Indonesian Throughflow, Ocean current between Pacific and Indian Oceans, Indonesia
The Indonesian Throughflow is an ocean current that moves warm water from the Pacific Ocean to the Indian Ocean by passing through channels between Indonesian islands. The flow travels through several straits including the Makassar Strait before reaching the Indian Ocean.
Scientists studied this ocean current to understand its role in global ocean exchange and climate patterns. Research showed how the flow influences water temperatures and circulation across much of the world's oceans.
The current flows through multiple Indonesian passages, including the Makassar Strait between Borneo and Sulawesi, before entering the Bali Sea.
The current can be observed at several points between the islands when traveling by boat or from coastal areas. Water movement is most pronounced during monsoon season, making these times particularly good for observation.
The Pacific Ocean surface sits higher than the Indian Ocean, which creates the driving force for this natural system. This subtle height difference powers one of the world's most important ocean currents.
