Major-oxide, minor-oxide, and trace-element geochemical data from rocks and stream sediments collected in the northern Fairbanks mining district, Circle quadrangle, Alaska in 2007

Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys carried out a geological field survey, including mapping and sampling northeast of Fairbanks in the Circle A-4, A-5, B-4, and B-5 quadrangles, Alaska from May 31 to June 28, 2007. The fieldwork provides basic information critical to building an understanding of Alaska geology and is part of an integrated program of airborne geophysical surveys followed by geological mapping. During 2007, 128 rock samples were collected for geochemical trace-element analysis, and 44 rock samples were collected for whole rock (major- and minor-oxide) analysis. Petrogenetically important trace-elements will be analyzed in a subsequent study to be published with the final map and report for this area. In addition, 67 stream sediment samples were collected for geochemical trace-element analysis. The stream sediment geochemical study was conducted over the proposed Mount Ryan Remote Recreational Cabin Staking Area as considered by Alaska's Division of Mining, Land & Water in 2007.

Shoreline change at Alaska coastal communities, Nunam Iqua, Alaska

The Division of Geological & Geophysical Surveys has analyzed long-term shoreline change at 48 Alaska communities. Shoreline datasets were compiled from previously published U.S. Geological Survey assessments and created from historical and recent aerial images by the Alaska Division of Geological & Geophysical Surveys. Shorelines were analyzed to calculate shoreline change rates every 25 meters along coastlines and tidally influenced riverbanks using the Digital Shoreline Analysis System (DSAS; Himmelstoss and others, 2018). The geodatabase for each community includes shoreline positions, the alongshore baseline used to cast transects, and transects that include shoreline change rates and statistics. All files can be downloaded free of charge from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30552).

High-resolution lidar data for infrastructure corridors, Chandalar Quadrangle, Alaska

In advance of design, permitting, and construction of a pipeline to deliver North Slope natural gas to out-of-state customers and Alaska communities, the Division of Geological & Geophysical Surveys (DGGS) has acquired lidar (Light Detection and Ranging) data along proposed pipeline routes, nearby areas of infrastructure, and regions where significant geologic hazards have been identified. Lidar data will serve multiple purposes, but have primarily been collected to (1) evaluate active faulting, slope instability, thaw settlement, erosion, and other engineering constraints along proposed pipeline routes, and (2) provide a base layer for the state-federal GIS database that will be used to evaluate permit applications and construction plans. The normalized digital surface models (nDSM) represent the above ground elevation of the highest laser return with all vegetation included.

W00333: NOS Hydrographic Survey , 2014-07-20

The National Oceanic and Atmospheric Administration (NOAA) has the statutory mandate to collect hydrographic data in support of nautical chart compilation for safe navigation and to provide background data for engineers, scientific, and other commercial and industrial activities. Hydrographic survey data primarily consist of water depths, but may also include features (e.g. rocks, wrecks), navigation aids, shoreline identification, and bottom type information.

Single-beam bathymetry data collected in shallow-water areas near Gambell, Golovin, Hooper Bay, Savoonga, Shishmaref, and Wales, Alaska, 2012-2013

Nearshore bathymetry is a vital link that joins offshore water depths to coastal topography. Seamless water depth information is a critical input parameter for reliable storm surge models, enables the calculation of sediment budgets, and is necessary baseline data for a range of coastal development decisions. Bathymetric data collection capabilities of an active coastal geohazard field program operated by the Alaska Division of Geological & Geophysical Surveys (DGGS) were expanded in 2012. Resultant datasets presented in this report include nearshore bathymetric measurements of critical shallow-water coastal areas in the vicinity of six western Alaska communities: Gambell, Golovin, Hooper Bay, Savoonga, Shishmaref, and Wales. These data are provided in the form of vector shiptracks and processed single-beam sounding point clouds. This work was completed with a low-cost, portable sonar system capable of shallow water measurements in rural settings; the system will be maintained for use or loan by DGGS for data collections of this type for the useful life of the equipment.

Bedrock geologic map of the Eagle A-1 Quadrangle, Fortymile mining district

Geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted field investigations and geochemical rock sampling during the 1999, 2000, and 2001 field seasons to produce a 1:63,360 scale bedrock map of the Eagle A-1 Quadrangle, Alaska. Rock outcrop throughout the field area is limited; consequently, the map interpretation relies heavily on airborne magnetic and electromagnetic survey data and accompanying geochemical analysis of rock samples. Field investigations are part of a three-year mapping program to provide geologic ground truth for airborne geophysical surveys flown by DGGS in the Fortymile mining district during 1998. This work aims to build an improved understanding of the area's geology and controls on gold mineralization for purposes of exploration targeting and mineral-resource assessment. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/2864.

Liscum electromagnetic and magnetic airborne geophysical survey data compilation

The Liscum electromagnetic and magnetic airborne geophysical survey is located in interior Alaska in the Goodpaster mining district, about 120 kilometers southeast of Fairbanks, Alaska. The survey is adjacent to the Goodpaster geophysical survey. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from September to November 2005. A total of 621.4 line kilometers were collected covering 181.6 square kilometers. Line spacing in the eastern block of the survey was 400 meters (m) and line spacing in the western block of the survey was 300 m. Data were collected 30 m above the ground surface from a helicopter towed sensor platform ('bird') on a 30 m long line. The survey was conducted by Fugro Airborne Surveys Corp. and Stevens Exploration Management Corp. and administered by the Alaska Geological & Geophysical Surveys (DGGS). The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/29755.

Core fragment descriptions, Exxon core holes, uplands bordering Yukon Flats basin, east-central Alaska

This Raw Data File provides lithologic descriptions of core fragments recovered from a series of core holes drilled by Exxon (mid-80s) in the uplands bordering the Yukon Flats basin. In addition to descriptions of the material, the tabulated file includes geographic location, core hole numbers, an age estimate, core fragment depth, general lithology, grain size, and facies interpretation. The author examined these core materials in Fairbanks during winter and spring 2002. This work was done in preparation for an assessment carried out by the U.S. Geological Survey of undiscovered, technically recoverable hydrocarbon resources in the Yukon Flats basin.
