This depth - age relation is based on a join between the Vostok deuterium profile (D) and the stable oxygen isotope ratio (18O) record of paleotemperature from a calcitic core at Devils Hole, Nevada, using the algorithm developed by Landwehr and Winograd (2001). Both the control points defining the V-DH chronology and the numeric values for the chronology are given. In addition, a plausible chronology for a deformed bottom portion of the Vostok core developed with this algorithm is presented. Landwehr and Winograd (2001) demonstrated the broader utility of their algorithm by applying it to another appropriate Antarctic paleotemperature record, the Antarctic Dome Fuji ice core 18O record. Control points for this chronology are also presented in this report but deemed preliminary because, to date, investigators have published only the visual trace and not the numeric values for the Dome Fuji 18O record. The total uncertainty that can be associated with the assigned ages is also given.\r\n\r\n","language":"ENGLISH","doi":"10.3133/ofr2002266","usgsCitation":"Landwehr, J., 2002, Ice Core Depth-Age Relation for Vostok delta-D and Dome Fuji delta-18O Records Based on the Devils Hole Paleotemperature Chronology: U.S. Geological Survey Open-File Report 2002-266, 53 p.

This publication consists of three parts:</p>\n<br/>\n<p>1. Documentation in the form of a this publication's Open File text, or readme, describing the digital data, how to obtain it, as well as the original map explanation pamphlet. The documentation also consists of FGDC metadata, and a file describing any revisions to the data in this report. All of the documentaion components are available in a variety of file formats.<br/>\n2. Three Arc/Info (ESRI) formatted coverages of the geologic database, distributed in Arc Interchange (e00) format. The spatial databases in this component of the report consist vector-based GIS datasets that represent geologic contacts, faults, map units, and volcanic vents in the study area, as well as localities of K/Ar samples discussed in the original report, and geologic structure measurements.<br/>\n3. Plottable map representations of the database at 1:24,000 scale in PostScript and Adobe PDF formats. The plottable files consist of a color geologic map derived from the spatial database, composited with a topographic base map in the form of the USGS Digital Raster Graphic for the map area. Color symbology from each of these datasets is maintained, which can cause plot file sizes to be large.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr02273","usgsCitation":"Wilshire, H.G., Bedford, D., and Coleman, T., 2002, Digital version of \"Open-File Report 92-183: Geologic map of the Granite Spring Quadrangle, San Bernardino County, California\": U.S. Geological Survey Open-File Report 2002-273, Report: 27 p.; 1 Plate: 22.0 x 32.0 inches; 3 Metadata Files; 4 Data Files, https://doi.org/10.3133/ofr02273.","productDescription":"Report: 27 p.; 1 Plate: 22.0 x 32.0 inches; 3 Metadata Files; 4 Data Files","numberOfPages":"27","additionalOnlineFiles":"Y","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":172486,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr02273.jpg"},{"id":110331,"rank":7,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_52000.htm","linkFileType":{"id":5,"text":"html"},"description":"52000"},{"id":3627,"rank":6,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/0273/","linkFileType":{"id":5,"text":"html"}},{"id":283811,"rank":2,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2002/0273/of02-273data.tar"},{"id":283810,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2002/0273/pdf/of02-273_3a.pdf","text":"Plate 1","linkFileType":{"id":1,"text":"pdf"}},{"id":283808,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2002/0273/pdf/of02-273_1a.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":283809,"rank":4,"type":{"id":16,"text":"Metadata"},"url":"https://pubs.usgs.gov/of/2002/0273/of02-273_1b.html"}],"scale":"24000","projection":"Universal Transverse Mercator","datum":"1927 North American Datum","country":"United States","state":"California","county":"San Bernardino County","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -115.875,35.25 ], [ -115.875,35.375 ], [ -115.75,35.375 ], [ -115.75,35.25 ], [ -115.875,35.25 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae2e4b07f02db688bc3","contributors":{"authors":[{"text":"Wilshire, Howard G.","contributorId":68346,"corporation":false,"usgs":true,"family":"Wilshire","given":"Howard","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":222614,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bedford, David R.","contributorId":26352,"corporation":false,"usgs":true,"family":"Bedford","given":"David R.","affiliations":[],"preferred":false,"id":222612,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Coleman, Teresa","contributorId":42282,"corporation":false,"usgs":true,"family":"Coleman","given":"Teresa","email":"","affiliations":[],"preferred":false,"id":222613,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Mineral deposit models are the keystone in combining the diverse geoscience information on geology, mineral occurrences, geophysics, and geochemistry used in resource assessments and mineral exploration. Far too few thoroughly explored mineral deposits are available in most local areas for reliable identification of the important geoscience variables or for robust estimation of undiscovered deposits—thus we need mineral-deposit models. Globally based deposit models, such as those presented here, allow recognition of important features because the global models demonstrate how common different features are. Well-designed and -constructed deposit models allow geologists to know from observed geologic environments the possible mineral deposit types that might exist, and allow economists to determine the possible economic viability of these resources in the region. Thus, mineral deposit models play the central role in transforming geoscience information to a form useful to policy makers. The foundation of mineral deposit models is information about known deposits—the purpose of this publication is to make this kind of information available in digital form for a group of porphyry copper deposits.\n\nThis publication contains a computer file of information on porphyry copper deposits around the world. It also presents new grade and tonnage models for three subtypes of porphyry copper deposits, maps showing locations and general ages of these deposits, and a preliminary analysis with a number of figures summarizing many of the properties of these porphyry-style deposits. These summaries can be considered a new, quantified, form of most parts of descriptive models such as those in Cox and Singer (1986). The value of this information and analyses depends critically on the consistent manner of data gathering. For this reason, we first discuss the rules used in this compilation. Next the fields of the data file are considered. Finally, we discuss some of the things that can be done with the data.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr02268","usgsCitation":"Singer, D.A., Berger, V.I., and Moring, B.C., 2002, Porphyry copper deposits of the world: Database, maps, and preliminary analysis: U.S. Geological Survey Open-File Report 2002-268, Report: 61 p.; 6 Plates 48.00 inches x 36.00 inches or smaller; Data Files, https://doi.org/10.3133/ofr02268.","productDescription":"Report: 61 p.; 6 Plates 48.00 inches x 36.00 inches or smaller; Data Files","additionalOnlineFiles":"Y","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":172385,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr02268.jpg"},{"id":283636,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2002/0268/pdf/map2.pdf","text":"Plate 2","linkFileType":{"id":1,"text":"pdf"}},{"id":283635,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2002/0268/pdf/map1.pdf","text":"Plate 1","linkFileType":{"id":1,"text":"pdf"}},{"id":283633,"rank":3,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/0268/","linkFileType":{"id":5,"text":"html"}},{"id":283634,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2002/0268/pdf/of02-268.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":283641,"rank":9,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2002/0268/pdf/map6.pdf","text":"Plate 6","linkFileType":{"id":1,"text":"pdf"}},{"id":283640,"rank":8,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2002/0268/pdf/map5.pdf","text":"Plate 5","linkFileType":{"id":1,"text":"pdf"}},{"id":283638,"rank":7,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2002/0268/pdf/map4.pdf","text":"Plate 4","linkFileType":{"id":1,"text":"pdf"}},{"id":283637,"rank":6,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2002/0268/pdf/map3.pdf","text":"Plate 3","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad6e4b07f02db683cc2","contributors":{"authors":[{"text":"Singer, Donald A. dsinger@usgs.gov","contributorId":5601,"corporation":false,"usgs":true,"family":"Singer","given":"Donald","email":"dsinger@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":222604,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Berger, Vladimir I.","contributorId":15246,"corporation":false,"usgs":true,"family":"Berger","given":"Vladimir","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":222605,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Moring, Barry C. 0000-0001-6797-9258 moring@usgs.gov","orcid":"https://orcid.org/0000-0001-6797-9258","contributorId":2794,"corporation":false,"usgs":true,"family":"Moring","given":"Barry","email":"moring@usgs.gov","middleInitial":"C.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":222603,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

During February 1999-March 2000, hydrologic, water-quality, and sediment-quality data were collected from each of the three bays to establish baseline conditions. Gage-height fluctuations closely matched open-water tidal fluctuations. Rainfall during February 1999-February 2000 was about 20 percent below the annual average. Specific conductance, pH, water temperature, and dissolved oxygen monitored at 30-minute intervals in Christmas Bay for 13 months showed seasonal variations typical of monitoring stations on the Texas Gulf Coast. Prevailing winds were from the southeast. Monthly water-quality sampling for 13 months showed that in each of the three bays concentrations of major ions were small, and most nutrient concentrations were at or less than minimum reporting levels; indicator bacteria counts were consistently higher in samples collected from Drum Bay. Several trace elements (sampled twice) were detected in small concentrations. The only organochlorine pesticides (sampled once) that were greater than minimum reporting levels were atrazine, deethylatrazine, metolachlor, and simazine. During February 29-March 29, 2000, three semipermeable membrane devices were deployed at the Christmas Bay monitoring station. Seven of 77 semivolatile organic compounds analyzed in the lipids from the devices were detected in minute amounts. Analyses of surficial bed sediment sampled once in each of the three bays yielded detections of a number of semivolatile organic compounds; all concentrations were less than 10 micrograms per liter and much less than the respective benchmark concentration for those compounds that have had a benchmark concentration established for the protection of aquatic life.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr0282","collaboration":"In cooperation with the Houston-Galveston Area Council","usgsCitation":"East, J., 2002, Hydrologic, water-quality, and sediment-quality data for the Christmas Bay system, Brazoria County, Texas, February 1999-March 2000: U.S. Geological Survey Open-File Report 2002-82, iii, 43 p., https://doi.org/10.3133/ofr0282.","productDescription":"iii, 43 p.","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":425578,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_52067.htm","linkFileType":{"id":5,"text":"html"}},{"id":9159,"rank":3,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/ofr02-082/","linkFileType":{"id":5,"text":"html"}},{"id":333407,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2002/ofr02-082/pdf/02-082.pdf","text":"Report","linkFileType":{"id":1,"text":"pdf"},"description":"Report"},{"id":178415,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr0282.JPG"}],"country":"United States","state":"Texas","county":"Brazoria County","otherGeospatial":"Bastrop Bay, Christmas Bay, Drum Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -95.8,\n              28.5\n            ],\n            [\n              -95.8,\n              29.7\n            ],\n            [\n              -94.5,\n              29.7\n            ],\n            [\n              -94.5,\n              28.5\n            ],\n            [\n              -95.8,\n              28.5\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a18e4b07f02db6051f3","contributors":{"authors":[{"text":"East, Jeffery W. jweast@usgs.gov","contributorId":1683,"corporation":false,"usgs":true,"family":"East","given":"Jeffery W.","email":"jweast@usgs.gov","affiliations":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"preferred":true,"id":242328,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Waterquality\r\neffects were determined by analysis of\r\nnutrients, chloride, chemical and biochemical oxygen\r\ndemand, and suspended sediment samples\r\nfrom three streams (Blue River, Brush Creek, and\r\nIndian Creek) in the basin as well as the determination\r\nof a suite of compounds known to be indicative\r\nof wastewater including antioxidants,\r\ncaffeine, detergent metabolites, antimicrobials,\r\nand selected over-the-counter and prescription\r\npharmaceuticals. Constituent loads were determined\r\nfor both hydrologic regimes and a measure\r\nof the relative water-quality impact of selected\r\nstream reaches on the Blue River and Brush Creek\r\nwas developed. Genetic fingerprint patterns of\r\nEscherichia coli bacteria from selected stream\r\nsamples were compared to a data base of knownsource\r\npatterns to determine possible sources of\r\nbacteria.\r\nWater quality in the basin was affected by\r\nwastewater during both base flows and stormflows;\r\nhowever, there were two distinct sources\r\nthat contributed to these effects. In the Blue River\r\nand Indian Creek, the nearly continuous discharge\r\nof treated wastewater effluent was the primary\r\nsource of nutrients, wastewater indicator compounds,\r\nand pharmaceutical compounds detected\r\nin stream samples. Wastewater inputs into Brush\r\nCreek were largely the result of intermittent stormflow\r\nevents that triggered the overflow of combined\r\nstorm and sanitary sewers, and the\r\nsubsequent discharge of untreated wastewater into\r\nthe creek. A portion of the sediment, organic matter,\r\nand associated constituents from these events\r\nwere trapped by a series of impoundments constructed\r\nalong Brush Creek where they likely continued\r\nto affect water quality during base flow.\r\nConcentrations and loads of most wastewater\r\nconstituents in the Blue River and Indian Creek were\r\nsignificantly greater than in Brush Creek, especially\r\nduring base flow. However, wastewater indicator\r\ncompound concentrations were sometimes greater\r\nin some Brush Creek stormflow samples. Selected\r\nstream reaches along the mid-portion of Brush\r\nCreek showed higher effects relative to other sites,\r\nprimarily because these sites were in impounded\r\nreaches with the greatest density of wastewater\r\ninputs, or had relatively small drainage areas.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri024107","usgsCitation":"Wilkison, D.H., Armstrong, D., and Blevins, D.W., 2002, Effects of wastewater and combined sewer overflows on water quality in the Blue River basin, Kansas City, Missouri and Kansas, July 1998-October 2000: U.S. Geological Survey Water-Resources Investigations Report 2002-4107, iv, 162 p., https://doi.org/10.3133/wri024107.","productDescription":"iv, 162 p.","costCenters":[{"id":396,"text":"Missouri Water Science Center","active":true,"usgs":true}],"links":[{"id":413784,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_52033.htm","linkFileType":{"id":5,"text":"html"}},{"id":8500,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/wri/wri02-4107/","linkFileType":{"id":5,"text":"html"}},{"id":172592,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Kansas, Missouri","city":"Kansas City","otherGeospatial":"Blue River basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -94.875,\n              38.750\n            ],\n            [\n              -94.875,\n              39.125\n            ],\n            [\n              -94.5667,\n              39.125\n            ],\n            [\n              -94.5667,\n              38.750\n            ],\n            [\n              -94.875,\n              38.750\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a26e4b07f02db60fc33","contributors":{"authors":[{"text":"Wilkison, Donald H. wilkison@usgs.gov","contributorId":3824,"corporation":false,"usgs":true,"family":"Wilkison","given":"Donald","email":"wilkison@usgs.gov","middleInitial":"H.","affiliations":[{"id":396,"text":"Missouri Water Science Center","active":true,"usgs":true}],"preferred":true,"id":222224,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Armstrong, Daniel J. armstron@usgs.gov","contributorId":3823,"corporation":false,"usgs":true,"family":"Armstrong","given":"Daniel J.","email":"armstron@usgs.gov","affiliations":[{"id":396,"text":"Missouri Water Science Center","active":true,"usgs":true}],"preferred":true,"id":222223,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Blevins, Dale W. dblevins@usgs.gov","contributorId":2729,"corporation":false,"usgs":true,"family":"Blevins","given":"Dale","email":"dblevins@usgs.gov","middleInitial":"W.","affiliations":[],"preferred":true,"id":222222,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The island contains about 2,500 acres of freshwater wetlands that are located in a variety of physical settings, have a wide range of hydroperiods, and are influenced to varying degrees by surface and ground water, rainwater, and seawater. In 1999-2000, the U.S. Geological Survey, in cooperation with the National Park Service, conducted a water-quality study of Cumberland Island National Seashore to document and interpret the quality of a representative subset of surface- and ground-water resources for management of the seashore's natural resources. As part of this study, historical ground-water, surface-water, and ecological studies conducted on Cumberland Island also were summarized. \r\n\r\nSurface-water samples from six wetland areas located in the upland area of Cumberland Island were collected quarterly from April 1999 to March 2000 and analyzed for major ions, nutrients, trace elements, and field water-quality constituents including specific conductance, pH, temperature, dissolved oxygen, alkalinity, tannin and lignin, and turbidity. In addition, water temperature and specific conductance were recorded continuously from two wetland areas located near the mean high-tide mark on the Atlantic Ocean beaches from April 1999 to July 2000. Fish and invertebrate communities from six wetlands were sampled during April and December 1999. The microbial quality of the near-shore Atlantic Ocean was assessed in seawater samples collected for 5 consecutive days in April 1999 at five beaches near campgrounds where most recreational water contact occurs. \r\n\r\nGround-water samples were collected from the Upper Floridan aquifer in April 1999 and from the surficial aquifer in April 2000 at 11 permanent wells and 4 temporary wells (drive points), and were analyzed for major ions, nutrients, trace elements, and field water-quality constituents (conductivity, pH, temperature, dissolved oxygen, and alkalinity). Fecal-coliform bacteria concentrations were measured, but not detected, in samples collected from two domestic water-supply wells. During the 12-month period from April 1999 to March 2000 when water-quality and aquatic-community samples were collected, rainfall was 12.93 inches below the 30-year average rainfall. \r\n\r\nConstituent concentrations were highly variable among the different wetlands during the study period. Rainfall and tidal surges associated with tropical storms and hurricanes substantially influenced water quantity and quality, particularly in wetland areas directly influenced by tidal surges. Although surface waters on Cumberland Island are not used as sources of drinking water, exceedances of U.S. Environmental Protection Agency primary and secondary standards for drinking water were noted for comparative purposes. A nitrate concentration of 12 milligrams per liter in one sample from Whitney outflow was the only exceedance of a maximum contaminant level. Secondary standards were exceeded in 26 surface-water samples for the following constituents: pH (10 exceedances), chloride (8), sulfate (5), total dissolved solids (4), iron (2), fluoride (1), and manganese (1). The total-dissolved-solids concentrations and the relative abundance of major ions in surface-water samples collected from wetlands on Cumberland Island provide some insight into potential sources of water and influences on water quality. Major-ion chemistries of water samples from Whitney Lake, Willow Pond, and South End Pond 3 were sodium-chloride dominated, indicating direct influence from rainwater, salt aerosol, or inundation of marine waters. The remaining wetlands sampled had low total-dissolved-solids concentrations and mixed major-ion chemistries--North Cut Pond 2A was magnesium-sodium-chloride-sulfate dominated and Lake Retta and the two beach outflows were sodium-calcium-bicarbonate-chloride dominated.

The effectiveness of a deep-sumped hooded catch basin, three 2-chambered 1,500-gallon oil-grit separators, and mechanized street sweeping in reducing sediment and associated constituents was examined along the Southeast Expressway (Interstate Route 93) in Boston, Massachusetts. Repeated observations of the volume and distribution of bottom material in the oil-grit separators, including data on particle-size distributions, were compared to data from bottom material deposited during the initial 3 years of operation. The performance of catch-basin hoods and the oil-grit separators in reducing floating debris was assessed by examining the quantity of material retained by each structural BMP compared to the quantity of material retained by and discharged from the oil-grit separators, which received flow from the catch basins. The ability of each structural BMP to reduce suspended-sediment loads was assessed by examining (a) the difference in the concentrations of suspended sediment in samples collected simultaneously from the inlet and outlet of each BMP, and (b) the difference between inlet loads and outlet loads during a 14-month monitoring period for the catch basin and one separator, and a 10-month monitoring period for the second separator. The third separator was not monitored continuously; instead, samples were collected from it during three visits separated in time by several months. Suspended-sediment loads for the entire study area were estimated on the basis of the long-term average annual precipitation and the estimated inlet and outlet loads of two of the separators. The effects of mechanized street sweeping were assessed by evaluating the differences between suspended-sediment loads before and after street sweeping, relative to storm precipitation totals, and by comparing the particle-size distributions of sediment samples collected from the sweepers to bottom-material samples collected from the structural BMPs. A mass-balance calculation was used to quantify the accuracy of the estimated sediment-removal efficiency for each structural BMP. The ability of each structural BMP to reduce concentrations of inorganic and organic constituents was assessed by determining the differences in concentrations between the inlets and outlets of the BMPs for four storms. The inlet flows of the separators were sampled during five storms for analysis of fecal-indicator bacteria. The particle-size distribution of bottom material found in the first and second chambers of the separators was similar for all three separators. Consistent collection of floatable debris at the outlet of one separator during 12 storms suggests that floatable debris were not indefinitely retained.Concentrations of suspended sediment in discrete samples of runoff collected from the inlets of the two separators ranged from 8.5 to 7,110 mg/L. Concentrations of suspended sediment in discrete samples of runoff collected from the outlets of the separators ranged from 5 to 2,170 mg/L. The 14-month sediment-removal efficiency was 35 percent for one separator, and 28 percent for the second separator. In the combined-treatment system in this study, where catch basins provided primary suspended-sediment treatment, the separators reduced the mass of the suspended sediment from the pavement by about an additional 18 percent. The concentrations of suspended sediment in discrete samples of runoff collected from the inlet of the catch basin ranged from 32 to 13,600 mg/L. Concentrations of suspended sediment in discrete samples of runoff collected from the outlet of the catch basin ranged from 25.7 to 7,030 mg/L. The sediment-removal efficiency for individual storms during the 14-month monitoring period for the deep-sumped hooded catch basin was 39 percent.The concentrations of 29 in","language":"ENGLISH","doi":"10.3133/wri024059","usgsCitation":"Smith, K.P., 2002, Effectiveness of three best management practices for highway-runoff quality along the Southeast Expressway, Boston, Massachusetts: U.S. Geological Survey Water-Resources Investigations Report 2002-4059, 62 p., one CD-ROM, https://doi.org/10.3133/wri024059.","productDescription":"62 p., one CD-ROM","costCenters":[],"links":[{"id":172590,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3544,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri024059","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4ae4b07f02db625299","contributors":{"authors":[{"text":"Smith, Kirk P. 0000-0003-0269-474X kpsmith@usgs.gov","orcid":"https://orcid.org/0000-0003-0269-474X","contributorId":1516,"corporation":false,"usgs":true,"family":"Smith","given":"Kirk","email":"kpsmith@usgs.gov","middleInitial":"P.","affiliations":[{"id":376,"text":"Massachusetts Water Science Center","active":true,"usgs":true},{"id":466,"text":"New England Water Science Center","active":true,"usgs":true}],"preferred":true,"id":222217,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The purpose of the group is the coordinate the activities of the many agencies active in Mars geodesy and cartography in order to minimize redundant effort and ensure that the products needed by mission customers are generated. A specific objectives has been to avoid repeating the experience of the 1970s-80s, when competing researchers produced geodetic control solutions and maps of Mars that were mutually inconsistent. To this end, the MGCWG has recently assembled a set of preferred values for Mars cartographic constants, based on the best available data. These values have been transmitted to the International Astronomical Union and appear in the report of the IAU/IAG Working Group on Cartographic Coordinates and Rotational Elements of the Planets and Satellites as the officially recommended constants for Mars (Seidelmann et al., 2002). The MGCWG has also recommended to NASA that the USGS adopt the IAU-approved coordinate system of planetocentric latitude and east longitude for future maps of Mars, in the place of the (also IAU-approved) planetographic system with west longitude positive. This recommendation has recently been approved by NASA. In this paper we present the preferred values for Mars cartographic constants with discussion of the process by which they were derived, then discuss the rationale and implications of the use of east/planetocentric coordinates in future Mars maps.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Geospatial Theory, Processing and Applications: ISPRS Commission IV Proceedings","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"Geospatial Theory, Processing and Applications: ISPRS Commission IV","conferenceDate":"July 9-12, 2002","conferenceLocation":"Ottawa, Canada","language":"English","publisher":"International Society for Photogrammetry and Remote Sensing","usgsCitation":"Duxbury, T.C., Kirk, R.L., Archinal, B.A., and Neumann, G., 2002, Mars Geodesy/Cartography Working Group recommendations on Mars cartographic constants and coordinate systems, <i>in</i> Geospatial Theory, Processing and Applications: ISPRS Commission IV Proceedings, Ottawa, Canada, July 9-12, 2002, 4 p.; DVD-ROM.","productDescription":"4 p.; DVD-ROM","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":360573,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":360572,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.isprs.org/proceedings/XXXIV/part4/"}],"otherGeospatial":"Mars","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5c1b66e8e4b0708288c71d42","contributors":{"authors":[{"text":"Duxbury, T.

Three of the Borrelly images have geometry suitable to photogrammetrically map the nucleus, which form two stereopairs with an expected precision (EP) of ~410 m and ~670 m each. DS1 team members at the USGS and DLR have independently produced digital elevation models (DEMs) of Borrelly. Automatic stereo-matching algorithms were used by both USGS and DLR, but the USGS DEM was additionally manually edited in stereo. We accomplished a quantitative statistical comparison of the DEMs and found they have a standard deviation of 120 m, which is small compared to the EP above. There are systematic differences, we estimate the stereomatching error to only 0.20 pixel RMS, which is similar to the level of subpixel matching accuracy obtained in a wide variety of other mapping situations. The resulting DEMs enable a variety of applications such as perspective views, photometric modeling and studies of the energy balance of the nucleus. We hope to use the USGS DEM as a starting point to extrapolate the shape of the hidden side of the nucleus. This would not only let us determine the volume and moments of inertia of the nucleus, but would lead to a calculation of the insolation onto the nucleus averaged over an entire orbit, and thence to a model of the evolution of nuclear shape.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Geospatial Theory, Processing and Applications: ISPRS Commission IV Proceedings","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"Geospatial Theory, Processing and Applications: ISPRS Commission IV","conferenceDate":"July 9-12, 2002","conferenceLocation":"Ottawa, Canada","language":"English","publisher":"International Society for Photogrammetry and Remote Sensing","usgsCitation":"Howington-Kraus, E., Kirk, R.L., Soderblom, L.A., Giese, B., and Oberst, J., 2002, USGS and DLR topographic mapping of Comet Borrelly, <i>in</i> Geospatial Theory, Processing and Applications: ISPRS Commission IV Proceedings, Ottawa, Canada, July 9-12, 2002, 5 p.; DVD-ROM.","productDescription":"5 p.; DVD-ROM","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":360569,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":360568,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.isprs.org/proceedings/XXXIV/part4/"}],"otherGeospatial":"Comet Borrelly","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5c1b66e8e4b0708288c71d48","contributors":{"authors":[{"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":754703,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"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":754704,"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":754705,"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":754706,"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":754707,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Common raven populations in the Mojave\nDesert have benefited by human-provided resources; they've expanded precipitously in recent\nyears. Because ravens prey on juveniles of the threatened desert tortoise, they have become the\nfocus of management concerns to help recover dwindling tortoise populations. I have outlined\nherein a series of management recommendations designed to reduce raven predation on desert\ntortoises thereby facilitating juvenile tortoise recruitment into the population of reproductive\nadults. The recommendations are based on the best available scientific information and are\nintended to provide a basis for a long-term reduction in raven impacts.</p>\n<br/>\n<p>The recommendations fall into four basic categories.  (1) Modify anthropogenic sources of food, water, and nesting substrates to reduce their use by ravens.  This includes modifying landfill operations, septage containment practices, livestock management, and other commercial and private practices that help facilitate raven survival and dispersal by providing food and water.  Most of these measures are long-term actions deigned to reduce the carrying capacity of the desert for ravens.  This action is critical and must be done over very large areas. (2)Lethal removal of ravens by shooting or euthanizing following live trapping.  Specific ravens known to prey on tortoises would be targeted as well as all ravens found foraging within specific high-priority desert tortoise management zones (e.g., Desert Tortoise Natural Areas, DTNA).  These actions would primarily be deployed on a short-term emergency basis to give specific tortoise populations a necessary boost until other measures become fully implemented and achieve their goals. (3) Conduct research on raven ecology, raven behavior, and methods to reduce raven predation on tortoises.  Results of these studies would be used to design future phases of the raven management program. (4) All actions should be approached within an adaptive management framework.  As such monitor, actions should be designed as experiments so that monitoring of actions will yield reliable and scientifically sound results.  Coordinating and oversight teams should be convened to facilitate cooperation and coordination among agencies and to ensure that the actions are being implemented effectively.</p>\n<br/>\n<p>Recommendations made herein were developed to help recover tortoise populations by reducing raven predation on juvenile tortoises.  If the recommendations made are implemented in concert with actions reducing other causes of mortality, ill health, and lowered reproductive output, they should aid in the long-term recovery of desert tortoise populations.  Many important aspects of raven population dynamics, raven predation on tortoises, and how to manage raven populations and behavior are as yet unknown.  Because of this, any raven management program must be implemented within an adaptive management framework.  Doing so would allow for sufficient flexibility to modify the program as new information is gained.</p>","language":"English","publisher":"U.S. Geological Survey, Western Ecological Research Center","publisherLocation":"Sacramento, CA","usgsCitation":"Boarman, W.I., 2002, Reducing predation by common ravens on desert tortoises in the Mojave and Colorado Deserts, iii, 33 p.","productDescription":"iii, 33 p.","numberOfPages":"39","costCenters":[],"links":[{"id":289197,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53b286f9e4b07b8813a554fa","contributors":{"authors":[{"text":"Boarman, William I.","contributorId":51683,"corporation":false,"usgs":true,"family":"Boarman","given":"William","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":354488,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

At the end of the exposure fish were spawned and the reproductive outcomes were assessed. TCDD was accumulated into tissues and eggs in a dose-dependent manner with steady state being achieved after 50–100 day of exposure. Biochemical and hematological parameters were monitored at 50, 100, 150, and 200 day after the beginning of exposure. The survival of adult female trout was reduced in a dose-dependent manner by exposure to TCDD in the diet. Fish fed 1.8 ng TCDD/kg, moist weight of diet, showed significantly reduced survival compared with those fed the control diet. TCDD also affected survival of fry from females fed 1.8 ng TCDD/kg. Observed adverse effects in adult fish were as sensitive as early life-stage endpoints. Liver EROD activity was only moderately increased in all exposure groups after 250+ day of exposure. Low rates of edema and deformities were observed in fry from all treatment groups including controls. This study has demonstrated adverse effects of TCDD to both adults and fry at concentrations comparable to current environmental concentrations.

The Sparta aquifer in north-central Louisiana is the fourth most heavily pumped aquifer in the State. Approximately 68.2 Mgal/d was withdrawn in 2000. Water levels in the aquifer declined to more than 200 feet below sea level in the Monroe area by 1997. During 1990-2000, water level declines ranged from 0.1 to 5.2 ft/yr at monitor wells screened in the aquifer. The Southern Hills aquifer system of southeastern Louisiana is composed of numerous freshwater aquifers. This aquifer system is the third most heavily pumped aquifer or aquifer system in the State (291 Mgal/d in 2000). By the 1970's saltwater encroachment had been documented in major aquifers in the Baton Rouge area. Water levels in deep aquifers having largest withdrawals declined about 0.2 to 3.5 ft/yr or more during the period 1990-2000. In 2000, about 84 percent (8,700 Mgal/d) of the water withdrawn in Louisiana was surface water. Stream discharge data were analyzed for 59 continuous discharge stations. Eleven stations on nine streams had decreasing mean annual discharge during the period 1990-2000.</span></p>","language":"English","publisher":"Louisiana Department of Transportation and Development, Office of Public Works ","publisherLocation":"Baton Rouge, LA","issn":"0161-6986 ","usgsCitation":"Tomaszewski, D.J., Lovelace, J.K., and Ensminger, P.A., 2002, Water withdrawals and trends in ground-water levels and stream discharge in Louisiana: Technical Report, v. 68.","costCenters":[],"links":[{"id":335715,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Louisiana","volume":"68","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58a6c83ce4b025c4642862e4","contributors":{"authors":[{"text":"Tomaszewski, Dan J.","contributorId":95544,"corporation":false,"usgs":true,"family":"Tomaszewski","given":"Dan","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":669658,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lovelace, John K. 0000-0002-8532-2599 jlovelac@usgs.gov","orcid":"https://orcid.org/0000-0002-8532-2599","contributorId":999,"corporation":false,"usgs":true,"family":"Lovelace","given":"John","email":"jlovelac@usgs.gov","middleInitial":"K.","affiliations":[{"id":369,"text":"Louisiana Water Science Center","active":true,"usgs":true},{"id":24708,"text":"Lower Mississippi-Gulf Water Science Center","active":true,"usgs":true}],"preferred":true,"id":669659,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ensminger, Paul A. 0000-0002-0536-0369 paensmin@usgs.gov","orcid":"https://orcid.org/0000-0002-0536-0369","contributorId":4754,"corporation":false,"usgs":true,"family":"Ensminger","given":"Paul","email":"paensmin@usgs.gov","middleInitial":"A.","affiliations":[{"id":24708,"text":"Lower Mississippi-Gulf Water Science Center","active":true,"usgs":true}],"preferred":true,"id":669660,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
