The objective of the proposed research is to improve our understanding of the mixing processes that drive vertical transports in the ocean. This topic is of critical interest, given the role of ocean circulation in governing Earth's climate through gas and heat exchange, as well as nutrient distributions and productivity in the gyres and near the coasts. Surveys of the small-scale and short-lived features that cause mixing in the ocean will be undertaken with a tow-yo vehicle (purchased with CFI New Initiatives funds) capable of sampling extremely quickly. Field work will be carried out in collaboration with Prof. Eric Kunze (UVic) who has microstructure profiling instruments, and with colleagues at DFO and internationally.

拟议研究的目的是提高我们对驱动海洋垂直运输的混合过程的理解。考虑到海洋环流通过气体和热交换在控制地球气候方面的作用，以及环流和海岸附近的营养分布和生产力，这一主题具有重要意义。对引起海洋混合的小规模和短暂特征的调查将使用拖曳车辆（由CFI新倡议基金购买）进行，能够极快地采样。现场工作将与Eric Kunze教授（UVic）合作进行，他拥有微观结构分析仪器，并与DFO和国际同事合作。
