  3. Analysis of Landsat TM data for active tectonics: the case of the Big Chino Fault, Arizona

    Salvi, Stefano

    1994-12-01

    The Big Chino Valley is a 50 km-long tectonic depression of the Basin and Range province of the South- western United States. It is bordered on the NE side by an important normal fault, the Big Chino Fault. The activity of the latter has been hypothesised on the basis of the presence of a 20 m-high fault scarp and on local geomorphological studies. Moreover, a magnitude 4.9 earthquake occurred in southern Arizona in 1976 has been attributed to this fault. The climate in the Big Chino Valley is semi-arid with average rainfall of about 400 mm per year; a very sparse vegetation cover is present, yielding a good possibility for the geo-lithologic application of remote sensing data. The analysis of the TM spectral bands shows, in the short wave infrared, a clear variation in the reflected radiance across the fault scarp. Also the available radar (SLAR) images show a marked difference in response between the two sides of the fault. An explanation of this phenomena has been found in the interaction between the geomorphic evolution, the pedological composition, and the periodic occurrence of coseismic deformation along the fault. Other effects of the latter process have been investigated on colour D- stretched images whose interpretation allowed to detect two paleoseismic events of the Big Chino Fault. This work demonstrates that important information on the seismological parameters of active faults in arid and semiarid climates can be extracted from the analysis of satellite spectral data in the visible and near -infrared.

    French, James J.

    1972-01-01

    Ground-water outflow from Chino basin was calculated ,by a direct method using the equation Q = PIA, in which Q is the quantity of ground-water outflow, P is the average coefficient of permeability of the sediments through which the flow occurs, I is the average hydraulic gradient, and A is the cross-sectional area of the sediments through which the flow occurs. The period selected for the calculation was 1930-66. Permeability of the water-bearing sediments was calculated from aquifer test data and from computations involving specific-capacity data from 200 wells in the outflow area. Permeability ranged from less than 100 to more than 5,000 gallons per day per square foot. The annual hydraulic gradient was derived from contour maps of average water levels in wells for each water year for the period 1930-66. The cross-sectional area used to calculate ground-water outflow from Chino basin extends southwestward from Pedley Hills to Puente Hills. The area of the outflow section is the saturated thickness of permeable materials measured along the line of section. Part of the lower boundary is the interface between the alluvium and the underlying basement complex, and part is a change in permeability within sedimentary rocks. Geological methods were combined with geophysical methods to determine the cross-sectional area of the water-bearing sediments. Gravity and seismic traverses, drill-hole logs, and data from a more than 600 drill holes, including eight test holes drilled as a part of this investigation, were used to delineate the size and the shape of the outflow area. For the period of calculation, 1930-66, the total area of the outflow section varied from about 16 to 22 million square feet. The fluctuation in total area is caused by changes in the altitude of the water table. Annual ground-water outflow from Chino basin calculated by the direct method for the period 1930-66 ranged from 38,000 acre-feet in the 1941 water year to 9,400 acre-feet in the 1966 water

  5. Right to use groundwater in Arizona after Chino Valley II and Cherry vs Steiner

    Two cases which upheld Groundwater Code provisions are reviewed, Chino Valley II and Cherry vs Steiner. Arizona law regarding private rights in groundwater and the state's police power authority to limit those rights are also considered. The possibility of constitutional protection for already-exercised rights to use groundwater is explored through a discussion of decisions in other jurisdictions, and statements are made which indicate that Arizona will follow those decisions. It is thought that state-mandated conservation measures would provide adequate regulation of police-powered regulation of private interests. 158 references.

    2012-01-01

    Three different geophysical methods (magnetic, transient electromagnetic (TEM) and gravity) were used near Chino Valley, Arizona, USA in order to map a suspected lati-andesite intrusive body (plug) previously located by interpretation of aeromagnetic data. The magnetic and TEM surveys provided the best indication of the location and depth of the plug. The north-south spatial extent of this plug was estimated to be approximately 600 meters. The depth to the top of the plug was found from the TEM survey to be approximately 350 meters near the center of the survey. The location of the plug defined by the ground magnetic data is consistent with that from the TEM data. Gravity data mostly image the basin-basement interface with a small contribution from the plug of about 0.5 mGal. Results from this investigation can be used to help define the irregular subsurface topography caused by several intrusive lati-andesite plugs that could influence groundwater flow in the area.

    The 26.7--23.4 Ma Sullivan Buttes Latite of Chino Valley, Yavapai County, Arizona, erupted during the development of the Transition Zone between the Basin and Range and Colorado Plateau provinces. Detailed mapping and stratigraphic analysis of a portion of the volcanic field indicate volcanism began with the eruption of a shoshonite lava flow and associated cinder cone. Amphibole latite domes then erupted fallouts, surges, and mass flow breccias and culminated activity with a lava flow. Extrusive units from a biotite oxidized latite center to the east interfinger with the older amphibole lattice volcaniclastics. Sullivan Buttes Latite units erupted onto Precambrian and lower Paleozoic strata and Tertiary gravels; the scarp of upper Paleozoic strata equivalent to the paleo' Mogollon Rim had retreated from the area by the time of emplacement of the oldest Sullivan Buttes Latite unit. Subsequent 15--10 Ma Hickey Formation basalts flowed onto an erosion surface cut into Sullivan Buttes deposits, and the nearby Verde River downcut through younger 4.62 Ma Perkinsville Formation basalt. Both situations demonstrate erosion and degradation post Sullivan Buttes activity. Normal faults offsetting Hickey Formation basalts and all older units constrain Basin and Range structural activity to 15 Ma or younger. These stratigraphic relationships of the Sullivan Buttes Latite in the context of Transition Zone development concur with 65--18 Ma retreat of the upper Paleozoic scarp and below-scarp aggradation, 18--12 Ma Basin and Range faulting, and subsequent degradation.

    In Puerto Rico and Cuba, the phrase "can't be saved even by the Chinese physician" ("no lo salva ni el médico chino") indicates a person with an incurable disease. The documents at the Archivo General de Puerto Rico include three requests for a medical license from a Chinese immigrant, Juan de Dios Sian (Lin Hua Cheng). Despite lacking legal credentials, he used herbal therapies to treat chronically ill persons in Ponce, San Juan and Mayaguez from 1851 to 1853. Before arriving in Ponce he had spent four years in Cuba, where he is again found by 1865. Sian's petitions show that Puerto Rico, like Cuba, experienced a widely known "médico chino." The anecdote reminds us of important issues in our medical and social history: Asiatic immigration (earlier, larger and more diverse than usually considered), access to care (and its limitations), and the long history of herbal medicine in Oriental and Western cultures. Elements of this story, such as the eagerness for new treatments among patients who have derived no benefit from standard therapy, the ethics of medical licensing, the impotence of licensing agencies and the toleration of authorities regarding an unorthodox but popular healer, exemplify dilemmas that accompany medical practice at all times.

    The column-average dry air mole fractions of carbon dioxide (XCO2) and methane (XCH4) were measured with a portable Fourier transform spectrometer (FTS), EM27/SUN, using direct sunlight at 1) Caltech, in Pasadena, a northern Los Angeles suburb, 2) Chino, a dairy region east of Los Angeles, and 3) Railroad Valley (RRV), a desert playa in Nevada. They were conducted during the GOSAT/OCO-2 joint campaign for vicarious calibration and validation (cal/val) and its preparatory experiments in June-July 2015. JAXA's GOSAT has been operating since 2009 to monitor the greenhouse gases XCO2 and XCH4 using surface-reflected sunlight from space. GOSAT carries a Fourier Transform Spectrometer (TANSO-FTS) and a Cloud and Aerosol Imager (TANSO-CAI). NASA's OCO-2 has been operating since 2014, carries a grating spectrometer to make precise XCO2 observations with a-few-kilometer resolution. Their polar orbits have 12:46 pm (GOSAT) and 1:30 pm (OCO-2) observing times. For cal/val, these sites were targeted with coincident , near simultaneous ground-based and vertical profiling measurements. These sites are different types of suburban, dairy, and desert areas. Before the campaign, measurements from the JAXA EM27/SUN were compared with those from the Total Carbon Column Observing Network (TCCON) and from the Caltech EM27/SUN at Pasadena. We compared the retrieved values and simultaneously observed diurnal enhancements by advection from the Los Angeles basin. Then, we observed a diurnal cycle at Chino dairy area, an area of concentrated husbandry, producing a CH4 point source. Finally, we conducted the cal/val campaign at RRV coincident with GOSAT and OCO-2 overpass observations. Over RRV, vertical profiles of CO2 and CH4 were measured using the Alpha Jet research aircraft as a part of the NASA Ames Alpha Jet Atmospheric eXperiment (AJAX) . We will compare experimental results from the cal/val campaign for XCO2 and XCH4 with a portable FTS.

  13. Application of a watershed model (HSPF) for evaluating sources and transport of pathogen indicators in the Chino Basin drainage area, San Bernardino County, California

    2011-01-01

    A watershed model using Hydrologic Simulation Program-FORTRAN (HSPF) was developed for the urbanized Chino Basin in southern California to simulate the transport of pathogen indicator bacteria, evaluate the flow-component and land-use contributions to bacteria contamination and water-quality degradation throughout the basin, and develop a better understanding of the potential effects of climate and land-use change on water quality. The calibration of the model for indicator bacteria was supported by historical data collected before this study and by samples collected by the U.S. Geological Survey from targeted land-use areas during storms in water-year 2004. The model was successfully calibrated for streamflow at 5 gage locations representing the Chino Creek and Mill Creek drainages. Although representing pathogens as dissolved constituents limits the model's ability to simulate the transport of pathogen indicator bacteria, the bacteria concentrations measured over the period 1998-2004 were well represented by the simulated concentrations for most locations. Hourly concentrations were more difficult to predict because of high variability in measured bacteria concentrations. In general, model simulations indicated that the residential and commercial land uses were the dominant sources for most of the pathogen indicator bacteria during low streamflows. However, simulations indicated that land used for intensive livestock (dairies and feedlots) and mixed agriculture contributed the most bacteria during storms. The calibrated model was used to evaluate how various land use, air temperature, and precipitation scenarios would affect flow and transport of bacteria. Results indicated that snow pack formation and melt were sensitive to changes in air temperature in the northern, mountainous part of the Chino Basin, causing the timing and magnitude of streamflow to shift in the natural drainages and impact the urbanized areas of the central Chino Basin.

Historical collections of the species, which prior to 2011 had not been seen alive in 94 years, have been misidentified as Calystegia sepium (L.) R. Br. subsp. binghamiae (Greene) Brummitt. The undescribed species was rediscovered in the City of Chino in April of 2011, a few miles north of the location where the most recent previous collection had been made by I. M. Johnston in 1917. The plants were found just prior to their likely destruction by grading and trenching for an underground power line. Intensive searches have resulted in the discovery of five additional occurrences, all of them in the City of Chino. Calystegia felix is at high risk of soon becoming extinct in the wild. All of the known extant occurrences are associated with well-watered landscaping on recently completed industrial, commercial, and residential developments. Every known living occurrence is within the limits of a ciénega belt, which is now mostly historical. Otherwise, the new species is only known only from collections made around the turn of the 20(th) century in what are now heavily urbanized areas, including one from South Los Angeles and another from Pico Rivera in Los Angeles County. Calystegia felix lacks the large bracts that immediately subtend, and enclose the calyx, which are always present in members of the Calystegia sepium complex. Affinities to Calystegia felix are found among other western US species with graduated sepals and small, often somewhat remote bracts. We discuss the enduring confusion between Calystegia felix and Calystegia sepium subsp. binghamiae, and differentiate the new species from some of its more likely relatives. The taxonomic treatment is supplemented by photos of herbarium specimens and living plants. We also discuss the ecological setting of Chino's ciénega belt, which was a mosaic of

    Despite the ever increasing availability of computational power, real-time source inversions based on physical modeling of wave propagation in realistic media remain challenging. We investigate how a nonlinear Bayesian approach based on pattern recognition and synthetic 3-D Green's functions can be used to rapidly invert strong-motion data for point source parameters by means of a case study for a fault system in the Los Angeles Basin. The probabilistic inverse mapping is represented in compact form by a neural network which yields probability distributions over source parameters. It can therefore be evaluated rapidly and with very moderate CPU and memory requirements. We present a simulated real-time inversion of data for the 2008 Mw 5.4 Chino Hills event. Initial estimates of epicentral location and magnitude are available ˜14 s after origin time. The estimate can be refined as more data arrive: by ˜40 s, fault strike and source depth can also be determined with relatively high certainty.

    2000-01-01

    This report summarizes the acquisition, data processing, and preliminary interpretation of a high-resolution aeromagnetic and radiometric survey near the confluence of the Big and Little Chino basins in the headwaters of the Verde River, Arizona. The goal of the aeromagnetic study is to improve understanding of the geologic framework as it affects groundwater flow, particularly in relation to the occurrence of springs in the upper Verde River headwaters region. Radiometric data were also collected to map surficial rocks and soils, thus aiding geologic mapping of the basin fill. Additional gravity data were collected to enhance existing coverage. Both aeromagnetic and gravity data indicate a large gradient along the Big Chino fault, a fault with Quaternary movement. Filtered aeromagnetic data show other possible faults within the basin fill and areas where volcanic rocks are shallowly buried. Gravity lows associated with Big Chino and Williamson Valleys indicate potentially significant accumulations of low-density basin fill. The absence of a gravity low associated with Little Chino Valley indicates that high-density rocks are shallow. The radiometric maps show higher radioactivity associated with the Tertiary latites and with the sediments derived from them. The surficial materials on the eastern side of the Big Chino Valley are significantly lower in radioactivity and reflect the materials derived from the limestone and basalt east of the valley. The dividing line between the low radioactivity materials to the east and the higher radioactiviy materials to the west coincides approximately with the major drainage system of the valley, locally known as Big Chino Wash. This feature is remarkably straight and is approximately parallel to the Big Chino Fault. The uranium map shows large areas with concentrations greater than 5 ppm eU, and we expect that these areas will have a significantly higher risk potential for indoor radon.

Métodos: En mayo y octubre de 2013, se recopilaron aleatoriamente un total de 328 muestras fecales de caimanes chinos en cautividad de un centro de cría en el sur de la provincia de Anhui. Resultados: Fueron identificados tres géneros de protozoos (Entaoeba, Eimeria e Isospora), cinco géneros de nematodos (Ascaris, Dujardin Ascaris, Capillaria, Toxocara y Strongylus), dos géneros de trematodos (Echinostoma y Clonorchis) y dos familias de trematodos (Schistosomatidae y Cryptogonimidae), de los cuales la mayor prevalencia correspondió a Dujardin Ascaris y producían la mayor tasa de infección (14,33%); entaoeba se situó en el segundo puesto (13,11%). El número de especies, índice de riqueza, índice de diversidad y de equitatividad fue superior en los meses de julio y agosto, y éstos, relativamente más para caimanes jóvenes y sub-adultos. Conclusiones: Nuestros resultados apuntan la prevalencia de la infección por parásitos intestinales en caimanes chinos en cautividad y ello exige nuestra atención, ya sea para controlar o prevenir la propagación de la enfermedad parasitaria intestinal a los seres humanos, o para la conservación de esta especie en peligro de extinción.

    Perchlorate from military, industrial, and legacy agricultural sources is present within an alluvial aquifer in the Rialto-Colton groundwater subbasin, 80 km east of Los Angeles, California (USA). The area is extensively faulted, with water-level differences exceeding 60 m across parts of the Rialto-Colton Fault separating the Rialto-Colton and Chino groundwater subbasins. Coupled well-bore flow and depth-dependent water-quality data show decreases in well yield and changes in water chemistry and isotopic composition, reflecting changing aquifer properties and groundwater recharge sources with depth. Perchlorate movement through some wells under unpumped conditions from shallower to deeper layers underlying mapped plumes was as high as 13 kg/year. Water-level maps suggest potential groundwater movement across the Rialto-Colton Fault through an overlying perched aquifer. Upward flow through a well in the Chino subbasin near the Rialto-Colton Fault suggests potential groundwater movement across the fault through permeable layers within partly consolidated deposits at depth. Although potentially important locally, movement of groundwater from the Rialto-Colton subbasin has not resulted in widespread occurrence of perchlorate within the Chino subbasin. Nitrate and perchlorate concentrations at the water table, associated with legacy agricultural fertilizer use, may be underestimated by data from long-screened wells that mix water from different depths within the aquifer.

    Stable isotope delta values (δ18O and δ2H) of precipitation can vary with elevation, and quantification of the precipitation elevation gradient can be used to predict recharge elevation within a watershed. Precipitation samples were analyzed for stable isotope delta values between 2003 and 2014 from the Verde River watershed of north-central Arizona. Results indicate a significant decrease in summer isotopic values overtime at 3,100-, 4,100-, 6,100-, 7,100-, and 8,100-feet elevation. The updated local meteoric water line for the area is δ2H = 7.11 δ18O + 3.40. Equations to predict stable isotopic values based on elevation were updated from previous publications in Blasch and others (2006), Blasch and Bryson (2007), and Bryson and others (2007). New equations were separated for samples from the Camp Verde to Flagstaff transect and the Prescott to Chino Valley transect. For the Camp Verde to Flagstaff transect, the new equations for winter precipitation are δ18O = -0.0004z − 8.87 and δ2H = -0.0029z − 59.8 (where z represents elevation in feet) and the summer precipitation equations were not statistically significant. For the Prescott to Chino Valley transect, the new equations for summer precipitation are δ18O = -0.0005z − 3.22 and δ2H = -0.0022z − 27.9; the winter precipitation equations were not statistically significant and, notably, stable isotope values were similar across all elevations. Interpretation of elevation of recharge contributing to surface and groundwaters in the Verde River watershed using the updated equations for the Camp Verde to Flagstaff transect will give lower elevation values compared with interpretations presented in the previous studies. For waters in the Prescott and Chino Valley area, more information is needed to understand local controls on stable isotope values related to elevation.

    The pleasure oyster Crassostrea corteziensis is collected and cultured in Nayarit on the Pacific coast of Mexico, and the improvement and promotion of its culture are seen as a possible source for the economic development of coastal populations. However, information about the parasite fauna of the pleasure oyster is almost completely lacking. A histopathological survey carried out in two estuaries, Boca del Camichín and Pozo Chino, revealed the presence of hypertrophied gametes, rickettsiales-like prokaryotes (RLPs), the protozoan Perkinsus marinus, a protozoan Nematopsis sp., Ancistrocoma-like ciliates (ALCs), Sphenophrya-like ciliates, a turbellarian Urastoma sp., and encysted crustaceans. In general, prevalence and intensity of parasites were similar in both localities except that ALCs and encysted crustaceans were more prevalent in Pozo Chino than in Boca del Camichín. Perkinsus marinus and RLPs seem to represent a more significant risk for the health of pleasure oysters than do the other parasites, and surveillance and control of these parasites are needed for the development of pleasure oyster culture.

  17. Distinguishing sources of groundwater nitrate by 1H NMR of dissolved organic matter.

    Dissolved organic matter (DOM) originating from a certain source usually carries characteristic marks in its molecular structures that can be recognized by spectroscopic analysis. Sources of water-borne contaminants, such as nitrate, can be identified by recognition of the characteristics of DOM entrained in the water. In this study, DOM in groundwaters sampled from a dairy/crop production area (Chino Basin, CA) was analyzed by 1H nuclear magnetic resonance (1H NMR). Results showed that DOM derived from natural soil organic matter has a characteristic resonance at a chemical shift region of 4.0-4.3 ppm, while DOM derived from dairy wastes has a characteristic resonance at a lower chemical shift region of 3.2-3.6 ppm. These signature resonances were then used to distinguish the origins of nitrate in the groundwater. It was found that disposal of dairy wastes on croplands is the primary source of nitrate contamination in groundwater underlying the Chino Basin dairy area.

  18. Rapid probabilistic source characterisation in 3D earth models using learning algorithms

    Characterising earthquake sources rapidly and robustly is an essential component of any earthquake early warning (EEW) procedure. Ideally, this characterisation should:(i) be probabilistic -- enabling appreciation of the full range of mechanisms compatible with available data, and taking observational and theoretical uncertainties into account; and(ii) operate in a physically-complete theoretical framework.However, implementing either of these ideals increases computational costs significantly, making it unfeasible to satisfy both in the short timescales necessary for EEW applications.The barrier here arises from the fact that conventional probabilistic inversion techniques involve running many thousands of forward simulations after data has been obtained---a procedure known as `posterior sampling'. Thus, for EEW, all computational costs must be incurred after the event time. Here, we demonstrate a new approach---based instead on `prior sampling'---which circumvents this problem and is feasible for EEW applications. All forward simulations are conducted in advance, and a learning algorithm is used to assimilate information about the relationship between model and data. Once observations from an earthquake become available, this information can be used to infer probability density functions (pdfs) for seismic source parameters, within milliseconds.We demonstrate this procedure using data from the 2008 Mw5.4 Chino Hills earthquake. We compute Green's functions for 150 randomly-chosen locations on the Whittier and Chino faults, using SPECFEM3D and a 3D model of the regional velocity structure. We then use these to train neural networks that map from seismic waveforms to pdfs on a point-source, moment-tensor representation of the event mechanism. We show that using local network data from the Chino Hills event, this system provides accurate information on magnitude, epicentral location and source half-duration using data available 6 seconds after the first station

    Since May 1970, personnel on several campuses of the University of California have been conducting investigations which seek to determine the usefulness of modern remote sensing techniques for studying various components of California's earth resources complex. Emphasis has been given to California's water resources as exemplified by the Feather River project and other aspects of the California Water Plan. This study is designed to consider in detail the supply, demand, and impact relationships. The specific geographic areas studied are the Feather River drainage in northern California, the Chino-Riverside Basin and Imperial Valley areas in southern California, and selected portions of the west side of San Joaquin Valley in central California. An analysis is also given on how an effective benefit-cost study of remote sensing in relation to California's water resources might best be made.

    Individuals of Spanish and Mexican descent in New Mexico have used a number of plants as emmenagogues and abortifacients. Of the plants used, cotton root bark (Gossypium sp.), inmortal ((Asclepias capricornu Woodson), poleo chino (Hedeoma oblongifolia (Gray) Heller), rue Ruta graveolens L.), wormseed (Chenopodium ambrosioides L.), and three species of Artemesia seem to be used most widely. Of these, the cotton root bark, when used as an abortifacient, seems to exhibit the lowest toxicity. Rue is notable because of its use independently within different cultures, but may exhibit toxic side effects when used as an abortifacient. Seven other plants are outlined on the basis of anecdotal and folkloric reports. Investigations are underway to look at use effectiveness, side effects, impact on fertility, and acceptance among cultures of the Southwestern United States.

    The areas of focus of the Santa Barbara and Riverside groups in conducting water demand studies are the central and southern California regional test sites, respectively. Within each test site, sub-areas have been selected for use in the making of detailed investigations. Within each of these sub-areas an in-depth evaluation is being made as to the capability of remote sensing systems to provide pertinent data relative to water demand phenomena. These more limited sub-areas are: (1) Kern County and the San Joaquin Basin; (2) Chino-Riverside Basin; and (3) the Imperial Valley. Rational for the selection of these subareas included the following: Much of the previous remote sensing research had been conducted in these areas and therefore a great deal of remote sensing imagery and pertinent ground truth for the areas was already available.

    A method for the determination of the temperature distribution in the range from 1300 °C to 2500°C is introduced in this paper. This method was adapted to characterize the two high temperature furnaces used at LNE-Cnam: the Chino IR-R80 and the VNIIOFI HTBB 3200pg. Temperature profiles are given at three furnace temperatures, corresponding to the three most studied metal-carbon eutectic points: Co-C (1324 °C), Pt-C (1738 °C) and Re-C (2474 °C). These three fixed points were then studied in the two furnaces in different known temperature profiles, in order to determine their sensitivity to the temperature distribution. Finally, a discussion on what can be included in the term "furnace effect" is proposed.

    The GOSAT-COMEX-IASI (Greenhouse gases Observing SATellite - CO2 and Methane EXperiment - Infrared Atmospheric Sounding Interferometer) experiment acquired data on 24-27 April 2015 with two aircraft, a mobile ground-based sampling suite, and the GOSAT and IASI platforms. Collections comprised the Kern Front and Kern River oil fields north of Bakersfield, Calif. and the Chino stockyard complex in the eastern Los Angeles Basin. The nested-grid experiment examined the convergence of multiple approaches to total trace gas flux estimation from the experimental area on multiple length-scales, which entailed the integrated analysis of ground-based, airborne, and space-based measurements. Airborne remote sensing was employed to map the spatial distribution of discrete emission sites - crucial information to understanding their relative aggregate contribution to the overall flux estimation. This contribution discusses the methodology in the context of the airborne GHG source mapping component of the GOSAT-COMEX experiment and its application to satellite validation.

  6. Characterization of elastic and inelastic aquifer motion from satellite geodetic measurements

    NASA Astrophysics Data System (ADS)

    Bawden, G. W.

    2005-05-01

    The production of ground water in confined aquifer systems often results in a land- surface motion that is in a gradient between two end-member models--elastic deformation and inelastic deformation--that is directly measurable by satellite-based geodetic techniques. Elastic deformation is manifested by seasonal motion associated with the pumping, but with no permanent deformation; inelastic deformation results from permanent compaction of the fine-grained units and unrecoverable subsidence of the land surface. The combination of InSAR imagery, GPS measurements, and water-levels for Salt Lake City, UT, Chino Basin, CA and the metropolitan Los Angeles-Santa Ana region, CA, are used to characterize the end-member models and a hybrid model to show how aquifers respond to ground-water pumping stresses. In Salt Lake City, ground-water pumping results in a strong seasonal motion of as much as 85 mm that is not associated with any measurable long-term subsidence signal. Conversely the Chino Basin is subsiding at a rate of 34 mm/yr from ground-water pumping, with little seasonal motion. In the Los Angeles-Santa Ana region there is both elastic and inelastic motion, with greater than 60 mm of seasonal motion associated with 20 mm/year of subsidence. The inelastic subsidence began in 1995 and has been associated with a change in ground-water pumping policy. Improved characterization of these aquifer systems, and associated subsidence, may result in more effective approaches to ground-water resource management.

    450 ms, une plus grande négativité (N360) fut observée pour les pseudo-caractères comparativement aux caractères des régions du scalp au-dessus des régions médianes fronto-centrales. L'analyse dipôle a localisé le générateur de N360 dans le cortex para-hippocampique droit. Ainsi, le N360 pourrait être une composante N400 et refléter une activation sémantique de haut niveau sur la base des traitements orthographique, phonologique et perceptuel-sémantique. La mayoría de los caracteres chinos están compuestos por un radical semántico a la izquierda y un radical fonético a la derecha. El radical semántico puede proporcionar información semántica y el radical fonético puede proporcionar información relacionada con la pronunciación del carácter entero. Los pseudo-caracteres consistieron en diferentes partes sub-léxicas de los caracteres reales chinos y como consecuencia, también tenían radicales semánticos y fonéticos. Pero éstos no se podían leer y tampoco tenían un significado real. Para investigar los patrones de la activación cortical espaciotemporal subyacentes de los procesamientos ortográfico, fonológico y semántico de los caracteres chinos, utilizamos potencial relacionado con eventos (ERPs) para explorar el procesamiento de caracteres chinos y pseudo-caracteres mientras que 14 sanos estudiantes chinos veían los caracteres de forma pasiva. Los resultados demostraron que ambos, caracteres y pseudo-caracteres chinos evocaban potenciales negativos con picos alrededor de los 120 ms (N120), lo cual parece reflejar distinción inicial ortográfica y evaluación. Además, los pseudo-caracteres chinos provocaban una desviación ERP más positiva (P220) en comparación con los caracteres chinos entre 200-250 ms después de la aparición de los estímulos. Esto fue parecido a RP (potenciales de reconocimiento) y puede reflejar un proceso de integración del procesamiento fonológico y semántico basado en la información ortogr

    This is a case study of ongoing relations between the Phelps Dodge mining company, a United Steelworkers local representing 560 employees at the company's Chino Mines in New Mexico, and an array of other concerned stakeholders. This case study shows that labor can be a full partner in environmental advocacy, and even take a leadership role in building a strong multi-stakeholder alliance for corporate accountability. While the case also shows that corporate jobs blackmail is alive and well in the global economy, the labor community-coalition that has emerged at the mining complex has broken some new ground. The approach taken attends to diverse stakeholder interests--cultural protection issues of Native-American and Mexican-American ethnic groups; conservation, groundwater and Right-to-Know issues of traditional environmental constituencies; and environmental liability and disclosure concerns of corporate shareholders. Among the key developments are: A new approach to corporate reporting to shareholders as an enforcement and right-to-know tool; The use of the internet as an information dissemination and action tool; The potential for environmentally needed improvements to serve as a receptor for employment of workers at a mine during periods of reduced production.

  9. Tremor evidence for dynamically triggered creep events on the deep San Andreas Fault

    2010-12-01

    Deep tectonic tremor has been observed along major subduction zones and the San Andreas fault (SAF) in central and southern California. It appears to reflect deep fault slip, and it is often seen to be triggered by small stresses, including passing seismic waves from large regional and teleseismic earthquakes. Here we examine tremor activity along the Parkfield-Cholame section of the SAF from mid-2001 to early 2010, scrutinizing its relationship with regional and teleseismic earthquakes. Based on similarities in the shape and timing of seismic waveforms, we conclude that triggered and ambient tremor share common sources and a common physical mechanism. Utilizing this similarity in waveforms, we detect tremor triggered by numerous large events, including previously unreported triggering from the recent 2009 Mw7.3 Honduras, 2009 Mw8.1 Samoa, and 2010 Mw8.8 Chile earthquakes at teleseismic distances, and the relatively small 2007 Mw5.4 Alum Rock and 2008 Mw5.4 Chino Hills earthquakes at regional distances. We also find multiple examples of systematic migration in triggered tremor, similar to ambient tremor migration episodes observed at other times. Because these episodes propagate much more slowly than the triggering waves, the migration likely reflects a small, triggered creep event. As with ambient tremor bursts, triggered tremor at times persists for multiple days, probably indicating a somewhat larger creep event. This activity provides a clear example of delayed dynamic triggering, with a mechanism perhaps also relevant for triggering of regular earthquakes.

    More and more NMIs are realizing their primary scale themselves with fixed-point blackbodies as their reference standard. However, commercially available fixed-point blackbody furnaces of sufficient quality are not always easy to obtain. CHINO Corp. and NMIJ, AIST jointly developed a new compact fixed-point blackbody furnace. The new furnace has such features as 1) improved temperature uniformity when compared to previous products, enabling better plateau quality, 2) adoption of the hybrid fixed-point cell structure with internal insulation to improve robustness and thereby to extend lifetime, 3) easily ejectable and replaceable heater unit and fixed-point cell design, leading to reduced maintenance cost, 4) interchangeability among multiple fixed points from In to Cu points. The replaceable cell feature facilitates long term maintenance of the scale through management of a group of fixed-point cells of the same type. The compact furnace is easily transportable and therefore can also function as a traveling standard for disseminating the radiation temperature scale, and for maintaining the scale at the secondary level and industrial calibration laboratories. It is expected that the furnace will play a key role of the traveling standard in the anticipated APMP supplementary comparison of the radiation thermometry scale.

    Glutamine, the most abundant free amino acid in humans (Curi et al., 2007 [1]), has many functions. In addition to protein, amino acid, and nucleic acid biosynthesis, glutamine also regulates the expression of genes related to metabolism, cell defense, and signal transduction in humans (Curi et al., 2007 [1]; Brasse-Lagnel et al., 2009 [2]). Glutamine is also one of the major forms of nitrogen in rice (Fukumorita and Chino, 1982 [3]). In addition to metabolic and nutritional effects, glutamine may function as a signaling molecule to regulate gene expression in plants. To this end, we used microarray analysis to identify genes that are rapidly induced by 2.5 mM glutamine in rice roots. The results revealed that glutamine induced the expression of at least 35 genes involved in metabolism, transport, signal transduction, and stress responses within 30 min (Kan et al., 2015 [4]). Here, we provide the details of the experimental procedure associated with our microarray data deposited in NCBI's Gene Expression Omnibus (GEO ID: GSE56770). PMID:26697351

    Prevalence of the protozoan Perkinsus spp. in the gills of the pleasure oyster Crassostrea corteziensis from two estuaries in Nayarit, Mexico, was measured. The protozoan was identified by PCR amplification of the internal transcribed spacer (ITS) region of the rDNA of Perkinsus spp. The pathogen was found in 92% of oysters from Boca de Camichín and 77% of oysters from Pozo Chino. ITS sequences characterized from C. corteziensis showed 96-100% similarity to Perkinsus marinus. The most frequent ITS sequence (GenBank JQ266236) had 100% identity with the ITS locus of P. marinus from New Jersey, Maryland, South Carolina and Texas, and the second most frequent observed sequence (GenBank JQ266240) was 100% identical to ITS sequences of P. marinus from New Jersey, South Carolina, Louisiana, and Bahía Kino, Sonora, Mexico. The 14 sequences from the non-transcribed spacer (NTS) showed 98% similarity to P. marinus from Texas. The most frequent polymorphism identified was at nucleotide 446 of the ITS region; however, the NTS showed the highest nucleotide diversity, thereby suggesting that this region is suitable for genotype identification. Moreover, the most conserved ITS marker is better for species-specific diagnosis. Both the ITS and NTS sequences of P. marinus obtained from C. corteziensis were grouped in two clades, identifying two allelic variants of P. marinus.

    The complete genome sequence of a distinct variant of tomato yellow leaf curl virus-Israel (TYLCV-IL) and the DNA-A sequence of a new strain of tomato severe leaf curl virus (ToSLCV) isolated in San Luis Potosi, Mexico, are described and analyzed. The TYLCV-IL[MX:SLP:11] variant differs from all TYLCV-IL isolates described so far by a unique 42-nt duplicated sequence comprising a part of the conserved stem-loop element of the virion-strand replication origin and adjacent regulatory sequences. TYLCV-IL[MX:SLP:11] was associated with tomato chino La Paz virus (ToChLPV-B[MX:SLP:11]) in a Solanum pimpinellifolium plant, and with pepper huasteco yellow vein virus (PHYVV-[MX:SLP:11]) and ToSLCV-GT[MX:SLP:11] in a Solanum lycopersicum plant. In addition, a distinct ToSLCV exhibiting low sequence identity (<89 %) to other ToSLCV isolates from Mexico was found in a tomato plant collected in the same field. Sequence analysis of this new ToSLCV strain indicates that it is a recombinant of close relatives of ToSLCV-GT[MX:SLP:11] and ToChLPV-B[MX:SLP:11] found in mixed infections with TYLCV-IL[MX:SLP:11].

    The mantle is the major geochemical reservoir of most rock-forming elements in the Earth. Convection and plate-tectonic driven processes act to generate local and regional heterogeneity within the mantle, which in turn through thermal and chemical interactions modulates ongoing geophysical processes; this feedback shapes the dynamics of the deep interior. Consequently, these processes contribute to the evolution of the earth throughout its geological history. Up to now, the heterogeneity of the mantle has been extensively studied in terms of conventional methods using basalt chemistry, bulk rock and mineral major and trace element analysis of isolated xenolith specimens of varying lithology, and massif exposures. The milestone of the present study, part of an ongoing research project, is the application of in-situ analytical methods such as microprobe, LA-ICP-MS and high resolution SEM in order to provide high quality major and trace element analyses as well as elemental distribution of the coexisting phases in the preserved intra-mantle lithologies, Particularly, in the context of the current study we used selected compound xenoliths from San Carlos (Arizona, USA), Kilbourne Hole (New Mexico, USA), Cima Dome and Dish Hill suites (California, USA), San Quintin (Baja California, Mexico) and Chino Valley (Arizona, USA), from the Howard Wilshire collection archived at the Smithsonian Institution. The selection of these compound xenoliths was based upon freshness and integrity of specimens, maximum distance on both sides of lithologic contacts, and rock types thought most likely to represent subsolidus juxtaposition of different lithologies that later partially melted in contact. The San Carlos samples comprise composite xenoliths with websterite, lherzolite and clinopyroxenite layers or clinopyroxenite veins surrounded by lherzolite or orthopyroxenite-rich rims. The Kilbourne Hole suite comprises spinel-(olivine) clinopyroxenite and orthopyroxenite dikes cutting

    Due to the massive earthquakes and tsunami on March 11 2011 in Eastern Japan, Fukushima Daiichi nuclear power plant was severely damaged and some reactors were exploded. To know how the radioactive materials were spread and how much they were deposited into the land, it is important to enhance the accuracy of radioactive transport simulation model. However, there are uncertainties in the models including dry and wet deposition process in the models, meteorological field and release amount of radioactive materials. In this study we analyzed these uncertainties aiming for higher accuracy in the simulation. We modified the stable isotope mode of Regional Spectral Model (IsoRSM, Yoshimura et al., 2009) to enable to simulate the transport of the radioactive tracers, namely iodine 131 and cesium 137, by including the dry and wet deposition processes. With this model, we conducted a set of sensitivity experiments using different parameters in the deposition processes, different diffusivity in advection processes, and different domain sizes. The control experiment with 10km resolution covering most of Japan and surrounding oceans (132.7oE-151.5oE &28.3oN-46.7oN) and the emission estimated by Chino et al. (2011) showed reasonable temporal results for Toukatsu area (eastern part of Tokyo metropolis and western part of Chiba prefecture where low-level contamination was occurred), i.e., on 22 March, the tracers from Fukushima were reached and precipitated in a significant amount as wet deposition. Thus we conducted 4 experimental simulations to analyze the simulation uncertainty due to 1) different meteorological pattern, different parameters for 2) wet and 3) dry deposition and 4) diffusion. Though the temporal patterns of deposition of radioactive particles were somewhat similar each other in all experiments, we revealed that the impacts to the area mean deposition were large. Results of the simulations with different diffusivity and different domain size showed that the

    Three brachiopod faunas discussed herein record different depositional and tectonic settings along the southwestern margin of Laurentia (North America) during Devonian time. Depositional settings include inner continental shelf (Cerros de Los Murcielagos), medial continental shelf (Rancho Placeritos), and offshelf continental rise (Rancho Los Chinos). Ages of Devonian brachiopod faunas include middle Early (Pragian) at Rancho Placeritos in west-central Sonora, late Middle (Givetian) at Cerros de Los Murcielagos in northwestern Sonora, and late Late (Famennian) at Rancho Los Chinos in central Sonora. The brachiopods of these three faunas, as well as the gastropod Orecopia, are easily recognized in outcrop and thus are useful for local and regional correlations. Pragian brachiopods dominated by Acrospirifer and Meristella in the "San Miguel Formation" at Rancho Placeritos represent the widespread Appohimchi Subprovince of eastern and southern Laurentia. Conodonts of the early to middle Pragian sulcatus to kindlei Zones associated with the brachiopods confirm the ages indicated by the brachiopod fauna and provide additional information on the depositional setting of the Devonian strata. Biostratigraphic distribution of the Appohimchi brachiopod fauna indicates continuous Early Devonian shelf deposition along the entire southern margin of Laurentia. The largely emergent southwest-trending Transcontinental arch apparently formed a barrier preventing migration and mixing of many genera and species of brachiopods from the southern shelf of Laurentia in northern Mexico to the western shelf (Cordilleran mio-geocline) in the western United States. Middle Devonian Stringocephalus brachiopods and Late Devonian Orecopia gastropods in the "Los Murcielagos Formation" in northwest Sonora represent the southwest-ernmost occurrence of these genera in North America and date the host rocks as Givetian and Frasnian, respectively.

    Two field populations of Culicoides variipennis (Coquillett) from southern California, C. v. occidentalis Wirth & Jones from the Salton Sea and C. v. sonorensis Wirth & Jones from a dairy wastewater pond in the Chino Basin, were sampled monthly from February to July (6-7 mo). Morphometric analyses of slide-mounted adults reared from field-collected larvae and pupae indicated that females of the 2 forms were indistinguishable. Two of the standard characters, wing length and mandibular teeth, were correlated with seasonal temperature changes. Males of C. v. sonorensis were distinguishable by the presence of spicules on the aedeagus, which were entirely lacking in C. v. occidentalis. Two populations of C. v. occidentalis (Salton Sea and Bolsa Chica Marsh) and a laboratory strain of C. v. sonorensis hybridized successfully in the laboratory and were maintained for 6 generations. Differential hybrid viability (F1) was observed in reciprocal crosses. Males of C. v. occidentalis mated with females of C. v. sonorensis resulted in a lower egg hatch (7.4%) than did the reciprocal cross (75.6%). Hybrid males displayed spicules on the aedeagus (a character of C. v. sonorensis), but the number of spicules was sometimes reduced compared with parental C. v. sonorensis (AA strain). Spicules in a field population of C. v. sonorensis were similar in number to the laboratory C. v. sonorensis-C. v. occidentalis hybrids. Based on successful hybridization, the 2 forms should be considered closely related. The 2 forms are separated ecologically by the nature and distribution of their larval habitats. PMID:9151490

    Culture of the pleasure oyster Crassostrea corteziensis is emerging as an alternative to the Pacific oyster (Crassostrea gigas) for oyster producers, who face severe mortalities since 1997 in Northwest México. For determining the health status of this species, we conducted a histopathological analysis of cultured populations from two estuaries in the Pacific coast of México. Macroscopical analysis revealed animals with transparent and retracted mantle. Histopathological analysis of these specimens showed tissue alterations and parasitic forms consistent with Perkinsus sp. infection. Stages of the parasite identified included tomont and trophozoites with an eccentric vacuole characteristic of Perkinsus spp. Pieces of tissues of infected oysters were incubated in Fluid Thioglycollate Medium (FTM) resulting in blue-black hypnospores after incubation. The identity of the parasite was confirmed by species specific PCR-based assay in DNA samples from oysters, tissue fractions from FTM cultures, and deparaffined samples with Perkinsus-like parasite detected by histology. Sequencing of positive amplified fragments (307bp) showed a sequence similar to Perkinsus marinus strain TXsc NTS ribosomal RNA gene (100% coverage and 98% identity, GenBank Accession No. AF497479.1) and to P. marinus, Genomic DNA, (100% coverage and 97% identity, GenBank Accession No. S78416.1). The prevalence of P. marinus varied from 1 to 5% in Boca del Camichín and from 1 to 6% in Pozo Chino. In general, the intensity of infection was moderate. The infection was observed in oysters from 31 to 110mm of shell length. This is the first record of P. marinus in oysters from the North America Pacific coast and the first record in C. corteziensis. The origin of this parasite in the area is unknown, but it may be associated to introductions of Crassostrea virginica from the East coast of United States of America or Gulf of México.

    Methane (CH4), carbon dioxide (CO2), carbon monoxide (CO), and C2-C5 alkanes were measured throughout the Los Angeles (L.A.) basin in May and June 2010. We use these data to show that the emission ratios of CH4/CO and CH4/CO2 in the L.A. basin are larger than expected from population-apportioned bottom-up state inventories, consistent with previously published work. We use experimentally determined CH4/CO and CH4/CO2 emission ratios in combination with annual State of California CO and CO2 inventories to derive a yearly emission rate of CH4 to the L.A. basin. We further use the airborne measurements to directly derive CH4 emission rates from dairy operations in Chino, and from the two largest landfills in the L.A. basin, and show these sources are accurately represented in the California Air Resources Board greenhouse gas inventory for CH4. We then use measurements of C2-C5 alkanes to quantify the relative contribution of other CH4 sources in the L.A. basin, with results differing from those of previous studies. The atmospheric data are consistent with the majority of CH4 emissions in the region coming from fugitive losses from natural gas in pipelines and urban distribution systems and/or geologic seeps, as well as landfills and dairies. The local oil and gas industry also provides a significant source of CH4 in the area. The addition of CH4 emissions from natural gas pipelines and urban distribution systems and/or geologic seeps and from the local oil and gas industry is sufficient to account for the differences between the top-down and bottom-up CH4 inventories identified in previously published work.

    Recent advances in distributed computing provide exciting opportunities for seismic data collection. We are in the early stages of implementing a high density, low cost strong-motion network for rapid response and early warning by placing accelerometers in schools, homes, offices, government buildings, fire houses and more. The Quake Catcher Network (QCN) employs existing networked laptops and desktops to form a dense, distributed computing seismic network. Costs for this network are minimal because the QCN uses 1) strong motion sensors (accelerometers) already internal to many laptops and 2) low-cost universal serial bus (USB) accelerometers for use with desktops. The Berkeley Open Infrastructure for Network Computing (BOINC!) provides a free, proven paradigm for involving the public in large-scale computational research projects. The QCN leverages public participation to fully implement the seismic network. As such engaging the public to participate in seismic data collection is not only an integral part of the project, but an added value to the QCN. The software provides the client-user with a screen-saver displaying seismic data recorded on their laptop or recently detected earthquakes. Furthermore, this project installs sensors in K-12 classrooms as an educational tool for teaching science. Through a variety of interactive experiments students can learn about earthquakes and the hazards earthquakes pose. In the first six months of limited release of the QCN software, we successfully received triggers and waveforms from laptops near the M 4.7 April 25, 2008 earthquake in Reno, Nevada and the M 5.4 July 29, 2008 earthquake in Chino, California (as well as a few 3.6 and higher events). This fall we continued to expand the network further by installing seismometers in K-12 schools, museums, and government buildings in the greater Los Angeles basin and the San Francisco Bay Area. By summer 2009 we expect to have 1000 USB sensors deployed in California, in addition

    We demonstrate the use of compact solar-tracking Fourier transform spectrometers (Bruker EM27/SUN) for differential measurements of the column-averaged dry-air mole fractions of CH4 and CO2 within urban areas. Using Allan variance analysis, we show that the differential column measurement has a precision of 0.01 % for XCO2 and XCH4 with an optimum integration time of 10 min, corresponding to Allan deviations of 0.04 ppm and 0.2 ppb, respectively. The sensor system is very stable over time and after relocation across the continent. We report tests of the differential column measurement, and its sensitivity to emission sources, by measuring the downwind-minus-upwind column difference ΔXCH4 across dairy farms in the Chino area, California, and using the data to verify emissions reported in the literature. Ratios of spatial column differences ΔXCH4/ΔXCO2 were observed across Pasadena within the Los Angeles basin, indicating values consistent with regional emission ratios from the literature. Our precise, rapid measurements allow us to determine significant short-term variations (5-10 min) of XCO2 and XCH4 and to show that they represent atmospheric phenomena.Overall, this study helps establish a range of new applications for compact solar-viewing Fourier transform spectrometers. By accurately measuring the small differences in integrated column amounts across local and regional sources, we directly observe the mass loading of the atmosphere due to the influence of emissions in the intervening locale. The inference of the source strength is much more direct than inversion modeling using only surface concentrations and less subject to errors associated with small-scale transport phenomena.

    We use global positioning system (GPS) geodesy and synthetic aperture radar (SAR) interferometry to distinguish between interseismic strain accumulation and anthropogenic motion in metropolitan Los Angeles. We establish a relationship between horizontal and vertical seasonal oscillations of the Santa Ana aquifer, use this relationship to infer cumulative horizontal anthropogenic motions from cumulative vertical motions caused by water and oil resource management, and estimate horizontal interseismic velocities corrected for anthropogenic effects. Vertical anthropogenic rates from 1992 to 1999 are slower than 3 mm yr-1 in the Santa Ana and San Gabriel aquifers and faster than 5 mm yr-1 in the Chino aquifer and in many oil fields. Inferred horizontal anthropogenic velocities are faster than 1 mm yr-1 at 18 of 46 GPS sites. Northern metropolitan Los Angeles is contracting, with the 25 km south of the San Gabriel Mountains shortening at 4.5 ± 1 mm yr-1 (95% confidence limits). The thrust fault in an elastic edge dislocation model of the observed strain is creeping at 9 ± 2 mm yr-1 beneath and north of a position 6 ± 2 km deep and 8 ± 8 km north of downtown Los Angeles. The model fault is near the Los Angeles segment of the Puente Hills thrust but south of the Sante Fe Springs segment of the thrust. Disagreement between the 6 km locking depth in the model and the 15 km seismogenic depth inferred from earthquakes suggests that the elastic continuum model may be unsatisfactory; models with different stiffnesses of sedimentary basin and crystalline basement must be investigated.

    A novel begomovirus isolated from a Sida rhombifolia plant collected in Sinaloa, Mexico, was characterized. The genomic components of sida mosaic Sinaloa virus (SiMSinV) shared highest sequence identity with DNA-A and DNA-B components of chino del tomate virus (CdTV), suggesting a vertical evolutionary relationship between these viruses. However, recombination analysis indicated that a short segment of SiMSinV DNA-A encompassing the plus-strand replication origin and the 5´-proximal 43 codons of the Rep gene was derived from tomato mottle Taino virus (ToMoTV). Accordingly, the putative cis- and trans-acting replication specificity determinants of SiMSinV were identical to those of ToMoTV but differed from those of CdTV. Modeling of the SiMSinV and CdTV Rep proteins revealed significant differences in the region comprising the small β1/β5 sheet element, where five putative DNA-binding specificity determinants (SPDs) of Rep (i.e., amino acid residues 5, 8, 10, 69 and 71) were previously identified. Computer-assisted searches of public databases led to identification of 33 begomoviruses from three continents encoding proteins with SPDs identical to those of the Rep encoded by SiMSinV. Sequence analysis of the replication origins demonstrated that all 33 begomoviruses harbor potential Rep-binding sites identical to those of SiMSinV. These data support the hypothesis that the Rep β1/β5 sheet region determines specificity of this protein for DNA replication origin sequences.

    The Arizona Geological Survey uses online broadcasting (Webcast or 'Web TV') to help fulfill our statutory mission to 'Inform, advise and assist the public in matters concerning the geological processes, materials and landscapes and the development and use of the mineral resources of this state.' We launched a monthly online broadcast called 'Arizona Mining Review' via Livestream, a low-cost or free video streaming service. The show provides news, interviews, and discussions about mining and mineral resources topics of interest in Arizona, the nation's second largest non-fuel mining state. The costs to set up and broadcast are minor. Interviews with local guests are held in a corner of the AZGS conference room with easy chairs and a couch; long-distance interviews are held via Skype. The broadcast originates from a desktop computer with a webcam, a $60 microphone, three sets of earbud headphones and a powered amplifier. During broadcasts, we supplement interview footage with slides, photos, or video clips that we have or are provided by guests. Initial broadcasts were live; recordings of these were later uploaded to our YouTube channel. Because scheduling and executing a live Internet broadcast is stressful and demanding for both the production team and guests, we recently elected to record and produce episodes prior to broadcasting them. This allows us more control over supplementary materials used during the broadcast; it also permits us to record the broadcast using a high-definition digital video camera that cannot be used for streaming video. In addition to the Arizona Mining Review, we record conferences and workshops and special presentations on topical issues. A video on the recently discovered Little Chino fault has drawn over 3,000 views. Our latest presentations are short 1-2 minute 'video abstracts' delivered by authors of new publications released by the Survey. These include maps and graphics from the reports to help illustrate the topics and their

    Recent field study reviews on the greenhouse gas methane (CH4) found significant underestimation from fossil fuel industry and husbandry. The 2014 COMEX campaign seeks to develop methods to derive CH4 and carbon dioxide (CO2) from remote sensing data by combining hyperspectral imaging (HSI) and non-imaging spectroscopy (NIS) with in situ airborne and surface data. COMEX leverages synergies between high spatial resolution HSI column abundance maps and moderate spectral/spatial resolution NIS. Airborne husbandry data were collected for the Chino dairy complex (East Los Angeles Basin) by NIS-MAMAP, HSI-Mako thermal-infrared (TIR); AVIRIS NG shortwave IR (SWIR), with in situ surface mobile-AMOG Surveyor (AutoMObile greenhouse Gas)-and airborne in situ from a Twin Otter and the AlphaJet. AMOG Surveyor uses in situ Integrated Cavity Off Axis Spectroscopy (OA-ICOS) to measure CH4, CO2, H2O, H2S and NH3 at 5-10 Hz, 2D winds, and thermal anomaly in an adapted commuter car. OA-ICOS provides high precision and accuracy with excellent stability. NH3 and CH4 emissions were correlated at dairy size-scales but not sub-dairy scales in surface and Mako data, showing fine-scale structure and large variations between the numerous dairies in the complex (herd ~200,000-250,000) embedded in an urban setting. Emissions hotspots were consistent between surface and airborne surveys. In June, surface and MAMAP data showed a weak overall plume, while surface and Mako data showed a stronger plume in late (hotter) July. Multiple surface plume transects using NH3 fingerprinting showed East and then NE advection out of the LA Basin consistent with airborne data. Long-term trends were investigated in satellite data. This study shows the value of synergistically combined NH3 and CH4 remote sensing data to the task of CH4 source attribution using airborne and space-based remote sensing (IASI for NH3) and top of atmosphere sensitivity calculations for Sentinel V and Carbon Sat (CH4).

    The SCEC Community Velocity Model Toolkit (CVM-T) enables earthquake modelers to quickly build, visualize, and validate large-scale 3D velocity meshes using SCEC CVM-H or CVM-4. CVM-T is comprised of three main components: (1) a current SCEC community velocity model for Southern California, (2) tools for extracting meshes from this model and visualizing them, and (3) an automated test framework for evaluating new releases of CVMs using SCEC’s AWP-ODC forward wave propagation software and one, or more, ground motion goodness of fit (GoF) algorithms. CVM-T is designed to help SCEC modelers build large-scale velocity meshes by extracting material properties from the most current version of Community Velocity Model H (CVM-H) and to provide a consistent interface as new CVM-H versions are developed. The CVM-T software provides a highly-scalable interface to CVM-H 6.2 (and later) voxets. Along with an improved interface to CVM-H material properties, the CVM-T software adds a geotechnical layer (GTL) to CVM-H 6.2+ based on Ely’s Vs30-derived GTL. The initial release of CVM-T also extends the coverage region for CVM-H 6.2 with a Hadley-Kanamori 1D background. Smoothing is performed within the transition boundary between the core model and the 1D background. The user interface now includes a C API that allows applications to query the model either by elevation or depth. The Extraction and Visualization Tools (EVT) include a parallelized 3D mesh generator which can quickly generate meshes (consisting of Vp, Vs, and density) from either CVM-H or CVM-4 with over 100 billion points. Python plotting scripts can be employed to plot horizontal or profile slices from existing meshes or directly from either CVM. The Automated Test Framework (ATF) is a system for quantitatively evaluating new versions of CVM-H and ensuring that the model improves against prior versions. The ATF employs the CruiseControl build and test framework to run an AWP-ODC simulation for the 2008 Chino

    This is the second in a series of interpretive reports on subsurface outflow from the ground-water basins of San Bernardino County, Calif., prepared by the U.S. Geological Survey in cooperation with the San Bernardino County Flood Control District. One principal purpose of the study was to estimate the ground-water outflow from the Bunker Hill basin to the Rialto-Colton basin across the San Jacinto fault, which, except locally, forms a nearly impermeable boundary between the two basins. In addition, the report deals qualitatively with the geology, the fault barriers that divide the area into several ground-water basins, the physical nature and degree of imperviousness of the barriers, the occurrence and movement of ground water and fluctuations of water level in the basins, and the chemical quality of surface and ground waters in the San Bernardino area. The report includes a geologic map and sections, water-level-contour maps and profiles, and hydrographs of selected well. The Santa Ana River, the principal stream, flows generally westward across the area. Channels of the river and its tributaries overlie a large irregular structural depression filled with alluvial deposits ranging in age from late Tertiary to Recent and forming a valley bounded on the north by the San Gabriel Mountains, on the east by the San Bernardino Mountains, and on the south by an irregular group of hills. Large alluvial fans underlie most of the area, but its landforms also include alluvial benches and terraces near the mountains, stream channels, and elongate hills, ridges, and scarps along the trace of the San Jacinto fault, which strikes northwestward across the valley about in the center of the area. This fault and others divide the area into ground-water basins, which include the Bunker Hill, Rialto-Colton, upper and lower Lytle and Chino basins. The water-bearing deposits include the following units: the younger alluvium. of Recent age, which occupies principally the backfilled

    ) environments, so we have included checks during the installation process to alert users about potential conflicts. We also describe how UCVM can create an octree-based database representation of a velocity model which can be directly queried by 3D wave propagation simulation codes using the open source etree library. We will discuss how this approach was used to create an etree for a 4-Hz Chino Hills simulation. Finally, we show how the UCVM software can integrate NetCDF utility code to produce 3D velocity model files compatible with open source NetCDF data viewers. This demonstrates that UCVM can generate meshes from any compatible community velocity model and that the resulting models can be visualized without the need for complex secondary tools. This illustrates how developers can easily write tools that can convert data from one format to another using the UCVM API.

    This is the final technical report for the RP-5 Renewable Energy Efficiency Project (REEP). The report summarizes, in a comprehensive manner, all the work performed during the award period extending between July 12, 2002 and June 30, 2007. This report has been prepared in accordance with the Department of Energy (DOE) Guidelines and summarizes all of the activities that occurred during the award period. The RP-5 Renewable Energy Efficiency Project, under development by the Inland Empire Utilities Agency (IEUA), is comprised of a series of full-scale demonstration projects that will showcase innovative combinations of primary and secondary generation systems using methane gas derived from local processing of biosolids, dairy manure and other organic material. The goal of the project is to create renewable energy-based generation systems with energy efficiencies 65% or more. The project was constructed at the 15 MGD Regional Wastewater Treatment Plant No. 5 located in the City of Chino in California where the Agency has constructed its new energy-efficient (platinum-LEED rating) headquarters building. Technologies that were featured in the project include internal combustion engines (ICE), absorption chillers, treatment plant secondary effluent cooling systems, heat recovery systems, thermal energy storage (TES), Organic Rankine Cycle (ORC) secondary power generation system, the integration of a future fuel cell system, gas cleaning requirements, and other state-of-the-art design combinations. The RP-5 REEP biogas source is coming from three manure digesters which are located within the RP-5 Complex and are joined with the RP-5 REEP through gas conveyance pipelines. Food waste is being injected into the manure digesters for digester gas production enhancement. The RP-5 REEP clearly demonstrates the biogas production and power generation viability, specifically when dealing with renewable and variable heating value (Btu) fuel. The RP-5 REEP was challenged with meeting

    capita water use for exempt wells. Accuracy of the simulated groundwater-flow system was evaluated by using observational control from water levels in wells, estimates of base flow from streamflow records, and estimates of spring discharge. Major results from the simulations include the importance of variations in recharge rates throughout the study area and recharge along ephemeral and losing stream reaches in alluvial basins. Insights about the groundwater-flow systems in individual basins include the hydrologic influence of geologic structures in some areas and that stream-aquifer interactions along the lower part of the Little Colorado River are an effective control on water level distributions throughout the Little Colorado River Plateau basin. Better information on several aspects of the groundwater flow system are needed to reduce uncertainty of the simulated system. Many areas lack documentation of the response of the groundwater system to changes in withdrawals and recharge. Data needed to define groundwater flow between vertically adjacent water-bearing units is lacking in many areas. Distributions of recharge along losing stream reaches are poorly defined. Extents of aquifers and alluvial lithologies are poorly defined in parts of the Big Chino and Verde Valley sub-basins. Aquifer storage properties are poorly defined throughout most of the study area. Little data exist to define the hydrologic importance of geologic structures such as faults and fractures. Discharge of regional groundwater flow to the Verde River is difficult to identify in the Verde Valley sub-basin because of unknown contributions from deep percolation of excess surface water irrigation.

    Urban areas are home to 54% of the total global population and account for ˜ 70% of total fossil fuel emissions. Accurate methods for measuring urban and regional scale carbon fluxes are required in order to design and implement policies for emissions reduction initiatives. In this paper, we demonstrate novel applications of compact solar-tracking Fourier transform spectrometers (Bruker EM27/SUN) for differential measurements of the column-averaged dry-air mole fractions (DMFs) of CH4 and CO2 within urban areas. Our differential column method uses at least two spectrometers to make simultaneous measurements of CO2, CH4 and O2 column number densities. We then compute the column-averaged DMFs XG for a gas G and the differences ΔXG between downwind and upwind stations. By accurately measuring the small differences in integrated column amounts across local and regional sources, we directly observe the mass loading of the atmosphere due to the influence of emissions in the intervening locale. The inference of the source strength is much more direct than inversion modeling using only surface concentrations, and less subject to errors associated with modeling small-scale transport phenomena. We characterize the differential sensor system using Allan variance analysis and show that the differential column measurement has a precision of 0.01% for XCO2 and XCH4 using an optimum integration time of 10 min, which corresponds to standard deviations of 0.04 ppm, and 0.2 ppb, respectively. The sensor system is very stable over time and after relocation across the contiguous US, i.e. the scaling factors between the two Harvard EM27/SUNs and the measured instrument line function parameters are consistent. We use the differential column measurements to determine the emission of an area source. We measure the downwind minus upwind column gradient ΔXCH4 (˜ 2 ppb, 0.1%) across dairy farms in the Chino California area, and input the data to a simple column model for comparison with

    deeper and shows a more complex 3D distribution in areas exhibiting compressional tectonics within the Pacific plate. The VP values are 0.2 to 0.4 km/s too high to support an abundant occurrence of schist beneath the Mojave Desert and the San Gabriel Mountains. The models reflect mapped changes, from east to west, in the lithology of the Peninsular Ranges. The interface between the shallow Moho of the Continental Borderland and the deep Moho of the continent forms a broad zone to the north beneath the western Transverse Ranges, Ventura basin and the Los Angles Basin and a narrow zone to the south, along the Peninsular Ranges. Similarly, the 3D Qp model includes several features that correspond to regional tectonic features and possibly the thermal structure of the southern California crust. A clear low Qp zone extends from the San Bernardino Basin, across the Chino Basin, San Gabriel Valley, into the Los Angeles Basin. This zone is consistent with the geology and decreases with depth from east to west. The Peninsular Ranges have a high Qp zone consistent with the high velocities in the 3D VP model. There are also zones of high Qp in the southern Mojave and southern Sierras. Several clear transition zones of rapidly varying Qp, extend across major late Quaternary faults and connect regions of high and low Qp. The strongest low Qp zone coincides with the Salton Trough where near-surface low Qp is associated with the sediments and the deeper low Qp may be associated with elevated mid-crustal temperatures.

El presente experimento encontró un efecto de la modalidad diferente de los resultados de los estudios anteriores. En concreto, el reconocimiento falso ha resultado ser mayor después del estudio visual que después del estudio auditivo, especialmente en caso de la presentación en bloques en comparación con la condición de presentación aleatoria. Los autores argumentan que este efecto inverso de la modalidad puede ser causado por diferentes características de codificación y procesamiento entre caracteres chinos y palabras inglesas. En comparación con las palabras inglesas, los grafemas visuales de las palabras críticas en chino tienen probabilidad de ser activadas y codificadas en las mentes de los participantes, por tanto, es más difícil discriminar posteriores grafemas internos de los que fueron presentados en la modalidad visual. Por tanto, la presentación visual podría conducir a más falsos reconocimientos que la presentación auditiva en los listados de palabras chinas. Los resultados del presente experimento demostraron que la activación semántica durante las fases de codificación y recuperación jugó un rol importante en el efecto de falso reconocimiento según modalidad y que nuestros resultados se pueden explicar teniendo en cuenta la activación y la vigilancia.

  1. Analog model study of the ground-water basin of the Upper Coachella Valley, California

    1974-01-01

    An analog model of the ground-water basin of the upper Coachella Valley was constructed to determine the effects of imported water on ground-water levels. The model was considered verified when the ground-water levels generated by the model approximated the historical change in water levels of the ground-water basin caused by man's activities for the period 1986-67. The ground-water basin was almost unaffected by man's activities until about 1945 when ground-water development caused the water levels to begin to decline. The Palm Springs area has had the largest water-level decline, 75 feet since 1986, because of large pumpage, reduced natural inflow from the San Gorgonio Pass area, and diversions of natural inflows at Snow and Falls Creeks and Chino Canyon starting in 1945. The San Gorgonio Pass inflow had been reduced from about 18,000 acre-feet in 1986 to about 9,000 acre-feet by 1967 because of increased ground-water pumpage in the San Gorgonio Pass area, dewatering of the San Gorgonio Pass area that took place when the tunnel for the Metropolitan Water District of Southern California was drilled, and diversions of surface inflow at Snow and Falls Creeks. In addition, 1944-64 was a period of below-normal precipitation which, in part, contributed to the declines in water levels in the Coachella Valley. The Desert Hot Springs, Garnet Hill, and Mission Creek subbasins have had relatively little development; consequently, the water-level declines have been small, ranging from 5 to 15 feet since 1986. In the Point Happy area a decline of about 2 feet per year continued until 1949 when delivery of Colorado River water to the lower valley through the Coachella Canal was initiated. Since 1949 the water levels in the Point Happy area have been rising and by 1967 were above their 1986 levels. The Whitewater River subbasin includes the largest aquifer in the basin, having sustained ground-water pumpage of about 740,000 acre-feet from 1986 to 1967, and will probably

En este estudio se examinó el estigma hacia el VIH/SIDA entre proveedores de servicios chinos mediante la comparación de sus actitudes hacia las personas que viven con el VIH/SIDA con su precepción de las normas sociales relacionadas a personas que viven con el VIH/SIDA. Se seleccionaron al azar tres hospitales provinciales, cuatro de la ciudadlhospitales de la prefectura, diez hospitales del condado, 18 clinicas de salud municipales, y 54 clinicas de la aldea de Yunnan, China. Los médicos y las enfermeras fueron incluidos en la muestra de manera aleatoria y considerando la relación enfermera-médico de cada hospital o clínica. Una muestra grande de técnicos de laboratorio fue incluida en el estudio con el fin de garantizar su adecuada representación en los análisis. Un total de 1,101 proveedores de servicios participaron de manera voluntaria en una encuesta anónima, en la cual se evaluaron las caracteristicas demográficas, las actitudes individuales, asi como la percepción de las normas sociales hacia personas que viven con el VIH/SIDA, la intención de discriminación laboral, las actitudes globales de prejuicio y los conocimientos sobre el VIH/SIDA. La mayor parte de la muestra presentó similitudes entre sus opiniones personales y lo que ellos pensaban, eran las creencias de la mayoria de las personas de su sociedad. En una regresión logistica multiple se pudo observar que los participantes más jóvenes o que indicaron un contacto personal con personas que viven con el VIH/SIDA, mostraron de manera más significativa respecto de esta población actitudes personales mucho más liberales que las normas sociales percibidas.
