These sites and years represented differences in available prey. In Lake Michigan, energy densities of deepwater sculpin in 2001 were similar to those reported in 1969-1971. In contrast, energy content declined at least 26% at Muskegon between 2001 and 2009. Overall, energy density was 31-34% higher at a site with abundant Diporeia spp. compared with two sites without Diporeia spp. Deepwater sculpin diets consisted primarily of M. relicta at all sites, but included 10-17% (dry mass) Diporeia spp. at sites where this crustacean was still abundant. Food biomass in stomachs was higher at sites with abundant Diporeia spp. than at those without Diporeia spp. Deepwater sculpin energy density and food biomass in stomachs were similar between two sites without Diporeia spp. despite differences in abundance of remaining prey, M. relicta. Declines in deepwater sculpin energy density suggest the potential for further effects on other species and changes in the flow of energy through the food web of the Great Lakes. Published 2010.

Untreated and anosmic migrating sea lampreys were implanted with acoustic transmitters and then released outside the Ocqueoc River. Lampreys swam only at night and then actively. When outside of the river plume, lampreys pursued relatively straight bearings parallel to the shoreline while making frequent vertical excursions. In contrast, when within the plume, lampreys made large turns and exhibited a weak bias towards the river mouth, which one-third of them entered. The behavior of anosmic lampreys resembled that of untreated lampreys outside of the plume, except they pursued a more northerly compass bearing. To locate streams, sea lampreys appear to employ a three-phase odor-mediated strategy that involves an initial search along shorelines while casting vertically, followed by river-water-induced turning that brings them close to the river's mouth, which they then enter using rheotaxis. This novel strategy differs from that of salmonids and appears to offer this poor swimmer adaptive flexibility and suggests ways that pheromonal odors might be used to manage this invasive species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Fisheries and Aquatic Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/F10-169","issn":"0706652X","usgsCitation":"Vrieze, L., Bergstedt, R., and Sorensen, P., 2011, Olfactory-mediated stream-finding behavior of migratory adult sea lamprey (Petromyzon marinus): Canadian Journal of Fisheries and Aquatic Sciences, v. 68, no. 3, p. 523-533, https://doi.org/10.1139/F10-169.","startPage":"523","endPage":"533","numberOfPages":"11","costCenters":[],"links":[{"id":244305,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216435,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/F10-169"}],"volume":"68","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6d5ee4b0c8380cd750d5","contributors":{"authors":[{"text":"Vrieze, L.A.","contributorId":67706,"corporation":false,"usgs":true,"family":"Vrieze","given":"L.A.","email":"","affiliations":[],"preferred":false,"id":452531,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bergstedt, R.A.","contributorId":74330,"corporation":false,"usgs":true,"family":"Bergstedt","given":"R.A.","email":"","affiliations":[],"preferred":false,"id":452532,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sorensen, P.W.","contributorId":66884,"corporation":false,"usgs":true,"family":"Sorensen","given":"P.W.","email":"","affiliations":[],"preferred":false,"id":452530,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Although area burned is often used to summarize a fire season, burned area may not be well correlated with either the number or ecological effect of fires. Using the Landsat data archive, we examined all 148 wildland fires (prescribed fires and wildfires) &gt;40 ha from 1984 through 2009 for the portion of the Sierra Nevada centered on Yosemite National Park, California, USA. We calculated mean fire frequency and mean annual area burned from a combination of field- and satellite-derived data. We used the continuous probability distribution of the differenced Normalized Burn Ratio (dNBR) values to describe fire severity. For fires &gt;40 ha, fire frequency, annual area burned, and cumulative severity were consistent in only 13 of 26 years (50 %), but all pair-wise comparisons among these fire regime attributes were significant. Borrowing from long-established practice in climate science, we defined “fire normals” to be the 26 year means of fire frequency, annual area burned, and the area under the cumulative probability distribution of dNBR. Fire severity normals were significantly lower when they were aggregated by year compared to aggregation by area.

In North America IHNV has three major genogroups designated U, M, and L. Host-specificity of the M and U genogroups of IHNV has been established both in the field and in experimental challenges, with M isolates being more prevalent and more virulent in rainbow trout (Oncorhynchus mykiss), and U isolates being more prevalent and highly virulent in sockeye salmon (Oncorhynchus nerka). In this study, efficacy of DNA vaccines containing either M (pM) or U (pU) virus glycoprotein genes was investigated during intra- and cross-genogroup challenges in rainbow trout. In virus challenges at 7 days post-vaccination (early antiviral response), both pM and pU were highly protective against either M or U IHNV. In challenges at 28 days post-vaccination (specific antiviral response), both pM and pU were protective against M IHNV but the homologous pM vaccine was significantly more protective than pU in one of two experiments. At this stage both pM and pU induced comparably high protection against U IHNV challenge. Correlates of protection were also investigated by assessing the expression of the interferon-stimulated gene Mx-1 and the production of neutralizing antibodies (NAbs) following pM or pU DNA vaccination. Mx-1 gene expression, measured at 4 and 7 days post-vaccination as an indicator of the host innate immune response, was found to be significantly higher after pM than pU vaccination in some cases. Neutralizing antibody was produced in response to the two vaccines, but antibody titers did not show consistent correlation with protection. The results show that the rainbow trout innate and adaptive immune responses have some ability to distinguish between the U and M genogroup IHNV, but overall the pM and pU vaccines were protective against both homologous and cross-genogroup challenges.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Fish and Shellfish Immunology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.fsi.2011.03.003","issn":"10504648","usgsCitation":"Penaranda, M., LaPatra, S., and Kurath, G., 2011, Specificity of DNA vaccines against the U and M genogroups of infectious hematopoietic necrosis virus (IHNV) in rainbow trout (Oncorhynchus mykiss): Fish and Shellfish Immunology, v. 31, no. 1, p. 43-51, https://doi.org/10.1016/j.fsi.2011.03.003.","startPage":"43","endPage":"51","numberOfPages":"9","costCenters":[],"links":[{"id":218570,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.fsi.2011.03.003"},{"id":246593,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b952ae4b08c986b31ad97","contributors":{"authors":[{"text":"Penaranda, M.M.D.","contributorId":17845,"corporation":false,"usgs":true,"family":"Penaranda","given":"M.M.D.","email":"","affiliations":[],"preferred":false,"id":454465,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"LaPatra, S.

This shallow, low-pressure deposit has high porosities (ϕ&nbsp;=&nbsp;0.4), high intrinsic permeabilities (<i>k</i>&nbsp;= 10<sup>−12</sup>&nbsp;m<sup>2</sup>) and high hydrate saturations (<i>S</i><sub>H</sub>&nbsp;=&nbsp;0.65). It has a low temperature (<i>T</i>&nbsp;=&nbsp;2.3–2.6&nbsp;°C) because of its proximity to the overlying permafrost. The simulation results indicate that vertical wells operating at a constant bottomhole pressure would produce at very low rates for a very long period. Horizontal wells increase gas production by almost two orders of magnitude, but production remains low. Sensitivity analysis indicates that the initial deposit temperature is by the far the most important factor determining production performance (and the most effective criterion for target selection) because it controls the sensible heat available to fuel dissociation. Thus, a 1&nbsp;°C increase in temperature is sufficient to increase the production rate by a factor of almost 8. Production also increases with a decreasing hydrate saturation (because of a larger effective permeability for a given<span>&nbsp;</span><i>k</i>), and is favored (to a lesser extent) by anisotropy.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/j.marpetgeo.2010.01.005","issn":"02648172","usgsCitation":"Moridis, G.J., Silpngarmlert, S., Reagan, M.T., Collett, T.S., and Zhang, K., 2011, Gas production from a cold, stratigraphically-bounded gas hydrate deposit at the Mount Elbert Gas Hydrate Stratigraphic Test Well, Alaska North Slope: Implications of uncertainties: Marine and Petroleum Geology, v. 28, no. 2, p. 517-534, https://doi.org/10.1016/j.marpetgeo.2010.01.005.","productDescription":"18 p.","startPage":"517","endPage":"534","numberOfPages":"18","costCenters":[],"links":[{"id":246355,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218355,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.marpetgeo.2010.01.005"}],"country":"United States","state":"Alaska","otherGeospatial":"North Slope","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -167.87109375,\n              67.47492238478702\n            ],\n            [\n              -141.064453125,\n              67.47492238478702\n            ],\n            [\n              -141.064453125,\n              71.41317683396566\n            ],\n            [\n              -167.87109375,\n              71.41317683396566\n            ],\n            [\n              -167.87109375,\n              67.47492238478702\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"28","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a14d6e4b0c8380cd54bbd","contributors":{"authors":[{"text":"Moridis, G.

This paper reviews several key advancements in both technology and science in the field of currents in submarine canyons since the1979 publication of <i>Currents in Submarine Canyons and Other Sea Valleys by</i> Francis Shepard and colleagues. Precise placements of high-resolution, high-frequency instruments have not only allowed researchers to collect new data that are essential for advancing and generalizing theories governing the canyon currents, but have also revealed new natural phenomena that challenge the understandings of the theorists and experimenters in their predictions of submarine canyon flow fields. Baroclinic motions at tidal frequencies, found to be intensified both up canyon and toward the canyon floor, dominate the flow field and control the sediment transport processes in submarine canyons. Turbidity currents are found to frequently occur in active submarine canyons such as Monterey Canyon. These turbidity currents have maximum speeds of nearly 200 cm/s, much smaller than the speeds of turbidity currents in geological time, but still very destructive. In addition to traditional Eulerian measurements, Lagrangian flow data are essential in quantifying water and sediment transport in submarine canyons. A concerted experiment with multiple monitoring stations along the canyon axis and on nearby shelves is required to characterize the storm-trigger mechanism for turbidity currents.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/GES00640.1","issn":"1553040X","usgsCitation":"Xu, J.P., 2011, Measuring currents in submarine canyons: technological and scientific progress in the past 30 years: Geosphere, v. 7, no. 4, p. 868-876, https://doi.org/10.1130/GES00640.1.","productDescription":"9 p.","startPage":"868","endPage":"876","numberOfPages":"9","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-025043","costCenters":[],"links":[{"id":475331,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1130/ges00640.1","text":"Publisher Index Page"},{"id":246275,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218278,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/GES00640.1"}],"volume":"7","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5346e4b0c8380cd6c981","contributors":{"authors":[{"text":"Xu, J.

For the six events studied, mean emission rates for eruptions were ~13,000 t/d CO<sub>2</sub> and 5200 t/d SO<sub>2</sub>, but only ~1200 t/d CO<sub>2</sub> and 500 t/d SO<sub>2</sub> for non-eruptive events (‘failed eruptions’). Statistical analysis suggests degassing thresholds for eruption on the order of 1500 and 1000 t/d for CO<sub>2</sub> and SO<sub>2</sub>, respectively. Emission rates greater than 4000 and 2000 t/d for CO<sub>2</sub> and SO<sub>2</sub>, respectively, almost exclusively resulted during eruptive events (the only exception being two measurements at Fourpeaked). While this analysis could suggest that unerupted magmas have lower pre-eruptive volatile contents, we favor the explanations that either the amount of magma feeding actual eruptions is larger than that driving failed eruptions, or that magmas from failed eruptions experience less decompression such that the majority of H<sub>2</sub>O remains dissolved and thus insufficient permeability is produced to release the trapped volatile phase (or both). In the majority of unrest and eruption sequences, increases in CO<sub>2</sub> emission relative to SO<sub>2</sub> emission were observed early in the sequence. With time, all events converged to a common molar value of C/S between 0.5 and 2. These geochemical trends argue for roughly similar decompression histories until shallow levels are reached beneath the edifice (i.e., from 20–35 to ~4–6 km) and perhaps roughly similar initial volatile contents in all cases. Early elevated CO<sub>2</sub> levels that we find at these high-latitude, andesitic arc volcanoes have also been observed at mid-latitude, relatively snow-free, basaltic volcanoes such as Stromboli and Etna. Typically such patterns are attributed to injection and decompression of deep (CO<sub>2</sub>-rich) magma into a shallower chamber and open system degassing prior to eruption. Here we argue that the C/S trends probably represent tapping of vapor-saturated regions with high C/S, and then gradual degassing of remaining dissolved volatiles as the magma progresses toward the surface. At these volcanoes, however, C/S is often accentuated due to early preferential scrubbing of sulfur gases. The range of equilibrium degassing is consistent with the bulk degassing of a magma with initial CO<sub>2</sub> and S of 0.6 and 0.2 wt.%, respectively, similar to what has been suggested for primitive Redoubt magmas.","language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s00445-011-0453-4","issn":"02588900","usgsCitation":"Werner, C., Doukas, M., and Kelly, P., 2011, Gas emissions from failed and actual eruptions from Cook Inlet Volcanoes, Alaska, 1989-2006: Bulletin of Volcanology, v. 73, no. 2, p. 155-173, https://doi.org/10.1007/s00445-011-0453-4.","productDescription":"19 p.","startPage":"155","endPage":"173","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":246328,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218329,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00445-011-0453-4"}],"country":"United States","state":"Alaska","otherGeospatial":"Cook Inlet","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -154.171142578125,\n              58.53959476664049\n            ],\n            [\n              -154.171142578125,\n              61.6794500443896\n            ],\n            [\n              -148.787841796875,\n              61.6794500443896\n            ],\n            [\n              -148.787841796875,\n              58.53959476664049\n            ],\n            [\n              -154.171142578125,\n              58.53959476664049\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"73","issue":"2","noUsgsAuthors":false,"publicationDate":"2011-02-27","publicationStatus":"PW","scienceBaseUri":"505a14c9e4b0c8380cd54b73","contributors":{"authors":[{"text":"Werner, C.A.","contributorId":50734,"corporation":false,"usgs":true,"family":"Werner","given":"C.A.","email":"","affiliations":[],"preferred":false,"id":454214,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Doukas, M.P.","contributorId":28615,"corporation":false,"usgs":true,"family":"Doukas","given":"M.P.","email":"","affiliations":[],"preferred":false,"id":454213,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kelly, P.J.","contributorId":65312,"corporation":false,"usgs":true,"family":"Kelly","given":"P.J.","email":"","affiliations":[],"preferred":false,"id":454215,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Algal fluorescence, dissolved oxygen, temperature, pH, conductivity, and turbidity were measured every 30min. Grab samples were collected every 2h for water quality analyses, including nutrients, suspended sediment, and chlorophyll/pheophytin. Strong diel patterns were observed for dissolved oxygen, pH, and temperature within the parcel of water. In contrast, algal pigments and nitrate did not exhibit diel patterns within the parcel of water, but did exhibit strong diel patterns for samples collected at a fixed sampling location. The diel patterns observed at fixed sampling locations for these constituents can be attributed to algal growth during the day and downstream transport (washout) of algae at night. Algal pigments showed a rapid daytime increase during the first 48h followed by a general decrease for the remainder of the study, possibly due to sedimentation and photobleaching.

Biogeochemical responses to this enrichment include changes in the availability of key limiting nutrients such as P, the potential for increased turnover of nutrient pools due to accelerated plant decomposition, and increased rates of mercury methylation associated with sulfate enrichment. Mineral enrichment has also been linked to the loss of sensitive macrophyte species, although dominant Everglades species appear tolerant of a broad range of mineral chemistry. Shifts in periphyton community composition and function provide an especially sensitive indicator of mineral enrichment.

This paper provides an overview of key discoveries between sols 511 and 2300, complementing earlier papers covering results from the initial phases of the mission. Key new results include (1) atmospheric argon measurements that demonstrate the importance of atmospheric transport to and from the winter carbon dioxide polar ice caps; (2) observations showing that aeolian ripples covering the plains were generated by easterly winds during an epoch with enhanced Hadley cell circulation; (3) the discovery and characterization of cobbles and boulders that include iron and stony-iron meteorites and Martian impact ejecta; (4) measurements of wall rock strata within Erebus and Victoria craters that provide compelling evidence of formation by aeolian sand deposition, with local reworking within ephemeral lakes; (5) determination that the stratigraphy exposed in the walls of Victoria and Endurance craters show an enrichment of chlorine and depletion of magnesium and sulfur with increasing depth. This result implies that regional-scale aqueous alteration took place before formation of these craters. Most recently, Opportunity has been traversing toward the ancient Endeavour crater. Orbital data show that clay minerals are exposed on its rim. Hydrated sulfate minerals are exposed in plains rocks adjacent to the rim, unlike the surfaces of plains outcrops observed thus far by Opportunity. With continued mechanical health, Opportunity will reach terrains on and around Endeavour's rim that will be markedly different from anything examined to date.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research E: Planets","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","doi":"10.1029/2010JE003746","issn":"01480227","usgsCitation":"Arvidson, R., Ashley, J.W., Bell, J., Chojnacki, M., Cohen, J., Economou, T., Farrand, W.H., Fergason, R.L., Fleischer, I., Geissler, P.E., Gellert, R., Golombek, M., Grotzinger, J., Guinness, E., Haberle, R., Herkenhoff, K.E., Herman, J., Iagnemma, K., Jolliff, B., Johnson, J.R., Klingelhofer, G., Knoll, A., Knudson, A., Li, R., McLennan, S.M., Mittlefehldt, D.W., Morris, R., Parker, T.J., Rice, M., Schroder, C., Soderblom, L.A., Squyres, S.W., Sullivan, R., and Wolff, M., 2011, Opportunity Mars Rover mission: Overview and selected results from Purgatory ripple to traverses to Endeavour crater: Journal of Geophysical Research E: Planets, v. 116, no. 2, https://doi.org/10.1029/2010JE003746.","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":475435,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2010je003746","text":"Publisher Index Page"},{"id":246359,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Mars","volume":"116","issue":"2","noUsgsAuthors":false,"publicationDate":"2011-02-08","publicationStatus":"PW","scienceBaseUri":"505a6ec2e4b0c8380cd757b3","contributors":{"authors":[{"text":"Arvidson, R.

At the time, Fourpeaked was an unmonitored volcano with no known Holocene activity, based on limited field work. Airborne gas sampling began within days of the eruption and a modest seismic network was installed in stages. Vigorous steaming continued for months; however, there were no further eruptions similar in scale to the September 17 event. This eruption was followed by several months of sustained seismicity punctuated by vigorous swarms, and SO<sub>2</sub> emissions exceeding a thousand tons/day. Based on observations during and after the phreatic eruption, and assuming no recent pre-historical eruptive activity at Fourpeaked, we propose that the activity was caused by a minor injection of new magma at or near 5km depth beneath Fourpeaked, which remained active over several months as this magma equilibrated into the crust. By early 2007 declining seismicity and SO<sub>2</sub> emission signaled the end of unrest. Because the Fourpeaked seismic network was installed in stages and the seismicity was punctuated by discrete swarms, we use Fourpeaked to illustrate quantitatively the efficacy and shortcomings of rapid response seismic networks for tracking volcanic earthquakes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Volcanology and Geothermal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.jvolgeores.2010.11.018","issn":"03770273","usgsCitation":"Gardine, M., West, M., Werner, C., and Doukas, M., 2011, Evidence of magma intrusion at Fourpeaked volcano, Alaska in 2006-2007 from a rapid-response seismic network and volcanic gases: Journal of Volcanology and Geothermal Research, v. 200, no. 3-4, p. 192-200, https://doi.org/10.1016/j.jvolgeores.2010.11.018.","productDescription":"9 p.","startPage":"192","endPage":"200","numberOfPages":"9","temporalStart":"2006-09-17","temporalEnd":"2007-12-31","costCenters":[{"id":157,"text":"Cascades Volcano Observatory","active":false,"usgs":true}],"links":[{"id":216328,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jvolgeores.2010.11.018"},{"id":244191,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Fourpeaked Mountain","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -153.652746,58.763376 ], [ -153.652746,58.78338 ], [ -153.632731,58.78338 ], [ -153.632731,58.763376 ], [ -153.652746,58.763376 ] ] ] } } ] }","volume":"200","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0d65e4b0c8380cd52fc0","contributors":{"authors":[{"text":"Gardine, M.","contributorId":88972,"corporation":false,"usgs":true,"family":"Gardine","given":"M.","email":"","affiliations":[],"preferred":false,"id":453287,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"West, M.","contributorId":54729,"corporation":false,"usgs":true,"family":"West","given":"M.","email":"","affiliations":[],"preferred":false,"id":453284,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Werner, C.","contributorId":72917,"corporation":false,"usgs":true,"family":"Werner","given":"C.","email":"","affiliations":[],"preferred":false,"id":453286,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Doukas, M.","contributorId":68900,"corporation":false,"usgs":true,"family":"Doukas","given":"M.","email":"","affiliations":[],"preferred":false,"id":453285,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Musson and M.J. Jimenez) have been proposed for estimating an earthquake location and magnitude from intensity data alone. The locations and magnitudes obtained for a given set of intensity data are almost always different, and no one technique is consistently best at matching instrumental locations and magnitudes of recent well-recorded earthquakes in Italy. Rather than attempting to select one of the three solutions as best, we use all three techniques to estimate the location and the magnitude and the epistemic uncertainties among them. The estimates are calculated using bootstrap resampled data sets with Monte Carlo sampling of a decision tree. The decision-tree branch weights are based on goodness-of-fit measures of location and magnitude for recent earthquakes. The location estimates are based on the spatial distribution of locations calculated from the bootstrap resampled data. The preferred source location is the locus of the maximum bootstrap location spatial density. The location uncertainty is obtained from contours of the bootstrap spatial density: 68% of the bootstrap locations are within the 68% confidence region, and so on. For large earthquakes, our preferred location is not associated with the epicenter but with a location on the extended rupture surface. For small earthquakes, the epicenters are generally consistent with the location uncertainties inferred from the intensity data if an epicenter inaccuracy of 2-3 km is allowed. The preferred magnitude is the median of the distribution of bootstrap magnitudes. As with location uncertainties, the uncertainties in magnitude are obtained from the distribution of bootstrap magnitudes: the bounds of the 68% uncertainty range enclose 68% of the bootstrap magnitudes, and so on. The instrumental magnitudes for large and small earthquakes are generally consistent with the confidence intervals inferred from the distribution of bootstrap resampled magnitudes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Seismological Society of America","publisherLocation":"El Cerrito, CA","doi":"10.1785/0120110118","issn":"00371106","usgsCitation":"Bakun, W.H., Gomez, C.A., and Stucchi, M., 2011, Epistemic uncertainty in the location and magnitude of earthquakes in Italy from Macroseismic data: Bulletin of the Seismological Society of America, v. 101, no. 6, p. 2712-2725, https://doi.org/10.1785/0120110118.","productDescription":"14 p.","startPage":"2712","endPage":"2725","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":216041,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120110118"},{"id":243880,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Italy","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 6.63,35.29 ], [ 6.63,47.09 ], [ 18.78,47.09 ], [ 18.78,35.29 ], [ 6.63,35.29 ] ] ] } } ] }","volume":"101","issue":"6","noUsgsAuthors":false,"publicationDate":"2011-12-08","publicationStatus":"PW","scienceBaseUri":"505a0a16e4b0c8380cd521cd","contributors":{"authors":[{"text":"Bakun, W.

The calculated moment tensors indicate the presence of a volumetric source mechanism. Systematic reconstruction of the source mechanism shows the source consists of a sill intersected by either a sub-vertical east-west trending dike or a sub-vertical pipe and a weak single force. The trend of the dike may be controlled by the east-west trending Augustine-Seldovia arch. The data from the network of broadband sensors is limited to fourteen seismic traces, and synthetic modeling confirms the ability of the network to recover the source mechanism. The synthetic modeling also provides a guide to the expected capability of a broadband network to resolve very-long-period source mechanisms, particularly when confronted with limited observational data.

Our analysis is primarily based on the 15 SAR scenes acquired during arctic growing seasons. The Radarsat-1 intensity data are used to map the onset and progression of the fire, and interferometric coherence images are used to qualify burn severity and monitor post-fire recovery. We base our analysis of the fire on three test sites, two from within the fire and one unburned site. The B346 fire increased backscattered intensity values for the two burn study sites by approximately 5–6 dB and substantially reduced coherence from background levels of approximately 0.8 in unburned background forested areas to approximately 0.2 in the burned area. Using ancillary vegetation information from the National Land Cover Database (NLCD) and information on burn severity from Normalized Burn Ratio (NBR) data, we conclude that burn site 2 was more severely burned than burn site 1 and that C-band interferometric coherence data are useful for mapping landscape changes due to fire. Differences in burn severity and topography are determined to be the likely reasons for the observed differences in post-fire intensity and coherence trends between burn sites.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/19475705.2010.532971","issn":"19475705","usgsCitation":"Rykhus, R.P., and Lu, Z., 2011, Monitoring a boreal wildfire using multi-temporal Radarsat-1 intensity and coherence images: Geomatics, Natural Hazards and Risk, v. 2, no. 1, p. 15-32, https://doi.org/10.1080/19475705.2010.532971.","productDescription":"18 p.","startPage":"15","endPage":"32","numberOfPages":"18","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":244157,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216294,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/19475705.2010.532971"}],"volume":"2","issue":"1","noUsgsAuthors":false,"publicationDate":"2011-03-14","publicationStatus":"PW","scienceBaseUri":"505a5d7fe4b0c8380cd703e3","contributors":{"authors":[{"text":"Rykhus, Russell P.","contributorId":27337,"corporation":false,"usgs":true,"family":"Rykhus","given":"Russell","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":453282,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lu, Zhong 0000-0001-9181-1818 lu@usgs.gov","orcid":"https://orcid.org/0000-0001-9181-1818","contributorId":901,"corporation":false,"usgs":true,"family":"Lu","given":"Zhong","email":"lu@usgs.gov","affiliations":[],"preferred":true,"id":453283,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Three separate efforts at Hole 949C yielded permeability estimates for the d&eacute;collement spanning four orders of magnitude. An analysis of problems encountered during installation of the casing and seals provides insights into how the borehole conditions may have led to the wide range of results. During the installation, sediments from the surrounding formation repeatedly intruded into the borehole and casing. Stress analysis shows that the weak sediments were deforming plastically and the radial and tangential stresses around the borehole were significantly lower than lithostatic. This perturbed stress state may explain why the test pressure records showed indications of hydrofracture at pressures below lithostatic, and permeabilities rose rapidly as the estimated effective stress dropped below 0.8&nbsp;MPa. Even after the borehole was sealed, the plastic deformation of the formation and relatively large gap of the wire wrapped screen allowed sediment to flow into the casing. Force equilibrium calculations predict sediment would have filled the borehole to 10&nbsp;cm above the top of the screen by the time slug tests were conducted 1.5&nbsp;years after the borehole was sealed. Reanalysis of the slug test results with these conditions yields several orders of magnitude higher permeability estimates than the original analysis which assumed an open casing.

Murrelets that spent more nights attending congregations were located closer to the island during the day, so regular attendance at the congregations may have constrained daytime traveling distances to foraging locations. In mid-May 2003 home-range sizes increased while congregation attendance decreased, likely indicating the end of colony attendance and declining availability of prey near Anacapa Island. In both years, incubating murrelets foraged farther from the colony than did nonbreeding murrelets, suggesting that breeding and nonbreeding murrelets use different foraging strategies to meet their energetic requirements.</span></p>","language":"English","publisher":"Oxford Academic","doi":"10.1525/cond.2011.100040","issn":"00105422","usgsCitation":"Hamilton, C., Golightly, R., and Takekawa, J.Y., 2011, Relationships between breeding status, social -congregation attendance, and foraging distance of Xantus's Murrelets: Condor, v. 113, no. 1, p. 140-149, https://doi.org/10.1525/cond.2011.100040.","productDescription":"10 p.","startPage":"140","endPage":"149","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":475535,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1525/cond.2011.100040","text":"Publisher Index Page"},{"id":244124,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Channel Islands","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.44287109374999,\n              31.70947636001935\n            ],\n            [\n              -116.69677734375,\n              31.70947636001935\n            ],\n            [\n              -116.69677734375,\n              34.65128519895413\n            ],\n            [\n              -121.44287109374999,\n              34.65128519895413\n            ],\n            [\n              -121.44287109374999,\n              31.70947636001935\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"113","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a79ae4b0e8fec6cdc504","contributors":{"authors":[{"text":"Hamilton, C.D.","contributorId":21757,"corporation":false,"usgs":true,"family":"Hamilton","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":453275,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Golightly, R.T.","contributorId":10743,"corporation":false,"usgs":true,"family":"Golightly","given":"R.T.","email":"","affiliations":[],"preferred":false,"id":453274,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Takekawa, John Y. 0000-0003-0217-5907 john_takekawa@usgs.gov","orcid":"https://orcid.org/0000-0003-0217-5907","contributorId":176168,"corporation":false,"usgs":true,"family":"Takekawa","given":"John","email":"john_takekawa@usgs.gov","middleInitial":"Y.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":453276,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
