Title:
Installation of environmental and hydrological monitoring stations-Utqiagvik-Wainwright-Atqasuk region, Alaska, August 2022
Abstract:
Installation of environmental and hydrological monitoring stations-Utqiagvik-Wainwright-Atqasuk region, Alaska, August 2022, Raw Data File 2023-21, provides information about hydrological and meteorological stations installed in northwestern Alaska between Utqiagvik, Atqasuk, and Wainwright in August 2022. During the summer of 2022, DGGS deployed multiple field crews to assess surface and subsurface resources as well as install equipment and collect environmental data in the Utqiagvik-Atqasuk-Wainwright region. The DGGS Hydrology Group focused primarily on installing environmental and hydrological stations, with a secondary objective of collecting riverbed profile and river discharge measurements. This report includes station descriptions and information about methods and equipment used at each location. These data and report are available from the DGGS website: http://doi.org/10.14509/31044.
Supplemental_Information:
hydro-instruments:    Type, location, and number of instruments installed at each station.	
soil-horizon-depth:    Snow node location and site descriptions.

Why was the data set created?

The ASTAR project is a collaborative effort initiated by the Alaska Department of Natural Resources (DNR) in partnership with the North Slope Borough to identify, evaluate, and advance opportunities to enhance the quality of life and economic opportunities in North Slope communities through infrastructure development.

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: 21-Aug-2022 (process 1 of 1)
    Instrument installation - We constructed seventeen stations between August 8 and 21, 2022, which consist of three 7-m weather towers, five 3-m tripod stream gage systems, and nine 2-m tripod snow nodes. Each weather tower hosts environmental sensors, a camera, and communication equipment. Each weather tower is accompanied by three snow-measurement nodes within one mile of the tower. The snow nodes are equipped to measure local snow-pack variability using downward-facing sonic sensors. However, environmental sensors such as air- and ground-temperature probes and ground-moisture sensors are also included on the snow nodes. Snow nodes were placed at locations which experience a variability in snow accumulation to capture local snow drifting or wind scouring most effectively. These installations required excavating approximately 1-m-deep pits, which provided an opportunity to inspect the subsurface composition and profiles at each site. Estimated soil horizons were determined using imagery taken of each excavation. Each node and gage station has a single ground moisture/temperature sensor and three temperature probes installed at different depths, commonly 25, 50, and 100 cm. Tower stations have two ground moisture/temperature sensors, along with a 1.25-m-long temperature profiler with two external probes installed at 5 and 10 cm, respectively.
