Further WorkFurther Work

“INSTANT is an ambitious collaboration of 5 nations (Australia, France, Indonesia, Netherlands and the USA), which is designed to provide a time series of Indonesian throughflow transport and property fluxes, and their variability from intraseasonal to annual time scales, from the intake of Pacific water at Makassar Strait and Lifamatola Passage, to the Lesser Sunda exit channels into the Indian Ocean.”
