South China Sea-Indonesian Seas Transport/Exchange (SITE)

该项目的重点是测量的规模和变化的南中国海（SCS）和印度尼西亚海洋运输/交换（SITE）的水质量和热通量在Karimata海峡两年使用系泊。这些数据将用作校准和验证高分辨率嵌套区域海洋模型系统的基线。这项拟议中的研究是三个国家的国际合作：美国，印度尼西亚和中国。主要目标是联合收割机在现场和数值模式，以量化的贡献，SITE流的总印尼的对流输送，从而提高我们的理解的区域和全球海洋环流和气候的变化和可预测性。虽然印度尼西亚的地下水流测量已经进行了二十多年，但在假设它没有得到观测注意的情况下，SITE流量几乎没有得到观测注意。Don’不要扮演重要角色。来自观测和数值模拟的新证据表明，SITE流在季节和年际时间尺度上都很重要，并在重塑通过马卡萨尔海峡的主要印度尼西亚洋流路径的垂直结构方面很重要。在拟议的研究中，现场和数值模型的结合将导致对以下问题的理解的重大进展：（1）现场流动及其相关热量的变化;淡水通量;（2）SITE流对印度尼西亚初级环流的影响及其对印度洋热收支、全球海洋热盐环流和气候的影响：（3）SITE流在南海环流、中尺度动力学、热量输送和海气交换中的作用;以及（4）建立一个长期替代监测系统的基础，以捕获低频印尼洋流变化。更广泛的影响：对更广泛的海洋学社区的好处将是最终允许在海洋和气候模型中忠实地模拟印度尼西亚的洋流，以增强季风，厄尔尼诺南方涛动（厄尔尼诺南方涛动）和气候预测。此外，SITE项目将促进国际合作，并将在美国、印度尼西亚和印度尼西亚提供研究和教育机会。s .中华民国。

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.
