At broad geographic scales, we determined the importance of environmental setting and land use in explaining variation in stream physical characteristics. We hypothesized that as the spatial scale decreased from national to regional, land use would explain more of the variation in stream physical characteristics because environmental settings become more homogeneous. At a national scale, stepwise linear regression indicated that environmental setting was more important in explaining variability in stream physical characteristics. Although statistically discernible, the amount of variation explained by land use was not remarkable due to low partial correlations. At level II ecoregion spatial scales (southeastern USA plains, central USA plains, and a combination of the western Cordillera and the western interior basins and ranges), environmental setting variables were again more important predictors of stream physical characteristics, however, as the spatial scale decreased from national to regional, the portion of variability in stream physical characteristics explained by basin land use increased. Development of stream habitat indicators of land use will depend upon an understanding of relations between stream physical characteristics and environmental factors at multiple spatial scales. Smaller spatial scales will be necessary to reduce the confounding effects of variable environmental settings before the effects of land use can be reliably assessed.</p></div></div>","language":"English","publisher":"Springer","doi":"10.1007/s10661-006-9439-7","issn":"01676369","usgsCitation":"Goldstein, R.M., Carlisle, D., Meador, M.R., and Short, T., 2007, Can basin land use effects on physical characteristics of streams be determined at broad geographic scales?: Environmental Monitoring and Assessment, v. 130, no. 1-3, p. 495-510, https://doi.org/10.1007/s10661-006-9439-7.","productDescription":"16 p.","startPage":"495","endPage":"510","numberOfPages":"16","costCenters":[],"links":[{"id":239222,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"130","issue":"1-3","noUsgsAuthors":false,"publicationDate":"2006-11-15","publicationStatus":"PW","scienceBaseUri":"5059f332e4b0c8380cd4b65d","contributors":{"authors":[{"text":"Goldstein, R.

Because Corn Belt watersheds have been identified as major sources of N in the Mississippi River basin, the fate and transport of N from midwestern agricultural watersheds have received considerable interest. The fate and transport of N in the shallow ground water of these watersheds still needs additional research. Our purpose was to estimate denitrification in the shallow ground water of a tile-drained, Corn Belt watershed with fine-grained soils. Over a 3-yr period, N was monitored in the surface and ground water of an agricultural watershed in central Illinois. A significant amount of N was transported past the tile drains and into shallow ground water. The ground water nitrate was isotopically heavier than tile drain nitrate, which can be explained by denitrification in the subsurface. Denitrifying bacteria were found at depths to 10 m throughout the watershed. Laboratory and push-pull tests showed that a significant fraction of nitrate could be denitrified rapidly. We estimated that the N denitrified in shallow ground water was equivalent to 0.3 to 6.4% of the applied N or 9 to 27% of N exported via surface water. These estimates varied by water year and peaked in a year of normal precipitation after 2 yr of below average precipitation. Three years of monitoring data indicate that shallow ground water in watersheds with fine-grained soils may be a significant N sink compared with N exported via surface water. ??

NO3 is a common contaminant in shallow ground water in this area, whereas high concentrations of NH4-N (up to 39 mg/L) are present in deep ground water. N concentrations, N/Cl ratios, tracer-based apparent ground-water ages, N isotope data, and hydraulic gradients indicate that septic tank effluent is the primary source of NO3. N isotope data, N/Cl and N/C relations, 3H data, and hydraulic considerations point to a natural, sedimentary organic matter source for the high concentrations of NH4, and are inconsistent with an origin as septic tank N. Low recharge rates and flow velocities have largely restricted anthropogenic NO3 to isolated plumes within several meters of the water table. A variety of geochemical and isotopic data indicate that denitrification also affects NO3 gradients in the aquifer. Ground water in the La Pine aquifer evolves from oxic to increasingly reduced conditions. Suboxic conditions are achieved after about 15-30 y of transport below the water table. NO3 is denitrified near the oxic/suboxic boundary. Denitrification in the La Pine aquifer is characterized well at the aquifer scale with a redox boundary approach that inherently captures spatial variability in the distribution of electron donors.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.jhydrol.2006.09.013","issn":"00221694","usgsCitation":"Hinkle, S.R., Bohlke, J.K., Duff, J.H., Morgan, D.S., and Weick, R.J., 2007, Aquifer-scale controls on the distribution of nitrate and ammonium in ground water near La Pine, Oregon, USA: Journal of Hydrology, v. 333, no. 2-4, p. 486-503, https://doi.org/10.1016/j.jhydrol.2006.09.013.","productDescription":"18 p.","startPage":"486","endPage":"503","numberOfPages":"18","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":242337,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Oregon","city":"La Pine","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -121.75,43.5 ], [ -121.75,44 ], [ -121.33333333333333,44 ], [ -121.33333333333333,43.5 ], [ -121.75,43.5 ] ] ] } } ] }","volume":"333","issue":"2-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ed25e4b0c8380cd4965e","contributors":{"authors":[{"text":"Hinkle, Stephen R. srhinkle@usgs.gov","contributorId":1171,"corporation":false,"usgs":true,"family":"Hinkle","given":"Stephen","email":"srhinkle@usgs.gov","middleInitial":"R.","affiliations":[{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"preferred":true,"id":434887,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bohlke, John Karl 0000-0001-5693-6455 jkbohlke@usgs.gov","orcid":"https://orcid.org/0000-0001-5693-6455","contributorId":127841,"corporation":false,"usgs":true,"family":"Bohlke","given":"John","email":"jkbohlke@usgs.gov","middleInitial":"Karl","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":false,"id":434888,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Duff, John H. jhduff@usgs.gov","contributorId":961,"corporation":false,"usgs":true,"family":"Duff","given":"John","email":"jhduff@usgs.gov","middleInitial":"H.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":434886,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Morgan, David S.","contributorId":73181,"corporation":false,"usgs":true,"family":"Morgan","given":"David","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":434885,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Weick, Rodney J.","contributorId":79560,"corporation":false,"usgs":true,"family":"Weick","given":"Rodney","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":434889,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Median concentrations of Cd, Cu, and Zn in water throughout the watershed exceeded the U.S. EPA acute and chronic criteria for protection of aquatic life. Concentrations of As, Cd, Cu, Pb, and Zn in sediment were sufficient in the tributaries to cause invertebrate toxicity. The concentrations of As, Cu, Cd, Pb, and Zn in invertebrates from lower Cataract Creek (63, 339, 59, 34, and 2,410&nbsp;μg/g dry wt, respectively) were greater than the concentrations in invertebrates from the Clark Fork River watershed, Montana (19, 174, 2.3, 15, and 648&nbsp;μg/g, respectively), that were associated with reduced survival, growth, and health of cutthroat trout fed diets composed of those invertebrates. Colloids and biofilm seem to play a critical role in the pathway of metals into the food chain and concentrations of As, Cu, Pb, and Zn in these two components are significantly correlated. We suggest that transfer of metals associated with Fe colloids to biological components of biofilm is an important pathway where metals associated with abiotic components are first available to biotic components. The significant correlations suggest that Cd, Cu, and Zn may move independently to biota (biofilm, invertebrates, or fish tissues) from water and sediment. The possibility exists that Cd, Cu, and Zn concentrations increase in fish tissues as a result of direct contact with water and sediment and indirect exposure through the food chain. However, uptake through the food chain to fish may be more important for As. Although As concentrations in colloids and biofilm were significantly correlated with As water concentrations, As concentrations in fish tissues were not correlated with water. The pathway for Pb into biological components seems to begin with sediment because concentrations of Pb in water were not significantly correlated with any other component and because concentrations of Pb in the water were often below detection limits.</span></p>","language":"English","publisher":"Springer-Verlag","doi":"10.1007/s00244-005-0021-z","issn":"00904341","usgsCitation":"Farag, A., Nimick, D.A., Kimball, B.A., Church, S.E., Harper, D.D., and Brumbaugh, W.G., 2007, Concentrations of metals in water, sediment, biofilm, benthic macroinvertebrates, and fish in the Boulder River watershed, Montana, and the role of colloids in metal uptake: Archives of Environmental Contamination and Toxicology, v. 52, no. 3, p. 397-409, https://doi.org/10.1007/s00244-005-0021-z.","productDescription":"13 p.","startPage":"397","endPage":"409","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":240625,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213045,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00244-005-0021-z"}],"country":"United States","state":"Montana","otherGeospatial":"Boulder River watershed","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -112.391667,\n              46.425\n            ],\n            [\n              -112.391667,\n              46.35\n            ],\n            [\n              -112.266667,\n              46.241667\n            ],\n            [\n              -112.15,\n              46.241667\n            ],\n            [\n              -112.15,\n              46.425\n            ],\n            [\n              -112.391667,\n              46.425\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"52","issue":"3","noUsgsAuthors":false,"publicationDate":"2007-01-11","publicationStatus":"PW","scienceBaseUri":"5059f996e4b0c8380cd4d6b1","contributors":{"authors":[{"text":"Farag, Aida 0000-0003-4247-6763 aida_farag@usgs.gov","orcid":"https://orcid.org/0000-0003-4247-6763","contributorId":200690,"corporation":false,"usgs":true,"family":"Farag","given":"Aida","email":"aida_farag@usgs.gov","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":425197,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nimick, David A. dnimick@usgs.gov","contributorId":421,"corporation":false,"usgs":true,"family":"Nimick","given":"David","email":"dnimick@usgs.gov","middleInitial":"A.","affiliations":[{"id":573,"text":"Special Applications Science Center","active":true,"usgs":true},{"id":5050,"text":"WY-MT Water Science Center","active":true,"usgs":true}],"preferred":true,"id":425194,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kimball, Briant A. bkimball@usgs.gov","contributorId":533,"corporation":false,"usgs":true,"family":"Kimball","given":"Briant","email":"bkimball@usgs.gov","middleInitial":"A.","affiliations":[{"id":610,"text":"Utah Water Science Center","active":true,"usgs":true}],"preferred":true,"id":425196,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Church, Stanley E. schurch@usgs.gov","contributorId":199165,"corporation":false,"usgs":true,"family":"Church","given":"Stanley","email":"schurch@usgs.gov","middleInitial":"E.","affiliations":[],"preferred":true,"id":425193,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Harper, David D. 0000-0001-7061-8461 david_harper@usgs.gov","orcid":"https://orcid.org/0000-0001-7061-8461","contributorId":1140,"corporation":false,"usgs":true,"family":"Harper","given":"David","email":"david_harper@usgs.gov","middleInitial":"D.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":false,"id":425195,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Brumbaugh, William G. 0000-0003-0081-375X bbrumbaugh@usgs.gov","orcid":"https://orcid.org/0000-0003-0081-375X","contributorId":493,"corporation":false,"usgs":true,"family":"Brumbaugh","given":"William","email":"bbrumbaugh@usgs.gov","middleInitial":"G.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":425198,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Here a novel method is presented that applies spatial analysis software to digital photo-pairs, allowing vegetation change to be categorized and quantified. This method is applied to 12 sites within the alpine treeline ecotone of Glacier National Park, Montana, and is used to examine vegetation changes over timescales ranging from 71 to 93 years. Tree cover at the treeline ecotone increased in 10 out of the 12 photo-pairs (mean increase of 60%). Establishment occurred at all sites, infilling occurred at 11 sites. To demonstrate the utility of this method, patterns of tree establishment at treeline are described and the possible causes of changes within the treeline ecotone are discussed. Local factors undoubtedly affect the magnitude and type of the observed changes, however the ubiquity of the increase in tree cover implies a common forcing mechanism. Mean minimum summer temperatures have increased by 1.5??C over the past century and, coupled with variations in the amount of early spring snow water equivalent, likely account for much of the increase in tree cover at the treeline ecotone. Lastly, shortcomings of this method are presented along with possible solutions and areas for future research. ?? 2007 Regents of the University of Colorado.</p>","language":"English","publisher":"Institute of Arctic and Alpine Research (INSTAAR)","publisherLocation":"Boulder, CO","doi":"10.1657/1523-0430(2007)39[297:DOASAM]2.0.CO;2","issn":"15230430","usgsCitation":"Roush, W., Munroe, J.S., and Fagre, D., 2007, Development of a spatial analysis method using ground-based repeat photography to detect changes in the alpine treeline ecotone, Glacier National Park, Montana, U.S.A.: Arctic, Antarctic, and Alpine Research, v. 39, no. 2, p. 297-308, https://doi.org/10.1657/1523-0430(2007)39[297:DOASAM]2.0.CO;2.","productDescription":"12 p.","startPage":"297","endPage":"308","numberOfPages":"12","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":488075,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1657/1523-0430(2007)39[297:doasam]2.0.co;2","text":"Publisher Index Page"},{"id":240242,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212715,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1657/1523-0430(2007)39[297:DOASAM]2.0.CO;2"}],"country":"United States","state":"Montana","otherGeospatial":"Glacier National Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -116.16943359374999,\n              47.73932336136857\n            ],\n            [\n              -116.16943359374999,\n              49.023461463214126\n            ],\n            [\n              -113.9501953125,\n              49.023461463214126\n            ],\n            [\n              -113.9501953125,\n              47.73932336136857\n            ],\n            [\n              -116.16943359374999,\n              47.73932336136857\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"39","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0044e4b0c8380cd4f695","contributors":{"authors":[{"text":"Roush, W.","contributorId":17887,"corporation":false,"usgs":true,"family":"Roush","given":"W.","email":"","affiliations":[],"preferred":false,"id":424385,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Munroe, Jeffrey S.","contributorId":24175,"corporation":false,"usgs":false,"family":"Munroe","given":"Jeffrey","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":424386,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fagre, D.B.","contributorId":52135,"corporation":false,"usgs":true,"family":"Fagre","given":"D.B.","email":"","affiliations":[],"preferred":false,"id":424387,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In this paper, we first analyze sensitivity of phase velocities of multimodes of surface waves for a six-layer earth model, and then we invert surface-wave dispersion curves of the theoretical model and a real-world example. Sensitivity analysis shows that fundamental mode data are more sensitive to the S-wave velocities of shallow layers and are concentrated on a very narrow frequency band, while higher mode data are more sensitive to the parameters of relatively deeper layers and are distributed over a wider frequency band. These properties provide a foundation of using a multimode joint inversion to define S-wave velocities. Inversion results of both synthetic data and a real-world example demonstrate that joint inversion with the damped least-square method and the singular-value decomposition technique to invert high-frequency surface waves with fundamental and higher mode data simultaneously can effectively reduce the ambiguity and improve the accuracy of S-wave velocities. ?? 2007.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Applied Geophysics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.jappgeo.2007.02.004","issn":"09269851","usgsCitation":"Luo, Y., Xia, J., Liu, J., Liu, Q., and Xu, S., 2007, Joint inversion of high-frequency surface waves with fundamental and higher modes: Journal of Applied Geophysics, v. 62, no. 4, p. 375-384, https://doi.org/10.1016/j.jappgeo.2007.02.004.","startPage":"375","endPage":"384","numberOfPages":"10","costCenters":[],"links":[{"id":239084,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211737,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jappgeo.2007.02.004"}],"volume":"62","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4003e4b0c8380cd649d1","contributors":{"authors":[{"text":"Luo, Y.","contributorId":28417,"corporation":false,"usgs":true,"family":"Luo","given":"Y.","email":"","affiliations":[],"preferred":false,"id":428399,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Xia, J.","contributorId":63513,"corporation":false,"usgs":true,"family":"Xia","given":"J.","email":"","affiliations":[],"preferred":false,"id":428400,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Liu, J.","contributorId":23672,"corporation":false,"usgs":false,"family":"Liu","given":"J.","affiliations":[],"preferred":false,"id":428398,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Liu, Q.","contributorId":17827,"corporation":false,"usgs":true,"family":"Liu","given":"Q.","email":"","affiliations":[],"preferred":false,"id":428397,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Xu, S.","contributorId":84954,"corporation":false,"usgs":true,"family":"Xu","given":"S.","email":"","affiliations":[],"preferred":false,"id":428401,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Examples of cross-scale pattern-process relationships and interactions among forest dieback, fire, and erosion are illustrated from northern New Mexico (USA) landscapes, where long-term studies have recently documented all of these disturbance processes. For example, environmental stress, operating on individual trees, can cause tree death that is amplified by insect mortality agents to propagate to patch and then landscape or even regional-scale forest dieback. Severe drought and unusual warmth in the southwestern USA since the late 1990s apparently exceeded species-specific physiological thresholds for multiple tree species, resulting in substantial vegetation mortality across millions of hectares of woodlands and forests in recent years. Predictions of forest dieback across spatial scales are constrained by uncertainties associated with: limited knowledge of species-specific physiological thresholds; individual and site-specific variation in these mortality thresholds; and positive feedback loops between rapidly-responding insect herbivore populations and their stressed plant hosts, sometimes resulting in nonlinear “pest” outbreak dynamics. Fire behavior also exhibits nonlinearities across spatial scales, illustrated by changes in historic fire regimes where patch-scale grazing disturbance led to regional-scale collapse of surface fire activity and subsequent recent increases in the scale of extreme fire events in New Mexico. Vegetation dieback interacts with fire activity by modifying fuel amounts and configurations at multiple spatial scales. Runoff and erosion processes are also subject to scale-dependent threshold behaviors, exemplified by ecohydrological work in semiarid New Mexico watersheds showing how declines in ground surface cover lead to non-linear increases in bare patch connectivity and thereby accelerated runoff and erosion at hillslope and watershed scales. Vegetation dieback, grazing, and fire can change land surface properties and cross-scale hydrologic connectivities, directly altering ecohydrological patterns of runoff and erosion. The interactions among disturbance processes across spatial scales can be key drivers in ecosystem dynamics, as illustrated by these studies of recent landscape changes in northern New Mexico. To better anticipate and mitigate accelerating human impacts to the planetary ecosystem at all spatial scales, improvements are needed in our conceptual and quantitative understanding of cross-scale interactions among disturbance processes.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s10021-007-9057-4","usgsCitation":"Allen, C.D., 2007, Interactions across spatial scales among forest dieback, fire, and erosion in northern New Mexico landscapes: Ecosystems, v. 10, no. 5, p. 797-808, https://doi.org/10.1007/s10021-007-9057-4.","productDescription":"12 p.","startPage":"797","endPage":"808","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":488068,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://digitalcommons.unl.edu/natrespapers/104","text":"External Repository"},{"id":238928,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"New Mexico","volume":"10","issue":"5","noUsgsAuthors":false,"publicationDate":"2007-06-20","publicationStatus":"PW","scienceBaseUri":"505a3cbce4b0c8380cd62fbc","contributors":{"authors":[{"text":"Allen, Craig D. 0000-0002-8777-5989 craig_allen@usgs.gov","orcid":"https://orcid.org/0000-0002-8777-5989","contributorId":2597,"corporation":false,"usgs":true,"family":"Allen","given":"Craig","email":"craig_allen@usgs.gov","middleInitial":"D.","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":428918,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

From May 1999-January 2002, we flew 102 d, covered >54,640 km of transect lines, and conducted nine complete surveys of southern California in January, May, and September. We identified 54 species comprising 12 families and counted >135,000 individuals. Seabird densities were greater along island and mainland coastlines than at sea and were usually greatest in January surveys. Densities were greatest at sea near the northern Channel Islands in January and north of Point Conception in May, and lowest in the southwestern portion of the Southern California Bight in all survey months. On coastal transects, seabird densities were greatest along central and southern portions of the mainland coastline from Point Arguello to Mexico. We estimated that 981,000 ?? 144,000 (x?? ?? SE) seabirds occurred in the study area in January, 862,000 ?? 95,000 in May, and 762,000 ?? 72,000 in September. California Gulls (Larus californicus), Western Grebes (Aechmophorus occidentalis), and Cassin's Auklets (Ptychoramphus aleuticus) were most abundant in January surveys at sea, whereas Sooty and Short-tailed shearwaters (Puffinus griseus and P. tenuirostris), phalaropes (Phalaropus spp.), and Western Gulls (Larus. occidentalis) were most abundant in May and September surveys. On coastal transects, California Gulls, Western Grebes, Western Gulls, and Surf Scoters (Melanitta perspicillata) were most abundant in January; Western Grebes, Western Gulls, Surf Scoters, and Brown Pelicans (Pelecanus occidentalis) were most abundant in May; and Sooty Shearwaters, Short-tailed Shearwaters, Western Gulls, Western Grebes, Brown Pelicans, and Heermann's Gulls (Larus heermanni) were most abundant in September. Compared to historical seabird densities collected in the same area two decades ago (1975-1978 and 1980-1983), abundance was lower by 14% in January, 57% in May, and 42% in September. Common Murres (Uria aalge, ???75% in each season), Sooty Shearwaters (55% in May, 27% in September), and Bonaparte's Gulls (L. Philadelphia, ???95% in each season) had lower densities. Conversely, Brown Pelicans (167% overall), Xantus's Murrelets (Synthliboramphus hypoleucus; 125% overall), Cassin's Auklets (100% overall), Ashy Storm-Petrels (Oceanodroma homochroa, 450% overall) and Western Gulls (55% in May), and Brandt's Cormorants (Phalacrocorax penicillatus, 450% in September) had greater densities. Our results indicate that seabird abundance has declined off the southern California coast in the past two decades, and these declines may be warning signs of environmental degradation in the region or effects of larger forces such as climate change.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Studies in Avian Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"01979922","isbn":"0943610729; 9780943610726","usgsCitation":"Mason, J., McChesney, G., McIver, W., Carter, H., Takekawa, J.Y., Golightly, R., Ackerman, J., Orthmeyer, D., Perry, W., Yee, J., Pierson, M., and McCrary, M., 2007, At-sea distribution and abundance of seabirds off southern California: A 20-year comparison: Studies in Avian Biology, no. 33, p. 1-101.","startPage":"1","endPage":"101","numberOfPages":"101","costCenters":[],"links":[{"id":240447,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"33","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ee9ce4b0c8380cd49e6c","contributors":{"authors":[{"text":"Mason, J.W.","contributorId":79433,"corporation":false,"usgs":true,"family":"Mason","given":"J.W.","email":"","affiliations":[],"preferred":false,"id":424075,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McChesney, G.J.","contributorId":20936,"corporation":false,"usgs":true,"family":"McChesney","given":"G.J.","email":"","affiliations":[],"preferred":false,"id":424070,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McIver, W.R.","contributorId":21907,"corporation":false,"usgs":true,"family":"McIver","given":"W.R.","email":"","affiliations":[],"preferred":false,"id":424071,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Carter, H.R.","contributorId":20680,"corporation":false,"usgs":false,"family":"Carter","given":"H.R.","email":"","affiliations":[{"id":34154,"text":"Point Reyes Bird Observatory, Stinson Beach, CA","active":true,"usgs":false}],"preferred":false,"id":424069,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"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":424074,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Golightly, R.T.","contributorId":10743,"corporation":false,"usgs":true,"family":"Golightly","given":"R.T.","email":"","affiliations":[],"preferred":false,"id":424067,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Ackerman, Joshua T. 0000-0002-3074-8322 jackerman@usgs.gov","orcid":"https://orcid.org/0000-0002-3074-8322","contributorId":147078,"corporation":false,"usgs":true,"family":"Ackerman","given":"Joshua T.","email":"jackerman@usgs.gov","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":424077,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Orthmeyer, D.L.","contributorId":84684,"corporation":false,"usgs":true,"family":"Orthmeyer","given":"D.L.","email":"","affiliations":[],"preferred":false,"id":424076,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Perry, W.M.","contributorId":15949,"corporation":false,"usgs":true,"family":"Perry","given":"W.M.","affiliations":[],"preferred":false,"id":424068,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Yee, J.L.","contributorId":25496,"corporation":false,"usgs":true,"family":"Yee","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":424072,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Pierson, M.O.","contributorId":96555,"corporation":false,"usgs":true,"family":"Pierson","given":"M.O.","email":"","affiliations":[],"preferred":false,"id":424078,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"McCrary, M.D.","contributorId":52850,"corporation":false,"usgs":true,"family":"McCrary","given":"M.D.","email":"","affiliations":[],"preferred":false,"id":424073,"contributorType":{"id":1,"text":"Authors"},"rank":12}]}}

The ranges of sulfur and oxygen isotope values in aqueous sulfate, ??34S[SO4] and ??18O[SO4], at the Kelly's Cove watershed are + 3.4 to + 4.9??? and - 2.0 to + 6.7???, respectively. These isotope values are strikingly similar to those of the Goose River, Maine watershed which has ??34S[SO4] and ??18O[SO4] ranges of + 3.7 to + 4.6 ??? and - 2.6 to + 7.5???, respectively. In both systems, high arsenic concentrations occur with high ??34S[SO4] and ??18O[SO4] values, yet redox conditions and underlying rock types are quite different. The isotope values of sulfide minerals, ??34S[min], from four bedrock cores vary over short distances and range from - 5.1 to + 7.5???. The ??34S[SO4] values are controlled by the ??34S[min] values with minor input of atmospheric SO4. The much narrower range in ??34S[SO4] values than ??34S[min] values is probably due to sufficient ground-water mixing at a scale greater than the ??34S[min] variability. The ??34S[SO4] values are about 2??? higher than the average ??34S[min] value and fall within the range of ??34S[min] values, indicating only minor fractionation due to bacterial reduction of SO4. The highest ??18O[SO4] values were measured in the downgradient, confined, arsenic-rich ground water. High ??18O[SO4] values there cannot be due to aeration by atmospheric oxygen, but may arise from reoxidation of reduced SO4 products. The enrichment factors of ??18O in SO4 compared to H2O, + 7.2 to + 15.5???, in the Kelly's Cove ground water and the negligible 34S enrichment is very similar to those derived from experimental data of anaerobic sulfide oxidation in the presence of Mn and Fe oxides. Sea level at the Kelly's Cove watershed was approximately 80??m above present sea level about 13 000??years before present, imposing reducing conditions on that area of the watershed. Sea level dropped approximately 60??m below present sea level about 11 000??years before present, allowing for possible oxidation of sulfide minerals and precipitation of arsenic in ferric oxyhydroxides during aeration of the ground-water system. Under present redox conditions, there is evidence that bacteria reduction of ferric oxyhydroxides releases arsenic. The fractionation of 18O in the SO4 during anaerobic oxidation of sulfide in the presence of Mn and Fe oxides and subsequent release of arsenic during Mn and Fe oxide reduction may explain the relationship between high arsenic concentrations and elevated 18O[SO4] at Kelly's Cove. ?? 2007 Elsevier B.V.

Arizona’s Biocriteria index was developed using a riffle habitat sampling methodology, whereas the EMAP method employs a multi-habitat sampling protocol. There was a need to demonstrate comparability of these different bioassessment methodologies to allow use of the EMAP multi-habitat protocol for both statewide probabilistic assessments for integration of the EMAP data into the national (305b) assessment and for targeted in-state bioassessments for 303d determinations of standards violations and impaired aquatic life conditions. The purpose of this study was to evaluate whether the two methods yield similar bioassessment results, such that the data could be used interchangeably in water quality assessments. In this Regional EMAP grant funded project, a probabilistic survey of 30 sites in the Little Colorado River basin was conducted in the spring of 2007. Macroinvertebrate and habitat data were collected using both ADEQ and EMAP sampling methods, from adjacent reaches within these stream channels.</p><p>All analyses indicated that the two macroinvertebrate sampling methods were significantly correlated. ADEQ and EMAP samples were classified into the same scoring categories (meeting, inconclusive, violating the biocriteria standard) 82% of the time. When the ADEQ-IBI was applied to both the ADEQ and EMAP taxa lists, the resulting IBI scores were significantly correlated (r=0.91), even though only 4 of the 7 metrics in the IBI were significantly correlated. The IBI scores from both methods were significantly correlated to the percent of riffle habitat, even though the average percent riffle habitat was only 30% of the stream reach. Multivariate analyses found that the percent riffle was an important attribute for both datasets in classifying IBI scores into assessment categories.</p><p>Habitat measurements generated from EMAP and ADEQ methods were also significantly correlated; 13 of 16 habitat measures were significantly correlated (p&lt;0.01). The visual-based percentage estimates of percent riffle and pool habitats, vegetative cover and percent canopy cover, and substrate measurements of percent fine substrate and embeddedness were all remarkably similar, given the different field methods used. A multivariate analysis identified substrate and flow conditions, as well as canopy cover as important combinations of habitat attributes affecting both IBI scores. These results indicate that similar habitat measures can be obtained using two different field sampling protocols. In addition, similar combinations of these habitat parameters were important to macroinvertebrate community condition in multivariate analyses of both ADEQ and EMAP datasets.</p><p>These results indicate the two sampling methods for macroinvertebrates and habitat data were very similar in terms of bioassessment results and stressors. While the bioassessment category was not identical for all sites, overall the assessments were significantly correlated, providing similar bioassessment results for the cold water streams used in this study. The findings of this study indicate that ADEQ can utilize either a riffle-based sampling methodology or a multi-habitat sampling approach in cold water streams as both yield similar results relative to the macroinvertebrate assemblage. These results will allow for use of either macroinvertebrate dataset to determine water quality standards compliance with the ADEQ Indexes of Biological Integrity, for which threshold values were just recently placed into the Arizona Surface Water Quality Standards. While this survey did not include warm water desert streams of Arizona, we would predict that EMAP and ADEQ sampling methodologies would provide similar bioassessment results and would not be significantly different, as we have found that the percent riffle habitat in cold and warm water perennial, wadeable streams is not significantly different. However, a comparison study of sampling methodologies in warm water streams should be conducted to confirm the predicted similarity of bioassessment results. ADEQ will continue to implement a monitoring strategy that includes probabilistic monitoring for a statewide ecological assessment of stream conditions. Conclusions from this study will guide decisions regarding the most appropriate sampling methods for future probabilistic monitoring sample plans.</p>","language":"English","publisher":"Arizona Department of Environmental Quality","usgsCitation":"Spindler, P., and Paretti, N.V., 2007, A comparison of macroinvertebrate and habitat methods of data collection in the Little Colorado River Watershed, Arizona 2007: Open-File Report 10-05, 44 p.","productDescription":"44 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":128,"text":"Arizona Water Science Center","active":true,"usgs":true}],"links":[{"id":409294,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://azdeq.gov/surface-water-reports"},{"id":306884,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arizona","otherGeospatial":"Little Colorado River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -109.05225085860557,\n              33.997147907235785\n            ],\n            [\n              -109.04106100464412,\n              35.15461273818636\n            ],\n            [\n              -112.02896638603738,\n              35.17081103556828\n            ],\n            [\n              -112.02896638603738,\n              35.05951329223615\n            ],\n            [\n              -112.18135500293924,\n              35.01940890226042\n            ],\n            [\n              -112.11604559569567,\n              34.930217592804965\n            ],\n            [\n              -112.18135500293924,\n              34.76942868845617\n            ],\n            [\n              -112.14325784871377,\n              34.675490175745026\n            ],\n            [\n              -111.83303816430666,\n              34.39303515518253\n            ],\n            [\n              -111.75684385585603,\n              34.410997280051035\n            ],\n            [\n              -111.55003073291795,\n              34.42895554846932\n            ],\n            [\n              -111.37587231360197,\n              34.35709933984734\n            ],\n            [\n              -111.29423555454736,\n              34.42446634295791\n            ],\n            [\n              -111.14728938824946,\n              34.384052646872874\n            ],\n            [\n              -110.91870646289696,\n              34.29417457634274\n            ],\n            [\n              -110.74454804358068,\n              34.177189196638395\n            ],\n            [\n              -110.5921594266791,\n              34.16818359070621\n            ],\n            [\n              -110.37990385313734,\n              34.01494136859705\n            ],\n            [\n              -110.3418066989122,\n              33.8885337937307\n            ],\n            [\n              -110.17309073019959,\n              33.90660351226566\n            ],\n            [\n              -109.83565879277435,\n              33.94273145971013\n            ],\n            [\n              -109.69959752768384,\n              33.93821630426183\n            ],\n            [\n              -109.5689787131967,\n              33.96078968665205\n            ],\n            [\n              -109.53632400957491,\n              33.59889828847642\n            ],\n            [\n              -109.3896827960308,\n              33.56287969227705\n            ],\n            [\n              -109.2155243767145,\n              33.71693475565631\n            ],\n            [\n              -109.18286967309271,\n              33.93395436276049\n            ],\n            [\n              -109.05225085860557,\n              33.997147907235785\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57fe8b41e4b0824b2d14a9d8","contributors":{"authors":[{"text":"Spindler, Patrice","contributorId":146624,"corporation":false,"usgs":false,"family":"Spindler","given":"Patrice","email":"","affiliations":[],"preferred":false,"id":568470,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Paretti, Nick V.","contributorId":146625,"corporation":false,"usgs":false,"family":"Paretti","given":"Nick","email":"","middleInitial":"V.","affiliations":[],"preferred":false,"id":568471,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Few studies were found that addressed hydrological effects of roads on a comparable area of shallow slope in a semiarid region. No study dealt with road effects on surface- and ground-water supplies to ephemeral wetlands, which on the refuge are sustained by seasonal snowmelt in neighboring mountains. Road surfaces increase runoff, reduce infiltration, and serve as a sediment source. Roadbeds can interfere with normal surface- and ground-water flows and thereby influence the quantity, timing, and duration of water movement both across landscapes and through the soil. Hydrologic effects can be localized near the road as well as widespread and distant. The number, arrangement, and effectiveness of road-drainage structures (culverts and other devices) largely determine the level of hydrologic alteration produced by a road. Undesirable changes to natural hydrologic patterns can be minimized by considering potential impacts during road design, construction, and maintenance. Road removal as a means to restore desirable hydrologic conditions to landscapes adversely affected by roads has yet to be rigorously evaluated.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20071052","collaboration":"Prepared in cooperation with the U.S. Fish and Wildlife Service","usgsCitation":"Andersen, D., 2007, Road impacts on the Baca National Wildlife Refuge, Colorado, with emphasis on effects to surface- and shallow ground-water hydrology - A literature review: U.S. Geological Survey Open-File Report 2007-1052, v, 26 p., https://doi.org/10.3133/ofr20071052.","productDescription":"v, 26 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":192460,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20071052.PNG"},{"id":320218,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2007/1052/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Colorado","otherGeospatial":"Baca National Wildlife Refuge","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b28e4b07f02db6b1614","contributors":{"authors":[{"text":"Andersen, Douglas C. doug_andersen@usgs.gov","contributorId":2216,"corporation":false,"usgs":true,"family":"Andersen","given":"Douglas C.","email":"doug_andersen@usgs.gov","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":291874,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Our objectives were to inform future monitoring and management at the site, and to elucidate poorly known aspects of the species’ population ecology. Movement rates revealed complementary use of sites seasonally, with one small spring being preferred during winter that was rarely used during the rest of the year. Growth rates were significantly higher in ponds that were not used for breeding, and larger size resulted in significantly higher survival. When variation in survival by size was accounted for there was little variation among ponds in survival. Seasonal estimates of survival were lowest for males during the breeding/post-breeding redistribution period, suggesting a high cost of breeding for males. Overwintering survival for both genders was relatively high. Our study supports others in suggesting Oregon spotted frogs are specific in their overwintering habitat requirements, and that predator-free springs may be of particular value. We suggest that any future monitoring include measures of the rate of pond succession. Demographic monitoring should include metrics of both frog reproduction and survival: counts of egg masses at all ponds during spring, and capture-recapture study of survival in mid and late summer when capture rates are highest. Additional study of early life stages would be particularly useful to broaden our understanding of the species’ ecology. Specifically, adding intensive capture and marking effort after larval transformation in fall would enable a full understanding of the annual life cycle. Complete study of the annual life cycle is needed to isolate the life stages and mechanisms through which Oregon spotted frogs are affected by stressors such as nonnative predators. Dilman Meadow, which lacks many hypothesized stressors, is an important reference for isolating the life stages most responsive to management elsewhere in the species’ range.</span></p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20071016","collaboration":"Prepared in cooperation with the Sunriver Nature Center","usgsCitation":"Chelgren, N.D., Pearl, C., Bowerman, J., and Adams, M.J., 2007, Oregon Spotted Frog (Rana pretiosa) movement and demography at Dilman Meadow: Implications for future monitoring: U.S. Geological Survey Open-File Report 2007-1016, 27 p., https://doi.org/10.3133/ofr20071016.","productDescription":"27 p.","numberOfPages":"27","onlineOnly":"Y","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":10024,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2007/1016/","linkFileType":{"id":5,"text":"html"}},{"id":9972,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2007/1016/pdf/ofr20071016.pdf","text":"Report","size":"1.2 KB","linkFileType":{"id":1,"text":"pdf"},"description":"OFR 2007-1016"},{"id":194829,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2007/1016/coverthb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aeee4b07f02db691246","contributors":{"authors":[{"text":"Chelgren, Nathan D.","contributorId":49062,"corporation":false,"usgs":true,"family":"Chelgren","given":"Nathan","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":291881,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pearl, Christopher A. 0000-0003-2943-7321","orcid":"https://orcid.org/0000-0003-2943-7321","contributorId":84316,"corporation":false,"usgs":true,"family":"Pearl","given":"Christopher A.","affiliations":[{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true}],"preferred":false,"id":291883,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bowerman, Jay","contributorId":57024,"corporation":false,"usgs":false,"family":"Bowerman","given":"Jay","email":"","affiliations":[],"preferred":false,"id":291882,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Adams, M.

Submarine confining units produce semi-confined offshore aquifers that are recharged on shore. These low-permeability deposits are usually either late Pleistocene to Holocene in age, or date to the period of the last interglacial highstand. Extensive confining units consisting of peat form in tropical mangrove swamps, and in salt marshes and freshwater marshes and swamps at mid-latitudes. At higher latitudes, fine-grained glaciomarine sediments are widespread. The net effect of these shallow confining units is that groundwater from land often flows farther offshore before discharging than would normally be expected. In many settings, the presence of such confining units is critical to determining how and where pollutants from land will be discharged into coastal waters. Alternatively, these confining units may also protect fresh groundwater supplies from saltwater intrusion into coastal wells.","largerWorkTitle":"IAHS-AISH Publication","conferenceTitle":"International Symposium: A New Focus on Groundwater - Seawater Interactions - 24th General Assembly of the In","conferenceDate":"2 July 2007 through 13 July 2007","conferenceLocation":"Perugia","language":"English","issn":"01447","isbn":"9781901502046","usgsCitation":"Bratton, J., 2007, The importance of shallow confining units to submarine groundwater flow, <i>in</i> IAHS-AISH Publication, no. 312, Perugia, 2 July 2007 through 13 July 2007, p. 28-36.","productDescription":"9 p.","startPage":"28","endPage":"36","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":241988,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"312","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bacfde4b08c986b3238d4","contributors":{"authors":[{"text":"Bratton, J.F.","contributorId":94354,"corporation":false,"usgs":true,"family":"Bratton","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":441775,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
