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5741m岩芯,获得上新世(近5Ma)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。
International Integrated Ocean Drilling Program IODP323 voyage began on July 6, 2009 to September 4 in the Bering Sea. The main scientific goal of the voyage is to obtain a long time scale sedimentary sequence from the seabed sediment cores in the Bering Sea for the study of the Pliocene-Pleistocene sediment sequences from the Millennium scale to the Milankovi Odd-scale climate change and its linkages with the Pacific and the Arctic. After nearly 2 months of offshore drilling and research work, a total of 5741m cores were drilled at 7 wells to obtain core samples of different positions since the Pliocene (nearly 5Ma) and to obtain micro-organism and sedimentology Analyze the preliminary results of the test.
