Collaborative Research: Shallow Circulation in the Tropical Pacific: A Geochemical and Modeling Study

这项工作将研究决定赤道太平洋温跃层结构和可变性的过程。描述各种化学示踪剂分布的数据将与用大气环流模式进行的模拟进行比较，目的是提高模拟技能，更好地了解热带太平洋中输送示踪剂的过程，并利用历史示踪剂数据来识别热带上层海洋环流的变化。该模型的检验之一将是将该模型对太平洋14C浓度的预测与热带和亚热带太平洋珊瑚的14C时间序列进行比较。

This work will be a study of processes that determine the structureand variability of the thermocline in the equatorial Pacific. Datadescribing the distribution of various chemical tracers will becompared with simulations made with a general circulation model.The aim is to improve modeling skill, gain a better understanding ofthe processes that transport tracers in the tropical Pacific, and touse the historical tracer data to identify variations in the tropicalupper-ocean circulation. One of the tests of the model will be acomparison between the model's prediction of 14C concentration inthe Pacific with 14C time series derived from corals in the tropicaland subtropical Pacific.
