In July 2003, we departed from Jakarta, Indonesia aboard the R/V Baruna Jaya VIII for 25 days to investigate Holocene tropical climate. This expedition was named the Collaborative Oceanic Research expedition in the Indonesian Throughflow (CORE-IT). Aboard the vessel, we deployed multicore and gravity core equipment to collect sediments along with collecting surface and deep seawater samples. The CORE-IT group consisted a contingency of scientists from Indonesia, Woods Hole (Co-PI-Delia Oppo), and SUNY-alabany (Co-PI-Brad Linsley), along with Rutgers, including specifically-Co-PI Yair Rosenthal, Research Technician-Suzanne Perron, Former post-docs-Carrie Lear, Thibault deGaridel Thoron, and Dyke Andreasson.
