We present our work on a total of 1368 sediment samples spanning the past ~3.17-1.07 Ma from Site U1482 (15°3.32ʹS, 120°26.10ʹE, water depth of 1466m), which was drilled during the International Ocean Discovery Program Expedition 363 in the Timor Passage, the main exit of the Indonesian Throughflow to the Indian Ocean. We established the first high-resolution (~1.53 kyr) Plio-Pleistocene benthic δ18O stratigraphy based on Planulina wuellerstorfi during ~3.17-1.07 Ma, and present benthic δ13C as well.
