Project Reconstructing Tropical Pacific climate variability, and monsoon systems and abrupt changes from ice cores on Irian Jaya, Indonesia and Hualcan, Peru
 Principal Investigator  Dr. R. Dwi Susanto (LDEO of Columbia University, New York)
 US-Grant  National Science Foundation (NSF)
 Collaborators
Ohio State Univ. Lonnie  G. Thompson and Ellen Mosley-Thompson, Byrd Polar Research Center
Indonesia  Dr. Sriworo Harijono, Agency for Meteorology, Climatology and Geophysics (BMKG), Jakarta
 Objectives
 *  To reconstruct the regional history of temperature and precipitation and thus to produce a high resolution record of Asian monsoon/El Niño-Southern Oscillation (ENSO) variations
*  To document the ice thickness and calculate ice volumes
*  To explore the potential to produce black carbon and fire histories from these ice cores as possible ENSO markers
*  To determine a possibility of Papua ice core history as a proxy of the Indonesian throughflow

 Figure 1. Sea surface temperature during La Nina condition in November 1998 (top) and El Nino condition in November 1997 (bottom). Stars represent location of ice cores in either side of Pacific ocean (Papua-Indonesia and Haulcan-Peru). Ice cores in both places may reveal ENSO conditions in the last 5000 years depending on the ice thickness.
