Madang Lagoon, Papua New Guinea Fossil and Living Coral Isotope (delta 18O) Data for 130,000 years BP to Present
Entry ID: G2108

Abstract: Results of analysis of a core collected from a living massive Porites coral on
Deplik Tabat reef, Madang Lagoon, Papua New Guinea. The core was collected
vertically down the axis of maximum growth of the colony. This core was
subsampled into 2mm growth increments, resulting in an average of 6
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
