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.
Intact polar lipid fatty acids were extracted from the sediments, purified, and 14C analysis was performed as described in Ruben et al. (2023). The 13C isotopy was determined with GC-IRMS (Elvert et al., 2003).-138.943794469.57320278Herschel Island, Yukon Territory, CanadaHorizon 2020https://doi.org/10.13039/501100007601773421NUNATARYUK, Permafrost thaw and the changing Arctic coast, science for socioeconomic adaptation
