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

9633276 Jenkins在这个项目中，PI将分析1995年3-4月在日本海和鄂霍次克获得的一系列水样，这些水样是华盛顿大学的S.Riser博士在一艘俄罗斯考察船上获得的。将特别注意氦-3和氚的分析。结果将被用作循环模型约束，以估计氧气消耗率，并推断盆地内的出口生产率。这些海域被认为是北太平洋中间水域(NPIW)的主要通风来源，因此由于各种海洋学和气候原因而变得重要。结果将有助于为整个北太平洋的示踪模式提供边界条件，为世界海洋环流实验的太平洋示踪计划增加价值。

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.
