The fate of permafrost carbon upon thaw will drive feedbacks to climate warming. Here we consider the character and context of dissolved organic carbon (DOC) in yedoma permafrost cores from up to 20 m depth in central Alaska. We observed high DOC concentrations (4 to 129 mM) and consistent low molecular weight organic acid concentrations in three cores. We estimate a DOC production rate of 12 μmol DOC m À2 yr À1 based on model ages of up to~200 kyr derived from uranium isotopes. Acetate Cdoi:10.1002/2015gl066296 fatcat:eqqqf5xtbjbgfovyflollhxpry
