High-resolution lidar data for infrastructure corridors, Anchorage 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. Bare-earth digital elevation models (DEM) represent the earth's surface with all vegetation and human-made structures removed.

Koyukuk electromagnetic and magnetic airborne geophysical survey data compilation

The Koyukuk geophysical survey is located in interior Alaska in the Koyukuk mining district, about 300 kilometers north of Fairbanks, Alaska. Frequency domain electromagnetic and magnetic data were collected with the SIGHEM-5 system from August to October 1997. A total of 4223.4 line kilometers were collected covering 533 square kilometers. Line spacing was 400 meters (m). Data were collected 30 m above the ground surface from a helicopter towed sensor platform ("bird") on a 30-m-long line. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30434.

Ground gravity geophysical survey of the Holitna basin area, Alaska, data compilation

Gravity data were acquired at 1,175 stations during the period April 13 to May 3, 1982 by EDCON, Inc. using a helicopter-borne inertial surveying system and LaCoste and Romberg G-meters. Of the total number of stations, 1,156 were acquired along one of 19 lines and the remaining 19 stations were control points or gravity bases. The survey is located in southwestern Alaska approximately 325 kilometers west of Anchorage, Alaska. Stations acquired along the 19 lines. In general, gravity stations were spaced approximately 1,600 meters apart along northwest-southeast oriented lines which were spaced 9,500 meters apart. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30461.

Alaska shoreline change tool

Coastlines are dynamic features that change shape and position on a range of timescales. As a result of this variability, many coastal communities in Alaska must carefully consider patterns of coastal erosion and/or accretion to appropriately plan for the future. Until now, a lack of available information and resources related to shoreline positional data has created challenges in assessing and planning for coastal hazards such as erosion. To address this identified data need, the Alaska Division of Geological & Geophysical Surveys (DGGS) has created the Alaska Shoreline Change Tool, an interactive map that displays historical and projected shoreline positions. This new tool will improve hazard assessments and aid in local management decisions. The Alaska Shoreline Change Tool contains the best available information for shoreline change analysis in Alaska. These data come from many sources and include contributions from shoreline mapping projects conducted by numerous investigators. This digital data distribution package provides digitized, historic shorelines that are proximal to the community of Wales.

Geologic map of the Kavik River area, northeastern Brooks Range, Alaska

Report of Investigation 2011-3A, Geologic map of the Kavik River area, northeastern Brooks Range, Alaska, presents 1:63,360-scale geologic mapping of the Mt. Michelson B-5 and C-5 quadrangles and the western portion of the B-4 and C-4 quadrangles. The Kavik River region is one of the few areas that permit examination of all three depositional megasequences of northern Alaska in close association. Several occurrences of oil-stained sandstone have been noted in outcrop and the undeveloped Kavik field that lies in the north-central part of the map is estimated to contain 165 billion standard cubic feet of natural gas. In concert with geologic mapping, stratigraphic units significant for oil and gas exploration were examined in detail, including acquisition of a number of measured sections. Local analysis of the sedimentology and stratigraphy focused particularly on the more prospective Beaufortian and Brookian units. The dataset contains geologic, structural, stratigraphic, and geochronologic data organized according to the GeMS and AK GeMS mapping schemas. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/22602.

Geospatial distribution of tephra fall in Alaska: a geodatabase compilation of published tephra fall occurrences from the Pleistocene to the present

Tephra fall (volcanic ash) studies are a key component to understanding the frequency and magnitude of volcanic eruptions and conducting volcano-hazard assessments. In addition, many interdisciplinary studies rely on tephra fall deposits as time-stratigraphic markers. Information on tephra deposits in Alaska has previously been dispersed amongst hundreds of publications that span numerous research disciplines. In order to streamline tephra occurrence data, information from these disparate publications have been compiled into one comprehensive geospatial dataset. Pleistocene, Holocene, and historical tephra deposit distribution information has been digitized for more than 120 published resources, including peer-reviewed articles, reports, and theses/dissertations. The dataset includes tephra fall distribution information pertaining to 39 eruptions from at least 19 volcanoes in Alaska. All files can be downloaded free of charge from the DGGS website (http://doi.org/10.14509/29847).

Analyses of historic U.S. Bureau of Mines samples for geochemical trace-element and rare-earth-element data from Kook Lake, Sitka Quadrangle, Alaska

This report and digital data release presents 26 new geochemical analyses on historic U.S. Bureau of Mines (USBM) samples, including 4 rock, 9 stream sediment, 3 soil, and 10 heavy mineral concentrate (pan concentrate) samples. These samples were originally collected by the USBM to investigate rare-earth-element occurrences associated with the Kook Lake intrusive complex, Sitka Quadrangle, Alaska. Historic USBM sample materials were retrieved by DGGS from the DGGS Geologic Materials Center (GMC), where the USBM samples were transferred as part of the federally funded Minerals Data and Information Rescue in Alaska (MDIRA) program in the late 1990s and early 2000s. The text and analytical data and tables associated with this report are being released in digital format as PDF files and .csv files. We provide analytical data, detection limits and, when available, the method documentation provided to us by the lab. We also provide the sample location in geographic coordinates, the sample material cited by the originating literature, a reference to the originating report, and the type of sample material that was obtained from the archive and sent to the lab.

Ground gravity measurements from Goldstream Valley, interior Alaska

The Goldstream Valley, located in Fairbanks, Alaska, is a semi-urban arctic watershed targeted for multidisciplinary investigations of interactions between permafrost, groundwater, surface hydrology, and biogeochemical cycles to understand the release of methane gas from degrading permafrost. To support concurrent research, Alaska Division of Geological & Geophysical Surveys (DGGS) staff collected gravity measurements from 105 stations throughout the Goldstream Valley during 2017 and 2018 (fig. 1). These stations were collected to help determine the depth of fill in the Goldstream Valley. Bouguer anomaly maps were created of the study area. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30473.
