Foraminiferal Analysis Related to Paleoceanographic Changes of Arafura Sea and Surrounding During Holocene
Arafura Sea is located between Papua and Australia as a part of Sahul Shelf. It is strongly influenced by ITF, ITCZ replacement, monsoon, and ENSO circulation that interplay with local mechanism. To understand the paleoceanographic parameter changes during Holocene, we conducted foraminiferal quanti...
