We use radar interferograms and GPS observations to constrain models of magma accumulation and faulting at Sierra Negra volcano, Galápagos, during the years before its 2005 eruption. The data have shown ~5 m of pre-eruption uplift and multiple trapdoor faulting events on an intra-caldera fault system. We find the pattern of uplift to be consistent with an inflating sill at 2.2 km depth under the caldera. Our deformation modeling and stress-change calculations suggest that the inflating sill triggered faulting on an inward- dipping thrust fault and that the faulting in turn relieved the pressure within the sill. This sill-fault interaction tends to thicken the sill and limit its lateral extent within the area bounded by the fault.

The active ingredient in AQUI-S is isoeugenol. A method for determining isoeugenol concentrations in edible fillet tissue is needed for regulatory purposes, including surveillance and potential use in studies fulfilling human food safety data requirements if U.S. Food and Drug Administration approval is pursued. A method was developed and evaluated for determining isoeugenol concentrations in fillet tissue using relatively common procedures and equipment. The method produced accurate and precise results with fillet tissue from 10 freshwater fish species. The percentage of isoeugenol recovered from samples fortified with isoeugenol at nominal concentrations of 1, 50, and 100 microg/g for all species was always >80 and <97%. Within-day precision for samples fortified at those same concentrations was < or =10%, and day-to-day precision was < or =4.0%. Method precision with fillet tissue containing biologically incurred isoeugenol was < or =8.1%. There were no or minimal chromatographic interferences in control fillet tissue extracts from 9 of the 10 species. The method detection limits for all but one species ranged from 0.004 to 0.014 microg/g, and the quantitation limits ranged from 0.012 to 0.048 microg/g.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of AOAC International","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ingenta Connect","issn":"10603271","usgsCitation":"Meinertz, J., Schreier, T.M., and Bernardy, J., 2008, Evaluation of a method for determining concentrations of isoeugenol, an AQUI-S residue, in fillet tissue from freshwater fish species.: Journal of AOAC International, v. 91, no. 4, p. 884-891.","startPage":"884","endPage":"891","numberOfPages":"8","costCenters":[],"links":[{"id":218678,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"91","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0c31e4b0c8380cd52a86","contributors":{"authors":[{"text":"Meinertz, J.R. 0000-0002-8855-2648","orcid":"https://orcid.org/0000-0002-8855-2648","contributorId":16786,"corporation":false,"usgs":true,"family":"Meinertz","given":"J.R.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":false,"id":356996,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schreier, Theresa M. 0000-0001-7722-6292 tschreier@usgs.gov","orcid":"https://orcid.org/0000-0001-7722-6292","contributorId":3344,"corporation":false,"usgs":true,"family":"Schreier","given":"Theresa","email":"tschreier@usgs.gov","middleInitial":"M.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":356998,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bernardy, J.A.","contributorId":28567,"corporation":false,"usgs":true,"family":"Bernardy","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":356997,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70009735,"text":"70009735 - 2008 - Carbonate precipitation by the thermophilic archaeon Archaeoglobus fulgidus: A model of carbon flow for an ancient microorganism","interactions":[],"lastModifiedDate":"2018-08-10T15:42:28","indexId":"70009735","displayToPublicDate":"2008-01-01T00:00:00","publicationYear":"2008","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1012,"text":"Biogeosciences Discussions","active":true,"publicationSubtype":{"id":10}},"title":"Carbonate precipitation by the thermophilic archaeon Archaeoglobus fulgidus: A model of carbon flow for an ancient microorganism","docAbstract":"Microbial carbonate precipitation experiments were conducted using the archaeon bacteria Archaeoglobus fulgidus to determine chemical and isotopic fractionation of organic and inorganic carbon into mineral phases.

Data collected in SLC-off mode have gaps in a systematic wedge-shaped pattern outside of the central 22 km swath of the imagery; however, the spatial and spectral quality of the remaining portions of the imagery are not diminished. To explore the continued use of Landsat-7 ETM+ SLC-off imagery to characterize change in forested environments, we compare the change detection results generated from a reference image pair (a 1999 Landsat-7 ETM+ image and a 2003 Landsat-5 TM image) with change detection results generated from the same 1999 Landsat-7 ETM+ image coupled with three different 2003 Landsat-7 SLC-off products: unremediated SLC-off (i.e., with gaps); histogram-based gap-filled; and segment-based gap-filled. The results are compared on both a pixel and polygon basis; on a pixel basis, the unremediated SLC-off product missed 35% of the change identified by the reference data, and the histogram- and segment-based gap-filled products missed 23% and 21% of the change, respectively. When using forest inventory polygons as a context for change (to reduce commission error), the amount of change missed was 31%, 14%, and 12% for the each of the unremediated, histogram-based gap-filled, and segment-based gap-filled products, respectively. Our results indicate that over the time period considered, and given the types and spatial distribution of change events within our study area, the gap-filled products can provide a useful data source for change detection in forested environments. The selection of which product to use is, however, very dependent on the nature of the application and the spatial configuration of change events. ?? 2008 Government of Canada.

NLAPS converts raw satellite data into radiometrically and geometrically calibrated products. NLAPS has historically used the Internal Calibrator (IC) to calibrate the reflective bands of the Landsat-5 Thematic Mapper (TM), even though the lamps in the IC were less stable than the TM detectors, as evidenced by vicarious calibration results. In 2003, a major effort was made to model the actual TM gain change and to update NLAPS to use this model rather than the unstable IC data for radiometric calibration. The model coefficients were revised in 2007 to reflect greater understanding of the changes in the TM responsivity. While the calibration updates are important to users with recently processed data, the processing system no longer calculates the original IC gain or offset. For specific applications, it is useful to have a record of the gain and offset actually applied to the older data. Thus, the NLAPS calibration database was used to generate estimated daily values for the radiometric gain and offset that might have been applied to TM data. This paper discusses the need for and generation of the NLAPSIC gain and offset tables. A companion paper covers the application of and errors associated with using these tables.","largerWorkTitle":"Proceedings of SPIE - The International Society for Optical Engineering","conferenceTitle":"Earth Observing Systems XIII","conferenceDate":"11 August 2008 through 13 August 2008","conferenceLocation":"San Diego, CA","language":"English","doi":"10.1117/12.795268","issn":"0277786X","isbn":"9780819473011","usgsCitation":"Barsi, J., Chander, G., Micijevic, E., Markham, B.L., and Haque, M., 2008, Development of landsat-5 thematic mapper internal calibrator gain and offset table, in Proceedings of SPIE - The International Society for Optical Engineering, v. 7081, San Diego, CA, 11 August 2008 through 13 August 2008, https://doi.org/10.1117/12.795268.","costCenters":[],"links":[{"id":204903,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1117/12.795268"},{"id":218988,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"7081","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a005ae4b0c8380cd4f6fa","contributors":{"authors":[{"text":"Barsi, J.

This approach focuses on current patterns of organismal and ecosystem-level biodiversity, but typically ignores the evolutionary processes that control the gain and loss of biodiversity at these and other levels (e.g., genetic, ecological). In order to include evolutionary processes in conservation planning efforts, their spatial components must first be identified and mapped. We describe a GIS-based approach for explicitly mapping patterns of genetic divergence and diversity for multiple species (a \"multi-species genetic landscape\"). Using this approach, we analyzed mitochondrial DNA datasets from 21 vertebrate and invertebrate species in southern California to identify areas with common phylogeographic breaks and high intrapopulation diversity. The result is an evolutionary framework for southern California within which patterns of genetic diversity can be analyzed in the context of historical processes, future evolutionary potential and current reserve design. Our multi-species genetic landscapes pinpoint six hotspots where interpopulation genetic divergence is consistently high, five evolutionary hotspots within which genetic connectivity is high, and three hotspots where intrapopulation genetic diversity is high. These 14 hotspots can be grouped into eight geographic areas, of which five largely are unprotected at this time. The multi-species genetic landscape approach may provide an avenue to readily incorporate measures of evolutionary process into GIS-based systematic conservation assessment and land-use planning.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.biocon.2008.04.009","issn":"00063207","usgsCitation":"Vandergast, A.G., Bohonak, A., Hathaway, S., Boys, J., and Fisher, R., 2008, Are hotspots of evolutionary potential adequately protected in southern California?: Biological Conservation, v. 141, no. 6, p. 1648-1664, https://doi.org/10.1016/j.biocon.2008.04.009.","startPage":"1648","endPage":"1664","numberOfPages":"17","costCenters":[],"links":[{"id":214257,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.biocon.2008.04.009"},{"id":241959,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"141","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ed5ce4b0c8380cd49770","contributors":{"authors":[{"text":"Vandergast, Amy G. 0000-0002-7835-6571","orcid":"https://orcid.org/0000-0002-7835-6571","contributorId":57201,"corporation":false,"usgs":true,"family":"Vandergast","given":"Amy","middleInitial":"G.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":442031,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bohonak, A.J.","contributorId":20554,"corporation":false,"usgs":true,"family":"Bohonak","given":"A.J.","affiliations":[],"preferred":false,"id":442027,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hathaway, S.A.","contributorId":56990,"corporation":false,"usgs":true,"family":"Hathaway","given":"S.A.","email":"","affiliations":[],"preferred":false,"id":442030,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Boys, J.","contributorId":44749,"corporation":false,"usgs":true,"family":"Boys","given":"J.","email":"","affiliations":[],"preferred":false,"id":442028,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fisher, Robert N. 0000-0002-2956-3240","orcid":"https://orcid.org/0000-0002-2956-3240","contributorId":51675,"corporation":false,"usgs":true,"family":"Fisher","given":"Robert N.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":442029,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ,{"id":70010009,"text":"70010009 - 2008 - L5 TM radiometric recalibration procedure using the internal calibration trends from the NLAPS trending database","interactions":[],"lastModifiedDate":"2022-05-18T15:31:19.719614","indexId":"70010009","displayToPublicDate":"2008-01-01T00:00:00","publicationYear":"2008","noYear":false,"publicationType":{"id":24,"text":"Conference Paper"},"publicationSubtype":{"id":19,"text":"Conference Paper"},"title":"L5 TM radiometric recalibration procedure using the internal calibration trends from the NLAPS trending database","docAbstract":"From the Landsat program's inception in 1972 to the present, the earth science user community has benefited from a historical record of remotely sensed data. The multispectral data from the Landsat 5 (L5) Thematic Mapper (TM) sensor provide the backbone for this extensive archive. Historically, the radiometric calibration procedure for this imagery used the instrument's response to the Internal Calibrator (IC) on a scene-by-scene basis to determine the gain and offset for each detector. The IC system degraded with time causing radiometric calibration errors up to 20 percent. In May 2003 the National Landsat Archive Production System (NLAPS) was updated to use a gain model rather than the scene acquisition specific IC gains to calibrate TM data processed in the United States. Further modification of the gain model was performed in 2007. L5 TM data that were processed using IC prior to the calibration update do not benefit from the recent calibration revisions. A procedure has been developed to give users the ability to recalibrate their existing Level-1 products. The best recalibration results are obtained if the work order report that was originally included in the standard data product delivery is available. However, many users may not have the original work order report. In such cases, the IC gain look-up table that was generated using the radiometric gain trends recorded in the NLAPS database can be used for recalibration. This paper discusses the procedure to recalibrate L5 TM data when the work order report originally used in processing is not available. A companion paper discusses the generation of the NLAPS IC gain and bias look-up tables required to perform the recalibration.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of SPIE - The International Society for Optical Engineering","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"Earth Observing Systems XIII","conferenceDate":"Aug 11-13, 2008","conferenceLocation":"San Diego, CA","language":"English","publisher":"SPIE","doi":"10.1117/12.795652","usgsCitation":"Chander, G., Haque, M., Micijevic, E., and Barsi, J., 2008, L5 TM radiometric recalibration procedure using the internal calibration trends from the NLAPS trending database, in Proceedings of SPIE - The International Society for Optical Engineering, v. 7081, San Diego, CA, Aug 11-13, 2008, 708114, https://doi.org/10.1117/12.795652.","productDescription":"708114","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":219047,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"7081","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a40d3e4b0c8380cd65088","contributors":{"authors":[{"text":"Chander, G.","contributorId":51449,"corporation":false,"usgs":true,"family":"Chander","given":"G.","affiliations":[],"preferred":false,"id":357664,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Haque, Md.
