We used satellite-linked transmitters to obtain sequential information about location and haul-out state for Pacific walruses, Odobenus rosmarus divergens (Il-liger, 1815), in the Bering Sea during April of 2004, 2005, and 2006. We used these data in a generalized mixed model of haul-out bout durations and a hierarchical Bayesian model of haul-out probabilities to assess factors related to walrus haul-out behavior, and provide the first predictive model of walrus haul-out behavior in sea ice habitat. Average haul-out bout duration was 9 h, but durations of haul-out bouts tended to increase with durations of preceding in-water bouts. On aver-age, tagged walruses spent only about 17% of their time hauled out on sea ice. Probability of being hauled out decreased with wind speed, increased with temperature, and followed a diurnal cycle with the highest values in the evening. Our haul-out probability model can be used to estimate the proportion of the population that is unavailable for detection in spring surveys of Pacific walruses on sea ice.","language":"English","publisher":"Candadian Science Publishing","doi":"10.1139/Z09-098","issn":"00084301","usgsCitation":"Udevitz, M.S., Jay, C.V., Fischbach, A., and Garlich-Miller, J., 2009, Modeling haul-out behavior of walruses in Bering Sea ice: Canadian Journal of Zoology, v. 87, no. 12, p. 1111-1128, https://doi.org/10.1139/Z09-098.","productDescription":"18 p.","startPage":"1111","endPage":"1128","numberOfPages":"18","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":244312,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"87","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5bfde4b0c8380cd6f964","contributors":{"authors":[{"text":"Udevitz, Mark S. 0000-0003-4659-138X mudevitz@usgs.gov","orcid":"https://orcid.org/0000-0003-4659-138X","contributorId":3189,"corporation":false,"usgs":true,"family":"Udevitz","given":"Mark","email":"mudevitz@usgs.gov","middleInitial":"S.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":453061,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jay, Chadwick V. 0000-0002-9559-2189 cjay@usgs.gov","orcid":"https://orcid.org/0000-0002-9559-2189","contributorId":192736,"corporation":false,"usgs":true,"family":"Jay","given":"Chadwick","email":"cjay@usgs.gov","middleInitial":"V.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":453059,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fischbach, Anthony S. 0000-0002-6555-865X afischbach@usgs.gov","orcid":"https://orcid.org/0000-0002-6555-865X","contributorId":200780,"corporation":false,"usgs":true,"family":"Fischbach","given":"Anthony S.","email":"afischbach@usgs.gov","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":453058,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Garlich-Miller, J.

Because of the large number of bridge sites to be evaluated, we developed a tool that makes use of parameters not typically considered in site-specific liquefaction investigations. We assessed geologic, topographic, seismic hazard, and subsurface conditions at about 100 sites of past liquefaction in California. Among the parameters we found common to many of these sites are: (a) low elevations, (b) proximity to a water body, and (c) presence of geologically youthful deposits or artificial fill materials. The nature of the study necessitated the use of readily available data, preferably datasets that are consistent across the state. The screening tool we provided to Caltrans makes use of the following parameters: (1) proximity to a water body, (2) whether the bridge crosses a water body, (3) the age of site geologic materials and the environment in which the materials were deposited, as discerned from available digital geologic maps, (4) probabilistic shaking estimates, (5) the site elevation, (6) information from available liquefaction hazard maps [covering the 9-county San Francisco Bay Area and Ventura County] and California Geological Survey (CGS) Zones of Required Investigation. For bridge sites at which subsurface boring data were available (from CGS' existing database), we calculated Displacement Potential Index values using a methodology developed by Allison Faris and Jiaer Wu. Caltrans' staff will use this hazard-screening tool, along with other tools focused on bridges and foundations, to prioritize site-specific investigations. ?? 2009 ASCE.","largerWorkTitle":"TCLEE 2009: Lifeline Earthquake Engineering in a Multihazard Environment","conferenceTitle":"2009 ASCE Technical Council on Lifeline Earthquake Engineering Conference, TCLEE 2009: Lifeline Earthquake Engineering in a Multihazard Environment","conferenceDate":"28 June 2009 through 1 July 2009","conferenceLocation":"Oakland, CA","language":"English","doi":"10.1061/41050(357)55","isbn":"9780784410509","usgsCitation":"Knudsen, K.L., Bott, J., Woods, M., and McGuire, T., 2009, Development of a liquefaction hazard screening tool for caltrans bridge sites, <i>in</i> TCLEE 2009: Lifeline Earthquake Engineering in a Multihazard Environment, v. 357, Oakland, CA, 28 June 2009 through 1 July 2009, https://doi.org/10.1061/41050(357)55.","startPage":"55","costCenters":[],"links":[{"id":217422,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/41050(357)55"},{"id":245368,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"357","noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"505a003be4b0c8380cd4f660","contributors":{"authors":[{"text":"Knudsen, Kathy L.","contributorId":41188,"corporation":false,"usgs":false,"family":"Knudsen","given":"Kathy","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":459261,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bott, J.D.J.","contributorId":80519,"corporation":false,"usgs":true,"family":"Bott","given":"J.D.J.","email":"","affiliations":[],"preferred":false,"id":459263,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Woods, M.O.","contributorId":69820,"corporation":false,"usgs":true,"family":"Woods","given":"M.O.","email":"","affiliations":[],"preferred":false,"id":459262,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McGuire, T.L.","contributorId":11036,"corporation":false,"usgs":true,"family":"McGuire","given":"T.L.","email":"","affiliations":[],"preferred":false,"id":459260,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Research into long-lived predators has assumed that adults have uniform impacts on prey regardless of age. Here we use longitudinal data from repeated observations of individually-known wolves (Canis lupus) hunting elk (Cervus elaphus) in Yellowstone National Park to demonstrate that adult predatory performance declines with age and that an increasing ratio of senescent individuals in the wolf population depresses the rate of prey offtake. Because this ratio fluctuates independently of population size, predatory senescence may cause wolf populations of equal size but different age structure to have different impacts on prey populations. These findings suggest that predatory senescence is an important, though overlooked, factor affecting predator-prey dynamics. ?? 2009 Blackwell Publishing Ltd/CNRS.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1461-0248.2009.01385.x","issn":"1461023X","usgsCitation":"MacNulty, D., Smith, D., Vucetich, J., Mech, L., Stahler, D., and Packer, C., 2009, Predatory senescence in ageing wolves: Ecology Letters, v. 12, no. 12, p. 1347-1356, https://doi.org/10.1111/j.1461-0248.2009.01385.x.","startPage":"1347","endPage":"1356","numberOfPages":"10","costCenters":[],"links":[{"id":476437,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1461-0248.2009.01385.x","text":"Publisher Index Page"},{"id":217145,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1461-0248.2009.01385.x"},{"id":245064,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"12","noUsgsAuthors":false,"publicationDate":"2009-11-08","publicationStatus":"PW","scienceBaseUri":"505a817fe4b0c8380cd7b570","contributors":{"authors":[{"text":"MacNulty, D.R.","contributorId":7661,"corporation":false,"usgs":true,"family":"MacNulty","given":"D.R.","email":"","affiliations":[],"preferred":false,"id":460217,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smith, D.W.","contributorId":24726,"corporation":false,"usgs":true,"family":"Smith","given":"D.W.","email":"","affiliations":[],"preferred":false,"id":460218,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Vucetich, J.A.","contributorId":36098,"corporation":false,"usgs":true,"family":"Vucetich","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":460219,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mech, L.D. 0000-0003-3944-7769","orcid":"https://orcid.org/0000-0003-3944-7769","contributorId":75466,"corporation":false,"usgs":false,"family":"Mech","given":"L.D.","email":"","affiliations":[],"preferred":false,"id":460221,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Stahler, D.R.","contributorId":90107,"corporation":false,"usgs":true,"family":"Stahler","given":"D.R.","email":"","affiliations":[],"preferred":false,"id":460222,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Packer, C.","contributorId":45532,"corporation":false,"usgs":true,"family":"Packer","given":"C.","email":"","affiliations":[],"preferred":false,"id":460220,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

We used 18 years of color-banding data and multistate capture-recapture models to test whether habitat quality within territories influences survival and detection probability of breeding Florida Scrub-Jays (Aphelocoma coerulescens) and to estimate bird transition probabilities from one territory quality state to another. Our study sites were along central Florida's Atlantic coast and included two of the four largest metapopulations within the species range. We developed Markov models for habitat transitions and compared these to bird transition probabilities. Florida Scrub-Jay detection probabilities ranged from 0.88 in the tall territory state to 0.99 in the optimal state; detection probabilities were intermediate in the short state. Transition probabilities were similar for birds and habitat in grid cells mapped independently of birds. Thus, bird transitions resulted primarily from habitat transitions between states over time and not from bird movement. Survival ranged from 0.71 in the short state to 0.82 in the optimal state, with tall states being intermediate. We conclude that average Florida Scrub-Jay survival will remain at levels that lead to continued population declines because most current habitat quality is only marginally suitable across most of the species range. Improvements in habitat are likely to be slow and difficult because tall states are resistant to change and the optimal state represents an intermediate transitional stage. The multistate modeling approach to quantifying survival and habitat transition probabilities is useful for quantifying habitat transition probabilities and comparing them to bird transition probabilities to test for habitat selection in dynamic environments. ?? 2009 by the Ecological society ot America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/08-1123.1","issn":"00129658","usgsCitation":"Breininger, D., Nichols, J., Carter, G., and Oddy, D., 2009, Habitat-specific breeder survival of Florida Scrub-Jays: Inferences from multistate models: Ecology, v. 90, no. 11, p. 3180-3189, https://doi.org/10.1890/08-1123.1.","startPage":"3180","endPage":"3189","numberOfPages":"10","costCenters":[],"links":[{"id":501653,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://stars.library.ucf.edu/facultybib2000/7048","text":"External Repository"},{"id":216188,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/08-1123.1"},{"id":244041,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"90","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2f4ce4b0c8380cd5cc75","contributors":{"authors":[{"text":"Breininger, D.R.","contributorId":62856,"corporation":false,"usgs":true,"family":"Breininger","given":"D.R.","affiliations":[],"preferred":false,"id":451561,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nichols, J.D. 0000-0002-7631-2890","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":14332,"corporation":false,"usgs":true,"family":"Nichols","given":"J.D.","affiliations":[],"preferred":false,"id":451558,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Carter, G.M.","contributorId":54429,"corporation":false,"usgs":true,"family":"Carter","given":"G.M.","email":"","affiliations":[],"preferred":false,"id":451560,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Oddy, D.M.","contributorId":30845,"corporation":false,"usgs":true,"family":"Oddy","given":"D.M.","email":"","affiliations":[],"preferred":false,"id":451559,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Nontronite, montmorillonite, kaolinite, and hydrated silica have been identified throughout the region using data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM). In addition, saponite has been identified in one observation within a crater. These individual minerals are identified and distinguished by features at 1.38-1.42, ???1.91, and 2.17-2.41 ??m. There are two main phyllosilicate units in the Mawrth Vallis region. The lowermost unit is nontronite bearing, unconformably overlain by an Al-phyllosilicate unit containing montmorillonite plus hydrated silica, with a thin layer of kaolinite plus hydrated silica at the top of the unit. These two units are draped by a spectrally unremarkable capping unit. Smectites generally form in neutral to alkaline environments, while kaolinite and hydrated silica typically form in slightly acidic conditions; thus, the observed phyllosilicates may reflect a change in aqueous chemistry. Spectra retrieved near the boundary between the nontronite and Al-phyllosilicate units exhibit a strong positive slope from 1 to 2 ??m, likely from a ferrous component within the rock. This ferrous component indicates either rapid deposition in an oxidizing environment or reducing conditions. Formation of each of the phyllosilicate minerals identified requires liquid water, thus indicating a regional wet period in the Noachian when these units formed. The two main phyllosilicate units may be extensive layers of altered volcanic ash. Other potential formational processes include sediment deposition into a marine or lacustrine basin or pedogenesis.

The ??11B values of the Holocene corals vary significantly, ranging from 22.2??? to 25.5???. The paleo-pH records of the SCS, reconstructed from the ??11B data, were not stable as previously thought but show a gradual increase from the Holocene thermal optimal and a sharp decrease to modern values. The latter is likely caused by the large amount of anthropogenic CO2 emissions since the Industrial Revolution but variations of atmospheric pCO2 cannot explain the pH change of the SCS before the Industrial Revolution. We suggest that variations of monsoon intensity during the mid-late Holocene may have driven the sea surface pH increase from the mid to late Holocene. Results of this study indicate that the impact of anthropogenic atmospheric CO2 emissions may have reversed the natural pH trend in the SCS since the mid-Holocene. Such ocean pH records in the current interglacial period can help us better understand the physical and biological controls on ocean pH and possibly predict the long-term impact of climate change on future ocean acidification. ?? 2008 Elsevier Ltd.

As part of the Carolinas Coastal Change Processes Project, a geologic framework study in June of 2008 by the Woods Hole Coastal and Marine Science Center's Sea Floor Mapping Group focused on the seaward limit of Diamond Shoals and provided high resolution bathymetric data, surficial sediment characteristics, and subsurface geologic stratigraphy. These data also provided unprecedented guidance to identify deployment locations for tripods and moorings to investigate the processes that control sediment transport at Diamond Shoals. Equipment was deployed at three sites from early January, 2009 through early May, 2009: north and south of the shoals at 15 m depth, and at the tip at 24 m depth. Many strong storm systems were recorded during that time period. Mounted on the tripods were instruments to measure surface waves, pressure, current velocity, bottom turbulence, suspended-sediment profiles, and sea-floor sand-ripple bedforms. Many instruments were designed and programmed to sample in high resolution in time and space, as fast as 8 Hz hourly bursts and as small as 6 cm bin sizes in near bottom profiles. A second tripod at the north site also held a visual camera system and sonar imaging system which document seafloor bedforms. The region is known for its dynamics, and one of the tripods tipped over towards the end of the experiment. A preliminary look at the data suggests the region is characterized by high energy. Raw data from a burst recorded at the south site on Mar. 26<sup>th</sup> show instantaneous flow speed at 150 cm/s at 0.5 m above the seabed. This paper reports preliminary highlights of the observations, based on raw data, and lessons learned from a deployment of large tripod systems in such a dynamic location. ??2009 MTS.","largerWorkTitle":"MTS/IEEE Biloxi - Marine Technology for Our Future: Global and Local Challenges, OCEANS 2009","conferenceTitle":"MTS/IEEE Biloxi - Marine Technology for Our Future: Global and Local Challenges, OCEANS 2009","conferenceDate":"26 October 2009 through 29 October 2009","conferenceLocation":"Biloxi, MS","language":"English","isbn":"9781424449606","usgsCitation":"Martini, M., Armstrong, B., and Warner, J., 2009, High resolution near-bed observations in winter near Cape Hatteras, North Carolina, <i>in</i> MTS/IEEE Biloxi - Marine Technology for Our Future: Global and Local Challenges, OCEANS 2009, Biloxi, MS, 26 October 2009 through 29 October 2009.","costCenters":[],"links":[{"id":243143,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a30cce4b0c8380cd5d962","contributors":{"authors":[{"text":"Martini, M.","contributorId":24909,"corporation":false,"usgs":true,"family":"Martini","given":"M.","email":"","affiliations":[],"preferred":false,"id":450567,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Armstrong, B.","contributorId":15845,"corporation":false,"usgs":true,"family":"Armstrong","given":"B.","email":"","affiliations":[],"preferred":false,"id":450566,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Warner, J.C.","contributorId":46644,"corporation":false,"usgs":true,"family":"Warner","given":"J.C.","email":"","affiliations":[],"preferred":false,"id":450568,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Spectral distance among sites has proven to be a powerful approach for detecting species composition variability. Regression analysis of species similarity versus spectral distance may allow us to quantitatively estimate how beta-diversity in species changes with respect to spectral and ecological variability. In classical regression analysis, the residual sum of squares is minimized for the mean of the dependent variable distribution. However, many ecological datasets are characterized by a high number of zeroes that can add noise to the regression model. Quantile regression can be used to evaluate trend in the upper quantiles rather than a mean trend across the whole distribution of the dependent variable. In this paper, we used ordinary least square (OLS) and quantile regression to estimate the decay of species similarity versus spectral distance. The achieved decay rates were statistically nonzero (p &lt; 0.05) considering both OLS and quantile regression. Nonetheless, OLS regression estimate of mean decay rate was only half the decay rate indicated by the upper quantiles. Moreover, the intercept value, representing the similarity reached when spectral distance approaches zero, was very low compared with the intercepts of upper quantiles, which detected high species similarity when habitats are more similar. In this paper we demonstrated the power of using quantile regressions applied to spectral distance decay in order to reveal species diversity patterns otherwise lost or underestimated by ordinary least square regression.</i></p>","language":"English","publisher":"American Society for Photogrammetry and Remote Sensing","doi":"10.14358/pers.75.10.1225","issn":"00991112","usgsCitation":"Rocchinl, D., Nagendra, H., Ghate, R., and Cade, B., 2009, Spectral distance decay: Photogrammetric Engineering and Remote Sensing, v. 75, no. 10, p. 1225-1230, https://doi.org/10.14358/pers.75.10.1225.","productDescription":"6 p.","startPage":"1225","endPage":"1230","numberOfPages":"6","costCenters":[],"links":[{"id":476313,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.14358/pers.75.10.1225","text":"Publisher Index Page"},{"id":384247,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"75","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b953ce4b08c986b31ae01","contributors":{"authors":[{"text":"Rocchinl, D.","contributorId":40825,"corporation":false,"usgs":true,"family":"Rocchinl","given":"D.","email":"","affiliations":[],"preferred":false,"id":452590,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nagendra, H.","contributorId":69809,"corporation":false,"usgs":true,"family":"Nagendra","given":"H.","email":"","affiliations":[],"preferred":false,"id":452592,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ghate, R.","contributorId":12289,"corporation":false,"usgs":true,"family":"Ghate","given":"R.","email":"","affiliations":[],"preferred":false,"id":452589,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Cade, B.S.","contributorId":47315,"corporation":false,"usgs":true,"family":"Cade","given":"B.S.","affiliations":[],"preferred":false,"id":452591,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Parameter flexibility is allowed by using a highly parameterized approach with the level of complexity informed by the data. Despite the effort to adhere to the ideal of minimal a priori structure imposed on the problem, extreme contrasts in parameters can result in the need to censor correlation across hydrostratigraphic bounding surfaces.

Invasive alien species monitoring and detection networks (such as the Invasive Plant Atlas of New England and the Invasive Plant Atlas of the MidSouth) generate occurrence data at local and regional levels within the United States, which are shared through the US National Institute of Invasive Species Science. The Inter-American Biodiversity Information Network's Invasives Information Network (I3N), facilitates cooperation on sharing invasive species occurrence data throughout the Western Hemisphere. The I3N and other national and regional networks expose their data globally via the Global Invasive Species Information Network (GISIN). International and interdisciplinary cooperation on data sharing strengthens cooperation on strategies and responses to invasions. However, limitations to effective collaboration among invasive species networks leading to successful early detection and rapid response to invasive species include: lack of interoperability; data accessibility; funding; and technical expertise. This paper proposes various solutions to these obstacles at different geographic levels and briefly describes success stories from the invasive species information networks mentioned above. Using biological informatics to facilitate global information sharing is especially critical in invasive species science, as research has shown that one of the best indicators of the invasiveness of a species is whether it has been invasive elsewhere. Data must also be shared across disciplines because natural history information (e.g. diet, predators, habitat requirements, etc.) about a species in its native range is vital for effective prevention, detection, and rapid response to an invasion. Finally, it has been our experience that sharing information, including invasive species dispersal mechanisms and rates, impacts, and prevention and control strategies, enables resource managers and decision-makers to mount a more effective response to biological invasions.","language":"English","publisher":"Taylor and Francis","doi":"10.1080/14888386.2009.9712839","usgsCitation":"Simpson, A., Jarnevich, C.S., Madsen, J., Westbrooks, R.G., Fournier, C., Mehrhoff, L., Browne, M., Graham, J., and Sellers, E.A., 2009, Invasive species information networks: Collaboration at multiple scales for prevention, early detection, and rapid response to invasive alien species: Biodiversity, v. 10, no. 2-3, p. 5-13, https://doi.org/10.1080/14888386.2009.9712839.","productDescription":"9 p.","startPage":"5","endPage":"13","numberOfPages":"9","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true},{"id":37226,"text":"Core Science Analytics, Synthesis, and Libraries","active":true,"usgs":true}],"links":[{"id":244380,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"10","issue":"2-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3e26e4b0c8380cd63b4a","contributors":{"authors":[{"text":"Simpson, Annie 0000-0001-8338-5134 asimpson@usgs.gov","orcid":"https://orcid.org/0000-0001-8338-5134","contributorId":127,"corporation":false,"usgs":true,"family":"Simpson","given":"Annie","email":"asimpson@usgs.gov","affiliations":[{"id":208,"text":"Core Science Analytics and Synthesis","active":true,"usgs":true}],"preferred":true,"id":451053,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jarnevich, Catherine S. 0000-0002-9699-2336 jarnevichc@usgs.gov","orcid":"https://orcid.org/0000-0002-9699-2336","contributorId":3424,"corporation":false,"usgs":true,"family":"Jarnevich","given":"Catherine","email":"jarnevichc@usgs.gov","middleInitial":"S.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":451055,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Madsen, John","contributorId":178747,"corporation":false,"usgs":false,"family":"Madsen","given":"John","affiliations":[],"preferred":false,"id":451052,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Westbrooks, Randy G.","contributorId":147074,"corporation":false,"usgs":false,"family":"Westbrooks","given":"Randy","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":451051,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fournier, Christine","contributorId":178748,"corporation":false,"usgs":false,"family":"Fournier","given":"Christine","email":"","affiliations":[],"preferred":false,"id":451057,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mehrhoff, Les","contributorId":178749,"corporation":false,"usgs":false,"family":"Mehrhoff","given":"Les","affiliations":[],"preferred":false,"id":451050,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Browne, Michael","contributorId":178752,"corporation":false,"usgs":false,"family":"Browne","given":"Michael","email":"","affiliations":[],"preferred":false,"id":451054,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Graham, Jim","contributorId":37608,"corporation":false,"usgs":true,"family":"Graham","given":"Jim","email":"","affiliations":[],"preferred":false,"id":451056,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Sellers, Elizabeth A. 0000-0003-4676-2994 esellers@usgs.gov","orcid":"https://orcid.org/0000-0003-4676-2994","contributorId":4704,"corporation":false,"usgs":true,"family":"Sellers","given":"Elizabeth","email":"esellers@usgs.gov","middleInitial":"A.","affiliations":[{"id":208,"text":"Core Science Analytics and Synthesis","active":true,"usgs":true}],"preferred":true,"id":451058,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Application of the test requires that the sample be unbiased and the outcomes be independent and identically distributed, conditions that are violated in several degrees by spatially continuous attributes, such as topographical elevation. A generalized form of the bootstrap method is used here for the purpose of modeling the distribution of the statistic D of the Kolmogorov-Smirnov test. The innovation is in the resampling, which in the traditional formulation of bootstrap is done by drawing from the empirical sample with replacement presuming independence. The generalization consists of preparing resamplings with the same spatial correlation as the empirical sample. This is accomplished by reading the value of unconditional stochastic realizations at the sampling locations, realizations that are generated by simulated annealing. The new approach was tested by two empirical samples taken from an exhaustive sample closely following a lognormal distribution. One sample was a regular, unbiased sample while the other one was a clustered, preferential sample that had to be preprocessed. Our results show that the p-value for the spatially correlated case is always larger that the p-value of the statistic in the absence of spatial correlation, which is in agreement with the fact that the information content of an uncorrelated sample is larger than the one for a spatially correlated sample of the same size. ??

As part of a series of four papers, this paper outlines the motivation and setup of LUCHEM, and presents a model intercomparison for the present-day simulation results. Such an intercomparison provides a valuable basis to investigate the effects of different model structures on model predictions and paves the ground for the analysis of the performance of multi-model ensembles and the reliability of the scenario predictions in companion papers. In this study, we applied a set of 10 lumped, semi-lumped and fully distributed hydrological models that have been previously used in land use change studies to the low mountainous Dill catchment, Germany. Substantial differences in model performance were observed with Nash-Sutcliffe efficiencies ranging from 0.53 to 0.92. Differences in model performance were attributed to (1) model input data, (2) model calibration and (3) the physical basis of the models. The models were applied with two sets of input data: an original and a homogenized data set. This homogenization of precipitation, temperature and leaf area index was performed to reduce the variation between the models. Homogenization improved the comparability of model simulations and resulted in a reduced average bias, although some variation in model data input remained. The effect of the physical differences between models on the long-term water balance was mainly attributed to differences in how models represent evapotranspiration. Semi-lumped and lumped conceptual models slightly outperformed the fully distributed and physically based models. This was attributed to the automatic model calibration typically used for this type of models. Overall, however, we conclude that there was no superior model if several measures of model performance are considered and that all models are suitable to participate in further multi-model ensemble set-ups and land use change scenario investigations. ?? 2008 Elsevier Ltd.

Studies of calcareous nannofossil and palynomorph assemblages in the International Continental Scientific Drilling Program (ICDP)-U.S. Geological Survey (USGS) Eyreville A and B cores show the mixed-age, mixed-preservation microfossil assemblages that are typical of deposits from the upper part of the Chesapeake Bay impact structure. Sparse, poorly preserved, possibly thermally altered pollen is present within a gravelly sand interval below the granite slab at 1392 m in Eyreville core B, an interval that is otherwise barren of calcareous nannofossils and dinocysts. Gravitational collapse of watersaturated sediments from the transient crater wall resulted in the deposition of sediment clasts primarily derived from the nonmarine Cretaceous Potomac Formation. Collapse occurred before the arrival of resurge. Low pollen Thermal Alteration Index (TAI) values suggest that these sediments were not thermally altered by contact with the melt sheet. The arrival of resurge sedimentation is identified based on the presence of diamicton zones and stringers rich in glauconite and marine microfossils at 866.7 m. This horizon can be traced across the crater and can be used to identify gravitational collapse versus ocean-resurge sedimentation. Glauconitic quartz sand diamicton dominates the sediments above 618.2 m. Calcareous nannofossil and dinoflagellate data from this interval suggest that the earliest arriving resurge from the west contained little or no Cretaceous marine input, but later resurge pulses mined Cretaceous sediments east of the Watkins core in the annular trough. Additionally, the increased distance traveled by resurge to the central crater in turbulent flow conditions resulted in the disaggregation of Paleogene unconsolidated sediments. As a result, intact Paleogene clasts in Eyreville cores are rare, but clasts of semilithified Potomac Formation silts and clays are common.&nbsp;</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/2009.2458(28)","issn":"00721077","usgsCitation":"Self-Trail, J., Edwards, L.E., and Litwin, R.J., 2009, Paleontological interpretations of crater processes and infilling of synimpact sediments from the Chesapeake Bay impact structure: Special Paper of the Geological Society of America, no. 458, p. 633-654, https://doi.org/10.1130/2009.2458(28).","productDescription":"22 p.","startPage":"633","endPage":"654","numberOfPages":"22","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"links":[{"id":243278,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Chesapeake Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -77.54150390625,\n              36.73888412439431\n            ],\n            [\n              -75.157470703125,\n              36.73888412439431\n            ],\n            [\n              -75.157470703125,\n              39.70718665682654\n            ],\n            [\n              -77.54150390625,\n              39.70718665682654\n            ],\n            [\n              -77.54150390625,\n              36.73888412439431\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","issue":"458","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7435e4b0c8380cd774ef","contributors":{"authors":[{"text":"Self-Trail, Jean 0000-0002-3018-4985 jstrail@usgs.gov","orcid":"https://orcid.org/0000-0002-3018-4985","contributorId":147370,"corporation":false,"usgs":true,"family":"Self-Trail","given":"Jean","email":"jstrail@usgs.gov","affiliations":[{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true},{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"preferred":true,"id":785756,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Edwards, Lucy E. 0000-0003-4075-3317 leedward@usgs.gov","orcid":"https://orcid.org/0000-0003-4075-3317","contributorId":2647,"corporation":false,"usgs":true,"family":"Edwards","given":"Lucy","email":"leedward@usgs.gov","middleInitial":"E.","affiliations":[{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true},{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"preferred":true,"id":450716,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Litwin, Ronald J. 0000-0002-8661-1296 rlitwin@usgs.gov","orcid":"https://orcid.org/0000-0002-8661-1296","contributorId":2478,"corporation":false,"usgs":true,"family":"Litwin","given":"Ronald","email":"rlitwin@usgs.gov","middleInitial":"J.","affiliations":[{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true},{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"preferred":true,"id":450718,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Invasive removal programs on islands are conservation efforts that can also be viewed as powerful manipulative experiments, but few data are available to evaluate their effects. We collected demographic and herbivore damage data for Castilleja mollis Pennell, an endangered plant endemic to Santa Rosa Island, California, over a 12-year period before, during, and after the implementation of control for introduced cattle, deer, and elk. We used these long-term data to explore mechanisms underlying herbivore effects, assess the results of herbivore reduction at the scales of both individual plants and populations, and determine how temporal variability in herbivory and plant demography influenced responses to herbivore removals. For individual plants, herbivore effects mediated by disturbance were greater than those of grazing. Deer and elk scraping of the ground substantially increased plant mortality and dormancy and reduced flowering and growth. Stem damage from browsing did not affect survivorship but significantly reduced plant growth and flower production. Herbivore control successfully lowered damage rates, which declined steeply between 1997 and 2000 and have remained relatively low. Castilleja mollis abundances rose sharply after 1997, suggesting a positive effect of herbivore control, but then began to decline steadily again after 2003. The recent decline appears to be driven by higher mean growing season temperatures; interestingly, not only reductions in scraping damage but a period of cooler conditions were significant in explaining increases in C. mollis populations between 1997 and 2002. Our results demonstrate strong effects of introduced herbivores on both plant demography and population dynamics and show that climate-driven variation may counteract and mask positive responses to herbivore removal. Regional mean temperatures already have risen significantly over the last 50 years, suggesting that climate change could increasingly swamp the effects of management targeted at other environmental problems. Similar interactions between climate and invasive species will play an even greater role in future management, with long-term data sets like this critical to quantifying such effects. ?? 2009 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/08-1574.1","issn":"10510761","usgsCitation":"Kathryn, M.A., Thomson, D., and Chess, K., 2009, Climate alters response of an endemic island plant to removal of invasive herbivores: Ecological Applications, v. 19, no. 6, p. 1574-1584, https://doi.org/10.1890/08-1574.1.","startPage":"1574","endPage":"1584","numberOfPages":"11","costCenters":[],"links":[{"id":217777,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/08-1574.1"},{"id":245745,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"19","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f648e4b0c8380cd4c66a","contributors":{"authors":[{"text":"Kathryn, Mceachern A.","contributorId":31233,"corporation":false,"usgs":true,"family":"Kathryn","given":"Mceachern","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":458829,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thomson, D.M.","contributorId":104740,"corporation":false,"usgs":true,"family":"Thomson","given":"D.M.","email":"","affiliations":[],"preferred":false,"id":458831,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chess, K.A.","contributorId":72731,"corporation":false,"usgs":true,"family":"Chess","given":"K.A.","email":"","affiliations":[],"preferred":false,"id":458830,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

One of the most frequently used methods to preconcentrate these nuclides from such large volumes involves extraction onto three filter cartridges (a prefilter for particulate species and two MnO<sub>2</sub>-coated filters for dissolved species) connected in series. This method assumes that the extraction efficiency is uniform for both MnO<sub>2</sub>-coated cartridges, that no dissolved species are removed by the prefilter, and that any adsorbed radionuclides are not desorbed from the MnO<sub>2</sub>-coated cartridges during filtration. In this study, we utilized <sup>234</sup>Th-spiked coastal seawater and deionized water to address the removal of dissolved Th onto prefilters and MnO<sub>2</sub>-coated filter cartridges. Experimental results provide the first data that indicate (1) a small fraction of dissolved Th (&lt;6%) can be removed by the prefilter cartridge; (2) a small fraction of dissolved Th (&lt;5%) retained by the MnO<sub>2</sub> surface can also be desorbed, which undermines the assumption of uniform extraction efficiency for Th; and (3) the absolute and relative extraction efficiencies can vary widely. These experiments provide insight on the variability of the extraction efficiency of MnO <sub>2</sub>-coated filter cartridges by comparing the relative and absolute efficiencies and recommend the use of a constant efficiency on the combined activity from two filter cartridges connected in series for future studies of dissolved <sup>234</sup>Th and other radionuclides in natural waters using sequential filtration/extraction methods. ?? 2009 by the American Geophysical Union.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochemistry, Geophysics, Geosystems","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1029/2008GC002340","issn":"15252027","usgsCitation":"Baskaran, M., Swarzenski, P., and Biddanda, B., 2009, Constraints on the utility of MnO<sub>2</sub> cartridge method for the extraction of radionuclides: A case study using <sup>234</sup>Th: Geochemistry, Geophysics, Geosystems, v. 10, no. 4, https://doi.org/10.1029/2008GC002340.","costCenters":[],"links":[{"id":476336,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2008gc002340","text":"Publisher Index Page"},{"id":215232,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2008GC002340"},{"id":243021,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"10","issue":"4","noUsgsAuthors":false,"publicationDate":"2009-04-22","publicationStatus":"PW","scienceBaseUri":"5059fa11e4b0c8380cd4d903","contributors":{"authors":[{"text":"Baskaran, M.","contributorId":96627,"corporation":false,"usgs":true,"family":"Baskaran","given":"M.","affiliations":[],"preferred":false,"id":450474,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Swarzenski, P.W. 0000-0003-0116-0578","orcid":"https://orcid.org/0000-0003-0116-0578","contributorId":29487,"corporation":false,"usgs":true,"family":"Swarzenski","given":"P.W.","affiliations":[],"preferred":false,"id":450472,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Biddanda, B.A.","contributorId":92881,"corporation":false,"usgs":true,"family":"Biddanda","given":"B.A.","email":"","affiliations":[],"preferred":false,"id":450473,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The UK-DMC SLIM-6 design consists of a three-band imager with green, red, and near-infrared bands that are set to similar bandpass as Landsat bands 2, 3, and 4. The UK-DMC data consisted of imagery registered to Landsat orthorectified imagery produced from the GeoCover program. Relief displacements within the UK-DMC SLIM-6 imagery were accounted for by using global 1-km digital elevation models available through the Global Land One-km Base Elevation (GLOBE) Project. Positional accuracy and relative band-to-band accuracy were measured. Positional accuracy of the UK-DMC SLIM-6 imagery was assessed by measuring the imagery against digital orthophoto quadrangles (DOQs), which are designed to meet national map accuracy standards at 1 : 24 000 scales; this corresponds to a horizontal root-mean-square accuracy of about 6 m. The UK-DMC SLIM-6 images were typically registered to within 1.0-1.5 pixels to the DOQ mosaic images. Several radiometric artifacts like striping, coherent noise, and flat detector were discovered and studied. Indications are that the SSTL UK-DMC SLIM-6 data have few artifacts and calibration challenges, and these can be adjusted or corrected via calibration and processing algorithms.

The included species encompass a broad array of morphologies and behaviours, making them appealing for evolutionary studies, but the size of the group (ca. 600 species) has limited well-sampled higher-level phylogenetic studies. Using DNA sequence data from the nuclear RAG-1 and RAG-2 exons, we undertook a phylogenetic analysis of the Furnariides sampling 124 (more than 88%) of the genera. Basal relationships among family-level taxa differed depending on phylogenetic method, but all topologies had little nodal support, mirroring the results from earlier studies in which discerning relationships at the base of the radiation was also difficult. In contrast, branch support for family-rank taxa and for many relationships within those clades was generally high. Our results support the Melanopareidae and Grallariidae as distinct from the Rhinocryptidae and Formicariidae, respectively. Within the Furnariides our data contradict some recent phylogenetic hypotheses and suggest that further study is needed to resolve these discrepancies. Of the few genera represented by multiple species, several were not monophyletic, indicating that additional systematic work remains within furnariine families and must include dense taxon sampling. We use this study as a basis for proposing a new phylogenetic classification for the group and in the process erect new family-group names for clades having high branch support across methods. ?? 2009 The Willi Hennig Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Cladistics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1096-0031.2009.00259.x","issn":"07483007","usgsCitation":"Moyle, R., Chesser, R., Brumfield, R., Tello, J., Marchese, D., and Cracraft, J., 2009, Phylogeny and phylogenetic classification of the antbirds, ovenbirds, woodcreepers, and allies (Aves: Passeriformes: Infraorder Furnariides): Cladistics, v. 25, no. 4, p. 386-405, https://doi.org/10.1111/j.1096-0031.2009.00259.x.","startPage":"386","endPage":"405","numberOfPages":"20","costCenters":[],"links":[{"id":476244,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1096-0031.2009.00259.x","text":"Publisher Index Page"},{"id":217778,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1096-0031.2009.00259.x"},{"id":245746,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"4","noUsgsAuthors":false,"publicationDate":"2009-07-15","publicationStatus":"PW","scienceBaseUri":"505a7a55e4b0c8380cd78e6f","contributors":{"authors":[{"text":"Moyle, R.G.","contributorId":94016,"corporation":false,"usgs":true,"family":"Moyle","given":"R.G.","email":"","affiliations":[],"preferred":false,"id":458836,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chesser, R.T. 0000-0003-4389-7092","orcid":"https://orcid.org/0000-0003-4389-7092","contributorId":34616,"corporation":false,"usgs":true,"family":"Chesser","given":"R.T.","email":"","affiliations":[],"preferred":false,"id":458834,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brumfield, R.T.","contributorId":24882,"corporation":false,"usgs":true,"family":"Brumfield","given":"R.T.","email":"","affiliations":[],"preferred":false,"id":458833,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Tello, J.G.","contributorId":11859,"corporation":false,"usgs":true,"family":"Tello","given":"J.G.","email":"","affiliations":[],"preferred":false,"id":458832,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Marchese, D.J.","contributorId":106733,"corporation":false,"usgs":true,"family":"Marchese","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":458837,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Cracraft, J.","contributorId":56768,"corporation":false,"usgs":true,"family":"Cracraft","given":"J.","email":"","affiliations":[],"preferred":false,"id":458835,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

However, the performance of these rotational seismometers has not been rigorously and independently tested and characterized for earthquake monitoring purposes as is done for translational strong- and weak-motion seismometers. Quantities such as sensitivity, frequency response, resolution, and linearity are needed for the understanding of recorded rotational data. To address this need, we, with assistance from colleagues in the United States and Taiwan, have been developing performance test methodologies and equipment for rotational seismometers. In this article the performance testing methodologies are applied to samples of a commonly used commercial rotational seismometer, the eentec model R-1. Several examples were obtained for various test sequences in 2006, 2007, and 2008. Performance testing of these sensors consisted of measuring: (1) sensitivity and frequency response; (2) clip level; (3) self noise and resolution; and (4) cross-axis sensitivity, both rotational and translational. These sensor-specific results will assist in understanding the performance envelope of the R-1 rotational seismometer, and the test methodologies can be applied to other rotational seismometers.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120080247","issn":"00371106","usgsCitation":"Nigbor, R., Evans, J., and Hutt, C., 2009, Laboratory and field testing of commercial rotational seismometers: Bulletin of the Seismological Society of America, v. 99, no. 2 B, p. 1215-1227, https://doi.org/10.1785/0120080247.","startPage":"1215","endPage":"1227","numberOfPages":"13","costCenters":[],"links":[{"id":217871,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120080247"},{"id":245844,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"99","issue":"2 B","noUsgsAuthors":false,"publicationDate":"2009-05-01","publicationStatus":"PW","scienceBaseUri":"505a4101e4b0c8380cd65212","contributors":{"authors":[{"text":"Nigbor, R.L.","contributorId":30699,"corporation":false,"usgs":true,"family":"Nigbor","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":456755,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Evans, J.R.","contributorId":50526,"corporation":false,"usgs":true,"family":"Evans","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":456756,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hutt, C.
