Observations and Dynamics of the Indonesian Throughflow

Sprintall/HautalaFunds提供了一个简单的，减少重力数值模型，以阐明动态作用于季节到年度的时间尺度上的印度尼西亚通流的观测进行了广泛的分析。观测数据集包括浅层压力计网络、正在进行的ADCP和CTD表面测量、海流计系泊、水文和XBT剖面、风数据和海面测高。主要的科学问题是：（1）什么是通流的平均值和变率;（2）是什么过程引起的变化，每年，半年，和季节内的时间尺度;（3）什么是这种变化的影响，对热量和盐输送;（4）南爪哇海流如何改变流域的水团结构;（5）与1997-1998年厄尔尼诺事件有关的变化是什么。

Sprintall/HautalaFunds are provided to conduct an extensive analysis of observations of the Indonesian throughflow in conjunction with a simple, reduced gravity numerical model to elucidate the dynamics acting on seasonal to annual time scales. The observational data set consist a network of shallow pressure gauges, underway ADCP and CTD surface measurements, a current meter mooring, hydrographic and XBT sections, wind data and sea surface altimetry. The main scientific question that will be addressed are: (1) what are the mean and variability of the throughflow; (2) what are the processes that cause variability on annual, semi-annual, and intraseasonal time scales; (3) what is the impact of this variability on heat and salt transports; (4) how does the South Java Current alter the water mass structure in the basin, and (5) what are the changes associated with the 1997-1998 El Nino event.
