An Abrupt Aging of Dissolved Organic Carbon in Large Arctic Rivers

Permafrost thaw in Arctic watersheds threatens to mobilize hitherto sequestered carbon. We examine the radiocarbon activity (F(14)C) of dissolved organic carbon (DOC) in the northern Mackenzie River basin. From 2003–2017, DOC‐F(14)C signatures (1.00 ± 0.04; n = 39) tracked atmospheric (14)CO(2), ind...
