During this period, five rainfall samples were collected and analyzed for selected nutrients. Ten runoff samples from nine runoff events were collected at the three watershed monitoring stations. Runoff samples were analyzed for selected nutrients, major ions, trace elements, pesticides, and bacteria.</p><p>Study area rainfall during 2000 and 2001 was 33.27 and 28.20 inches, respectively, less than the long-term average annual of 36.31 inches. Total runoff from the study area watersheds during 2000–2001 was 2.46 inches; the regional average is about 2 inches per year. Rainfall and runoff during the study period was typical of historical patterns, with periods of below average rainfall interspersed with extreme events. Three individual storm events accounted for about 29 percent of the total rainfall and 86 percent of the total runoff during 2000– 2001.</p><p>Runoff concentrations of nutrients, major ions, and trace elements generally were larger in the mixed agricultural watershed than runoff concentrations in the rangeland watersheds. Pesticides were detected in two of eight runoff samples. Three pesticides (atrazine, deethylatrazine, and trifluralin) were detected in very small concentrations; only deethylatrazine was detected in a concentration greater than the laboratory minimum reporting level.</p><p>Bacteria in agricultural and rangeland runoff is a potential water-quality concern as all fecal coliform and <i>E. coli</i> densities in the runoff samples exceeded Texas Surface Water Quality Standards for receiving waters. However, runoff and relatively large bacteria densities represent very brief and infrequent conditions, and the effect on downstream water is not known.</p><p>Rainfall deposition is a major source of nitrogen delivered to the study area. Rainfall nitrogen (mostly ammonia and nitrate) exceeded the runoff yield. The average annual rainfall deposition of total nitrogen on the study area watersheds was 1.3 pounds per acre. In contrast, an average annual yield of 0.57 and 0.21 pound per acre of total nitrogen in runoff exited the mixed agricultural watershed and the rangeland watersheds, respectively.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr02291","collaboration":"In cooperation with the U.S. Department of Agriculture, Natural Resources Conservation Service; San Patricio Soil and Water Conservation District; and The Welder Wildlife Foundation","usgsCitation":"Ockerman, D.J., 2002, Hydrologic conditions and quality of rainfall and storm runoff in agricultural and rangeland areas in San Patricio County, Texas, 2000-2001: U.S. Geological Survey Open-File Report 2002-291, Report: iv, 20 p.; 1 Plate, https://doi.org/10.3133/ofr02291.","productDescription":"Report: iv, 20 p.; 1 Plate","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":177102,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr02291.JPG"},{"id":333398,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2002/ofr02-291/pdf/02-291.pdf","text":"Report","size":"609 KB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"},{"id":4573,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr02-291/","linkFileType":{"id":5,"text":"html"}},{"id":333399,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2002/ofr02-291/02-291_plate.jpg","text":"Plate 1","size":"809 KB jpg","description":"Plate 1"}],"country":"United States","state":"Texas","county":"San Patricio County","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -97.8,\n              28\n            ],\n            [\n              -97.8,\n              28.3\n            ],\n            [\n              -97.1,\n              28.3\n            ],\n            [\n              -97.1,\n              28\n            ],\n            [\n              -97.8,\n              28\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a2de4b07f02db614417","contributors":{"authors":[{"text":"Ockerman, Darwin J. 0000-0003-1958-1688 ockerman@usgs.gov","orcid":"https://orcid.org/0000-0003-1958-1688","contributorId":1579,"corporation":false,"usgs":true,"family":"Ockerman","given":"Darwin","email":"ockerman@usgs.gov","middleInitial":"J.","affiliations":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"preferred":true,"id":242318,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Generally, the highest concentrations were measured in the Alamo River. The concentrations of carbaryl, chlorpyrifos, cycloate, dacthal, diazinon, and eptam were highest in samples collected in autumn 1996. In contrast, the concentrations of atrazine, carbofuran, and malathion were highest in samples collected in late winter/early spring 1997.

The sampling site is strategically placed within a highly managed canal system that exhibits low and rapidly changing water conditions. With the ADCP and ADVM, flow can be gaged more accurately rather than by conventional field-data collection methods. \r\n\r\nAn ADVM velocity rating relates measured velocity determined by the ADCP (dependent variable) with the ADVM velocity (independent variable) by means of regression analysis techniques. The coefficient of determination (R2) for this rating is 0.99 at the sampling site. Concentrations and loads of total phosphorus, total Kjeldahl nitrogen, and total nitrogen (dependent variables) were related to instantaneous discharge, acoustic backscatter, stage, or water temperature (independent variables) recorded at the time of sampling. Only positive discharges were used for this analysis. Discharges less than 100 cubic feet per second generally are considered inaccurate (probably as a result of acoustic ray bending and vertical temperature gradients in the water column). \r\n\r\nOf the concentration models, only total phosphorus was statistically significant at the 95-percent confidence level (p-value less than 0.05). Total phosphorus had an adjusted R2 of 0.93, indicating most of the variation in the concentration can be explained by the discharge. All of the load models for total phosphorus, total Kjeldahl nitrogen, and total nitrogen were statistically significant. Most of the variation in load can be explained by the discharge as reflected in the adjusted R2 for total phosphorus (0.98), total Kjeldahl nitrogen (0.99), and total nitrogen (0.99).","language":"ENGLISH","doi":"10.3133/ofr02285","usgsCitation":"Lietz, A., 2002, Feasibility of Estimating Constituent Concentrations and Loads Based on Data Recorded by Acoustic Instrumentation: U.S. Geological Survey Open-File Report 2002-285, 10 p.

Important conventional oil and gas resources have been discovered and produced from reservoirs ranging in age from Cambrian through Tertiary (Law, 1996). In addition, an extensive overpressured basin - centered gas accumulation has also been identified in Cretaceous and Tertiary reservoirs by numerous researchers including Law (1984a, 1996), Law and others (1980, 1989), McPeek (1981), and Spencer (1987). The purpose of this report is to present new vitrinite reflectance data to be used in support of the U.S Geological Survey assessment of undiscovered oil and gas resources of the Greater Green River Basin. One hundred eighty-six samples were collected from Cretaceous and Tertiary coalbearing strata (figs. 1 and 2) in an effort to better understand and characterize the thermal maturation and burial history of potential source rocks. Two samples were from core, one from outcrop, and the remainder from well cuttings. These data were collected to supplement previously published data by Law (1984b), Pawlewicz and others (1986), Merewether and others (1987), and Garcia-Gonzalez and Surdam (1995) and are presented in table 1. </p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr02339","usgsCitation":"Pawlewicz, M.J., and Finn, T.M., 2002, Vitrinite reflectance data for the Greater Green River basin, southwestern Wyoming, northwestern Colorado, and northeastern Utah: U.S. Geological Survey Open-File Report 2002-339, 16 p., https://doi.org/10.3133/ofr02339.","productDescription":"16 p.","costCenters":[],"links":[{"id":170551,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3608,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/ofr-02-0339/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Colorado, Utah, Wyoming","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fdb36","contributors":{"authors":[{"text":"Pawlewicz, Mark J. pawlewicz@usgs.gov","contributorId":752,"corporation":false,"usgs":true,"family":"Pawlewicz","given":"Mark","email":"pawlewicz@usgs.gov","middleInitial":"J.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":222559,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Finn, Thomas M. 0000-0001-6396-9351 finn@usgs.gov","orcid":"https://orcid.org/0000-0001-6396-9351","contributorId":778,"corporation":false,"usgs":true,"family":"Finn","given":"Thomas","email":"finn@usgs.gov","middleInitial":"M.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":222560,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Because of the dating methods in those studies, it was impossible to precisely define rates of change. The present study provides historic age control. A pair of small harbor structures were constructed in the early 1950's at Chesapeake Beach, MD to maintain a dredged channel to a small marina occupying a ravine in the Calvert Cliffs. Prior to construction, this section of shoreline was comprised of eroding steep bluffs cut into Miocene-age sediments. Downdrift erosion is now apparent south of the structures as is updrift deposition behind the northern jetty. Since construction the updrift sand body has prograded northward and progressively deposited protective beaches along the toes of the bluffs. Former eroding bluffs nearest the harbor are now stable, vegetated slopes at angles near 35 degrees. Slope angles widen to the north and to the northern limit of the sand body. Beyond this are eroding bluffs standing at angles of 70-80 degrees. The relative time required for eroding bluffs to reach stability is estimated by interpolating the distance and time for the sand body to prograde northward since harbor construction. We measured slope angles at intervals northward from the updrift structure for a distance of 2000 feet. A least squares regression of slope angle vs distance showed progressive decrease in angle from north to south. Actively eroding 70-80 degree bluffs gave way to vegetated, but slumping slopes, and finally to stable 35-degree slopes at the harbor. A relationship between time and distance along the shore allowed us to estimate a stabilization time for this location of 35-40 years. The shortness of this time scale allows us to suggest that attempts to artificially stabilize eroding bluffs along this coast is not a simple task of protecting the toes of slopes from wave action. Once shoreline retreat ends, sloughing of sediment from bluff faces gives way to longer-term landslide processes. The bluff top recedes until a stable 35-degree slope is attained. Thus, simple shoreline protection methods may not preserve property at the bluff edge.","language":"ENGLISH","doi":"10.3133/ofr02331","usgsCitation":"Clark, I.E., Larsen, C.E., and McRae, M., 2002, Historic bluff retreat and stabilization at Flag Harbor, Chesapeake Bay, Maryland: U.S. Geological Survey Open-File Report 2002-331, 1 over-size sheet., https://doi.org/10.3133/ofr02331.","productDescription":"1 over-size sheet.","costCenters":[],"links":[{"id":170488,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3606,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/of02-331/ ","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a58e4b07f02db62eea1","contributors":{"authors":[{"text":"Clark, Inga E. 0000-0003-0084-0256 iclark@usgs.gov","orcid":"https://orcid.org/0000-0003-0084-0256","contributorId":3256,"corporation":false,"usgs":true,"family":"Clark","given":"Inga","email":"iclark@usgs.gov","middleInitial":"E.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"preferred":true,"id":222553,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Larsen, Curtis E.","contributorId":37731,"corporation":false,"usgs":true,"family":"Larsen","given":"Curtis","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":222554,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McRae, Michele","contributorId":85249,"corporation":false,"usgs":true,"family":"McRae","given":"Michele","affiliations":[],"preferred":false,"id":222555,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Associated with the arsenic are elevated levels of metals such as lead, cadmium and mercury. Potential sources of this contamination include waste from smelters in the area and commercial herbicide containing arsenic trioxide and lead arsenate (USEPA, 1999). As a part of the U.S. Environmental Protection Agency’s Vasquez Boulevard-I-70 Project (VBI70 project; USEPA, 1999), lead isotopic analyses of selected soil samples, smelter waste, and a commercial herbicide and a commercial lead arsenate pesticide have been performed in order to constrain the possible sources of elevated lead, and by proxy arsenic, found in these residential soils. The isotopes of lead can be used as a natural tracer in determining sources of contaminants in soils and stream sediments (e.g. Church and others, 1997; Fey and others, 1999; Unruh and others, 2000). The element lead (Pb) consists of four naturally occurring and stable isotopes, 204Pb, 206Pb, 207Pb, and 208Pb. Three of these, 206Pb, 207Pb, and 208Pb are radiogenic decay products of naturally occurring 238U, 235U, and 232Th, respectively. Owing to variations among the U/Pb and Th/Pb elemental abundance ratios among different types of geologic materials, variations in the relative abundances of the Pb isotopes are produced among different materials during geologic time. In order for the Pb isotope method to be useful for determining possible contaminant sources, two important criteria must be met (e.g. Church and others 1997): (1) It must be possible to obtain and measure the Pb isotopic compositions in all potential contaminant sources and in uncontaminated material and (2) the Pb isotopic compositions of the potential contaminant sources must be distinctly different from one another and from uncontaminated background. Variations among the Pb isotopic ratios in selected samples can be correlated with potential sources of Pb with known isotopic compositions in order to determine the relative contribution of Pb from a specific source to the sample. The purpose of this study is to use Pb isotopic data obtained from a selected subset of samples to determine the Pb isotopic signatures of uncontaminated soils as well as those of potential sources of contamination. The data will eventually be used in conjunction with other geochemical data to help determine which source or sources of contamination are most likely responsible for the elevated arsenic levels in the residential soils. </p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr02321","usgsCitation":"Unruh, D., 2002, Lead isotopic analyses of selected soil samples from the USEPA Vasquez Blvd.-I-70 study area, Denver, CO: U.S. Geological Survey Open-File Report 2002-321, 57 p., https://doi.org/10.3133/ofr02321.","productDescription":"57 p.","costCenters":[],"links":[{"id":170486,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3604,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/ofr-02-0321/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Colorado","city":"Denver","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1be4b07f02db6a8973","contributors":{"authors":[{"text":"Unruh, D.M.","contributorId":8498,"corporation":false,"usgs":true,"family":"Unruh","given":"D.M.","email":"","affiliations":[],"preferred":false,"id":222548,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Actively eroding coastal bluffs along the western shore of the Chesapeake Bay provide a key for understanding the centennial-scale development of stable slopes from eroding bluff faces. The Calvert Cliffs are composed of sandy silts, silty sands, and clayey silts of Miocene-age. Active wave erosion at the bluff toes encourages rapid sloughing from bluff faces and maintains slope angles of 70-80 degrees and relatively constant bluff-retreat rates. Naturally stabilized slopes are preserved as a fossil bluff line inland from a prograding cuspate foreland at Cove Point. The foreland is migrating southward at a rate of ca. 1.5 m/yr. As it moves south, it progressively protects bluffs from wave action as new beaches are deposited at their toes. Wave erosion is reinitiated at the northern end of the complex as the landform passes. An incremental record of slope change is preserved along the fossil bluff line. 14C dating of swales between beach ridges shows the complex to span 1700 years of progressive migration history. We hypothesized that slopes would change from steep, eroding faces to low-angle slopes covered with vegetation and sought to document the rate of change. Our team measured slope angles at intervals along the fossil bluff line and dated profiles by interpolating 14C ages of adjacent beach ridges. There was no progressive decrease in slope with age. All slopes along the fossil bluff line were 30-40 degrees with a mean of 35 degrees. Constancy in slope angle suggests that steep, actively eroding bluffs were quickly changed to stable slopes by landslides and slumping once they were protected. Given the accuracy of our age control, we conclude that the time required to attain a stable slope under natural processes is less than one century. This indicates that once toe erosion is ended (naturally or through engineering) slopes are reduced to 35-degrees over a period of decades and not centuries.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr02332","usgsCitation":"Herzog, M., Larsen, C.E., and McRae, M., 2002, Slope evolution at the Calvert Cliffs, Maryland — Measuring the change from eroding bluffs to stable slopes: U.S. Geological Survey Open-File Report 2002-332, 1 Plates: 68.18 × 34.17 inches, https://doi.org/10.3133/ofr02332.","productDescription":"1 Plates: 68.18 × 34.17 inches","costCenters":[],"links":[{"id":170550,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3607,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/of02-332/","linkFileType":{"id":5,"text":"html"}},{"id":409818,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_52772.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Maryland","otherGeospatial":"Calvert Cliffs","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -76.53195085440566,\n              38.509545743938475\n            ],\n            [\n              -76.53195085440566,\n              38.37767482554915\n            ],\n            [\n              -76.3957317471505,\n              38.37767482554915\n            ],\n            [\n              -76.3957317471505,\n              38.509545743938475\n            ],\n            [\n              -76.53195085440566,\n              38.509545743938475\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f1e4b07f02db5ee99c","contributors":{"authors":[{"text":"Herzog, Martha","contributorId":65525,"corporation":false,"usgs":true,"family":"Herzog","given":"Martha","email":"","affiliations":[],"preferred":false,"id":222557,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Larsen, Curtis E.","contributorId":37731,"corporation":false,"usgs":true,"family":"Larsen","given":"Curtis","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":222556,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McRae, Michele","contributorId":85249,"corporation":false,"usgs":true,"family":"McRae","given":"Michele","affiliations":[],"preferred":false,"id":222558,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Trout stocked in the Snake River for\r\nrecreational purposes do not survive through the winter. Sediment cores analyzed by previous\r\ninvestigators from the reservoir revealed elevated concentrations of base metals and mercury. We\r\ncollected 36 surface water samples (filtered and unfiltered) and 38 streambed-sediment samples from\r\nstreams in the Snake River watershed. Analyses of the sediment and water samples show that\r\nconcentrations of several metals exceed aquatic life standards in one or both media. Ribbon maps\r\nshowing dissolved concentrations of zinc, cadmium, copper, and manganese in water (0.45-micron\r\nfiltered and corrected for the ameliorating effect of hardness), and copper, cadmium, and zinc in sediment\r\nindicate reaches where toxic effects on trout would be expected and stream reaches where toxicity\r\nstandards for rainbow, brown, and brook trout are exceeded.\r\nInstantaneous loads for sulfate, strontium, iron, cadmium, copper, and zinc were calculated from\r\n0.45-micron-filtered water concentrations and discharge measurements were made at each site. Sulfate\r\nand strontium behave conservatively, whereas copper, cadmium, and zinc are reactive. The dissolved\r\ncopper load entering the reservoir is less than 20 percent of the value calculated from some upper reaches;\r\ncopper is transferred to suspended and or streambed sediment by sorption to iron oxyhydroxides. Higher\r\npercentages of zinc and cadmium reach the reservoir in dissolved form; however, load calculations\r\nindicate that some of these metals are also precipitated out of solution. The most effective remediation\r\nactivities should be concentrated on reducing the dissolved loads of zinc, cadmium, and copper in two\r\nreaches of lower Peru Creek between the confluence with the Snake River and Cinnamon Gulch.\r\nWe analyzed all streambed sediment for mercury and selected streambed-sediment and reservoir\r\ncore samples for lead isotope signatures.

Polyethylene-membrane vapor-diffusion (PVD) samplers were installed in river-bottom sediments to determine if PVD samplers provide an alternative to ground-water sampling from well points for identifying areas of detectable concentrations of contaminants in sediment pore water near the ground-water and surface-water interface. In August and September 2000, the PVD samplers were installed near well points at depths of 8 to 12 inches in both fine and coarse sediments, whereas the well points were installed at depths of 1 to 5 feet in coarse sediments only.\r\rComparison between vapor and water samples at 29 locations upstream from Mill Pond show that VOC vapor concentrations from PVD samplers in coarse river-bottom sediments are more likely to correspond to ground-water concentrations from well points than PVD samplers installed in fine sediments. Significant correlations based on Kendall's Tau were shown between vapor and ground-water concentrations for trichloroethylene and chlorobenzene for PVD samplers installed in coarse sediments where the fine organic layer that separated the two sampling depths was 1 foot or less in thickness.\r\rVOC concentrations from vapor samples also were compared to VOC, SVOC, and metals concentrations from ground-water samples at 10 well points installed upstream and downstream from Mill Pond, and in the former mill raceway. Chlorobenzene vapor concentrations correlated significantly with ground-water concentrations for 5 VOCs, 2 SVOCs, and 10 metals. Trichloroethylene vapor concentrations did not correlate with any of the other ground-water constituents analyzed at the 10 well points. Chlorobenzene detected by use of PVD samplers appears to be a strong indicator of the presence of VOCs, SVOCs, and metals in ground water sampled from well points at this site.\r\rResults from PVD samplers indicate that contaminant concentrations in water from well points installed 1 to 5 ft below fine sediments may not reflect concentrations in pore water less than 1 foot below the river bottom. There is insufficient information available to determine if VOC concentrations detected in PVD samplers are useful for identifying detectable aqueous concentrations of SVOCs and metals in sediment pore water at this site. Samples of pore water from a similar depth as PVD samplers are needed for confirmation of this objective.","language":"ENGLISH","doi":"10.3133/ofr02143","usgsCitation":"Campbell, J., Lyford, F.P., and Willey, R.E., 2002, Comparison of vapor concentrations of volatile organic compounds with ground-water concentrations of selected contaminants in sediments beneath the Sudbury River, Ashland, Massachusetts, 2000: U.S. Geological Survey Open-File Report 2002-143, iv, 33 p. : ill., maps ; 28 cm. , https://doi.org/10.3133/ofr02143.","productDescription":"iv, 33 p. : ill., maps ; 28 cm.

The image used for the base of this map represents more than 600 million measurements gathered between 1999 and 2001, adjusted for consistency (Neumann and others, 2001, 2002) and converted to planetary radii. These have been converted to elevations above the areoid as determined from a martian gravity field solution GMM2 (Lemoine and others, 2001), truncated to degree and order 50, and oriented according to current standards (see below). The average accuracy of each point is originally ~100 meters in horizontal position, and ~1 meter in radius (Neumann, 2001). However, the total elevation uncertainty is at least +3 m due to the global error in the areoid (+1.8 meters according to Lemoine and others, 2001) and regional uncertainties in its shape (communication from Neumann, 2002). The measurements were converted into a digital elevation model (DEM) (communication from Neumann, 2002; Neumann and others, 2001; Smith and others, 2001) using Generic Mapping Tools software (Wessel and Smith, 1998), with a resolution of 0.015625 degrees per pixel or 64 pixels per degree. In projection, the pixels are 926.17 meters in size at the equator.\n\nPROJECTION\n\nThe Mercator projection is used between latitudes +57°, with a central meridian at 0° and latitude equal to the nominal scale at 0°. The Polar Stereographic projection is used for the polar regions north of the +55° parallel and south of the –55° parallel with a central meridian set for both at 0°. The adopted equatorial radius is 3,396.19 km (Duxbury and others 2002; Seidelmann and others 2002).\n\nCOORDINATE SYSTEM\n\nThe MOLA data were initially referenced to an internally consistent inertial coordinate system, derived from tracking of the MGS spacecraft. By adopting appropriate values for the orientation of Mars as defined by the International Astronomical Union (IAU) and the International Association of Geodesy (IAG) (Seidelmann and others, 2002), these inertial coordinates were converted into the planet-fixed coordinates (longitude and latitude) used on this map. These values include the orientation of the north pole of Mars (including the effects of precession), the rotation rate of Mars, and a value for W0 of 176.630°, where W0 is the angle along the equator to the east, between the 0° meridian and the equator's intersection with the celestial equator at the standard epoch J2000.0 (Seidelmann and others, 2002). This value of W0 was chosen (Duxbury and others, 2002) in order to place the 0° meridian through the center of the small (~500 m) crater Airy-0, located in the crater Airy (de Vaucouleurs and others, 1973; Seidelmann and others, 2002). Longitude increases to the east, and latitude is planetocentric as allowed by IAU/IAG standards (Seidelmann and others, 2002) and in accordance with current NASA and USGS standards (Duxbury and others, 2002). A secondary grid (printed in red) has been added to the map as a reference to the west longitude/planetographic latitude system that is also allowed by IAU/IAG standards (Seidelmann and others, 2002) and has also been used for Mars. The figure adopted to compute this secondary grid is an oblate spheroid with an equatorial radius of 3,396.19 km and a polar radius of 3,376.2 km (Duxbury and others, 2002; Seidelmann and others, 2002).\n\nMAPPING TECHNIQUES\n\nTo create the topographic base image, the original DEM produced by the MOLA team in Simple Cylindrical projection with a resolution of 64 pixels per degree was projected into the Mercator and Polar Stereographic pieces. A shaded relief was generated from each DEM with a sun angle of 30° from horizontal and a sun azimuth of 270°, as measured clockwise from north, and a vertical exaggeration of 100%. Illumination is from the west, which follows a long-standing USGS tradition for planetary maps. This allows for continuity in the shading between maps and quadrangles, and most closely resembles lighting conditions found on imagery. The DEM values were then mapped to a smooth global color look-up table. Note that the chosen color scheme simply represents elevation changes and is not intended to imply anything about surface characteristics (e.g., past or current presence of water or ice). These two files were then merged and scaled to 1:25 million for the Mercator portion and 1:15,196,708 for the two Polar Stereographic portions, with a resolution of 300 dots per inch. The projections have a common scale of 1:13,923,113 at +56° latitude.\n\nNOMENCLATURE\n\nNames on this sheet are approved by the IAU and have been applied for features clearly visible at the scale of this map. For a complete list of the IAU-approved nomenclature for Mars, see the Gazetteer of Planetary Nomenclature at http://planetarynames.wr.usgs.gov/. Font color was chosen for readability. Names followed by an asterisk are provisionally approved.\n\n*M 25M RKN: Abbreviation for Mars, 1:25,000,000 series, shaded relief (R), with color (K) and nomenclature (N) (Greeley and Batson, 1990)","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr02282","usgsCitation":"Water Resources Division, U.S. Geological Survey, 2002, Topographic map of Mars M 25M RKN: U.S. Geological Survey Open-File Report 2002-282, Map: 36.00 inches x 34.00 inches, https://doi.org/10.3133/ofr02282.","productDescription":"Map: 36.00 inches x 34.00 inches","additionalOnlineFiles":"N","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":169765,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr02282.jpg"},{"id":3593,"rank":100,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2002/0282/pdf/of02-282.pdf","linkFileType":{"id":5,"text":"html"}},{"id":283768,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/0282/"}],"scale":"250000","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699881","contributors":{"authors":[{"text":"Water Resources Division, U.S. Geological Survey","contributorId":128075,"corporation":true,"usgs":false,"organization":"Water Resources Division, U.S. Geological Survey","id":529928,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The original paper map has been faithfully reproduced as a geologic map database for use in a GIS, and thus does not contain updated geologic information for the map area. This publication consists of three parts:\n\nDocumentation 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.\nThree 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.\nPlottable 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.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr02272","usgsCitation":"Wilshire, H.G., Bedford, D., and Coleman, T., 2002, Digital version of \"Open-File Report 92-181: Geologic map of the Indian Spring quadrangle, San Bernardino County, California\": U.S. Geological Survey Open-File Report 2002-272, Report: 27 p.; 1 Plate: 22.00 × 32.00 inches; Metadata, https://doi.org/10.3133/ofr02272.","productDescription":"Report: 27 p.; 1 Plate: 22.00 × 32.00 inches; Metadata","additionalOnlineFiles":"Y","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":172485,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr02272.jpg"},{"id":283713,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2002/0272/pdf/of02-272_3a.pdf","text":"Plate 1","linkFileType":{"id":1,"text":"pdf"}},{"id":3626,"rank":5,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/0272/","linkFileType":{"id":5,"text":"html"}},{"id":283712,"rank":3,"type":{"id":16,"text":"Metadata"},"url":"https://pubs.usgs.gov/of/2002/0272/of02-272_1b.html"},{"id":283711,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2002/0272/pdf/of02-272_1a.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"24000","country":"United States","state":"California","county":"San Bernardino County","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -115.875,35.125 ], [ -115.875,35.250 ], [ -115.750,35.250 ], [ -115.750,35.125 ], [ -115.875,35.125 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a82e4b07f02db64ae6e","contributors":{"authors":[{"text":"Wilshire, Howard G.","contributorId":68346,"corporation":false,"usgs":true,"family":"Wilshire","given":"Howard","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":222611,"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":222609,"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":222610,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
