Title:
Punta Pitt Stable Isotope and Ion Data (delta 18O, delta 13C, Cd/Ca, Mn/Ca) for 1936 to 1982.5
Abstract:
File contains data presented by Shen et al. (1992a). Table includes d18O, d13C, Cd/Ca, Mn/Ca, and Ba/Ca data from a 2m coral head and, for comparison, SST records from Academy Bay (Galapagos; 0 deg 40 min S, 90 deg 20 min W). All coral measurements derive from the same samples, which were treated as described in Shen et al. (1992a). Stable isotopes were measured at Lamont-Doherty Earth Observatory by J. Cole and R. Fairbanks on a Finnigan MAT-251 mass spectrometer with automated Carousel-48 carbonate device; values are in standard per mil notation relative to PDB. Cd/Ca and Mn/Ca were measured at the University of Washington by G. Shen and L. Linn on a Hitachi Z-9000 multichannel atomic absorption spectrophotometer. Ba/Ca was measured at the University of California/Santa Barbara by D. Lea on a VG Elemental PQ2+ inductively coupled plasma mass spectrometer. Measurement precisions are as follows: 0.08 d18O; 0.04 d13C; 9.8% for Cd/Ca; 6.6% for Mn/Ca; 1% for Ba/Ca. Ages for samples were assigned on the basis of well-defined density banding, assuming that the base of the dense band corresponds to February and that extension rates between these points are linear. Coral measurements were made at quarterly resolution. SST records were averaged from monthly resolution to quarterly based on the following 3-month groupings: Feb-Mar-April, May-June-July, Aug-Sep-Oct, and Nov-Dec-Jan.
