Description: This dataset provides the dissolved organic carbon (DOC) concentrations of the organic matter (OM) obtained from glacier purple ice- and red snow-algae dominated samples collected upwind of the DEEP PURPLE ice camp (deeppurple-ercsyg.eu) on the surface of the Greenland Ice Sheet. The samples are represented by the initial OM from glacier ice- (T0_Ice) and snow-algae (T0_Snow) dominated habitats and the up to 24 days (T3-T24) in situ incubated samples under dark (D) and light (L) conditions. OM samples, include dissolved organic matter (DOM) and particulate organic matter (POM), the latter extracted with hot water (HW) and sodium hydroxide (Na) to represent water-soluble and particle-associated OM, respectively (see methods). Dissolved organic carbon concentrations were determined as non-purgeable organic carbon obtained from replicate measurements of DOM and POM extracts analyzed in a Shimadzu high-sensitivity TOC-V analyzer. The concentrations in this dataset are part of the supplementary material in Rossel et al. (2025).
