Fire biomarkers (levoglucosan, mannosan, and galactosan) recorded in the deep Denali, AK ice core from ~360 to 2013 CE
Monosaccharide anhydrides (MAs), or anhydrosugars which include levoglucosan, mannosan, and galactosan are combustion products of cellulose and hemicellulose that are used as biomass burning tracers. These fire biomarkers are incorporated into smoke plumes, transported through the atmosphere, and return to the surface …
