Item Open Access Dataset: Climatic Drivers of Limnological Change in Iqallukvik Lake, Tuktoyaktuk, Northwest Territories, Canada(2022) Gruia, Sorin-Alexandru; Thienpont, Joshua; Coleman, Kristen; Korosi, JenniferItem Open Access Limnology and diatom ecology of shallow lakes in a rapidly thawing discontinuous permafrost peatland(2023-01-01) Coleman, Kristen; Korosi, JenniferLimnological 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. Data accompanies Kristen Coleman’s PhD dissertation (York, Geography).Item Open Access Water chemistry and sediment core data from small, shallow lakes of the Taiga Plains (Northwest Territories, Canada)(2025) Korosi, Jennifer; Coleman, Kristen; Thienpont, Joshua; Palmer, MichaelLake browning has been widely projected for northern lakes affected by permafrost thaw, but the inherent heterogeneity in permafrost landscapes coupled with a paucity of data for many regions makes it challenging to develop circumpolar-scale assessments. This dataset provides surface water chemistry from 35 small, shallow (0.5-3 m) lakes in discontinuous permafrost peatlands of the Taiga Plains (Northwest Territories, Canada), which were distributed across two Level IV ecoregions (Cameron Uplands, Tathlina Plain). This dataset also provides a comparison subfossil diatom assemblages between present-day (2012-2018) and ~1850 in 23 Taiga Plains lakes distributed across three Level IV ecoregions (Cameron Uplands, Tathlina Plain, South Mackenzie Plain).
