This project focuses on measuring the magnitude and variability of the South China Sea (SCS) and Indonesian Seas transport/exchange (SITE) of the water mass and heat flux in the Karimata Strait for two years using moorings. These data will be used as baseline for calibration and validation of a high-resolution, nested Regional Ocean Model System (ROMS). The proposed research is an international collaboration of three nations: the United States, Indonesia, and China. The main goal is to combine both the in situ and numerical model to quantify a contribution of SITE flow on the total Indonesian Throughflow transport, thus enhancing our understanding of the variability and predictability of regional and global ocean circulation and climate. Although Indonesian Throughflow measurements have been conducted for more than two decades, the SITE flow has received little observational attention, under the assumption that it didn?t play an important role. New evidence from observations and numerical modeling indicates that the SITE flow is important on seasonal and inter-annual time scales, and in reshaping the vertical structure of the main Indonesian Throughflow pathway through the Makassar Strait.Intellectual Merit: The combination of in situ and numerical model in the proposed research will result in significant advances in understanding of (1) the variability of SITE flow and its associated heat-freshwater fluxes; (2) the effects of SITE flow on the primary Indonesian Throughflow and its consequence of the heat-budget to the Indian Ocean, global ocean thermohaline circulation and climate; (3) the roles of SITE flow in the SCS circulation, mesoscale dynamics, and heat transfer as well as its air-sea exchange; and (4) establishment of a basis for a long- term proxy monitoring system, as required to capture the low frequency Indonesian Throughflow variability. Broader Impacts: The benefit to the broader oceanographic community will be to finally allow the Indonesian Throughflow to be faithfully simulated within ocean and climate models to enhance the monsoon, ENSO (El Nino-Southern Oscillation) , and climate prediction. In addition, the SITE project will promote international collaborations and will offer both research and education opportunities in the United States, Indonesia, and the People?s .Republic of China.

该项目的重点是测量南中国海（SCS）和印尼海洋的传输/交换（现场）水质量和热量通量在卡里玛塔海峡使用系泊设备两年。这些数据将用作校准和验证高分辨率的嵌套区域海洋模型系统（ROMS）的基线。拟议的研究是三个国家的国际合作：美国，印度尼西亚和中国。主要目标是将原位和数值模型相结合，以量化现场流对印尼总渗透传输的贡献，从而增强我们对区域和全球海洋循环和气候的可变性和可预测性的理解。尽管已经进行了二十多年的印尼遍布测量，但在假设它没有重要作用的假设下，该地点流量很少受到观察的关注。观察结果和数值建模的新证据表明，该地点流动对于季节性和年际时间尺度以及重塑主要印度尼西亚人遍布途径的垂直结构，穿过Makassar海峡的垂直结构。拟议的研究中的模型将在理解（1）位点流及其相关的热水通量的变化方面带来重大进展； （2）现场流对印度尼西亚初级泛滥的影响及其对印度洋，全球海洋热盐循环和气候的预算的影响； （3）位点流在SC循环，中尺度动力学和传热及其空气交换中的作用； （4）建立长期代理监视系统的基础，以捕获低频印尼语贯穿流量变异性。更广泛的影响：更广泛的海洋学界的好处将是最终允许印尼在海洋和气候模型中忠实地模拟印尼人的遍布，以增强季风，ENSO（El Nino-Southern振荡）和气候预测。此外，该网站项目将促进国际合作，并将在美国，印度尼西亚和中国人民提供研究和教育机会。
