Boyle, Coralline barium records temporal variability in equatorial Pacific upwelling, Nature, 340, 373-376. GEOGRAPHIC REGION: Galapagos Islands PERIOD OF RECORD: 1963-82 LIST OF FILES: GALAPBA.DAT DESCRIPTION: Site: Punta Pitt, Isla San Cristobal, Galapagos Islands, Ecuador (0 40'S, 89 10'W) Water depth 14m Coral species Pavona clavus Time span: 1963-82 at quarterly resolution File contains Ba/Ca data (in mmol/mol) presented by Lea et al. (1989). Samples were measured at the Massachusetts Institute of Technology by D. Lea. Ba determinations were performed on a VG PlasmaQuad inductively coupled plasma mass spectrometer, and Ca was determined by flame atomic absorption. Measurement precision is 1% for Ba/Ca. Ages for samples were assigned on the basis of well-defined density banding. Annual growth averaged 11mm/yr.
