Brook trout Salvelinus fontinalis from Isle Royale, Michigan, three Minnesota tributaries of Lake Superior, and Lake Nipigon in Ontario were analyzed for genetic variation at 12 microsatellite DNA loci. Analysis of molecular variance, genetic distance measures, and cluster analysis were used to examine the diversity, gene flow, and relatedness among the samples. The diversity estimates for the samples from Isle Royale were similar to those for the samples collected from Minnesota tributaries of Lake Superior, and all estimates were lower than those reported in other studies of brook trout from eastern North America. Genetic differences were detected among the brook trout at Isle Royale, Lake Nipigon, and the Minnesota tributaries of Lake Superior. Further, the population in Tobin Harbor at the eastern end of Isle Royale was distinct from the populations from tributaries at the southwestern end of the island. The Minnesota tributary population formed a group that was genetically distinct from those from Isle Royale and Lake Nipigon. The Isle Royale population should be managed to preserve the genetic and phenotypic variation that distinguishes it from the other brook trout populations analyzed to date.

This location provides detail of both creeping fault landform development and complex fault zone kinematics. Here, the SAF creeps 10–14 mm/yr slower than at locations ∼20 km along the fault in either direction. This spatial change in creep rate is coincident with a series of en echelon oblique-normal faults that strike obliquely to the SAF and may accommodate the missing deformation. This study presents a suite of analyses that are helpful for proper mapping of faults in locations where high-resolution topographic data are available. Furthermore, our analyses indicate that two large subsidiary faults near the center of the step over zone appear to carry significant distributed deformation based on their large apparent vertical offsets, the presence of associated sag ponds and fluvial knickpoints, and the observation that they are rotating a segment of the main SAF. Several subsidiary faults in the southeastern portion of Mustang Ridge are likely less active; they have few associated sag ponds and have older scarp morphologic ages and subdued channel knickpoints. Several faults in the northwestern part of Mustang Ridge, though relatively small, are likely also actively accommodating active fault slip based on their young morphologic ages and the presence of associated sag ponds.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Tectonics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union (AGU)","publisherLocation":"Washington, D.C.","doi":"10.1029/2010TC002673","usgsCitation":"DeLong, S.B., Hilley, G.E., Rymer, M.J., and Prentice, C., 2010, Fault zone structure from topography: signatures of en echelon fault slip at Mustang Ridge on the San Andreas Fault, Monterey County, California: Tectonics, v. 29, TC5003: 16 p., https://doi.org/10.1029/2010TC002673.","productDescription":"TC5003: 16 p.","ipdsId":"IP-018444","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":264969,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":264968,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2010TC002673"}],"country":"United States","state":"California","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -121.0,36.0 ], [ -121.0,36.5 ], [ -120.5,36.5 ], [ -120.5,36.0 ], [ -121.0,36.0 ] ] ] } } ] }","volume":"29","noUsgsAuthors":false,"publicationDate":"2010-09-02","publicationStatus":"PW","scienceBaseUri":"50e5d127e4b0a4aa5bb0b177","contributors":{"authors":[{"text":"DeLong, Stephen B. 0000-0002-0945-2172 sdelong@usgs.gov","orcid":"https://orcid.org/0000-0002-0945-2172","contributorId":5240,"corporation":false,"usgs":true,"family":"DeLong","given":"Stephen","email":"sdelong@usgs.gov","middleInitial":"B.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":470377,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hilley, George E.","contributorId":85484,"corporation":false,"usgs":true,"family":"Hilley","given":"George","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":470378,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rymer, Michael J. mrymer@usgs.gov","contributorId":1522,"corporation":false,"usgs":true,"family":"Rymer","given":"Michael","email":"mrymer@usgs.gov","middleInitial":"J.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":470376,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Prentice, Carol","contributorId":103549,"corporation":false,"usgs":true,"family":"Prentice","given":"Carol","affiliations":[],"preferred":false,"id":470379,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70041334,"text":"70041334 - 2010 - Infrasonic harmonic tremor and degassing bursts from Halema'uma'u Crater, Kilauea Volcano, Hawaii","interactions":[],"lastModifiedDate":"2012-12-14T13:42:37","indexId":"70041334","displayToPublicDate":"2012-12-10T00:00:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2312,"text":"Journal of Geophysical Research","active":true,"publicationSubtype":{"id":10}},"title":"Infrasonic harmonic tremor and degassing bursts from Halema'uma'u Crater, Kilauea Volcano, Hawaii","docAbstract":"The formation, evolution, collapse, and subsequent resurrection of a vent within Halema'uma'u Crater, Kilauea Volcano, produced energetic and varied degassing signals recorded by a nearby infrasound array between 2008 and early 2009. After 25 years of quiescence, a vent-clearing explosive burst on 19 March 2008 produced a clear, complex acoustic signal. Near-continuous harmonic infrasonic tremor followed this burst until 4 December 2008, when a period of decreased degassing occurred. The tremor spectra suggest volume oscillation and reverberation of a shallow gas-filled cavity beneath the vent. The dominant tremor peak can be sustained through Helmholtz oscillations of the cavity, while the secondary tremor peak and overtones are interpreted assuming acoustic resonance. The dominant tremor frequency matches the oscillation frequency of the gas emanating from the vent observed by video. Tremor spectra and power are also correlated with cavity geometry and dynamics, with the cavity depth estimated at ~219 m and volume ~3 x 106 m3 in November 2008. Over 21 varied degassing bursts were observed with extended burst durations and frequency content consistent with a transient release of gas exciting the cavity into resonance. Correlation of infrasound with seismicity suggests an open system connecting the atmosphere to the seismic excitation process at depth. Numerous degassing bursts produced very long period (0.03-0.1 Hz) infrasound, the first recorded at Kilauea, indicative of long-duration atmospheric accelerations. Kilauea infrasound appears controlled by the exsolution of gas from the magma, and the interaction of this gas with the conduits and cavities confining it.","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":"10.1029/2010JB007642","usgsCitation":"Fee, D., Garces, M., Patrick, M., Chouet, B., Dawson, P., and Swanson, D., 2010, Infrasonic harmonic tremor and degassing bursts from Halema'uma'u Crater, Kilauea Volcano, Hawaii: Journal of Geophysical Research, v. 115, 15 p.; B11316, https://doi.org/10.1029/2010JB007642.","productDescription":"15 p.; B11316","numberOfPages":"15","ipdsId":"IP-023579","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":336,"text":"Hawaiian Volcano Observatory","active":false,"usgs":true}],"links":[{"id":264051,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":264050,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2010JB007642"}],"country":"United States","state":"Hawai'i","otherGeospatial":"Kilauea Volcano","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -155.3,19.3 ], [ -155.3,19.5 ], [ -155.0,19.5 ], [ -155.0,19.3 ], [ -155.3,19.3 ] ] ] } } ] }","volume":"115","noUsgsAuthors":false,"publicationDate":"2010-11-30","publicationStatus":"PW","scienceBaseUri":"50cc58f4e4b00ab7c548c6b4","contributors":{"authors":[{"text":"Fee, David","contributorId":77761,"corporation":false,"usgs":true,"family":"Fee","given":"David","affiliations":[],"preferred":false,"id":469551,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Garces, Milton","contributorId":101166,"corporation":false,"usgs":true,"family":"Garces","given":"Milton","email":"","affiliations":[],"preferred":false,"id":469552,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Patrick, Matt","contributorId":69033,"corporation":false,"usgs":true,"family":"Patrick","given":"Matt","email":"","affiliations":[],"preferred":false,"id":469550,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Chouet, Bernard","contributorId":65485,"corporation":false,"usgs":true,"family":"Chouet","given":"Bernard","affiliations":[],"preferred":false,"id":469549,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Dawson, Phil","contributorId":18647,"corporation":false,"usgs":true,"family":"Dawson","given":"Phil","email":"","affiliations":[],"preferred":false,"id":469548,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Swanson, Donald A. 0000-0002-1680-3591 donswan@usgs.gov","orcid":"https://orcid.org/0000-0002-1680-3591","contributorId":3137,"corporation":false,"usgs":true,"family":"Swanson","given":"Donald A.","email":"donswan@usgs.gov","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":false,"id":469547,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}} ,{"id":70042201,"text":"70042201 - 2010 - Genetic diversity of lake whitefish in lakes Michigan and Huron: sampling, standardization, and research priorities","interactions":[],"lastModifiedDate":"2013-01-16T20:39:01","indexId":"70042201","displayToPublicDate":"2012-12-10T00:00:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2330,"text":"Journal of Great Lakes Research","active":true,"publicationSubtype":{"id":10}},"title":"Genetic diversity of lake whitefish in lakes Michigan and Huron: sampling, standardization, and research priorities","docAbstract":"We combined data from two laboratories to increase the spatial extent of a genetic data set for lake whitefish Coregonus clupeaformis from lakes Huron and Michigan and saw that genetic diversity was greatest between lakes, but that there was also structuring within lakes. Low diversity among stocks may be a reflection of relatively recent colonization of the Great Lakes, but other factors such as recent population fluctuation and localized stresses such as lamprey predation or heavy exploitation may also have a homogenizing effect. Our data suggested that there is asymmetrical movement of lake whitefish between Lake Huron and Lake Michigan; more genotypes associated with Lake Michigan were observed in Lake Huron. Adding additional collections to the calibrated set will allow further examination of diversity in other Great Lakes, answer questions regarding movement among lakes, and estimate contributions of stocks to commercial yields. As the picture of genetic diversity and population structure of lake whitefish in the Great Lakes region emerges, we need to develop methods to combine data types to help identify important areas for biodiversity and thus conservation. Adding genetic data to existing models will increase the precision of predictions of the impacts of new stresses and changes in existing pressures on an ecologically and commercially important species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"International Association for Great Lakes Research","publisherLocation":"Ann Arbor, MI","doi":"10.1016/j.jglr.2010.01.004","usgsCitation":"Stott, W., VanDeHey, J.A., and Sloss, B.L., 2010, Genetic diversity of lake whitefish in lakes Michigan and Huron: sampling, standardization, and research priorities: Journal of Great Lakes Research, v. 36, no.

of Lake Michigan: Implications for future rehabilitation","docAbstract":"The Northern Refuge was established in 1985 as part of the lake trout Salvelinus namaycush rehabilitation effort for Lake Michigan. To evaluate progress toward lake trout rehabilitation in the Northern Refuge, we conducted annual (1991–2008) gill-net surveys in the fall to assess the adult population and beam trawl surveys in the spring to assess naturally reproduced age-0 lake trout. Our criteria for evaluating progress included the density of “wild” age-0 fish within the Northern Refuge, the proportion of wild fish within the adult population, density of spawners, adult survival, growth, and wounding rate by sea lampreys Petromyzon marinus. No wild age-0 lake trout were caught in the Northern Refuge during 1991–2008. Overall, wild lake trout did not recruit to the adult population to any detectable degree. The mean density of spawning lake trout decreased from 45 fish·305 m of gill net−1·d−1 during 1991–1999 to only 4 fish·305 m−1·d−1 during 2000–2008. Although the sea lamprey wounding rate more than doubled between these two time periods, catch curve analysis revealed that mortality of adult lake trout actually decreased between the two periods. Therefore, the 90% decrease in abundance of spawning lake trout between the two periods could not be attributed to increased sea lamprey predation but instead was probably due in part to the reduced lake trout stocking rate during 1995–2005. The paucity of natural reproduction in the Northern Refuge during 1991–2008 most likely resulted from alewife Alosa pseudoharengus interference with lake trout reproduction and from the relatively low lake trout spawner density during 2000–2008. Our results suggest that the annual stocking rate of lake trout yearlings should be increased to at least 250,000 fish/reef to achieve greater densities of spawners.","language":"English","publisher":"Taylor & Francis ","doi":"10.1577/M09-108.1","usgsCitation":"Madenjiana, C.P., and Desorcie, T.J., 2010, Lake trout population dynamics in the Northern Refuge of Lake Michigan: Implications for future rehabilitation: North American Journal of Fisheries Management, v. 30, no. 3, p. 629-641, https://doi.org/10.1577/M09-108.1.","productDescription":"13 p.","startPage":"629","endPage":"641","ipdsId":"IP-015186","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":264866,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Lake Michigan","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -88.0,41.6 ], [ -88.0,46.0 ], [ -84.9,46.0 ], [ -84.9,41.6 ], [ -88.0,41.6 ] ] ] } } ] }","volume":"30","issue":"3","noUsgsAuthors":false,"publicationDate":"2010-06-01","publicationStatus":"PW","scienceBaseUri":"50df5897e4b0dfbe79e6b7d0","contributors":{"authors":[{"text":"Madenjiana, Charles P.","contributorId":53262,"corporation":false,"usgs":true,"family":"Madenjiana","given":"Charles","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":470617,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Desorcie, Timothy J. 0000-0002-9965-1668","orcid":"https://orcid.org/0000-0002-9965-1668","contributorId":23480,"corporation":false,"usgs":true,"family":"Desorcie","given":"Timothy","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":470616,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70041922,"text":"70041922 - 2010 - Method for calculating self-noise spectra and operating ranges for seismographic inertial sensors and recorders","interactions":[],"lastModifiedDate":"2012-12-31T13:49:35","indexId":"70041922","displayToPublicDate":"2012-12-01T00:00:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3372,"text":"Seismological Research Letters","onlineIssn":"1938-2057","printIssn":"0895-0695","active":true,"publicationSubtype":{"id":10}},"title":"Method for calculating self-noise spectra and operating ranges for seismographic inertial sensors and recorders","docAbstract":"Understanding the performance of sensors and recorders is prerequisite to making appropriate use of them in seismology and earthquake engineering. This paper explores a critical aspect of instrument performance, the “self” noise level of the device and the amplitude range it can usefully record. Self noise limits the smallest signals, while instrument clipping level creates the upper limit (above which it either cannot produce signals or becomes unacceptably nonlinear). Where these levels fall, and the “operating range” between them, determines much of the instrument's viability and the applications for which it is appropriate. The representation of seismic-instrument self-noise levels and their effective operating ranges (cf., dynamic range) for seismological inertial sensors, recorders (data acquisition units, or DAUs), and integrated systems of sensors and recorders (data acquisition systems, or DASs) forces one to address an unnatural comparison between transient finite-bandwidth signals, such as earthquake records, and the instrument's self noise, an effectively stationary signal of infinite duration. In addition to being transient, earthquakes and other records of interest are characterized by a peak amplitude and generally a narrow, peaked spectral shape. Unfortunately, any power spectrum computed for such transient signals is ill defined, since the maximum of that spectrum depends strongly upon signal and record durations. In contrast, the noise floor of an instrument is approximately stationary and properly described by a power spectral density (PSD) or its root (rPSD). Put another way, earthquake records have units of amplitude (e.g., m/s2) while PSDs have units of amplitude-squared per hertz (e.g., (m/s2)2/Hz) and the rPSD has units of amplitude per root of hertz (e.g., (m/s2)/Hz1/2). Thus, this incompatability is a conflict between earthquake (amplitude) and PSD (spectral density) units that requires one to make various assumptions before they can be compared. For purposes of instrument operational performance, we provide a means of evaluating signal and noise and the range between them in a manner representative of time-domain instrument performance. We call these “operating range diagrams” (ORDs), plots of instrument self noise and clipping level; the “operating range” is the range between these values. For frequency-domain performance we elect to show self noise as an rPSD that may be compared to another instrument's noise or to ambient Earth noise (e.g., Peterson 1993); however, to limit the number of arbitrary choices required to merge transient and stationary signals we do not compare the rPSD to transient signals in the frequency domain. Our solution for a time-domain comparison is not new but rather builds upon the consensus of the first and second Guidelines for Seismometer Testing workshops (Hutt et al. 2009) and long established practice in acoustics. We propose this method as a standard for characterizing seismic instruments, and it has been endorsed by the second workshop (Hutt et al. 2009, 2010) and the Advanced National Seismic System (ANSS) Working Group (2008) and recent ANSS procurement specifications.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Seismological Research Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Seismological Society of America","publisherLocation":"El Cerrito, CA","doi":"10.1785/gssrl.81.4.640","usgsCitation":"Evans, J.R., Followill, F., Hutt, C.R., Kromer, R., Nigbor, R., Ringler, A., Steim, J., and Wielandt, E., 2010, Method for calculating self-noise spectra and operating ranges for seismographic inertial sensors and recorders: Seismological Research Letters, v. 81, no. 4, p. 640-646, https://doi.org/10.1785/gssrl.81.4.640.","productDescription":"7 p.","startPage":"640","endPage":"646","ipdsId":"IP-015382","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":264981,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/gssrl.81.4.640"},{"id":264982,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"81","issue":"4","noUsgsAuthors":false,"publicationDate":"2010-07-01","publicationStatus":"PW","scienceBaseUri":"50e5d16de4b0a4aa5bb0b283","contributors":{"authors":[{"text":"Evans, John R. jrevans@usgs.gov","contributorId":529,"corporation":false,"usgs":true,"family":"Evans","given":"John","email":"jrevans@usgs.gov","middleInitial":"R.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":470385,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Followill, F.","contributorId":93357,"corporation":false,"usgs":true,"family":"Followill","given":"F.","affiliations":[],"preferred":false,"id":470391,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hutt, Charles R. 0000-0001-9033-9195 bhutt@usgs.gov","orcid":"https://orcid.org/0000-0001-9033-9195","contributorId":1622,"corporation":false,"usgs":true,"family":"Hutt","given":"Charles","email":"bhutt@usgs.gov","middleInitial":"R.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":470386,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kromer, R.P.","contributorId":21838,"corporation":false,"usgs":true,"family":"Kromer","given":"R.P.","email":"","affiliations":[],"preferred":false,"id":470388,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Nigbor, R.L.","contributorId":30699,"corporation":false,"usgs":true,"family":"Nigbor","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":470389,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Ringler, A.

We examined the diet of double-crested cormorants (Phalacrocorax auritas) prior to, and immediately after, round goby population expansion at two colonies, Pigeon and Snake Islands, in eastern Lake Ontario from 1999 to 2007. Cormorant diet was determined from the examination of 10,167 pellets collected over the nine-year period. By the second year round gobies were found in the diet (2002 at Snake Island and 2003 at Pigeon Island) they were the main species consumed by cormorants at each colony. The dominance of round goby in cormorant diets had a significant effect on both daily fish consumption and seasonal trends in fish consumption compared to the pre-goby years. Seasonal differences that were observed during the pre-goby years were lost once gobies became the main diet component of cormorants. The rapid switch to a benthic prey such as round goby, from a largely limnetic fish diet demonstrates the adaptive foraging ability of cormorants. Round goby may act as a buffer for yellow perch and smallmouth bass, two sport fish impacted by cormorant predation in eastern Lake Ontario.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"International Association for Great Lakes Research","publisherLocation":"Ann Arbor, MI","doi":"10.1016/j.jglr.2010.02.013","usgsCitation":"Johnson, J.H., Ross, R.M., McCullough, R.D., and Mathers, A., 2010, Diet shift of double-crested cormorants in eastern Lake Ontario associated with the expansion of the invasive round goby: Journal of Great Lakes Research, v. 36, no. 2, p. 242-247, https://doi.org/10.1016/j.jglr.2010.02.013.","productDescription":"6 p.","startPage":"242","endPage":"247","temporalStart":"1999-01-01","temporalEnd":"2007-12-31","ipdsId":"IP-016794","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":264780,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":264779,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jglr.2010.02.013"}],"country":"United States","otherGeospatial":"Lake Ontario","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -80.0,43.17 ], [ -80.0,44.36 ], [ -76.0,44.36 ], [ -76.0,43.17 ], [ -80.0,43.17 ] ] ] } } ] }","volume":"36","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e5d10fe4b0a4aa5bb0b105","contributors":{"authors":[{"text":"Johnson, James H. 0000-0002-5619-3871 jhjohnson@usgs.gov","orcid":"https://orcid.org/0000-0002-5619-3871","contributorId":389,"corporation":false,"usgs":true,"family":"Johnson","given":"James","email":"jhjohnson@usgs.gov","middleInitial":"H.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":470525,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ross, Robert M.","contributorId":62562,"corporation":false,"usgs":true,"family":"Ross","given":"Robert","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":470527,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McCullough, Russell D.","contributorId":98154,"corporation":false,"usgs":true,"family":"McCullough","given":"Russell","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":470528,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mathers, Alastair","contributorId":36786,"corporation":false,"usgs":true,"family":"Mathers","given":"Alastair","email":"","affiliations":[],"preferred":false,"id":470526,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70042092,"text":"70042092 - 2010 - Mechanisms for chemostatic behavior in catchments: implications for CO2 consumption by mineral weathering","interactions":[],"lastModifiedDate":"2017-01-18T13:43:43","indexId":"70042092","displayToPublicDate":"2012-12-01T00:00:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1213,"text":"Chemical Geology","active":true,"publicationSubtype":{"id":10}},"title":"Mechanisms for chemostatic behavior in catchments: implications for CO2 consumption by mineral weathering","docAbstract":"Concentrations of weathering products in streams often show relatively little variation compared to changes in discharge, both at event and annual scales. In this study, several hypothesized mechanisms for this “chemostatic behavior” were evaluated, and the potential for those mechanisms to influence relations between climate, weathering fluxes, and CO2 consumption via mineral weathering was assessed. Data from Loch Vale, an alpine catchment in the Colorado Rocky Mountains, indicates that cation exchange and seasonal precipitation and dissolution of amorphous or poorly crystalline aluminosilicates are important processes that help regulate solute concentrations in the stream; however, those processes have no direct effect on CO2 consumption in catchments. Hydrograph separation analyses indicate that old water stored in the subsurface over the winter accounts for about one-quarter of annual streamflow, and almost one-half of annual fluxes of Na and SiO2 in the stream; thus, flushing of old water by new water (snowmelt) is an important component of chemostatic behavior. Hydrologic flushing of subsurface materials further induces chemostatic behavior by reducing mineral saturation indices and increasing reactive mineral surface area, which stimulate mineral weathering rates. CO2 consumption by carbonic acid mediated mineral weathering was quantified using mass-balance calculations; results indicated that silicate mineral weathering was responsible for approximately two-thirds of annual CO2 consumption, and carbonate weathering was responsible for the remaining one-third. CO2 consumption was strongly dependent on annual precipitation and temperature; these relations were captured in a simple statistical model that accounted for 71% of the annual variation in CO2 consumption via mineral weathering in Loch Vale.","language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.chemgeo.2009.09.014","usgsCitation":"Clow, D.W., and Mast, M.A., 2010, Mechanisms for chemostatic behavior in catchments: implications for CO2 consumption by mineral weathering: Chemical Geology, v. 269, no. 1-2, p. 40-51, https://doi.org/10.1016/j.chemgeo.2009.09.014.","productDescription":"12 p.","startPage":"40","endPage":"51","ipdsId":"IP-017755","costCenters":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"links":[{"id":264971,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":264970,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.chemgeo.2009.09.014"}],"country":"United States","state":"Colorado","otherGeospatial":"Loch Vale","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -109.0,37.0 ], [ -109.0,41.0 ], [ -102.0,41.0 ], [ -102.0,37.0 ], [ -109.0,37.0 ] ] ] } } ] }","volume":"269","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e5d168e4b0a4aa5bb0b274","contributors":{"authors":[{"text":"Clow, David W. 0000-0001-6183-4824 dwclow@usgs.gov","orcid":"https://orcid.org/0000-0001-6183-4824","contributorId":1671,"corporation":false,"usgs":true,"family":"Clow","given":"David","email":"dwclow@usgs.gov","middleInitial":"W.","affiliations":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"preferred":true,"id":470759,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mast, M.
