Collaborative Research: Reconstructing Holocene Climate Variability and the Indonesian Throughflow in the Western Equatorial Pacific

摘要：本提案要求支持从印度尼西亚区域收集一系列高累积率岩心。 分析的核心将被用来记录在西太平洋暖池和印度尼西亚通流的百年-千年的变化的性质。 现场项目将从沿着印度尼西亚贯穿流的主要路线（包括马卡萨尔海峡、苏拉威西海和帝汶海峡）约200 m水深处开始，获取一系列深度剖面岩心。 巡航后分析计划将侧重于使用南极有孔虫氧同位素测量和AMS 14 C测年法为选定的岩心建立基本地层框架。 此外，表层沉积物样品将用于浅水底栖有孔虫Mg/Ca的初步温度校准研究。

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.
