项目摘要

The goal of this project is to analyze oceanographic data from the Indonesian Through Flow (ITF) region taken during the TRIUMPH (ThRoughflow Indonesian seas, Upwelling, and Mixing PHysics) oceanographic field program, a collaboration with researchers from Indonesia and China. TRIUMPH has deployed seven moorings in the main direct ITF pathways and the upwelling region of south Java since Fall 2019. The project will examine: the full-depth of ITF transport variability and its associated heat and freshwater fluxes in the Makassar, Lombok, and Alas Straits on tidal, intraseasonal, and seasonal timescales; tidal mixing variability; and, propagation of Kelvin waves from the tropical Indian Ocean-Makassar Strait.The Indonesian Through Flow (ITF) is an essential conduit for the flow of low latitude Pacific Ocean waters into the Indian Ocean. Its variability is particularly significant because it plays a vital role in global ocean circulation and climate. Even though ITF has been measured the last three decades, no detailed measurements of full depth variability have been done nor has its impacts on mixing and upwelling along the eastern tropical Indian Ocean been investigated. This absence of data represents a significant gap in our understanding of the role of this shallow choke point in regulating the Pacific-Indian Ocean exchange, air-sea interactions, and water-mass transformation in the chokepoint of the shallow Meridional Ocean Circulation. Hence, it is essential to have detailed simultaneous measurements of the ITF, mixing, and upwelling.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目的目的是分析来自印尼语通过流动（ITF）地区的海洋数据，这是在胜利（遍布印尼海洋，上升流和混合物理学）海洋田间计划的海洋数据，这是与印度尼西亚和中国的研究人员的合作。自2019年秋季以来，Triumph已在主要直接ITF途径和South Java的上升地区部署了7个系泊设备。该项目将研究：ITF运输变异性的全深度以及其在Makassar，Lombok，Lombok和Alas海峡的潮汐，内在和季节性和季节性时代时期的Hakassar，Lombok和Alas海峡的全部及其相关的热量和淡水通量；潮汐混合变异性；而且，从热带印度洋山海峡传播开尔文波。印度尼西亚人流动（ITF）是低纬度太平洋水域流入印度洋的必不可少的渠道。它的可变性尤其重要，因为它在全球海洋循环和气候中起着至关重要的作用。即使在过去的三十年中测量了ITF，但没有对其对沿东部热带印度洋沿线的混合和上升的影响进行全面深度可变性的详细测量。缺乏数据代表了我们对这个浅扼流点在调节太平洋 - 印度海洋交换，空气相互作用和水质转换中的作用的显着差距。因此，必须详细介绍ITF，混合和上升的同时测量。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估来获得支持。
