Study Site: Scotty Creek Field Station near Fort Simpson, Northwest Territories
Purpose: Lakes in discontinuous permafrost peatlands are on the front lines of climate change, sensitive to even modest increases in air temperature. The aim of this study was to provide the first limnological characterization of shallow (∼1–2 m depth) lakes in the Scotty Creek basin (Northwest Territories, Canada), a field site of circumpolar significance due to the existence of long-term ecohydrological monitoring going back decades.
Abstract: Limnological data for small, shallow lakes at or near the Scotty Creek Field Station near Fort Simpson, Northwest Territories, Canada. It includes: (1) surface water chemistry and subfossil diatom (Bacillariophyta) assemblages in 16 lakes at or near Scotty Creek collected in mid-July, 2018; (2) high-resolution logger data for depth, oxygen, light, and temperature profiles over the 2019 ice-free season in First Lake and Goose Lake at the Scotty Creek Research Station; (3) buffer and overlay landscape analysis of fen and collapse scar area within a 250 m buffer of lake shorelines for 9 lakes in the Scotty Creek basin; (4) Water chemistry and subfossil diatom assemblages in wetlands and substrate samples (submerged vegetation, submerged peat, sediment, and grasses) from shoreline environments around Goose Lake, collected in June, 2019.
