Dataset for: Dynamic deglacial evolution of interior seaways and ice streams in the Weddell Sea Embayment

Description

Supplement to: Bollen, MR, Gutjahr, M., Blaser, P., Ginnane, C., Klages, J.P., Müller, J., Turnbull, J.C., & Jaccard, S.L. (2026), "Dynamic deglacial evolution of interior seaways and ice streams in the Weddell Sea Embayment", Paleoceanography and Paleoclimatology This dataset contains: - detrital radiogenic isotope ratios (Nd, Pb) from near-surface sediment samples in the Weddell Sea and the sediment core PS111_53-2, - ramped-pyrolysis-oxidation radiocarbon analyses for sediment core PS111_53-2, - bulk physical properties of sediment core PS111_53-2 (shear strength, wet bulk density, fractional porosity). The dataset supports the figures, tables, and statistical analyses in the associated manuscript. Complete methodological descriptions are provided in the publication. Cores were recovered during RV Polarstern expeditions PS111, PS118, and PS128.
