Burn treatments were fall, early-season, growing-season, late-season, and 1 or 5 years after a prior early-season wildfire. For these treatments, we compared the number of flowering stems and of flowers for species overall, for the 20 most prolifically flowering species, as well as for species grouped by flowering phenoperiods, and by growth form. Growing-season burn had a significant negative effect on number of flowering stems and total number of flowers. This effect occurred when either the burn occurred during the flowering season or during the season prior to the flowering phenoperiod. <i>Tradescantia ohiensis</i> showed expedited flowering and <i>Phlox pilosa</i> showed delayed flowering in response to early-season burning. Flowering of early shrubs was reduced by the previous fall and early-spring fires, while flowering of mid-season blooming shrubs was reduced by the early- and growing-season burns. <i>Vaccinium</i> and <i>Gaylussacia</i>, early-flowering shrubs, produced fewer flowers 1 year after than 5 years after an early-season burn. Arabis lyrata showed reduced flowering from the early-season burn. We also found four instances where the early-spring burn effect on flowering was more severe than the fall burn effect, suggesting that many frequent early-season burns may be deleterious to flowering and reproduction of some species. Burns occurring too frequently in the same season could negatively affect future flowering and reproduction of these plant species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Plant Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s11258-010-9851-5","issn":"13850237","usgsCitation":"Pavlovic, N., Leicht-Young, S.A., and Grundel, R., 2011, Short-term effects of burn season on flowering phenology of savanna plants: Plant Ecology, v. 212, no. 4, p. 611-625, https://doi.org/10.1007/s11258-010-9851-5.","productDescription":"15 p.","startPage":"611","endPage":"625","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":243608,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215783,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s11258-010-9851-5"}],"volume":"212","issue":"4","noUsgsAuthors":false,"publicationDate":"2010-10-27","publicationStatus":"PW","scienceBaseUri":"505b8eb8e4b08c986b318ada","contributors":{"authors":[{"text":"Pavlovic, N.B.","contributorId":105076,"corporation":false,"usgs":true,"family":"Pavlovic","given":"N.B.","email":"","affiliations":[],"preferred":false,"id":447114,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Leicht-Young, S.

The Albemarle Embayment, a Cenozoic regional depositional basin in eastern North Carolina located on the southeast Atlantic coast of the USA, is an ideal setting to unravel these dynamic, interrelated processes.</p><p id=\"sp0105\">Micropaleontological data, coupled with sedimentologic, chronostratigraphic and seismic data provide the bases for detailed interpretations of paleoenvironmental evolution and paleoclimates in the 90&nbsp;m thick Quaternary record of the Albemarle Embayment. The data presented here come from a transect of cores drilled through a barrier island complex in the central Albemarle Embayment.

Barrier island and marginal marine deposits have a low preservation potential. Inner to mid-shelf deposits of the early Pleistocene are overlain by similar middle Pleistocene shelf sediments in the south of the study area but entirely by inner shelf deposits in the north. Late Pleistocene marine sediments are of inner shelf origin and Holocene deposits are marginal marine in nature. Pleistocene marine sediments are incised, particularly in the northern half of the embayment by lowstand paleovalleys, partly filled by fluvial/floodplain deposits and in some cases, overlain by remnants of transgressive estuarine sediments. The shallowing through time of Quaternary sediments reflects the eastward progradational geometry of the continental shelf.</p><p id=\"sp0115\">The preservation potential of marginal marine deposits (barrier island, shoreface, backbarrier deposits) is not high, except in topographic lows associated with late Pleistocene paleovalleys and inlets because the current interglacial highstand has not yet reached its highest level. Given the documented increase in rate of relative sea-level rise in this region, shallow marine conditions are likely to return to the central Albemarle Embayment in the near future.</p>","language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.palaeo.2011.03.004","issn":"00310182","usgsCitation":"Culver, S., Farrell, K.M., Mallinson, D., Willard, D.A., Horton, B.P., Riggs, S., Thieler, E.R., Wehmiller, J.F., Parham, P., Snyder, S.W., and Hillier, C., 2011, Micropaleontologic record of Quaternary paleoenvironments in the Central Albemarle Embayment, North Carolina, U.S.A.: Palaeogeography, Palaeoclimatology, Palaeoecology, v. 305, no. 1-4, p. 227-249, https://doi.org/10.1016/j.palaeo.2011.03.004.","productDescription":"23 p.","startPage":"227","endPage":"249","additionalOnlineFiles":"N","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"links":[{"id":243809,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215972,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.palaeo.2011.03.004"}],"country":"United States","state":"North Carolina","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -84.462890625,\n              35.02999636902566\n            ],\n            [\n              -82.96875,\n              35.10193405724606\n            ],\n            [\n              -81.5625,\n              35.17380831799959\n            ],\n            [\n              -80.947265625,\n              35.10193405724606\n            ],\n            [\n              -79.89257812499999,\n              34.95799531086792\n            ],\n            [\n              -78.31054687499999,\n              33.578014746143985\n            ],\n            [\n              -75.05859375,\n              36.10237644873644\n            ],\n            [\n              -76.025390625,\n              36.59788913307022\n            ],\n            [\n              -81.650390625,\n              36.4566360115962\n            ],\n            [\n              -82.96875,\n              35.88905007936091\n            ],\n            [\n              -84.19921875,\n              35.53222622770337\n            ],\n            [\n              -84.462890625,\n              35.02999636902566\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"305","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a568de4b0c8380cd6d684","contributors":{"authors":[{"text":"Culver, Stephen J.","contributorId":79331,"corporation":false,"usgs":true,"family":"Culver","given":"Stephen J.","affiliations":[],"preferred":false,"id":448607,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Farrell, Kathleen M.","contributorId":64476,"corporation":false,"usgs":true,"family":"Farrell","given":"Kathleen","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":448605,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mallinson, David J.","contributorId":74222,"corporation":false,"usgs":true,"family":"Mallinson","given":"David J.","affiliations":[],"preferred":false,"id":448606,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Willard, Debra A. 0000-0003-4878-0942 dwillard@usgs.gov","orcid":"https://orcid.org/0000-0003-4878-0942","contributorId":2076,"corporation":false,"usgs":true,"family":"Willard","given":"Debra","email":"dwillard@usgs.gov","middleInitial":"A.","affiliations":[{"id":411,"text":"National Climate Change and Wildlife Science Center","active":true,"usgs":true},{"id":24693,"text":"Climate Research and Development","active":true,"usgs":true}],"preferred":true,"id":448599,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Horton, Benjamin P.","contributorId":63641,"corporation":false,"usgs":true,"family":"Horton","given":"Benjamin","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":448604,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Riggs, Stanley R.","contributorId":25983,"corporation":false,"usgs":true,"family":"Riggs","given":"Stanley R.","affiliations":[],"preferred":false,"id":448601,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Thieler, E.

A contaminated and an uncontaminated core were retrieved from a site contaminated with crude oil near Bemidji, Minnesota and subsampled for MS measurements. The contaminated core revealed enriched MS zones within the hydrocarbon smear zone, which is related to iron-reduction coupled to oxidation of hydrocarbon compounds and the vadose zone, which is coincident with a zone of methane depletion suggesting aerobic or anaerobic oxidation of methane is coupled to iron-reduction. The latter has significant implications for methane cycling.

The monitoring techniques consist of permanent sensors and tools deployed for measurement campaigns. Large amounts of data are thus generated. These data must be managed and integrated for interpretation at different time scales. A fast interpretation loop involves combining continuous measurements from permanent sensors as they are collected to enable a rapid response to detected events; a slower loop requires combining large datasets gathered over longer operational periods from all techniques. The purpose of this paper is twofold. First, it presents an analysis of the monitoring objectives to be performed in the slow and fast interpretation loops. Second, it describes the implementation of the fast interpretation loop with a real-time monitoring system at the Illinois Basin–Decatur Project (IBDP) in Illinois, USA.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.egypro.2011.02.548","issn":"18766102","usgsCitation":"Picard, G., Berard, T., Chabora, E., Marsteller, S., Greenberg, S., Finley, R., Rinck, U., Greenaway, R., Champagnon, C., and Davard, J., 2011, Real-time monitoring of CO2 storage sites: Application to Illinois Basin-Decatur Project: Energy Procedia, v. 4, p. 5594-5598, https://doi.org/10.1016/j.egypro.2011.02.548.","productDescription":"5 p.","startPage":"5594","endPage":"5598","numberOfPages":"5","costCenters":[],"links":[{"id":487837,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.egypro.2011.02.548","text":"Publisher Index Page"},{"id":243486,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a95a8e4b0c8380cd81b64","contributors":{"authors":[{"text":"Picard, G.","contributorId":28094,"corporation":false,"usgs":true,"family":"Picard","given":"G.","email":"","affiliations":[],"preferred":false,"id":447449,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Berard, T.","contributorId":74588,"corporation":false,"usgs":true,"family":"Berard","given":"T.","email":"","affiliations":[],"preferred":false,"id":447454,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chabora, E.","contributorId":73841,"corporation":false,"usgs":true,"family":"Chabora","given":"E.","email":"","affiliations":[],"preferred":false,"id":447453,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Marsteller, S.","contributorId":27288,"corporation":false,"usgs":true,"family":"Marsteller","given":"S.","email":"","affiliations":[],"preferred":false,"id":447448,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Greenberg, S.","contributorId":79925,"corporation":false,"usgs":true,"family":"Greenberg","given":"S.","email":"","affiliations":[],"preferred":false,"id":447456,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Finley, R.J.","contributorId":70984,"corporation":false,"usgs":true,"family":"Finley","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":447452,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Rinck, U.","contributorId":87389,"corporation":false,"usgs":true,"family":"Rinck","given":"U.","email":"","affiliations":[],"preferred":false,"id":447457,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Greenaway, R.","contributorId":77383,"corporation":false,"usgs":true,"family":"Greenaway","given":"R.","email":"","affiliations":[],"preferred":false,"id":447455,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Champagnon, C.","contributorId":66087,"corporation":false,"usgs":true,"family":"Champagnon","given":"C.","email":"","affiliations":[],"preferred":false,"id":447450,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Davard, J.","contributorId":66508,"corporation":false,"usgs":true,"family":"Davard","given":"J.","email":"","affiliations":[],"preferred":false,"id":447451,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

We determined relative abundances of grassland birds in oak barrens and dry sand prairies&mdash;native habitat types rare in the state of Wisconsin. We also investigated the association of relative abundance, patch size, and patch vegetation. Our study was conducted May&ndash;July 2000&ndash;2002 on Fort McCoy Military Installation in Monroe County, Wisconsin. Fourteen grassland bird species were found in native habitat patches. Vesper sparrow (</span><i>Pooecetes gramineus</i><span>), grasshopper sparrow (</span><i>Ammodramus savannarum</i><span>), and field sparrow (</span><i>Spizella pusilla</i><span>) were the most abundant grassland bird species; all are species of management concern in Wisconsin. Of the most abundant species, only grasshopper sparrow relative abundance increased as patch size increased; vesper sparrow and field sparrow relative abundances decreased as patch size increased. Though found at lower relative abundances, horned larks (</span><i>Erephila alpestris</i><span>), savannah sparrows (</span><i>Passerculus sandwichensis</i><span>), and upland sandpipers (</span><i>Bartramia longicauda</i><span>) were found at higher relative abundances as patch size increased. Patch vegetation was important for some species. Vesper sparrows were found at higher abundances in patches with shorter, less dense vegetation and higher woody cover, eastern meadowlark (</span><i>Sturnella magna</i><span>) relative abundances were higher in patches with higher proportions of grass, and dickcissel (</span><i>Spiza americana</i><span>) relative abundances were higher in patches with taller, denser vegetation and lower proportions of litter. Native habitats are important for grassland bird species of management concern and large patches are particularly important for some of them.</span></p>","language":"English","publisher":"Natural

In both species, the annual birth season was delayed by dry conditions and El Niño years, and delayed birth seasons were linked to lower birth rates. Additionally, increased mean annual temperatures were associated with lower birth rates for northern muriquis. Offspring sex ratios varied with climatic conditions in both species, but in different ways: directly in woolly monkeys and indirectly in northern muriquis. Woolly monkeys displayed an increase in the proportion of males among offspring in association with El Niño events, whereas in northern muriquis, increases in the proportion of males among offspring were associated with delayed onset of the birth season, which itself was related, although weakly, to warm, dry conditions. These results illustrate that global warming, increased drought frequency, and changes in the frequency of El Niño events could limit primate reproductive output, threatening the persistence and recovery of ateline primate populations.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1365-2486.2011.02427.x","issn":"13541013","usgsCitation":"Wiederholt, R., and Post, E., 2011, Birth seasonality and offspring production in threatened neotropical primates related to climate: Global Change Biology, v. 17, no. 10, p. 3035-3045, https://doi.org/10.1111/j.1365-2486.2011.02427.x.","productDescription":"11 p.","startPage":"3035","endPage":"3045","costCenters":[],"links":[{"id":243509,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215688,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2486.2011.02427.x"}],"volume":"17","issue":"10","noUsgsAuthors":false,"publicationDate":"2011-04-20","publicationStatus":"PW","scienceBaseUri":"5059f1cfe4b0c8380cd4ae31","contributors":{"authors":[{"text":"Wiederholt, R.","contributorId":34350,"corporation":false,"usgs":true,"family":"Wiederholt","given":"R.","email":"","affiliations":[],"preferred":false,"id":446441,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Post, E.","contributorId":25736,"corporation":false,"usgs":false,"family":"Post","given":"E.","email":"","affiliations":[{"id":6738,"text":"The Pennsylvania State University","active":true,"usgs":false}],"preferred":false,"id":446440,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This study examines up to 20 years of publicly available, continuous temperature and salinity data from 10 different San Francisco Bay stations to identify trends in temperature and salinity and quantify the salinityfreshwater inflow relationship. Several trends in the salinity and temperature records were identified, although the high degree of daily and interannual variability confounds the analysis. In addition, freshwater inflow to the estuary has a range of effects on salinity from -0.0020 to -0.0096 (m3 s-1) -1 discharge, depending on location in the estuary and the timescale of analyzed data. Finally, we documented that changes in freshwater inflow to the estuary that are within the range of typical management actions can affect bay-wide salinities by 0.61.4.

The goal of CM3 is to address emerging issues in climate change, including aerosol–cloud interactions, chemistry–climate interactions, and coupling between the troposphere and stratosphere. The model is also designed to serve as the physical system component of earth system models and models for decadal prediction in the near-term future—for example, through improved simulations in tropical land precipitation relative to earlier-generation GFDL models. This paper describes the dynamical core, physical parameterizations, and basic simulation characteristics of the atmospheric component (AM3) of this model. Relative to GFDL AM2, AM3 includes new treatments of deep and shallow cumulus convection, cloud droplet activation by aerosols, subgrid variability of stratiform vertical velocities for droplet activation, and atmospheric chemistry driven by emissions with advective, convective, and turbulent transport. AM3 employs a cubed-sphere implementation of a finite-volume dynamical core and is coupled to LM3, a new land model with ecosystem dynamics and hydrology. Its horizontal resolution is approximately 200 km, and its vertical resolution ranges approximately from 70 m near the earth’s surface to 1 to 1.5 km near the tropopause and 3 to 4 km in much of the stratosphere. Most basic circulation features in AM3 are simulated as realistically, or more so, as in AM2. In particular, dry biases have been reduced over South America. In coupled mode, the simulation of Arctic sea ice concentration has improved. AM3 aerosol optical depths, scattering properties, and surface clear-sky downward shortwave radiation are more realistic than in AM2. The simulation of marine stratocumulus decks remains problematic, as in AM2. The most intense 0.2% of precipitation rates occur less frequently in AM3 than observed. The last two decades of the twentieth century warm in CM3 by 0.32°C relative to 1881–1920. The Climate Research Unit (CRU) and Goddard Institute for Space Studies analyses of observations show warming of 0.56° and 0.52°C, respectively, over this period. CM3 includes anthropogenic cooling by aerosol–cloud interactions, and its warming by the late twentieth century is somewhat less realistic than in CM2.1, which warmed 0.66°C but did not include aerosol–cloud interactions. The improved simulation of the direct aerosol effect (apparent in surface clear-sky downward radiation) in CM3 evidently acts in concert with its simulation of cloud–aerosol interactions to limit greenhouse gas warming.</span></p>","language":"English","publisher":"American Meteorological Society","doi":"10.1175/2011JCLI3955.1","issn":"08948755","usgsCitation":"Donner, L., Wyman, B., Hemler,

We assessed streamflow alteration at 2888 streamflow monitoring sites throughout the conterminous US. The magnitudes of mean annual (1980–2007) minimum and maximum streamflows were found to have been altered in 86% of assessed streams. The occurrence, type, and severity of streamflow alteration differed markedly between arid and wet climates. Biological assessments conducted on a subset of these streams showed that, relative to eight chemical and physical covariates, diminished flow magnitudes were the primary predictors of biological integrity for fish and macroinvertebrate communities. In addition, the likelihood of biological impairment doubled with increasing severity of diminished streamflows. Among streams with diminished flow magnitudes, increasingly common fish and macroinvertebrate taxa possessed traits characteristic of lake or pond habitats, including a preference for fine‐grained substrates and slow‐moving currents, as well as the ability to temporarily leave the aquatic environment.</span></p>","language":"English","publisher":"Ecological Society of America","doi":"10.1890/100053","issn":"15409295","usgsCitation":"Carlisle, D.M., Wolock, D.M., and Meador, M., 2011, Alteration of streamflow magnitudes and potential ecological consequences: A multiregional assessment: Frontiers in Ecology and the Environment, v. 9, no. 5, p. 264-270, https://doi.org/10.1890/100053.","productDescription":"7 p.","startPage":"264","endPage":"270","costCenters":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"links":[{"id":475370,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://zenodo.org/record/1236389","text":"External Repository"},{"id":243667,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215838,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/100053"}],"volume":"9","issue":"5","noUsgsAuthors":false,"publicationDate":"2010-10-25","publicationStatus":"PW","scienceBaseUri":"5059e978e4b0c8380cd482db","contributors":{"authors":[{"text":"Carlisle, Daren M. 0000-0002-7367-348X dcarlisle@usgs.gov","orcid":"https://orcid.org/0000-0002-7367-348X","contributorId":513,"corporation":false,"usgs":true,"family":"Carlisle","given":"Daren","email":"dcarlisle@usgs.gov","middleInitial":"M.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true},{"id":503,"text":"Office of Water Quality","active":true,"usgs":true},{"id":27111,"text":"National Water Quality Program","active":true,"usgs":true},{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true}],"preferred":true,"id":447129,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wolock, David M. 0000-0002-6209-938X dwolock@usgs.gov","orcid":"https://orcid.org/0000-0002-6209-938X","contributorId":540,"corporation":false,"usgs":true,"family":"Wolock","given":"David","email":"dwolock@usgs.gov","middleInitial":"M.","affiliations":[{"id":503,"text":"Office of Water Quality","active":true,"usgs":true},{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true},{"id":27111,"text":"National Water Quality Program","active":true,"usgs":true},{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true},{"id":37778,"text":"WMA - Integrated Modeling and Prediction Division","active":true,"usgs":true}],"preferred":true,"id":447127,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Meador, Michael R. mrmeador@usgs.gov","contributorId":615,"corporation":false,"usgs":true,"family":"Meador","given":"Michael R.","email":"mrmeador@usgs.gov","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":true,"id":447128,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We pooled stream chemistry and total suspended sediment (TSS) data sets from three discrete periods: 1983–1987, 1991–1997, and 2000–2008. During this period three major hurricanes crossed the site: Hugo in 1989, Hortense in 1996, and Georges in 1998. Stream chemistry reflects sea salt inputs (Na, Cl, and SO</span><sub>4</sub><span>), and high weathering rates of the granodiorite (Ca, Mg, Si, and alkalinity). During rainfall, stream composition shifts toward that of precipitation, diluting 90% or more in the largest storms, but maintains a biogeochemical watershed signal marked by elevated K and dissolved organic carbon (DOC) concentration. DOC exhibits an unusual “boomerang” pattern, initially increasing with flow but then decreasing at the highest flows as it becomes depleted and/or vigorous overland flow minimizes contact with watershed surfaces. TSS increased markedly with discharge (power function slope 1.54), reflecting the erosive power of large storms in a landslide‐prone landscape. The relations of TSS and most solute concentrations with stream discharge were stable through time, suggesting minimal long‐term effects from repeated hurricane disturbance. Nitrate concentration, however, increased about threefold in response to hurricanes then returned to baseline over several years following a pseudo first‐order decay pattern. The combined data sets provide insight about important hydrologic pathways, a long‐term perspective to assess response to hurricanes, and a framework to evaluate future climate change in tropical ecosystems.</span></p>","largerWorkTitle":"Water Resources Research","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2010WR009788","issn":"00431397","usgsCitation":"Shanley, J.B., McDowell, W.H., and Stallard, R.F., 2011, Long-term patterns and short-term dynamics of stream solutes and suspended sediment in a rapidly weathering tropical watershed: Water Resources Research, v. 47, no. 7, W07515, 11 p., https://doi.org/10.1029/2010WR009788.","productDescription":"W07515, 11 p.","costCenters":[],"links":[{"id":246302,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218303,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2010WR009788"}],"country":"United States","state":"Puerto Rico","otherGeospatial":"Río Icacos watershed","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -65.88775634765625,\n              18.21761162872689\n            ],\n            [\n              -65.6982421875,\n              18.21761162872689\n            ],\n            [\n              -65.6982421875,\n              18.35582895074145\n            ],\n            [\n              -65.88775634765625,\n              18.35582895074145\n            ],\n            [\n              -65.88775634765625,\n              18.21761162872689\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"47","issue":"7","noUsgsAuthors":false,"publicationDate":"2011-07-09","publicationStatus":"PW","scienceBaseUri":"505a499fe4b0c8380cd68772","contributors":{"authors":[{"text":"Shanley, James B. 0000-0002-4234-3437 jshanley@usgs.gov","orcid":"https://orcid.org/0000-0002-4234-3437","contributorId":1953,"corporation":false,"usgs":true,"family":"Shanley","given":"James","email":"jshanley@usgs.gov","middleInitial":"B.","affiliations":[{"id":405,"text":"NH/VT office of New England Water Science Center","active":true,"usgs":true},{"id":466,"text":"New England Water Science Center","active":true,"usgs":true}],"preferred":true,"id":454524,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McDowell, W.

Although the species is not listed as threatened by state or federal agencies, its viability is nonetheless threatened on multiple fronts. We discuss management actions that could reduce extinction risk, including vaccination, captive propagation, biosecurity measures, and establishing a second free-living population on a neighboring island. Establishing a second population on Santa Rosa Island may have the added benefit of accelerating the restoration and enhancing the resilience of that island's currently highly degraded ecosystem. The proactive management framework for island scrub-jays presented here illustrates how strategies for species protection, ecosystem restoration, and adaptation to and mitigation of climate change can converge into an integrated solution.</span></p>","language":"English","publisher":"Oxford Academic","doi":"10.1525/bio.2011.61.12.11","issn":"00063568","usgsCitation":"Morrison, S., Sillett, T., Ghalambor, C.K., Fitzpatrick, J., Graber, D., Bakker, V., Bowman, R., Collins, C., Collins, P., Delaney, K., Doak, D., Koenig, W.D., Laughrin, L., Lieberman, A., Marzluff, J., Reynolds, M., Scott, J.M., Stallcup, J., Vickers, W., and Boyce, W., 2011, Proactive conservation management of an island-endemic bird species in the face of global change: BioScience, v. 61, no. 12, p. 1013-1021, https://doi.org/10.1525/bio.2011.61.12.11.","productDescription":"9 p.","startPage":"1013","endPage":"1021","costCenters":[],"links":[{"id":475117,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1525/bio.2011.61.12.11","text":"Publisher Index Page"},{"id":242979,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215196,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1525/bio.2011.61.12.11"}],"country":"United States","state":"California","otherGeospatial":"The California Channel Island","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -120.41015624999999,\n              32.63937487360669\n            ],\n            [\n              -117.2900390625,\n              32.63937487360669\n            ],\n            [\n              -117.2900390625,\n              34.252676117101515\n            ],\n            [\n              -120.41015624999999,\n              34.252676117101515\n            ],\n            [\n              -120.41015624999999,\n              32.63937487360669\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"61","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8c78e4b0c8380cd7e6e8","contributors":{"authors":[{"text":"Morrison, S.A.","contributorId":7930,"corporation":false,"usgs":true,"family":"Morrison","given":"S.A.","email":"","affiliations":[],"preferred":false,"id":450894,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sillett, T.

The district encompasses ~500 km<sup>2</sup><span>&nbsp;</span>although the distribution of all deposits has been laterally condensed by late Mesozoic crustal contraction. Zinc, Pb, and Cu production from about 90 deposits was ~160,000 metric tons (t) (Zn &gt; Pb &gt;&gt; Cu), 2.1 million ounces (Moz) Ag, 0.09 Moz Au, and small amounts of PGEs—Co, V, Hg, Sb, Ni, Mo, Mn, Ir, and U—were also recovered.</p><p id=\"p-2\">Zinc-dominant carbonate replacement deposits (Zn &gt; Pb; Ag ± Cu) resemble Mississippi Valley Type (MVT) Zn-Pb deposits in that they occur in karst and fault breccias in Mississippian limestone where the southern margin of the regional late Paleozoic foreland basin adjoins Proterozoic crystalline rocks of the craton. They consist of calcite, dolomite, sphalerite, and galena with variably positive S isotope compositions (<i>δ</i><sup>34</sup>S values range from 2.5–13‰), and highly radiogenic Pb isotope compositions (<sup>206</sup>Pb/<sup>204</sup>Pb &gt;19), typical of MVT deposits above crystalline Precambrian basement. These deposits may have formed when southward flow of saline fluids, derived from basinal and older sedimentary rocks, encountered thinner strata and pinch-outs against the craton, forcing fluid mixing and mineral precipitation in karst and fault breccias. Lead-dominant carbonate replacement deposits (Pb &gt; Zn, Ag ± Cu ± Au) occur among other deposit types, often near porphyritic intrusions. They generally contain higher concentrations of precious metals than zinc-dominant deposits and relatively abundant iron oxides after pyrite. They share characteristics with copper ± precious metal-PGE and gold ± silver deposits including fine-grained quartz replacement of carbonate minerals in ore breccias and relatively low S and Pb isotope values (<i>δ</i><sup>34</sup>S values vary from 0–~4‰;<span>&nbsp;</span><sup>206</sup>Pb/<sup>204</sup>Pb &lt;18.5). Copper ± precious metal-PGE deposits (Cu, Co, Ag, Au, Pd, and Pt) consist of Cu carbonate minerals (after chalcocite and chalcopyrite) and fine-grained quartz that have replaced breccia clasts and margins of fissures in Paleozoic limestones and dolomites near porphyritic intrusions. Gold ± silver deposits occur along contacts and within small-volume stocks and dikes of feldspar porphyry, one textural variety of porphyritic intrusions. Lead isotope compositions of copper ± precious metal-PGE, gold ± silver, and lead-dominant carbonate replacement deposits are similar to those of Mojave crust plutons, indicating derivation of Pb from 1.7 Ga crystalline basement or from Late Proterozoic siliciclastic sedimentary rocks derived from 1.7 Ga crystalline basement.</p><p id=\"p-3\">Four texturally and modally distinctive porphyritic intrusions are exposed largely in the central part of the district: feldspar quartz porphyry, plagioclase quartz porphyry, feldspar biotite quartz porphyry, and feldspar porphyry. Intrusions consist of 64 to 70 percent SiO<sub>2</sub><span>&nbsp;</span>and variable K<sub>2</sub>O/Na<sub>2</sub>O (0.14–5.33) that reflect proportions of K-feldspar and albite phenocrysts and megacrysts as well as partial alteration to K-mica; quartz and biotite phenocrysts are present in several subtypes. Albite may have formed during emplacement of magma in brine-saturated basinal strata, whereas hydrothermal alteration of matrix, phenocrystic, and megacrystic feldspar and biotite to K-mica, pyrite, and other hydrothermal minerals occurred during and after intrusion emplacement. Small volumes of garnet-diopside-quartz and retrograde epidote-mica-amphibole skarn have replaced carbonate rocks adjacent to one intrusion subtype (feldspar-quartz porphyry), but alteration of carbonate rocks at intrusion contacts elsewhere is inconspicuous.</p><p id=\"p-4\">Uranium-lead ages of igneous zircons vary inconsistently from ~ 180 to 230 Ma and are too imprecise to distinguish age differences among intrusion subtypes; most ages are 210 to 225 Ma, yielding a mean of 217 ± 1 Ma. K-Ar and<span>&nbsp;</span><sup>40</sup>Ar/<sup>39</sup>Ar ages of magmatic (plagioclase, biotite) and hydrothermal (K-mica) minerals span a similar range (183–227 Ma), demonstrating broadly contemporaneous intrusion emplacement and hydrothermal alteration but allowing for multiple Late Triassic magmatic-hydrothermal events. Imprecision and range of isotopic ages may have resulted from burial beneath Mesozoic and Tertiary strata and multiple intrusion of magmas, causing thermal disturbance to Ar systems and Pb loss from zircons in intrusions.</p><p id=\"p-5\">Separate late Paleozoic (zinc-dominant carbonate replacement deposits) and Late Triassic (all other deposits) mineralizing events are supported by form, distribution, and host rocks of metal deposits, by hydrothermal mineral assemblages, isotope compositions, metal abundances, and metal diversity, and by small intrusion volumes.

New isotopic data from the ∼98 Ma to 54 Ma Idaho batholith and ∼51 Ma to 43 Ma Challis intrusions, coupled with recent geochronological work, provide insights into the evolution of magmatism in the Idaho segment of the Cordillera. Nd and Hf isotopes show clear shifts towards more evolved compositions through the batholith's history and Pb isotopes define distinct fields correlative with the different age and compositionally defined suites of the batholith, whereas the Sr isotopic compositions of the various suites largely overlap. The subsequent Challis magmatism shows the full range of isotopic compositions seen in the batholith. These data suggest that the early suites of metaluminous magmatism (98–87 Ma) represent crust–mantle hybrids. Subsequent voluminous Atlanta peraluminous suite magmatism (83–67 Ma) results primarily from melting of different crustal components. This can be attributed to crustal thickening, resulting from either subduction processes or an outboard terrane collision. A later, smaller crustal melting episode, in the northern Idaho batholith, resulted in the Bitterroot peraluminous suite (66–54 Ma) and tapped different crustal sources. Subsequent Challis magmatism was derived from both crust and mantle sources and corresponds to extensional collapse of the over-thickened crust.</span></p>","language":"English","publisher":"Oxford Academic","doi":"10.1093/petrology/egr050","issn":"00223530","usgsCitation":"Gaschnig, R.M., Vervoort, J., Lewis, R.S., and Tikoff, B., 2011, Isotopic evolution of the idaho batholith and Challis intrusive province, Northern US Cordillera: Journal of Petrology, v. 52, no. 12, p. 2397-2429, https://doi.org/10.1093/petrology/egr050.","productDescription":"33 p.","startPage":"2397","endPage":"2429","costCenters":[],"links":[{"id":242980,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215197,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1093/petrology/egr050"}],"country":"United States","otherGeospatial":"Idaho batholith","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -119.091796875,\n              34.379712580462204\n            ],\n            [\n              -114.2578125,\n              37.23032838760387\n            ],\n            [\n              -113.818359375,\n              41.376808565702355\n            ],\n            [\n              -113.203125,\n              46.07323062540835\n            ],\n            [\n              -113.37890625,\n              49.210420445650286\n            ],\n            [\n              -122.87109375,\n              49.38237278700955\n            ],\n            [\n              -125.33203125,\n              48.3416461723746\n            ],\n            [\n              -126.12304687500001,\n              43.13306116240612\n            ],\n            [\n              -121.025390625,\n              33.43144133557529\n            ],\n            [\n              -119.091796875,\n              34.379712580462204\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"52","issue":"12","noUsgsAuthors":false,"publicationDate":"2011-11-25","publicationStatus":"PW","scienceBaseUri":"505a3fb5e4b0c8380cd6474e","contributors":{"authors":[{"text":"Gaschnig, Richard M.","contributorId":31220,"corporation":false,"usgs":true,"family":"Gaschnig","given":"Richard","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":450915,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Vervoort, J.D.","contributorId":98126,"corporation":false,"usgs":true,"family":"Vervoort","given":"J.D.","affiliations":[],"preferred":false,"id":450917,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lewis, R.

Determination of the molecular-level speciation of Hg in soils and mine wastes is important for understanding its sequestration, mobility, and availability for methylation. Extended X-ray absorption fine structure (EXAFS) spectroscopy carried out under ambient P-T conditions has been used in a number of past studies to determine Hg speciation in complex mine wastes and associated soils. However, this approach cannot detect elemental (liquid) mercury in Hg-polluted soils and sediments due to the significant structural disorder of liquid Hg at ambient-temperature. A new sample preparation protocol involving slow cooling through the crystallization temperature of Hg(0) (234 K) results in its transformation to crystalline α-Hg(0). The presence and proportion of Hg(0), relative to other crystalline Hg-bearing phases, in samples prepared in this way can be quantified by low-temperature (77 K) EXAFS spectroscopy. Using this approach, we have determined the relative concentrations of liquid Hg(0) in Hg mine wastes from several sites in the California Coast Range and have found that they correlate well with measured fluxes of gaseous Hg released during light and dark exposure of the same samples, with higher evasion ratios from samples containing higher concentrations of liquid Hg(0). Two different linear relationships are observed in plots of the ratio of Hg emission under light and dark conditions vs % Hg(0), corresponding to silica−carbonate- and hot springs-type Hg deposits, with the hot springs-type samples exhibiting higher evasion fluxes than silica−carbonate type samples at similar Hg(0) concentrations. Our findings help explain significant differences in Hg evasion data for different mine sites in the California Coast Range.</span></p>","language":"English","publisher":"American Chemical Society","doi":"10.1021/es1023527","issn":"0013936X","usgsCitation":"Jew, A., Kim, C., Rytuba, J.J., Gustin, M., and Brown, G.E., 2011, New technique for quantification of elemental hg in mine wastes and its implications for mercury evasion into the atmosphere: Environmental Science & Technology, v. 45, no. 2, p. 412-417, https://doi.org/10.1021/es1023527.","productDescription":"6 p.","startPage":"412","endPage":"417","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":475110,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://europepmc.org/articles/pmc3030447","text":"External Repository"},{"id":244140,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"45","issue":"2","noUsgsAuthors":false,"publicationDate":"2010-12-01","publicationStatus":"PW","scienceBaseUri":"505a661ae4b0c8380cd72d10","contributors":{"authors":[{"text":"Jew, A.D.","contributorId":66090,"corporation":false,"usgs":true,"family":"Jew","given":"A.D.","email":"","affiliations":[],"preferred":false,"id":451984,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kim, C.S.","contributorId":54365,"corporation":false,"usgs":true,"family":"Kim","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":451983,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rytuba, James J. jrytuba@usgs.gov","contributorId":3043,"corporation":false,"usgs":true,"family":"Rytuba","given":"James","email":"jrytuba@usgs.gov","middleInitial":"J.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":451985,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gustin, M.S.","contributorId":101837,"corporation":false,"usgs":true,"family":"Gustin","given":"M.S.","email":"","affiliations":[],"preferred":false,"id":451986,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Brown, Gordon E.

Most spawning was estimated to occur in the Piedmont physiographic region within a 25-river-kilometer (rkm) section just below the lowermost dam in the system; however, some spawning also occurred downstream in the Coastal Plain. The Piedmont region has a higher gradient and is predicted to have slightly higher current velocities and shallower depths, on average, than the Coastal Plain. The Piedmont region is dominated by large substrates (e.g., boulders and gravel), whereas the Coastal Plain is dominated by sand. Sampling at night (the primary spawning period) resulted in the collection of young eggs (&le;1.5 h old) that more precisely identified the spawning sites. In the Piedmont region, most radio-tagged American shad remained in discrete areas (average linear range = 3.6 rkm) during the spawning season and generally occupied water velocities between 0.20 and 0.69 m/s, depths between 1.0 and 2.9 m, and substrates dominated by boulder or bedrock and gravel. Tagged adults made only small-scale movements with changes in water discharge rates. Our results demonstrate that the upstream extent of migration and an area of concentrated spawning occur just below the lowermost dam.

Accelerated rates of dust emission from wind erosion have large implications for ecosystems and human well-being, yet there is poor understanding of the sources and magnitude of dust emission in a hotter and drier climate. Here we use a two-stage approach to compare the susceptibility of grasslands and three different shrublands to wind erosion on the Colorado Plateau and demonstrate how climate can indirectly moderate the magnitude of aeolian sediment flux through different responses of dominant plants in these communities. First, using results from 20&nbsp;y of vegetation monitoring, we found perennial grass cover in grasslands declined with increasing mean annual temperature in the previous year, whereas shrub cover in shrublands either showed no change or declined as temperature increased, depending on the species. Second, we used these vegetation monitoring results and measurements of soil stability as inputs into a field-validated wind erosion model and found that declines in perennial vegetation cover coupled with disturbance to biological soil crust resulted in an exponential increase in modeled aeolian sediment flux. Thus the effects of increased temperature on perennial plant cover and the correlation of declining plant cover with increased aeolian flux strongly suggest that sustained drought conditions across the southwest will accelerate the likelihood of dust production in the future on disturbed soil surfaces.</span></p>","language":"English","publisher":"National Academy of Sciences","publisherLocation":"Washington, D.C.","doi":"10.1073/pnas.1014947108","usgsCitation":"Munson, S.M., Belnap, J., and Okin, G.S., 2011, Responses of wind erosion to climate-induced vegetation changes on the Colorado Plateau: Proceedings of the National Academy of Sciences, v. 108, no. 10, p. 3854-3859, https://doi.org/10.1073/pnas.1014947108.","productDescription":"6 p.","startPage":"3854","endPage":"3859","numberOfPages":"6","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":475208,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1073/pnas.1014947108","text":"External Repository"},{"id":259593,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Utah","otherGeospatial":"Colorado Plateau","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -111.1541748046875,\n              37.09900294387622\n            ],\n            [\n              -109.22607421875,\n              37.09900294387622\n            ],\n            [\n              -109.22607421875,\n              38.94659331893374\n            ],\n            [\n              -111.1541748046875,\n              38.94659331893374\n            ],\n            [\n              -111.1541748046875,\n              37.09900294387622\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"108","issue":"10","noUsgsAuthors":false,"publicationDate":"2011-02-22","publicationStatus":"PW","scienceBaseUri":"505aaab2e4b0c8380cd864a1","contributors":{"authors":[{"text":"Munson, Seth M. 0000-0002-2736-6374 smunson@usgs.gov","orcid":"https://orcid.org/0000-0002-2736-6374","contributorId":1334,"corporation":false,"usgs":true,"family":"Munson","given":"Seth","email":"smunson@usgs.gov","middleInitial":"M.","affiliations":[{"id":411,"text":"National Climate Change and Wildlife Science Center","active":true,"usgs":true},{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":466460,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Belnap, Jayne 0000-0001-7471-2279 jayne_belnap@usgs.gov","orcid":"https://orcid.org/0000-0001-7471-2279","contributorId":1332,"corporation":false,"usgs":true,"family":"Belnap","given":"Jayne","email":"jayne_belnap@usgs.gov","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":466459,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Okin, Gregory S.","contributorId":50025,"corporation":false,"usgs":true,"family":"Okin","given":"Gregory","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":466461,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Image classification was performed using a decision-tree classification approach. We also prepared land-cover change pairs for 1983, 1984, and every 2&nbsp;y from 1984 to 2010 depicting “ecosystem shifts” (e.g., expansion, retraction, and disappearance). This new spatiotemporal information could be used to assess short-term and long-term impacts of the oil spill on mangroves. Finally, we propose an operational methodology based on remote sensing (Landsat, Advanced Spaceborne Thermal Emission and Reflection Radiometer [ASTER], hyperspectral, light detection and ranging [LIDAR], aerial photographs, and field inventory data) to monitor the existing and emerging mangrove areas and their disturbance and regrowth patterns. Several parameters such as spatial distribution, ecosystem shifts, species composition, and tree height/biomass could be measured to assess the impact of the oil spill and mangrove recovery and restoration. Future research priorities will be to quantify the impacts and recovery of mangroves considering multiple stressors and perturbations, including oil spill, winter freeze, sea-level rise, land subsidence, and land-use/land-cover change for the entire Gulf Coast.</span></p>","language":"English","publisher":"Coastal Education and Research Foundation","doi":"10.2112/JCOASTRES-D-11-00028.1","issn":"07490208","usgsCitation":"Giri, S., Long, J., and Tieszen, L., 2011, Mapping and monitoring Louisiana's mangroves in the aftermath of the 2010 Gulf of Mexico Oil spill: Journal of Coastal Research, v. 27, no. 6, p. 1059-1064, https://doi.org/10.2112/JCOASTRES-D-11-00028.1.","productDescription":"6 p.","startPage":"1059","endPage":"1064","numberOfPages":"6","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":241341,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213689,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2112/JCOASTRES-D-11-00028.1"}],"volume":"27","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5050e4b0c8380cd6b5d2","contributors":{"authors":[{"text":"Giri, S.","contributorId":102621,"corporation":false,"usgs":true,"family":"Giri","given":"S.","email":"","affiliations":[],"preferred":false,"id":436223,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Long, J.","contributorId":41993,"corporation":false,"usgs":true,"family":"Long","given":"J.","affiliations":[],"preferred":false,"id":436222,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Tieszen, L.","contributorId":22887,"corporation":false,"usgs":true,"family":"Tieszen","given":"L.","email":"","affiliations":[],"preferred":false,"id":436221,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The recoverable quantities must be described and categorized in a manner that is consistent with scientific and social/economic information describing the economy as well as with the information describing the projects to recover them. A number of different standards have evolved over time in response to various professional needs Under a mandate given by the United Nations Economic and Social Council, the United Nations Economic Commission for Europe (UNECE) has cooperated with Governments, regulatory agencies, industry, international organizations, and professional organizations (including Committee for Mineral Reserves International Reporting Standards (CRIRSCO), the Society of Petroleum Engineers (SPE), the American Association of Petroleum Geologists (AAPG), and the Society of Petroleum Evaluation Engineers (SPEE)), as well as with outstanding experts, to define a global classification for extractive activities (including oil, gas, heavy oil and bitumen extraction) that reflects the principal concerns of existing petroleum and mineral classifications. The United Nations Framework Classification for Fossil Energy and Mineral Reserves and Resources-2009 (UNFC-2009) aims to serve the following four principal needs: 1. The needs in international energy and mineral studies to formulate robust and long-sighted policies. 2. The needs of governments in managing their resources accordingly, allowing market prices to be transferred to the wellhead with as little loss as possible. 3. The industries' needs for information while deploying technology, management and finance to secure energy supplies and capture value efficiently within the established frameworks to serve its host countries, shareholders and stakeholders. 4. The financial community's need for information to allocate capital appropriately, providing reduced costs and improved long-sightedness through the application of lower risk-compensated discount factors. The projects are categorised with respect to economic and social viability, project feasibility and maturity and uncertainty with respect to the quantities addressed. The categorisation of projects rather than of accumulations provides coherence with other critical management information such as production, cash flows, value and demand for various input factors. This key aspect of UNFC-2009 reflects the critical relationship between the quantities that can be recovered economically and the recovery processes (projects) that must be implemented to achieve those recoveries. It facilitates the recognition of potential wastage of resources through flaring or inefficient recovery processes and therefore also the potential for improvement.

DYFI-based intensity maps made rapidly available through the DYFI system fundamentally depart from more traditional maps made available in the past. The maps are made more quickly, provide more complete coverage and higher resolution, provide for citizen input and interaction, and allow data collection at rates and quantities never before considered. These aspects of Internet data collection, in turn, allow for data analyses, graphics, and ways to communicate with the public, opportunities not possible with traditional data-collection approaches. Yet web-based contributions also pose considerable challenges, as discussed herein. After a decade of operational experience with the DYFI system and users, we document refinements to the processing and algorithmic procedures since DYFI was first conceived. We also describe a number of automatic post-processing tools, operations, applications, and research directions, all of which utilize the extensive DYFI intensity datasets now gathered in near-real time.
