国际综合大洋钻探计划IODP323航次于2009年7月6日开始至9月4日结束在白令海实施。该航次的主要科学目标是通过钻取白令海的海底沉积物岩心样品,获得高纬度边缘海的较长时间尺度沉积序列,用于研究该海区上新世—更新世的从千年尺度到米兰科维奇尺度气候变化及其与太平洋和北冰洋的关联。经历近2个月的海上钻探与研究工作,在7个井位上共钻取5 741 m岩芯,获得上新世(近5 Ma)以来的不同位置岩芯样品,并取得微体古生物与沉积学等分析测试的初步结果。

The Integrated Ocean Drilling Program (IODP) 323 was successfully carried out in the Bering Sea during July 6 to September 4, 2009. This expedition was aimed to drill in the Bering Sea for obtaining long time-scale sedimentary sequences, and studying the Pliocene-Pleistocene evolution of millennial to Milankovitch- scale climatic oscillations in the Bering Sea, the marginal sea connecting the Pacific and Arctic Oceans. After drilling and analyzing on the sea, a total of 5741m long core samples had been recovered from 7 sites of different geographic locations, getting the primary scientific results by using modern micropaleontologic and sedimentologic methods.
