This mapping project reinterprets micropaleontologic correlations for 17 Sagavanirktok Quadrangle wells, and reprocesses data from the one publicly-available seismic line. Surface geologic mapping, subsurface-to-surface stratigraphic age control, and seismic framework are required to reliably decipher the complex geology of this key area of the Brooks Range. Outcrops within the Sagavanirktok B-1 Quadrangle are the closest surface expressions of Prudhoe Bay source and reservoir rocks. This study yields critical petroleum-related information from these surface exposures, and how they relate to the area subsurface stratigraphy. At the time this project was published, the State of Alaska depended on the petroleum industry for approximately 80 percent of its revenue, most of which comes from oil fields on the North Slope. North Slope oil production is declining. This mapping project addresses this problem by providing the state and industry with the first published geologic map of this part of the North Slope oil province at a scale other than 1:2,500,000. Detailed geologic mapping of the quadrangle addresses the lack of understanding of the petroleum-geology framework of the eastern North Slope, Colville basin, and the stratigraphic transition from the National Petroleum Reserve in Alaska (NPRA) to the Arctic National Wildlife Refuge (ANWR). This detailed mapping and petroleum-related data is pertinent to oil exploration for Prudhoe Bay satellite fields and new play-type reevaluations, as well as assist private-sector exploration efforts, and speed the exploration process. This data will contribute to increased confidence in exploration and evaluation efforts in areas west of Prudhoe Bay. Funding for the geologic mapping was provided by the U.S. Geological Survey, National Cooperative Geologic Mapping Program, under STATEMAP award number 99HQAG0121 under the NCGM STATEMAP program for FY1999.

Sample numbers and locations with selected data were spatially registered and analyzed in ArcGIS software. Location data for the surficial and materials maps were determined visually using topographic maps at a scale of 1:63,360 and 1:50,000 (nominal) scale, color-infrared aerial photographs. See "Source_Information" section for horizontal positional accuracy of locations not measured by DGGS. Horizontal Positional Accuracy A value of estimated position error in meters was calculated by the GPS units and recorded for each sample location. This error results from items such as error in satellite positions, mathematical error introduced by the formulas used by the GPS unit for calculating position, and errors caused by narrow satellite alignments. Estimated position error is a value determined by the GPS manufacturer for the calculation and geometric error as a whole. "Selective availability," a deliberate degradation of GPS data managed by the U.S. government that induces an additional error of approximately 100 meters to a GPS location, was in effect until May 1, 2000, and thus during the time of this field work. meters 100 Horizontal Positional Accuracy A value of estimated position error in meters. Engineering geologic map data have a horizontal positional accuracy dependent on: 1) the 1:50,000-scale (nominal) aerial photographs on which it is based, with an estimated potential error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; 2) the accuracy of the human zoom transfer scope operator in tracing the line work from acetate overlays to topographic base maps, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; 3) the accuracy of the zoom transfer process itself, error magnitude highly variable and unknown but potentially large; 4) the digitizing RMS error of 0.003 inches (input coverage units), which equates to approximately 5 meters on the ground for a 1:63,360-scale map; and 5) the accuracy of the human operator digitizing the geologic from the topographic base maps, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground. The engineering geologic field maps were digitized using a map tablet and cross-hair mouse. Map error is induced by: (1) transferring map data from base topography to a mylar compilation map, with an estimated potential error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; (2) the digitizing RMS error [24 control points on a regular grid have an average RMS error of 10.8 meters on the ground; individual control point error ranges from 4.3 to 21.2 meters on the ground]; and (3) the accuracy of the human operator digitizing the geologic line work from the topographic base map, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground. Total potential horizontal error for engineering geologic map features is estimated to be approximately 110 meters. meters 110 This dataset includes coverages that contain information about engineering-geologic units, and field sample locations at 1:63,360 scale. This dataset includes coverages that contain information about engineering-geologic units, and field sample locations at 1:63,360 scale. Topology is present on appropriate polygon and line coverages; others are point coverages. This lineage was generated by the FGDC CSDGM to 19139 transformation Fieldwork - Fieldwork for surficial/engineering geologic investigations, including ridge and valley traverses, road cut investigations, and river exposures, was conducted for approximately 5 person-days during June 21-25, 1999 by a surficial geologist. Field notes and sediment samples were collected throughout the area for surficial investigations. Surficial mapping involved using sources cited below on a regular basis for checking and correlating general units. The surficial mapper recorded observations on co-registered acetate overlays on 1:50,000-scale (nominal) color-infrared aerial photographs (Alaska High Altitude Aerial Photography, 1978, 1982), and directly on 1:63,360-scale topographic base maps. Stations were located using air photos and topographic maps. 1999-01-01T00:00:00 Laboratory data - See the report RI 2000-1D for more information. 1999-01-01T00:00:00 Photo interpretation - Before, during, and after field work, surficial/engineering geologic information was interpreted using 1:50,000-scale (nominal) color-infrared air-photo stereopairs, and compiled onto acetate overlays. Photo interpretation was based on field notes from fieldwork process step (above), observed land forms and relationships in the photos, and all known geologic data from previous work in the area. The main sources of existing data include the references listed below. The overlay information was transferred to a paper 1:63,360-scale USGS topographic base using a zoom transfer scope. 1999-01-01T00:00:00 Digital Cartography - Surficial/engineering geologic information was digitized from the paper USGS topographic base map into Arc/Info 7.0.4 GIS (ArcEdit module) using a large-format digitizing table. Surficial/engineering geologic polygons and lines were then edited and attributed using Arc, Info, and ArcEdit. Other cartographic elements, primarily text and tables, were created in CorelDraw, converted to CGM format, and imported into ArcPlot for final layout. Data from the comprehensive geologic map of the area were used as the basis for generating the derivative engineering-geologic map. An ArcInfo lookup table was made to assign geologic units (item UNIT) from the comprehensive map to appropriate engineering-geologic units (item MAT) based on the Unified Soil Classification System as described by Wagner (1957). This lookup table was applied to the ArcInfo polygon coverage containing the geologic units and a new engineering-geologic polygon coverage was generated using the "dissolve" command based on the new materials-unit item "MAT." Additional features were mapped from ground observations and interpretation of air photos, and digitized and attributed using ArcInfo. ArcPlot was used to generate plot files of the resulting materials coverage using DGGS-standard symbology. 2000-01-01T00:00:00 Source Contribution: These data were used to further define the geology of the Sagavanirktok B-1 area.
