Using bispectrum cross-correlation, a multiplet of 25 earthquakes is identified spanning five years leading up to the eruption, each event having first motions compatible with a normal fault striking NE–SW. Cross-correlation differential times are used to relocate earthquakes occurring between January 2003 and February 2009. The bulk of the seismicity prior to the onset of the eruption on 12 July 2008 occurred southwest of the caldera beneath a geothermal field. Earthquakes associated with the onset of the eruption occurred beneath the northern portion of the caldera and started as deep as 13 km. Subsequent earthquakes occurred predominantly at 3 km depth, coinciding with the depth at which the magma body has been modeled using geodetic data. Automated SWS analysis of the Okmok catalog reveals radial polarization outside the caldera and a northwest-southeast polarization within. We interpret these polarizations in terms of a magma reservoir near the center of the caldera, which we model with a Mogi point source. SWS analysis using the same input processing parameters for each event in the multiplet reveals no temporal changes in anisotropy over the duration of the multiplet, suggesting either a short-term or small increase in stress just before the eruption that was not detected by GPS, or eruption triggering by a mechanism other than a change of stress in the system.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.","doi":"10.1029/2009JB006991","usgsCitation":"Johnson, J.H., Prejean, S., Savage, M.K., and Townend, J., 2010, Anisotropy, repeating earthquakes, and seismicity associated with the 2008 eruption of Okmok Volcano, Alaska: Journal of Geophysical Research, v. 115, B00B04; 21 p., https://doi.org/10.1029/2009JB006991.","productDescription":"B00B04; 21 p.","ipdsId":"IP-021090","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":475525,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2009jb006991","text":"Publisher Index Page"},{"id":263640,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2009JB006991"},{"id":263641,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Okmok Volcano","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 172.5,51.2 ], [ 172.5,71.4 ], [ 130.0,71.4 ], [ 130.0,51.2 ], [ 172.5,51.2 ] ] ] } } ] }","volume":"115","noUsgsAuthors":false,"publicationDate":"2010-09-11","publicationStatus":"PW","scienceBaseUri":"50bdd7fae4b0f63017347684","contributors":{"authors":[{"text":"Johnson, Jessica H. jessjohnson@usgs.gov","contributorId":3523,"corporation":false,"usgs":true,"family":"Johnson","given":"Jessica","email":"jessjohnson@usgs.gov","middleInitial":"H.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":469569,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Prejean, Stephanie","contributorId":61916,"corporation":false,"usgs":true,"family":"Prejean","given":"Stephanie","affiliations":[],"preferred":false,"id":469570,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Savage, Martha K.","contributorId":82199,"corporation":false,"usgs":true,"family":"Savage","given":"Martha","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":469571,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Townend, John","contributorId":94568,"corporation":false,"usgs":true,"family":"Townend","given":"John","affiliations":[],"preferred":false,"id":469572,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

We address this question using numerical simulations of ruptures on a planar, vertical strike-slip fault embedded in a three-dimensional, homogeneous, linear elastic half-space. Ruptures propagate spontaneously in accordance with a linear slip-weakening friction law through both homogeneous and heterogeneous initial shear stress fields. In the 3-D homogeneous case, rupture fronts are curved owing to interactions with the free surface and the finite fault width; however, this curvature does not greatly diminish the coherence of Mach fronts relative to cases in which the rupture front is constrained to be straight, as studied by Dunham and Bhat (2008a). Introducing heterogeneity in the initial shear stress distribution causes ruptures to propagate at speeds that locally fluctuate above and below the shear wave speed. Calculations of the Fourier amplitude spectra (FAS) of ground velocity time histories corroborate the kinematic results of Bizzarri and Spudich (2008a): (1) The ground motion of a supershear rupture is richer in high frequency with respect to a subshear one. (2) When a Mach pulse is present, its high frequency content overwhelms that arising from stress heterogeneity. Present numerical experiments indicate that a Mach pulse causes approximately an <i>ω</i><sup>−1.7</sup> high frequency falloff in the FAS of ground displacement. Moreover, within the context of the employed representation of heterogeneities and over the range of parameter space that is accessible with current computational resources, our simulations suggest that while heterogeneities reduce peak ground velocity and diminish the coherence of the Mach fronts, ground motion at stations experiencing Mach pulses should be richer in high frequencies compared to stations without Mach pulses. In contrast to the foregoing theoretical results, we find no average elevation of 5%-damped absolute response spectral accelerations (SA) in the period band 0.05–0.4 s observed at stations that presumably experienced Mach pulses during the 1979 Imperial Valley, 1999 Kocaeli, and 2002 Denali Fault earthquakes compared to SA observed at non-Mach pulse stations in the same earthquakes. A 20% amplification of short period SA is seen only at a few of the Imperial Valley stations closest to the fault. This lack of elevated SA suggests that either Mach pulses in real earthquakes are even more incoherent that in our simulations or that Mach pulses are vulnerable to attenuation through nonlinear soil response. In any case, this result might imply that current engineering models of high frequency earthquake ground motions do not need to be modified by more than 20% close to the fault to account for Mach pulses, provided that the existing data are adequately representative of ground motions from supershear earthquakes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research B: Solid Earth","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.","doi":"10.1029/2009JB006819","usgsCitation":"Bizzarri, A., Dunham, E.M., and Spudich, P., 2010, Coherence of Mach fronts during heterogeneous supershear earthquake rupture propagation: Simulations and comparison with observations: Journal of Geophysical Research B: Solid Earth, v. 115, no.

Here we investigate the density structure of the North American (NA) upper mantle based on the integrative use of the gravity field and seismic data. The basis of our study is the removal of the gravitational effect of the crust to determine the mantle gravity anomalies. The effect of the crust is removed in three steps by subtracting the gravitational contributions of (1) topography and bathymetry, (2) low-density sedimentary accumulations, and (3) the three-dimensional density structure of the crystalline crust as determined by seismic observations. Information regarding sedimentary accumulations, including thickness and density, are taken from published maps and summaries of borehole measurements of densities; the seismic structure of the crust is based on a recent compilation, with layer densities estimated from P-wave velocities. The resultant mantle gravity anomaly map shows a pronounced negative anomaly (−50 to −400 mGal) beneath western North America and the adjacent oceanic region and positive anomalies (+50 to +350 mGal) east of the NA Cordillera. This pattern reflects the well-known division of North America into the stable eastern region and the tectonically active western region. The close correlation of large-scale features of the mantle anomaly map with those of the topographic map indicates that a significant amount of the topographic uplift in western NA is due to buoyancy in the hot upper mantle, a conclusion supported by previous investigations. To separate the contributions of mantle temperature anomalies from mantle compositional anomalies, we apply an additional correction to the mantle anomaly map for the thermal structure of the uppermost mantle. The thermal model is based on the conversion of seismic shear-wave velocities to temperature and is consistent with mantle temperatures that are independently estimated from heat flow and heat production data. The thermally corrected mantle density map reveals density anomalies that are chiefly due to compositional variations. These compositional density anomalies cause gravitational anomalies that reach ~250 mGal. A pronounced negative anomaly (−50 to −200 mGal) is found over the Canadian shield, which is consistent with chemical depletion and a corresponding low density of the lithospheric mantle, also referred to as the mantle tectosphere. The strongest positive anomaly is coincident with the Gulf of Mexico and indicates a positive density anomaly in the upper mantle, possibly an eclogite layer that has caused subsidence in the Gulf. Two linear positive anomalies are also seen south of 40°N: one with a NE-SW trend in the eastern United States, roughly coincident with the Grenville-Appalachians, and a second with a NW-SE trend beneath the states of Texas, New Mexico, and Colorado. These anomalies are interpreted as being due to (1) the presence of remnants of an oceanic slab in the upper mantle beneath the Grenville-Appalachian suture and (2) mantle thickening caused by a period of shallow, flat subduction during the Laramie orogeny, respectively. Based on these geophysical results, the evolution of the NA upper mantle is depicted in a series of maps and cartoons that display the primary processes that have formed and modified the NA crust and lithospheric upper mantle.","largerWorkTitle":"","language":"English","publisher":"American Geophysical Union","publisherLocation":"","doi":"10.1029/2010JB000866","usgsCitation":"Mooney, W.D., and Kaban, M.K., 2010, The North American upper mantle: Density, composition, and evolution: Journal of Geophysical Research B: Solid Earth, v. 115, no.

The islands are located in the eastern Pacific Ocean within 1.4° of latitude from the equator and range in age from historically erupted to 3 Ma, mostly determined by published K-Ar and 3He isotopic dating. The number of sites collected on each island ranges from 1 to 28, for a total of 186. After combining duplicate site mean directions, 149 are used for an overall mean direction and 8 represent excursions and one reversal path. Divided by geomagnetic polarity chron, 110 site means are Brunhes or Jaramillo (normal polarity), 27 are Matuyama (reversed polarity), and 12 are Gauss (both polarities). We have completed the magnetic cleaning that was commenced in the late 1960s. Secondary (mostly viscous) magnetizations were nearly all removed by alternating field demagnetization at 10 mT. We have used the so-called blanket cleaning method, generally at 10 mT. All sites were in basalt flows and gave good paleomagnetic results; none was rejected in toto, and only a few core specimens were magnetically unsatisfactory. Nearly all sites had eight independently oriented cores, and within-site angular standard deviations of directions range from 1° to 8°. We used both Fisher and Bingham statistics to analyze the data and found that many of the direction populations are strongly elongate along the paleomagnetic meridian, while the corresponding virtual pole (VGP) populations are essentially circularly distributed. The paleomagnetic poles, calculated as the means of VGPs, are as follows: Brunhes and Jaramillo, north latitude = 86.9°, east longitude = 245.1°, and 95% confidence radius A<sub>95</sub> = 1.9°; Matuyama, latitude = 87.2°, longitude = 158.2°, and A<sub>95</sub> = 3.8°; Gauss, latitude = 83.0°, longitude = 204.7°, and A<sub>95</sub> = 7.0°. These paleomagnetic poles do not differ significantly from one another, but the Brunhes and Jaramillo combined pole is significantly near-sided with respect to the Galapagos, as is the overall mean pole, which is at latitude = 87.1° and longitude = 227.6°, with A<sub>95</sub> = 1.7°. Omitting the excursion and reversal path data, the overall angular standard deviation of VGPs is 11.7° with lower and upper 95% confidence limits of 10.8° and 12.7°, respectively, in good agreement with previously published values for near-equatorial sampling latitudes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochemistry, Geophysics, Geosystems","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.","doi":"10.1029/2010GC003090","usgsCitation":"Gromme, S., Mankinen, E.A., and Prevot, M., 2010, Time-averaged paleomagnetic field at the equator: Complete data and results from the Galapagos Islands, Ecuador: Geochemistry, Geophysics, Geosystems, v. 11, 41 p.; Q11009, https://doi.org/10.1029/2010GC003090.","productDescription":"41 p.; Q11009","ipdsId":"IP-019050","costCenters":[{"id":309,"text":"Geology and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":475526,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2010gc003090","text":"Publisher Index Page"},{"id":263911,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":263910,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2010GC003090"}],"country":"Ecuador","otherGeospatial":"Galapagos Islands","volume":"11","noUsgsAuthors":false,"publicationDate":"2010-11-18","publicationStatus":"PW","scienceBaseUri":"50c86468e4b03bc63bd67a23","contributors":{"authors":[{"text":"Gromme, Sherman","contributorId":59318,"corporation":false,"usgs":true,"family":"Gromme","given":"Sherman","email":"","affiliations":[],"preferred":false,"id":470072,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mankinen, Edward A. 0000-0001-7496-2681 emank@usgs.gov","orcid":"https://orcid.org/0000-0001-7496-2681","contributorId":1054,"corporation":false,"usgs":true,"family":"Mankinen","given":"Edward","email":"emank@usgs.gov","middleInitial":"A.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":470071,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Prevot, Michel","contributorId":60510,"corporation":false,"usgs":true,"family":"Prevot","given":"Michel","email":"","affiliations":[],"preferred":false,"id":470073,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

A stratigraphically constrained set of samples have compositions that range from basalt through basaltic andesite, andesite, dacite, and rhyolite. The major and trace element range can be modeled by 80–90% closed-system crystal fractionation over a temperature interval from 1279°C to 719°C at 100 MPa, with an implied volume of parental basalt of ∼65 km<sup>3</sup>. Numerical models suggest, for wall rock temperatures appropriate to this depth, that 90% of this volume of magma would cool and crystallize over this temperature interval within a few tens of kiloyears. However, the range in <sup>87</sup>Sr/<sup>86</sup>Sr, (<sup>230</sup>Th/<sup>238</sup>U), and (<sup>226</sup>Ra/<sup>230</sup>Th) requires open-system processes. Assimilation of the host sediments can replicate the range of Sr isotopes. The variation of (<sup>226</sup>Ra/<sup>230</sup>Th) ratios in the basalt to andesite compositional range requires that these were generated less than several thousand years before eruption. Residence times for dacites are close to 8000 years, whereas the rhyolites appear to be 50–200 kyr old. Thus, the magmas that erupted within only 60 h had a wide range of crustal residence times.

This fish was the most abundant deepwater cisco species in Lake Superior in the early 1920s but presently makes up less than 1% of all deepwater ciscoes (i.e., including shortjaw cisco, bloater <i>C. hoyi</i>, and <i>kiyi C. kiyi</i>) captured in biological surveys. Directed overfishing of deepwater cisco species during the 1930s and again during the mid-1960s and 1970s has been suggested as the cause of the shortjaw cisco's demise. In this paper, we re-examined the overfishing hypothesis by using historical and recent survey data to estimate the proportion of the historical commercial fishery landings that comprised shortjaw ciscoes. We developed time series of estimated harvest and relative abundance for all statistical districts in Michigan waters of Lake Superior during 1929–1996, for which aggregate catch and effort data were available but not previously examined. The spatial distribution of the fishery and the relationships of catch to fishing effort were examined for evidence of overfishing. Our analysis suggested that directed overfishing was probably not the cause of shortjaw cisco demise, as this species appeared to be declining in all statistical districts regardless of the intensity of the fishery. A count-based population viability analysis indicated that quasi-extinction of the shortjaw cisco is highly probable in the near future. We propose an alternative hypothesis based on the decline of Lake Superior's keystone predator, the lake trout <i>Salvelinus namaycush</i>, which resulted in an expansion of the population of its principal prey, the cisco <i>C. artedi</i>, due to release from predation pressure. Competitive or predation interactions between the cisco and shortjaw cisco may be more likely explanations for the demise of the latter species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis Online","publisherLocation":"Philadelphia, PA","doi":"10.1577/T09-019.1","usgsCitation":"Bronte, C.R., Hoff, M.H., Gorman, O.T., Thogmartin, W.E., Schneeberger, P.J., and Todd, T.N., 2010, Decline of shortjaw cisco in Lake Superior: the role of overfishing and risk of extinction: Transactions of the American Fisheries Society, v. 139, no. 3, p. 735-748, https://doi.org/10.1577/T09-019.1.","productDescription":"14 p.","startPage":"735","endPage":"748","ipdsId":"IP-017838","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":264640,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":264639,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/T09-019.1"}],"country":"United States;Canada","otherGeospatial":"Lake Superior","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -92.1122,46.41 ], [ -92.1122,48.8794 ], [ -84.354,48.8794 ], [ -84.354,46.41 ], [ -92.1122,46.41 ] ] ] } } ] }","volume":"139","issue":"3","noUsgsAuthors":false,"publicationDate":"2011-01-09","publicationStatus":"PW","scienceBaseUri":"50d9f4dfe4b07a5aecdeff61","contributors":{"authors":[{"text":"Bronte, Charles R.","contributorId":83050,"corporation":false,"usgs":true,"family":"Bronte","given":"Charles","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":470297,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hoff, Michael H.","contributorId":23878,"corporation":false,"usgs":true,"family":"Hoff","given":"Michael","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":470294,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gorman, Owen T. 0000-0003-0451-110X otgorman@usgs.gov","orcid":"https://orcid.org/0000-0003-0451-110X","contributorId":2888,"corporation":false,"usgs":true,"family":"Gorman","given":"Owen","email":"otgorman@usgs.gov","middleInitial":"T.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":470293,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Thogmartin, Wayne E. 0000-0002-2384-4279 wthogmartin@usgs.gov","orcid":"https://orcid.org/0000-0002-2384-4279","contributorId":2545,"corporation":false,"usgs":true,"family":"Thogmartin","given":"Wayne","email":"wthogmartin@usgs.gov","middleInitial":"E.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":470292,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Schneeberger, Philip J.","contributorId":43313,"corporation":false,"usgs":true,"family":"Schneeberger","given":"Philip","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":470296,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Todd, Thomas N.","contributorId":42547,"corporation":false,"usgs":true,"family":"Todd","given":"Thomas","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":470295,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Here we present the relation between repose time and the cumulative moment magnitude (CMM) as a tool to aid in differentiating between an eruption and a period of unrest. In several case studies, the CMM is lower at shorter repose times than it is at longer repose times. The relationship between repose time and CMM may be linear in log-log space, particularly at Mount St. Helens.

Turtle biomass in freshwater systems can be an order of magnitude greater than that of endotherms. Therefore, declines in freshwater turtle populations can change energy transfer in freshwater systems. Here we report on a mark&ndash;recapture study at a lake and adjacent borrow pit in a relict tract of bottomland hardwood forest in the Mississippi River floodplain in southeast Missouri, which was designed to gather baseline data, including sex ratio, size structure, and population size, density, and biomass, for the freshwater turtle population. Using a variety of capture methods, we captured seven species of freshwater turtles (snapping turtle <i>Chelydra serpentina</i>; red-eared slider <i>Trachemys scripta</i>; southern painted turtle <i>Chrysemys dorsalis</i>; river cooter <i>Pseudemys concinna</i>; false map turtle <i>Graptemys pseudogeographica</i>; eastern musk turtle <i>Sternotherus odoratus</i>; spiny softshell <i>Apalone spinifera</i>) comprising four families (Chelydridae, Emydidae, Kinosternidae, Trinoychidae). With the exception of red-eared sliders, nearly all individuals captured were adults. Most turtles were captured by baited hoop-nets, and this was the only capture method that caught all seven species. The unbaited fyke net was very successful in the borrow pit, but only captured four of the seven species. Basking traps and deep-water crawfish nets had minimal success. Red-eared sliders had the greatest population estimate (2,675), density (205/ha), and biomass (178 kg/ha). Two species exhibited a sex-ratio bias: snapping turtles <i>C. serpentina</i> in favor of males, and spiny softshells <i>A. spinifera</i> in favor of females.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Fish and Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"U.S. Fish & Wildlife Service","publisherLocation":"Lawrence, KS","doi":"10.3996/072010-JFWM-020","usgsCitation":"Glorioso, B.M., Vaughn, A.J., and Waddle, J., 2010, The aquatic turtle assemblage inhabiting a highly altered landscape in southeast Missouri: Journal of Fish and Wildlife Management, v. 1, no. 2, p. 161-168, https://doi.org/10.3996/072010-JFWM-020.","productDescription":"8 p.","startPage":"161","endPage":"168","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":475530,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3996/072010-jfwm-020","text":"Publisher Index Page"},{"id":269326,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3996/072010-JFWM-020"},{"id":204187,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Missouri","otherGeospatial":"Mississippi River Floodplain","volume":"1","issue":"2","noUsgsAuthors":false,"publicationDate":"2010-11-30","publicationStatus":"PW","scienceBaseUri":"505ba9cce4b08c986b322505","contributors":{"authors":[{"text":"Glorioso, Brad M. 0000-0002-5400-7414 gloriosob@usgs.gov","orcid":"https://orcid.org/0000-0002-5400-7414","contributorId":4241,"corporation":false,"usgs":true,"family":"Glorioso","given":"Brad","email":"gloriosob@usgs.gov","middleInitial":"M.","affiliations":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":347190,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Vaughn, Allison J.","contributorId":57200,"corporation":false,"usgs":true,"family":"Vaughn","given":"Allison","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":347191,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Waddle, J.

Due in part to the species’ lack of popularity as a game and commercial fish, few regions consider burbot in management plans. We review the worldwide population status of burbot and synthesize reasons why some burbot populations are endangered or declining, some burbot populations have recovered and some burbot populations do not recover despite management measures. Burbot have been extirpated in much of Western Europe and the United Kingdom and are threatened or endangered in much of North America and Eurasia. Pollution and habitat change, particularly the effects of dams, appear to be the main causes for declines in riverine burbot populations. Pollution and the adverse effects of invasive species appear to be the main reasons for declines in lacustrine populations. Warmer water temperatures, due either to discharge from dams or climate change, have been noted in declining burbot populations at the southern extent of their range. Currently, fishing pressure does not appear to be limiting burbot populations world-wide. We suggest mitigation measures for burbot population recovery, particularly those impacted by dams and invasive species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Fish and Fisheries","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1111/j.1467-2979.2009.00340.x","usgsCitation":"Stapanian, M.A., Paragamian, V., Madenjian, C.P., Jackson, J.R., Lappalainen, J., Evenson, M.J., and Neufeld, M.D., 2010, Worldwide status of burbot and conservation measures: Fish and Fisheries, v. 11, no. 1, p. 34-56, https://doi.org/10.1111/j.1467-2979.2009.00340.x.","productDescription":"23 p.","startPage":"34","endPage":"56","ipdsId":"IP-013027","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":264952,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":264947,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1467-2979.2009.00340.x"}],"otherGeospatial":"Earth","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -180.0,-90.0 ], [ -180.0,90.0 ], [ 180.0,90.0 ], [ 180.0,-90.0 ], [ -180.0,-90.0 ] ] ] } } ] }","volume":"11","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-02-11","publicationStatus":"PW","scienceBaseUri":"50e58818e4b0a4aa5bb0a1be","contributors":{"authors":[{"text":"Stapanian, Martin A. 0000-0001-8173-4273 mstapanian@usgs.gov","orcid":"https://orcid.org/0000-0001-8173-4273","contributorId":3425,"corporation":false,"usgs":true,"family":"Stapanian","given":"Martin","email":"mstapanian@usgs.gov","middleInitial":"A.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":470922,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Paragamian, Vaughn L.","contributorId":9547,"corporation":false,"usgs":true,"family":"Paragamian","given":"Vaughn L.","affiliations":[],"preferred":false,"id":470923,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Madenjian, Charles P. 0000-0002-0326-164X cmadenjian@usgs.gov","orcid":"https://orcid.org/0000-0002-0326-164X","contributorId":2200,"corporation":false,"usgs":true,"family":"Madenjian","given":"Charles","email":"cmadenjian@usgs.gov","middleInitial":"P.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":470921,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jackson, James R.","contributorId":55709,"corporation":false,"usgs":false,"family":"Jackson","given":"James","email":"","middleInitial":"R.","affiliations":[{"id":12722,"text":"Cornell University","active":true,"usgs":false}],"preferred":false,"id":470926,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lappalainen, Jyrki","contributorId":67385,"corporation":false,"usgs":true,"family":"Lappalainen","given":"Jyrki","email":"","affiliations":[],"preferred":false,"id":470927,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Evenson, Matthew J.","contributorId":44434,"corporation":false,"usgs":true,"family":"Evenson","given":"Matthew","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":470925,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Neufeld, Matthew D.","contributorId":27335,"corporation":false,"usgs":true,"family":"Neufeld","given":"Matthew","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":470924,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

We have systematically evaluated existing uses of the ODD protocol and identified, as expected, parts of ODD needing improvement and clarification. Accordingly, we revise the definition of ODD to clarify aspects of the original version and thereby facilitate future standardization of ABM descriptions. We discuss frequently raised critiques in ODD but also two emerging, and unanticipated, benefits: ODD improves the rigorous formulation of models and helps make the theoretical foundations of large models more visible. Although the protocol was designed for ABMs, it can help with documenting any large, complex model, alleviating some general objections against such models.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.ecolmodel.2010.08.019","usgsCitation":"Grimm, V., Berger, U., DeAngelis, D.L., Polhill, J.G., Giske, J., and Railsback, S., 2010, The ODD protocol: A review and first update: Ecological Modelling, v. 221, no. 23, p. 2760-2768, https://doi.org/10.1016/j.ecolmodel.2010.08.019.","productDescription":"9 p.","startPage":"2760","endPage":"2768","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":475552,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.417.2226","text":"External Repository"},{"id":204392,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"221","issue":"23","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba862e4b08c986b321bb9","contributors":{"authors":[{"text":"Grimm, Volker","contributorId":89656,"corporation":false,"usgs":true,"family":"Grimm","given":"Volker","email":"","affiliations":[],"preferred":false,"id":347991,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Berger, Uta","contributorId":59552,"corporation":false,"usgs":true,"family":"Berger","given":"Uta","email":"","affiliations":[],"preferred":false,"id":347988,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"DeAngelis, Donald L. 0000-0002-1570-4057 don_deangelis@usgs.gov","orcid":"https://orcid.org/0000-0002-1570-4057","contributorId":148065,"corporation":false,"usgs":true,"family":"DeAngelis","given":"Donald","email":"don_deangelis@usgs.gov","middleInitial":"L.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"preferred":true,"id":347990,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Polhill, J.

UV can be hazardous to some amphibians, but the resultant effects depend on a variety of environmental and behavioral factors. In this study, the potential effects of UV on the Northwestern Salamander, <i>Ambystoma gracile</i>, from three lakes were assessed in the laboratory using a solar simulator. We measured the survival of embryos and the survival and growth of larvae exposed to four UV treatments in controlled laboratory studies, the UV absorbance of egg jelly, oviposition depths in the lakes, and UV absorbance in water samples from the three lakes. Hatching success of embryos decreased in the higher UV treatments as compared to the control treatments, and growth of surviving larvae was significantly reduced in the higher UVB irradiance treatments. The egg jelly exhibited a small peak of absorbance within the UVB range (290&ndash;320 nm). The magnitude of UV absorbance differed among egg jellies from the three lakes. Oviposition depths at the three sites averaged 1.10 m below the water surface. Approximately 66% of surface UVB radiation was attenuated at 10-cm depth in all three lakes. Results of this study indicate that larvae may be sensitive to UVB exposure under laboratory conditions; however, in field conditions the depths of egg deposition in the lakes, absorbance of UV radiation by the water column, and the potential for behavioral adjustments may mitigate severe effects of UV radiation.","language":"English","publisher":"Society for the Study of Amphibians and Reptiles","doi":"10.1670/09-061.1","usgsCitation":"Calfee, R.D., Little, E.E., Pearl, C., and Hoffman, R.L., 2010, The effects of simulated solar UVB radiation on early developmental stages of the Northwestern Salamander (Ambystoma gracile) from three lakes: Journal of Herpetology, v. 44, no. 4, p. 572-580, https://doi.org/10.1670/09-061.1.","productDescription":"9 p.","startPage":"572","endPage":"580","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true},{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":204290,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Washington","otherGeospatial":"Dick Lake, Harry Lake, Mount Ranier National Park, Sunrise Lake","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.76010131835938,\n              46.81086929621387\n            ],\n            [\n              -121.51359558105469,\n              46.81086929621387\n            ],\n            [\n              -121.51359558105469,\n              46.991494313050424\n            ],\n            [\n              -121.76010131835938,\n              46.991494313050424\n            ],\n            [\n              -121.76010131835938,\n              46.81086929621387\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"44","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bab9be4b08c986b322f55","contributors":{"authors":[{"text":"Calfee, Robin D. 0000-0001-6056-7023 rcalfee@usgs.gov","orcid":"https://orcid.org/0000-0001-6056-7023","contributorId":1841,"corporation":false,"usgs":true,"family":"Calfee","given":"Robin","email":"rcalfee@usgs.gov","middleInitial":"D.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":348397,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Little, Edward E. 0000-0003-0034-3639 elittle@usgs.gov","orcid":"https://orcid.org/0000-0003-0034-3639","contributorId":1746,"corporation":false,"usgs":true,"family":"Little","given":"Edward","email":"elittle@usgs.gov","middleInitial":"E.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":348396,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pearl, Christopher A. christopher_pearl@usgs.gov","contributorId":145515,"corporation":false,"usgs":true,"family":"Pearl","given":"Christopher A.","email":"christopher_pearl@usgs.gov","affiliations":[{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true}],"preferred":false,"id":348399,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hoffman, Robert L.","contributorId":52931,"corporation":false,"usgs":true,"family":"Hoffman","given":"Robert","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":348398,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Instead, hundreds of manatees aggregate at artificial canals, basins, and natural deep water sites that act as passive thermal refugia (PTR). Monitoring at two canal sites revealed temperature inverted haloclines, which provided warm salty bottom layers that generally remained above temperatures considered adverse for manatees. At the largest PTR, the warmer bottom layer disappeared unless significant salt stratification was maintained by upstream freshwater inflow over a persistent tidal wedge. A detailed three-dimensional hydrology model showed that salinity stratification inhibited vertical convection induced by atmospheric cooling.

During this time, numerous studies have improved our understanding of how use-related, environmental and managerial factors affect ecological conditions and processes. Most studies have focused on vegetation and soil responses to recreation-related trampling on trails and recreation sites using indicators such as percent vegetation cover and exposed mineral soil. This applied approach has and will continue to yield important information for land managers. However, for the field to advance, more attention needs to be given to other ecosystem attributes and to the larger aspects of environmental conservation occurring at landscape scales. This article is an effort at initiating a dialog on needed advances in the field. We begin by reviewing broadly generalizable knowledge of recreation ecology, to separate what is known from research gaps. Then, based on the authors’ perspective of research in the USA and North America, several research directions are suggested as essential for continued progress in this field including theoretical development, broadening scale, integration with other disciplines, and examination of synergistic effects.</span></p>","language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s00267-009-9406-5","usgsCitation":"Monz, C.A., Cole, D.N., Leung, Y., and Marion, J.L., 2010, Sustaining visitor use in protected areas: Future opportunities in recreation ecology research based on the USA experience: Environmental Management, v. 45, no. 3, p. 551-562, https://doi.org/10.1007/s00267-009-9406-5.","productDescription":"12 p.","startPage":"551","endPage":"562","numberOfPages":"12","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":204507,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"45","issue":"3","noUsgsAuthors":false,"publicationDate":"2009-12-17","publicationStatus":"PW","scienceBaseUri":"505ba324e4b08c986b31fbc1","contributors":{"authors":[{"text":"Monz, Christopher A.","contributorId":10538,"corporation":false,"usgs":true,"family":"Monz","given":"Christopher","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":349305,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cole, David N.","contributorId":40086,"corporation":false,"usgs":true,"family":"Cole","given":"David","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":349306,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Leung, Yu-Fai","contributorId":95730,"corporation":false,"usgs":true,"family":"Leung","given":"Yu-Fai","affiliations":[],"preferred":false,"id":349308,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Marion, Jeffrey L.","contributorId":56322,"corporation":false,"usgs":true,"family":"Marion","given":"Jeffrey","email":"","middleInitial":"L.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":349307,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The SSC regimes were plotted as curves showing concentrations and durations of the annual longest and tenth-longest SSC excursions above 18 concentrations for water years 2005-2008 in Copperas Branch and water years 2006 and 2008 in Kelley Creek. Both streams have fish communities remarkably diverse for their small drainage basin areas (420 and 565 ha, respectively), and represent biological reference conditions with respect to SSC. SSC-regime curves were similar for the two sites across water years. The measured SSC regimes reached or exceeded published experimentally based SSC impairment thresholds and plotted below a proposed long-term SSC reference regime for the Interior Plateau ecoregion (Ecoregion 71), suggesting that neither the experimentally based thresholds nor the proposed SSC reference regime adequately reflect the relation between SSC and biological impairment for Western Highland Rim headwater streams. The SSC regimes of the two study streams were similar to the estimated SSC regime of an unimpaired East Tennessee trout stream. Additional field studies are needed to describe SSC regimes in streams of varying basin scale, level of impairment, and region.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the American Water Resources Association","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Water Resources Association","publisherLocation":"Middleburg, VA","doi":"10.1111/j.1752-1688.2010.00460.x","usgsCitation":"Diehl, T.H., and Wolfe, W., 2010, Suspended-sediment concentration regimes for two biological reference streams in Middle Tennessee: Journal of the American Water Resources Association, v. 46, no. 4, p. 824-837, https://doi.org/10.1111/j.1752-1688.2010.00460.x.","productDescription":"14 p.","startPage":"824","endPage":"837","temporalStart":"2004-10-01","temporalEnd":"2008-09-30","costCenters":[{"id":581,"text":"Tennessee Water Science Center","active":true,"usgs":true}],"links":[{"id":475555,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1752-1688.2010.00460.x","text":"Publisher Index Page"},{"id":204264,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269119,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.2010.00460.x"}],"country":"United States","state":"Tennessee","volume":"46","issue":"4","noUsgsAuthors":false,"publicationDate":"2010-07-26","publicationStatus":"PW","scienceBaseUri":"505ba311e4b08c986b31fb6d","contributors":{"authors":[{"text":"Diehl, Timothy H. 0000-0001-9691-2212 thdiehl@usgs.gov","orcid":"https://orcid.org/0000-0001-9691-2212","contributorId":546,"corporation":false,"usgs":true,"family":"Diehl","given":"Timothy","email":"thdiehl@usgs.gov","middleInitial":"H.","affiliations":[{"id":581,"text":"Tennessee Water Science Center","active":true,"usgs":true},{"id":24708,"text":"Lower Mississippi-Gulf Water Science Center","active":true,"usgs":true}],"preferred":true,"id":347378,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wolfe, William J. wjwolfe@usgs.gov","contributorId":1888,"corporation":false,"usgs":true,"family":"Wolfe","given":"William J.","email":"wjwolfe@usgs.gov","affiliations":[{"id":581,"text":"Tennessee Water Science Center","active":true,"usgs":true}],"preferred":false,"id":347379,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
