Data from: Makassar Strait Throughflow Seasonal and Interannual Variability: An Overview

This inter-ocean exchange is known as the Indonesian Throughflow (ITF). The ITF affects heat and freshwater balances of the Pacific and Indian Oceans.

The primary inflow path of Pacific water into the Indonesian Seas is the Makassar Strait between Kalimantan and Sulawesi. During the 21 years from November 1996 to August 2017, we recorded 13.3 years of Makassar throughflow, exposing a broad range of spatial and temporal patterns. The Makassar Strait average transport is 12.5 million cubic meters per second, about 77% of the total ITF flow, with the annual cycle transport ranging from 7 to 16 million cubic meters per second.
