👉 The Indonesian fluid, also known as the "Indonesian Current" or "Sunda Current," is a significant ocean current system that flows southward along the eastern coast of Indonesia and parts of Malaysia and Singapore. This warm, low-salinity current originates from the Indian Ocean and is driven by monsoon winds. It plays a crucial role in shaping Indonesia's climate, influencing weather patterns, marine ecosystems, and even the distribution of coral reefs. The Indonesian fluid interacts with the cooler, nutrient-rich waters of the Pacific, creating a dynamic and complex system that affects regional and global ocean circulation.
