| contents | This collection contains: S1. Summary of radiocarbon-calibrated shell ages of Nuculana taphria and Parvilucina tenuisculpta estimated by amino-acid racemization (with 95% confidence intervals), with water depth (m), sampling year, and D/L of Aspartic and Glutamic acids. Both species were collected at PVL10-50 and OC-50 sites (southern California shelf). S2. Radiocarbon and calibrated ages and D/L of Aspartic and Glutamic acids of the nine specimens of N. taphria and seven specimens of P. tenuisculpta and used to calibrate the rate of amino acid racemization, plus information on live-collected specimens. Both species were collected at PVL10-50 and OC-50 sites (southern California shelf). S3. Boxcore and vibracore radiochemical data collected from the RV Melville, cruise MV1211. S4. Sediment grain size data for two boxcores and two vibracores from PVL10-50 and OC-50 sites (southern California shelf). S5. Estimates of shell loss of Parvilucina tenuisculpta and Nuculana taphria from the uppermost seabed increments based on one-phase exponential model (λ) and random-time two-phase exponential model (λ1, λ2, and sequestration τ) in the entire Southern California Bight and at two stations (PVL10-50 and OC-50). AICc refers to the Akaike Information Criterion corrected for small sample size. |
