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, Michael
Lake 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).
