Question

Applying this technique to Crypto·meria japonica reveals at least five SEP events named for Fusa Miyake. This technique uses standards in the IntCal series and is complemented by a calculation involving the standard PDB ratio obtained from the Pee Dee Belemnite. Measurements in this technique are depressed by the emissions-driven Suess effect and are inflated by the marine reservoir (20[1])effect. Willard Libby won a Nobel for this technique (0[1])that accounts for a (*) "bomb pulse" from when nuclear tests altered atmospheric concentrations. (10[1])Calibration (10[1])curves for this technique are produced by applying it (10[1])to tree rings. For 10 points, name this technique (10[1])that uses the 5,730-year (10[1])half life of a 14-dalton isotope to measure age. ■END■ (10[1])
