Our identification of paragenetically early types of pyrite, especially remnant colloform, crustiform, and layered growth textures of pyrite containing electrum and pyrrhotite, establishes unequivocally that gold mineralization was coeval with deposition of host rocks and not solely related to Paleozoic tectonic events. Ore horizons at the Haile deposit, South Carolina, contain many remnants of early pyrite: (1) fine-grained cubic pyrite disseminated along bedding; (2) fine- grained spongy, rounded masses of pyrite that may envelop or drape over pyrite cubes; (3) fragments of botryoidally and crustiform layered pyrite, and (4) pyritic infilling of vesicles and pumice. Detailed mineral chemistry by petrography, microprobe, SEM, and EDS analysis of replaced pumice and colloform structures containing both arsenic compositional banding and electrum points to coeval deposition of gold and the volcanic host rocks and, thus, confirms a syngenetic origin for the gold deposits. Early pyrite textures are present in other major deposits of the Carolina slate belt, such as Ridgeway and Barite Hill, and these provide strong evidence for models whereby the sulfide ores formed prior to tectonism. The role of Paleozoic metamorphism was to remobilize and concentrate gold and other minerals in structurally prepared sites. Recognizing the significance of paragenetically early pyrite and gold textures can play an important role in distinguishing sulfide ores that form in volcanic and sedimentary environments from those formed solely by metamorphic processes. Exploration strategies applied to the Carolina slate belt and correlative rocks in the eastern United States in the Avalonian basement will benefit from using syngenetic models for gold mineralization.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Economic Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2113/96.4.891","issn":"03610128","usgsCitation":"Foley, N., Ayuso, R., and Seal, R., 2001, Remnant colloform pyrite at the haile gold deposit, South Carolina: A textural key to genesis: Economic Geology, v. 96, no. 4, p. 891-902, https://doi.org/10.2113/96.4.891.","startPage":"891","endPage":"902","numberOfPages":"12","costCenters":[],"links":[{"id":207350,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2113/96.4.891"},{"id":232239,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"96","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aa6d7e4b0c8380cd850a4","contributors":{"authors":[{"text":"Foley, N.","contributorId":17800,"corporation":false,"usgs":true,"family":"Foley","given":"N.","email":"","affiliations":[],"preferred":false,"id":397010,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ayuso, R.

These include mathematical deconvolution of chemical analyses, direct microanalysis, sequential extraction procedures and density fractionation. A new methodology combining density fractionation with mathematical deconvolution of chemical analyses of whole coals and their density fractions has been evaluated. These coals formed part of the IEA-Coal Research project on the Modes of Occurrence of Trace Elements in Coal. Results were compared to a previously reported sequential extraction methodology and showed good agreement for most elements. For particular elements (Be, Mo, Cu, Se and REEs) in specific coals where disagreement was found, it was concluded that the occurrence of rare trace element bearing phases may account for the discrepancy, and modifications to the general procedure must be made to account for these.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Fuel","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier Science Ltd","publisherLocation":"Exeter, United Kingdom","doi":"10.1016/S0016-2361(00)00059-4","issn":"00162361","usgsCitation":"Querol, X., Klika, Z., Weiss, Z., Finkelman, R.B., Alastuey, A., Juan, R., Lopez-Soler, A., Plana, F., Kolker, A., and Chenery, S., 2001, Determination of element affinities by density fractionation of bulk coal samples: Fuel, v. 80, no. 1, p. 83-96, https://doi.org/10.1016/S0016-2361(00)00059-4.","startPage":"83","endPage":"96","numberOfPages":"14","costCenters":[],"links":[{"id":207084,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0016-2361(00)00059-4"},{"id":231687,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"80","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ffa3e4b0c8380cd4f2d4","contributors":{"authors":[{"text":"Querol, X.","contributorId":12340,"corporation":false,"usgs":true,"family":"Querol","given":"X.","email":"","affiliations":[],"preferred":false,"id":400492,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Klika, Z.","contributorId":69431,"corporation":false,"usgs":true,"family":"Klika","given":"Z.","email":"","affiliations":[],"preferred":false,"id":400497,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Weiss, Z.","contributorId":94562,"corporation":false,"usgs":true,"family":"Weiss","given":"Z.","email":"","affiliations":[],"preferred":false,"id":400499,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Finkelman, R.

Model creep is driven by screw dislocations at 12 km depth under the Hayward and other regional faults. Inferred depth to locking varies along strike from 4-12 km. (12 km implies no locking.) Our models require locked patches under the central Hayward fault, consistent with a M6.8 earthquake in 1868, but the geometry and extent of locking under the north and south ends depend critically on assumptions regarding continuity and creep behavior of the fault at its ends. For the northern onshore part of the fault, our models contain 1.4-1.7 times more stored moment than the model of Bu??rgmann et al. [2000]; 45-57% of this stored moment resides in creeping areas. It is important for seismic hazard estimation to know how much of this moment is released coseismically or as aseismic afterslip.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geophysical Research Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1029/2001GL012979","issn":"00948276","usgsCitation":"Simpson, R., Lienkaemper, J.J., and Galehouse, J., 2001, Variations in creep rate along the Hayward Fault, California, interpreted as changes in depth of creep: Geophysical Research Letters, v. 28, no. 11, p. 2269-2272, https://doi.org/10.1029/2001GL012979.","startPage":"2269","endPage":"2272","numberOfPages":"4","costCenters":[],"links":[{"id":478968,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2001gl012979","text":"Publisher Index Page"},{"id":207349,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2001GL012979"},{"id":232238,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc17be4b08c986b32a5c4","contributors":{"authors":[{"text":"Simpson, R.W.","contributorId":76738,"corporation":false,"usgs":true,"family":"Simpson","given":"R.W.","email":"","affiliations":[],"preferred":false,"id":397008,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lienkaemper, J.

Results show that for 1980-1996 the mean annual total N flux to the Gulf of Mexico was 1 568 000 t yr-1. The flux was about 61% nitrate N, 37% organic N, and 2% ammonium N. The flux of nitrate N to the Gulf has approximately tripled in the last 30 years with most of the increase occurring between 1970 and 1983. The mean annual N flux has changed little since the early 1980s, but large year-to-year variations in N flux occur because of variations in precipitation. During wet years the N flux can increase by 50% or more due to flushing of nitrate N that has accumulated in the soils and unsaturated zones in the basin. The principal source areas of N are basins in southern Minnesota, Iowa, Illinois, Indiana, and Ohio that drain agricultural land. Basins in this region yield 1500 to more than 3100 kg N km-2 yr-1 to streams, several times the N yield of basins outside this region.","language":"English","publisher":"Wiley","doi":"10.2134/jeq2001.302329x","issn":"00472425","usgsCitation":"Goolsby, D.A., Battaglin, W., Aulenbach, B., and Hooper, R.P., 2001, Nitrogen input to the Gulf of Mexico, v. 30, no. 2, p. 329-336, https://doi.org/10.2134/jeq2001.302329x.","productDescription":"8 p.","startPage":"329","endPage":"336","numberOfPages":"8","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":232718,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Mississippi–Atchafalaya River basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -92.28515625,\n              46.255846818480315\n            ],\n            [\n              -93.955078125,\n              46.98025235521883\n            ],\n            [\n              -98.173828125,\n              48.3416461723746\n            ],\n            [\n              -101.6015625,\n              48.22467264956519\n            ],\n            [\n              -102.12890625,\n              46.01222384063236\n            ],\n            [\n              -100.107421875,\n              42.94033923363181\n            ],\n            [\n              -97.03125,\n              41.44272637767212\n            ],\n            [\n              -94.306640625,\n              38.61687046392973\n            ],\n            [\n              -93.515625,\n              34.45221847282654\n            ],\n            [\n              -94.39453125,\n              30.221101852485987\n            ],\n            [\n              -92.46093749999999,\n              28.844673680771795\n            ],\n            [\n              -89.6484375,\n              28.844673680771795\n            ],\n            [\n              -88.330078125,\n              30.14512718337613\n            ],\n            [\n              -88.505859375,\n              34.23451236236987\n            ],\n            [\n              -87.451171875,\n              39.57182223734374\n            ],\n            [\n              -85.341796875,\n              39.30029918615029\n            ],\n            [\n              -78.75,\n              39.57182223734374\n            ],\n            [\n              -75.234375,\n              42.09822241118974\n            ],\n            [\n              -75.41015624999999,\n              44.59046718130883\n            ],\n            [\n              -79.1015625,\n              42.94033923363181\n            ],\n            [\n              -82.6171875,\n              41.44272637767212\n            ],\n            [\n              -87.5390625,\n              41.77131167976407\n            ],\n            [\n              -89.296875,\n              43.644025847699496\n            ],\n            [\n              -91.318359375,\n              45.9511496866914\n            ],\n            [\n              -92.28515625,\n              46.255846818480315\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"30","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a66e2e4b0c8380cd73051","contributors":{"authors":[{"text":"Goolsby, D.

Assessment of the occurrence of nature reserves across ranges of elevation and soil productivity classes indicates that nature reserves are most frequently found at higher elevations and on less productive soils. The distribution of plants and animals suggests that the greatest number of species is found at lower elevations. A preliminary assessment of the occurrence of mapped land cover types indicates that ???60% of mapped cover types have <10% of their area in nature reserves Land ownership patterns show that areas of lower elevation and more productive soils are most often privately owned and already extensively converted to urban and agricultural uses. Thus any effort to establish a system of nature reserves that captures the full geographical and ecological range of cover types and species must fully engage the private sector.","language":"English","publisher":"Wiley","doi":"10.1890/1051-0761(2001)011[0999:NRDTCT]2.0.CO;2","issn":"10510761","usgsCitation":"Scott, J.M., Davis, F., McGhie, R., Wright, R., Groves, C., and Estes, J., 2001, Nature reserves: Do they capture the full range of America's biological diversity?: Ecological Applications, v. 11, no. 4, p. 999-1007, https://doi.org/10.1890/1051-0761(2001)011[0999:NRDTCT]2.0.CO;2.","productDescription":"9 p.","startPage":"999","endPage":"1007","costCenters":[],"links":[{"id":232676,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"11","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a639de4b0c8380cd725d6","contributors":{"authors":[{"text":"Scott, J.

Conservation of bird habitats is a major focus of effort by Partners in Flight, an international coalition of agencies, citizens, and other groups dedicated to 'keeping common birds common'.  USGS worked on a planning team to publish a bird conservation plan for the Upper Great Lakes Plain ecoregion (PIF 16), which includes large portions of southern Wisconsin, southern Michigan and parts of Minnesota, Iowa, Illinois, Indiana, and Ohio.  The conservation plan outlines specific habitat restoration and bird population objectives for the ecoregion over the next decade. The plan provides a context for on-the-ground conservation implementation by the US Fish and Wildlife Service, the USDA Natural Resources Conservation Service, the US Forest Service, states, and conservation groups.

Download from website:  http://www.blm.gov/wildlife/pifplans.htm. \rThe Upper Great Lakes Plain covers the southern half of Michigan, northwest Ohio, northern Indiana, northern Illinois, southern Wisconsin, and small portions of southwest Minnesota and northwest Iowa. Glacial moraines and dissected plateaus are characteristic of the topography. Broadleaf forests, oak savannahs, and a variety of prairie communities are the natural vegetation types. A oDriftless Areao was not glaciated during the late Pleistocene and emerged as a unique area of great biological diversity.  Priority bird species for the area include the Henslow's Sparrow, Sedge Wren, Bobolink, Golden-winged Warbler, Cerulean Warbler, Black-billed Cuckoo, and Red-headed Woodpecker.  There are many large urban centers in this area whose growth and sprawl will continue to consume land. The vast majority of the presettlement forest and oak savannah grasslands already have been converted to agriculture. The conversion to cropland may have benefitted some grassland birds, and forest birds still persist. Rates of cowbird parasitism and nest predation in this heavily fragmented region, however, are extremely high and it is possible that only those bird communities in the few remaining expanses of contiguous habitat are self-sustaining. Forest habitat needs to be retained or restored so that a significant number of patches of sufficient size and quality each support a healthy population of Cerulean Warblers. It is assumed that each of these patches will then support the full range of forest birds. The total area of savannah habitat also should be increased, although the need for large blocks is not as apparent. Those few areas of grassland that still exist should be retained.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"La Crosse, WI","usgsCitation":"Knutson, M.G., Butcher, G., Fitzgerald, J., and Shieldcastle, J., 2001, Partners in flight bird conservation plan for the Upper Great Lakes Plain (Physiographic Area 16).","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":201374,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":11983,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://www.blm.gov/wildlife/pifplans.htm","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b23e4b07f02db6ae368","contributors":{"authors":[{"text":"Knutson, M.

Existence of the new phase is critical for understanding the phase relations among the hydrates at low to moderate pressures, and may also have important implications for understanding the hydrogen bonding in H2O and the behavior of water in the planetary bodies, such as Europa, of the outer solar system.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Physical Chemistry A","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/jp002735w","issn":"10895639","usgsCitation":"Chou, I., Sharma, A., Burruss, R., Hemley, R., Goncharov, A., Stern, L., and Kirby, S.H., 2001, Diamond-anvil cell observations of a new methane hydrate phase in the 100-MPa pressure range: Journal of Physical Chemistry A, v. 105, no. 19, p. 4664-4668, https://doi.org/10.1021/jp002735w.","startPage":"4664","endPage":"4668","numberOfPages":"5","costCenters":[],"links":[{"id":207638,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/jp002735w"},{"id":232760,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"105","issue":"19","noUsgsAuthors":false,"publicationDate":"2001-04-20","publicationStatus":"PW","scienceBaseUri":"505a00a7e4b0c8380cd4f83b","contributors":{"authors":[{"text":"Chou, I.-M. 0000-0001-5233-6479","orcid":"https://orcid.org/0000-0001-5233-6479","contributorId":44283,"corporation":false,"usgs":true,"family":"Chou","given":"I.-M.","affiliations":[{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":false,"id":397115,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sharma, A.","contributorId":59978,"corporation":false,"usgs":true,"family":"Sharma","given":"A.","email":"","affiliations":[],"preferred":false,"id":397117,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Burruss, R.C. 0000-0001-6827-804X","orcid":"https://orcid.org/0000-0001-6827-804X","contributorId":99574,"corporation":false,"usgs":true,"family":"Burruss","given":"R.C.","affiliations":[],"preferred":false,"id":397119,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hemley, R.J.","contributorId":70118,"corporation":false,"usgs":true,"family":"Hemley","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":397118,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Goncharov, A.F.","contributorId":12230,"corporation":false,"usgs":true,"family":"Goncharov","given":"A.F.","email":"","affiliations":[],"preferred":false,"id":397113,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Stern, L.A.","contributorId":38293,"corporation":false,"usgs":true,"family":"Stern","given":"L.A.","email":"","affiliations":[],"preferred":false,"id":397114,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Kirby, S.

To remedy this situation and to provide baseline data for other isotope hydrology studies, more than 4800, depth- and width-integrated, stream samples from 391 selected sites within the USGS National Stream Quality Accounting Network (NASQAN) and Hydrologic Benchmark Network (HBN) were analysed for &delta;<sup>18</sup>O and &delta;<sup>2</sup>H (<a title=\"Link to external resource: http://water.usgs.gov/pubs/ofr/ofr00-160/pdf/ofr00-160.pdf\" href=\"http://water.usgs.gov/pubs/ofr/ofr00-160/pdf/ofr00-160.pdf\">http://water.usgs.gov/pubs/ofr/ofr00-160/pdf/ofr00-160.pdf</a>). Each site was sampled bimonthly or quarterly for 2&middot;5 to 3 years between 1984 and 1987. The ability of this dataset to serve as a proxy for the isotopic composition of modern precipitation in the USA is supported by the excellent agreement between the river dataset and the isotopic compositions of adjacent precipitation monitoring sites, the strong spatial coherence of the distributions of &delta;<sup>18</sup>O and &delta;<sup>2</sup>H, the good correlations of the isotopic compositions with climatic parameters, and the good agreement between the &lsquo;national&rsquo; meteoric water line (MWL) generated from unweighted analyses of samples from the 48 contiguous states of &delta;<sup>2</sup>H=8&middot;11&delta;<sup>18</sup>O+8&middot;99 (<i>r</i><sup>2</sup>=0&middot;98) and the unweighted global MWL of sites from the Global Network for Isotopes in Precipitation (GNIP) of the International Atomic Energy Agency and the World Meteorological Organization (WMO) of &delta;<sup>2</sup>H=8&middot;17&delta;<sup>18</sup>O+10&middot;35.</p>\n</div>\n<div class=\"para\">\n<p>The national MWL is composed of water samples that arise in diverse local conditions where the local meteoric water lines (LMWLs) usually have much lower slopes. Adjacent sites often have similar LMWLs, allowing the datasets to be combined into regional MWLs. The slopes of regional MWLs probably reflect the humidity of the local air mass, which imparts a distinctive evaporative isotopic signature to rainfall and hence to stream samples. Deuterium excess values range from 6 to 15&permil; in the eastern half of the USA, along the northwest coast and on the Colorado Plateau. In the rest of the USA, these values range from &minus;2 to 6&permil;, with strong spatial correlations with regional aridity. The river samples have successfully integrated the spatial variability in the meteorological cycle and provide the best available dataset on the spatial distributions of &delta;<sup>18</sup>O and &delta;<sup>2</sup>H values of meteoric waters in the USA.</p>\n</div>","language":"English","publisher":"Wiley","doi":"10.1002/hyp.217","issn":"08856087","usgsCitation":"Kendall, C., and Coplen,

The details of the spatial distribution are especially critical in complex terrain because the watersheds are generally small in size, and small position errors in the forecast or observed placement of the precipitation can distribute the rain over the wrong watershed. In addition to the need for good precipitation estimates and predictions, accurate flood prediction requires a surface-hydrologic model that is capable of predicting stream or river discharge based on the precipitation-rate input data. Different techniques for the estimation and prediction of convective precipitation will be applied to the Buffalo Creek, Colorado flash flood of July 1996, where over 75 mm of rain from a thunderstorm fell on the watershed in less than 1 h. The hydrologic impact of the precipitation was exacerbated by the fact that a significant fraction of the watershed experienced a wildfire approximately two months prior to the rain event. Precipitation estimates from the National Weather Service's operational Weather Surveillance Radar-Doppler 1988 and the National Center for Atmospheric Research S-band, research, dual-polarization radar, colocated to the east of Denver, are compared. In addition, very short range forecasts from a convection-resolving dynamic model, which is initialized variationally using the radar reflectivity and Doppler winds, are compared with forecasts from an automated-algorithmic forecast system that also employs the radar data. The radar estimates of rain rate, and the two forecasting systems that employ the radar data, have degraded accuracy by virtue of the fact that they are applied in complex terrain. Nevertheless, the radar data and forecasts from the dynamic model and the automated algorithm could be operationally useful for input to surface-hydrologic models employed for flood warning. Precipitation data provided by these various techniques at short time scales and at fine spatial resolutions are employed as detailed input to a distributed-parameter hydrologic model for flash-flood prediction and analysis. With the radar-based precipitation estimates employed as input, the simulated flood discharge was similar to that observed. The dynamic-model precipitation forecast showed the most promise in providing a significant discharge-forecast lead time. The algorithmic system's precipitation forecast did not demonstrate as much skill, but the associated discharge forecast would still have been sufficient to have provided an alert of impending flood danger.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrologic Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1061/(ASCE)1084-0699(2001)6:4(265)","issn":"10840699","usgsCitation":"Yates, D., Warner, T., Brandes, E., Leavesley, G., Sun, J., and Mueller, C., 2001, Evaluation of flash-flood discharge forecasts in complex terrain using precipitation: Journal of Hydrologic Engineering, v. 6, no. 4, p. 265-274, https://doi.org/10.1061/(ASCE)1084-0699(2001)6:4(265).","startPage":"265","endPage":"274","numberOfPages":"10","costCenters":[],"links":[{"id":232397,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207444,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/(ASCE)1084-0699(2001)6:4(265)"}],"volume":"6","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0c75e4b0c8380cd52b62","contributors":{"authors":[{"text":"Yates, D.","contributorId":42391,"corporation":false,"usgs":true,"family":"Yates","given":"D.","email":"","affiliations":[],"preferred":false,"id":397181,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Warner, T.T.","contributorId":7459,"corporation":false,"usgs":true,"family":"Warner","given":"T.T.","email":"","affiliations":[],"preferred":false,"id":397178,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brandes, E.A.","contributorId":22534,"corporation":false,"usgs":true,"family":"Brandes","given":"E.A.","email":"","affiliations":[],"preferred":false,"id":397179,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Leavesley, G.H.","contributorId":93895,"corporation":false,"usgs":true,"family":"Leavesley","given":"G.H.","email":"","affiliations":[],"preferred":false,"id":397183,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Sun, Jielun","contributorId":33443,"corporation":false,"usgs":true,"family":"Sun","given":"Jielun","email":"","affiliations":[],"preferred":false,"id":397180,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mueller, C.K.","contributorId":47944,"corporation":false,"usgs":true,"family":"Mueller","given":"C.K.","email":"","affiliations":[],"preferred":false,"id":397182,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

These faults, which are part of the Fluorspar Area fault complex in southeastern Illinois, are directly in line with the northeast-trending seismic zone. The reflection data were acquired using an elastic weight-drop source recorded to 500 msec by a 48-geophone array (24-fold) with a 10-ft (??3.0m) station interval. Recognizable reflections were recorded to about 200 msec (100-150 m). The effects of multiple reflections, numerous diffractions, low apparent velocity (i.e., steeply dipping) noise, and the relatively low-frequency content of the recorded signal provided challenges for data processing and interpreting subtle fault offsets. Data processing steps that were critical to the detection of faults included residual statics, post-stack migration, deconvolution, and noise-reduction filtering. Seismic migration was crucial for detecting and mitigating complex fault-related diffraction patterns, which produced an apparent 'folding' of reflectors on unmigrated sections. Detected individual offsets of shallow reflectors range from 5 to 10 m for the top of Paleozoic bedrock and younger strata. The migrated sections generally indicate vertical to steeply dipping normal and reverse faults, which in places outline small horsts and/or grabens. Tilting or folding of stratal reflectors associated with faulting is also locally observed. At one site, the observed faulting is superimposed over a prominent antiformal structure, which may itself be a product of the Quaternary deformation that produced the steep normal and reverse faults. Our results suggest that faulting of the Paleozoic bedrock and younger sediments of the northern Mississippi embayment is more pervasive and less localized than previously thought.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120000039","issn":"00371106","usgsCitation":"McBride, J., and Nelson, W., 2001, Seismic reflection images of shallow faulting, northernmost Mississippi embayment, north of the New Madrid seismic zone: Bulletin of the Seismological Society of America, v. 91, no. 1, p. 128-129, https://doi.org/10.1785/0120000039.","startPage":"128","endPage":"129","numberOfPages":"2","costCenters":[],"links":[{"id":207455,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120000039"},{"id":232418,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"91","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8b42e4b08c986b3176e3","contributors":{"authors":[{"text":"McBride, J.H.","contributorId":99712,"corporation":false,"usgs":true,"family":"McBride","given":"J.H.","email":"","affiliations":[],"preferred":false,"id":398347,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nelson, W.J.","contributorId":17762,"corporation":false,"usgs":true,"family":"Nelson","given":"W.J.","email":"","affiliations":[],"preferred":false,"id":398346,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Recent genetic studies have shown these fish to have important genetic diversity and a unique evolutionary history when compared to coastal rainbow trout. Increased levels of allelic diversity have been found in this species at the southern extent of its range. In this study we describe the trout in the Sierra Madre Occidental from the rios Yaqui, Mayo, Casas Grandes and de Bavispe, and their relationship to the more southern distribution of Mexican golden trout (O. chrysogaster) using 11 microsatellite loci. Microsatellite allelic diversity in Mexican trout was high with a mean of 6.6 alleles/locus, average heterozygosity = 0.35, and a mean Fst = 0.43 for all loci combined. Microsatellite data were congruent with previously published mtDNA results showing unique panmictic population structure in the Rio Yaqui trout that differs from Pacific coastal trout and Mexican golden trout. These data also add support for the theory of headwaters transfer of trout across the Continental Divide from tributaries of the Rio de Bavispe into the Rio Casas Grandes. Rio Mayo trout share a close genetic relationship to trout in Rio Yaqui, but sample sizes from the Rio Mayo prevent significant comparisons in this study. Microsatellite analyses show significant allelic frequency differences between Rio Yaqui trout and O. chrysogaster in Sinaloa and Durango Mexico, adding further support for a unique evolutionary status for this group of northwestern Mexican trout.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Genetica","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1013777701213","issn":"00166707","usgsCitation":"Nielsen, J., and Sage, G.K., 2001, Microsatellite analyses of the trout of northwest Mexico: Genetica, v. 111, no. 1-3, p. 269-278, https://doi.org/10.1023/A:1013777701213.","startPage":"269","endPage":"278","numberOfPages":"10","costCenters":[],"links":[{"id":233489,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":208077,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1013777701213"}],"volume":"111","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a56a0e4b0c8380cd6d6f0","contributors":{"authors":[{"text":"Nielsen, J.L.","contributorId":105665,"corporation":false,"usgs":true,"family":"Nielsen","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":394686,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sage, G.

Total Hg (dissolved plus colloidal suspended sediment) concentrations ranged from the detection limit at the site below Shasta Dam in September 1996 to 81 ng/L at the Colusa site in January 1997, demonstrating that colloidal sediment plays an important role in the downriver Hg transport. Sequential extractions of colloid concentrates indicate that the greatest amount of Hg associated with sediment was found in the “residual” (mineral) phase with a significant quantity also occurring in the “oxidizable” phase. Only a minor amount of Hg was observed in the “reducible” phase.

Coastal complexity (plan-view tortuosity of the coastline) is a potentially useful parameter, since it interacts strongly with both marine and terrestrial forcing functions to determine coastal energy regimes and water residence times, and since 'open' vs. 'sheltered' categories are important components of most coastal habitat classification schemes. This study employs the World Vector Shoreline (WVS) dataset, originally developed at a scale of 1:250 000. Coastline complexity measures are generated using a modification of the Angle Measurement Technique (AMT), in which the basic measurement is the angle between two lines of specified length drawn from a selected point to the closest points of intersection with the coastline. Repetition of these measurements for different lengths at the same point yields a distribution of angles descriptive of the extent and scale of complexity in the vicinity of that point; repetition of the process at different points on the coast provides a basis for comparing both the extent and the characteristic scale of coastline variation along different reaches of the coast. The coast of northwestern Mexico (Baja California and the Gulf of California) was used as a case study for initial development and testing of the method. The characteristic angle distribution plots generated by the AMT analysis were clustered using LOICZVIEW, a high dimensionality clustering routine developed for large-scale coastal classification studies. The results show distinctive differences in coastal environments that have the potential for interpretation in terms of both biotic and hydrogeochemical environments, and that can be related to the resolution limits and uncertainties of the shoreline data used. These objective, quantitative measures of coastal complexity as a function of scale can be further developed and combined with other data sets to provide a key component of functional classification of coastal environments. ?? 2001 Elsevier Science B.V.

Leaf expansion, the live/total ratio of plant aboveground biomass, and the aboveground regrowth rate after the initial harvests were significantly reduced with increasing Cd concentration in the growth medium. Of the four physiological responses measured, only photosynthesis and AEC responded to the Cd treatment before damage was visually apparent. Also, these indices were significantly correlated with leaf expansion rate and live/total ratio in most instances. Except at the end of the experiment, when the most stressed plants began to die, the Fv/Fm ratio was not significantly affected by the Cd treatment. The leaf spectral reflectance parameters showed no significant change during the entire treatment period. The significant correlation between the stress indicators and plant growth supported the findings that photosynthesis and AEC were the most responsive of the indicators tested, however, further research investigating other chlorophyll fluorescence and leaf reflectance parameters may demonstrate as well the value of these indicators in quantifying sublethal stress. ?? 2001 Elsevier Science B.V.

One of these sites, Lake Apopka, is also a eutrophic system that has been the focus of several case studies reporting altered reproductive activity linked to bioaccumulation of persistent organochlorine chemicals in aquatic species. The present study was initiated to determine if brown bullheads (Ameriurus nebulosus) from the north marsh of Lake Apopka (Lake Apopka Marsh) exhibit an altered capacity to detoxify environmental chemicals through hepatic glutathione S-transferase (GST)-mediated conjugation as compared with bullheads from a nearby reference site (Lake Woodruff). We also compared plasma sex hormone concentrations (testosterone, 17-?? estradiol, and 11 keto-testosterone) in bullheads from the two sites. Female bullheads from Lake Apopka had 40% lower initial rate GST conjugative activity toward 1-chloro-2,4-dinitrobenzene (CDNB), 50% lower activity towards p-nitrobutyl chloride (NBC), 33% lower activity toward ethacrynic acid (ECA), and 43% lower activity toward ??5-androstene-3,17-dione (??5-ADI), as compared with female bullheads from Lake Woodruff. Enzyme kinetic analyses demonstrated that female bullheads from Lake Apopka had lower GST-catalyzed CDNB clearance than did female Lake Woodruff bullheads. Western blotting studies of bullhead liver cytosolic proteins demonstrated that the reduced GST catalytic activities in female Lake Apopka bullheads were accompanied by lower expression of hepatic GST protein. No site differences were observed with respect to GST activities or GST protein expression in male bullheads. Female Lake Apopka bullheads also had elevated concentrations of plasma androgens (testosterone and 11-ketotestosterone) as compared with females from Lake Woodruff. In contrast, male Lake Apopka bullheads had elevated levels of plasma estrogen but similar levels of androgens as compared with male bullheads from Lake Woodruff. Collectively, our studies indicate the presence of reduced GST protein expression, reduced GST conjugative capacity and altered sex steroid homeostasis in female bullheads from a contaminated field site in Central Florida. The implications of these physiological alterations in terms of pollutant biotransformation and reproduction are discussed. ?? 2001 Elsevier Science B.V.

Each camera is characterized by small physical size and mass (∼6×6×12 cm, including baffle; &lt;500 g), low power requirements (&lt;2.5 W, including power supply losses), and high science performance (1000×1000 pixel, low noise). The Wide Angle (WA) camera will have the capability to map Mars in five visible and two ultraviolet spectral bands at a resolution of better than 8 km/pixel under the worst case downlink data rate. Under better downlink conditions the WA will provide kilometer-scale global maps of atmospheric phenomena such as clouds, hazes, dust storms, and the polar hood. Limb observations will provide additional detail on atmospheric structure at 1/3 scale-height resolution. The Medium Angle (MA) camera is designed to study selected areas of Mars at regional scale. From 400 km altitude its 6° FOV, which covers ∼40 km at 40 m/pixel, will permit all locations on the planet except the poles to be accessible for image acquisitions every two mapping cycles (roughly 52 sols). Eight spectral channels between 425 and 1000 nm provide the ability to discriminate both atmospheric and surface features on the basis of composition. The primary science objectives of MARCI are to (1) observe Martian atmospheric processes at synoptic scales and mesoscales, (2) study details of the interaction of the atmosphere with the surface at a variety of scales in both space and time, and (3) examine surface features characteristic of the evolution of the Martian climate over time. MARCI will directly address two of the three high-level goals of the Mars Surveyor Program: Climate and Resources. Life, the third goal, will be addressed indirectly through the environmental factors associated with the other two goals.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/1999JE001145","issn":"01480227","usgsCitation":"Malin, M.C., Bell, J., Calvin, W., Clancy, R., Haberle, R., James, P., Lee, S., Thomas, P., and Caplinger, M., 2001, Mars Color Imager (MARCI) on the Mars Climate Orbiter: Journal of Geophysical Research E: Planets, v. 106, no.
