Concentrations of PBOC and HAA were measured using aquifer sediment samples collected at six selected study sites. Average concentrations of total HAA and PBOC ranged from 1.96 ± 1.53 to 20.1 ± 25.6 mg/kg and 4.72 ± 0.72 to 443 ± 65.4 mg/kg, respectively. Results demonstrated a statistically significant positive relationship between concentrations of PBOC and total HAA present in the aquifer sediment (p < 0.05). Higher levels of HAA were consistently observed at sites with greater levels of PBOC and first-order decay rates. Because amino acids are known to be readily biodegradable carbon compounds, this relationship suggests that the sequential chemical extraction procedure used to measure PBOC is a useful indicator of bioavailable carbon in aquifer sediments. This, in turn, is consistent with the interpretation that PBOC measurements can be used for estimating the amount of natural organic carbon available for driving the reductive dechlorination of chloroethenes in groundwater systems.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ground Water Monitoring and Remediation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6592.2012.01406.x","usgsCitation":"Thomas, L.K., Widdowson, M.A., Novak, J.T., Chapelle, F.H., Benner, R., and Kaiser, K., 2012, Potentially bioavailable natural organic carbon and hydrolyzable amino acids in aquifer sediments: Ground Water Monitoring and Remediation, v. 32, no. 4, p. 92-95, https://doi.org/10.1111/j.1745-6592.2012.01406.x.","productDescription":"4 p.","startPage":"92","endPage":"95","costCenters":[],"links":[{"id":291159,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291158,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6592.2012.01406.x"}],"volume":"32","issue":"4","noUsgsAuthors":false,"publicationDate":"2012-06-27","publicationStatus":"PW","scienceBaseUri":"57f7f3c1e4b0bc0bec0a0b7f","contributors":{"authors":[{"text":"Thomas, Lashun K.","contributorId":58507,"corporation":false,"usgs":true,"family":"Thomas","given":"Lashun","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":496725,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Widdowson, Mark A.","contributorId":90379,"corporation":false,"usgs":true,"family":"Widdowson","given":"Mark","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":496727,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Novak, John T.","contributorId":41753,"corporation":false,"usgs":true,"family":"Novak","given":"John","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":496723,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Chapelle, Francis H. chapelle@usgs.gov","contributorId":1350,"corporation":false,"usgs":true,"family":"Chapelle","given":"Francis","email":"chapelle@usgs.gov","middleInitial":"H.","affiliations":[{"id":559,"text":"South Carolina Water Science Center","active":true,"usgs":true},{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"preferred":true,"id":496722,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Benner, Ronald","contributorId":57380,"corporation":false,"usgs":true,"family":"Benner","given":"Ronald","affiliations":[],"preferred":false,"id":496724,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Kaiser, Karl","contributorId":80520,"corporation":false,"usgs":true,"family":"Kaiser","given":"Karl","email":"","affiliations":[],"preferred":false,"id":496726,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

It has fascinated chemists, material scientists, archaeologists and art historians for decades because it is resistant to the effect of acids, alkalis, and other reagents, and its rich color has persisted for centuries in the harsh tropical climate of southern Mesoamerica. One of its components, palygorskite, is part of modern Maya indigenous knowledge, and ethnohistoric and archaeological data suggest that its modern sources were probably utilized in Prehispanic times. Yet no direct evidence verifies that palygorskite was actually mined from these sources to make Maya Blue. Here we characterize these sources compositionally, and compare our analyses to those of Maya Blue from Chichén Itzá and Palenque. We demonstrate that the palygorskite in most of these samples came from modern mines, providing the first direct evidence for the use of these sources for making Maya Blue. These findings reveal that modern Maya indigenous knowledge about palygorskite, its mining, and its source locations, is at least seven centuries old.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Archaeological Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.jas.2012.02.036","usgsCitation":"Arnold, D., Bohor, B., Neff, H., Feinman, G.M., Williams, P.R., Dussubieux, L., and Bishop, R., 2012, The first direct evidence of pre-columbian sources of palygorskite for Maya Blue: Journal of Archaeological Science, v. 39, no. 7, p. 2252-2260, https://doi.org/10.1016/j.jas.2012.02.036.","productDescription":"9 p.","startPage":"2252","endPage":"2260","costCenters":[],"links":[{"id":291121,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291120,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jas.2012.02.036"}],"volume":"39","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57f7f3c1e4b0bc0bec0a0b89","contributors":{"authors":[{"text":"Arnold, Dean E.","contributorId":73117,"corporation":false,"usgs":true,"family":"Arnold","given":"Dean E.","affiliations":[],"preferred":false,"id":496641,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bohor, Bruce F.","contributorId":104823,"corporation":false,"usgs":true,"family":"Bohor","given":"Bruce F.","affiliations":[],"preferred":false,"id":496643,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Neff, Hector","contributorId":102400,"corporation":false,"usgs":true,"family":"Neff","given":"Hector","email":"","affiliations":[],"preferred":false,"id":496642,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Feinman, Gary M.","contributorId":11959,"corporation":false,"usgs":true,"family":"Feinman","given":"Gary","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":496637,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Williams, Patrick Ryan","contributorId":14746,"corporation":false,"usgs":true,"family":"Williams","given":"Patrick","email":"","middleInitial":"Ryan","affiliations":[],"preferred":false,"id":496638,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Dussubieux, Laure","contributorId":58577,"corporation":false,"usgs":true,"family":"Dussubieux","given":"Laure","email":"","affiliations":[],"preferred":false,"id":496639,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Bishop, Ronald","contributorId":67809,"corporation":false,"usgs":true,"family":"Bishop","given":"Ronald","email":"","affiliations":[],"preferred":false,"id":496640,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

We used weighted networks to analyze the resource use by sea otters, testing three alternative models for how individual diet specialisation may arise. As expected, individual specialisation was absent when otter density was low, but increased at high-otter density. A high-density emergence of nested resource-use networks was consistent with the model assuming individuals share preference ranks. However, a density-dependent emergence of a non-nested modular network for &lsquo;core&rsquo; resources was more consistent with the &lsquo;competitive refuge&rsquo; model. Individuals from different diet modules showed predictable variation in rank-order prey preferences and handling times of core resources, further supporting the competitive refuge model. Our findings support a hierarchical organisation of diet specialisation and suggest individual use of core and marginal resources may be driven by different selective pressures.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology Letters","largerWorkSubtype":{"id":10,"text":"Journal

Although many independent groups have confirmed the impact evidence, the hypothesis remains controversial because some groups have failed to do so. We examined sediment sequences from 18 dated Younger Dryas boundary (YDB) sites across three continents (North America, Europe, and Asia), spanning 12,000 km around nearly one-third of the planet. All sites display abundant microspherules in the YDB with none or few above and below. In addition, three sites (Abu Hureyra, Syria; Melrose, Pennsylvania; and Blackville, South Carolina) display vesicular, high-temperature, siliceous scoria-like objects, or SLOs, that match the spherules geochemically. We compared YDB objects with melt products from a known cosmic impact (Meteor Crater, Arizona) and from the 1945 Trinity nuclear airburst in Socorro, New Mexico, and found that all of these high-energy events produced material that is geochemically and morphologically comparable, including: (i) high-temperature, rapidly quenched microspherules and SLOs; (ii) corundum, mullite, and suessite (Fe<sup>3,/sup>Si), a rare meteoritic mineral that forms under high temperatures; (iii) melted SiO<sup>2</sup> glass, or lechatelierite, with flow textures (or schlieren) that form at > 2,200 °C; and (iv) particles with features indicative of high-energy interparticle collisions. These results are inconsistent with anthropogenic, volcanic, authigenic, and cosmic materials, yet consistent with cosmic ejecta, supporting the hypothesis of extraterrestrial airbursts/impacts 12,900 years ago. The wide geographic distribution of SLOs is consistent with multiple impactors.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the National Academy of Sciences of the United States of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"National Academy of Sciences","publisherLocation":"Washington, D.C.","doi":"10.1073/pnas.1204453109","usgsCitation":"Bunch, T.E., Hermes, R.E., Moore, A., Kennett, D.J., Weaver, J., Wittke, J.H., DeCarli, P.S., Bischoff, J.L., Hillman, G.C., Howard, G.A., Kimbel, D.R., Kletetschka, G., Lipo, C.P., Sakai, S., Revay, Z., West, A., Firestone, R., and Kennett, J.P., 2012, Very high-temperature impact melt products as evidence for cosmic airbursts and impacts 12,900 years ago: Proceedings of the National Academy of Sciences of the United States of America, v. 109, no. 28, p.

However, major strike-slip faults showing NW-SE trending provide geomorphologic and paleoseismic evidence of recent tectonic activity (Late Pleistocene to Present). Moreover, these faults are consistently well oriented under the present stress tensor and therefore, they can trigger earthquakes of magnitude greater than M6, according to the lengths of surface ruptures and active segments recognized in fieldwork. Present landscape nearby the village of Hellin (SE of Albacete) is determined by the recent activity of the Pozohondo Fault (FPH), a NW-SE right-lateral fault with 90 km in length. In this study, we have calculated the Late Quaternary tectonic sliprate of the FPH from geomorphological, sedimentological, archaeoseimological, and paleoseismological approaches. All of these data suggest that the FPH runs with a minimum slip-rate of 0.1 mm/yr during the last 100 kyrs (Upper Pleistocene-Holocene). In addition, we have recognized the last two major paleoearthquakes associated to this fault. Magnitudes of these paleoearthquakes were gretarer than M6 and their recurrence intervals ranged from 6600 to 8600 yrs for the seismic cycle of FPH. The last earthquake was dated between the 1st and 6th centuries, though two earthquakes could be interpreted in this wide time interval, one at the FPH and other from a far field source.

It is an important Holocene archaeological site that was inspected in the 1970s but from which little has been published. New excavations starting in 2008 have exposed a deep Late Pleistocene stratigraphical sequence. In this paper, we present for the first time palaeoenvironmental and palaeoclimatic reconstructions of this Late Pleistocene succession on the basis of both the small-vertebrate assemblages and the charcoals. Results from the small-vertebrate associations along the sequence indicate that the landscape had open-woodland habitats in the vicinity of the Cova del Xaragalls, with wet points in the surrounding area. Woodland habitats were dominant throughout the sequence, as evidenced by the abundance of the species <i>Apodemus sylvaticus</i>, but were better developed during warm periods (layers C5 and C8), whereas during cold periods (layers C4 and C3) the environment was slightly more humid in response to higher mean annual precipitation and the opening of the landscape. The charcoal analysis indicates that the woodland surrounding the cave was composed mainly of <i>Pinus</i> (more than 90% was identified as <i>Pinus</i>), but that during the cold period (C3–C4) it incorporated some <i>Quercus ilex/coccifera</i> and Angiosperm indet., probably linked with greater precipitation. Comparisons are made with other long palaeoenvironmental sequences from the northeastern Iberian Peninsula and with global marine isotopic curves, providing a scenario for the palaeoclimatic and palaeoenvironmental changes that occurred during the Late Pleistocene in the woodland areas surrounding the Cova dels Xaragalls.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Boreas","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Boreas Collegium","doi":"10.1111/j.1502-3885.2011.00234.x","usgsCitation":"Lopez-Garcia, J.M., Blain, H., Bennasar, M., Euba, I., Banuls, S., Bischoff, J., Lopez-Ortega, E., Saladie, P., Uzquiano, P., and Vallverdu, J., 2012, A multiproxy reconstruction of the palaeoenvironment and palaeoclimate of the Late Pleistocene in northeastern Iberia: Cova dels Xaragalls, Vimbodí-Poblet, Paratge Natural de Poblet, Catalonia: Boreas, v. 41, no. 2, p. 235-249, https://doi.org/10.1111/j.1502-3885.2011.00234.x.","productDescription":"15 p.","startPage":"235","endPage":"249","costCenters":[],"links":[{"id":291022,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291021,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1502-3885.2011.00234.x"}],"country":"Spain","city":"Catalonia","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 0.1592,40.523 ], [ 0.1592,42.8615 ], [ 3.3325,42.8615 ], [ 3.3325,40.523 ], [ 0.1592,40.523 ] ] ] } } ] }","volume":"41","issue":"2","noUsgsAuthors":false,"publicationDate":"2011-11-18","publicationStatus":"PW","scienceBaseUri":"57f7f3c2e4b0bc0bec0a0b93","contributors":{"authors":[{"text":"Lopez-Garcia, Juan Manuel","contributorId":91035,"corporation":false,"usgs":true,"family":"Lopez-Garcia","given":"Juan","email":"","middleInitial":"Manuel","affiliations":[],"preferred":false,"id":496270,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blain, Hugues-Alexandre","contributorId":83037,"corporation":false,"usgs":true,"family":"Blain","given":"Hugues-Alexandre","email":"","affiliations":[],"preferred":false,"id":496269,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bennasar, Maria","contributorId":50457,"corporation":false,"usgs":true,"family":"Bennasar","given":"Maria","email":"","affiliations":[],"preferred":false,"id":496266,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Euba, Itxaso","contributorId":70303,"corporation":false,"usgs":true,"family":"Euba","given":"Itxaso","email":"","affiliations":[],"preferred":false,"id":496267,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Banuls, Sandra","contributorId":22261,"corporation":false,"usgs":true,"family":"Banuls","given":"Sandra","email":"","affiliations":[],"preferred":false,"id":496263,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bischoff, James","contributorId":22902,"corporation":false,"usgs":true,"family":"Bischoff","given":"James","affiliations":[],"preferred":false,"id":496264,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Lopez-Ortega, Esther","contributorId":11131,"corporation":false,"usgs":true,"family":"Lopez-Ortega","given":"Esther","email":"","affiliations":[],"preferred":false,"id":496262,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Saladie, Palmira","contributorId":108416,"corporation":false,"usgs":true,"family":"Saladie","given":"Palmira","email":"","affiliations":[],"preferred":false,"id":496271,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Uzquiano, Paloma","contributorId":73516,"corporation":false,"usgs":true,"family":"Uzquiano","given":"Paloma","email":"","affiliations":[],"preferred":false,"id":496268,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Vallverdu, Josep","contributorId":28177,"corporation":false,"usgs":true,"family":"Vallverdu","given":"Josep","email":"","affiliations":[],"preferred":false,"id":496265,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

These proxies were found in a 27-m-long core as part of an interdisciplinary effort to extract a paleoclimate record back through the previous interglacial. Our attention focused early on an anomalous, 10-cm-thick, carbon-rich layer at a depth of 2.8&nbsp;m that dates to 12.9&nbsp;ka and coincides with a suite of anomalous coeval environmental and biotic changes independently recognized in other regional lake sequences. Collectively, these changes have produced the most distinctive boundary layer in the late Quaternary record. This layer contains a diverse, abundant assemblage of impact-related markers, including nanodiamonds, carbon spherules, and magnetic spherules with rapid melting/quenching textures, all reaching synchronous peaks immediately beneath a layer containing the largest peak of charcoal in the core. Analyses by multiple methods demonstrate the presence of three allotropes of nanodiamond: n-diamond, i-carbon, and hexagonal nanodiamond (lonsdaleite), in order of estimated relative abundance. This nanodiamond-rich layer is consistent with the Younger Dryas boundary layer found at numerous sites across North America, Greenland, and Western Europe. We have examined multiple hypotheses to account for these observations and find the evidence cannot be explained by any known terrestrial mechanism. It is, however, consistent with the Younger Dryas boundary impact hypothesis postulating a major extraterrestrial impact involving multiple airburst(s) and and/or ground impact(s) at 12.9&nbsp;ka.</span></p>","language":"English","publisher":"National Academy of Sciences","publisherLocation":"Washington, D.C.","doi":"10.1073/pnas.1110614109","usgsCitation":"Israde-Alcántara, I., Bischoff, J.L., Dominguez-Vazquez, G., Li, H., DeCarli, P.S., Bunch, T.E., Wittke, J.H., Weaver, J., Firestone, R., West, A., Kennett, J.P., Mercer, C., Xie, S., Richman, E.K., Kinzie, C.R., and Wolbach, W.S., 2012, Evidence from central Mexico supporting the Younger Dryas extraterrestrial impact hypothesis: Proceedings of the National Academy of Sciences of the United States of America, v. 109, no. 13, p.

This symposium, built on two previous decadal scientific meetings, focused on forging scientific consensus where possible, while also articulating continued controversies regarding the Cenozoic evolution of the Colorado River System and the landscapes of the Colorado Plateau–Rocky Mountain region that it drains. New developments involved hypotheses that Neogene mantle flow is driving plateau tilting and differential uplift, with consensus that multidisciplinary studies involving differential incision studies and additional geochronology and thermochronology are needed to test the relative importance of tectonic and geomorphic forcings in shaping the spectacular landscapes of the Colorado Plateau region. In addition to the scientific goals, the meeting participants emphasized the iconic status of Grand Canyon for geosciences, and the importance of good communication between the research community, the geoscience education/interpretation community, the public, and the media. Building on a century-long tradition, this region still provides a globally important natural laboratory for studies of the interactions of erosion and tectonism in the shaping landscape of elevated plateaus.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geosphere","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Geological Society of America","publisherLocation":"Boulder, CO","doi":"10.1130/GES00716.1","usgsCitation":"Karlstrom, K.E., Beard, L.S., House, K., Young, R.A., Aslan, A., Billingsley, G., and Pederson, J., 2012, Introduction: CRevolution 2: origin and evolution of the Colorado River System II: Geosphere, v. 8, no. 6, p. 1170-1176, https://doi.org/10.1130/GES00716.1.","productDescription":"7 p.","startPage":"1170","endPage":"1176","costCenters":[],"links":[{"id":291017,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291016,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/GES00716.1"}],"country":"United States","state":"Arizona;Colorado;New Mexico;Utah","otherGeospatial":"Colorado River System","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.03,33.66 ], [ -114.03,40.87 ], [ -105.91,40.87 ], [ -105.91,33.66 ], [ -114.03,33.66 ] ] ] } } ] }","volume":"8","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-11-16","publicationStatus":"PW","scienceBaseUri":"57f7f3c2e4b0bc0bec0a0b97","contributors":{"authors":[{"text":"Karlstrom, Karl E.","contributorId":75597,"corporation":false,"usgs":true,"family":"Karlstrom","given":"Karl","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":496231,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Beard, L.

Mineral contaminants often contain much higher concentrations of metals than vegetal materials and can alter a cob’s apparent metal and heavy-isotope content. Cleaning a cob via immersion in an acid solution for more than a few minutes will result in the incongruent and sometimes complete leaching of metals, including strontium (Sr), from the cob. When using <sup>87</sup>Sr/<sup.86</sup>Sr to determine the location of potential agriculture fields, it is best to either integrate several depth-integrated soil samples or to integrate several vegetation samples from individual fields. Biologically labile Sr in semi-arid Southwestern soils largely originates from eolian source or sources and usually is not derived from underlying bedrock. Existing Sr-isotope data indicate that archaeological cobs from Aztec Ruins came from either the Mesa Verde-McElmo Dome or Totah areas, that Pueblo Bonito and Chetro Ketl cobs, from Chaco Canyon that predate A.D. 1130, probably came from the Rio Chaco corridor, and that cobs from Chaco Canyon, that postdate A.D. 1130, probably came from either the Totah or Zuni areas.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Archaeological Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.jas.2011.08.022","usgsCitation":"Benson, L.V., 2012, Development and application of methods used to source prehistoric Southwestern maize: a review: Journal of Archaeological Science, v. 39, no. 4, p. 791-807, https://doi.org/10.1016/j.jas.2011.08.022.","productDescription":"17 p.","startPage":"791","endPage":"807","costCenters":[],"links":[{"id":291014,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291013,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jas.2011.08.022"}],"volume":"39","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57f7f3c2e4b0bc0bec0a0b99","contributors":{"authors":[{"text":"Benson, Larry V. lbenson@usgs.gov","contributorId":1655,"corporation":false,"usgs":true,"family":"Benson","given":"Larry","email":"lbenson@usgs.gov","middleInitial":"V.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":496224,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

StreamStats for North Carolina, available at http://water.usgs.gov/osw/streamstats/north_carolina.html, is a Web-based Geographic Information System (GIS) application developed by the U.S. Geological Survey (USGS) in consultation with Environmental Systems Research Institute, Inc. (Esri) to provide access to an assortment of analytical tools that are useful for water-resources planning and management (Ries and others, 2008). The StreamStats application provides an accurate and consistent process that allows users to easily obtain streamflow statistics, basin characteristics, and descriptive information for USGS data-collection sites and user-selected ungaged sites. In the North Carolina application, users can compute 47 basin characteristics and peak-flow frequency statistics (Weaver and others, 2009; Robbins and Pope, 1996) for a delineated drainage basin. Selected streamflow statistics and basin characteristics for data-collection sites have been compiled from published reports and also are immediately accessible by querying individual sites from the web interface. Examples of basin characteristics that can be computed in StreamStats include drainage area, stream slope, mean annual precipitation, and percentage of forested area (Ries and others, 2008). Examples of streamflow statistics that were previously available only through published documents include peak-flow frequency, flow-duration, and precipitation data. These data are valuable for making decisions related to bridge design, floodplain delineation, water-supply permitting, and sustainable stream quality and ecology. The StreamStats application also allows users to identify stream reaches upstream and downstream from user-selected sites and obtain information for locations along streams where activities occur that may affect streamflow conditions. This functionality can be accessed through a map-based interface with the user’s Web browser, or individual functions can be requested remotely through Web services (Ries and others, 2008).","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/fs20123137","usgsCitation":"Weaver, J., Terziotti, S., Kolb, K.R., and Wagner, C.,

The low-amplitude dynamic characteristics are considerably different than those computed from design analyses, but serve as a baseline against which to compare with future strong shaking responses.

Its theoretical sensitivity limit in this range is 10(-9) m/s in ground velocity and 10(-9) rad/s in rotation rate. Small size and weight, and easy installation and maintenance make the instrument useful for local-earthquake recording and seismic prospecting.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Review of Scientific Instruments","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Institute of Physics","doi":"10.1063/1.4747713","usgsCitation":"Brokesova, J., Malek, J., and Evans, J.R., 2012, Note: Rotaphone, a new self-calibrated six-degree-of-freedom seismic sensor: Review of Scientific Instruments, v. 83, no. 8, 086108; 3 p., https://doi.org/10.1063/1.4747713.","productDescription":"086108; 3 p.","ipdsId":"IP-036515","costCenters":[{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true}],"links":[{"id":275185,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":275072,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1063/1.4747713"}],"volume":"83","issue":"8","noUsgsAuthors":false,"publicationDate":"2012-08-23","publicationStatus":"PW","scienceBaseUri":"51ea8704e4b03397884d399b","contributors":{"authors":[{"text":"Brokesova, Johana","contributorId":101967,"corporation":false,"usgs":true,"family":"Brokesova","given":"Johana","email":"","affiliations":[],"preferred":false,"id":480972,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Malek, Jiri","contributorId":40876,"corporation":false,"usgs":true,"family":"Malek","given":"Jiri","email":"","affiliations":[],"preferred":false,"id":480971,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Evans, John R. jrevans@usgs.gov","contributorId":529,"corporation":false,"usgs":true,"family":"Evans","given":"John","email":"jrevans@usgs.gov","middleInitial":"R.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":480970,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Following its initial release along the Colorado River near Moab, Utah in 2004, the beetle has successfully established and defoliated tamarisk across much of the upper Colorado River Basin. However, the spatial distribution and seasonal timing of defoliation are complex and difficult to quantify over large areas. To address this challenge, we tested and compared two remote sensing approaches to mapping tamarisk defoliation: Disturbance Index (DI) and a decision tree method called Random Forest (RF). Based on multitemporal Landsat 5 TM imagery for 2006-2010, changes in DI and defoliation probability from RF were calculated to detect tamarisk defoliation along the banks of Green, Colorado, Dolores and San Juan rivers within the Colorado Plateau area. Defoliation mapping accuracy was assessed based on field surveys partitioned into 10 km sections of river and on regions of interest created for continuous riparian vegetation. The DI method detected 3711 ha of defoliated area in 2007, 7350 ha in 2008, 10,457 ha in 2009 and 5898 ha in 2010. The RF method detected much smaller areas of defoliation but proved to have higher accuracy, as demonstrated by accuracy assessment and sensitivity analysis, with 784 ha in 2007, 960 ha in 2008, 934 ha in 2009, and 1008 ha in 2010. Results indicate that remote sensing approaches are likely to be useful for studying spatiotemporal patterns of tamarisk defoliation as the tamarisk leaf beetle spreads throughout the western United States.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.2747/1548-1603.49.4.510","usgsCitation":"Meng, R., Dennison, P.E., Levi Jamison, van Riper, C., Nagler, P.L., Hultine, K., Bean, D., and Dudley, T., 2012, Detection of tamarisk defoliation by the northern tamarisk beetle based on multitemporal Landsat 5 thematic mapper imagery.: GIScience & Remote Sensing, v. 49, no. 4, p. 510-537, https://doi.org/10.2747/1548-1603.49.4.510.","productDescription":"28 p.","startPage":"510","endPage":"537","ipdsId":"IP-033243","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":497333,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arizona, Colorado, New Mexico, Utah, Wyoming","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -105.94724503956189,\n              41.0605388728832\n            ],\n            [\n              -109.82425133836676,\n              41.60772394040967\n            ],\n            [\n              -112.31079483911174,\n              36.432855192171345\n            ],\n            [\n              -108.78115248367467,\n              36.14982443489929\n            ],\n            [\n              -105.94724503956189,\n              41.0605388728832\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"49","issue":"4","noUsgsAuthors":false,"publicationDate":"2013-05-15","publicationStatus":"PW","contributors":{"authors":[{"text":"Meng, Ran","contributorId":363786,"corporation":false,"usgs":false,"family":"Meng","given":"Ran","affiliations":[{"id":86739,"text":"Geography, University of Utah","active":true,"usgs":false}],"preferred":false,"id":951975,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dennison, Philip E.","contributorId":363781,"corporation":false,"usgs":false,"family":"Dennison","given":"Philip","middleInitial":"E.","affiliations":[{"id":86736,"text":"Dept.of Geolgraphy, U of Utah","active":true,"usgs":false}],"preferred":false,"id":951977,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Levi Jamison","contributorId":145471,"corporation":false,"usgs":false,"family":"Levi Jamison","affiliations":[{"id":16125,"text":"SNRE, University of Arizona","active":true,"usgs":false}],"preferred":false,"id":951976,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"van Riper, Charles III 0000-0003-1084-5843 charles_van_riper@usgs.gov","orcid":"https://orcid.org/0000-0003-1084-5843","contributorId":169488,"corporation":false,"usgs":true,"family":"van Riper","given":"Charles","suffix":"III","email":"charles_van_riper@usgs.gov","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":false,"id":951973,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Nagler, Pamela L 0000-0003-0674-103X","orcid":"https://orcid.org/0000-0003-0674-103X","contributorId":363785,"corporation":false,"usgs":true,"family":"Nagler","given":"Pamela","middleInitial":"L","affiliations":[],"preferred":true,"id":951974,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Hultine, Kevin","contributorId":105634,"corporation":false,"usgs":true,"family":"Hultine","given":"Kevin","affiliations":[],"preferred":false,"id":951978,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Bean, Dan W.","contributorId":58133,"corporation":false,"usgs":true,"family":"Bean","given":"Dan W.","affiliations":[],"preferred":false,"id":951979,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Dudley, Tom","contributorId":64496,"corporation":false,"usgs":true,"family":"Dudley","given":"Tom","affiliations":[],"preferred":false,"id":951987,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

In this study, VNIRS (350–2500 nm) was employed to analyze 227 air-dried soil samples of Ultisols from a soil chronosequence in western Kenya and assess 16 SQ indicators. Partial least squares regression (PLSR) was validated using the full-site cross-validation method by grouping samples from each farm or forest site. Most suitable models successfully predicted SQ indicators (R<sup>2</sup> ≥ 0.80; ratio of performance to deviation [RPD] ≥ 2.00) including soil organic matter (OM<sub>LOI</sub>), active C, Ca, cation exchange capacity (CEC), and clay. Moderately-well predicted indicators (0.50 ≤ R<sup>2</sup> < 0.80; 1.40 ≤ RPD < 2.00) were water stable aggregation (WSA), Cu, silt, Mg, pH, sand, water content at permanent wilting point (Θ<sub>pwp</sub>), and field capacity (Θ<sub>fc</sub>). Poorly predicted indicators (R<sup>2</sup> < 0.50; RPD < 1.40) were EC, S, P, available water capacity (AWC), K, Zn, and penetration resistance. Combining VNIRS with selected field- and laboratory-measured SQ indicator values increased predictability. Furthermore, VNIRS showed moderate to substantial agreement in predicting interpretive SQ scores and a composite soil quality index (CSQI) especially when combined with directly measured SQ indicator values. In conclusion, VNIRS has good potential for low cost, rapid assessment of physical and biological SQ indicators but conventional soil chemical tests may need to be retained to provide comprehensive SQ assessments.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Soil Science Society of America Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Soil Science Society of America","doi":"10.2136/sssaj2011.0307","usgsCitation":"Kinoshita, R., Moebius-Clune, B.N., van Es, H.M., Hively, W., and Bilgilis, A.V., 2012, Strategies for soil quality assessment using VNIR gyperspectral spectroscopy in a western Kenya Chronosequence: Soil Science Society of America Journal, v. 76, no. 5, p. 1776-1788, https://doi.org/10.2136/sssaj2011.0307.","productDescription":"13 p.","startPage":"1776","endPage":"1788","numberOfPages":"13","ipdsId":"IP-033379","costCenters":[{"id":242,"text":"Eastern Geographic Science Center","active":true,"usgs":true}],"links":[{"id":474097,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.2136/sssaj2011.0307","text":"Publisher Index Page"},{"id":272032,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":272030,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2136/sssaj2011.0307"}],"country":"Kenya","otherGeospatial":"Western Kenya","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 33.91,-4.68 ], [ 33.91,5.05 ], [ 37.51,5.05 ], [ 37.51,-4.68 ], [ 33.91,-4.68 ] ] ] } } ] }","volume":"76","issue":"5","noUsgsAuthors":false,"publicationDate":"2012-09-12","publicationStatus":"PW","scienceBaseUri":"518a1460e4b061e1bd53335b","contributors":{"authors":[{"text":"Kinoshita, Rintaro","contributorId":34800,"corporation":false,"usgs":true,"family":"Kinoshita","given":"Rintaro","email":"","affiliations":[],"preferred":false,"id":477644,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moebius-Clune, Bianca N.","contributorId":62104,"corporation":false,"usgs":true,"family":"Moebius-Clune","given":"Bianca","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":477645,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"van Es, Harold M.","contributorId":97800,"corporation":false,"usgs":true,"family":"van Es","given":"Harold","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":477646,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hively, W.

Our perception is that interested members of the public and some managers believe that harvest influences North American duck populations based on calls for more conservative harvest regulations. A recent review of harvest and population dynamics of North American mallard (Anas platyrhynchos) populations (Pöysä et al. 2004) reached similar conclusions. Because of the importance of this issue, we reviewed the evidence for an impact of harvest on duck populations. Our understanding of the effects of harvest is limited because harvest effects are typically confounded with those of population density; regulations are typically most liberal when populations are greatest. This problem also exists in the current Adaptive Harvest Management Program (Conn and Kendall 2004). Consequently, even where harvest appears additive to other mortality, this may be an artifact of ignoring effects of population density. Overall, we found no compelling evidence for strong additive effects of harvest on survival in duck populations that could not be explained by other factors.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Wildlife Society","publisherLocation":"Bethesda, MD","doi":"10.1002/jwmg.370","usgsCitation":"Sedinger, J.S., and Herzog, M., 2012, Harvest and dynamics of duck populations: Journal of Wildlife Management, v. 76, no. 6, p. 1108-1116, https://doi.org/10.1002/jwmg.370.","productDescription":"9 p.","startPage":"1108","endPage":"1116","ipdsId":"IP-035604","costCenters":[{"id":216,"text":"Davis Field Station","active":false,"usgs":true}],"links":[{"id":271853,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271852,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/jwmg.370"}],"volume":"76","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-07-16","publicationStatus":"PW","scienceBaseUri":"5187716ce4b078fc9c244b5f","contributors":{"authors":[{"text":"Sedinger, James S.","contributorId":84861,"corporation":false,"usgs":false,"family":"Sedinger","given":"James","email":"","middleInitial":"S.","affiliations":[{"id":12742,"text":"University of Nevada Reno","active":true,"usgs":false}],"preferred":false,"id":472217,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Herzog, Mark P. mherzog@usgs.gov","contributorId":3965,"corporation":false,"usgs":true,"family":"Herzog","given":"Mark P.","email":"mherzog@usgs.gov","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":472216,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We undertook a novel cross-basin comparison of trophic position in two ecologically well-characterized and different groups of dominant mid-water fish consumers using amino acid nitrogen isotope compositions. We found that trophic positions estimated from the δ<sup>15</sup>N values of individual amino acids are nearly uniform within both families of these fishes across five global regions despite great variability in bulk tissue δ<sup>15</sup>N values. Regional differences in the δ<sup>15</sup>N values of phenylalanine confirmed that bulk tissue δ<sup>15</sup>N values reflect region-specific water mass biogeochemistry controlling δ<sup>15</sup>N values at the base of the food web. Trophic positions calculated from amino acid isotopic analyses (AA-TP) for lanternfishes (family Myctophidae) (AA-TP ~2.9) largely align with expectations from stomach content studies (TP ~3.2), while AA-TPs for dragonfishes (family Stomiidae) (AA-TP ~3.2) were lower than TPs derived from stomach content studies (TP~4.1). We demonstrate that amino acid nitrogen isotope analysis can overcome shortcomings of bulk tissue isotope analysis across biogeochemically distinct systems to provide globally comparative information regarding marine food web structure.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"PLoS ONE","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"PLOS","publisherLocation":"San Fransicso, CA","doi":"10.1371/journal.pone.0050133","usgsCitation":"Choy, C.A., Davison, P.C., Drazen, J.C., Flynn, A., Gier, E.J., Hoffman, J.C., McClain-Counts, J., Miller, T.W., Popp, B.N., Ross, S., and Sutton, T.T., 2012, Global trophic position comparison of two dominant mesopelagic fish families (Myctophidae, Stomiidae) using amino acid nitrogen isotopic analyses: PLoS ONE, v. 7, no. 11, p. 1-8, https://doi.org/10.1371/journal.pone.0050133.","productDescription":"e50133; 8 p.","startPage":"1","endPage":"8","onlineOnly":"Y","additionalOnlineFiles":"Y","temporalStart":"2007-01-01","temporalEnd":"2011-12-31","ipdsId":"IP-033294","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":474098,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0050133","text":"Publisher Index Page"},{"id":271850,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271849,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1371/journal.pone.0050133"},{"id":271851,"type":{"id":11,"text":"Document"},"url":"https://www.plosone.org/article/fetchObjectAttachment.action;jsessionid=9CB952656838B0A2ADDCA036CD4367DC?uri=info%3Adoi%2F10.1371%2Fjournal.pone.0050133&representation=PDF"}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 155.0,-43.0 ], [ 155.0,60.0 ], [ -27.0,60.0 ], [ -27.0,-43.0 ], [ 155.0,-43.0 ] ] ] } } ] }","volume":"7","issue":"11","noUsgsAuthors":false,"publicationDate":"2012-11-28","publicationStatus":"PW","scienceBaseUri":"5187716ae4b078fc9c244b57","contributors":{"authors":[{"text":"Choy, C.

However, the Automated Cloud-Cover Assessment (CCA) (ACCA) algorithm used on Landsat 7 requires a thermal band and is thus not suited for OLI. There will be a thermal instrument on the Landsat Data Continuity Mission (LDCM)-the Thermal Infrared Sensor-which may not be available during all OLI collections. This illustrates a need for CCA for LDCM in the absence of thermal data. To research possibilities for full-resolution OLI cloud assessment, a global data set of 207 Landsat 7 scenes with manually generated cloud masks was created. It was used to evaluate the ACCA algorithm, showing that the algorithm correctly classified 79.9% of a standard test subset of 3.95 109 pixels. The data set was also used to develop and validate two successor algorithms for use with OLI data-one derived from an off-the-shelf machine learning package and one based on ACCA but enhanced by a simple neural network. These comprehensive CCA algorithms were shown to correctly classify pixels as cloudy or clear 88.5% and 89.7% of the time, respectively.","language":"English","publisher":"Institute of Electrical and Electronics Engineers","doi":"10.1109/TGRS.2011.2164087","usgsCitation":"Scaramuzza, P., Bouchard, M., and Dwyer, J.L., 2012, Development of the Landsat Data Continuity Mission cloud-cover assessment algorithms: IEEE Transactions on Geoscience and Remote Sensing, v. 50, no. 4, p. 1140-1154, https://doi.org/10.1109/TGRS.2011.2164087.","productDescription":"15 p.","startPage":"1140","endPage":"1154","ipdsId":"IP-020443","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":270623,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"50","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5180d9d9e4b0df838b924d29","contributors":{"authors":[{"text":"Scaramuzza, Pat 0000-0002-2616-8456 pscar@usgs.gov","orcid":"https://orcid.org/0000-0002-2616-8456","contributorId":3970,"corporation":false,"usgs":true,"family":"Scaramuzza","given":"Pat","email":"pscar@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":true,"id":473298,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bouchard, M.A. 0000-0002-6353-3491","orcid":"https://orcid.org/0000-0002-6353-3491","contributorId":13023,"corporation":false,"usgs":true,"family":"Bouchard","given":"M.A.","affiliations":[],"preferred":false,"id":473300,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dwyer, John L. 0000-0002-8281-0896","orcid":"https://orcid.org/0000-0002-8281-0896","contributorId":6136,"corporation":false,"usgs":true,"family":"Dwyer","given":"John","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":473299,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Under transformations that stabilize data and model-parameter variances, the most likely Poisson-event occurrence rate, $k/\\tau$, applies for frequentist inference and, also, for Bayesian inference with a Jeffreys prior that ensures posterior invariance under changes of variables. Frequentist confidence intervals and Bayesian (Jeffreys) credibility intervals are approximately the same and easy to calculate: $(1/\\tau)[(\\sqrt{k} - z/2)^{2},(\\sqrt{k} + z/2)^{2}]$, where $z$ is a parameter that specifies the width, $z=1$ ($z=2$) corresponding to $1\\sigma$, $68.3\\%$ ($2\\sigma$, $95.4\\%$). If only a few events have been observed, as is usually the case for extreme events, then these \"error-bar\" intervals might be considered to be relatively wide. From historical records, we estimate most likely long-term occurrence rates, 10-yr occurrence probabilities, and intervals of frequentist confidence and Bayesian credibility for large earthquakes, explosive volcanic eruptions, and magnetic storms.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geophysical Research Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"AGU","publisherLocation":"Washington, D.C.","doi":"10.1029/2012GL051431","usgsCitation":"Love, J.J., 2012, Credible occurrence probabilities for extreme geophysical events: earthquakes, volcanic eruptions, magnetic storms: Geophysical Research Letters, v. 39, no. 10, L10301, https://doi.org/10.1029/2012GL051431.","productDescription":"L10301","ipdsId":"IP-037733","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":474100,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2012gl051431","text":"Publisher Index Page"},{"id":271365,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271364,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2012GL051431"}],"volume":"39","issue":"10","noUsgsAuthors":false,"publicationDate":"2012-05-18","publicationStatus":"PW","scienceBaseUri":"51764ddbe4b0f989f99e008e","contributors":{"authors":[{"text":"Love, Jeffrey J. 0000-0002-3324-0348 jlove@usgs.gov","orcid":"https://orcid.org/0000-0002-3324-0348","contributorId":760,"corporation":false,"usgs":true,"family":"Love","given":"Jeffrey","email":"jlove@usgs.gov","middleInitial":"J.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":476944,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The objectives of the study were to understand the geologic evolution of Cat Island relative to other barrier islands in the northern Gulf of Mexico and to identify relationships between the geologic history, present day morphology, and sediment distribution.  This report contains data from the bathymetry and side-scan sonar portion of the study collected during two geophysical cruises. Interferometric swath bathymetry and side-scan sonar data were collected aboard the RV G.K. Gilbert September 7-15, 2010. Single-beam bathymetry was collected in shallow water around the island (< 2 meter (m)) from the RV Streeterville from September 28 to October 2, 2010, to cover the data gap between the landward limit of the previous cruise and the shoreline.  This report serves as an archive of processed interferometric swath and single-beam bathymetry and side scan sonar data. GIS data products include a 50-m cell size interpolated gridded bathymetry surface, trackline maps, and an acoustic side-scan sonar image. Additional files include error analysis maps, Field Activity Collection System (FACS) logs, and formal Federal Geographic Data Committee (FDGC) metadata.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ds739","usgsCitation":"Buster, N.A., Pfeiffer, W.R., Miselis, J.L., Kindinger, J.L., Wiese, D.S., and Reynolds, B., 2012, Bathymetry and acoustic backscatter data collected in 2010 from Cat Island, Mississippi: U.S. Geological Survey Data Series 739, HTML Document: Abstract; Introduction; Survey Overview; Data Acquisition; Data Processing; Error Analysis; Survey Products; Data Downloads; Logs; Acronyms; Acknowledgements; References, https://doi.org/10.3133/ds739.","productDescription":"HTML Document: Abstract; Introduction; Survey Overview; Data Acquisition; Data Processing; Error Analysis; Survey Products; Data Downloads; Logs; Acronyms; Acknowledgements; References","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":271622,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":271621,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/ds/739/index.html"}],"country":"United States","state":"Alabama;Mississippi","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -89.25,30.15 ], [ -89.25,30.3 ], [ -89,30.3 ], [ -89,30.15 ], [ -89.25,30.15 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5180e7e4e4b0df838b924d55","contributors":{"authors":[{"text":"Buster, Noreen A. 0000-0001-5069-9284 nbuster@usgs.gov","orcid":"https://orcid.org/0000-0001-5069-9284","contributorId":3750,"corporation":false,"usgs":true,"family":"Buster","given":"Noreen","email":"nbuster@usgs.gov","middleInitial":"A.","affiliations":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":478064,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pfeiffer, William R. wpfeiffer@usgs.gov","contributorId":3725,"corporation":false,"usgs":true,"family":"Pfeiffer","given":"William","email":"wpfeiffer@usgs.gov","middleInitial":"R.","affiliations":[],"preferred":true,"id":478063,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Miselis, Jennifer L. 0000-0002-4925-3979 jmiselis@usgs.gov","orcid":"https://orcid.org/0000-0002-4925-3979","contributorId":3914,"corporation":false,"usgs":true,"family":"Miselis","given":"Jennifer","email":"jmiselis@usgs.gov","middleInitial":"L.","affiliations":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":478065,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kindinger, Jack L. jkindinger@usgs.gov","contributorId":815,"corporation":false,"usgs":true,"family":"Kindinger","given":"Jack","email":"jkindinger@usgs.gov","middleInitial":"L.","affiliations":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":478061,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wiese, Dana S. dwiese@usgs.gov","contributorId":2476,"corporation":false,"usgs":true,"family":"Wiese","given":"Dana","email":"dwiese@usgs.gov","middleInitial":"S.","affiliations":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":478062,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Reynolds, B.J.","contributorId":47874,"corporation":false,"usgs":true,"family":"Reynolds","given":"B.J.","email":"","affiliations":[],"preferred":false,"id":478066,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

This deployment was undertaken as part of a coordinated federal emergency response as outlined by the Stafford Act under a directed mission assignment by the Federal Emergency Management Agency. Storm tide, as defined by National Oceanic and Atmospheric Administration (NOAA; National Oceanic and Atmospheric Administration, 2008), is the water-level rise generated by a combination of storm surge and astronomical tide during a coastal storm.  Hurricane Isaac initially made landfall on the coast of Louisiana in Plaquemines Parish on August 28, 2012, as a Category 1 hurricane on the Saffir–Simpson Hurricane Wind Scale (National Weather Service, 1974) and then stalled over southern Louisiana for several days, causing prolonged storm-tide impacts. A total of 188 water-level and wave-height sensors were deployed at 127 locations during August 27–28 prior to landfall. More than 90 percent of the sensors and all high-water marks (HWMs) were recovered and surveyed to North American Vertical Datum of 1988 (NAVD 88) within 7 days of the Isaac landfall. Only a handful of sensors in the Plaquemines Parish area of Louisiana could not be retrieved until weeks later due to prolonged flooding in the area. Data collected from this event can be used to evaluate the performance of storm-tide models for maximum and incremental water level and flood extent and the site-specific effects of storm tide on natural and anthropogenic features of the environment.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20121263","collaboration":"Prepared under a mission assignment with the Federal Emergency Management Agency","usgsCitation":"McCallum, B.E., McGee, B.D., Kimbrow, D.R., Runner, M.S., Painter, J.A., Frantz, E.R., and Gotvald, A.J., 2012, Monitoring storm tide and flooding from Hurricane Isaac along the Gulf Coast of the United States, August 2012: U.S. Geological Survey Open-File Report 2012-1263, Report:  ii, 26 p.; 6 Tables, https://doi.org/10.3133/ofr20121263.","productDescription":"Report:  ii, 26 p.; 6 Tables","numberOfPages":"30","onlineOnly":"N","additionalOnlineFiles":"Y","ipdsId":"IP-042625","costCenters":[{"id":502,"text":"Office of Surface Water","active":true,"usgs":true},{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":271140,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20121263.JPG"},{"id":271126,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2012/1263/"},{"id":271129,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2012/1263/pdf/ofr2012-1263.pdf","text":"Report"},{"id":271131,"type":{"id":27,"text":"Table"},"url":"https://pubs.usgs.gov/of/2012/1263/downloads/Table1-Isaac.xlsx","text":"Table 1 -
