Lead 210, Caesium 137 and grain size of sediment, Carbon 14 and amino acid racemization data of two bivalves from two cores from Palos Verdes Shelf and San Pedro Shelf, California

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).
