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.

这项工作将是对决定赤道太平洋温跃层结构和变化的过程的研究。 描述各种化学示踪剂分布的数据将与大气环流模式的模拟结果相结合，目的是提高模拟技术，更好地了解热带太平洋示踪剂的输送过程，并利用历史示踪剂数据识别热带上层海洋环流的变化。 模式的检验之一是模式对太平洋14C浓度的预测与热带和亚热带太平洋珊瑚14C时间序列的一致性。
