#	Description: Nauru coral stable isotope timeseries. (166E, 0.5S, 14m bottom depth)  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.

#       Abstract: Stable isotope analysis of two separate corals from Nauru Island in the warm pool of the western tropical Pacific confirm that coral oxygen isotopes are a robust recorder of environmental variables. Coral δ18O faithfully records interannual variability even when strongly influenced by kinetic effects. Interannual to decadal variability of coral δ13 remains enigmatic; only one of the two corals exhibits the expected light-δ13C response in the interannual band. Coral δ18O from this region has a great similarity to global instrumental temperature records reflecting the impact of the Pacific warm pool and variations of the Indonesian Low in concert with El Niño-Southern Oscillation on global climate. Since 1896, coral δ18O has exhibited a cumulative decrease of 0.7‰, which reflects a combination of warming and more frequent El Niño events (precipitation) affecting the surface waters of this region.

#	Time_Unit: AD
#	Core_Length: 1.61 m
#	Notes: Core name- Nauru-2. Oxygen isotope data has NOT been corrected for the acid fractionation difference ("acid-alpha") between standards (calcite) and coral samples (aragonite). 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.
