Intact polar lipid concentrations of sediment core YC22_MR_7 off Herschel island (Yukon Coast 2022)

DOI

In July 2022 within the framework of an Alfred-Wegener-Institute-managed expedition and the Nunataryuk project, sediment core YC22_MR_7 was taken off the coast of Herschel Island, Canada, using a hand corer. Data sets were obtained to investigate carbon feedback from the sediments to the water column and atmosphere, using DIC concentrations and isotopic values. The local sediments are supplied primarily by organic carbon previously stored in adjacent permafrost soils (biomarker and bulk data), which erode and redeposit quickly (age model) on the ocean floor.The precursor lipids of the polar fractions used for isotope analysis were quantified following the method described in Wörmer et al. (2013). Quantified lipid classes include: betaine lipids (BL), phosphatidyl-(N)-monomethylethanolamine (PME), phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), diphosphatidylglycerol (DPG) and lyso-DPG.
