High-resolution lidar data for infrastructure corridors, Beechey Point 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.

Preliminary bedrock geologic map data for the eastern Bonnifield mining district, Fairbanks and Healy quadrangles, Alaska

Mineral Resources Section personnel from the Alaska Division of Geological & Geophysical Surveys (DGGS) carried out a geologic 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 geologic mapping. Specifically, this work provides geologic context for geophysical surveys conducted in 2006. Interpretation and synthesis of this data has been presented in professional and trade meetings. This report and associated geologic map data are preliminary, have not undergone rigorous peer review, and will be superseded by a subsequent Report of Investigations map and report that will be issued later in 2016. The objective of the eastern Bonnifield project is to produce a 1:50,000-scale geologic map to foster a better understanding of the area's geology and mineral potential. Although DGGS concentrated on mapping the Paleozoic metamorphic rocks that host the volcanogenic massive sulfide deposits (VMS) and Mesozoic igneous rocks associated with Au-Ag-As-Sb veins, we also studied the Tertiary sedimentary section, which could contain coal resources. The geologic map data are available in digital format as ESRI shapefiles.

Fortymile mining district electromagnetic and magnetic airborne geophysical survey, data compilation

The Fortymile electromagnetic and magnetic airborne geophysical survey data were acquired with a DIGHEM-V Electromagnetic (EM) system and a cesium magnetometer. The EM and magnetic sensors were flown at a height of 30 meters (m). In addition the survey recorded data from radar and laser altimeters, a GPS navigation system, 50/60 Hz monitors and a video camera. Flights were performed with an AS-350-B2 Squirrel helicopter at a mean terrain clearance of 60 m along N-S survey flight lines with a spacing of 400 m. Tie lines were flown perpendicular to the flight lines at intervals of approximately 4,800 m

Regional tsunami hazard assessment for the communities of Kasaan, Klawock, Metlakatla, Pelican, Point Baker, and Port Protection in Southeast Alaska

We assess potential tsunami hazards for six communities in Southeast Alaska: Kasaan, Klawock, Metlakatla, Pelican, Point Baker, and Port Protection. These communities have no high-resolution bathymetry or topography; therefore we conduct tsunami hazard assessments for these areas at the regional scale. The regional approach is a suitable, cost- effective approximation and replacement for high-resolution tsunami inundation maps. The primary tsunami hazard considered for these communities originates from tsunamigenic earthquakes along the Alaska-Aleutian subduction zone across the Gulf of Alaska. We numerically model tsunami waves generated by four different megathrust earthquakes and develop approximate tsunami hazard maps for the six communities. The hypothetical tsunami scenarios that we examined include variations of an extended 1964 rupture, megathrust earthquakes in the Prince William Sound and Alaska Peninsula regions, and a Cascadia megathrust earthquake. We do not include impacts of subaerial or submarine landslide tsunami sources, as that is beyond the scope of this study. The maximum runup heights from tectonically-generated tsunamis are 1.4 m (4.6 ft) in Kasaan, 4 m (13 ft) in Klawock, 1 m (3.3 ft) in Metlakatla, 5 m (16 ft) in Pelican, 1.3 m (4.3 ft) in Point Baker, and 2.6 m (8.5 ft) in Port Protection. Results presented here are intended to provide guidance to local emergency management agencies in initial tsunami inundation assessment, evacuation planning, and public education for mitigation of future tsunami hazards. The complete report and digital data are available from the DGGS website: http://doi.org/10.14509/30423.

Photogrammetric digital surface models and orthoimagery for the continuous coastline, Wales to Platinum, Alaska, segment K: Nightmute to Kipnuk

Aerial photographs of the coastline from Nightmute to Kipnuk were collected on August 11, 2015 and September 9, 2015. The photographs were processed using Structure-from-Motion (SfM) photogrammetric techniques. Global Positioning System (GPS) checkpoints were collected via a Global Navigation Satellite System (GNSS) survey conducted between August 15 and September 14, 2015. For the purposes of open access to elevation and orthoimagery datasets in coastal regions of Alaska, this collection is being released as a Raw Data File with an open end-user license. Orthoimages contain 4-band, 8-bit, unsigned raster data (red/green/blue/no data; file format-GeoTIFF; source-Fairbanks Fodar) with 20 cm GSD. No-data values are found in band 4 or shown as transparent in red/green/blue images. The file employs Lempel-Ziv-Welch (LZW) compression. Light exposures in the orthoimages are a result of daily weather conditions, which ranged from low cloud cover, rain, and full sun.

Jarvis Creek coal report

In July and August of 2016, the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted a field study in the Jarvis Creek coal field to better characterize these coal deposits. The Jarvis Creek Coal field is located on the north side of the Alaska Range in the Mt. Hayes C-4 quadrangle. It represents the eastern-most coal field in the east-west trending Nenana Coal Province. Located approximately 10 miles southeast of Donnelly Dome, it is bounded on the west by the Delta River, on the east by Jarvis Creek and on the south by Ruby Creek. The field is three to six miles east of the Richardson Highway and is approximately 16 square miles in area. Coal-bearing outcrops of the lower, middle, and upper units were examined in three locations in the Jarvis Creek coalfield. These locations include: 1) north of Ruby Creek, 2) the end of Coal Mine Road near the old Ober Creek mine site, and 3) near Sargent Creek in the northern part of the field. All coal samples were collected as channel samples. Eighteen samples were collected from six stations. This Preliminary Interpretive Report presents results from coal quality (proximate and ultimate analysis), Rock-Eval, hydrous pyrolysis, vitrinite reflectance, and kerogen microscopy analyses. Users can access the complete report and digital data from the DGGS website: http://doi.org/10.14509/30064.

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.
