Age model of sediment core YC22_MR_7 off Herschel island (Yukon Coast 2022)

Description
Summary: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. Sedimentary age model of core YC22_MR_7 assuming Constant Flux: Constant Sedimentation (CFCS) model (Appleby, 2001), based on data obtained with a HPGe gamma detector.
