As part of global ocean circulation, warm water in the upper layer flows from the Pacific Ocean to the Indian Ocean through the Indonesian Archipelago. The flow through the archipelago, known as the Indonesian Throughflow, is neither a steady one nor a single stream as it navigates through the various seas, straits and passages. A team of researchers published a study that investigated the role eddies play in determining the path and transit times through this major sea area—dynamics that ultimately influence the climate of the region.
