P17N: A WOCE Hydrographic Program Section in the Northeast Pacific

在这个项目中，PI将收集和解释东北太平洋高质量和高分辨率的电导率、温度、深度、氧气和营养数据，沿着世界海洋环流实验(WOCE)指定的P-17N线，从旧金山到舒马金群岛的海岸大致平行，并与阿拉斯加的锡特卡相交。要解决的具体科学问题包括热量和淡水分歧、阿拉斯加环流和亚热带环流之间的性质交换、北太平洋中间水的扩散和通风率，以及从二氧化硅分布中看到的海底边界相互作用。

In this project the PI's will collect and interpret high-quality and high-resolution conductivity, temperature, depth, oxygen and nutrient data in the Northeast Pacific Ocean, along a line designated as P-17N by the World Ocean Circulation Experiment (WOCE), and running generally parallel to the coast from San Francisco to the Shumagin Islands, with an intersecting leg into Sitka, Alaska. Specific science issues to be addressed include heat and fresh water divergences, exchange of properties between the Alaska Gyre and the Subtropical Gyre, spreading and ventilation rates of North Pacific Intermediate Water, and bottom boundary interactions as seen in silica distributions.
