Laing Island, Papua New Guinea Fossil and Living Coral Isotope (delta 18O) Data for 130,000 years BP to Present
Entry ID: G2109

[ Get Data ]

Abstract: Results of analysis of a core collected from a living massive Porites coral
on a reef immediately north of Laing Island, Papua New Guinea. The core was
collected vertically down the axis of maximum growth of the colony.
This core was subsampled into 1mm growth increments, resulting in an average
of 9 samples/annual growth increment. These samples were analysed for d18O,
then the data interpolated to seasonal resolution (presented here).
In this region, seasonal and interannual variations in skeletal d18O are due
to the combined effects of changes in precipitation/evaporation balance and
temperature; see Tudhope et al., 1995, Earth Planet. Sci. Lett., 136, 575,
and Tudhope et al., 2001, Science, 291, 1511-1517 for further discussion of
climatic interpretation.
