Major-oxide, minor-oxide, and trace-element geochemical data from rocks collected in 2008 in the eastern Bonnifield mining district, Fairbanks and Healy quadrangles, Alaska

Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys carried out a geological field survey, including mapping and sampling, in the eastern part of the Bonnifield mining district in the Fairbanks A-1 and A-2, and the Healy D-1 and D-2 quadrangles, Alaska, from June 16 through July 18, 2008. The fieldwork provides basic information critical to building an understanding of Alaska's geology and is part of an integrated program of airborne geophysical surveys followed by geological mapping. Specifically, this work provides geologic context for geophysical surveys conducted in 2006. To represent a typical lithology, igneous or possible meta-igneous samples were collected and analyzed for major- and minor-oxide and petrogenetically important trace elements as a supplement to previously published geochemical data. The analyses were used to determine composition of the samples as well as potential original tectonic setting. Radiometric age analyses from some of these rocks have been published. Interpretation and synthesis of this data has been presented in professional and trade meetings. The analytical tables associated with this data release are available in digital format as comma-separated value (CSV) files.

Shoreline change at Alaska coastal communities, Naknek, 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, Tanana 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 highest-hit digital surface models (DSM) represent the earth's surface with all vegetation and human-made structures included.

Geologic map of the Big Delta A-4 Quadrangle, Alaska

This map illustrates extents and types of unconsolidated deposits and bedrock in the Big Delta A-4 Quadrangle, Alaska. This map is based on field observations begun by P�w� in 1949 and by Reger in 1976. Unit characteristics and extents were determined during field visits and by interpreting 1:40,000-scale black-and-white aerial photographs taken in August 1949 and 1:63,360-scale, false-color infrared aerial photographs taken in July 1978, August 1980, and August 1981.

Geochemistry of some quaternary lavas from the Aleutian Arc and Mt. Wrangell

This publication contains previously unpublished geochemical analyses or re-analyses of lavas, magmatic inclusions, and a few gabbroic cumulate inclusions from Alaska volcanoes (Akutan, Augustine, Buzzard Creek, Dana, Douglas, Fourpeaked, Frosty, Great Sitkin, Iliamna, Kaguyak, Kiska, Okmok, Prindle Cone, Recheshnoi, Redoubt, Spurr, Ukinrek Maars, Vsevidof, Westdahl, Wrangell) collected by the authors and others over the past 35 years. It provides substantial data sets for three volcanoes (Vsevidof, Westdahl, and Douglas) for which little or no published data exist. All analyses were made by the GeoAnalytical laboratory at Washington State University in Pullman, WA. The ICP/MS data have been reduced using the 2006 calibration to ensure internal consistency of the data set despite the twenty-year span over which the analyses were made. Files can be downloaded from the DGGS website (http://doi.org/10.14509/29843).

Tsunami inundation maps for Skagway and Haines, Alaska

In this report we evaluate potential tsunami hazards for the southeastern Alaska communities of Skagway and Haines and numerically model the extent of inundation from tsunami waves generated by tectonic and submarine landslide sources. We calibrate our tsunami model by numerically simulating the 2011 Tohoku, Japan tsunami at Skagway and comparing our results to instrument records. Analysis of calculated and observed water level dynamics for the 2011 event in Skagway reveals that the model underestimates the observed wave heights in the city by a factor of 1.5, likely due to complex tsunami-tide interactions. We compensate for this underestimation numerically by increasing the coseismic slip of the hypothetical tsunami sources in our models. Potential hypothetical maximum credible tsunami sources include variations of the extended 1964 rupture and megathrust earthquakes in the Prince William Sound and Alaska Peninsula regions. Local underwater landslide events in Taiya, Chilkoot, and Chilkat inlets are also considered as possible tsunamigenic scenarios. The results show that the maximum predicted wave height resulting from a tectonic tsunami is 2-3 m (7-10 ft) in Skagway and Haines, while the maximum landslide-generated tsunami may cause a runup of 15-16 m (49-52 ft). Results presented here are intended to provide guidance to local emergency management agencies in tsunami inundation assessment, evacuation planning, and public education to mitigate future tsunami hazards. Users can access the complete report and digital data from the DGGS website: http://doi.org/10.14509/30029.

Hetta electromagnetic and magnetic airborne geophysical survey data compilation

The Hetta geophysical survey is located in southeast Alaska in the Ketchikan area, about 350 kilometers south of Juneau, Alaska. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system in May 1992. A total of 1,707 line kilometers were collected covering 323.3 square kilometers. Line spacing was 200 meters (m). Data were collected approximately 30 m above the ground cover or tree canopy from a helicopter-towed sensor platform ("bird") on a 30-m-long line. The large trees and steep terrain resulted in an average ground clearance of 150 m. The Hetta survey was flown for the American Copper & Nickel Company, Inc. and provided to DGGS by the Sealaska Corporation. The data were merged and released with the 1999 Ketchikan geophysical survey maps. Map sheets and some of the other files in this data release contain data from adjacent or nearby surveys. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30433.
