Data from: Abrupt stream acidification and metal mobilization from permafrost degradation

This dataset includes stream chemistry, stream discharge, and seepage chemistry in headwaters of the Yukon-Mackenzie river divide. It also includes a compilation of acid seeps, vegetation dieback, and "rusty streams" (defined as streams visibly impacted by iron precipitation using remote sensing). The dataset documents abrupt acidification and metal mobilization in Central Yukon. It accompanies a paper by the same authors with the same name as the dataset published in the journal Science (Skierszkan et al., 2026; science.org/doi/10.1126/science.aea2898).
