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. Purpose: 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.

Data for surficial and materials point, line, and polygon coverages were determined in the field using 1:63,360-scale topographic maps and 1:50,000 (nominal) scale, color-infrared aerial photographs. Geologic data included in the compilation are the field maps and notes from this project as well as data from other sources as noted in the "Sources Cited" section. Attributes were verified for consistency and completeness during the creation of the metadata. Logical_Consistency_Report: Topology is present on appropriate polygon and line coverages; others are point coverages. Completeness_Report: This dataset includes coverages that contain information about geologic units, their ages, and field sample locations; and locations of terrace risers at 1:63,360 scale Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: DGGS location data and estimated position errors were manually entered into a spreadsheet. 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. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 100 Horizontal_Positional_Accuracy_Explanation: 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. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 110 Horizontal_Positional_Accuracy_Explanation: A value of estimated position error in meters. Surficial 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 surficial 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 surficial geologic map features is estimated to be approximately 110 meters.

See this publication cited in the Process Step section below. Process_Step: Process_Description: Fieldwork - Fieldwork for surficial 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.

Process_Date: 1999 Process_Step: Process_Description: Photo interpretation - Before, during, and after field work, surficial-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.

Surficial-geologic polygons and lines were then edited and attributed using Arc, Info, and ArcEdit. Bedrock point data of locations of structural observations (strike, dip, cleavage, jointing, etc.) were intersected with the surficial-geologic polygon coverage using the Arc command "intersect" in order to identify locations that were mapped as surficial materials based on aerial photography but were found to have small exposures that were desirable to be mapped as bedrock. These areas were then modified in the surficial-geologic coverages to be areas of bedrock exposure. Final bedrock and surficial geology polygon coverages were merged using the Arc command "union" to generate the polygon coverage used to make the comprehensive geologic map. Other cartographic elements, primarily text and tables, were created in CorelDraw, converted to CGM format, and imported into ArcPlot for final layout.
