Studying Ventilation in the Seas of Japan and Okhotsk Using Tritium and 3He

9633276 詹金斯 在这个项目中，PI将分析1995年3月至4月在日本海和鄂霍次克海获得的一系列水样。华盛顿大学的里瑟在一艘俄罗斯研究船上。 将特别注意氦-3和氚的分析。 结果将被用来作为循环模型的限制，估计耗氧率，并推断出口生产率内的盆地。 这些海洋被认为是北太平洋中间沃茨（NPIW）通风的主要来源，因此对于各种海洋学和气候原因都很重要。 研究结果将有助于为整个北太平洋的示踪剂模型提供边界条件，增加世界海洋环流实验太平洋示踪剂方案的价值。

9633276 Jenkins In this project, the PI will analyze a series of water samples obtained in March-April, 1995 in the Seas of Japan and Okhotsk by Dr. S. Riser, of the University of Washington, aboard a Russian research vessel. Specific attention would be paid to analysis for Helium-3 and Tritium. Results would be used as circulation model constraints, to estimate oxygen consumption rates, and to infer rates of export production within the basins. These seas are thought to be the principal sources of ventilation of North Pacific Intermediate Waters (NPIW), and hence important for a variety of oceanographic and climatic reasons. Results would be useful in providing boundary conditions for tracer models of the entire North Pacific, adding value to the Pacific tracer program of the World Ocean Circulation Experiment.
