Project Reconstructing Tropical Pacific climate variability, and monsoon systems and abrupt changes from ice cores on Irian Jaya, Indonesia and Hualcan, Peru
Principal Investigator R. Dwi Susanto, Ph.D.
Grant National Science Foundation (NSF), USA
Collaborators Lonnie G. Thompson and Ellen Mosley-Thompson, Byrd Polar Research Center, Ohio State University, USA

Dr. Sriworo Harijono, Agency for Meteorology, Climatology and Geophysics (BMKG), Jakarta, Indonesia.
Objectives To reconstruct the regional history of temperature and precipitation and thus to produce a high resolution record of Asian monsoon/El NiƱo-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.
