Seasonal variability of organic matter composition in an Alaskan glacier outflow: insights into glacier carbon sources

Seasonal variability of organic matter composition in an Alaskan glacier outflow: insights into glacier carbon sources

Glacier ecosystems are a significant source of bioavailable, yet ancient dissolved organic carbon (DOC). Characterizing DOC in Mendenhall Glacier outflow (southeast Alaska) we document a seasonal persistence to the radiocarbon-depleted signature of DOC, highlighting ancient DOC as a ubiquitous featu...
