The Indonesian Seas are strongly influenced by the circulation system between the Pacific and the Indian Ocean, which play an important role in global circulation. In this study, an attempt is made to describe temperature, salinity, and water column stability using data obtained from the World Ocean Database (WOD), updated in 2018 at 0° latitude. The seasonal Temperature–Salinity (S-TS) were used to justify the water-mass types. The stability of the water column was analyzed based on the Brunt–Väisälä Frequency (N²). The transects were measured with depth up to 800 m and 200 km width, encompassing the Indian Ocean, Karimata Sea, Malaka Strait, Makassar Strait, Maluku Sea, Halmahera Sea, and the Pacific Ocean. Temperature and salinity profile revealed that the region in Indonesia’s eastern waters were found to have a deeper mixed layer depth ($\sim$150 m) compared to the western waters of Indonesia ($\sim$100 m). In the Pacific Ocean, the salinity layers were distinguishable compared to other layers. The T–S time diagram indicated the presence of six water-mass classes, including the water characteristic of the Pacific Ocean. It also shows that water mass from the Pacific Ocean more affects Indonesia seas in Southeast Monsoon. A relatively low salinity level distinguishes the water characteristics of the Karimata Strait compared to the other seas. In contrast, the Indian Ocean and Pacific Oceans, on the other hand, are more stable compared to other straits and seas along the equator transects (N² up to 20 cycle/h). In the Northwest Monsoon, the temperature was higher compared to Southwest Monsoon. Analysis of meridional ocean currents showed a southward pattern except for Karimata Strait, which ranges from -1.5 to 1.5 m/s. The ocean currents condition found that the most energetic meridional current flows are in the Makassar Strait and affect the distribution of temperature, salinity, and stability of surface water.

印度尼西亚海受到太平洋和印度洋之间环流系统的强烈影响，这在全球环流中起着重要作用。在这项研究中，尝试使用从世界海洋数据库（WOD）获得的数据来描述温度，盐度和水柱稳定性，该数据于2018年在0°纬度进行了更新。季节性的温度-盐度（S-TS）用于证明水质类型的合理性。根据Brunt–Väisälä频率（N ²）。测量的断面深度最大为800 m，宽度为200 km，包括印度洋，卡里马塔海，马六甲海峡，望加锡海峡，马鲁古海，哈马黑拉海和太平洋。温度和盐度分布图表明，印度尼西亚东部水域的该区域具有更深的混合层深度（$〜$150 m）与印尼西部水域（$〜$100 m）。在太平洋中，盐度层与其他层相比是可区分的。T–S时间图表明存在六个水质类，包括太平洋的水质。这也表明，来自太平洋的水团对东南季风的印度尼西亚海域的影响更大。相对较低的盐度水平使Karimata海峡的水质与其他海洋相比有所不同。相反，与沿赤道线的其他海峡和海洋相比，印度洋和太平洋更稳定（N ² 高达20个循环/小时）。在西北季风，温度高于西南季风。对子午洋流的分析表明，除了Karimata海峡外，其南移模式为-1.5至1.5 m / s。洋流条件发现，最活跃的子午流在望加锡海峡，影响温度，盐分和地表水的稳定性。
