Ecological Survey of Soil Probe Depth, Plant Functional Type (PFT) Coverage, and Vegetation PFT Height around an Eddy Covariance Tower near Resolute, Nunavut (NU) (July 2025)

An ecological survey was conducted July 23 - 28th, 2025 to characterize the landscape around an eddy covariance tower site located near Resolute Bay, NU (74.7279, -94.8985). The tower was installed in 2024 by Woodwell Climate Research Center and is now operated by Woodwell as part of the Permafrost Pathways Arctic Carbon Monitoring program. All eddy covariance tower measurements will be made available on the Ameriflux website (AMF site ID: CA-RSB). The site is described as polar desert, located on a gentle slope underlain by rocks and gravel with some sparse grasses, forbs, and mosses. Sampling plots were established every 10 - 20 meters (m) along 100 m transects extending north, east, south, and west from the tower. Surveys included soil probe depth (attempted thaw depth measurements but the landscape is underlain by rocks and gravel) and vegetation surveys of 50 centimeter (cm) x 50 cm plots to determine PFT coverage and PFT height. Photos of vegetation plots included.
