Timing and Pacing of Indonesian Throughflow Restriction and Its Connection to Late Pliocene Climate Shifts Open
The Pliocene was characterized by a gradual shift of global climate toward cooler and drier conditions. This shift fundamentally reorganized Earth's climate from the Miocene state toward conditions similar to the present. During the Plioce…

Future changes to the Indonesian Throughflow and Pacific circulation: The differing role of wind and deep circulation changes Open
Climate models consistently project a substantial decrease in the Indonesian Throughflow (ITF) in response to enhanced greenhouse warming. On interannual timescales ITF changes are largely related to tropical Pacific wind variability. Howe…
