OPP 95-28349 PI: P. SCHLOSSER This proposal requests funds for collection, measurement, and interpretation of about 200 tracer element (Tritium, Helium, Oxygen, CFC's) samples in the framework of the planned 1996 Arctic Ocean submarine cruise. The work will be focused on a broad survey of the upper waters in the Canadian Basin. Results from a previous submarine cruise (USS PARGO, 1993) demonstrated the feasibility of obtaining high-quality transient tracer samples from surface stations. The measurements will be used, together with hydrographic data, to (1) study the transport of shelf waters into the Arctic halocline, (2) derive evolution, circulation patterns, and mean residence times of the upper waters in the Canadian Basin, (3) delineate pathways and storage times of river runoff and sea-ice meltwater in the upper layers of the Canadian Basin, and (4) to validate Arctic Ocean circulation models.

OPP 95-28349 PI：P.Schlosser本提案要求在计划的1996年北冰洋潜艇巡航框架内收集、测量和解释约200000个示踪元素(氚、氦、氧、氯氟化碳)样品。这项工作将集中在对加拿大盆地上游水域的广泛调查上。前一次潜艇巡航(美国帕戈号航空母舰，1993年)的结果表明，从水面站获得高质量的瞬时示踪剂样品是可行的。这些测量数据将与水文学数据一起用于：(1)研究陆架水进入北极盐跃层的输送；(2)得出加拿大盆地上层水的演变、环流模式和平均停留时间；(3)圈定加拿大盆地上层河流径流和海冰融化的路径和储存时间；(4)验证北冰洋环流模型。
