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地区收集一系列高积累率岩芯。对岩心的分析将被用来记录西太平洋暖池和印度尼西亚贯穿流百年-千年变化的性质。该实地计划将获得一系列深度横断面岩心，从大约200米水深开始，沿着包括马卡萨海峡、苏拉威西海和东帝汶海峡在内的印尼贯通水流的主要路线。巡航后的分析计划将侧重于利用浮游有孔虫的氧同位素测量和AMS 14C测年，为选定的岩心建立基本的地层框架。此外，表层沉积物样品将用于浅水底栖有孔虫Mg/Ca的初始温度校准研究。

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.
