Whole rock, soil, sediment, x-ray diffraction, and electron microprobe analyses of samples from the Orange Hill-Bond Creek area, Nabesna Quadrangle, Alaska This data release includes geochemical, x-ray diffraction mineralogical, and electron probe microanalysis (EPMA) data on rocks, soils, and sediments collected near the Orange Hill and Bond Creek porphyry copper deposits, Nabesna quadrangle, Alaska. Geochemical analyses were completed by a laboratory under contract with the U.S. Geological Survey (USGS). Electron microprobe and x-ray diffraction mineralogical analyses were completed by personnel of the Central Region Minerals Program in Denver, Colorado. The samples were collected and analyzed during 2014 to 2016, selected to help characterize the distribution and composition of mineralized and unmineralized geologic materials in this remote part of the eastern Alaska...

DENA preserves over 6 million acres of wild land that provides opportunities for recreation, subsistence hunting and gathering, preservation of cultural resources, and scientific research. Despite its size and popularity, DENA has only one road—the dead-end, 92-mile Denali National Park Road (hereafter referred to as the Park Road). The Park Road is mostly gravel; only the first 15 miles are paved. It is the only access for most DENA infrastructure, including visitor centers, staff facilities, campgrounds, and businesses. The Park... Categories: Data; Types: Downloadable, Map Service, OGC WFS Layer, OGC WMS Layer, Shapefile; Tags: Alaska, Alaska Range, Browne glaciation, Cantwell Basin, Cantwell Formation, All tags...

This area contains exposed porphyry deposits and hand samples were collected throughout the region in support of the HyMap imaging spectrometer survey (https://doi.org/10.5066/F7DN435W) (Kokaly and others, 2017a). The HCI-III system consists of three different components. The first is an imaging spectrometer which collects reflectance data with a spatial resolution of approximately 500 nanometers (nm) for 514 spectral channels covering...

Ecoregions are defined by climate, terrain, vegetation, and soils; their utility in explaining distributions of aquatic organisms is based upon terrestrial-aquatic linkages. Analysis of the probable dispersal of aquatic organisms along past and current hydroregions provides an alternative and likely complementary path to understanding distributions of aquatic organisms. We use published distribution records for freshwater fishes of Alaska to construct a matrix of presence/absence records for each fish species in ecoregions and hydroregions of Alaska. We assessed faunal similarities among...

Like the Alaska Geochemical Database Version 2.0 before it, the AGDB3 was created and designed to compile and integrate geochemical data from Alaska to facilitate geologic mapping, petrologic studies, mineral resource assessments, definition of geochemical baseline values and statistics, element concentrations and associations, environmental impact assessments, and studies in public health associated with geology.
