Keigwin The PI will conduct paleontological and isotopic studies of changing hydrographic and climatic conditions since the last glacial maximum (LGM) in the Okhotsk Sea and will attempt to link these results to earlier reconstructions from the open Pacific. Testing the hypothesis that nutrient-depleted watermass existed during LGM in NW Pacific at 2300 m depths is also an objective. Cores collected from the Okhotsk Sea in 1993 will be used for the study. Collaboration with a Russian scientist from the Pacific Oceanological Institution at Vladivostok is planned.

凯格温号将对鄂霍次克海自上一次冰川盛期(LGM)以来不断变化的水文和气候条件进行古生物学和同位素研究，并将试图将这些结果与早期从开阔的太平洋重建的结果联系起来。对西北太平洋2300米深度LGM期间存在营养耗竭水团的假设进行检验也是一个目的。1993年从鄂霍次克海采集的岩芯将用于这项研究。计划与符拉迪沃斯托克太平洋海洋研究所的一名俄罗斯科学家合作。
