AVA-AK: Prudhoe Bay ArcSEES Airport Study (Walker et al. 2016)

Arctic Vegetation Archive - Alaska: Prudhoe Bay ArcSEE Airport Study.

This dataset consists of vegetation and environmental data from 26 plots at the Prudhoe Bay Airport Site, near the Deadhorse Airport, Alaska. The Prudhoe Bay Airport Site was established in 2015 at the northern end of the Dalton Highway, as a part of the NSF Funded ArcSEES (Arctic Science, Engineering, and Education for Sustainability) project titled: “Cumulative effects of Arctic oil development — planning and designing for sustainability” (award no. 1233854) with partial funding from the NASA Land Cover Land Use Change (LCLUC) program (award no. NNX14AD906).

The principal goals of the ground-based studies were to document and analyze the long-term (1949–2015) changes to vegetation, soils, and permafrost caused by road- and climate-related impacts. Methods and data from the Airport site are fully described in AGC Data Report 16-01 (Walker et al. 2016). A similar set of 29 vegetation plots was established near Lake Colleen, approximately 3 km NNW of the Airport Site in 2014 (AGC Data Report 15-01, Walker et al. 2015). A third AGC data report includes temperature and snow data from the vegetation plots and additional transect data from both sites (Walker et al. 2018)

The 26 (one plot had 2 subplots (A and B)) 1 x 1-m vegetation plots are located along side three transects in low-centered polygonal tundra that have been heavily impacted by road-related disturbances, including road dust, road-side flooding, road-related snow beds, old gravel roads, buried utility cables, and off-road vehicles. The original vegetation was most likely dominated by two main vegetation types: 1) a moist sedge, prostrate-shrub, moss tundra (U3), and a wet sedge, moss tundra(M2) both described in early vegetation research in the Prudhoe Bay region (Walker et al. 1980; Walker 1985; Walker and Everett 1991). Plots were permanently marked with short wooden stakes. In the center of each plot is an 18 inch (46 cm) piece of 3/8 inch (1 cm) diameter steel rebar rod with plot number engraved on the aluminum cap that marks the photo point. Additional data obtained from or adjacent to the plots include soil physical, chemical and descriptive data, soil and air temperatures, photographs and spectral data (leaf area index (LAI) and normalized difference vegetation index (NDVI).

The report Walker et al. (2016) also includes additional data not contained in the Alaska Arctic Vegetation Archive. These data include information from sample points taken at 1-m intervals along the transects, such as thaw and water depths, LAI and NDVI, vegetation type (following Walker et al. 1980 with additional new types described in Walker et al. 2016), microrelief features, latitude and longitude, elevation, and gravimetric moisture content of soil samples from boreholes drilled in ice-wedge polygonal centers along with thicknesses of frozen protective layers above massive-ice bodies in boreholes.
