Interpretation of the Subsurface CFC Maxima in the North Pacific

9819192沃纳在这个项目中，PI将调查北太平洋温跃层的通风情况，特别是浅层地下氯氟烃（CFC）浓度最大值的来源。在世界海洋环流实验（WOCE）水文测量计划中收集的CFC数据将用于绘制这些最大值的位置，根据深度和密度，以确定该特征的空间结构。将WOCE数据与WOCE前的CFC剖面进行比较，观察CFC最大值的时间演变。除了数据分析之外，还将采用双管齐下的建模方法，从简单的平流/扩散模式开始，然后使用更复杂的环流模式来研究这一特征的起源，以及可以推断出的关于主温跃层通风的信息。

9819192WarnerIn this project, the PI will investigate ventilation in the North Pacific thermocline, specifically the origin of the shallow subsurface maxima in the concentration of Chlorofluorocarbon (CFC). The CFC data collected during the hydrographic program of the World Ocean Circulation Experiment (WOCE) will be used to map the locations of these maxima, against both depth and density in order to identify the spatial structure of this feature. WOCE data will be compared to pre-WOCE CFC sections to observe the temporal evolution of the CFC maxima. Adding to the data analysis, a two-pronged modeling approach will be employed, beginning with a simple advective/diffusive model, after which a more sophisticated general circulation model would be used to study the origin of this feature, as well as what can be inferred about the ventilation of the main thermocline.
