Abstract:
This dataset provides the harmonized age-depth model for marine sediment record SO201-2-114KL from the Bering Sea (59.230°N, 166.990°E; water depth 1376 m). The modeled interval spans approximately 9,944 to 18,604 calibrated years BP. Published chronology constraints were screened for traceability and suitability and grouped into 9 independent dated-depth clusters. This record is an explicit legacy chronology and is not a unified Marine20 reconstruction. Published calibrated calendar-age constraints are passed to Bacon with cc = 0 under the legacy treatment; no new Marine20 recalibration of the underlying radiocarbon measurements is claimed. 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.
