However, these data are unable to determine whether these movements contribute to gene flow among adjacent breeding areas. We used eight microsatellite DNA loci and mitochondrial DNA control-region sequence data to assess population structure of Northern Goshawks breeding in Utah. Goshawks had moderate levels of genetic variation at microsatellite loci (observed heterozygosity = 50%), similar to levels found in other medium-sized, highly mobile birds. Overall estimates of interpopulation variance in microsatellite alleles (<i>F<sub>ST</sub></i><span>&nbsp;= 0.011</span>) and mtDNA haplotypes (<span>Φ</span><sub><i>ST</i></sub><span>&nbsp;= 0.126</span>) were low and not significantly different from zero. Pairwise population comparisons using microsatellite markers revealed no differentiation among sampled sites, indicating that the functional population extends beyond Utah. However, pairwise population analyses of mtDNA uncovered a single case of differentiation between goshawks inhabiting Ashley National Forest, in northeastern Utah, and Dixie National Forest, in southwestern Utah. Low levels of population structuring observed in mtDNA between the two forests may be due to the smaller effective population size sampled by mtDNA, a cline of haplotypes across the West, or the presence of a contact zone between <i>A. g. atricapillus</i> and goshawks of southern Arizona and the Mexican Plateau.</p>","language":"English","publisher":"Oxford Academic","doi":"10.1650/7448","usgsCitation":"Sonsthagen, S.A., Talbot, S.L., and White, C., 2004, Gene flow and genetic characterization of Northern Goshawks breeding in Utah: Condor, v. 106, no. 4, p. 826-836, https://doi.org/10.1650/7448.","productDescription":"11 p.","startPage":"826","endPage":"836","costCenters":[{"id":463,"text":"Nebraska Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":478250,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1650/7448","text":"Publisher Index Page"},{"id":234373,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Utah","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -114.169921875,\n              36.914764288955936\n            ],\n            [\n              -108.984375,\n              36.914764288955936\n            ],\n            [\n              -109.0283203125,\n              40.94671366508002\n            ],\n            [\n              -110.91796875,\n              40.94671366508002\n            ],\n            [\n              -110.9619140625,\n              42.00032514831621\n            ],\n            [\n              -114.169921875,\n              42.032974332441405\n            ],\n            [\n              -114.169921875,\n              36.914764288955936\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"106","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a14f9e4b0c8380cd54c55","contributors":{"authors":[{"text":"Sonsthagen, Sarah A. 0000-0001-6215-5874 ssonsthagen@usgs.gov","orcid":"https://orcid.org/0000-0001-6215-5874","contributorId":3711,"corporation":false,"usgs":true,"family":"Sonsthagen","given":"Sarah","email":"ssonsthagen@usgs.gov","middleInitial":"A.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":409547,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Talbot, Sandra L. 0000-0002-3312-7214 stalbot@usgs.gov","orcid":"https://orcid.org/0000-0002-3312-7214","contributorId":140512,"corporation":false,"usgs":true,"family":"Talbot","given":"Sandra","email":"stalbot@usgs.gov","middleInitial":"L.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":409546,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"White, C.M.","contributorId":97459,"corporation":false,"usgs":true,"family":"White","given":"C.M.","email":"","affiliations":[],"preferred":false,"id":409548,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

If nutrient acquisition is habitat-specific, then selection and use of habitats may differ between these reproductive stages. A better understanding of these processes is needed to assist future habitat conservation and management efforts. In January-May 1999 and 2000, we monitored movements and habitat use of radiomarked females (n = 47) during the prelaying and egg-production periods of first nests. Home-range size averaged 367 ha and did not vary with reproductive period, year, or female age. Habitat use did not differ between periods of prelaying and egg production; consequently, data were combined. Habitat use varied between years, female age, and periods of nest initiation (i.e., early vs. late). Use of beaver ponds (BP), temporary wetlands (TW), managed impoundments (MI), and lake habitats (LK) declined in 2000 compared to 1999, possibly due to reduced precipitation. Nest initiation date was independent of female age. Adult females used BP more than yearlings, and early-nesting females used BP and MI more than late-nesting females. Females selected habitats nonrandomly when habitat composition of the study area was compared to that of home ranges (second-order selection). Lake-influenced wetlands (LI) and MI were ranked highest in preference. Home-range size was inversely related to percentage of the home range comprised of MI and LI, supporting the idea that MI and LI were high-quality habitats. However, we found no relationship between nest initiation date (an important index to reproductive performance) and the combined area of MI and LI in home ranges. Habitai selection did not differ from random when habitat composition of home ranges was compared to that of radio locations (third-order selection). Although MI and LI were preferred, high-quality habitats, our results suggest that breeding female wood ducks can satisfy requirements for egg production using a variety of wetland habitats. We suggest that providing a diversity of habitat types will increase the probability of meeting needs of breeding females throughout the breeding season, especially in areas where wetland conditions frequently change.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/0022-541X(2004)068[0084:HUAPOB]2.0.CO;2","issn":"0022541X","usgsCitation":"Hartke, K.M., and Hepp, G.R., 2004, Habitat use and preferences of breeding female wood ducks: Journal of Wildlife Management, v. 68, no. 1, p. 84-93, https://doi.org/10.2193/0022-541X(2004)068[0084:HUAPOB]2.0.CO;2.","startPage":"84","endPage":"93","numberOfPages":"10","costCenters":[],"links":[{"id":211229,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/0022-541X(2004)068[0084:HUAPOB]2.0.CO;2"},{"id":238463,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"68","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2f36e4b0c8380cd5cbb9","contributors":{"authors":[{"text":"Hartke, Kevin M.","contributorId":84048,"corporation":false,"usgs":true,"family":"Hartke","given":"Kevin","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":414839,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hepp, Gary R.","contributorId":8191,"corporation":false,"usgs":true,"family":"Hepp","given":"Gary","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":414838,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The photometric as well as textural differences between these regions can be explained in terms of topography (roughness) at and below the&nbsp;image resolution, without invoking significant variations in single-particle properties; the material on Borrelly's surface could be quite uniform. A statistical comparison of the digital elevation models (DEMs) produced from the three&nbsp;highest-resolution&nbsp;images independently at the USGS and DLR shows that their difference standard deviation is 120 m, consistent with a matching error of 0.20 pixel (similar to reported matching accuracies for many other stereo datasets).

Many local radiance variations are clearly related to topography, and others are consistent with a topographic explanation; one need not invoke albedo variations greater than a few tens of percent to explain the appearance of Borrelly.</span></p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Icarus","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.icarus.2003.07.009","issn":"00191035","usgsCitation":"Kirk, R.L., Howington-Kraus, E., Soderblom, L.A., Giese, B., and Oberst, J., 2004, Comparison of USGS and DLR topographic models of Comet Borrelly and photometric applications: Icarus, v. 167, no. 1, p. 54-69, https://doi.org/10.1016/j.icarus.2003.07.009.","productDescription":"16 p.","startPage":"54","endPage":"69","numberOfPages":"16","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":238355,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Comet Borrelly","volume":"167","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f849e4b0c8380cd4cfc7","contributors":{"authors":[{"text":"Kirk, Randolph L. 0000-0003-0842-9226 rkirk@usgs.gov","orcid":"https://orcid.org/0000-0003-0842-9226","contributorId":2765,"corporation":false,"usgs":true,"family":"Kirk","given":"Randolph","email":"rkirk@usgs.gov","middleInitial":"L.","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":415169,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Howington-Kraus, Elpitha 0000-0001-5787-6554 ahowington@usgs.gov","orcid":"https://orcid.org/0000-0001-5787-6554","contributorId":2815,"corporation":false,"usgs":true,"family":"Howington-Kraus","given":"Elpitha","email":"ahowington@usgs.gov","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":415168,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Soderblom, Laurence A. 0000-0002-0917-853X lsoderblom@usgs.gov","orcid":"https://orcid.org/0000-0002-0917-853X","contributorId":2721,"corporation":false,"usgs":true,"family":"Soderblom","given":"Laurence","email":"lsoderblom@usgs.gov","middleInitial":"A.","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":415166,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Giese, Bernd","contributorId":211337,"corporation":false,"usgs":false,"family":"Giese","given":"Bernd","email":"","affiliations":[],"preferred":false,"id":415167,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Oberst, Jurgen","contributorId":147983,"corporation":false,"usgs":false,"family":"Oberst","given":"Jurgen","email":"","affiliations":[],"preferred":false,"id":415170,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

In North America, the grizzly bear (Ursus arctos) once ranged from Mexico northward to Alaska, however its range in the continental USA has been reduced by 95-98%. Under the U. S. Endangered Species Act, the Yellowstone grizzly bear population has re-colonised habitats outside Yellowstone National Park. We analysed historical and current records, including data on radio-collared bears, (1) to evaluate changes in grizzly bear distribution in the southern Greater Yellowstone Ecosystem (GYE) over a 100-year period, (2) to utilise historical rates of re-colonisation to project future expansion trends and (3) to evaluate the reality of future expansion based on human limitations and land use. Analysis of distribution in 20-year increments reflects range reduction from south to north (1900-1940) and expansion to the south (1940-2000). Expansion was exponential and the area occupied by grizzly bears doubled approximately every 20 years. A complementary analysis of bear occurrence in Grand Teton National Park also suggests an unprecedented period of rapid expansion during the last 20-30 years. The grizzly bear population currently has re-occupied about 50% of the southern GYE. Based on assumptions of continued protection and ecological stasis, our model suggests total occupancy in 25 years. Alternatively, extrapolation of linear expansion rates from the period prior to protection suggests total occupancy could take &gt; 100 years. Analyses of historical trends can be useful as a restoration tool because they enable a framework and timeline to be constructed to pre-emptively address the social challenges affecting future carnivore recovery. ?? 2004 The Zoological Society of London.</p>","language":"English","publisher":"Zoological Society of London","publisherLocation":"United

This method requires only 70 nmol of NO3- and enables high throughput of samples. We studied nitrate sources to a headwater stream during snowmelt by generating a high-temporal resolution dataset at the Sleepers River Research Watershed in Vermont, USA. In the earliest phase of runoff, stream NO3- concentrations were highest and stream discharge, NO3- concentrations, and ??18O of NO 3- generally tracked one another during diurnal melting. The isotopic composition of stream NO3- varied in-between atmospheric and groundwater NO 3- end members indicating a direct contribution of atmospherically-derived NO3- from the snow pack to the stream. During the middle to late phases of snowmelt, the source shifted toward soil NO3- entering the stream via shallow subsurface flow paths.

We analyzed one hundred nineteen 1-cm-thick samples for pollen and algae from a set of cores that span the past 7630 years. The early middle Holocene, 7600 to 6300 cal yr B.P., was found to be the driest period, although it included one short but intense wet phase. We suggest that Lake Tahoe was below its rim for most of this period, greatly reducing the volume and depth of Pyramid Lake. Middle Holocene aridity eased between 5000 and 3500 cal yr B.P. and climate became variable with distinct wet and dry phases. Lake Tahoe probably spilled intermittently during this time. No core was recovered that represented the period between 3500 and 2600 cal yr B.P. The past 2500 years appear to have had recurrent persistent droughts. The timing and magnitude of droughts identified in the pollen record compares favorably with previously published ??18O data from Pyramid Lake. The timing of these droughts also agrees with the ages of submerged rooted stumps in the Eastern Sierra Nevada and woodrat midden data from central Nevada. Prolonged drought episodes appear to correspond with the timing of ice drift minima (solar maxima) identified from North Atlantic marine sediments, suggesting that changes in solar irradiance may be a possible mechanism influencing century-scale drought in the western Great Basin. ?? 2004 University of Washington.

However, a number of examples showed that random noise in adjacent traces exhibits correlation and coherence. The average stacking and weighted stacking based on the conventional correlative function all result in false events, which are caused by noise. Wavelet transform and high order statistics are very useful methods for modern signal processing. The multiresolution analysis in wavelet theory can decompose signal on difference scales, and high order correlative function can inhibit correlative noise, for which the conventional correlative function is of no use. Based on the theory of wavelet transform and high order statistics, high order correlative weighted stacking (HOCWS) technique is presented in this paper. Its essence is to stack common midpoint gathers after the normal moveout correction by weight that is calculated through high order correlative statistics in the wavelet domain. Synthetic examples demonstrate its advantages in improving the signal to noise (S/N) ration and compressing the correlative random noise.","largerWorkTitle":"Progress in Environmental and Engineering Geophysics: Proceedings of the International Conference on Environmental and Engineering Geophysics, ICEEG 2004","conferenceTitle":"Progress in Environmental and Engineering Geophysics: Proceedings of the International Conference on Environmental and Engineering Geophysics, ICEEG 2004","conferenceDate":"6 June 2004 through 9 June 2004","conferenceLocation":"Wuhan","language":"English","isbn":"1880132974","usgsCitation":"Zhang, S., Xu, Y., and Xia, J., 2004, Correlative weighted stacking for seismic data in the wavelet domain, <i>in</i> Progress in Environmental and Engineering Geophysics: Proceedings of the International Conference on Environmental and Engineering Geophysics, ICEEG 2004, Wuhan, 6 June 2004 through 9 June 2004, p. 161-165.","startPage":"161","endPage":"165","numberOfPages":"5","costCenters":[],"links":[{"id":233936,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fc52e4b0c8380cd4e217","contributors":{"editors":[{"text":"Chen C.Xia J.","contributorId":128353,"corporation":true,"usgs":false,"organization":"Chen C.Xia J.","id":536599,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Zhang, S.","contributorId":51064,"corporation":false,"usgs":true,"family":"Zhang","given":"S.","email":"","affiliations":[],"preferred":false,"id":409276,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Xu, Y.","contributorId":47816,"corporation":false,"usgs":true,"family":"Xu","given":"Y.","email":"","affiliations":[],"preferred":false,"id":409275,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Xia, J.","contributorId":63513,"corporation":false,"usgs":true,"family":"Xia","given":"J.","email":"","affiliations":[],"preferred":false,"id":409277,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

When using 9 microsatellite DNA loci, observed heterozygosity was similar among populations (HO = 0.49-0.59) and intermediate to that of other large carnivores. Estimates of genetic structure (FST = 0.028, RST = 0.029) and number of migrants per generation (Nm) suggested high gene flow. Nm was lowest between distant populations and highest among adjacent populations. Examination of these data, plus Mantel test results of genetic versus geographic distance (P ??? 0.01), suggested both isolation by distance and an effect of habitat matrix. Bayesian assignment to population based on individual genotypes showed that cougars in this region were best described as a single panmictic population. Total effective population size for cougars in this region ranged from 1,797 to 4,532 depending on mutation model and analytical method used. Based on measures of gene flow, extinction risk in the near future appears low. We found no support for the existence of metapopulation structure among cougars in this region.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Mammalogy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1644/BEL-111.1","issn":"00222372","usgsCitation":"Anderson, C., Lindzey, F., and McDonald, D., 2004, Genetic structure of cougar populations across the Wyoming basin: Metapopulation or megapopulation: Journal of Mammalogy, v. 85, no. 6, p. 1207-1214, https://doi.org/10.1644/BEL-111.1.","startPage":"1207","endPage":"1214","numberOfPages":"8","costCenters":[],"links":[{"id":208552,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1644/BEL-111.1"},{"id":234368,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"85","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1585e4b0c8380cd54e5e","contributors":{"authors":[{"text":"Anderson, C.R.

The upper SFE includes the tidal freshwater areas of the Sacramento-San Joaquin Delta downstream to the euryhaline environment of San Pablo Bay. The sampling period included years with a variety of outflow conditions. Fifty taxa were collected using a larval tow net. Two common native species, delta smelt Hypomesus transpacifucus and longfin smelt Spirinchus thaleichthys, and four common alien taxa, striped bass Morone saxatilis, threadfin shad Dorosoma petenense, gobies of the genus Tridentiger, and yellowfin goby Acanthogobins flavimanus, were selected for detailed analysis. Outflow conditions had a strong influence on the geographic distribution of most of the species, but distribution with respect to the 2 psu isohaline (X2) was not affected. The distribution patterns of delta smelt, longfin smelt, and striped bass were consistent with larvae moving from upstream freshwater spawning areas to down-stream estuarine rearing areas. There were no obvious relationships of outflow with annual abundance indices. Our results support the idea of using X2 as an organizing principle in understanding the ecology of larval fishes in the upper SFE. Additional years of sampling will likely lead to additional insights into the early life history of upper SFE fishes. ??

Understanding the relationships between water-quality parameters and copper toxicity may facilitate the development of site-specific criteria for water quality and result in better protection of aquatic biota. Many studies have examined the influence of a single water-quality parameter on copper toxicity, but the interactions of several characteristics have not been well studied in low-hardness water. The goal of the present research was to examine the interactions among water-quality characteristics and their effects on copper toxicity to larval fathead minnows (Pimephales promelas). The effects of dissolved organic carbon (DOC) concentration, DOC source, pH, and hardness on acute copper toxicity were determined using a complete factorially designed experiment. Hardness, pH, DOC, and interaction of pH and DOC all significantly affected copper toxicity. A predictive model based on these data described 88% of the variability in copper toxicity. This model also explained 58% of the variability in copper toxicity for an independent dataset of South Carolina (USA) waters. The biotic ligand model underpredicted the acute copper toxicity to fathead minnows when compared with observed values.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Toxicology and Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1897/03-574.1","issn":"07307268","usgsCitation":"Sciera, K., Isely, J.J., Tomasso, J., and Klaine, S., 2004, Influence of multiple water-quality characteristics on copper toxicity to fathead minnows (Pimephales promelas): Environmental Toxicology and Chemistry, v. 23, no. 12, p. 2900-2905, https://doi.org/10.1897/03-574.1.","startPage":"2900","endPage":"2905","numberOfPages":"6","costCenters":[],"links":[{"id":208613,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1897/03-574.1"},{"id":234465,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"23","issue":"12","noUsgsAuthors":false,"publicationDate":"2004-12-01","publicationStatus":"PW","scienceBaseUri":"505a3b54e4b0c8380cd6242f","contributors":{"authors":[{"text":"Sciera, K.L.","contributorId":74550,"corporation":false,"usgs":true,"family":"Sciera","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":408688,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Isely, J.

Temporal correlations directly affect both the estimate of rate and its standard error; the rate of deformation is a key product from geodetic measurements made in tectonically active areas. Various models of temporally correlated errors are developed and these provide relations between the power spectral density and the data covariance matrix. These relations are applied to two-color electronic distance meter (EDM) measurements made frequently in California over the past 15-20 years. Previous analysis indicated that these data have significant random walk error. Analysis using the noise models developed here indicates that the random walk model is valid for about 30% of the data. A second 30% of the data can be better modeled with power law noise with a spectral index between 1 and 2, while another 30% of the data can be modeled with a combination of band-pass-filtered plus random walk noise. The remaining 10% of the data can be best modeled as a combination of band-pass-filtered plus power law noise. This band-pass-filtered noise is a product of an annual cycle that leaks into adjacent frequency bands. For time spans of more than 1 year these more complex noise models indicate that the precision in rate estimates is better than that inferred by just the simpler, random walk model of noise.","language":"English","doi":"10.1029/2003JB002819","issn":"01480227","usgsCitation":"Langbein, J., 2004, Noise in two-color electronic distance meter measurements revisited: Journal of Geophysical Research B: Solid Earth, v. 109, no. 4, https://doi.org/10.1029/2003JB002819.","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":478100,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2003jb002819","text":"Publisher Index Page"},{"id":235453,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209205,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2003JB002819"}],"volume":"109","issue":"4","noUsgsAuthors":false,"publicationDate":"2004-04-14","publicationStatus":"PW","scienceBaseUri":"505a672ee4b0c8380cd731fb","contributors":{"authors":[{"text":"Langbein, J.","contributorId":16990,"corporation":false,"usgs":true,"family":"Langbein","given":"J.","affiliations":[],"preferred":false,"id":412802,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Next came the principal surface break, along 226 km of the Denali fault, with average right-lateral offsets of 4.5–5.1 m and a maximum offset of 8.8 m near its eastern end. The Denali fault trace is commonly left stepping and north side up. About 99 km of the fault ruptured through glacier ice, where the trace orientation was commonly influenced by local ice fabric. Finally, slip transferred southeastward onto the Totschunda fault and continued for another 66 km where dextral offsets average 1.6–1.8 m. The transition from the Denali fault to the Totschunda fault occurs over a complex 25-km-long transfer zone of right-slip and normal fault traces. Three methods of calculating average surface slip all yield a moment magnitude of </span><i>M</i><sub>w</sub><span> 7.8, in very good agreement with the seismologically determined magnitude of </span><strong>M</strong><span> 7.9. A comparison of strong-motion inversions for moment release with our slip distribution shows they have a similar pattern. The locations of the two largest pulses of moment release correlate with the locations of increasing steps in the average values of observed slip. This suggests that slip-distribution data can be used to infer moment release along other active fault traces.</span></p>","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120040626","usgsCitation":"Haeussler, P.J., Schwartz, D.P., Dawson, T.E., Stenner, H.D., Lienkaemper, J.J., Sherrod, B.L., Cinti, F.R., Montone, P., Craw, P., Crone, A.J., and Personius, S.F., 2004, Surface rupture and slip distribution of the Denali and Totschunda faults in the 3 November 2002 M 7.9 earthquake, Alaska: Bulletin of the Seismological Society of America, v. 94, no. 6B, p.

However, although DOM fluxes from throughfall and through litterfall can be large, little is known about the fate of DOM leached from plant canopies, or from the litter layer into the soil horizon. In this study, our objectives were to determine the importance of plant-litter leachate as a vehicle for DOM movement, and to track DOM decomposition [including dissolve organic carbon (DOC) and dissolved organic nitrogen (DON) fractions], as well as DOM chemical and isotopic dynamics, during a long-term laboratory incubation experiment using fresh leaves and litter from several ecosystem types. The water-extractable fraction of organic C was high for all five plant species, as was the biodegradable fraction; in most cases, more than 70% of the initial DOM was decomposed in the first 10 days of the experiment. The chemical composition of the DOM changed as decomposition proceeded, with humic (hydrophobic) fractions becoming relatively more abundant than nonhumic (hydrophilic) fractions over time. However, in spite of proportional changes in humic and nonhumic fractions over time, our data suggest that both fractions are readily decomposed in the absence of physicochemical reactions with soil surfaces. Our data also showed no changes in the <span>δ</span><sup>13</sup><span>C</span> signature of DOM during decomposition, suggesting that isotopic fractionation during DOM uptake is not a significant process.

To evaluate the relationship between the char composition and NOC sorption, a series of char samples were generated by pyrolyzing a wheat residue (Triticum aestivum L) for 6 h at temperatures between 300 ??C and 700 ??C and analyzed for their elemental compositions, surface areas, and surface functional groups. The samples were then studied for their abilities to sorb benzene and nitrobenzene from water. A commercial activated carbon was used as a reference carbonaceous sample. The char samples produced at high pyrolytic temperatures (500-700 ??C) were well carbonized and exhibited a relatively high surface area (>300 m2/g), little organic matter (<3%), and low oxygen content (???10%). By contrast, the chars formed at low temperatures (300-400 ??C) were only partially carbonized, showing significantly different properties (<200 m2/g surface area, 40-50% organic carbon, and >20% oxygen). The char samples exhibited a significant range of surface acidity/basicity because of their different surface polar-group contents, as characterized by the Boehm titration data and the NMR and FTIR spectra. The NOC sorption by high-temperature chars occurred almost exclusively by surface adsorption on carbonized surfaces, whereas the sorption by low-temperature chars resulted from the surface adsorption and the concurrent smaller partition into the residual organic-matter phase. The chars appeared to have a higher surface affinity for a polar solute (nitrobenzene) than for a nonpolar solute (benzene), the difference being related to the surface acidity/basicity of the char samples.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es035034w","issn":"0013936X","usgsCitation":"Chun, Y., Sheng, G., Chiou, G., and Xing, B., 2004, Compositions and sorptive properties of crop residue-derived chars: Environmental Science & Technology, v. 38, no. 17, p. 4649-4655, https://doi.org/10.1021/es035034w.","startPage":"4649","endPage":"4655","numberOfPages":"7","costCenters":[],"links":[{"id":234284,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":208506,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es035034w"}],"volume":"38","issue":"17","noUsgsAuthors":false,"publicationDate":"2004-07-23","publicationStatus":"PW","scienceBaseUri":"5059f93be4b0c8380cd4d4f5","contributors":{"authors":[{"text":"Chun, Y.","contributorId":15802,"corporation":false,"usgs":true,"family":"Chun","given":"Y.","email":"","affiliations":[],"preferred":false,"id":410550,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sheng, G.","contributorId":70961,"corporation":false,"usgs":true,"family":"Sheng","given":"G.","email":"","affiliations":[],"preferred":false,"id":410551,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chiou, G.T.","contributorId":7471,"corporation":false,"usgs":true,"family":"Chiou","given":"G.T.","email":"","affiliations":[],"preferred":false,"id":410549,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Xing, B.","contributorId":107896,"corporation":false,"usgs":true,"family":"Xing","given":"B.","email":"","affiliations":[],"preferred":false,"id":410552,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Subsurface drainage is practiced to insure trafficable field conditions for farm equipment and to reduce crop stress from excess water within the root zone. Although drainage is essential for economic crop production, there have been some significant environmental costs. Tile drainage systems tend to intercept nutrient (nitrate) rich soil-water and shunt it to surface water. Data from numerous monitoring studies have shown that a significant amount of the total nitrate load in Illinois is being delivered to surface water from tile drainage systems. In Illinois, these drainage systems are typically installed without control mechanisms and allow the soil to drain whenever the water table is above the elevation of the tile outlet. An assessment of water quality in the tile drained areas of Illinois showed that approximately 50 percent of the nitrate load was being delivered through the tile systems during the fallow period when there was no production need for drainage to occur. In 1998, a demonstration project to introduce drainage water management to producers in Illinois was initiated by NRCS4 An initial aspect of the project was to identify producers that were willing to manage their drainage system to create a raised water table during the fallow (November-March) period. Financial assistance from two federal programs was used to assist producers in retrofitting the existing drainage systems with control structures. Growers were also provided guidance on the management of the structures for both water quality and production benefits. Some of the retrofitted systems were monitored to determine the effect of the practice on water quality. This paper provides background on the water quality impacts of tile drainage in Illinois, the status of the demonstration project, preliminary monitoring results, and other observations.","largerWorkTitle":"Proceedings of the 8th International Drainage Symposium - Drainage VIII","conferenceTitle":"8th International Drainage Symposium - Drainage VIII","conferenceDate":"21 March 2004 through 24 March 2004","conferenceLocation":"Sacramento, CA","language":"English","isbn":"1892769360","usgsCitation":"Pitts, D., Cooke, R., and Terrio, P.J., 2004, Illinois drainage water management demonstration project, <i>in</i> Proceedings of the 8th International Drainage Symposium - Drainage VIII, Sacramento, CA, 21 March 2004 through 24 March 2004, p. 25-38.","startPage":"25","endPage":"38","numberOfPages":"14","costCenters":[],"links":[{"id":234189,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a386de4b0c8380cd6157c","contributors":{"editors":[{"text":"Cooke R.A.","contributorId":128333,"corporation":true,"usgs":false,"organization":"Cooke R.A.","id":536590,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Pitts, D.J.","contributorId":90511,"corporation":false,"usgs":true,"family":"Pitts","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":408896,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cooke, R.","contributorId":11561,"corporation":false,"usgs":true,"family":"Cooke","given":"R.","email":"","affiliations":[],"preferred":false,"id":408894,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Terrio, P.

The compression of elevation data poses a different set of problems and concerns than does the compression of images. Most notably, the usefulness of DEMs depends largely in the quality of their derivatives, such as slope and aspect. Three areas extracted from the U.S. Geological Survey's National Elevation Dataset were transformed to the wavelet domain using the third order filters of the Daubechies family (DAUB6), and were made sparse by setting 95 percent of the smallest wavelet coefficients to zero. The resulting raster is compressible to a corresponding degree. The effects of the nulled coefficients on the reconstructed DEM are noted as residuals in elevation, derived slope and aspect, and delineation of drainage basins and streamlines. A simple masking technique also is presented, that maintains the integrity and flatness of water bodies in the reconstructed DEM.","largerWorkTitle":"2004 IEEE International Geoscience and Remote Sensing Symposium proceedings","conferenceTitle":"2004 IEEE International Geoscience and Remote Sensing Symposium : Science for Society: Exploring and Managing a Changing Planet.

A low and depression velocity layer can seriously attenuate high frequency components of seismic data. Therefore, resolution and signal-to-noise (S/N) ratio of seismic data deteriorate. To enhance resolution and S/N ratio of seismic data, we designed a coupling compensatory inverse filter by using the single trace seismic data from Seismic Wave Detect System (SWDS) and common receivers on equal conditions. We designed an attenuating compensatory inverse filter by using seismic data from a microseismogram log. At last, in order to convert a shot gather from common receivers to a shot gather from SWDS, we applied the coupling compensatory inverse filter to the shot gather from common receivers. And then we applied the attenuating compensatory inverse filter to the coupling stacked seismic data to increase its resolution and S/N ratio. The results show that the resolution of seismic data from common receivers after processing by using the coupling compensatory inverse filter is nearly comparable with that of data from SWDS.

The long-term viability of lynx populations at the southern edge of their geographic range has been hypothesized to be dependent on old growth forests; however, lynx are a specialist predator on snowshoe hare Lepus americanus, a species associated with early-successional forests. To quantify the effects of succession and forest management on landscape-scale (100 km<sup>2</sup>) patterns of habitat occupancy by lynx, we compared landscape attributes in northern Maine, USA, where lynx had been detected on snow track surveys to landscape attributes where surveys had been conducted, but lynx tracks had not been detected. Models were constructed a <i>priori</i> and compared using logistic regression and Akaike's Information Criterion (AIC), which quantitatively balances data fit and parsimony. In the models with the lowest (i.e. best) AIC, lynx were more likely to occur in landscapes with much regenerating forest, and less likely to occur in landscapes with much recent clearcut, partial harvest and forested wetland. Lynx were not associated positively or negatively with mature coniferous forest. A probabilistic map of the model indicated a patchy distribution of lynx habitat in northern Maine. According to an additional survey of the study area for lynx tracks during the winter of 2003, the model correctly classified 63.5% of the lynx occurrences and absences. Lynx were more closely associated with young forests than mature forests; however, old-growth forests were functionally absent from the landscape. Lynx habitat could be reduced in northern Maine, given recent trends in forest management practices. Harvest strategies have shifted from clearcutting to partial harvesting. If this trend continues, future landscapes will shift away from extensive regenerating forests and toward landscapes dominated by pole-sized and larger stands. Because Maine presently supports the only verified populations of this federally threatened species in the eastern United States, changes in forest management practices could affect recovery efforts throughout that region.</p>","language":"English","publisher":"BioOne Complete","doi":"10.2981/wlb.2004.034","usgsCitation":"Hoving, C., Harrison, D., Krohn, W., Jakubas, W., and McCollough, M., 2004, Canada lynx Lynx canadensis habitat and forest succession in northern Maine, USA: Wildlife Biology, v. 10, no. 4, p. 285-294, https://doi.org/10.2981/wlb.2004.034.","productDescription":"10 p.","startPage":"285","endPage":"294","costCenters":[],"links":[{"id":234323,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Maine","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -70.48828125,\n              45.73685954736049\n            ],\n            [\n              -67.763671875,\n              45.79816953017265\n            ],\n            [\n              -67.763671875,\n              47.42808726171425\n            ],\n            [\n              -68.64257812499999,\n              47.368594345213374\n            ],\n            [\n              -69.345703125,\n              47.487513008956554\n            ],\n            [\n              -70.48828125,\n              45.73685954736049\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"10","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f33de4b0c8380cd4b6ac","contributors":{"authors":[{"text":"Hoving, C.L.","contributorId":32333,"corporation":false,"usgs":true,"family":"Hoving","given":"C.L.","email":"","affiliations":[],"preferred":false,"id":408782,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harrison, D.J.","contributorId":82022,"corporation":false,"usgs":true,"family":"Harrison","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":408784,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Krohn, W.B.","contributorId":64355,"corporation":false,"usgs":true,"family":"Krohn","given":"W.B.","email":"","affiliations":[],"preferred":false,"id":408783,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jakubas, W.J.","contributorId":15383,"corporation":false,"usgs":true,"family":"Jakubas","given":"W.J.","email":"","affiliations":[],"preferred":false,"id":408781,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"McCollough, M.A.","contributorId":84023,"corporation":false,"usgs":true,"family":"McCollough","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":408785,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

In working towards this goal, we describe our first prototype implemented over a local area network, where the image is distributed using LambdaRAM, on the memory of all nodes of a PC cluster driving a tiled display wall. Aggressive pre-fetching schemes employed by LambdaRAM help to reduce latency involved in remote memory access.

The information collected and used includes: a) detailed Quaternary geological mapping, b) over 650 geotechnical borings, c) probabilistic earthquake shaking information, and d) ground-water levels. Predictions of strain can be made using either empirical formulations or numerical simulations. In this project lateral spread displacements are estimated and new empirical relations to estimate future volumetric and shear strain are used. Geotechnical boring data to are used to: (a) develop isopach maps showing the thickness of sediment thatis likely to liquefy and deform under earthquake shaking; and (b) assess the variability in engineering properties within and between geologic map units. Preliminary results reveal that late Holocene deposits are likely to experience the greatest liquefaction-induced strains, while Holocene and late Pleistocene deposits are likely to experience significantly less horizontal and vertical strain in future earthquakes. Development of maps based on these analyses is feasible.","largerWorkTitle":"Geotechnical Special Publication","conferenceTitle":"Geotechnical Engineering for Transportation Projects: Proceedings of Geo-Trans 2004","conferenceDate":"27 July 2004 through 31 July 2004","conferenceLocation":"Los Angeles, CA","language":"English","issn":"08950563","usgsCitation":"Rosinski, A., Knudsen, K.L., Wu, J., Seed, R., and Real, C., 2004, Development of regional liquefaction-induced deformation hazard maps, <i>in</i> Geotechnical Special Publication, no. 126 I, Los Angeles, CA, 27 July 2004 through 31 July 2004, p. 797-806.","startPage":"797","endPage":"806","numberOfPages":"10","costCenters":[],"links":[{"id":234557,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"126 I","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0061e4b0c8380cd4f722","contributors":{"editors":[{"text":"Yegian M.K.Kavazanjian E.","contributorId":128426,"corporation":true,"usgs":false,"organization":"Yegian M.K.Kavazanjian E.","id":536581,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Rosinski, A.","contributorId":18150,"corporation":false,"usgs":true,"family":"Rosinski","given":"A.","email":"","affiliations":[],"preferred":false,"id":408248,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Knudsen, Kathy L.","contributorId":41188,"corporation":false,"usgs":false,"family":"Knudsen","given":"Kathy","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":408250,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wu, J.","contributorId":56998,"corporation":false,"usgs":true,"family":"Wu","given":"J.","email":"","affiliations":[],"preferred":false,"id":408252,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Seed, R.B.","contributorId":34691,"corporation":false,"usgs":true,"family":"Seed","given":"R.B.","email":"","affiliations":[],"preferred":false,"id":408249,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Real, C.R.","contributorId":45322,"corporation":false,"usgs":true,"family":"Real","given":"C.R.","email":"","affiliations":[],"preferred":false,"id":408251,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

A fauna of at least 107 invertebrate taxa consisting of two brachiopods, 95 mollusks (48 bivalves and 46 gastropods), at least eight arthropods, and at least two echinoids have been collected, ranging in age from late Miocene to late Pliocene. Rocks and fossils from the southwest part of the outcrop area, along the Estero de San Antonio, were deposited in a deep-water marine environment. At Meacham Hill, near the Stony Point Rock Quarry, and along the northern margin of the outcrop area at River Road and Wilson Grove, the Wilson Grove Formation was deposited in shallow marine to continental environments. At Meacham Hill, these shallow water deposits represent a brackish bay to continental environment, whereas at River Road and Wilson Grove, fossils suggest normal, euhaline (normal marine salinity) conditions. \r\n\r\nA few taxa from the River Road area suggest water temperatures slightly warmer than along the adjacent coast today because their modern ranges do not extend as far north in latitude as River Road. In addition, fossil collections from along River Road contain the bivalve mollusks Macoma addicotti (Nikas) and Nuttallia jamesii Roth and Naidu, both of which are restricted to the late Pliocene. The late Miocene Roblar tuff of Sarna-Wojcicki (1992) also crops out northeast of the River Road area and underlies the late Pliocene section at Wilson Grove by almost 300 m. Outcrops in the central part of the region are older than those to the northeast, and presumably younger than deposits to the southwest. The Roblar tuff of Sarna-Wojcicki (1992) occurs at Steinbeck Ranch in the central portion of the outcrop area. At Spring Hill, also in the central part of the outcrop area, the sanddollar Scutellaster sp., cf. S. oregonensis (Clark) has been recently collected. This species, questionably identified here, is restricted to the late Miocene from central California through Oregon. Outcrops at Salmon Creek, northeast of Steinbeck Ranch and also in the central part of the outcrop area, contain Aulacofusus? recurva (Gabb) and Turcica brevis Stewart, which are both restricted to the Pliocene, as well as Lirabuccinum portolaensis (Arnold) known from the early Pliocene of central and northern California and into the late Pliocene in southern California. These data suggest an overall pattern of older rocks and deeper water to the south and west, and younger rocks and shallower water to the east and north. Outcrops to the southwest, south of the Bloomfield fault, are not well dated but presumably are older than the late Miocene Roblar tuff of Sarna-Wojcicki (1992). Fossils in this part of the section are rare and are not useful in determining a precise age or environment of deposition for the lower part of the Wilson Grove Formation. However, sedimentary sequences and structures in the rocks here are useful and suggest probable outer shelf and slope water depths. Lituyapecten turneri (Arnold) which occurs in this part of the section has previously been restricted to the Pliocene, but its occurrence below the Roblar tuff of Sarna-Wojcicki (1992) indicates a revised late Miocene age for this taxon.\r\n\r\nThree possibly new gastropods (Mollusca) are reported here: Calyptraea (Trochita) n. sp. and Nucella sp., aff. N. lamellosa (Gmelin), both from the Bloomfield Quarry area, and Acanthinucella? n. sp. from the River Road area. These species are not described here because this venue is deemed insufficient for the description of new taxa.","language":"ENGLISH","doi":"10.3133/ofr20041017","usgsCitation":"Powell, C.L., Allen, J., and Holland, P.J., 2004, Invertebrate Paleontology of the Wilson Grove Formation (Late Miocene to Late Pliocene), Sonoma and Marin Counties, California, with some Observations on Its Stratigraphy, Thickness, and Structure: U.S. Geological Survey Open-File Report 2004-1017, 105 p.; 2 over-sized sheets, https://doi.org/10.3133/ofr20041017.","productDescription":"105 p.; 2 over-sized sheets","costCenters":[],"links":[{"id":180810,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":5216,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2004/1017/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48b7e4b07f02db534581","contributors":{"authors":[{"text":"Powell, Charles L.
