|dc.description.abstract||The Asian monsoon is a complex and dynamic system and a significant driver of hydrological change in the global climate system. A number of monsoon subsystems, distributed over various geographical areas, make up the larger Asian monsoon system. The dynamics of climate change in the Asian monsoon over the Holocene in these subsystems is of key interest, given that the instrumental record is short and geographically biased and there is a low density of palaeoclimate records of sufficient length and resolution to capture long-term broader scale change and variability.
The response of the Asian monsoon over mainland Southeast Asia is an important yet little studied aspect of the monsoon system. This region is of interest due to its location on the cusp of the Indian monsoon and East Asian monsoon subsystems. Gaining a better understanding of broad scale events in the Holocene as experienced by this region can assist in clarifying whether climatic responses in the various geographical provinces of the Asian monsoon occur asynchronously or in concert. This deepens the understanding of the geographical behaviour of the monsoon in relation to teleconnections and forcing mechanisms.
This study provides a high resolution independently dated record of climate variability from the early Holocene, from stable isotopes from authigenic carbonates held in lake sediment archives. It presents new insights into the timing of the onset of dryer conditions in this region following the Holocene Optimum, which will herald valuable insight into the climate dynamics and teleconnections in the tropics in the recent past.||en_AU|
