This CD-ROM contains stacked, migrated, 2-Dimensional seismic reflection data and associated support information for 22 regional seismic lines (3,470 line-miles) recorded in the National Petroleum Reserve – Alaska (NPRA) from 1974 through 1981. Together, these lines constitute about one-quarter of the seismic data collected as part of the Federal Government’s program to evaluate the petroleum potential of the Reserve. The regional lines, which form a grid covering the entire NPRA, were created by combining various individual lines recorded in different years using different recording parameters. These data were reprocessed by the USGS using modern, post-stack processing techniques, to create a data set suitable for interpretation on interactive seismic interpretation computer workstations. Reprocessing was done in support of ongoing petroleum resource studies by the USGS Energy Program.
The CD-ROM contains the following files: 1) 22 files containing the digital seismic data in standard, SEG-Y format; 2) 1 file containing navigation data for the 22 lines in standard SEG-P1 format; 3) 22 small scale graphic images of each seismic line in Adobe Acrobat® PDF format; 4) a graphic image of the location map, generated from the navigation file, with hyperlinks to the graphic images of the seismic lines; 5) an ASCII text file with cross-reference information for relating the sequential trace numbers on each regional line to the line number and shotpoint number of the original component lines; and 6) an explanation of the processing used to create the final seismic sections (this document).
The SEG-Y format seismic files and SEG-P1 format navigation file contain all the information necessary for loading the data onto a seismic interpretation workstation.

Trends were estimated by use of either linear regression, Seasonal Kendall, or Kendall-Theil tests. Trends were reported for monthly-mean flow, monthly load, flow-adjusted concentration, and flow-weighted concentration. Mean yields and median concentrations were calculated to help assess current water-quality status and to facilitate comparisons between basins. The trend in flow was upward at 12 of the 30 sites. Trends of nutrient and sediment load were upward at these same 12 sites. Trends in flow-adjusted and flow-weighted concentrations varied by species. Trends in flow-weighted concentrations were generally upward or not significant for the nitrogen species and parallel or not significant for phosphorus species. Trends in flow-adjusted concentrations were downward at nearly all sites for sediment and dissolved solids in the Susquehanna and Potomac River Basins and generally were not significant in the Virginia river basins.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99451","issn":"0094-9140","usgsCitation":"Langland, M.J., Blomquist, J., Sprague, L.A., and Edwards, R.E., 2000, Trends and status of flow, nutrients, and sediments for selected nontidal sites in the Chesapeake Bay Watershed, 1985-98: U.S. Geological Survey Open-File Report 99-451, iv, 17 p.; Appendices, https://doi.org/10.3133/ofr99451.","productDescription":"iv, 17 p.; Appendices","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":119053,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0451/report-thumb.jpg"},{"id":24581,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/0451/","linkFileType":{"id":5,"text":"html"}},{"id":51654,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0451/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Delaware;Maryl;New York;Pennsylvania;Virginia;West Virginia","otherGeospatial":"Susquehanna River Basin;Choptank River Basin;Western Shore River Basin;Patuxent River Basin;Potomac River Basin;Rappahannock River Basin;Mattaponi River Basin;Pamunkey River Basin;James River Basin;Appomattox River Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -81,36.75 ], [ -81,43 ], [ -74,43 ], [ -74,36.75 ], [ -81,36.75 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4affe4b07f02db697c91","contributors":{"authors":[{"text":"Langland, Michael J. 0000-0002-8350-8779 langland@usgs.gov","orcid":"https://orcid.org/0000-0002-8350-8779","contributorId":2347,"corporation":false,"usgs":true,"family":"Langland","given":"Michael","email":"langland@usgs.gov","middleInitial":"J.","affiliations":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"preferred":true,"id":187688,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blomquist, Joel D. jdblomqu@usgs.gov","contributorId":3774,"corporation":false,"usgs":true,"family":"Blomquist","given":"Joel D.","email":"jdblomqu@usgs.gov","affiliations":[{"id":374,"text":"Maryland Water Science Center","active":true,"usgs":true}],"preferred":false,"id":187689,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sprague, Lori A. 0000-0003-2832-6662 lsprague@usgs.gov","orcid":"https://orcid.org/0000-0003-2832-6662","contributorId":726,"corporation":false,"usgs":true,"family":"Sprague","given":"Lori","email":"lsprague@usgs.gov","middleInitial":"A.","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":27111,"text":"National Water Quality Program","active":true,"usgs":true},{"id":509,"text":"Office of the Associate Director for Water","active":true,"usgs":true}],"preferred":true,"id":187687,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Edwards, Robert E.","contributorId":69191,"corporation":false,"usgs":true,"family":"Edwards","given":"Robert","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":187690,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":22205,"text":"ofr200033 - 2000 - Synthetic Precipitation Leaching Procedure (SPLP) leachate chemistry data for solid mine-waste composite samples from southwestern New Mexico, and Leadville, Colorado","interactions":[],"lastModifiedDate":"2012-02-02T00:08:08","indexId":"ofr200033","displayToPublicDate":"2000-09-01T00:00:00","publicationYear":"2000","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2000-33","title":"Synthetic Precipitation Leaching Procedure (SPLP) leachate chemistry data for solid mine-waste composite samples from southwestern New Mexico, and Leadville, Colorado","docAbstract":"This report details chemistry data derived from leaching of mine-waste composite samples using a modification of E.P.A.

In some ways, there have been many changes and in some ways the notes have stayed much the same. Generally, I was satisfied that the notes were both comprehensive and fairly easy to read. The exercises using SSTEMP have been upgraded to reflect advances in the software. Some additional material was added to better cover contemporary thremistors, and some, but not all, weak transitions and incomplete sentences have been corrected. A comprehensive index was added in an attempt to make these notes as useful as possible, and a few telling quotes have been added for spice. The goal has been to make this set of notes as stand-alone as possible and keep the file size down to something that is easily downloadable over the Internet today (March 2000).

Although the distribution of the relevant vertical-control data is somewhat sparse, in both space and time, those data that we have recovered indicate that this uplift exceeded 0.10 m and peaked 20-25 km west of the 1994 epicenter. While our data also indicate that this deformational event must have occurred during the period 1978-1989, evidence based on the character and magnitude of misclosures developed from 1987 and 1989 surveys argue that the deformation occurred largely during the period 1987-1989. The preseismic vertical-displacement field that preceded the Northridge earthquake is similar in form and, less certainly, magnitude to that which preceded the Mw 6.7, 1971 San Fernando earthquake; other possible, but less significant southern California analogues include the deformational events that preceded the Mw 5.3, 1973 Point Mugu and Mw 5.9, 1987 Whittier Narrows earthquakes. The small but growing number of recognized aseismic deformational episodes that preceded small to moderate magnitude earthquakes in southern California suggests that the deployment of the dense array of continuously recording GPS receivers planned for southern California can be expected to detect and more accurately describe such events than was heretofore possible. Moreover, if the relation between the duration of these deformational anomalies and the magnitudes of any ensuing earthquakes can be much more clearly established, the near perfect temporal control on position afforded by GPS suggests that we may be on the threshold of a realistic earthquake warning system.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr002","issn":"0094-9140","usgsCitation":"Castle, R.O., Packard, R.F., and Dinitz, L.B., 2000, Height changes in the epicentral region preceding the January 17, 1994 Northridge earthquake: U.S. Geological Survey Open-File Report 2000-2, 16 p., https://doi.org/10.3133/ofr002.","productDescription":"16 p.","numberOfPages":"16","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":379,"text":"Menlo Park Science Center","active":false,"usgs":true}],"links":[{"id":1421,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/0002/","linkFileType":{"id":5,"text":"html"}},{"id":153689,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0002/report-thumb.jpg"},{"id":52145,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0002/pdf/of00-002.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"California","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -119.2981,33.6983 ], [ -119.2981,34.4996 ], [ -118.1994,34.4996 ], [ -118.1994,33.6983 ], [ -119.2981,33.6983 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db635df0","contributors":{"authors":[{"text":"Castle, Robert O.","contributorId":22741,"corporation":false,"usgs":true,"family":"Castle","given":"Robert","email":"","middleInitial":"O.","affiliations":[],"preferred":false,"id":188671,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Packard, Robert F.","contributorId":96583,"corporation":false,"usgs":true,"family":"Packard","given":"Robert","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":188672,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dinitz, Laura B. ldinitz@usgs.gov","contributorId":3332,"corporation":false,"usgs":true,"family":"Dinitz","given":"Laura","email":"ldinitz@usgs.gov","middleInitial":"B.","affiliations":[],"preferred":true,"id":188670,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":21913,"text":"ofr004 - 2000 - Leaching studies of schwertmannite-rich precipitates from the Animas River Headwaters, Colorado and Boulder River Headwaters, Montana","interactions":[],"lastModifiedDate":"2020-02-24T06:32:16","indexId":"ofr004","displayToPublicDate":"2000-08-01T00:00:00","publicationYear":"2000","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2000-4","title":"Leaching studies of schwertmannite-rich precipitates from the Animas River Headwaters, Colorado and Boulder River Headwaters, Montana","docAbstract":"No abstract available.

This area has a complex seafloor morphology and highly discontinuous shallow stratigraphy that are the result of deformation by the highly mobile Louann salt that underlies much of this margin shoreward of the Sigsbee Escarpment.Gas hydrates exist both on the sea floor and at depth throughout the gas hydrate stability zone which extends to several hundred meters beneath the sea floor at greater water depths. Multibeam bathymetry, GLORIA sidescan sonar imagery, and site-specific studies have identified the presence of faults, mass-wasting deposits, variable sediment types, and gas hydrates exposed on the seafloor. The expression of these features on the seafloor suggests a tectonically active area. The distribution of these different processes and their relation to the subsurface stratigraphy and tectonic setting are not well understood, yet an understanding of these issues is essential as exploration extends into this deep-water area.
To address the questions of surficial processes and their connection with deeper structures underlying this continental margin, a three-week cruise was conducted by the USGS in April, 1997 aboard the RV GYRE. The study area focussed on Bryant Canyon, a former submarine canyon, through which turbidity currents transported sands from a shelf-edge delta upslope of the study area to the Bryant Fan on the rise seaward of the base of the slope. The cruise was divided into two parts. The first part was devoted to collecting seismic-reflection profiles across parts of the canyon system to define the shallow stratigraphy and to determine the presence and distribution of gas hydrates in this area. Approximately 555 km of single-channel seismic-reflection data were collected during this first part of the cruise. A track map showing the locations of the profiles, low-resolution images of the profiles, and the SEG-Y format of these data are all presented on this CD-ROM. During the second part of the cruise, 38 piston cores were collected to describe the shallow subsurface facies of the study area. The coring data will be availible in an open file report to be published by Hans Nelson.

This report is the compilation for such features in the\r\nCentral and Eastern United States (CEUS), which for the purposes of the compilation, is\r\ndefined as the region extending from the Rocky Mountain Front eastward to the Atlantic\r\nseaboard. A key objective of this national compilation is to provide a comprehensive database\r\nof Quaternary features that might generate strong ground motion and therefore, should be considered\r\nin assessing the seismic hazard throughout the country. In addition to printed versions\r\nof regional and individual state compilations, the database will be available on the World-Wide\r\nWeb, where it will be readily available to everyone. The primary purpose of these compilations\r\nand the derivative database is to provide a comprehensive, uniform source of geological information\r\nthat can by used to complement the other types of data that are used in seismic-hazard\r\nassessments.\r\nWithin our CEUS study area, which encompasses more than 60 percent of the continuous U.S.,\r\nwe summarize the geological information on 69 features that are categorized into four classes\r\n(Class A, B, C, and D) based on what is known about the feature's Quaternary activity. The\r\nCEUS contains only 13 features of tectonic origin for which there is convincing evidence of\r\nQuaternary activity (Class A features). Of the remaining 56 features, 11 require further study in\r\norder to confidently define their potential as possible sources of earthquake-induced ground\r\nmotion (Class B), whereas the remaining features either lack convincing geologic evidence of\r\nQuaternary tectonic faulting or have been studied carefully enough to determine that they do not\r\npose a significant seismic hazard (Classes C and D).\r\nThe correlation between historical seismicity and Quaternary faults and liquefaction features\r\nin the CEUS is generally poor, which probably reflects the long return times between successive\r\nmovements on individual structures. Some Quaternary faults and liquefaction features\r\nare located in aseismic areas or where historical seismicity is sparse. These relations indicate\r\nthat the record of historical seismicity does not identify all potential seismic sources in the\r\nCEUS. Furthermore, geological studies of some currently aseismic faults have shown that the\r\nfaults have generated strong earthquakes in the geologically recent past. Thus, the combination\r\nof geological information and seismological data can provide better insight into potential\r\nearthquake sources and thereby, contribute to better, more comprehensive seismic-hazard\r\nassessments.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey,","doi":"10.3133/ofr00260","issn":"0094-9140","usgsCitation":"Crone, A.J., and Wheeler, R.L., 2000, Data for Quaternary faults, liquefaction features, and possible tectonic features in the Central and Eastern United States, east of the Rocky Mountain Front: U.S. Geological Survey Open-File Report 2000-260, 342 p., https://doi.org/10.3133/ofr00260.","productDescription":"342 p.","costCenters":[],"links":[{"id":155689,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":1541,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/ofr-00-0260/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac9e4b07f02db67c98f","contributors":{"authors":[{"text":"Crone, Anthony J. 0000-0002-3006-406X crone@usgs.gov","orcid":"https://orcid.org/0000-0002-3006-406X","contributorId":790,"corporation":false,"usgs":true,"family":"Crone","given":"Anthony","email":"crone@usgs.gov","middleInitial":"J.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":188895,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wheeler, Russell L. wheeler@usgs.gov","contributorId":858,"corporation":false,"usgs":true,"family":"Wheeler","given":"Russell","email":"wheeler@usgs.gov","middleInitial":"L.","affiliations":[],"preferred":false,"id":188896,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":23677,"text":"ofr0079 - 2000 - Hydrologic and water-quality data for ground water along the Milk River Valley, north-central to northeastern Montana","interactions":[],"lastModifiedDate":"2012-02-02T00:08:18","indexId":"ofr0079","displayToPublicDate":"2000-06-01T00:00:00","publicationYear":"2000","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2000-79","title":"Hydrologic and water-quality data for ground water along the Milk River Valley, north-central to northeastern Montana","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/ofr0079","issn":"0094-9140","usgsCitation":"Lawlor, S.M., 2000, Hydrologic and water-quality data for ground water along the Milk River Valley, north-central to northeastern Montana: U.S. Geological Survey Open-File Report 2000-79, iv, 24 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr0079.","productDescription":"iv, 24 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":157474,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0079/report-thumb.jpg"},{"id":19477,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2000/0079/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":52933,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0079/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a29e4b07f02db61173f","contributors":{"authors":[{"text":"Lawlor, Sean M. 0000-0001-5988-7548 slawlor@usgs.gov","orcid":"https://orcid.org/0000-0001-5988-7548","contributorId":1895,"corporation":false,"usgs":true,"family":"Lawlor","given":"Sean","email":"slawlor@usgs.gov","middleInitial":"M.","affiliations":[{"id":685,"text":"Wyoming-Montana Water Science Center","active":false,"usgs":true}],"preferred":true,"id":190531,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":32274,"text":"ofr99504 - 2000 - Landslides in Alameda County, California: A digital database extracted from preliminary photointerpretation maps of surficial deposits by T.H.
