Brief communication: Stream microbes preferentially respire young carbon within the ancient glacier dissolved organic carbon pool

Brief communication: Stream microbes preferentially respire young carbon within the ancient glacier dissolved organic carbon pool

<p>Glaciers export ancient bioavailable dissolved organic carbon (DOC). Yet, the sources of organic carbon (OC) underpinning bioavailability are poorly constrained. We assessed the isotopic composition of respired OC from bioincubations of glacier DOC. Relative to bulk DOC, respired OC was you...
