Furthermore, forests along three major snowmelt rivers in the northern Rocky Mountains, USA, have smaller than expected areas of young trees, suggesting that high flows and channel migration have decreased since the late 1800s.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Reference module in earth systems and environmental sciences; Treatise on geomorphology, Volume 12","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Academic Press","doi":"10.1016/B978-0-12-374739-6.00319-5","usgsCitation":"Merigliano, M., Friedman, J., and Scott, M.L., 2013, Tree-ring records of variation in flow and channel geometry, chap. <i>of</i> Reference module in earth systems and environmental sciences; Treatise on geomorphology, Volume 12, v. 12, p. 145-164, https://doi.org/10.1016/B978-0-12-374739-6.00319-5.","productDescription":"20 p.","startPage":"145","endPage":"164","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-024510","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":326036,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57a315d4e4b006cb45558bb9","contributors":{"authors":[{"text":"Merigliano, M.F.","contributorId":30190,"corporation":false,"usgs":true,"family":"Merigliano","given":"M.F.","affiliations":[],"preferred":false,"id":644573,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Friedman, J.M.","contributorId":88671,"corporation":false,"usgs":true,"family":"Friedman","given":"J.M.","affiliations":[],"preferred":false,"id":644574,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Scott, M.

However, few studies have quantitatively evaluated habitat quality in these areas. Our main objective was to evaluate the habitat quality of back and main channel areas for several species using habitat suitability index (HSI) models. To test the effectiveness of these models, we attempted to relate HSI scores and the variables measured for each model with measures of relative abundance for the model species. The mean belted kingfisher (Ceryle alcyon) HSI was greater on the main than back channel. However, the model failed to predict kingfisher abundance. The mean reproduction component of the great blue heron (Ardea herodias) HSI, total common muskrat (Ondatra zibethicus) HSI, winter cover component of the snapping turtle (Chelydra serpentina) HSI, and brood-rearing component of the wood duck (Aix sponsa) HSI were all greater on the back than main channel, and were positively related with the relative abundance of each species. We found that island back channels provide characteristics not found elsewhere on the Ohio River and warrant conservation as important riparian wildlife habitat. The effectiveness of using HSI models to predict species abundance on the river was mixed. Modifications to several of the models are needed to improve their use on the Ohio River and, likely, other large rivers. </p>","language":"English","publisher":"SciRes","doi":"10.4236/oje.2013.34035","usgsCitation":"Anderson, J.T., Zadnik, A.K., Wood, P.B., and Bledsoe, K., 2013, Evaluation of habitat quality for selected wildlife species associated with back channels.: Open Journal Of Ecology, v. 3, no. 4, p. 301-310, https://doi.org/10.4236/oje.2013.34035.","productDescription":"10 p.","startPage":"301","endPage":"310","ipdsId":"IP-043835","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":474023,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.4236/oje.2013.34035","text":"Publisher Index Page"},{"id":328361,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","issue":"4","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57d28bace4b0571647d0f92e","contributors":{"authors":[{"text":"Anderson, James T.","contributorId":28071,"corporation":false,"usgs":false,"family":"Anderson","given":"James","email":"","middleInitial":"T.","affiliations":[{"id":12432,"text":"West Virginia University","active":true,"usgs":false}],"preferred":false,"id":648363,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zadnik, Andrew K.","contributorId":174476,"corporation":false,"usgs":false,"family":"Zadnik","given":"Andrew","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":648364,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wood, Petra Bohall pbwood@usgs.gov","contributorId":1791,"corporation":false,"usgs":true,"family":"Wood","given":"Petra","email":"pbwood@usgs.gov","middleInitial":"Bohall","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":false,"id":640954,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bledsoe, Kerry","contributorId":174477,"corporation":false,"usgs":false,"family":"Bledsoe","given":"Kerry","email":"","affiliations":[],"preferred":false,"id":648365,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Managing wetlands effectively requires an understanding of basic ecosystem processes, animal and plant life history strategies, and principles of wildlife management. Management techniques that are used differ depending on target species, coastal versus interior wetlands, and available infrastructure, resources, and management objectives. Ideally, wetlands are managed as a complex, with many successional stages and hydroperiods represented in close proximity. Managing wetland wildlife typically involves manipulating water levels and vegetation in the wetland, and providing an upland buffer. Commonly, levees and water control structures are used to manipulate wetland hydrology in combination with other management techniques (e.g., disking, burning, herbicide application) to create desired plant and wildlife responses. In the United States, several conservation programs are available to assist landowners in developing wetland management infrastructure on their property. Managing wetlands to increase habitat quality for wildlife is critical, considering this ecosystem is one of the most imperiled in the world.</span></p>","language":"English","publisher":"Springer Netherlands","doi":"10.1007/978-94-007-6907-6_4","usgsCitation":"Gray, M.J., Hagy, H.M., J.

They are well-known pollinators and seed dispersers, but crop pest suppression is probably the most valuable ecosystem service provided by bats. Scientific literature and popular media often include reports of crop pests in the diet of bats and anecdotal or extrapolated estimates of how many insects are eaten by bats. However, quantitative estimates of the ecosystem services provided by bats in agricultural systems are rare, and the few estimates that are available are limited to a single cotton-dominated system in Texas. Despite the tremendous value for conservation and economic security of such information, surprisingly few scientific efforts have been dedicated to quantifying the economic value of bats. Here, we outline the types of information needed to better quantify the value of bats in agricultural ecosystems. Because of the complexity of the ecosystems involved, creative experimental design and innovative new methods will help advance our knowledge in this area. Experiments involving bats in agricultural systems may be needed sooner than later, before population declines associated with white-nose syndrome and wind turbines potentially render them impossible.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Bat evolution, ecology, and conservation","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Springer","doi":"10.1007/978-1-4614-7397-8_24","isbn":"978-1-4614-7396-1","usgsCitation":"Boyles, J.G., Sole, C.L., Cryan, P.M., and McCracken, G.F., 2013, On estimating the economic value of insectivorous bats: Prospects and priorities for biologists, chap. <i>of</i> Bat evolution, ecology, and conservation, p. 501-515, https://doi.org/10.1007/978-1-4614-7397-8_24.","productDescription":"15 p.","startPage":"501","endPage":"515","ipdsId":"IP-041113","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":349367,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"UNITED STATES","noUsgsAuthors":false,"publicationDate":"2013-07-08","publicationStatus":"PW","scienceBaseUri":"5a610328e4b06e28e9c254d9","contributors":{"authors":[{"text":"Boyles, Justin G.","contributorId":26810,"corporation":false,"usgs":true,"family":"Boyles","given":"Justin","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":723575,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sole, Catherine L.","contributorId":200850,"corporation":false,"usgs":false,"family":"Sole","given":"Catherine","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":723576,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cryan, Paul M. 0000-0002-2915-8894 cryanp@usgs.gov","orcid":"https://orcid.org/0000-0002-2915-8894","contributorId":2356,"corporation":false,"usgs":true,"family":"Cryan","given":"Paul","email":"cryanp@usgs.gov","middleInitial":"M.","affiliations":[{"id":547,"text":"Rocky Mountain Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":723577,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McCracken, Gary F.","contributorId":94789,"corporation":false,"usgs":true,"family":"McCracken","given":"Gary","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":723578,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Amphiboles are rare but present in all magma compositions (low- to high-silica andesites) from the 3 month long eruption. Unzoned magnesiohornblende in the high- and low-silica andesites exhibit limited compositional variability, relatively high SiO<sub>2</sub> (up to 49·7 wt %), and relatively low Al<sub>2</sub>O<sub>3</sub> (&lt; 11·1 wt %). Intermediate-silica andesites and quenched mafic enclaves contain amphiboles that vary in composition (e.g. SiO<sub>2</sub> 40·8–48·9 wt %, Al<sub>2</sub>O<sub>3</sub> 6·52–15·2 wt %) and classification (magnesiohornblende–magnesiohastingsite–tschermakite). Compositional variation in amphibole is primarily controlled by temperature-dependent substitutions. Both high- and low-silica andesites represent remnant magmas that were stored in the shallow crust at 4–8 km depth, remaining distinct owing to a complex subsurface plumbing system. Intermediate-silica andesites and quenched mafic inclusions represent pre-eruptive hybrids of resident high- and low-silica andesite magmas and an intruding basalt. Amphiboles in explosive phase high-silica andesites are largely euhedral and unreacted, consistent with the high magma flux rates from depth during this phase (up to 13 800 m<sup>3</sup> s<sup>–1</sup>). Phenocrysts from the other lithologies have reaction rims that range from 1 to &gt;1000 μm in thickness. Reaction rim microlite sizes correlate with reaction rim thicknesses. Reaction rims &lt;50 μm thick contain microlites 1–10 μm in length whereas reaction rims &gt;80 μm thick contain microlites 10–100 μm in length. Differentiating between heating- and decompression-induced amphibole reaction rim formation is problematic because of a lack of experimental constraints. We attempt a new approach to assessing reaction rim formation, based on a kinetic theory of crystal nucleation and growth, in which the differences in reaction rim textures represent different degrees of amphibole disequilibrium. Large crystals and low number densities suggest relatively lower levels of disequilibrium resulting in growth-dominated crystallization. Smaller crystals and larger number densities are indicative of higher nucleation rates and a high driving force.</p>","language":"English","publisher":"Oxford Academic","doi":"10.1093/petrology/egt037","usgsCitation":"De Angelis, S., Larsen, J.D., and Coombs, M.L., 2013, Pre-eruptive magmatic conditions at Augustine Volcano, Alaska, 2006: Evidence from amphibole geochemistry and textures: Journal of Petrology, v. 54, no. 9, p. 1939-1961, https://doi.org/10.1093/petrology/egt037.","productDescription":"23 p.","startPage":"1939","endPage":"1961","ipdsId":"IP-049353","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":339998,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Augustine Volcano","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -153.66302490234375,\n              59.279914277804906\n            ],\n            [\n              -153.2537841796875,\n              59.279914277804906\n            ],\n            [\n              -153.2537841796875,\n              59.44228245633653\n            ],\n            [\n              -153.66302490234375,\n              59.44228245633653\n            ],\n            [\n              -153.66302490234375,\n              59.279914277804906\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"54","issue":"9","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2013-07-12","publicationStatus":"PW","scienceBaseUri":"58f877c2e4b0b7ea54521c40","contributors":{"authors":[{"text":"De Angelis, Sarah","contributorId":191167,"corporation":false,"usgs":false,"family":"De Angelis","given":"Sarah","affiliations":[],"preferred":false,"id":692057,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Larsen, Jessica D","contributorId":156309,"corporation":false,"usgs":false,"family":"Larsen","given":"Jessica","email":"","middleInitial":"D","affiliations":[{"id":6752,"text":"University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":false,"id":692058,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Coombs, Michelle L. 0000-0002-6002-6806 mcoombs@usgs.gov","orcid":"https://orcid.org/0000-0002-6002-6806","contributorId":2809,"corporation":false,"usgs":true,"family":"Coombs","given":"Michelle","email":"mcoombs@usgs.gov","middleInitial":"L.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":692056,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The conjunctive use now includes many facets of water rights, water use, and emerging demands between the states of New Mexico and Texas, the United States and Mexico, and various water-supply agencies. The analysis of the complex relations between irrigation and streamflow supplyand-demand components and the effects of surface-water and groundwater use requires an integrated hydrologic model to track all of the use and movement of water. MODFLOW with the Farm Process (MFFMP) provides the integrated approach needed to assess the stream-aquifer interactions that are dynamically affected by irrigation demands on streamflow allotments that are supplemented with groundwater pumpage. As a first step to the ongoing full implementation of MF-FMP by the USGS, the existing model (LRG_2007) was modified to include some FMP features, demonstrating the ability to simulate the existing streamflow-diversion relations known as the D2 and D3 curves, departure of downstream deliveries from these curves during low allocation years and with increasing efficiency upstream, and the dynamic relation between surface-water conveyance and estimates of pumpage and recharge. This new MF-FMP modeling framework can now internally analyze complex relations within the Lower Rio Grande Hydrologic Model (LRGHM_2011) that previous techniques had limited ability to assess.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"MODFLOW and more 2013--Translating science into practice","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"Colorado School of Mines, Integrated Groundwater Modeling Center","publisherLocation":"Golden, CO","usgsCitation":"Hanson, R.T., Schmid, W., Knight, J.E., and Maddock, T., 2013, Integrated hydrologic modeling of a transboundary aquifer system —Lower Rio Grande, <i>in</i> MODFLOW and more 2013--Translating science into practice, p. 57-61.","productDescription":"5 p.","startPage":"57","endPage":"61","ipdsId":"IP-042752","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":333539,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58833023e4b0d0023163779a","contributors":{"authors":[{"text":"Hanson, Randall T. 0000-0002-9819-7141 rthanson@usgs.gov","orcid":"https://orcid.org/0000-0002-9819-7141","contributorId":801,"corporation":false,"usgs":true,"family":"Hanson","given":"Randall","email":"rthanson@usgs.gov","middleInitial":"T.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":654190,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schmid, Wolfgang","contributorId":140408,"corporation":false,"usgs":false,"family":"Schmid","given":"Wolfgang","email":"","affiliations":[{"id":6624,"text":"University of Arizona, Laboratory of Tree-Ring Research","active":true,"usgs":false}],"preferred":false,"id":654192,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Knight, Jacob E. 0000-0003-0271-9011 jknight@usgs.gov","orcid":"https://orcid.org/0000-0003-0271-9011","contributorId":5143,"corporation":false,"usgs":true,"family":"Knight","given":"Jacob","email":"jknight@usgs.gov","middleInitial":"E.","affiliations":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true}],"preferred":true,"id":654189,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Maddock, Thomas III","contributorId":32983,"corporation":false,"usgs":true,"family":"Maddock","given":"Thomas","suffix":"III","affiliations":[],"preferred":false,"id":654191,"contributorType":{"id":1,"text":"Authors"},"rank":12}]}}

One aspect that has not changed is metadata. Static spatial data quality descriptions were standardized in the mid-1990s and cannot accommodate the current climate of data creation where nonexperts are using mobile phones and other location-based devices on a continuous basis to contribute data to Internet mapping platforms. The usability of standard geospatial metadata is being questioned by academics and neogeographers alike. This chapter analyzes current discussions of metadata to demonstrate how the media shift that is occurring has affected requirements for metadata. Two case studies of metadata use are presented&mdash;online sharing of environmental information through a regional spatial data infrastructure in the early 2000s, and new types of metadata that are being used today in OpenStreetMap, a map of the world created entirely by volunteers. Changes in metadata requirements are examined for usability, the ease with which metadata supports coproduction of data by communities of users, how metadata enhances findability, and how the relationship between metadata and data has changed. We argue that traditional metadata associated with spatial data infrastructures is inadequate and suggest several research avenues to make this type of metadata more interactive and effective in the GeoWeb.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Crowdsourcing geographic knowledge volunteered geographic information (VGI) in theory and practice","language":"English","publisher":"Springer","publisherLocation":"Dordrecht; New York","doi":"10.1007/978-94-007-4587-2_4","usgsCitation":"Poore, B.S., and Wolf, E.B., 2013, Metadata squared: enhancing its usability for volunteered geographic information and the GeoWeb, chap. <i>of</i> Crowdsourcing geographic knowledge volunteered geographic information (VGI) in theory and practice, p. 43-64, https://doi.org/10.1007/978-94-007-4587-2_4.","productDescription":"21 p.","startPage":"43","endPage":"64","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":242,"text":"Eastern Geographic Science Center","active":true,"usgs":true}],"links":[{"id":310571,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationDate":"2012-06-29","publicationStatus":"PW","scienceBaseUri":"562a08d9e4b011227bf1fd91","contributors":{"editors":[{"text":"Sui, Daniel Z.","contributorId":149381,"corporation":false,"usgs":false,"family":"Sui","given":"Daniel","email":"","middleInitial":"Z.","affiliations":[],"preferred":false,"id":578216,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Elwood, Sarah","contributorId":149382,"corporation":false,"usgs":false,"family":"Elwood","given":"Sarah","email":"","affiliations":[],"preferred":false,"id":578217,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Goodchild, Michael F.","contributorId":149383,"corporation":false,"usgs":false,"family":"Goodchild","given":"Michael","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":578218,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"Poore, Barbara S. bspoore@usgs.gov","contributorId":2541,"corporation":false,"usgs":true,"family":"Poore","given":"Barbara","email":"bspoore@usgs.gov","middleInitial":"S.","affiliations":[],"preferred":true,"id":578214,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wolf, Eric B. ebwolf@usgs.gov","contributorId":4535,"corporation":false,"usgs":true,"family":"Wolf","given":"Eric","email":"ebwolf@usgs.gov","middleInitial":"B.","affiliations":[],"preferred":true,"id":578215,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

It is the main copper mineral in several different ore deposit types, the most important of which are porphyry deposits. Chalcopyrite is unstable at the Earth's surface, so it weathers from sulphide outcrops and mine waste piles, contributing acid and dissolved copper to what is known as acid rock drainage. If not prevented, dissolved copper from chalcopyrite weathering will be transported downstream, potentially harming ecosystems along the way. Pristine areas are becoming targets for future copper supply as we strive to meet ever-increasing demands for copper by developed and developing nations. Additionally, our uses for copper are expanding to include technology such as solar energy production. This has lead to the processing of increasingly lower grade ores, which is possible, in part, due to advances in bio-leaching (i.e. metal extraction catalysed by micro-organisms). Although copper is plentiful, it is still a nonrenewable resource. Future copper supply promises to fall short of demand and the volatility of the copper market may continue if we do not prioritize copper use and improve copper recycling and ore extraction efficiency.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1365-2451.2013.00862.x","usgsCitation":"Kimball, B.E., 2013, Chalcopyrite—bearer of a precious, non-precious metal: Geology Today, v. 29, no. 1, p. 30-35, https://doi.org/10.1111/j.1365-2451.2013.00862.x.","productDescription":"6 p.","startPage":"30","endPage":"35","ipdsId":"IP-029960","costCenters":[{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":346330,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"1","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationDate":"2013-01-24","publicationStatus":"PW","scienceBaseUri":"59d3502be4b05fe04cc34d7a","contributors":{"authors":[{"text":"Kimball, Bryn E. bekimball@usgs.gov","contributorId":4184,"corporation":false,"usgs":true,"family":"Kimball","given":"Bryn","email":"bekimball@usgs.gov","middleInitial":"E.","affiliations":[],"preferred":true,"id":711681,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Owing to the socio-economical context of that region, the volcano lacks ground-based geodetic measurements but has been monitored by interferometric synthetic aperture radar (InSAR) since 1996. A combination of 3D Mixed Boundary Element Method and inverse modelling, taking into account topography and source interactions, is used to interpret InSAR ground displacements associated with eruptive activity in 1996, 2002, 2004, 2006 and 2010. These eruptions can be fitted by models incorporating dyke intrusions, and some (namely the 2006 and 2010 eruptions) require a magma reservoir beneath the summit caldera. We investigate inter-eruptive deformation with a multi-temporal InSAR approach. We propose the following magma plumbing system at Nyamulagira by integrating numerical deformation models with other available data: a deep reservoir (c. 25 km depth) feeds a shallower reservoir (c. 4 km depth); proximal eruptions are fed from the shallow reservoir through dykes while distal eruptions can be fed directly from the deep reservoir. A dyke-like conduit is also present beneath the upper southeastern flank of Nyamulagira.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Remote Sensing of Volcanoes and Volcanic Processes: Integrating Observation and Modelling","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Geological Society of London","publisherLocation":"London, UK","doi":"10.1144/SP380.9","usgsCitation":"Wauthier, C., Cayol, V., Poland, M.P., Kervyn, F., D’Oreye, N., Hooper, A., Samsonov, S., Tiampo, K., and Smets, B., 2013, Nyamulagira’s magma plumbing system inferred from 15 years of InSAR, chap. <i>of</i> Remote Sensing of Volcanoes and Volcanic Processes: Integrating Observation and Modelling, v. 380, p. 39-65, https://doi.org/10.1144/SP380.9.","productDescription":"27 p.","startPage":"39","endPage":"65","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-075418","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":474165,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://uca.hal.science/hal-03049852","text":"External Repository"},{"id":324113,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"380","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2013-06-18","publicationStatus":"PW","scienceBaseUri":"576a6545e4b07657d1a11e3d","contributors":{"editors":[{"text":"Pyle, D.

From these data, the seismic moment tensor, indicating mostly normal faulting with a small implosive component, and the radiated energy were measured; the deviatoric component of the moment tensor was estimated to be M0 = 2.3×1012 N·m and the radiated energy ER = 5.4×108 J. This event caused extensive damage along tunnels within the Pretorius fault zone. What rendered this earthquake of particular interest was the underground investigation of the complex pattern of exposed rupture surfaces combined with laboratory testing of rock samples retrieved from the ancient fault zone (Heesakkers et al.2011a, 2011b). Event 12/12 2004 was the result of fault slip across at least four nonparallel fault surfaces; 25 mm of slip was measured at one location on the rupture segment that is most parallel with a fault plane inferred from the seismic moment tensor, suggesting that this segment accounted for much of the total seismic deformation. By applying a recently developed technique based on biaxial stick-slip friction experiments (McGarr2012, 2013) to the seismic results, together with the 25 mm slip observed underground, we estimated a maximum slip rate of at least 6.6 m/s, which is consistent with the observed damage to tunnels in the rupture zone. Similarly, the stress drop and apparent stress were found to be correspondingly high at 21.9 MPa and 6.6 MPa, respectively. The ambient state of stress, measured at the approximate depth of the earthquake but away from the influence of mining, in conjunction with laboratory measurements of the strength of the fault zone cataclasites, indicates that during rupture of the M 2.2 event, the normal stress acting on the large-slip fault segment was about 260 MPa, the yield stress was 172 MPa and the seismic efficiency was 0.05. Thus, for event 12/12 2004, 5% of the energy released by the earthquake was radiated and the remaining 95% was consumed in overcoming fault friction and expanding the zone of rupture. </p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proc. 8th International Symposium on Rockbursts and Seismicity in Mines","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"Geophysical Survey and Mining Institute of the Russian Academy of Sciences","usgsCitation":"McGarr, A.F., Johnston, M.J., Boettcher, M., Heesakkers, V., and Reches, Z., 2013, Constraints on behaviour of a mining‐induced earthquake inferred from laboratory rock mechanics experiments, <i>in</i> Proc. 8th International Symposium on Rockbursts and Seismicity in Mines, p. 3-10.","productDescription":"8 p.","startPage":"3","endPage":"10","ipdsId":"IP-044866","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":350989,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5a7586dee4b00f54eb1d8215","contributors":{"authors":[{"text":"McGarr, Arthur F. 0000-0001-9769-4093 mcgarr@usgs.gov","orcid":"https://orcid.org/0000-0001-9769-4093","contributorId":3178,"corporation":false,"usgs":true,"family":"McGarr","given":"Arthur","email":"mcgarr@usgs.gov","middleInitial":"F.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":715989,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnston, Malcolm J.

The Blytheville Arch has been interpreted at various times as a compressive structure, an igneous intrusion, or a sediment diapir. Reprocessed industry seismic-reflection profiles presented here show a strong similarity between the Blytheville Arch and pop-up structures, or flower structures, within strike-slip fault systems. The Blytheville Arch formed in the Paleozoic, but post–Mid-Cretaceous to Quaternary strata show displacement or folding indicative of faulting. Faults within the graben structure but outside of the Blytheville Arch also appear to displace Upper Cretaceous and perhaps younger strata, indicating that past faulting was not restricted to the Blytheville Arch and New Madrid seismic zone. As much as 10–12.5 km of strike slip can be estimated from apparent shearing of the Reelfoot arm of the New Madrid seismic zone. There also appears to be ~5–5.5 km of shearing of the Reelfoot topographic scarp at the north end of the southern arm of the New Madrid seismic zone and of the southern portion of Crowley's Ridge, which is a north-trending topographic ridge just south of the seismic zone. These observations suggest that there has been substantial strike-slip displacement along the Blytheville Arch and southern arm of the New Madrid seismic zone, that strike-slip extended north and south of the modern seismic zone, and that post–Mid-Cretaceous (post-Eocene?) faulting was not restricted to the Blytheville Arch or to currently active faults within the New Madrid seismic zone.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/2012.2493(01)","usgsCitation":"Pratt, T.L., Williams, R., Odum, J., and Stephenson, W.J., 2013, Origin of the Blytheville Arch, and long-term displacement on the New Madrid seismic zone, central United States: GSA Special Papers, v. 493, p. 1-15, https://doi.org/10.1130/2012.2493(01).","productDescription":"15 p.","startPage":"1","endPage":"15","ipdsId":"IP-034944","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":342270,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"New Madrid seismic zone","volume":"493","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"593910b5e4b0764e6c5e88f1","contributors":{"authors":[{"text":"Pratt, Thomas L. 0000-0003-3131-3141 tpratt@usgs.gov","orcid":"https://orcid.org/0000-0003-3131-3141","contributorId":3279,"corporation":false,"usgs":true,"family":"Pratt","given":"Thomas","email":"tpratt@usgs.gov","middleInitial":"L.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true},{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":697532,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Williams, Robert 0000-0002-2973-8493 rawilliams@usgs.gov","orcid":"https://orcid.org/0000-0002-2973-8493","contributorId":140741,"corporation":false,"usgs":true,"family":"Williams","given":"Robert","email":"rawilliams@usgs.gov","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":697531,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Odum, Jackson K. 0000-0003-4697-2430 odum@usgs.gov","orcid":"https://orcid.org/0000-0003-4697-2430","contributorId":1365,"corporation":false,"usgs":true,"family":"Odum","given":"Jackson K.","email":"odum@usgs.gov","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":697530,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stephenson, William J. 0000-0001-8699-0786 wstephens@usgs.gov","orcid":"https://orcid.org/0000-0001-8699-0786","contributorId":695,"corporation":false,"usgs":true,"family":"Stephenson","given":"William","email":"wstephens@usgs.gov","middleInitial":"J.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":697533,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

In contrast to the widely held view that forest management should emphasize providing water for downstream uses, we argue that maintaining forest health in the context of a changing climate may require focusing on the forests themselves and on strategies to reduce their vulnerability to increasing water stress. Management strategies would need to be tailored to specific landscapes but could include thinning, planting and selecting for drought-tolerant species, irrigating, and making more water available to plants for transpiration. Hydrologic modeling reveals that specific management actions could reduce tree mortality due to drought stress. Adopting water conservation for vegetation as a priority for managing water on forested lands would represent a fundamental change in perspective and potentially involve trade-offs with other downstream uses of water.","language":"English","publisher":"The Ecological Society of America","doi":"10.1890/120209","usgsCitation":"Grant, G., Tague, C.L., and Allen, C.D., 2013, Watering the forest for the trees: An emerging priority for managing water in forest landscapes: Frontiers in Ecology and the Environment, v. 11, no. 6, p. 314-321, https://doi.org/10.1890/120209.","productDescription":"8 p.","startPage":"314","endPage":"321","ipdsId":"IP-043682","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":273966,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"11","issue":"6","noUsgsAuthors":false,"publicationDate":"2013-08-08","publicationStatus":"PW","scienceBaseUri":"51c18170e4b0dd0e00d92241","contributors":{"authors":[{"text":"Grant, Gordon E.","contributorId":30881,"corporation":false,"usgs":false,"family":"Grant","given":"Gordon E.","affiliations":[{"id":12647,"text":"U.S. Forest Service, Pacific Northwest Research Station","active":true,"usgs":false}],"preferred":false,"id":479864,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tague, Christina L.","contributorId":54493,"corporation":false,"usgs":true,"family":"Tague","given":"Christina","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":479865,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Allen, Craig D. 0000-0002-8777-5989 craig_allen@usgs.gov","orcid":"https://orcid.org/0000-0002-8777-5989","contributorId":2597,"corporation":false,"usgs":true,"family":"Allen","given":"Craig","email":"craig_allen@usgs.gov","middleInitial":"D.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true},{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"preferred":true,"id":479863,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Interspecies differences in both the demand for nutrients and in foliar and litter nutrient concentrations could drive variations in both the pool sizes and fluxes of important belowground resources, yet our understanding of the effects and importance of aboveground heterogeneity on belowground biogeochemistry is poor, especially in the species-rich forests of the wet tropics. To investigate the effects of individual tree species on belowground biogeochemical processes, we used both field and laboratory studies to examine how carbon (C), nitrogen (N), and phosphorus (P) cycles vary under nine different canopy tree species – including three legume and six non-legume species – that vary in foliar nutrient concentrations in a wet tropical forest in southwestern Costa Rica. We found significant differences in belowground C, N and P cycling under different canopy tree species: total C, N and P pools in standing litter varied by species, as did total soil and microbial C and N pools. Rates of soil extracellular acid phosphatase activity also varied significantly among species and functional groups, with higher rates of phosphatase activity under legumes. In addition, across all tree species, phosphatase activity was significantly positively correlated with litter N/P ratios, suggesting a tight coupling between relative N and P inputs and resource allocation to P acquisition. Overall, our results suggest the importance of aboveground plant community composition in promoting belowground biogeochemical heterogeneity at relatively small spatial scales.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Soil Biology and Biochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.soilbio.2012.10.041","usgsCitation":"Keller, A.B., Reed, S.C., Townsend, A.R., and Cleveland, C.C., 2013, Effects of canopy tree species on belowground biogeochemistry in a lowland wet tropical forest: Soil Biology and Biochemistry, v. 58, p. 61-69, https://doi.org/10.1016/j.soilbio.2012.10.041.","productDescription":"9 p.","startPage":"61","endPage":"69","ipdsId":"IP-042182","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":272138,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":272137,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.soilbio.2012.10.041"}],"otherGeospatial":"Costa Rica","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -87.0,5.5 ], [ -87.0,11.22 ], [ -82.55,11.22 ], [ -82.55,5.5 ], [ -87.0,5.5 ] ] ] } } ] }","volume":"58","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"518cc565e4b05ebc8f7cc11f","contributors":{"authors":[{"text":"Keller, Adrienne B.","contributorId":62904,"corporation":false,"usgs":true,"family":"Keller","given":"Adrienne","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":477967,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reed, Sasha C. 0000-0002-8597-8619 screed@usgs.gov","orcid":"https://orcid.org/0000-0002-8597-8619","contributorId":462,"corporation":false,"usgs":true,"family":"Reed","given":"Sasha","email":"screed@usgs.gov","middleInitial":"C.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":477964,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Townsend, Alan R.","contributorId":62868,"corporation":false,"usgs":true,"family":"Townsend","given":"Alan","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":477966,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Cleveland, Cory C.","contributorId":10264,"corporation":false,"usgs":true,"family":"Cleveland","given":"Cory","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":477965,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The low rank coal samples, from major coal fields of Pakistan, were treated with MW1 for 7&nbsp;days in the presence of 0.1% ammonium sulfate as nitrogen source and 0.1% glucose as a supplemental carbon source. Liquid extracts were analyzed through Excitation&ndash;Emission Matrix Spectroscopy (EEMS) to obtain qualitative estimates of solubilized coal; these analyses indicated the release of complex organic functionalities. In addition, GC&ndash;MS analysis of these extracts confirmed the presence of single ring aromatics, polyaromatic hydrocarbons (PAHs), aromatic nitrogen compounds and aliphatics. Subsequently, the released organics were subjected to a bioassay for the generation of methane which conferred the potential application of fungal degradation as pretreatment. Additionally, fungal-mediated degradation was also prospected for extracting some other chemical entities like humic acids from brown coals with high huminite content especially from Thar, the largest lignite reserve of Pakistan.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.fuel.2012.05.015","usgsCitation":"Haider, R., Ghauri, M.A., SanFilipo, J.R., Jones, E., Orem,

More recently, spatial interpolation techniques of point data have been shown to be effective for predicting streamflow statistics (i.e., flood flows and low-flow indices) in ungauged catchments. Literature reports successful applications of two techniques, canonical kriging, CK (or physiographical-space-based interpolation, PSBI), and topological kriging, TK (or top-kriging). CK performs the spatial interpolation of the streamflow statistic of interest in the two-dimensional space of catchment descriptors. TK predicts the streamflow statistic along river networks taking both the catchment area and nested nature of catchments into account. It is of interest to understand how these spatial interpolation methods compare with generalized least squares (GLS) regression, one of the most common approaches to estimate flood quantiles at ungauged locations. By means of a leave-one-out cross-validation procedure, the performance of CK and TK was compared to GLS regression equations developed for the prediction of 10, 50, 100 and 500 yr floods for 61 streamgauges in the southeast United States. TK substantially outperforms GLS and CK for the study area, particularly for large catchments. The performance of TK over GLS highlights an important distinction between the treatments of spatial correlation when using regression-based or spatial interpolation methods to estimate flood quantiles at ungauged locations. The analysis also shows that coupling TK with CK slightly improves the performance of TK; however, the improvement is marginal when compared to the improvement in performance over GLS.</span><span><br /></span></p>","language":"English","publisher":"Copernicus Publications","doi":"10.5194/hess-17-1575-2013","usgsCitation":"Archfield, S.A., Pugliese, A., Castellarin, A., Skoien, J.O., and Kiang, J.E., 2013, Topological and canonical kriging for design flood prediction in ungauged catchments: an improvement over a traditional regional regression approach?: Hydrology and Earth System Sciences, v. 17, p. 1575-1588, https://doi.org/10.5194/hess-17-1575-2013.","productDescription":"14 p.","startPage":"1575","endPage":"1588","numberOfPages":"14","onlineOnly":"Y","additionalOnlineFiles":"N","ipdsId":"IP-041594","costCenters":[{"id":376,"text":"Massachusetts Water Science Center","active":true,"usgs":true}],"links":[{"id":474174,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5194/hess-17-1575-2013","text":"Publisher Index Page"},{"id":297289,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -171.73828125,\n              17.97873309555617\n            ],\n            [\n              -171.73828125,\n              71.35706654962706\n            ],\n            [\n              -66.26953125,\n              71.35706654962706\n            ],\n            [\n              -66.26953125,\n              17.97873309555617\n            ],\n            [\n              -171.73828125,\n              17.97873309555617\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"17","publishingServiceCenter":{"id":11,"text":"Pembroke PSC"},"noUsgsAuthors":false,"publicationDate":"2013-04-23","publicationStatus":"PW","scienceBaseUri":"54dd2c72e4b08de9379b3803","contributors":{"authors":[{"text":"Archfield, Stacey A. 0000-0002-9011-3871 sarch@usgs.gov","orcid":"https://orcid.org/0000-0002-9011-3871","contributorId":1874,"corporation":false,"usgs":true,"family":"Archfield","given":"Stacey","email":"sarch@usgs.gov","middleInitial":"A.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true},{"id":502,"text":"Office of Surface Water","active":true,"usgs":true}],"preferred":true,"id":538597,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pugliese, Alessio","contributorId":138746,"corporation":false,"usgs":false,"family":"Pugliese","given":"Alessio","email":"","affiliations":[{"id":12516,"text":"Dept.

Whereas seismic noise interferometry allows long-range extraction of interpretable signals from a relatively weak noise wavefield, the characterization of volcanic tremor often requires a dense seismic array close to the source. We here show that standard processing of seismic noise interferometry yields volcanic tremor signals observable over large distances exceeding 50 km. Our study comprises 2.5 yr of data from the U.S. Geological Survey Hawaiian Volcano Observatory short period seismic network. Examining more than 700 station pairs, we find anomalous and temporally coherent signals that obscure the Green's functions. The time windows and frequency bands of these anomalous signals correspond well with the characteristics of previously studied volcanic tremor sources at Pu'u 'Ō'ō and Halema'uma'u craters. We use the derived noise cross-correlation functions to perform a grid-search for source location, confirming that these signals are surface waves originating from the known tremor sources. A grid-search with only distant stations verifies that useful tremor signals can indeed be recovered far from the source. Our results suggest that the specific data processing in seismic noise interferometry—typically used for Green's function retrieval—can aid in the study of both the wavefield and source location of volcanic tremor over large distances. In view of using the derived Green's functions to image heterogeneity and study temporal velocity changes at volcanic regions, however, our results illustrate how care should be taken when contamination by tremor may be present.</span></p>","language":"English","publisher":"Oxford Academic","doi":"10.1093/gji/ggt112","usgsCitation":"Ballmer, S., Wolfe, C.J., Okubo, P.G., Haney, M.M., and Thurber, C.H., 2013, Ambient seismic noise interferometry in Hawai'i reveals long-range observability of volcanic tremor: Geophysical Journal International, v. 194, no. 1, p. 512-523, https://doi.org/10.1093/gji/ggt112.","productDescription":"12 p.","startPage":"512","endPage":"523","ipdsId":"IP-045362","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":474040,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1093/gji/ggt112","text":"Publisher Index Page"},{"id":348123,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawai'i","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -156.23107910156247,\n              18.88030044453507\n            ],\n            [\n              -154.7698974609375,\n              18.88030044453507\n            ],\n            [\n              -154.7698974609375,\n              20.2982655686933\n            ],\n            [\n              -156.23107910156247,\n              20.2982655686933\n            ],\n            [\n              -156.23107910156247,\n              18.88030044453507\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"194","issue":"1","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2013-04-16","publicationStatus":"PW","scienceBaseUri":"59fc2eafe4b0531197b27ff7","contributors":{"authors":[{"text":"Ballmer, Silke","contributorId":199612,"corporation":false,"usgs":false,"family":"Ballmer","given":"Silke","email":"","affiliations":[],"preferred":false,"id":719579,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wolfe, Cecily J. 0000-0003-3144-5697 cwolfe@usgs.gov","orcid":"https://orcid.org/0000-0003-3144-5697","contributorId":191613,"corporation":false,"usgs":true,"family":"Wolfe","given":"Cecily","email":"cwolfe@usgs.gov","middleInitial":"J.","affiliations":[{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true}],"preferred":true,"id":719577,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Okubo, Paul G. 0000-0002-0381-6051 pokubo@usgs.gov","orcid":"https://orcid.org/0000-0002-0381-6051","contributorId":2730,"corporation":false,"usgs":true,"family":"Okubo","given":"Paul","email":"pokubo@usgs.gov","middleInitial":"G.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":false,"id":719576,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Haney, Matthew M. 0000-0003-3317-7884 mhaney@usgs.gov","orcid":"https://orcid.org/0000-0003-3317-7884","contributorId":172948,"corporation":false,"usgs":true,"family":"Haney","given":"Matthew","email":"mhaney@usgs.gov","middleInitial":"M.","affiliations":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":719575,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Thurber, Clifford H. 0000-0002-4940-4618","orcid":"https://orcid.org/0000-0002-4940-4618","contributorId":73184,"corporation":false,"usgs":false,"family":"Thurber","given":"Clifford","email":"","middleInitial":"H.","affiliations":[{"id":16925,"text":"University of Wisconsin-Madison","active":true,"usgs":false}],"preferred":false,"id":719578,"contributorType":{"id":1,"text":"Authors"},"rank":13}]}}

Thanks to this robust chronologic framework, much of the interpretation of the paleogeography of the region from about 18 Ma to 13 Ma is based on study of the rocks in the Mud Hills. Eastward from the type section, the Barstow Formation typically is altered and structurally complex, and therefore it is hard to fit into the patterns inferred for sedimentation at the type section. We have studied ten tuff beds in five locations, extracting zircons that are partly eruptive components of the volcanic ash and partly detrital. Ion microprobe dating of the zircons associated with the ashes allows us to improve stratigraphic correlations. Dated tuffs range from 19.3 Ma to ~14.8 Ma. In several of the sections, we dated tuffs in the range 16.2-16.5 Ma, about the same age as the ~16.3 Ma Rak Tuff in the type section. The beginning of lacustrine limestone, shale, and siltstone deposition varies significantly, from ~16.3 Ma in the type section to ~18.5 Ma in hills to the east and the Calico Mountains, and greater than 19.3 Ma at Harvard Hill. At ~16.3 Ma, the sedimentary rocks ranged (west to east) from silty sandstone and limestone, to mudstone with gypsum, to massive mudstone, and then to sandstone. If the sections have not been greatly shuffled by subsequent faulting, the picture that emerges is one of a broad basin whose center near the Yermo Hills was occupied by a lake that was much longer lived and deeper than to the east and west.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Raising Questions in the Central Mojave Desert","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"California State University Desert Studies Center 2013 Desert Symposium","language":"English","publisher":"California State University Fullerton","usgsCitation":"Miller, D., Rosario, J.E., Leslie, S.R., and Vazquez, J.A., 2013, Paleogeographic insights based on new U-Pb dates for altered tuffs in the Miocene Barstow Formation, California, <i>in</i> Raising Questions in the Central Mojave Desert, p. 31-38.","productDescription":"8 p.","startPage":"31","endPage":"38","ipdsId":"IP-044824","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":350064,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5a610312e4b06e28e9c254ac","contributors":{"authors":[{"text":"Miller, David M. 0000-0003-3711-0441 dmiller@usgs.gov","orcid":"https://orcid.org/0000-0003-3711-0441","contributorId":140769,"corporation":false,"usgs":true,"family":"Miller","given":"David M.","email":"dmiller@usgs.gov","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true},{"id":309,"text":"Geology and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":725188,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rosario, Jose E.","contributorId":201396,"corporation":false,"usgs":false,"family":"Rosario","given":"Jose","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":725190,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Leslie, Shannon R.","contributorId":148038,"corporation":false,"usgs":false,"family":"Leslie","given":"Shannon","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":725191,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vazquez, Jorge A. 0000-0003-2754-0456 jvazquez@usgs.gov","orcid":"https://orcid.org/0000-0003-2754-0456","contributorId":4458,"corporation":false,"usgs":true,"family":"Vazquez","given":"Jorge","email":"jvazquez@usgs.gov","middleInitial":"A.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":5056,"text":"Office of the AD Energy and Minerals, and Environmental Health","active":true,"usgs":true},{"id":501,"text":"Office of Science Quality and Integrity","active":true,"usgs":true}],"preferred":true,"id":725189,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
