Core 4F1 was collected in 10 meters of water and spans 1940 to 1997, while core LH was collected in 2 meters of water and we present here only the period 1940 to 2001. The composite d18O and Sr/Ca records are an average of the two cores, both normalized to the 1970-1996 mean. Both cores were sampled at 0.5 mm intervals within the upper 50 mm, and at 1 mm intervals below 50 mm depth. #-------------------- # Publication # Authors: Bagnato, S.; Linsley, B.K.; Howe, S.S.; Wellington, G.M.; Salinger, J. # Published_Date_or_Year: 2004 # Published_Title: Evaluating the use of the massive coral Diploastrea heliopora for paleoclimate reconstruction. # Journal_Name: Paleoceanography # Volume: 19 # Edition: # Issue: PA1032 # Pages: # DOI: 10.1029/2003PA000935 # Online_Resource: # Full_Citation: Bagnato, S., B.K.

The Indo-Pacific coral genus Diploastrea, however, owing to its slower extension rate, denser structure, and longer lifespan, can potentially preserve geochemical proxy records 2�3 times longer than Porites cores of the same length. Before its potential can be realized, Diploastrea must first be calibrated and its climate signal assessed. We present oxygen isotope (d18O) and Sr/Ca results from two Diploastrea cores collected in Fiji (16�49S, 179�14E) that allow for simultaneous evaluation of this coral's paleoclimatic utility and the reproducibility of each tracer at this site. Comparison to a Porites record from the same location allows for further evaluation of Diploastrea as a paleoclimatic archive. We demonstrate that Diploastrea's septal and columellar material yield similar d18O-SST relationships and that despite some sacrifice of the seasonal d18O amplitude, bulk sampling of either region is satisfactory for resolving interannual and lower frequency modes of climatic variability. Therefore paleoclimate reconstructions employing either a septal or columellar sampling regime of this genus may be useful at filling in spatial and temporal sampling gaps which currently hinder the reconstruction of long-term changes in major climate fields in the western Pacific. #------------------ # Funding_Agency # Funding_Agency_Name: # Grant: #------------------ # Site_Information #
