Abstract:
This dataset provides the harmonized age-depth model for marine sediment record MD01-2416 from the open subarctic North Pacific (51.270°N, 167.730°E; water depth 2317 m). The modeled interval spans approximately 10,844 to 18,984 calibrated years BP. Published radiocarbon determinations were screened for traceability and suitability, grouped into 28 independent dated-depth clusters, and recalibrated with Marine20 using a regional reservoir correction of ΔR = 260 ± 200 yr before Bayesian age-depth modeling with Bacon. The published table contains the canonical 201-point posterior age product used in the North Pacific chronology framework, including posterior age estimates and chronological uncertainty through the modeled interval. The reconstruction is intended to provide a traceable and methodologically consistent chronology for comparison with other subarctic North Pacific sediment records; the accompanying bundle documents input provenance, exclusions, model settings, diagnostics, and interpretation limits.
