Dissolved and particulate combined carbohydrates, pH, inorganic ions, CDOM and particulate absorption of SML and bulk water in Arctic surface seawater and melt ponds

Arctic sea surface microlayer (SML) and bulk water samples were collected during the PASCAL campaign in the Fram Strait, Barents Sea and central Arctic Ocean on board the German icebreaker RV Polarstern from May until July 2017. SML samples were collected using the glass plate technique, corresponding bulk (subsurface) samples were collected at a defined depth of of 1 m, or at the bottoms of some closed melt ponds, using the telescopic rod method. Following types of water samples were diffentiated: ice-free ocean, leads/polynyas within the pack ice, the marginal ice zone (MIZ) and melt ponds. Following chemical parameters were determined: dissolved combined carbohydrates (DCCHO), particulate combined carbohydrates (PCCHO), pH, sodium, chloride, CDOM and particulate absorption. DCCHO concentrations were measured from filtered (0.2 µm) seawater after a desalination using electro-dialysis and high-performance anion exchange chromatography coupled with pulsed amperometric detection (HPAEC-PAD). PCCHO concentrations were measured from filters (0.2 µm polycarbonate membrane). DCCHO and PCCHO were determined as the sum of individual monosaccharides (e.g. arabinose, glucose, galactose, glucosamine, galactosamine, muramic acid, galacturonic acid, etc.). These data were collected to improve the understanding of the sea-air transfer of carbohydrates in this pristine environment. This data set is complimentary to previous measurements of the same samples published under following doi numbers: https://doi.org/10.1594/PANGAEA.899258 & https://doi.org/10.1594/PANGAEA.899284
