GEOGRAPHIC REGION: western tropical Pacific PERIOD OF RECORD: 1891-1995 AD FUNDING SOURCES: (US) NSF, Lawrence Livermore National Laboratory DESCRIPTION: Nauru coral stable isotope timeseries. (166E, 0.5S, 14m bottom depth) Variable names DATE/OXYGEN-18O/CARBON-13C (time/per mil/per mil) LONGITUDE: 166E LATITUDE: 0.5S WATER DEPTH: 14m CORAL SPECIES: Porites australiensis and Porites spp. CORE LENGTH: 1.6 & 1.8 meters DATE OF COLLECTION: July 1995 Coral stable isotope analyses on untreated, low-speed drilled samples. Precision is ± 0.05 per mil as documented by an in-house homogenized coral standard, and presented relative to V-PDB (NBS-19 normalized). Oxygen isotope data has NOT been corrected for the acid fractionation difference ("acid-alpha") between standards (calcite) and coral samples (aragonite). Cores were taken from two ~2meter Porites corals on the north side of Nauru Island (166E 0.5S), 14m bottom depth, in July of 1995 by D. Schrag & M. Moore. Nauru-1 has been identified as Porites australiensis, Nauru-2 is Porites spp. Cores were split and cleaned with distilled water. Samples were drilled using a low-speed drill along the major vertical growth axis. Nauru-1 (1.85 meters) was sampled sequentially at 1 mm increments for the upper 750 mm, and 5mm continous samples for the remainder. Nauru-2 (1.61 meters) was sampled continously at 2 mm increments. Data is presented to time. The long Nauru-1 record (Nauru WDCA pt_3) is presented as a quarterly interpolated record, the least common sampling resolution of the whole sequence. There are three (3) data files in this submission. Nauru1.txt: Nauru-2 Full Coral Isotope Record (1898-1995) Nauru2.txt: Nauru-1 High-resolution Coral Isotope Record (1952-1995) Nauru3.txt: Nauru-1 Long Coral Stable Isotope Record (1892-1995) Nauru-2 Full Coral Isotope Record (1898-1995) Location: north side of Nauru Island (166E 0.5S) Species: Porites spp Water: 14 meters bottom depth Sampling methods: Cores split and cleaned with distilled water. The whole length sampled at 2mm (discrete) increments. Samples were not pretreated. Data normalized to V-PDB, ± 0.05 per mil. Oxygen isotope data has not been adjusted for the different acid fractionation between calcite (standards) and aragonite (coral). The coral's growth rate went from ~8mm/yr to ~21mm/yr and the lower, slow growing portion of the record (1898-1939) shows a strong kinetic overprint. Due to slow growth and early morphological changes 1900 is extremely truncated.

(1952-1995) Location: north side of Nauru Island (166E 0.5S) Species: Porites australiensis Water: 14 meters bottom depth Sampling methods: Cores split and cleaned with distilled water. This sequence sampled at 1mm discrete intervals (high-resolution). Samples were not pretreated. Data normalized to V-PDB, ± 0.05 per mil.

Stable Isotope Record (1892-1995) Location: north side of Nauru Island (166E 0.5S) Species: Porites australiensis Water: 14 meters bottom depth Sampling methods: Cores split and cleaned with distilled water. Upper 750mm at 1mm increments, remaining 1100mm at 5mm homogenizations. Samples were not pretreated. Data normalized to V-PDB, ± 0.05 per mil. Oxygen isotope data has not been adjusted for the different acid fractionation between calcite (standards) and aragonite (coral). This sequence is to time and has been quaterly equal interval interpolated, the least common resolution between the two different sampling resolutions. Prior to 1895/1896 the data exhibits a kinetic overprint.
