Title:
2021 Arctic Strategic Transportation and Resources (ASTAR) project field geotechnical data and sample descriptions: Wainwright, Atqasuk, and Utqiagvik, North Slope, Alaska
Abstract:
2021 Arctic Strategic Transportation and Resources (ASTAR) project field geotechnical data and sample descriptions: Wainwright, Atqasuk, and Utqiagvik, North Slope, Alaska, Raw Data File 2023-5, presents sample locations and descriptions of 84 samples from power-auger holes, outcrops, test pits, and representative surface exposures from 2021 fieldwork in northwestern Alaska between Wainwright, Atqasuk, and Utqiagvik. This work supports sand and gravel resource assessment for the Arctic Strategic Transportation and Resources (ASTAR) Project.

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)
  2. Who also contributed to the data set?
    The State of Alaska funded this work as part of the ASTAR Capital Improvement Project. The U.S. Bureau of Land Management provided additional funding and support through a National Petroleum Reserve-Alaska Resource Inventory and Database Development Grant (L18AC00019-03). DGGS ASTAR work supports a collaborative effort between the North Slope Borough and the Department of Natural Resources to strengthen community infrastructure and facilitate access to arctic resources while enhancing the quality of life and economic opportunities for North Slope communities. It also provides valuable information for land-use management and planning decisions. We appreciate the collaboration and support of AKDOT&PF. In addition, the Alaska Energy Services Corporation (ASRC), North Slope Borough, Olgoonik Corporation, and City and Native Village of Wainwright provided much-appreciated logistical support and guidance during field preparation and data collection efforts which ensured a successful field season. We would also like to importantly thank Anthony T. Gallagher (DGGS), Hans A. Hoffman (ASRC), and Timothy G. Tannenbaum (AKDOT&PF) for crucial guidance before and during the summer season identifying areas of interest, conducting fieldwork, and collecting essential data, as well as Rainer J. Newberry for assisting with rock identification and geochemical analysis in the lab, and David A. Harvey for helping with revisions to the text.

Why was the data set created?

This study was implemented as part of the Arctic Strategic Transportation and Resource (ASTAR) project, which aims to evaluate sand and gravel resources along a corridor approximately between Nuiqsut, Atqasuk and Barrow, AK. The project will generate geologic maps and a database with information about location of geologic observations as well as the quality and types of geologic materials

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 2021 (process 1 of 3)
    Sample collection - Location data were collected using GPS-enabled tablets running the ESRI ArcGIS Collector app, which have a reported error of approximately 10 m. Latitude and longitude are reported in the WGS84 datum. Sediment samples were collected between July 6 and July 21, 2021. Sediment sample labels correspond to field station locations. Samples were collected from outcrops, the ground surface adjacent to streams and lakes, and 7-cm-diameter auger holes drilled to a depth of approximately 3.5 m. All samples were stored in resealable plastic bags. At some locations we collected a series of samples across a vertical exposure (profile description or auger) to determine changes in sediment character. Bulk composition samples were also collected on ground surface or at the bottom of water bodies to obtain a representative sample at the field station site.
    Date: 2021 (process 2 of 3)
    Sample preparation - After returning from the field, samples were air-dried, described, and photographed. This data release consists of post-field sample descriptions made by geologists. Photographs are not included in this dataset but are available on the DGGS website photo database (Athey and others, 2017). The data have not been reviewed for technical content and should be considered preliminary.
    Date: 2021 (process 3 of 3)
    Analytical methods - Data include geotechnical data, descriptions, and photographs. We followed conventions used in the Alaska Geotechnical Field Manual where appropriate. Attribute information includes moisture content, color based on six standard Munsell colors: light brown, yellowish-orange, greenish-gray, olive-gray, light gray, and dark gray, Unified Soil Classification System soil type (USCS), maximum grain (clast) size, material (clast) concentration, clast composition (mineralogy or lithology), coarse-grained particle angularity, presence or absence of organics, and reaction when treated with 10 percent hydrochloric acid (HCl) . The accompanying manuscript provides additional detail and a complete list of bibliographic references.
