Ventilation of the Western Arctic Halocline via Boundary Processes

观测表明，北极西部的盐跃层是由源自大陆架的沃茨通风（补充）的。这种通风过程对北冰洋的物理、生物和化学系统至关重要。人们对这种通风在北极西部发生的地方知之甚少，是什么控制了它的大小，它是如何发生的，或者它如何在不断变化的气候中变化。提供资金，以更好地了解这个通风过程中，在加拿大南部盆地使用区域，高分辨率的海洋冰模型。模型计算将允许边界-内部交换的详细检查，将陆上通量与楚科奇海和南博福特海的特定动力学过程和区域联系起来，并为测试这种交换的理论约束提供基础。模型设计、评估和分析将与作为北极西部陆架-海盆相互作用计划一部分收集的数据密切相关。这将提供一个有价值的测试模型字段，以及激励模型分析，以解决问题的通风过程中，不能单独解决的数据。

Observations indicate that the western Arctic halocline is ventilated from (replenished by) waters that originate on the shelf. This ventilation process is of fundamental importance to the physical, biological, and chemical systems in the Arctic Ocean. Little is known about where this ventilation takes place in the western Arctic, what controls its magnitude, how it occurs, or how it might vary in a changing climate. Funds are provided to better understand this ventilation process in the southern Canada Basin using a regional, high resolution ocean-ice model. The model calculations will allow for a detailed examination of the boundary - interior exchange, relate the onshore flux to specific dynamical processes and regions of the Chukchi and southern Beaufort Seas, and provide a basis for testing of theoretical constraints on this exchange. The model design, evaluation, and analysis will be closely coupled to the data being collected as part of the western Arctic Shelf-Basin Interactions program. This will provide a valuable test of the model fields, as well as motivate the model analysis to address aspects of the ventilation process that cannot be resolved with the data alone.
