Description:
Uranium series dated cold-water corals from Tropic Seamount, Reykjanes Ridge, and East Equatorial Atlantic. Ages are reported in years before present (BP; where present is the year of 1950 CE) both uncorrected and corrected for initial 232Th. Some samples did not pass our quality control. Selection code column indicates samples not included on age distribution discussion: [238U] 〈2 ppm (Low U), [232Th] 〉6 ppb (High Th), [δ234Ui] 〉157‰ (High δU) and lowest quality sub-sample (duplicate).
