Data

In 2016, with National Park Service support, several previously undated plutons were sampled in Glacier Bay National Park and Preserve along the west side of Glacier Bay for age determinations. Geochronologic analyses were conducted to determine the ages of the plutonic rocks in the Glacier Bay area. Five samples were collected by Frederic Wilson (USGS Alaska Science Center), from Dundas Bay and G

This data set provides low-temperature thermochronometric data from 16 rock samples collected from the Revelation Mountains area in western Alaska Range. These data are from three different analyses used to estimate cooling ages: 1) apatite (U-Th)/He, 2) zircon (U-Th)/He, and 3) apatite fission-track.

This data set contains 3 tables containing uranium-lead (U-Pb) isotopic data and crystallization ages of zircon and titanite from igneous, metamorphic, and sedimentary rocks collected from the Yukon-Tanana upland of eastern interior Alaska between 2013 and 2019. Bulk samples of igneous and metamorphic rocks were processed into concentrated mineral separates of zircon and (or) titanite in USGS labo

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 20 satellite transmitters attached to Thick-billed murres on their breeding range in arctic and western Alaska, 1995-1996. Five data files are included in the "rawData" folder of this data package. Two data files (with identical co

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 28 satellite transmitters attached to Common murres on their breeding range in arctic and western Alaska, 1994-1996. Five data files are included in the "rawData" folder of this data package. Two data files (with identical content)

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 2 satellite transmitters attached to Red-faced cormorants on Attu Island Alaska, 2006. Five data files are included in the "rawData" folder of this data package. Two data files (with identical content) contain the raw Argos DIAG (D

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 8 satellite transmitters attached to Pelagic cormorants on Middleton and Attu Islands, Alaska, 2000-2006. Five data files are included in the "rawData" folder of this data package. Two data files (with identical content) contain th

This dataset presents boundaries and attributes of mapped geomorphic features in the lower 7.5 kilometers of the Taiya River valley bottom in and near Klondike Gold Rush National Historical Park near Skagway, Alaska. Geomorphic surfaces and off-main-stem channels were delineated from 2003 lidar elevation data and updated using 2017 and 2018 aerial orthophotographs at eroding riverbanks, such that

This dataset includes soil data collected from various landscapes adjacent to thaw ponds on the North Slope of Alaska between 2012 and 2018. The landscapes include ice-rich polygonal ground found on basin uplands, as well as bluffs and lake edges. At each site a visual description of soil type and texture was performed, and a permafrost probe was used to determine a 'depth to refusal'. Given that

This dataset includes physical, hydraulic, and thermal properties of soils collected in two sub-watersheds in the Noatak River Basin in northwestern Alaska. Physical properties include dry bulk density and porosity. Hydraulic properties include field- and lab-based hydraulic conductivity, soil-water retention data, and parameters used in a common soil-water retention model (van Genuchten model). T

This data set includes 15-minute interval data on stream temperature, stage, and discharge from low-order streams in the Yukon River Basin in interior Alaska, collected during the summer months. The depth of the water and temperature were determined using a combined pressure transducer and temperature sensor that was deployed through the summer months. Different sensors were used in each stream an

This data set documents the width of annual otolith growth increments from Lake Trout collected in lakes within Lake Clark National Park and Preserve, Alaska. The analysis of this data was published in von Biela et al. 2020 (DOI: 10.1111/eff.12566)
