    This cloud free color infrared view of San Francisco and Bay Area, CA (38.0N, 122.5W) is unusual because the city is normally concealed from view by clouds and fog. Gray tones represent urban areas and the red toned areas are vegetated. Within the city, parks easily stand out from the well-developed parts of the city as enclaves of color. The trace of the San Andreas fault shows as a straight valley running across the San Francisco peninsula.

    The San Francisco Bay watershed covers 40% of the State of California. Nonpoint source pollutants from cars, lawns, houses, parks and people residing within the watershed contribute contamination into San Francisco Bay. To measure the contribution from our neighborhoods we collected runoff from storm-drains at 10 different sites around San Francisco and tested them for heavy metals, Total Organic Carbons (TOC), and Methylene Blue Active Substances (MBAS) during a six-month period. Each sample site location is situated within one block of each participant's home. The goal of this study was to determine the contaminants contributed as nonpoint source pollution into San Francisco Bay. Our results show that a variety of contaminants are entering the Bay's ecosystem via sources in our residential settings. While this contribution may be thought of as unsubstantial, our results show that our neighborhoods are significant sources of watershed pollution.

  8. Swash zone characteristics at Ocean Beach, San Francisco, CA

    USGS Publications Warehouse

    Erikson, L.H.; Hanes, D.M.; Barnard, P.L.; Gibbs, A.E.

    2007-01-01

    Runup data collected during the summer of 2005 at Ocean Beach, San Francisco, CA are analyzed and considered to be typical summer swash characteristics at this site. Analysis shows that the beach was dissipative with Iribarren numbers between 0.05 and 0.4 and that infragravity energy dominated. Foreshore slopes were mild between 0.01 and 0.05 with swash periods on the order of a minute. Predicted runup heights obtained with six previously developed analytical runup formulae were compared to measured extreme runup statistics. Formulations dependent on offshore wave height, foreshore slope and deep water wavelength gave reasonable results.

  12. Using topography to decipher the uplift history of the western San Gabriel Mountains, CA

    NASA Astrophysics Data System (ADS)

    Dibiase, R. A.; Whipple, K. X.; Heimsath, A. M.

    2010-12-01

    Transient landscapes serve an important role in tectonic geomorphology, both by echoing the temporal changes of driving climatic or tectonic forces, and by providing field settings to discriminate among different surface process models that behave similarly under steady-state conditions. Here we investigate the surface expression of a two-staged transient signal in the 300 km2 Big Tujunga river basin in the western San Gabriel Mountains using a combination of DEM analysis, detailed field surveys of stream channels, and a rich erosion rate dataset. The upper (earlier) transient in the Big Tujunga catchment has nearly propagated through the entire fluvial network, with only isolated patches of an elevated low-relief weathering surface remaining. The lower transient, however, is characterized by a dramatic inner gorge with over-steepened valley walls and fluvial hanging valleys. In both cases, an increase in the rate of local base-level fall resulted in the propagation of a wave of incision upstream through the landscape, with discrete knickpoints separating adjusting from relict portions of the landscape. We use a 10 m digital elevation model to extract channel long profiles and hillslope angles in order to determine knickpoint elevations. Concordance in knickpoint elevations allows the estimation of the timing of the onset of the transient using a relationship between channel steepness and erosion rate (derived from detrital cosmogenic 10Be concentrations) developed for the region. We find the age of the upper transient to be ca. 6 Ma, which corresponds to the initiation of uplift in the San Gabriel Mountains associated with the transfer of slip from the San Gabriel Fault to the current trace of the San Andreas Fault. The younger transient dates to ca. 2 Ma, which overlaps with estimates of activation of the San Jacinto Fault Zone, whose inception has been linked to increases in rock uplift rate in both the eastern San Gabriel Mountains and in the nearby San

    The bioavailability and toxicity of copper (Cu) in Shelter Island Yacht Basin (SIYB), San Diego, CA, USA, was assessed with simultaneous toxicological, chemical, and modeling approaches. Toxicological measurements included laboratory toxicity testing with Mytilus galloprovincialis (Mediterranean mussel) embryos added to both site water (ambient) and site water spiked with multiple Cu concentrations. Chemical assessment of ambient samples included total and dissolved Cu concentrations, and Cu complexation capacity measurements. Modeling was based on chemical speciation and predictions of bioavailability and toxicity using a marine Biotic Ligand Model (BLM). Cumulatively, these methods assessed the natural buffering capacity of Cu in SIYB during singular wet and dry season sampling events. Overall, the three approaches suggested negligible bioavailability, and isolated observed or predicted toxicity, despite an observed gradient of increasing Cu concentration, both horizontally and vertically within the water body, exceeding current water quality criteria for saltwater.

    Shadows cast by trees and buildings can limit the solar access of rooftop solar-energy systems, including photovoltaic panels and thermal collectors. This study characterizes rooftop shading in a residential neighborhood of San Jose, CA, one of four regions analyzed in a wider study of the solar access of California homes.High-resolution orthophotos and LiDAR (Light Detection And Ranging) measurements of surface height were used to create a digital elevation model of all trees and buildings in a 4 km2 residential neighborhood. Hourly shading of roofing planes (the flat elements of roofs) was computed geometrically from the digital elevation model. Parcel boundaries were used to determine the extent to which roofing planes were shaded by trees and buildings in neighboring parcels.In the year in which surface heights were measured (2005), shadows from all sources ("total shading") reduced the insolation received by S-, SW-, and W-facing residential roofing planes in the study area by 13 - 16percent. Shadows cast by trees and buildings in neighboring parcels reduced insolation by no more than 2percent. After 30 years of simulated maximal tree growth, annual total shading increased to 19 - 22percent, and annual extraparcel shading increased to 3 - 4percent.

  7. Noncharacteristic Slip on the Northern San Andreas Fault at the Vedanta Marsh, Marin County, CA

    NASA Astrophysics Data System (ADS)

    Zhang, H.; Niemi, T. M.; Allison, A.; Fumal, T. E.

    2004-12-01

    Three-dimensional excavations along the 1906 trace of the northern San Andreas fault at the Vedanta marsh paleoseismic site near Olema, CA have yielded new data on the timing and amount of slip during the penultimate earthquake on this fault section. The excavations exposed a 3-m-wide paleochannel that has been offset right-laterally 7.8-8.3 m by coseismic slip during the past two large earthquakes: 1906 and the penultimate earthquake. The paleochannel was eroded into a silty clay marsh deposit and was filled after AD 1400. Both the silty clay layer and the paleochannel deposit are directly overlain by an in situ burn/peat sequence. The penultimate earthquake occurred while the peat was at the ground surface whereas faulting from the 1906 earthquake terminates within an overlying gravel/fill sequence. Preliminary OxCal analyses of radiocarbon dates indicate that the penultimate earthquake occurred in the late 17th to early 18th century. In plan view, two main fault traces were mapped in the excavation. The northwestern portion of the paleochannel is offset across a single fault trace. Just southeast of this portion of the channel the fault splits into two traces. We believe that one of these traces likely slipped only during 1906 and the other trace slipped on during the penultimate earthquake. Unfortunately, the overlying stratigraphic section that could resolve the exact reconstruction of movement on these faults is missing due to the excavation of an artificial drainage ditch at this location in the 1940's. Matching the north margin of the paleochannel to the first exposure of gravel in the zone between the two fault traces gives an offset of 5 m. We have historic records that show the 1906 coseismic slip near the study site was about 5m from field notes of David Starr Jordan (Stanford University Archives) who describes two 16 ft (5m) offsets: one of a tree located about 150m SE of the offset channel and the other of a path to the Shafter barn located about 300m

  8. How Fault Geometry Affects Dynamic Rupture Models of Earthquakes in San Gorgonio Pass, CA

    NASA Astrophysics Data System (ADS)

    Tarnowski, J. M.; Oglesby, D. D.; Cooke, M. L.; Kyriakopoulos, C.

    2015-12-01

    We use 3D dynamic finite element models to investigate potential rupture paths of earthquakes propagating along faults in the western San Gorgonio Pass (SGP) region of California. The SGP is a structurally complex area along the southern California portion of the San Andreas fault system (SAF). It has long been suspected that this structural knot, which consists of the intersection of various non-planar strike-slip and thrust fault segments, may inhibit earthquake rupture propagation between the San Bernardino and Banning strands of the SAF. The above condition may limit the size of potential earthquakes in the region. Our focus is on the San Bernardino strand of the SAF and the San Gorgonio Pass Fault zone, where the fault connectivity is not well constrained. We use the finite element code FaultMod (Barall, 2009) to investigate how fault connectivity, nucleation location, and initial stresses influence rupture propagation and ground motion, including the likelihood of through-going rupture in this region. Preliminary models indicate that earthquakes that nucleate on the San Bernardino strand and propagate southward do not easily transfer rupture to the thrust faults of the San Gorgonio Pass fault zone. However, under certain assumptions, earthquakes that nucleate along the San Gorgonio Pass fault zone can transfer rupture to the San Bernardino strand.

  9. Fluvial systems response to rift margin tectonics: Makhtesh Ramon area, southern Israel

    NASA Astrophysics Data System (ADS)

    Ben-David, Ram; Eyal, Yehuda; Zilberman, Ezra; Bowman, Dan

    2002-06-01

    The geomorphic evolution of Makhtesh Ramon, a feather-shaped erosional valley, and the Nahal Neqarot drainage system to the south occurred largely in response to tectonic activity along the Dead Sea Rift and its western shoulder. Remnants of Miocene clastic sediments (Hazeva Formation) deposited on an erosional peneplain that formed over this area during the Oligocene epoch provide a datum plane for reconstructing subsequent fluvial evolution. These clastic remnants are presently located on the shoulders of Makhtesh Ramon at various elevations. The peneplain truncating the Makhtesh Ramon block has been tilted 0.7% northeastward since the Pliocene epoch (post-Hazeva Formation), whereas that of the Neqarot syncline, south of the Ramon, has been tilted 1.2%. The elliptical exposure of friable Lower Cretaceous sandstone, exposed in the core of the truncated Ramon structure, governed the development of a new ENE directed (riftward) drainage system through capture of streams that previously drained toward the Mediterranean Sea to the northwest. Incised fluvial gaps in the southern rim of Makhtesh Ramon and alluvial fan relicts within Makhtesh Ramon attest to original drainage into the Makhtesh from the south. Remnants of the Plio-Pleistocene Arava Conglomerate on the eastern end of the Neqarot syncline contain clasts from rocks exposed within Makhtesh Ramon, also indicating that streams flowed into the Makhtesh from the southern Neqarot block through the western gaps, then turning eastward and exiting the Makhtesh via the next (Sha'ar-Ramon) gap to the east. Further down-faulting of the Neqarot block during Mid-Late Pleistocene time led to westward retreat of the Neqarot valley and capture of the last stream flowing northward into the Ramon, leaving the modern Makhtesh Ramon isolated from the southern drainage system.

    2007-01-01

    Ocean Beach in San Francisco, California, contains a persistent erosional section in the shadow of the San Francisco ebb tidal delta and south of Sloat Boulevard that threatens valuable public infrastructure as well as the safe recreational use of the beach. Coastal managers have been discussing potential mediation measures for over a decade, with little scientific research available to aid in decision making. The United States Geological Survey (USGS) initiated the Ocean Beach Coastal Processes Study in April 2004 to provide the scientific knowledge necessary for coastal managers to make informed management decisions. This study integrates a wide range of field data collection and numerical modeling techniques to document nearshore sediment transport processes at the mouth of San Francisco Bay, with emphasis on how these processes relate to erosion at Ocean Beach. The Ocean Beach Coastal Processes Study is the first comprehensive study of coastal processes at the mouth of San Francisco Bay.

  19. Flow patterns of magma in dikes, Makhtesh Ramon, Israel

    SciTech Connect

    Baer, G.; Reches, Z.

    1987-06-01

    Directions of magma flow were measured in a system of radial dikes in Makhtesh Ramon, Israel. The flow directions were determined from field observations of segments, fingers, grooves, and groove molds of the dikes. The study indicates that the mean axis of magma flow is subhorizontal toward the north, in agreement with the direction of divergence of the radial dike system. Two modes of flow were observed: (1) regular, bedding-parallel flow in the well-stratified rock units and (2) irregular, meandering flow in the massive rock units. It is suggested that corrugated dike walls in well-stratified host rocks cause magma channelization, and random or self-generated restrictions in massive host rocks cause the apparent meanders. Furthermore, the major lithologic boundaries in the host units strongly affect segmentation of the dikes.

  13. Dynamic Models of Potential Earthquakes in the San Gorgonio Pass, CA

    NASA Astrophysics Data System (ADS)

    Tarnowski, J. M.; Oglesby, D. D.

    2012-12-01

    We use numerical modeling to investigate the likelihood of a through-going earthquake along the San Andreas fault system in the San Gorgonio Pass (SGP). The SGP is a structurally complex area of Southern California often referred to as a "pinch-point" along the fault system, with several non-vertical and non-coplanar segments. It may or may not be a geometrical barrier that can slow or stop earthquake rupture propagation. The likelihood of through-going rupture in the SGP affects the maximum earthquake size in Southern California as well as the intensity and distribution of ground motion, with implications for seismic hazard. We use the finite element code FaultMod (Barall, 2009) to observe differences in rupture propagation and ground motion based on different input parameters in a simplified fault geometry of the SGP region. This region includes the nearly perpendicular intersection of the right-lateral San Bernardino strand and the San Gorgonio Pass Thrust near Millard Canyon. Models that include the San Bernardino, Garnet Hill, and Coachella Valley fault strands show that near-fault ground motion patterns are heterogeneous with pronounced asymmetry across the fault strands. Ground motion distribution farther from the strands varies with the hypocenter location. In models with faults close to failure, the presence of well-defined Mach cones suggest that non-planar fault strands may not inhibit supershear rupture nor render Mach cones incoherent. The models presented here are the early stages of a series of test cases to develop more realistic models of rupture in the SGP that incorporate the complexity of fault geometry and stress distribution in the region.

  14. Comparison of a few recording current meters in San Francisco Bay, CA

    USGS Publications Warehouse

    Cheng, R.T.

    1978-01-01

    A team of research scientists in the U.S. Geological Survey uses San Francisco Bay, California, as an outdoor laboratory to study complicated interactions of physical, chemical, and biological processes which take place in an estuarine environment. A current meter comparison study was conceived because of the need to select a suitable current meter to meet field requirements for current measurements in the Bay. The study took place in south San Francisco Bay, California, in the spring of 1977. An instrument tower which was designed to support instruments free from the conventional mooring line motions was constructed and emplaced in south San Francisco Bay. During a period of two months, four types of recording current meters have been used in the tests. The four types were: (1) Aanderaa, (2) tethered shroud-impeller, (3) drag-inclinometer, and (4) electromagnetic current meters. With the exception of the electromagnetic current meter, one of each type was mounted on the instrument tower, and one of each type was deployed on moorings near the instrument tower. In addition, a wind anemometer and a recording tide gauge were also installed on the tower. This paper discusses the characteristics of each instrument and the accuracy that each instrument can provide when used in an estuarine environment. We pay special attention to our experiences in the field operation with respect to handling of the instruments and to our experiences working up the raw data in the post-deployment data analysis.

  15. Regional-scale hydrologic modeling of flow and reactive salt transport in the San Joaquin Valley, CA

    A hydro-salinity model was developed to integrate subsurface hydrology with reactive salt transport for a 1,400 km2 study area in the San Joaquin Valley, CA. For the first time, such a modeling framework was used to reconstruct historical changes in salt storage by irrigated agriculture over the past 60 years. We show that patterns in soil and groundwater salinity were caused by spatial variations in soil hydrology, the switching from local groundwater to snowmelt water as the main irrigation water supply, and by occasional droughts. Gypsum dissolution was a critical component of the regional salt balance. Although results show that the total salt input and output were about equal for the past 20 years, the model also predicts salinization of the deeper aquifers, thereby questioning the sustainability of irrigated agriculture.

    Habitat use has been shown to be an important factor in the bioaccumulation of contaminants in striped bass. This study examines migration in striped bass as part of a larger study investigating bioaccumulation and maternal transfer of xenobiotics to progeny in the San Francisco Estuary system. Habitat use, residence time and spawning migration over the life of females (n = 23) was studied. Female striped bass were collected between Knights Landing and Colusa on the Sacramento River during the spawning runs of 1999 and 2001. Otoliths were removed, processed and aged via otolith microstructure. Subsequently, otoliths were analyzed for strontium/calcium (Sr/Ca) ratio using an electron-microprobe to measure salinity exposure and to distinguish freshwater, estuary, and marine habitat use. Salinity exposure during the last year before capture was examined more closely for comparison of habitat use by the maternal parent to contaminant burden transferred to progeny. Results were selectively confirmed by ion microprobe analyses for habitat use. The Sr/Ca data demonstrate a wide range of migratory patterns. Age of initial ocean entry differs among individuals before returning to freshwater, presumably to spawn. Some fish reside in freshwater year-round, while others return to more saline habitats and make periodic migrations to freshwater. Frequency of habitat shifts and residence times differs among fish, as well as over the lifetime of individual fish. While at least one fish spent its final year in freshwater, the majority of spawning fish spent their final year in elevated salinity. However, not all fish migrated to freshwater to spawn in the previous year. Results from this investigation concerning migration history in striped bass can be combined with contaminant and histological developmental analyses to better understand the bioaccumulation of contaminants and the subsequent effects they and habitat use have on fish populations in the San Francisco Estuary system.

    Objective Ciclovía or Open Streets initiatives support physical activity through cycling/rolling, and walking/running. We evaluated San Diego’s first Open Streets event, CicloSDias, to document attendance, reach and marketing, and effects on social cohesion, businesses, and physical activity. Methods The comprehensive evaluation consisted of a city-wide survey 1 week before and after the event (n=805), counts of event attendees, and surveys of event attendees (n=713) and businesses (n=26). Results An estimated 8,311 people attended the event. Attendees had an average of 144 minutes (SD=85) of physical activity, 97% met the 30 minute/day guideline, and 39% met the 150 minute/week guideline during the event. 27% of attendees would have been inactive without the event. Awareness of the event was 10% before and 26% after the event. When comparing event attendees to San Diego residents, Latinos and non-white race/ethnicities were under-represented. Restaurants/pubs, services, and most retail stores excluding liquor stores and food markets reported positive or neutral impacts on business. Conclusion Open Street initiatives are promising ways to promote physical activity and are desired by the community. Positive effects were observed for physical activity, social cohesion, and businesses, though reach should be expanded to include more underserved community members. Evaluating Open Streets is important for sustaining and improving these efforts. PMID:25459488

    2007-01-01

    We analyze seismic data from the San Andreas Fault (SAF) near Parkfield, California, to test for annual modulation in seismicity rates. We use statistical analyses to show that seismicity is modulated with an annual period in the creeping section of the fault and a semiannual period in the locked section of the fault. Although the exact mechanism for seasonal triggering is undetermined, it appears that stresses associated with the hydrologic cycle are sufficient to fracture critically stressed rocks either through pore-pressure diffusion or crustal loading/ unloading. These results shed additional light on the state of stress along the SAF, indicating that hydrologically induced stress perturbations of ???2 kPa may be sufficient to trigger earthquakes.

    In 1908, the San Jacinto Mountains were first surveyed for their animal and plant diversity by Joseph Grinnell and Harry Swarth, Museum of Vertebrate Zoology, UC Berkeley. In 2008, continuing until 2011, the ecology and stable isotope biogeochemistry of the plants, insects, birds, and mammals is being re-surveyed. Results of carbon, nitrogen, and hydrogen isotopes in organic matter show the variation in regional climate and trophic structure. For example, δ15N of plants at more arid stations are more positive by 3-5‰. Plants on westward facing slopes have more negative δ15N (to -6‰) possibly indicating N sources from atmospheric N deposition originating from urban Los Angeles. Isotopic analyses of recent collections will be compared with historic, museum archived specimens of plants and resident birds species. Our initial results show that the carbon isotopic compositions of plants collected in 1908 and during the early part of the 20th century are 1.6‰ enriched in δ13C, as predicted with the rise in industrially influenced atmospheric CO2. Isotopic data will be augmented by species diversity to test the hypothesis that 100 years of human influence has affected the ecosystem in this area and in what manner.

    As part of the NSF-supported Centers for Excellence in Science and Technology (CREST), student and faculty researchers at California State University, Bakersfield (CSUB) have been investigating the regional impacts of climate change as well as evaluating the potential of local contributions to its abatement. Highlights of this research include; 1) the development of a high-resolution climate record from Tulare Lake sediments that spans the past 20,000 years, 2) the quantitative analysis and prediction of climate change impacts on Sierra Nevada snowpack, 3) the detailed subsurface characterization of San Joaquin Valley oilfields targeted for CO2 sequestration, and 4) the evaluation of proposed host rock suitability under simulated CO2 injection conditions. To date, CSUB CREST supported research has resulted in 26 contributions to peer-reviewed journals (currently published or in-review). A primary goal of CSUB CREST is to improve the recruitment, retention, and success of students from the local community, the majority of whom are from backgrounds under-represented in STEM disciplines. More than 28 students have been directly involved in the basic and applied research projects supported by this program. The majority of these students have received, or are on track to receive, an M.S. degree and have ultimately gained employment in a STEM field or been accepted into a Ph.D. program. This presentation, and others in this session, will focus on the accomplishments, challenges, and strategies for success gleaned from CSUB CREST Phase 1.

  6. Rain events in an arid environment — Their distribution and ionic and isotopic composition patterns: Makhtesh Ramon Basin, Israel

    1987-01-01

    Forty-six individual rain events and successive fractions of these events were studied with a network of instruments in the arid Makhtesh Ramon Basin, southern Israel, during 1981/1983 Annual rainfall varied from 47 to 107 mm, number of rain events varied from 8 to 20 per year, start of the rainy season varied from September to January, termination of the rainy season varied from March to May and length of the rainy season varied from 4 to 9 months. About 85% of the rain events were recorded at more than one station, indicating an aerial distribution exceeding 20 km. A cliff amount effect was observed — the rain on the cliff (800 m) was 73% more than the rain at the bottom of the Makhtesh (500 m). Dust samples revealed the following soluble ions (in equivalents): Ca 2+ ≫ Mg 2+ > Na + ≫ K + and HCO -3 > Cl - > SO 2-4. The dust also contained CaCl 2. Rain composition of 61 analyzed samples revealed (in equivalents): Ca 2+ > Na + > Mg 2+ ≫ K + and HCO -3 > Cl - > SO 2-4, neutral pH of 7.1-7.6, and presence of CaCl 2. A similar pattern was observed in 54 samples collected during the same period at Sde Boker, 30 km north of the Ramon, thus typifying the Negev Heights. Two distinct sources of dissolved ions were inferred: dust, providing mainly Ca(HCO 3) 2, and cloud-borne sea spray, providing mainly Na +, Mg 2+, Cl - and SO 2-4. A chemical and isotopic effect was observed — the rain of the rainier year contained 34% less dissolved ions and was isotopically lighter in δ 18O by 54% than the rain of the less rainy year. A chemical and isotopic front effect was observed — the first fraction of the individual rain events contained more dissolved ions (32-69%) and was enriched by more δ 18O (31%) than the subsequent rain fractions. The observed rain distribution and chemical isotopic effects are discussed in terms of input sources, evaporation processes and altitude effects. The obtained data define rain and salt inputs into the hydrological systems.

  7. Estimates of the magnitude of aseismic slip associated with small earthquakes near San Juan Bautista, CA

    Hawthorne, J. C.; Simons, M.

    2013-12-01

    The recurrence intervals of repeating earthquakes raise the possibility that much of the slip associated with small earthquakes is aseismic. To test this hypothesis, we examine the co- and post-seismic strain changes associated with Mc 2 to 4 earthquakes on the San Andreas Fault. We consider several thousand events that occurred near USGS strainmeter SJT, at the northern end of the creeping section. Most of the strain changes associated with these events are below the noise level on a single record, so we bin the earthquakes into 3 to 5 groups according to their magnitude. We then invert for an average time history of strain per seismic moment for each group. The seismic moment M0 is assumed to scale as 10β Mc, where Mc is the preferred magnitude in the NCSN catalog, and β is between 1.1 and 1.6. We try several approaches to account for the spatial pattern of strain, but we focus on the ɛE-N strain component (east extension minus north extension) because it is the most robust to model. Each of the estimated strain time series displays a step at the time of the earthquakes. The ratio of the strain step to seismic moment is larger for the bin with smaller events. If we assume that M0~ 101.5Mc, the ratio increases by a factor of 3 to 5 per unit decrease in Mc. This increase in strain per moment would imply that most of the slip within an hour of small events is aseismic. For instance, the aseismic moment of a Mc 2 earthquake would be at least 5 to 10 times the seismic moment. However, much of the variation in strain per seismic moment is eliminated for a smaller but still plausible value of β. If M0~101.2Mc, the strain per moment increases by about a factor of 2 per unit decrease in Mc.

    Mining, both historic and current, is a source of concern with regard to inputs of Hg into the environment. Active Hg mine sites exist primarily in the Circumpacific and Mediterranean-Himalayan belts and Hg releases are associated with gold mining in the same areas. Sediment cores collected in San Francisco Bay (SFB) and Tomales Bay (TB) show contaminant profiles of Hg and provide a historical perspective on Hg contamination where both Hg mining and gold mining occurred in the watershed. Three sources of input of Hg contamination to SFB can be identified: hydraulic gold mining in the late 1800`s in the Sierra Nevada mountains; Hg mined in the watershed of the South Bay; and industry. Historical sources into TB are limited to inputs from local Hg mining. Pre-anthropogenic concentrations of Hg in both Bays were 0.05 ug/g. Maximum concentrations in TB reached 0.4 {micro}g/g in the upper 40 cm. Maximum concentrations in SFB were {approximately}0.5--1.0 {micro}g/g. The highest concentrations of Hg are buried at 1 m depth in the North Bay cores, suggesting inputs of Hg from mining in the Sierra Nevada mountains during the late 1800`s to early 1900`s. This suggests that modern industrial sources are small compared to the mass of Hg employed by mining. Enriched concentrations of Hg near the mouth of the estuary average about 0.5 {micro}g/g. The difference from upstream is consistent with dilution of contaminated riverine sediment, with clean, marine sediment, as indicated by geologic tracers (Cr and Al) in sediments from the Sierra Nevada Mountain ranges.

    Coastal marine sediments support a high abundance of mircoorganisms which play key roles in the cycling of nutrients, trace metals, and carbon, yet little is known about many of the cofactors essential for their growth, such as the B-vitamins. The suite of B-vitamins (B1, B2, B6, B7, B12) are essential across all domains of life for both primary and secondary metabolism. Therefore, studying sediment concentrations of B-vitamins can provide a biochemical link between microbial processes and sediment geochemistry. Here we present B-vitamin pore water concentrations from suboxic sediment cores collected in September 2014 from San Pedro Basin, a silled, low oxygen, ~900 m deep coastal basin in the California Borderlands. We compare the B-vitamin concentrations (measured via LCMS) to a set of geochemical profiles including dissolved Fe (65-160 μM), dissolved Mn (30-300 nM), TCO2, solid phase organic carbon, and δ13C. Our results show high concentrations (0.8-3nM) of biotin (B7), commonly used for CO2 fixation as a cofactor in carboxylase enzymes. Thiamin (B1) concentrations were elevated (20-700nM), consistent with previous pore water measurements showing sediments could be a source of B1 to the ocean. Cobalamin (B12), a cofactor required for methyl transfers in methanogens, was also detected in pore waters (~4-40pM). The flavins (riboflavin [B2] and flavin mononucleotide[FMN]), molecules utilized in external electron transfer, showed a distinct increase with depth (10-90nM). Interestingly, the flavin profiles showed an inverse trend to dissolved Fe (Fe decreases with depth) providing a potential link to culture experiments which have shown extracellular flavin release to be a common trait in some metal reducers. As some of the first B-vitamin measurements made in marine sediments, these results illustrate the complex interaction between the microbial community and surrounding geochemical environment and provide exciting avenues for future research.

  10. A sediment budget for the southern reach in San Francisco Bay, CA: implications for habitat restoration

    The South Bay Salt Pond Restoration Project is overseeing the restoration of about 6000 ha of former commercial salt-evaporation ponds to tidal marsh and managed wetlands in the southern reach of San Francisco Bay (SFB). As a result of regional groundwater overdrafts prior to the 1970s, parts of the project area have subsided below sea-level and will require between 29 and 45 million m3 of sediment to raise the surface of the subsided areas to elevations appropriate for tidal marsh colonization and development. Therefore, a sufficient sediment supply to the far south SFB subembayment is a critical variable for achieving restoration goals. Although both major tributaries to far south SFB have been seasonally gaged for sediment since 2004, the sediment flux at the Dumbarton Narrows, the bayward boundary of far south SFB, has not been quantified until recently. Using daily suspended-sediment flux data from the gages on Guadalupe River and Coyote Creek, combined with continuous suspended-sediment flux data at Dumbarton Narrows, we computed a sediment budget for far south SFB during Water Years 2009–2011. A Monte Carlo approach was used to quantify the uncertainty of the flux estimates. The sediment flux past Dumbarton Narrows from the north dominates the input to the subembayment. However, environmental conditions in the spring can dramatically influence the direction of springtime flux, which appears to be a dominant influence on the net annual flux. It is estimated that up to several millennia may be required for natural tributary sediments to fill the accommodation space of the subsided former salt ponds, whereas supply from the rest of the bay could fill the space in several centuries. Uncertainty in the measurement of sediment flux is large, in part because small suspended-sediment concentration differences between flood and ebb tides can lead to large differences in total mass exchange.

    Groundwater quality in the ~2,600 km2 North San Francisco Bay groundwater basins was investigated as part of the Priority Basin Project of the GAMA Program, a collaboration of the California State Water Resources Control Board, U.S. Geological Survey and Lawrence Livermore National Laboratory. Samples from 96 wells and 1 hydrothermal spring were analyzed for water chemistry, isotopic abundances, and dissolved gases. The study, designed to provide a spatially unbiased assessment of untreated groundwater quality in the primary aquifer systems, was based on water-quality and ancillary data from 84 of the wells sampled and water-quality data from the California Department of Public Health (CDPH) database. The primary aquifers are defined as those parts of the aquifers corresponding to the perforated intervals of wells listed in the CDPH database. Inorganic constituents with human-health benchmarks were present at high concentrations in 14%, moderate in 35.8%, and low in 50.2% of the primary aquifers. Arsenic, boron, and lead were the trace elements that most frequently occurred at high concentrations. Fluoride is a minor element, and nitrate, a nutrient were present at high concentrations in ~1% of the primary aquifers. In contrast, organic constituents (one or more) with human-health benchmarks were present at high concentrations in 1.4%, moderate in 4.9%, and low in 93.7% (not detected in 64.8%) of the primary aquifers. The high proportion of organic constituents primarily reflected high concentrations of PCE (1.3%), TCE (0.1%), and 1,1-dichloroethene (0.1%). Of the 255 organic constituents analyzed for, 26 constituents were detected. Two organic constituents were frequently detected (detected in 10% or more of samples): the trihalomethane chloroform and the herbicide simazine, but both were detected at low concentrations. In this study, arsenic is the constituent which most frequently exists at high concentrations (about 10%) in the primary aquifers. Natural sources

    The solubility controls on vanadium (V) in groundwater were studied due to concerns over possible harmful health effects of ingesting V in drinking water. Vanadium concentrations in the northeastern San Joaquin Valley ranged from 25 μg/L) and lowest in samples collected from anoxic groundwater (70% 2VO4−. Adsorption/desorption reactions with mineral surfaces and associated oxide coatings were indicated as the primary solubility control of V5+ oxyanions in groundwater. Environmental data showed that V concentrations in oxic groundwater generally increased with increasing groundwater pH. However, data from adsorption isotherm experiments indicated that small variations in pH (7.4–8.2) were not likely as an important a factor as the inherent adsorption capacity of oxide assemblages coating the surface of mineral grains. In suboxic groundwater, accurate SM modeling was difficult since Eh measurements of source water were not measured in this study. Vanadium concentrations in suboxic groundwater decreased with increasing pH indicating that V may exist as an oxycationic species [e.g. V(OH)3+]. Vanadium may complex with dissolved inorganic and organic ligands under suboxic conditions, which could alter the adsorption behavior of V in groundwater. Speciation modeling did not predict the existence of V-inorganic ligand complexes and organic ligands were not collected as part of this study. More work is needed to determine processes governing V solubility under suboxic groundwater conditions. Under anoxic groundwater conditions, SM predicts that aqueous V exists as the uncharged V(OH)3 molecule. However, exceedingly low V concentrations show that V is sparingly soluble in anoxic conditions. Results indicated that V may be precipitating as V3+- or mixed V3+/Fe3+-oxides in anoxic groundwater, which is consistent with results of a previous study. The fact that V appears insoluble in anoxic (Fe reducing) redox conditions indicates that the behavior of V is different than

    Evaporation ponds in the SJV, CA used for the containment of irrigation drainage waters, contain elevated levels of U. The ponds support algae which upon evaporation, become incorporated in sediments as layers of organic matter (OM). The OM facilitates reducing conditions in the sediment. However, our past studies show sediment U exists as primarily the oxidized form, U(VI)--regardless of redox status. Our research was conducted with this pond sediment to further characterize U speciation and the influence of pond algae on sediment U redox chemistry. The research involved techniques such as X-ray absorption spectroscopy, basic and time-resolved luminescence spectrometry in addition to wet chemistry methods. Uranium(VI) reduction in the sediment was observed in the presence of alfalfa (as a microbial energy source) under anaerobic conditions and reduction was not promoted by native pond algae under oxidizing conditions. Sediment U(VI) most likely exists as two groups of luminescent species: U(VI)-oxides/U(VI)-hydroxides and U(VI)-organics.

    Aerosol hygroscopicity was investigated using a novel dryer-humidifier system, coupled to a TSI-3563 nephelometer, to obtain the light scattering coefficient (σscat) as a function of relative humidity (RH) in hydration and dehydration modes. The measurements were performed in Porterville, CA (10 January to 6 February 2013), Baltimore, MD (3-30 July 2013), and Golden, CO (12 July to 10 August 2014). Observations in Porterville and Golden were part of the NASA-sponsored Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality project. The measured σscat under varying RH in the three sites was combined with ground aerosol extinction, PM2.5 mass concentrations, and particle composition measurements and compared with airborne observations performed during campaigns. The enhancement factor, f(RH), defined as the ratio of σscat(RH) at a certain RH divided by σscat at a dry value, was used to evaluate the aerosol hygroscopicity. Particles in Porterville showed low average f(RH = 80%) (1.42) which was attributed to the high carbonaceous loading in the region where residential biomass burning and traffic emissions contribute heavily to air pollution. In Baltimore, the high average f(RH = 80%) (2.06) was attributed to the large contribution of SO42- in the region. The lowest water uptake was observed in Golden, with an average f(RH = 80%) = 1.24 where organic carbon dominated the particle loading. Different empirical fits were evaluated using the f(RH) data. The widely used Kasten (gamma) model was found least satisfactory, as it overestimates f(RH) for RH < 75%. A better empirical fit with two power law curve fitting parameters c and k was found to replicate f(RH) accurately from the three sites. The relationship between the organic carbon mass and the species that are affected by RH and f(RH) was also studied and categorized.

It should be noted that the amount of these minerals (first and second groups) is extremely high: in 200 kg of the investigated geological concentrate (selected from the loose deposits and conglomerate) till the present time (January 2003) altogether were detected more than 14,000 grains of the proposed diamondiferous association. Identification of small plates of Au and Ag as well as tracing of La, Ce, Th, Nb and Ta also maybe linked with the nearest kimberlite rock occurrence. Analysis of the studied polymineral fractions has been performed using electronic scanning raster microscope CAMSCAN-4DV with energy-dispersion Roentgen micro-analyzer Link AN10000 (binocular microscopes were applied only by initial analyzing). Examination of the performed geophysical investigations: (1a) magnetic field (applied ground observations were integrated with the previous airborn measurements), (1b) magnetic susceptibility measurements; (2) self-potential field and (3) set of physical-chemical examinations of significant features (S2+, CO2-_3, Eh{-}Pt, N0^-_3, Br^-, F^-, I^-, Cl^-, Ca2+, B^+, ClO^-_4, pH, Hg2+, Na^+, K^+, Cd2+, Cu2+ &Pb2+) using ion-selective electrodes (gradient mode was applied) testifies to high probability of discovering diamondiferous pipes (dykes) at the depths from several meters up to 30 meters. The latest important petrological identifications include discovering of blue clay (usually occurring at the top of kimberlite pipe) and yttrium phosphate (it is a known signature of kimberlite associations). Finally, the total number of recognized diamonds exceeds 400 units (size of the largest crystal is about of 1.5 mm). On basis of the mentioned positive features we can unambiguously estimating that the Makhtesh Ramon Canyon is highly perspective area for discovering indigenous diamond-containing targets.

    Until recently, active fault zones were thought to deform via seismic slip during earthquakes in the upper, brittle portion of the crust, and by steady, aseismic shear below. However, since 2000, this view has been shaken by seismological observations of seismic tremor deep in the roots of active fault zones, including on the section of the San Andreas to the southeast of Parkfield, CA, deep (~20-30 km) beneath the nucleation zone of the great 1857 Fort Tejon earthquake. With funding from the Gordon and Betty Moore Foundation, we have improved the seismic network in the area above the tremor source by installing four new broadband/strong motion surface stations and four borehole sites with uphole accelerometers and downhole geophones, broadband and strong motion sensors. Data from all stations are telemetered in real-time. They are analysed as part of normal earthquake monitoring, and archived and distributed through the Northern California Earthquake Data Center (NCEDC). Data from the TremorScope project is improving earthquake monitoring in the region south of Parkfield, including allowing empirical Greens function finite fault analysis of moderate events in the area. Locations and characterization of tremor episodes are improved by the data recorded by TremorScope stations. For example, the rate of ambient tremor activity in the TremorScope area increased by a factor of ~8 within ~12 hours of the 2014 Napa M6.0 earthquake and remained elevated for ~ 100 days, exceeding the tremor rate increase following the 2004 Parkfield M6.0 quake despite the differences in epicentral distance (~300 km vs. ~15 km). No comparable increases in tremor rates have been observed between the Parkfield and Napa events. This suggests that the sensitivity to external stressing in the in the deep tremor zone of the TremorScope region may have increased since 2004. We also show how this network's strong motion instrumentation will provide unprecedented and exciting insights into the

  20. Response of deformation patterns to reorganizations of the southern San Andreas fault system since ca. 1.5 Ma

    Between ~1.5 and 1.1 Ma, the southern San Andreas fault system underwent a major reorganization that included initiation of the San Jacinto fault and termination of slip on the extensional West Salton detachment fault. The southern San Andreas fault itself has also evolved since this time, with several shifts in activity among fault strands within San Gorgonio Pass. We use three-dimensional mechanical Boundary Element Method models to investigate the impact of these changes to the fault network on deformation patterns. A series of snapshot models of the succession of active fault geometries explore the role of fault interaction and tectonic loading in abandonment of the West Salton detachment fault, initiation of the San Jacinto fault, and shifts in activity of the San Andreas fault. Interpreted changes to uplift patterns are well matched by model results. These results support the idea that growth of the San Jacinto fault led to increased uplift rates in the San Gabriel Mountains and decreased uplift rates in the San Bernardino Mountains. Comparison of model results for vertical axis rotation to data from paleomagnetic studies reveals a good match to local rotation patterns in the Mecca Hills and Borrego Badlands. We explore the mechanical efficiency at each step in the evolution, and find an overall trend toward increased efficiency through time. Strain energy density patterns are used to identify regions of off-fault deformation and potential incipient faulting. These patterns support the notion of north-to-south propagation of the San Jacinto fault during its initiation. The results of the present-day model are compared with microseismicity focal mechanisms to provide additional insight into the patterns of off-fault deformation within the southern San Andreas fault system.

  1. Cross-shelf transport into nearshore waters due to shoaling internal tides in San Pedro Bay, CA

    In the summer of 2001, a coastal ocean measurement program in the southeastern portion of San Pedro Bay, CA, was designed and carried out. One aim of the program was to determine the strength and effectiveness of local cross-shelf transport processes. A particular objective was to assess the ability of semidiurnal internal tidal currents to move suspended material a net distance across the shelf. Hence, a dense array of moorings was deployed across the shelf to monitor the transport patterns associated with fluctuations in currents, temperature and salinity. An associated hydrographic program periodically monitored synoptic changes in the spatial patterns of temperature, salinity, nutrients and bacteria. This set of measurements show that a series of energetic internal tides can, but do not always, transport subthermocline water, dissolved and suspended material from the middle of the shelf into the surfzone. Effective cross-shelf transport occurs only when (1) internal tides at the shelf break are strong and (2) subtidal currents flow strongly downcoast. The subtidal downcoast flow causes isotherms to tilt upward toward the coast, which allows energetic, nonlinear internal tidal currents to carry subthermocline waters into the surfzone. During these events, which may last for several days, the transported water remains in the surfzone until the internal tidal current pulses and/or the downcoast subtidal currents disappear. This nonlinear internal tide cross-shelf transport process was capable of carrying water and the associated suspended or dissolved material from the mid-shelf into the surfzone, but there were no observation of transport from the shelf break into the surfzone. Dissolved nutrients and suspended particulates (such as phytoplankton) transported from the mid-shelf into the nearshore region by nonlinear internal tides may contribute to nearshore algal blooms, including harmful algal blooms that occur off local beaches.

    Persons who inject drugs (PWID) are at increased risk for blood-borne virus (BBV) infections and overdose resulting from high-risk injecting practices. Studies of prefilled syringe use ([PFSU] using a syringe that already contained drug solution when it was obtained by the user), an injection practice previously described in Eastern Europe, suggest that it increases susceptibility to BBV. However, little is known about this practice in the USA. Data were obtained from an ongoing cohort study of PWID to determine the prevalence and assess correlates of PFSU in San Diego, CA. Baseline interviews assessed socio-demographics and drug use behaviors. Logistic regression was used to identify factors independently associated with ever using a prefilled syringe (yes/no). Participants (n = 574) were predominately males (73.9%) and white (50.9%) with a mean age of 43.4 years (range 18-80); 33.3% reported ever using prefilled syringes, although only 4.9% reported use in the past 6 months. In multivariable analyses, PFSU was independently associated with ever having a rushed injection due to police presence [adjusted odds ratio (AOR) = 2.51, 95% CI 1.66, 3.79], ever being in prison (AOR = 1.80, 95% CI 1.23, 2.63), injecting most often in public versus private places in the past 6 months (AOR = 1.66, 95% CI 1.11, 2.48), and injecting drugs in Mexico (AOR = 1.70, 95% CI 1.16, 2.49). Results indicate that a history of PFSU is common and associated with environmental factors that may also increase risk for adverse health outcomes. Studies are needed to better understand PFSU in order to develop interventions to prevent adverse outcomes associated with their use. PMID:26382653

  4. Impact of Elevated CO2 on Trace Element Release from Aquifer Sediments of the San Joaquin Valley, CA

    Carbon capture and storage (CCS) is a promising technique for mitigating climate change by storing large volumes of carbon dioxide in deep saline aquifers. In California, the thick marine sediments of the Central and Salinas Valleys have been identified as prime targets for future CO2 storage. However, the potential impacts on water quality of overlying drinking-water aquifers must be studied before CCS can be implemented. In this study, we compare trace element release from San Joaquin Valley aquifer sediments with a wide range of textural and redox properties. Kinetic batch experiments were performed with artificial groundwater continuously equilibrated under CO2-saturated (at 1 atm) and background CO2 (0.002-0.006 atm) conditions, resulting in a shift of nearly 3 pH units. In addition, the reversibility of trace element release was studied by sequentially lowering the CO2 from 1.0 atm to 0.5 atm to background concentrations (0.002-0.006 atm) for CO2-saturated systems in order to mimic the dissipation of a CO2 plume in the aquifer. During exposure to high CO2, a number of elements displayed enhanced release compared to background CO2 experiments (Ca, Mg, Li, Si, B, As, Sr, Ni, Fe, Mn, V, Ti, and Co) with concentrations of As, Fe, and Mn exceeding EPA maximum contaminant levels in some cases. On the other hand, Mo and U showed suppressed release. Most intriguing, many of the elements showing enhanced release displayed at least some degree of irreversibility when CO2 concentrations were decreased to background levels. In fact, in some cases (i.e., for V), an element showed further release when CO2 concentrations were decreased. These results suggest that there may be longer-term effects on groundwater quality that persist even after the CO2 plume has dissipated. Several different mechanisms of trace element release including ion exchange, desorption, and carbonate mineral dissolution are explored. Preliminary modeling results suggest that carbonate mineral

    San Diego, California shares the world's busiest land border crossing with Tijuana, Mexico-a city where 95 % of injection drug users (IDUs) test hepatitis C virus (HCV) antibody-positive. Yet, little is known about the prevalence and risk behaviors for HCV among IDUs in San Diego. In 2009-2010, 18-40-year-old IDUs in San Diego County completed a risk assessment interview and serologic testing for HCV and HIV infection. Recruitment involved respondent-driven sampling, venue-based sampling at a syringe exchange program, and convenience sampling. Correlates of HCV infection were identified by multivariable logistic regression. Among 510 current IDUs, 26.9 % (95 % CI 23.0-30.7 %) and 4.2 % (95 % CI 2.4-5.9 %) had been infected with HCV and HIV, respectively. Overall, median age was 28 years; 74 % were male; 60 % white and 29 % Hispanic; and 96 % were born in the U.S. Median years of injecting was 6; 41 % injected daily; 60 % injected heroin most often; 49 % receptively shared syringes and 68 % shared other injection paraphernalia; and only 22 % reported always using new syringes in the past 3 months. Two thirds had ever traveled to Mexico and 19 % injected in Mexico. HCV infection was independently associated with sharing injection paraphernalia (adjusted odds ratio [AOR] = 1.69) and SEP use (AOR = 2.17) in the previous 3 months, lifetime history of drug overdose (AOR = 2.66), and increased years of injecting (AOR = 2.82, all P values <0.05). Controlling for recruitment method did not alter results. HCV infection prevalence among IDUs in San Diego was modest compared to other US cities and much lower than Tijuana. Given that known individual-level HCV risk factors were common in San Diego, the city's lower HCV prevalence might be due to differences in social and structural factors between the cities.

    Mid- to Upper Miocene continental (Orinda and Mulholland Fms.) and shallow marine (Neroly Fm.) strata in the Upper San Leandro Reservoir watershed (SLR) area east of San Francisco Bay preserve important information on structural and landscape evolution during the early phases of strike slip along the Pacific-North American plate boundary. The SLR area lies between the Hayward and Calaveras Faults, major strands of the San Andreas Fault system, and is bisected by the NW-striking Cull Creek Fault (CCF). Geologic mapping delineates five completely intercalated lithofacies in the Mulholland Fm. at SLR. The conglomerate-dominated, sandstone-dominated, and interbedded conglomerate, sandstone, and siltstone facies represent fluvial channel and floodplain deposits; the sandstone + mudstone facies represent lacustrine-deltaic and shallow lacustrine deposits; the shale facies records open lacustrine deposition. Sparse unidirectional paleocurrent indicators show southerly and easterly transport west of the CCF and both westerly and easterly transport east of the CCF. Conglomerate-rich and sand-rich facies tracts are juxtaposed along the CCF. Clast assemblages in Mulholland conglomerates include abundant chart, graywacke, blueschist, and vein quartz, suggesting derivation from a Franciscan-dominated source terrane. Clast assemblages in the gradationally underlying and interfingering Neroly Fm. suggest that it shared the same source terrane; this is atypical for the primarily andesitic (Sierra-derived) Neroly. Fluvial deposits are volumetrically dominant in the Mulholland Fm. at SLR; open-lacustrine shales occur in stratigraphically isolated lenses ranging from > 1 km to < 100 m along strike. This suggests numerous small lakes on a broad drainage plain rather than the single large lake envisioned by previous workers.

    2016-01-01

    New high-resolution CHIRP seismic data acquired offshore San Onofre, southern California reveal that shelf sediment distribution and thickness are primarily controlled by eustatic sea level rise and sediment supply. Throughout the majority of the study region, a prominent abrasion platform and associated shoreline cutoff are observed in the subsurface from ~ 72 to 53 m below present sea level. These erosional features appear to have formed between Melt Water Pulse 1A and Melt Water Pulse 1B, when the rate of sea-level rise was lower. There are three distinct sedimentary units mapped above a regional angular unconformity interpreted to be the Holocene transgressive surface in the seismic data. Unit I, the deepest unit, is interpreted as a lag deposit that infills a topographic low associated with an abrasion platform. Unit I thins seaward by downlap and pinches out landward against the shoreline cutoff. Unit II is a mid-shelf lag deposit formed from shallower eroded material and thins seaward by downlap and landward by onlap. The youngest, Unit III, is interpreted to represent modern sediment deposition. Faults in the study area do not appear to offset the transgressive surface. The Newport Inglewood/Rose Canyon fault system is active in other regions to the south (e.g., La Jolla) where it offsets the transgressive surface and creates seafloor relief. Several shoals observed along the transgressive surface could record minor deformation due to fault activity in the study area. Nevertheless, our preferred interpretation is that the shoals are regions more resistant to erosion during marine transgression. The Cristianitos fault zone also causes a shoaling of the transgressive surface. This may be from resistant antecedent topography due to an early phase of compression on the fault. The Cristianitos fault zone was previously defined as a down-to-the-north normal fault, but the folding and faulting architecture imaged in the CHIRP data are more consistent with a

    The Sharpe Army Depot (SHAD), consisting of 720 acres located in San Joaquin County, California, is on the National Priorities List. The site has served as a storage, receiving, packaging, and shipping facility since 1941. In the late 1940s the Depot also served as a maintenance facility for heavy equipment. Available data indicate that the primary contaminant sources are associated with past heavy equipment and aircraft-maintenance operations. Contaminants associated with SHAD include trichloroethene, arsenic, selenium, and bromacil (a herbicide). The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances via ingestion, dermal contact, or inhalation of contaminants in ground water, subsurface soil, soil-gas, and food-chain entities.

  1. Understanding processes controlling sediment transports at the mouth of a highly energetic inlet system (San Francisco Bay, CA)

    San Francisco Bay is one of the largest estuaries along the U.S. West Coast and is linked to the Pacific Ocean through the Golden Gate, a 100 m deep bedrock inlet. A coupled wave, flow and sediment transport model is used to quantify the sediment linkages between San Francisco Bay, the Golden Gate, and the adjacent open coast. Flow and sediment transport processes are investigated using an ensemble average of 24 climatologically derived wave cases and a 24.8 h representative tidal cycle. The model simulations show that within the inlet, flow and sediment transport is tidally dominated and driven by asymmetry of the ebb and flood tides. Peak ebb velocities exceed the peak flood velocities in the narrow Golden Gate channel as a result of flow convergence and acceleration. Persistent flow and sediment gyres at the headland tips are formed that limit sediment transfer from the ebb-tidal delta to the inlet and into the bay. The residual transport pattern in the inlet is dominated by a lateral segregation with a large ebb-dominant sediment transport (and flow) prevailing along the deeper north side of the Golden Gate channel, and smaller flood dominant transports along the shallow southern margin. The seaward edge of the ebb-tidal delta largely corresponds to the seaward extent of strong tidal flows. On the ebb-tidal delta, both waves and tidal forcing govern flow and sediment transport. Wave focusing by the ebb-tidal delta leads to strong patterns of sediment convergence and divergence along the adjacent Ocean Beach.

    Nitrification is the link between reduced and oxidized forms of inorganic nitrogen, and is therefore a crucial step in the estuarine nitrogen cycle. Ammonia-oxidizing microorganisms catalyze the rate-limiting step of ammonia oxidation to nitrite and thus play key roles in the biogeochemical cycling nutrient-rich estuaries. Yet, few studies have measured nitrification rates in tandem with ammonia oxidizer functional gene (amoA) expression, abundance, and diversity in estuary waters. Here, we present a multi-year data set on the microbial ecology and biogeochemistry of nitrification in the San Francisco Bay-Delta, the largest estuary on the North American west coast, collected throughout all regions of the estuary from 2012 to 2014. Data on microbial community distributions use functional gene-based PCR assays to assess the diversity, abundance, and mRNA expression of ammonia oxidizers, while stable isotope tracer experiments were used to measure nitrification rates. Ammonia-oxidizing archaea (AOA) typically outnumbered ammonia-oxidizing bacteria (AOB) throughout the sampled gradient, though the relative abundance of AOB was often greater in brackish regions. mRNA expression of amoA appeared to largely track DNA abundance, but suggested only a fraction of the ammonia-oxidizing community was typically active. AOA were always numerically dominant in the Sacramento River, where average nitrification rates were highest, suggesting the AOA communities in this river are responsible for a relatively constant nitrification hotspot. Additionally, depth profiles of nitrification rates suggested high biogeochemical activity near the sediment-water interface in samples with abnormally high turbidity, indicating similar but transient nitrification hotspots in bottom waters containing resuspended sediments. This work increases our knowledge of the ecology and dynamics of ammonia oxidizers in the San Francisco Bay-Delta, with time series data allowing for the putative

    Predicting beach response on an event scale is extremely difficult due to highly variable spatial and temporal conditions, lack of data on antecedent beach morphology, generic model shortcomings, and uncertainty of local forcing parameters. Each beach system is unique and classical beach erosion models may not be applicable to many high-energy beaches, especially those receiving large long-period waves. Therefore, developing an empirical model is the best way to predict future beach response at a given site. Based on 12 closely spaced (temporally) GPS topographic surveys during the winter of 2005-2006 at Ocean Beach, in San Francisco, California, we have developed a predictive empirical model that relates sub-aerial beach response to observed wave height, period, and direction. The model will provide important information to coastal managers, who will be able to better predict and mitigate possible loss from a forecasted wave event. Ocean Beach, located immediately south of the Golden Gate in San Francisco, is a high-energy, intermediate- slope beach that is exposed to waves generated in both the North and South Pacific. Winter breaking wave heights frequently reach 4 m and can exceed 7 m, with periods sometimes greater than 20 s. Our observations demonstrate that large seasonal variations in the sub-aerial beach profile are likely forced by several single large wave events. These events have led to the partial destruction of a recreational parking lot at the south end of the beach where an erosion hot spot is currently located, and continued erosion will threaten other parts of public infrastructure. This study, in combination with other ongoing research at Ocean Beach, will provide valuable insight that will not only aid local personnel in their management decisions but also contribute to a better understanding of sediment transport at high-energy beaches.

    Elliot Ahumada, Esosa Oghogho, Samantha Nguyen, Humberto Bracho, Diego Quintero, Ashanti Johnson and Kevin Cuff Lake Merritt is a tidal lagoon in the center of Oakland, California, just east of Downtown. Water quality at Lake Merritt has been a major concern for community members and researchers for many years (Pham 200X). Results of past research lead to recommendations to lengthen a channel that connects Lake Merritt with the San Francisco Bay to improve water flow and quality. In 2012 the City of Oakland responded to these recommendations by initiating the creation of a 230-meter long channel. In conducting our research we use a water quality index that takes into account measurements of pH, temperature, water hardness (dissolved solids), ammonia, salinity, dissolved oxygen, and nitrate. Newly collected data is then compared with that collected by Pham using comparable parameters to assess the impact of recent changes at the Lake on its overall water quality. In addition, we measured the abundance of aquatic species at four different sites within the Lake. Preliminary results suggest that an increase in the abundance of fish and improved overall water quality have resulted from channel extension at Lake Merritt.

    Since 2002 the Careers in Science (CiS) intern program has monitored Ocean Beach in San Francisco, California for the population of Emerita analoga (Pacific Mole Crab) as part of a partnership program with the Long-term Monitoring Program and Experiential Training for Students (LiMPETS). LiMPETS is an organization that conducts citizen science with Bay Area youth such as the CiS interns. We specifically assist in the collection of Pacific Mole Crab population statistics at Ocean Beach during the summer from June through August. The purpose of collecting Pacific Mole Crabs is to monitor Profilicollis spp. (Acanthocephalan parasites) - to which Pacific Mole Crabs serve as intermediate hosts - and to learn more about our environment as Pacific Mole Crabs are indicator species. During our collections at Ocean Beach we record size, sex, and number of individuals at specific transects. We then take a random sample from the day, return to the lab, and record their sizes, sexes, and Acanthocephalan parasite load. The results of the collection and dissections are then entered into the LiMPETS online database for scientist and researchers to use. Our project will focus on correlations relating to the data collected (Pacific Mole Crab population, parasite load, abiotic and biotic factors, et cetera).

    Big Bear Valley (elevation ~2060 m) is situated in the east-west trending San Bernardino Mountains of California, close to the transition between Mediterranean and Mojave Desert ecoregions. Baldwin Lake is the older of two basins occupying the valley, with a sediment sequence that demonstrates a high rate of deposition and an apparent synchronicity with marine isotope and global paleoclimate records. Chronology has been established with both AMS radiocarbon and infra-red stimulated luminescence (IRSL) dates. This offers the potential to further investigate paleoclimate change over the past c. 100 ka for Southern California at a high temporal resolution. Baldwin Lake's basal date of 95.9 +/- 6.7 ka is derived from IRSL on feldspar grains, placing the onset of sedimentation into the modern basin during cool MIS 5(b). Phases of high productivity in the lake, including values of up to 35% total organic matter and marl facies, correlate with warm events MIS 5(a) and MIS 3. Glacial stages are largely defined by inorganic sedimentation, though depositional regime varies between high-energy MIS 5(b) and MIS 4, and a relatively quiescent MIS 2. Future work will reconstruct vegetation change prior to MIS 1, in order to elucidate millennial-scale changes in alpine groundcover and forests in Southern California during these globally pervasive Stages.

    Well-mixed surface water in the restored salt marsh at Crissy Field, Golden Gate National Recreation Area, was found to have high aqueous methylmercury (MeHg) concentrations (>1 ng MeHg / L), despite its sandy substrate and low sediment total mercury (THg) concentrations. We sought to determine a) the extent to which the marsh was a source or a sink of MeHg to San Francisco Bay, b) where and when MeHg is produced within the marsh, and c) the extent to which MeHg concentrations in sediment and water varied with extended multi-week flooding events, impoundments caused by periodic sediment accumulation in the narrow inlet. Because Crissy Marsh is small in size, has a single inlet slough channel, and has a tidally-dominated water budget, we had a unique opportunity to construct a THg and MeHg flux budget for this single well-constrained wetland. A 24-hour sampling event was conducted over a full diurnal tidal cycle during August 2008. Particulate and filter-passing (0.45μm) THg and MeHg concentrations were assessed, in addition to concentrations of chlorophyll-a and total suspended solids. These measurements were coupled to water flux calculations from a USGS-derived hydrodynamic model based on tidal prism relationships at this site. The resulting Hg load calculations demonstrated that for this 24-hour period, the marsh was a net source of dissolved MeHg to the bay and a net sink of particulate THg from the bay. To determine where and when Hg was being methylated within the marsh environment, sediment percent (%) MeHg (a surrogate measure of MeHg production efficiency) was examined for 2 years along 8 transects, seasonally and across three marsh elevations (subtidal, low-intertidal, and high-intertidal). The low-intertidal zone (cordgrass-dominated) had higher sediment %MeHg than the other two elevations. Sediment %MeHg was also higher during summer than during winter, highest at the sediment surface (0-2cm), correlated with sediment organic content, and elevated

    Nitrification is the sole link between nitrogen inputs and losses in marine ecosystems, and understanding the microbial ecology and biogeochemistry of nitrification is therefore crucial for understanding how aquatic ecosystems process nitrogen. Recently-discovered ammonia-oxidizing archaea (AOA), rather than ammonia-oxidizing bacteria (AOB), appear to drive ammonia oxidation in many ecosystems, including much of the ocean. However, few studies have investigated these microbes in estuary waters, despite the fact nitrogen concentrations in estuaries are often far higher than the ocean, and can cause drastic ecological harm. We sought to determine the roles of AOA and AOB in driving pelagic nitrification throughout San Francisco Bay, by combining biogeochemical rate measurements with a suite of measurements of the abundance and diversity of AOA and AOB. It addition to traditional functional gene analyses and high-throughput 16S amplicon sequencing, we developed novel qPCR assays to selectively target the ammonia-oxidizing clades found in this estuary, which gave insights into clade-specific distributional patterns. Our biogeochemical data suggest a sizable fraction of ammonium in the bay is oxidized in the water column, likely by AOA, with nitrification in bottom waters also oxidizing a substantial portion of the ammonium exuded by sediments. Generally, Sacramento River waters and Suisun Bay bottom waters had the highest nitrification rates. AOA outnumbered AOB at most stations, and were present in high abundance at both the marine and freshwater ends of the estuary, while AOB abundance was highest in the low-salinity, brackish regions. Different archaeal clades were found at either end of the estuary, suggesting strong niche partitioning along the salinity gradient, with a third clade present largely in brackish waters. This work helps to assess the ability of ammonia-oxidizing microbes in estuaries to transform nitrogen prior to water discharge into the sea, and

    We present results from a continuous 42 meter deep core through damaged granitoids adjacent to the San Andreas fault near Little Rock Creek. We employed several methods to measure particle size distribution (pipette, elutriator, laser particle analyzer), as well as x-ray diffraction and fluorescence (XRD, XRF) methods to investigate the relation between depth, pulverization and chemical processes that may affect the degree of damage. The drill site is characterized by extensive outcrops of granitic rocks with varying degrees of damage at distances of up to a few hundreds of meters from the fault's primary active strand. The drill core is composed mainly of pulverized granite and granodiorite, and crosses several high clay content secondary shears. Results of particle size distributions measured using standard sieving and pipette methods indicate that medium to coarse silt and fine sand are the dominant particle size range in the cored section, similar to pulverized granitic rocks analyzed by Rockwell et al. (2008). Very few clay-size particles were observed, but minor amounts of clay weathering products are present. We observe a minor shift in the particle size distribution towards finer sizes with depth, in agreement with the results of Anderson et al. (1980), and find somewhat different distributions for different lithologies. Several zones displaying significant chemical alteration were captured over the cored interval, but XRF data indicate that there is no systematic change in chemical alteration with depth. Where substantial chemical alterations do occur, different lithologies show different weathering trends. Those chemical alterations occur in proximity to secondary shears, suggesting fluid induced mass transfer.

    Draining peatlands for agricultural cultivation creates an ecosystem shift with some of the fastest rates and largest magnitudes of carbon loss attributable to land-use change, yet peatland drainage is practiced around the world due to the high economic benefit of fertile soil. The Sacramento-San Joaquin Delta in California was drained at the end of the 19th century for agriculture and human settlement, and as a result, has lost 5-8m of peat soil due to oxidation. To reverse subsidence and capture carbon, there is increasing interest in converting drained agricultural land-uses back to flooded conditions to inhibit further peat oxidation. However, this method remains relatively untested at the landscape-scale. This study analyzed the short-term effects of drained to flooded land-use conversion on the balance of carbon, water, and energy over two years at two landscapes in the Delta. We used the eddy covariance method to compare CO2, CH4, H2O, and energy fluxes under the same meteorological conditions in two different land-use types: a drained pasture grazed by cattle, and a flooded newly-converted rice paddy. By analyzing differences in the fluxes from these two land-use types we determined that water management and differences in the plant canopy both play a fundamental role in governing the seasonal pattern and the annual budgets of CO2 and CH4 fluxes at these two sites. While the pasture was a source of carbon to the atmosphere in both years, the rice paddy captured carbon through NEE, even after considering losses from CH4. Especially during the fallow winter months, flooding the soil at the rice paddy inhibited loss of CO2 through ecosystem respiration when compared with the carbon exchange from the drained pasture.

    Sieh and Jahns (S&J) (1984) reported a slip rate of 33.9 +2.9 mm/yr for the San Andreas fault (SAF) at Wallace Creek (WC) in the Carrizo Plain. Referenced hundreds of times, their measurement provides critical constraint for many related studies. Paleoseismologic studies at Bidart Fan (BF), ~5 km southeast of WC, show rupture approximately every 88 yrs between ~A.D. 1350 and 1857 (Akciz et al., 2010). Measurements of slip per event for the last 5 or 6 earthquakes at WC (Liu et al., 2004; Liu-Zeng et al., 2006), when combined with rupture dates from BF, yield slip rates up to 50 mm/yr, well above widely accepted values of ~ 35 mm/yr. The apparent discrepancy between slip rates and slip per event measurements provided motivation to re-measure S&J's (1984) slip rate, which was based on 8 detrital charcoal samples, by collecting samples for radiocarbon dating with new methods that have improved dramatically since the early 1980s. We re-excavated S&J's (1984) original trenches WC-2, 7, 9, 10 and 11, and placed a new trench, WC-12. The new trench exposed a rich history of channel cut and fill prior to abandonment of the beheaded channel and incision of the modern channel. The youngest channel fills, which must be slightly younger than the abandonment, indicate that sedimentation occurred between 3675-3285 BP, after which the channel was fully abandoned. Using S&J's (1984) offset measurement of 130 m since ~3400 BP, we recalculate a late Holocene slip rate of ~38 mm/yr in our preliminary analysis. This rate is slightly higher than the S&J (1984) result of 33.9±2.9 mm/yr and Noriega et al. (2006) result of 32.4±3.1 mm/yr at the Van Matre Ranch in the southern Carrizo. Our results are closer to the higher end of the ~36±2 mm/yr velocity gradient across the SAF from decadal timescale geodetic measurements (Schmalzle, et al., 2006).

    The American Association of Pharmaceutical Scientists (AAPS) National Biotechnology Conference Short Course "Translational Challenges in Developing Antibody-Drug Conjugates (ADCs)," held May 24, 2012 in San Diego, CA, was organized by members of the Pharmacokinetics, Pharmacodynamics and Drug Metabolism section of AAPS. Representatives from the pharmaceutical industry, regulatory authorities, and academia in the US and Europe attended this short course to discuss the translational challenges in ADC development and the importance of characterizing these molecules early in development to achieve therapeutic utility in patients. Other areas of discussion included selection of target antigens; characterization of absorption, distribution, metabolism, and excretion; assay development and hot topics like regulatory perspectives and the role of pharmacometrics in ADC development. MUC16-targeted ADCs were discussed to illustrate challenges in preclinical development; experiences with trastuzumab emtansine (T-DM1; Genentech) and the recently approved brentuximab vedotin (Adcetris; Seattle Genetics) were presented in depth to demonstrate considerations in clinical development.

    Hydrocarbon contaminants are ubiquitous in urban aquatic ecosystems, and the ability of some microbial strains to degrade certain polycyclic aromatic hydrocarbons (PAHs) is well established. However, detrimental effects of petroleum hydrocarbon contamination on nondegrader microbial populations and photosynthetic organisms have not often been considered. In the current study, fatty acid methyl ester (FAME) biomarkers in the sediment record were used to assess historical impacts of petroleum contamination on microbial and/or algal biomass in South San Francisco Bay, CA, USA. Profiles of saturated, branched, and monounsaturated fatty acids had similar concentrations and patterns downcore. Total PAHs in a sediment core were on average greater than 20× higher above ∼200 cm than below, which corresponds roughly to the year 1900. Isomer ratios were consistent with a predominant petroleum combustion source for PAHs. Several individual PAHs exceeded sediment quality screening values. Negative correlations between petroleum contaminants and microbial and algal biomarkers - along with high trans/cis ratios of unsaturated FA, and principle component analysis of the PAH and fatty acid records - suggest a negative impacts of petroleum contamination, appearing early in the 20th century, on microbial and/or algal ecology at the site.

    Coastal managers have faced increasing pressure to manage their resources wisely over the last century as a result of heightened development and changing environmental forcing. It is crucial to understand seasonal changes in beach volume and shape in order to identify areas vulnerable to accelerated erosion. Shepard (1950) was among the first to quantify seasonal beach cycles. Sonu and Van Beek (1971) and Wright et al. (1985) described commonly occurring beach states. Most studies utilize widest spaced 2-D cross shore profiles or shorelines extracted from aerial photographs (e.g. Winant et al. 1975; Aubrey, 1979, Aubrey and Ross, 1985; Larson and Kraus, 1994; Jimenez et al., 1977; Lacey and Peck, 1998; Guillen et al., 1999; Norcorss et al., 2002) to analyzed systematic changes in beach evolution. But with the exception of established field stations, such as Duck, NC (Birkemeier and Mason, 1984), ans Hazaki Oceanographical Research Station (HORS) in Japan (Katoh, 1997), there are very few beach change data sets with high temporal and spatial resolutions (e.g. Dail et al., 2000; Ruggiero et al., 2005; Yates et al., in press). Comprehensive sets of nearshore morphological data and local in situ measurements outside of these field stations are very rare and virtually non-existent high-energy coasts. Studied that have attempted to relate wave statistics to beach morphology change require some knowledge of the nearshore wave climate, and have had limited success using offshore measurement (Sonu and Van Beek, 1971; Dail et al., 2000). The primary objective of this study is to qualitatively compare spatially variable nearshore wave predictions to beach change measurements in order to understand the processes responsible for a persistent erosion 'hotspot' at Ocean Beach, San Francisco, CA. Local wave measurements are used to calibrate and validate a wave model that provides nearshore wave prediction along the beach. The model is run for thousands of binned offshore wave

    The San Diego/Tijuana US-Mexico border crossing at the San Ysidro Port of Entry (POE) is the world's busiest international land border crossing (GSA, 2013). San Ysidro, California, is the US community immediately adjacent to the border crossing. More than 90% of San Ysidro residents are Hispanic, and the average household income is less than 60% of the San Diego regional average. This study investigated the San Ysidro POE as a source of traffic-related air pollutants in San Ysidro, especially in relation to wind direction and northbound vehicle wait times. The pollutants ultrafine particulate matter (UFP), black carbon (BC), and particulate matter <2.5 μm in diameter (PM2.5) were periodically sampled through the course of 2010 at four rooftop locations: one commercial establishment near the POE, two elementary schools in San Ysidro, and a coastal estuary reference site. Weather data from two nearby sites and northbound border wait times were also collected. Results indicate consistently higher daytime BC and UFP concentrations at the measurement sites near the POE. Pollution concentrations were higher during low wind speeds or when wind was blowing from the POE towards San Ysidro. In February, March and November measurements, black carbon pollution appeared to be significantly positively associated with the POE northbound wait times when the wind direction was blowing from the POE towards San Ysidro or during low wind speeds, but not when the wind direction was from the west/northwest towards the POE. This pilot study is the first to investigate the potential effect of the POE, especially the long northbound traffic delays, on the nearby community of San Ysidro. Disparities in traffic exposures are an environmental justice issue and this should be taken into account during planning and operation of POEs.

  9. Influence of Wildfire-Created Hydrophobicity on Watershed Flow Paths and Surface Water Quality in City Creek, San Bernardino Mountains, CA

    Wildfires alter surface water quality by changing the physical hydrology and biogeochemical interactions in a watershed. Lignin and other waxy organic compounds vaporize during intense fires. Recondensation of these waxy compounds form coatings on soil particles, which can create a hydrophobic layer. The presence of a hydrophobic layer changes flow paths to the stream channel by increasing overland flow and decreasing flow to subsurface reservoirs. Stream water chemistry is altered by the change in flow paths, as overland flow has shorter travel and mineral/vegetation interaction times than subsurface pathways. Nitrogen, sulfur, potassium and carbon are affected by burning the vegetation. The stream water temporarily receives increased fluxes of these solutes after storm events. Post-fire changes in vegetation also contribute to changes in water quality. The 21 square mile City Creek watershed, located in the San Bernardino Mountains, CA, was burned by the Old Fire in fall 2003. A recently developed air permeameter technique was used to estimate the hydrophobicity of the burned soils. The air permeability was determined by measuring the flow rate and change in pressure and by using the equation: Kair = [(flow rate)(air viscosity)(length of sample)]/[(change in pressure)(area of sample)]. Air permeability was correlated to soil hydraulic conductivity by a relationship developed in previous studies: Log (Ksat)= 1.27 x log(Kair) + 14.11. Vegetation in City Creek watershed consists of chaparral, woodland and conifer forests, with the greatest increases of hydrophobicity in the chaparral. Increased hydrophobicity in the City Creek watershed increased the contribution of overland flow to City Creek, as indicated by the decrease in delta-18O during storm events. This approximately 2 per mil decrease in delta-18O is indicative of the direct influence of precipitation and overland flow on the stream, rather than the continuous groundwater contribution during baseflow

  10. Decadal to Multi-centennial SST Reconstructions From the Anthropocene Into the Last 2 Millennia: Planktonic Foraminiferal Mg/Ca Evidence From San Lazaro Basin (NE Pacific)

    On inter-annual time scales, the El Niño / Southern Oscillation (ENSO) climatic phenomenon is the largest driver of change in the ocean-atmosphere system. Significant impacts also arise from longer-term phenomena at decadal to centennial timescales, such as the Pacific Decadal Oscillation (PDO). It is a primary interest to understand how modern global warming has impacted such drivers of significant climatic impacts, and how the marine sedimentary archive records this linkage in the southern California Current (CC). This would allow detailed comparison against other high-resolution archives, such as corals, and an improved ability to interpret past events as potential analogs for the future of ENSO and PDO. Furthermore, such reconstructions in recent millennia are crucial, since they record pre-anthropogenic climates under interglacial (warm) boundary conditions that allow us to characterize the nature of modern influence on this system. Here we present sub-decadal reconstructions of sea surface temperature (SST), derived from the Mg/Ca ratio of the shallow-dwelling planktonic foraminifera Globigerinoides ruber. The samples come from San Lázaro Basin in the southern Baja California continental margin (25°N; 112°W), situated beneath the dynamic boundary of the cool eastern Pacific boundary CC of northern origin, and the warm subtropical water masses of southern origin. The bottom of this coastal basin (maximum depth of 540m) is bathed by oxygen-depleted waters that flow over a shallow sill at 370m. High levels of primary production and export of biogenic particles to depth ensue from strong seasonal upwelling processes during spring to early summer. This combination of high sediment production and preservation in an area very sensitive to ENSO and PDO impacts allows for a high-resolution reconstruction of inter-annual climatic phenomena in this unique eastern boundary current setting. For our highest temporal detail, we examine 2 cores at interannual resolution

    This Interim Record of Decision (ROD) addresses the contamination at the Puente Valley Operable Unit (PVOU) located within the San Gabriel Valley Superfund Site in Los Angeles County, California. This ROD addresses ground water contaminated with volatile organic compounds (VOCs). The selected remedy is containment of ground water contaminated with VOCs in the shallow and intermediate zones at the mouth of Puente Valley to prevent further migration of existing ground-water contamination. This remedy includes performance criteria that will require extraction and treatment of contaminated ground water at certain locations along the downgradient edge of the contamination and will require continued monitoring and evaluation at other locations. Treated ground water will be provided to local water purveyors or discharged to Puente Creek, immediately upstream of San Jose Creek. In addition, this remedy includes monitoring in the shallow, intermediate, and deep ground-water zones at mid-valley and at the mouth of the valley.

  20. Northern San Andreas Fault slip rates on the Santa Cruz Mountain section: 10Be dating of an offset alluvial fan complex, Sanborn County Park, Saratoga, CA

    To better assess seismic hazard and fault behavior along the southern peninsula in the San Francisco Bay Area on the Santa Cruz Mountain section of the San Andreas Fault, we combine field observations and high-resolution lidar topography data with 10Be exposure dating on offset landforms to estimate geologic fault slip rates. Our mapping at Sanborn County Park near Saratoga reveals a progression of alluvial fans and debris flows offset from their upstream sources by dextral slip on the San Andreas Fault. These upstream sources are 3 drainages, Todd Creek, Service Road Creek and Aubry Creek. Coarse alluvial deposits from each of these creeks contain large Tertiary sandstone boulders of varying size and abundance, derived from the Vaqueros Formation, that allow us to constrain the provenance of offset alluvial deposits to their upstream sources. Initial reconstruction, based on clast-count data on lithology and size from Todd Creek (n=68), Service Road Creek (N=32) and the offset deposits (n=68), suggest ≥140 m of dextral fault movement. Initial 10Be cosmogenic dating of sandstone boulders on an offset deposit from Service Road Creek yields a maximum date of 8 ka, a date uncorrected for hillslope residence and fluvial transport of inherited 10Be concentrations. These data suggest a minimum slip rate of at least 17 mm/yr on the Santa Cruz Mountain section of the San Andreas Fault in the peninsula. Ongoing analysis will refine this fault slip rate. Our preliminary data underscore the potential of this site to provide geologic slip rate estimates, and therefore answer a question critical to seismic hazard assessment, in a region where steep terrain, mass wasting, vegetation and urban development have generally made slip rate estimates challenging to obtain.

    Concentrations of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) were measured in 169 avian eggs. We analyzed randomly collected eggs of two species of piscivorous birds: Caspian tern (Sterna caspia) (n=78) and Forster's tern (Sterna forsteri) (n=76). We also analyzed fail-to-hatch eggs from two species protected under the Federal Endangered Species Act of 1973, that breed in the San Francisco Bay region: the piscivorous California Least tern (Sterna antillarum brownii) (n=11) and the omnivorous California Clapper rail (Rallus longirostris obsoletus) (n=4). San Francisco Bay eggs were collected annually for four years (2000-2003), and additional 20 eggs were collected and analyzed from Gray's Harbor, Washington in 2001. Geometric mean PBDE concentrations did not significantly differ in the three tern species, but concentrations in eggs from the fail to hatch California Clapper rail eggs were significantly lower than those found in the randomly collected tern eggs. Median concentrations of SigmaPBDEs in Caspian tern eggs for 2000-2003 were 2410, 4730, 3720 and 2880 ng/g lipid weight (lw), respectively, in Forster's terns 1820, 4380, 5460 and 3600 ng/g lw, respectively, and in California Least terns for 2001 and 2002 were 5060 and 5170 ng/g lw, respectively. In contrast, median SigmaPBDEs concentration in California Clapper rail eggs for 2001 was 379 ng/g lw. Five PBDEs were the major congeners found and decreased in the order BDE-47, -99, -100, -153, and -154. BDE-32, -28, -71, -66, -85, -183 were less prevalent, minor congeners, as was BDE-209, which was measured in a subset of samples. PBDE concentrations in bird eggs from San Francisco Bay were site related. There was no significant difference in PBDE concentrations in Caspian tern eggs from San Francisco Bay and Gray's Harbor, WA. Average PBDE concentrations in eggs did not significantly increase over the period 2000-2003. PMID:18466953

    Deadwood tree stems scattered above treeline on tephra-covered slopes of Whitewing Mtn (3051 m) and San Joaquin Ridge (3122 m) show evidence of being killed in an eruption from adjacent Glass Creek Vent, Inyo Craters. Using tree-ring methods, we dated deadwood to AD 815-1350 and infer from death dates that the eruption occurred in late summer AD 1350. Based on wood anatomy, we identified deadwood species as Pinus albicaulis, P. monticola, P. lambertiana, P. contorta, P. jeffreyi, and Tsuga mertensiana. Only P. albicaulis grows at these elevations currently; P. lambertiana is not locally native. Using contemporary distributions of the species, we modeled paleoclimate during the time of sympatry to be significantly warmer (+3.2°C annual minimum temperature) and slightly drier (-24 mm annual precipitation) than present, resembling values projected for California in the next 70-100 yr.

  16. Fault-Bounded Late Neogene Sedimentary Deposits in the Santa Rosa Mountains, Southern CA: Constraints on the Evolution of the San Jacinto Fault

    In the Santa Rosa Mountains (SRM) on the W side of the Salton Trough, a late Neogene sedimentary sequence (Zosel sequence, ZS) in the hanging wall of the E-dipping Zosel normal fault (ZFHW) has implications for the geologic history of the southern San Andreas Fault (SAF) system. The upper conglomeratic part of the ZS records the culmination of slip on the ZF, which preceded strike-slip faulting on the right-lateral San Jacinto Fault (SJF) a few km to the W. The conglomerate is an alluvial-fan complex of fluvial, debris-flow, and rock-avalanche deposits that prograded NE over underlying paralic and marine deposits. Clasts are ?10m, and fluvial imbrications indicate mean streamflow trending ~N30E; paleocurrent indicators and clast compositions suggest sediment was derived mainly from granitoid terrains SW of the SRM. Deposition appears to have ceased by early Quaternary time: cosmogenic analysis of boulders from the eroded upper surface of the ZS indicates min and max exposure ages of 500Ka and 1.3Ma (Ne in qtz), 514Ka to 1.17Ma (Ne in hbl), and 647Ka to 1.158Ma (He). Granitoid clasts include distinctive texturally massive hbl- bio tonalite unlike any basement rock exposed in the SRM or in other footwall crystalline terranes directly to the W. The tonalite clasts are similar to bedrock in the White Wash (WW) area 24 km to the NW on the W side of the Clark strand of the SJF (SJFC). Initial Sr ratios for WW samples range from 0.70622 to 0.70631; ZS clasts range from 0.70615 to 0.70638. One sample from ZS and WW have identical light REE patterns that appear to be unique in the Peninsular Ranges batholith. U/Pb zircon ages for WW samples range from 96.6 to 98.2Ma while ZS clasts range from 95.8 to 98.7Ma. Based on these data, tonalite clasts in the ZS match tonalite now exposed in the WW area. We propose the following reconstruction: (1) From 6Ma to 1.2Ma, Zosel sediment is deposited near sea level as an alluvial-fan and fan-delta complex interfingering NE-ward with

    The Loma Prieta slate (LPS) is a <100 m thick slice of highly flattened and stretched, pebbly to shaly metasedimentary rocks exposed for a length of 700 m at Loma Prieta Peak, east of the San Andreas fault in the southern Santa Cruz Mountains. The LPS occurs along a low-dipping segment of the NW-trending, dextral-reverse Sargent fault, which places the slate and overlying Middle Jurassic Coast Range Ophiolite in the hanging wall, eastward over lower Eocene strata. The LPS and overlying Coast Range Ophiolite, in turn, form the base of a 60-80 km long fault block east of the San Andreas fault, overlain by Jurassic-lower Miocene marine strata that together define the Sierra Azul structural block (SAB). These rocks overlie terranes of the Franciscan Complex. The Sargent fault bisects the SAB section and is truncated along-strike and at depth, by the San Andreas fault. Reconstituted clastic grains of the LPS have dominant rhyo-dacitic and granitic sources and felsitic to granophyric grains preserve K-feldspar. Newly crystallized phengitic mica, chlorite and speculatively, incipient pumpellyite, are present in the LPS. No new high P/T metamorphic minerals are petrographically discernible, seemingly distinguishing the LPS from known cataclastic Franciscan Complex rocks structurally beneath the SAB. The LPS instead, has been proposed to correlate with the Jurassic arc-derived Mariposa Formation (MFS) in the Sierra Nevada Foothills, metamorphosed during the Nevadan orogeny. The correlation, however, has been problematic due to a lack of age control on the LPS, its limited surface distribution and its wide separation from the MFS. To test the correlation, we dated detrital zircons from the LPS at University of Arizona's LA-ICPMS lab and compared the results with detrital zircon data from the MFS (Snow and Ernst, 2008, GSA Special Paper 438). Weighted mean age calculations indicate a youngest zircon age cluster at about 152.5±2 Ma for the LPS, which indicates its maximum

    The purpose of this study was to determine how vertical accretion rates in marshes vary through the millennia. Peat cores were collected in remnant and drained marshes in the Sacramento-San Joaquin Delta of California. Cubic smooth spline regression models were used to construct age-depth models and accretion histories for three remnant marshes. Estimated vertical accretion rates at these sites range from 0.03 to 0.49 cm year-1. The mean contribution of organic matter to soil volume at the remnant marsh sites is generally stable (4.73% to 6.94%), whereas the mean contribution of inorganic matter to soil volume has greater temporal variability (1.40% to 7.92%). The hydrogeomorphic position of each marsh largely determines the inorganic content of peat. Currently, the remnant marshes are keeping pace with sea level rise, but this balance may shift for at least one of the sites under future sea level rise scenarios.

  19. Waves and tides responsible for the intermittent closure of the entrance of a small, sheltered tidal wetland at San Francisco, CA

    Crissy Field Marsh (CFM; http://www.nps.gov/prsf/planyourvisit/crissy-field-marsh-and-beach.htm) is a small, restored tidal wetland located in the entrance to San Francisco Bay just east of the Golden Gate. The marsh is small but otherwise fairly typical of many such restored wetlands worldwide. The marsh is hydraulically connected to the bay and the adjacent Pacific Ocean by a narrow sandy channel. The channel often migrates and sometimes closes completely, which effectively blocks the tidal connection to the ocean and disrupts the hydraulics and ecology of the marsh. Field measurements of waves and tides have been examined in order to evaluate the conditions responsible for the intermittent closure of the marsh entrance. The most important factor found to bring about the entrance channel closure is the occurrence of large ocean waves. However, there were also a few closure events during times with relatively small offshore waves. Examination of the deep-water directional wave spectra during these times indicates the presence of a small secondary peak corresponding to long period swell from the southern hemisphere, indicating that CFM and San Francisco Bay in general may be more susceptible to long period ocean swell emanating from the south or southwest than the more common ocean waves coming from the northwest. The tidal records during closure events show no strong relationship between closures and tides, other than that closures tend to occur during multi-day periods with successively increasing high tides. It can be inferred from these findings that the most important process to the intermittent closure of the entrance to CFM is littoral sediment transport driven by the influence of ocean swell waves breaking along the CFM shoreline at oblique angles. During periods of large, oblique waves the littoral transport of sand likely overwhelms the scour potential of the tidal flow in the entrance channel.

  1. Seismic and Aseismic Slip on the San-Jacinto Fault Near Anza, CA, from Joint Analysis of Strain and Aftershock Data

    The San-Jacinto Fault (SJF) is the most active fault in southern California, which together with the southern San-Andreas Fault accommodates a large fraction of the motion across the plate boundary. Seismicity along the SJF is distributed over several fault segments with distinct spatio-temporal characteristics. One of these segments, known as the Anza seismic gap, is a 25 km long strand almost devoid of seismicity. In recent years, four M4-5 events occurred SE of the gap. Despite their moderate magnitudes, these earthquakes triggered rich aftershock sequences and pronounced afterslip that lasted for several weeks, and was well captured by nearby PBO borehole strain meters. A similar transient was remotely triggered by the 2010 El Mayor-Cucapah earthquake. Geodetic and seismic observations following a local M5.4 mainshock indicate that afterslip propagated unilaterally towards the NW at speed of about 5 km/day. We infer the distribution of slip via a joint inversion of the aftershock and strain data. Our approach is based on Dieterich's (1994) model relating the evolution of seismicity rate to applied stresses, within the framework of rate-and-state friction. This approach provides resolution power at depths inaccessible to the surface geodetic network. Moreover, it allows us to gain important insights onto the fault mechanical properties. We apply this inversion scheme to episodes that occurred during 2010. Remarkably, we find that the cumulative moment released post-seismically during the locally triggered transient is 5-10 times larger than the moment of the mainshock. We show that the data favour a model in which deep slip transients, which may develop due to local or remote earthquakes, occur on a weak, close-to-velocity-neutral fault. The transients increase the stress along the Anza gap, and trigger earthquakes outside it through static stress transfer.

    This special issue contains selected contributions from invited speakers to the 'Polycrystal Modelling with Experimental Integration: A Symposium Honoring Carlos Tomé', held as part of the 2011 TMS Annual Meeting and Exhibition, that took place on February 27-March 3, 2011 in San Diego, CA, USA. This symposium honored the remarkable contributions of Dr Carlos N Tomé to the field of mechanical behavior of polycrystalline materials, on the occasion of his 60th birthday. Throughout his career, Dr Tomé has pioneered the theoretical and numerical development of models of polycrystal mechanical behavior, with emphasis on the role played by texture and microstructure on the anisotropic behavior of engineering materials. His many contributions have been critical in establishing a strong connection between models and experiments, and in bridging different scales in the pursuit of robust multiscale models with experimental integration. Among his achievements, the numerical codes that Dr Tomé and co-workers have developed are extensively used in the materials science and engineering community as predictive tools for parameter identification, interpretation of experiments, and multiscale calculations in academia, national laboratories and industry. The symposium brought together materials scientists and engineers to address current theoretical, computational and experimental issues related to microstructure-property relationships in polycrystalline materials deforming in different regimes, including the effects of single crystal anisotropy, texture and microstructure evolution. Synergetic studies, involving different crystal plasticity-based models, including multiscale implementations of the latter, and measurements of global and local textures, internal strains, dislocation structures, twinning, phase distribution, etc, were discussed in more than 90 presentations. The papers in this issue are representative of the different length-scales, materials, and experimental and

  3. Variable earthquake recurrence on the Northern San Andreas fault over the past 3,000 years at the Vedanta marsh site, Olema, CA (Invited)

    The Vedanta marsh trench site is located along the San Andreas fault (SAF) near the town of Olema approximately 45 km north of San Francisco. Excavations into the Vedanta marsh provided exposures of the sediment across the SAF zone that preserves a nearly continuous earthquake record over the past 3,000 years. Evidence for thirteen earthquakes was identified from the main fault zone based on fault outward splays, fault upward terminations, fissures, colluvial wedges, and soft-sediment deformation. The deposits exposed in the trenches contain abundant organic material including peat, charcoal, and macrofossils such as wood, twigs, and leaves. In order to constrain the age of the deposits and prehistoric earthquakes, we radiocarbon-dated 132 samples. Many of the layers in the marsh contain organic materials with ages that range from hundreds to several thousands of years. Except for the peat that accumulates in-situ, most of the organic materials are detrital, washed in from the surrounding forests with long-lived species such as Douglas fir trees that grow to 400 years old. The age of the pre-1906 seismic events are defined by an age model using the OxCal radiocarbon analysis program. This model incorporated 66 of the original 132 dates, about one-half which is common for studies using dates on detrital materials. The paleoseismic record is most complete for the youngest seven earthquakes where faulting was documented in the upper portion of multiple trench exposures. The penultimate event likely occurred sometime during the interval of AD 1650-1735. The average recurrence interval for the past 1,000 years for the youngest seven earthquakes is ~ 140 years with a range of 79 to 220 years. However, when we consider the stratigraphic section back to approximately 1000 B.C., the longest recurrence time between the mean age of the seismic events is 488 years and the shortest is 40 years. These data yield an average earthquake recurrence time of about 240 years. Either

    The California Air Resources Board (CARB) has been operating the Aircraft Pilot Observation (APOB) campaign since 2008 to measure ozone in the upper air, mostly in the residual layer, with an objective to understand the impact of residual layer ozone on daily surface ozone concentrations in the San Joaquin Valley (SJV) where both federal and state standards are often violated. A contracted flight operates daily between 5 - 6 AM over Fresno during the summer months from June - September, and makes continuous measurements of ozone throughout the residual layer up to ~3000 m above ground. The objectives of the current study are to 1) examine the correlation between the residual layer ozone and the surface level 1-hr and/or 8-hr maximum ozone concentrations by analyzing the 2008 - 2013 APOB dataset, and 2) evaluate an air quality model's ability to capture vertical ozone profiles, especially in the residual layer, by comparing the modeling results with the measurements. Preliminary analysis shows that the summertime annual median ozone in the residual layer (between 150 - 3000 m above ground) has decreased by approximately 36% over the 2008 - 2013 period. The time series of daily 1-hr and 8-hr maximum ozone concentrations at a downtown Fresno monitoring site, and daily maximum ozone concentrations in the residual layer show similar patterns, although ozone in the residual layer shows stronger decreasing trends compared to the surface measurements. This, perhaps, indicates that the ozone in the residual layer over Fresno contains contributions from surrounding areas during the daytime. In addition, the ozone trend in the residual layer follows a similar decreasing trend as the reduction of basin-wide emissions of ozone precursors such as NOx and VOCs, which have decreased by 31% and 8%, respectively over the 2005 - 2010 period. The US EPA's CAMQ model will be utilized to model ozone concentrations during the summer months of 2012, and the vertical distributions will be

    Since 2002 the Careers in Science (CiS) intern program has monitored Ocean Beach in San Francisco, California for the population of Emerita analoga (Pacific Mole Crab) as part of a partnership program with the Long-term Monitoring Program and Experiential Training for Students (LiMPETS). LiMPETS is an organization that conducts citizen science with Bay Area youth such as the CiS interns. We specifically assist in the collection of Pacific Mole Crab population statistics at Ocean Beach during the summer from June through August. The purpose of collecting Pacific Mole Crabs is to monitor Acanthocephalan parasites (Profilicollis spp.) - to which Pacific Mole Crabs serve as intermediate hosts - and to learn more about our environment as Pacific Mole Crabs are indicator species. During our collections at Ocean Beach we record size, sex, and number of individuals at specific transects. We then take a random sample from the day, return to the lab, and record their sizes, sexes, and Acanthocephalan parasite load. The results of the collection and dissections are then entered into the LiMPETS online database for scientist and researchers to use. Our project will focus on correlations relating to the data collected (Pacific Mole Crab population, parasite load, abiotic and biotic factors, et cetera).

  6. Large Earthquake Hazard of the San Jacinto Fault Zone, CA, from Long Record of Simulated Seismicity Assimilating the Available Instrumental and Paleoseismic Data

    We investigate spatio-temporal properties of earthquake patterns in the San Jacinto fault zone (SJFZ), California, between Cajon Pass and the Superstition Hill Fault, using a long record of simulated seismicity constrained by available seismological and geological data. The model provides an effective realization of a large segmented strike-slip fault zone in a 3D elastic half-space, with heterogeneous distribution of static friction chosen to represent several clear step-overs at the surface. The simulated synthetic catalog reproduces well the basic statistical features of the instrumental seismicity recorded at the SJFZ area since 1981. The model also produces events larger than those included in the short instrumental record, consistent with paleo-earthquakes documented at sites along the SJFZ for the last 1,400 years. The general agreement between the synthetic and observed data allows us to address with the long-simulated seismicity questions related to large earthquakes and expected seismic hazard. The interaction between m ≥ 7 events on different sections of the SJFZ is found to be close to random. The hazard associated with m ≥ 7 events on the SJFZ increases significantly if the long record of simulated seismicity is taken into account. The model simulations indicate that the recent increased number of observed intermediate SJFZ earthquakes is a robust statistical feature heralding the occurrence of m ≥ 7 earthquakes. The hypocenters of the m ≥ 5 events in the simulation results move progressively towards the hypocenter of the upcoming m ≥ 7 earthquake.

    Early career scientist were provided support to attend and participate in the Actinides 2009 (AN2009) International Conference held in San Francisco, California from 12-17 July 2011. This is the premier conference in the field of actinide chemistry, physics, and materials science of the actinide elements. Participation in the preeminent scientific meeting in actinide science keeps the U.S at the forefront of developments in this key field. The specific involvement of early career scientists combats the loss of expertise in the aforementioned critical areas related to f-element chemistry such as energy, homeland, and environmental security. Without these trained scientists, the U.S. will not be able to properly exploit nuclear technology to its fullest and will not be able to address its energy needs in either an environmentally safe or cost–effective manner nor will it be able to provide for its national defense. Furthermore, the early career scientists added greatly to the scientific content of the meeting and stimulates early career scientists to remain in the filed of actinide science. Providing support for participation in the AN2009 Conference via registration fee waivers, hotel cost support, and travel cost support, was extremely effective in securing the participation of early career scientists that would have not otherwise been able to attend.

    We report the results of qualitative (n=19) and quantitative (n=545) interviews with young injection drug users (IDUs) in San Diego, California, USA about their experiences using drugs in Tijuana, Mexico, and associated risks for HIV infection. Young IDUs who have ever traveled to Mexico (n=365) used a variety of injection (54%) and non-injection (30%) drugs there, and appear to be heavier users than those who have never traveled to Mexico. Sociocultural themes influencing drug use in Mexico included: interactions amongst the purpose of travel, drug preference, and route of administration; familiarity with the border region; evolving relationships with the US and Mexican drug markets; and the experience of crossing the US/Mexico border. Interventions for IDUs in border regions need to be sensitive to the ethnicity, familiarity with the border region, and life history of participants, as well as differences in national policies that could influence drug use and risk for HIV on both sides of the border.

    To investigate rainfall-runoff conditions that generate post-wildfire debris flows, we instrumented and surveyed steep, small watersheds along the tectonically active front of the San Gabriel Mountains, California. Fortuitously, we recorded runoff-generated debris-flows triggered by one spatially restricted convective event with 28 mm of rainfall falling over 62 minutes. Our rain gages, nested hillslope overland-flow sensors and soil-moisture probes, as well as a time series of terrestrial laser scanning (TLS) revealed the effects of the storm. Hillslope overland-flow response, along two ~10-m long flow lines perpendicular to and originating from a drainage divide, displayed only a 10 to 20 minute delay from the onset of rainfall with accumulated totals of merely 5-10 mm. Depth-stratified soil-moisture probes displayed a greater time delay, roughly 20- 30 minutes, indicating that initial overland flow was Hortonian. Furthermore, a downstream channel-monitoring array recorded a pronounced discharge peak generated by the passage of a debris flow after 18 minutes of rainfall. At this time, only four of the eleven hillslope overlandflow sensors confirmed the presence of surface-water flow. Repeat TLS and detailed field mapping using GPS document how patterns of rainsplash, overland-flow scour, and rilling contributed to the generation of meter-scale debris flows. In response to a single small storm, the debris flows deposited irregular levees and lobate terminal snouts on hillslopes and caused widespread erosion of the valley axis with ground surface lowering exceeding 1.5 m.
