Summary: This proposal requests support to collect a series of high accumulation rate cores from the Indonesian region. Analyses of the cores will be used to document the nature of centennial-millennial variability in the Western Pacific Warm Pool and Indonesian throughflow. The field program will obtain a series of cores in depth transects beginning at about 200m water depth along the main route of the Indonesian throughflow including the Makassar Strait, Sulawesi Sea and Timor channels. The post cruise analytical program will focus on establishing a basic stratigraphic framework for selected cores using planktic foraminifer oxygen isotope measurements and AMS 14C dating. In addition surface sediment samples will be used for an initial temperature calibration study on shallow water benthic foraminifer Mg/Ca.

摘要：该提案请求支持从印度尼西亚地区收集一系列高积累率核心。 对岩心的分析将用于记录西太平洋暖池和印度尼西亚径流量百年一千年变化的性质。 该现场计划将在印度尼西亚通流主要路线（包括望加锡海峡、苏拉威西海和帝汶航道）的约200m水深处开始获得一系列深度横断面岩心。 巡航后分析计划将侧重于利用浮游有孔虫氧同位素测量和 AMS 14C 测年为选定的岩心建立基本地层框架。 此外，表面沉积物样品将用于浅水底栖有孔虫 Mg/Ca 的初始温度校准研究。
