objectives - a pure management objective, a pure learning objective, and an objective that is a weighted mixture of these two. We use eight optimization algorithms to choose actions that meet project objectives and illustrate them in a simulated conservation project. The algorithms provide a taxonomy of decision making tools in conservation management when there is uncertainty surrounding competing models of system function. The algorithms build upon each other such that their differences are highlighted and practitioners may see where their decision making tools can be improved. ?? 2010 Elsevier Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.biocon.2010.07.031","issn":"00063207","usgsCitation":"Probert, W., Hauser, C., McDonald-Madden, E., Runge, M., Baxter, P., and Possingham, H., 2011, Managing and learning with multiple models: Objectives and optimization algorithms: Biological Conservation, v. 144, no. 4, p. 1237-1245, https://doi.org/10.1016/j.biocon.2010.07.031.","startPage":"1237","endPage":"1245","numberOfPages":"9","costCenters":[],"links":[{"id":216513,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.biocon.2010.07.031"},{"id":244390,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"144","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4c89e4b0c8380cd69d0c","contributors":{"authors":[{"text":"Probert, William J.

In 1974 a national airborne survey was flown by the French firm Compagnie General de Geophysique (CGG). Following the survey the magnetic data were stored on magnetic tapes within an air conditioned archive run by GEOSURV. In 1990, the power supply to the archive was cut resulting in the present‐day poor condition of the tapes. Frontier Processing Company and the U.S. Geological Survey (USGS) have been able to recover over 99 percent of the original digital data from the CGG tapes. Preliminary reprocessing of the data yielded a total magnetic field anomaly map that reveals fine structures not evident in available published maps. Successful restoration of these comprehensive, high quality digital datasets obviates the need to resurvey the entire country, thereby saving considerable time and money. These data were delivered to GEOSURV in a standard format for further analysis and interpretation. A parallel effort by GETECH concentrated on recovering the legacy gravity data from the original field data sheets archived by IPC (Iraq Petroleum Company). These data have been compiled with more recent GEOSURV sponsored surveys thus allowing for the first time a comprehensive digital and unified national gravity database to be constructed with full principal facts. Figure 1 shows the final aeromagnetic and gravity data coverage of Iraq. The only part of Iraq lacking gravity and aeromagnetic data coverage is the mountainous areas of the Kurdish region of northeastern Iraq. Joint interpretation of the magnetic and gravity data will help guide future geophysical investigations by GEOSURV, whose ultimate aim is to discover economical mineral and energy

Although aspects of climate change may be novel (e.g., system change and nonstationarity), natural resource managers have long dealt with uncertainties and have developed corresponding approaches to decision-making. Adaptive resource management is an application of structured decision-making for recurrent decision problems with uncertainty, focusing on management objectives, and the reduction of uncertainty over time. We identified 4 types of uncertainty that characterize problems in natural resource management. We examined ways in which climate change is expected to exacerbate these uncertainties, as well as potential approaches to dealing with them. As a case study, we examined North American waterfowl harvest management and considered problems anticipated to result from climate change and potential solutions. Despite challenges expected to accompany the use of adaptive resource management to address problems associated with climate change, we conclude that adaptive resource management approaches will be the methods of choice for managers trying to deal with the uncertainties of climate change. ?? 2010 The Wildlife Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/jwmg.33","issn":"0022541X","usgsCitation":"Nichols, J., Koneff, M., Heglund, P., Knutson, M.G., Seamans, M., Lyons, J.E., Morton, J., Jones, M., Boomer, G., and Williams, B.K., 2011, Climate change, uncertainty, and natural resource management: Journal of Wildlife Management, v. 75, no. 1, p. 6-18, https://doi.org/10.1002/jwmg.33.","startPage":"6","endPage":"18","numberOfPages":"13","costCenters":[],"links":[{"id":216841,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/jwmg.33"},{"id":244737,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"75","issue":"1","noUsgsAuthors":false,"publicationDate":"2011-01-31","publicationStatus":"PW","scienceBaseUri":"5059f64fe4b0c8380cd4c6a3","contributors":{"authors":[{"text":"Nichols, J.D. 0000-0002-7631-2890","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":14332,"corporation":false,"usgs":true,"family":"Nichols","given":"J.D.","affiliations":[],"preferred":false,"id":444069,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Koneff, M.D.","contributorId":37031,"corporation":false,"usgs":true,"family":"Koneff","given":"M.D.","email":"","affiliations":[],"preferred":false,"id":444071,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Heglund, P.J.","contributorId":44505,"corporation":false,"usgs":true,"family":"Heglund","given":"P.J.","email":"","affiliations":[],"preferred":false,"id":444072,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Knutson, M.

To better understand effects of chronic wasting disease (CWD) and cougar (Puma concolor) predation, we studied mortality and recruitment of elk (Cervus elaphus) at Wind Cave National Park (WICA) during 2005-2009. We marked 202 elk (83 subadult M and 119 subadult and ad F) with Global Positioning System (GPS) collars, observed 28 deaths during 74,220 days of monitoring, and investigated 42 additional deaths of unmarked elk found dead. Survival rates were similar for males and females and averaged 0.863 (SE = 0.025) annually. Leading causes of mortality included hunting (0.065, SE = 0.019), CWD (0.034, SE = 0.012), and cougar predation (0.029, SE = 0.012). Marked elk killed by hunters and cougars typically were in good physical condition and not infected with CWD.

As climate rapidly warmed ;11 700 years ago, the range of Joshua tree contracted, leaving only the populations near what had been its northernmost limit. Its ability to spread northward into new suitable habitats after this time may have been inhibited by the somewhat earlier extinction of megafaunal dispersers, especially the Shasta ground sloth. We applied a model of climate suitability for Joshua tree, developed from its 20th-century range and climates, to future climates modeled through a set of six individual general circulation models (GCM) and one suite of 22 models for the late 21st century. All distribution data, observed climate data, and future GCM results were scaled to spatial grids of ;1 km and ;4 km in order to facilitate application within this topographically complex region. All of the models project the future elimination of Joshua tree throughout most of the southern portions of its current range. Although estimates of future monthly precipitation differ between the models, these changes are outweighed by large increases in temperature common to all the models. Only a few populations within the current range are predicted to be sustainable. Several models project significant potential future expansion into new areas beyond the current range, but the species' Historical and current rates of dispersal would seem to prevent natural expansion into these new areas. Several areas are predicted to be potential sites for relocation/ assisted migration. This project demonstrates how information from paleoecology and modern ecology can be integrated in order to understand ongoing processes and future distributions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ecological Society of America","publisherLocation":"Ithaca, NY","doi":"10.1890/09-1800.1","issn":"10510761","usgsCitation":"Cole, K.L., Ironside, K., Eischeid, J.K., Garfin, G., Duffy, P., and Toney, C., 2011, Past and ongoing shifts in Joshua tree distribution support future modeled range contraction: Ecological Applications, v. 21, no. 1, p. 137-149, https://doi.org/10.1890/09-1800.1.","startPage":"137","endPage":"149","numberOfPages":"13","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":216754,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/09-1800.1"},{"id":244640,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a757fe4b0c8380cd77ba4","contributors":{"authors":[{"text":"Cole, Kenneth L.","contributorId":48533,"corporation":false,"usgs":true,"family":"Cole","given":"Kenneth","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":444044,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ironside, Kirsten","contributorId":19808,"corporation":false,"usgs":true,"family":"Ironside","given":"Kirsten","affiliations":[],"preferred":false,"id":444043,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Eischeid, Jon K.","contributorId":70214,"corporation":false,"usgs":true,"family":"Eischeid","given":"Jon","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":444046,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Garfin, Gregg","contributorId":97740,"corporation":false,"usgs":true,"family":"Garfin","given":"Gregg","affiliations":[],"preferred":false,"id":444048,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Duffy, Phil","contributorId":50756,"corporation":false,"usgs":true,"family":"Duffy","given":"Phil","email":"","affiliations":[],"preferred":false,"id":444045,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Toney, Chris","contributorId":86598,"corporation":false,"usgs":true,"family":"Toney","given":"Chris","email":"","affiliations":[],"preferred":false,"id":444047,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Models are assessed for the relationships between basin formation and mare basalt emplacement. Mare basalt emplacement on the western nearside limb began prior to the Orientale event as evidenced by the presence of cryptomaria. The earliest post-Orientale-event mare basalt emplacement occurred in the center of the basin (Mare Orientale) and postdated the formation of the Orientale Basin by about 60-100 Ma. Over the next several hundred million years, basalt patches were emplaced first along the base of the Outer Rook ring (Lacus Veris) and then along the base of the Cordillera ring (Lacus Autumni), with some overlap in ages. The latest basalt patches are as young as some of the youngest basalt deposits on the lunar nearside. M3 data show several previously undetected mare patches on the southwestern margins of the basin interior. Regardless, the previously documented increase in mare abundance from the southwest toward the northeast is still prominent. We attribute this to crustal and lithospheric trends moving from the farside to the nearside, with correspondingly shallower density and thermal barriers to basaltic magma ascent and eruption toward the nearside. The wide range of model ages for Orientale mare deposits (3.70-1.66 Ga) mirrors the range of nearside mare ages, indicating that the small amount of mare fill in Orientale is not due to early cessation of mare emplacement but rather to limited volumes of extrusion for each phase during the entire period of nearside mare basalt volcanism. This suggests that nearside and farside source regions may be similar but that other factors, such as thermal and crustal thickness barriers to magma ascent and eruption, may be determining the abundance of surface deposits on the limbs and farside. The sequence, timing, and elevation of mare basalt deposits suggest that regional basin-related stresses exerted control on their distribution. Our analysis clearly shows that Orientale serves as an excellent example of the early stages of the filling of impact basins with mare basalt.

Invasive Burmese pythons (Python molurus bivittatus) are established over thousands of square kilometres of southern Florida, USA, and consume a wide range of native vertebrates. Few tools are available to control the python population, and none of the available tools have been validated in the field to assess capture success as a proportion of pythons available to be captured. Aims. Our primary aim was to conduct a trap trial for capturing invasive pythons in an area east of Everglades National Park, where many pythons had been captured in previous years, to assess the efficacy of traps for population control.Wealso aimed to compare results of visual surveys with trap capture rates, to determine capture rates of non-target species, and to assess capture rates as a proportion of resident pythons in the study area. Methods.Weconducted a medium-scale (6053 trap nights) experiment using two types of attractant traps baited with live rats in the Frog Pond area east of Everglades National Park.Wealso conducted standardised and opportunistic visual surveys in the trapping area. Following the trap trial, the area was disc harrowed to expose pythons and allow calculation of an index of the number of resident pythons. Key results. We captured three pythons and 69 individuals of various rodent, amphibian, and reptile species in traps. Eleven pythons were discovered during disc harrowing operations, as were large numbers of rodents. Conclusions. The trap trial captured a relatively small proportion of the pythons that appeared to be present in the study area, although previous research suggests that trap capture rates improve with additional testing of alternative trap designs. Potential negative impacts to non-target species were minimal. Low python capture rates may have been associated with extremely high local prey abundances during the trap experiment. Implications. Results of this trial illustrate many of the challenges in implementing and interpreting results from tests of control tools for large cryptic predators such as Burmese pythons. ??

The direction and magnitude of future lake thermal responses will be driven largely by the extent of inlet stream migration when it occurs simultaneously with outlet erosion.

Recently, the working group to restudy the base of the Wenlock Series has developed an extremely high-resolution global chronostratigraphy for the Telychian and Sheinwoodian stages by integrating graptolite and conodont biostratigraphy with carbonate carbon isotope (??13Ccarb) chemostratigraphy. This improved global chronostratigraphy has required such significant chronostratigraphic revisions to the North American succession that much of the Silurian System in North America is currently in a state of flux and needs further refinement. This report serves as an update of the progress on recalibrating the global chronostratigraphic correlation of North American Provincial Series and Stage boundaries in their type area. The revised North American classification is correlated with global series and stages as well as regional classifications used in the United Kingdom, the East Baltic, Australia, China, the Barrandian, and Altaj. Twenty-four potential stage slices, based primarily on graptolite and conodont zones and correlated to the global series and stages, are illustrated alongside a new composite ??13Ccarb curve for the Silurian.

This study investigates the use of modeling techniques to quantitatively examine rates of coral cover change due to these effects. Methodology/Principal Findings: Broad-scale probabilities of change in shallow-water scleractinian coral cover in the Hawaiian Archipelago for years 2000-2099 A.D. were calculated assuming a single middle-of-the-road greenhouse gas emissions scenario. These projections were based on ensemble calculations of a growth and mortality model that used sea surface temperature (SST), atmospheric carbon dioxide (CO2), observed coral growth (calcification) rates, and observed mortality linked to mass coral bleaching episodes as inputs. SST and CO2 predictions were derived from the World Climate Research Programme (WCRP) multi-model dataset, statistically downscaled with historical data. Conclusions/Significance: The model calculations illustrate a practical approach to systematic evaluation of climate change effects on corals, and also show the effect of uncertainties in current climate predictions and in coral adaptation capabilities on estimated changes in coral cover. Despite these large uncertainties, this analysis quantitatively illustrates that a large decline in coral cover is highly likely in the 21st Century, but that there are significant spatial and temporal variances in outcomes, even under a single climate change scenario.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"PLoS ONE","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1371/journal.pone.0018038","issn":"19326203","usgsCitation":"Hoeke, R., Jokiel, P., Buddemeier, R., and Brainard, R., 2011, Projected changes to growth and mortality of Hawaiian corals over the next 100 years: PLoS ONE, v. 6, no. 3, https://doi.org/10.1371/journal.pone.0018038.","costCenters":[],"links":[{"id":487162,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0018038","text":"Publisher Index Page"},{"id":244601,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216715,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1371/journal.pone.0018038"}],"volume":"6","issue":"3","noUsgsAuthors":false,"publicationDate":"2011-03-29","publicationStatus":"PW","scienceBaseUri":"505a8eefe4b0c8380cd7f4a0","contributors":{"authors":[{"text":"Hoeke, R.K.","contributorId":26544,"corporation":false,"usgs":true,"family":"Hoeke","given":"R.K.","email":"","affiliations":[],"preferred":false,"id":443690,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jokiel, P.

In order to explain these changes, a number of hypotheses have been given, among which thermoelastic and hydrology-induced stresses and strains are leading candidates. Unfortunately, though, since a general framework does not exist for understanding such seasonal variations, it is currently not possible to quickly evaluate the plausibility of these hypotheses. To fill this gap in the literature, I generalize a two-dimensional thermoelastic strain model to provide an analytic solution for the displacements and wave speed changes due to either thermoelastic stresses or hydrologic loading, which consists of poroelastic stresses and purely elastic stresses. The thermoelastic model assumes a periodic surface temperature, and the hydrologic models similarly assume a periodic near-surface water load. Since all three models are two-dimensional and periodic, they are expected to only approximate any realistic scenario; but the models nonetheless provide a quantitative framework for estimating the effects of thermoelastic and hydrologic variations. Quantitative comparison between the models and observations is further complicated by the large uncertainty in some of the relevant parameters. Despite this uncertainty, though, I find that maximum realistic thermoelastic effects are unlikely to explain a large fraction of the observed annual variation in a typical GPS displacement time series or of the observed annual variations in seismic wave speeds in southern California. Hydrologic loading, on the other hand, may be able to explain a larger fraction of both the annual variations in displacements and seismic wave speeds. Neither model is likely to explain all of the seismic wave speed variations inferred from observations. However, more definitive conclusions cannot be made until the model parameters are better constrained.

We have combined measured (or estimated) observations from the DH release with empirical relationships developed from previous lab experiments to identify the mechanisms responsible for intrusion formation and to characterize the DH plume. Results indicate that the intrusions originate from a stratification-dominated multiphase plume characterized by multiple subsurface intrusions containing dissolved gas and oil along with small droplets of liquid oil. Unlike earlier lab measurements, where the potential density in ambient water decreased linearly with elevation, at the DH site it varied quadratically. We have modified our method for estimating intrusion elevation under these conditions and the resulting estimates agree with observations that the majority of the hydrocarbons were found between 800 and 1200 m.

River to the Itaipu Reservoir along the Brazil-Paraguay border. The canal was constructed to allow migratory fishes to reach suitable habitats for reproduction and feeding in tributaries upstream from the reservoir. The Piracema Canal attracted 17 of the 19 long-distance migratory species that have been recorded in the Paran?? River Basin and Paraguay-Paran?? Basin. However, the incidence of migratory fish decreased from downstream to upstream, with the pattern of decrease depending on species. Overall, 0.5% of the migratory fish that entered the Piracema Canal and segment 1, eventually were able to reach segment 5 and potentially Itaipu Reservoir. Ascension rate was examined relative to various physical attributes of canal segments; maximum water velocity emerged as the most influential variable affecting fish passage. Water velocity may be manipulated by controlling water discharge, and by re-engineering critical sections of the canal. Because the Itaipu Reservoir flooded a set of falls that separated two distinct biogeographical regions, facilitating fish movements through the Piracema Canal into the Itaipu Reservoir presents a management dilemma that requires deliberation in the context of the fish assemblages rather than on selected migratory species. ?? 2010 John Wiley & Sons, Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"River Research and Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/rra.1378","issn":"15351459","usgsCitation":"Makrakis, S., Miranda, L., Gomes, L., Makrakis, M., and Junior, H., 2011, Ascent of neotropical migratory fish in the Itaipu Reservoir fish pass: River Research and Applications, v. 27, no. 4, p. 511-519, https://doi.org/10.1002/rra.1378.","startPage":"511","endPage":"519","numberOfPages":"9","costCenters":[],"links":[{"id":216807,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/rra.1378"},{"id":244699,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"27","issue":"4","noUsgsAuthors":false,"publicationDate":"2011-05-05","publicationStatus":"PW","scienceBaseUri":"5059edb6e4b0c8380cd49972","contributors":{"authors":[{"text":"Makrakis, S.","contributorId":49592,"corporation":false,"usgs":true,"family":"Makrakis","given":"S.","email":"","affiliations":[],"preferred":false,"id":443445,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Miranda, L.E.","contributorId":58406,"corporation":false,"usgs":true,"family":"Miranda","given":"L.E.","affiliations":[],"preferred":false,"id":443446,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gomes, L.C.","contributorId":7108,"corporation":false,"usgs":true,"family":"Gomes","given":"L.C.","email":"","affiliations":[],"preferred":false,"id":443444,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Makrakis, M.C.","contributorId":73406,"corporation":false,"usgs":true,"family":"Makrakis","given":"M.C.","email":"","affiliations":[],"preferred":false,"id":443447,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Junior, H.M.F.","contributorId":79335,"corporation":false,"usgs":true,"family":"Junior","given":"H.M.F.","email":"","affiliations":[],"preferred":false,"id":443448,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The depth-averaged shallow water equations can be used to reduce this to a time-dependent problem in two space dimensions, but even so it is crucial to use adaptive mesh refinement in order to efficiently handle the vast differences in spatial scales. This must be done in a 'wellbalanced' manner that accurately captures very small perturbations to the steady state of the ocean at rest. Inundation can be modelled by allowing cells to dynamically change from dry to wet, but this must also be done carefully near refinement boundaries. We discuss these issues in the context of Riemann-solver-based finite volume methods for tsunami modelling.

Concentrations of suspended sediment in runoff were statistically greater using a fixed rather than multipoint collection system. Median suspended sediment concentrations measured at the fixed location (near the pipe invert) were approximately double those collected using the DISA. In general, concentrations and size distributions of suspended sediment decreased with increasing vertical distance from the storm sewer invert. Coarser particles tended to dominate the distribution of solids near the storm sewer invert as discharge increased. In contrast to concentration and particle size, organic material, to some extent, was distributed homogenously throughout the water column, likely the result of its low specific density, which allows for thorough mixing in less turbulent water. ?? 2010 Publishing Technology.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Water Environment Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2175/106143010X12851009156006","issn":"10614303","usgsCitation":"Selbig, W., and Bannerman, R., 2011, Development of a depth-integrated sample arm to reduce solids stratification bias in stormwater sampling: Water Environment Research, v. 83, no. 4, p. 347-357, https://doi.org/10.2175/106143010X12851009156006.","startPage":"347","endPage":"357","numberOfPages":"11","costCenters":[],"links":[{"id":214448,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2175/106143010X12851009156006"},{"id":242176,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"83","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0038e4b0c8380cd4f64a","contributors":{"authors":[{"text":"Selbig, W.R.","contributorId":102106,"corporation":false,"usgs":true,"family":"Selbig","given":"W.R.","email":"","affiliations":[],"preferred":false,"id":443295,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bannerman, R.T.","contributorId":92304,"corporation":false,"usgs":false,"family":"Bannerman","given":"R.T.","email":"","affiliations":[{"id":6913,"text":"Wisconsin Department of Natural Resources","active":true,"usgs":false}],"preferred":false,"id":443294,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The ultramafic rocks in this region are comprised mainly of serpentinites and talc-magnesite rocks with average As concentration of 93ppm and a range from 1 to 1105ppm. By comparison, the other main lithologies in the study area are depleted in As relative to the ultramafics: the average As concentration in metabasaltic rocks is 4.1ppm with a range of &lt;1-69ppm, and mean As concentration in meta-sedimentary phyllites and schists is 22ppm with a range of &lt;1-190ppm. In the ultramafic rocks, As is correlated with Sb and light rare earth elements, indicating that As was introduced to the ultramafic rocks during metasomatism by fluids derived from the subducting slab. Evidence from sequential chemical extraction, X-ray diffraction (XRD) and stoichiometric analysis indicates that the majority of the As is located in antigorite and magnesite (MgCO3) with lesser amounts in magnetite (Fe3O4). Hydrochemistry of monitoring wells drilled into fractured ultramafic rock in a groundwater recharge area with no anthropogenic As source reveals above background As (2-9??g/L) and an Mg-HCO3 hydrochemical signature that reflects dissolution of antigorite and magnesite, confirming that As in groundwater can be derived from ultramafic rock dissolution. Arsenic mobility in groundwater affected by ultramafic rock dissolution may be enhanced by alkaline pH values and relatively high HCO3- concentrations. ?? 2011 Elsevier Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied Geochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.apgeochem.2011.01.004","issn":"08832927","usgsCitation":"Ryan, P., Kim, J., Wall, A., Moen, J., Corenthal, L., Chow, D., Sullivan, C., and Bright, K., 2011, Ultramafic-derived arsenic in a fractured bedrock aquifer: Applied Geochemistry, v. 26, no. 4, p. 444-457, https://doi.org/10.1016/j.apgeochem.2011.01.004.","startPage":"444","endPage":"457","numberOfPages":"14","costCenters":[],"links":[{"id":214328,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.apgeochem.2011.01.004"},{"id":242045,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbc02e4b08c986b32898c","contributors":{"authors":[{"text":"Ryan, P.C.","contributorId":10240,"corporation":false,"usgs":true,"family":"Ryan","given":"P.C.","email":"","affiliations":[],"preferred":false,"id":443238,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kim, J.","contributorId":9813,"corporation":false,"usgs":true,"family":"Kim","given":"J.","email":"","affiliations":[],"preferred":false,"id":443237,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wall, A.J.","contributorId":8686,"corporation":false,"usgs":true,"family":"Wall","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":443236,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Moen, J.C.","contributorId":53181,"corporation":false,"usgs":true,"family":"Moen","given":"J.C.","email":"","affiliations":[],"preferred":false,"id":443240,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Corenthal, L.G.","contributorId":61658,"corporation":false,"usgs":true,"family":"Corenthal","given":"L.G.","email":"","affiliations":[],"preferred":false,"id":443242,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Chow, D.R.","contributorId":62847,"corporation":false,"usgs":true,"family":"Chow","given":"D.R.","email":"","affiliations":[],"preferred":false,"id":443243,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Sullivan, C.M.","contributorId":26530,"corporation":false,"usgs":true,"family":"Sullivan","given":"C.M.","email":"","affiliations":[],"preferred":false,"id":443239,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Bright, K.S.","contributorId":55222,"corporation":false,"usgs":true,"family":"Bright","given":"K.S.","email":"","affiliations":[],"preferred":false,"id":443241,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Damaging large aftershocks occur close to the mainshock and microearthquakes are triggered by passing seismic waves at significant distances from the mainshock. It is unclear, however, whether bigger, more damaging earthquakes are routinely triggered at distances far from the mainshock, heightening the global seismic hazard after every large earthquake. Here we assemble a catalogue of all possible earthquakes greater than M 5 that might have been triggered by every M 7 or larger mainshock during the past 30 years. We compare the timing of earthquakes greater than M 5 with the temporal and spatial passage of surface waves generated by large earthquakes using a complete worldwide catalogue. Whereas small earthquakes are triggered immediately during the passage of surface waves at all spatial ranges, we find no significant temporal association between surface-wave arrivals and larger earthquakes. We observe a significant increase in the rate of seismic activity at distances confined to within two to three rupture lengths of the mainshock. Thus, we conclude that the regional hazard of larger earthquakes is increased after a mainshock, but the global hazard is not.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Nature Geoscience","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Nature Publishing Group","publisherLocation":"London, U.K.","doi":"10.1038/ngeo1110","issn":"17520894","usgsCitation":"Parsons, T., and Velasco, A., 2011, Absence of remotely triggered large earthquakes beyond the mainshock region: Nature Geoscience, v. 4, no. 5, p. 312-316, https://doi.org/10.1038/ngeo1110.","productDescription":"5 p.","startPage":"312","endPage":"316","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":214302,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1038/ngeo1110"},{"id":242010,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4","issue":"5","noUsgsAuthors":false,"publicationDate":"2011-03-27","publicationStatus":"PW","scienceBaseUri":"5059e649e4b0c8380cd472fe","contributors":{"authors":[{"text":"Parsons, T.","contributorId":48288,"corporation":false,"usgs":true,"family":"Parsons","given":"T.","email":"","affiliations":[],"preferred":false,"id":443230,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Velasco, A.A.","contributorId":101894,"corporation":false,"usgs":true,"family":"Velasco","given":"A.A.","email":"","affiliations":[],"preferred":false,"id":443231,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The plots showed distinct patterns in fish habitat suitability at each level of biological organization studied and were useful for quantitatively comparing river sites. We demonstrate how these plots can be used to support stream management, and we provide examples pertaining to resource assessment, trout stocking, angling regulations, chemical reclamation of marginal trout streams, indicator species, instream flow protection, and habitat restoration.

Direct or indirect measurements of surface water resources through remote sensing offer several advantages of monitoring in ungauged basins. A physical based hydrologic technique to monitor lake water levels in ungauged basins using multi-source satellite data such as satellite-based rainfall estimates, modelled runoff, evapotranspiration, a digital elevation model, and other data is presented. This approach is applied to model Lake Turkana water levels from 1998 to 2009. Modelling results showed that the model can reasonably capture all the patterns and seasonal variations of the lake water level fluctuations. A composite lake level product of TOPEX/Poseidon, Jason-1, and ENVISAT satellite altimetry data is used for model calibration (1998-2000) and model validation (2001-2009). Validation results showed that model-based lake levels are in good agreement with observed satellite altimetry data. Compared to satellite altimetry data, the Pearson's correlation coefficient was found to be 0.81 during the validation period. The model efficiency estimated using NSCE is found to be 0.93, 0.55 and 0.66 for calibration, validation and combined periods, respectively. Further, the model-based estimates showed a root mean square error of 0.62 m and mean absolute error of 0.46 m with a positive mean bias error of 0.36 m for the validation period (2001-2009). These error estimates were found to be less than 15 % of the natural variability of the lake, thus giving high confidence on the modelled lake level estimates. The approach presented in this paper can be used to (a) simulate patterns of lake water level variations in data scarce regions, (b) operationally monitor lake water levels in ungauged basins, (c) derive historical lake level information using satellite rainfall and evapotranspiration data, and (d) augment the information provided by the satellite altimetry systems on changes in lake water levels. ??

However, wave exposure remains difficult and expensive to measure. Here, we report on an inexpensive and easily constructed instrument for measuring wave-induced water velocities. The underwater relative swell kinetics instrument (URSKI) is a subsurface float tethered by a short (<1 m) line to the seafloor. Contained within the float is an accelerometer that records the tilt of the float in response to passing waves. During two field trials totaling 358 h, we confirmed the accuracy and precision of URSKI measurements through comparison to velocities measured by an in situ acoustic Doppler velocimeter and those predicted by a standard swell model, and we evaluated how the dimensions of the devices, its buoyancy, and sampling frequency can be modified for use in a variety of environments.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Limnology and Oceanography: Methods","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.4319/lom.2011.9.204","issn":"15415856","usgsCitation":"Figurski, J., Malone, D., Lacy, J., and Denny, M., 2011, An inexpensive instrument for measuring wave exposure and water velocity: Limnology and Oceanography: Methods, v. 9, no.
