This proposal is to conduct a purposeful Tracer Release Experiment (TRE) in the North Atlantic Ocean as a component of the World Ocean Circulation Experiment (WOCE). The PI will systematically release sulfur hexafluoride at predetermined depths in the ocean and periodically revisit the area to measure its distribution. Additional supporting observations of the internal wave and microstructure climate will be made. From these, a measure of the mixing rates may be determined. Ocean mixing rates are essential ingredients in models of the circulation.

这项提议是作为世界海洋环流实验(WOCE)的一个组成部分，在北大西洋进行有目的的示踪剂释放实验(TRE)。PI将系统地在海洋中预定的深度释放六氟化硫，并定期重新访问该地区，以测量其分布。将对内波和微结构气候进行额外的辅助观测。由此可以确定混合率的量度。海洋混合率是环流模型中的基本要素。
