Here we compare coral oxygen isotopic (d18O) series (spanning A.D. 1997-1780 and A.D. 2001-1776) from two genera of hermatypic corals in Fiji, located within the SPCZ, to examine the fidelity of these corals in recording climate change and SPCZ interdecadal dynamics. One of these coral records is a new 225-year subannually resolved d18O series from the massive coral Diploastrea heliopora. Diploastreas use in climate reconstructions is still relatively new, but this coral has shown encouragingly similar interannual variability to Porites, the coral genus most commonly used in Pacific paleoclimate studies. In Fiji we observe that interdecadal d18O variance is also similar in these two coral genera, and Diploastrea contains a larger-amplitude interdecadal signal that more closely tracks instrumental-based indices of Pacific interdecadal climate change and the SPCZ than Porites. Both coral d18O series record greater interdecadal variability from ~1880 to 1950, which is consistent with the observations of Folland et al. (2002), who reported higher variability in SPCZ position before 1945. These observations indicate that Diploastrea will likely provide a significant new source of long-term climate information from the SPCZ region. #-------------------- # Funding_Agency #-------------------- # Site_Information # Site_Name: Savusavu, Fiji # Location: Ocean>Pacific Ocean # Region: PAGES Australasia 2k # Country: Fiji # Northernmost_Latitude: -16.82 # Southernmost_Latitude: -16.82 # Easternmost_Longitude: 179.23 # Westernmost_Longitude: 179.23 # Elevation: -2 #-------------------- # Data_Collection # Collection_Name: Coral d18O for PAGES Australasia 2k regional reconstructions # Earliest_Year: 1776 # Most_Recent_Year: 2001 # Time_Unit: AD # Notes: These may be processed data.
