Indian Ocean Monsoon plays a critical role not only in global climate but also in socio-economic conditions in the Indian subcontinent. Migration of Inter Tropical Convergence Zone (ITCZ) over the equatorial region is responsible for the occurrence of monsoons. Lying directly in the path of the ITCZ, Sri Lanka is strongly impacted by the SW (summer) and NE (winter) monsoons, which play a key role in controlling the majority of hydrological and agro-ecological differences in the island. Despite this distinctive geographical location in the ITCZ and morphological conditions, very limited number of efforts have been taken to reconstruct climate history of the island applying a palaeoclimate approach. Therefore, significant knowledge gap is present towards the understanding the evolution of atmospheric circulation pattern/monsoons of the South Asian region when moving towards the equator from higher latitudes.
In this Ph.D. project I mainly analyse various biomarkers (alkane, sterols, GDGT, LCA etc.) together with compound specific isotope analyses focusing on understanding the evolution of Indian Ocean monsoon system and related climate conditions in lower latitudes in the South Asian region and their teleconnection with other atmospheric circulation systems (eg; westerlies) during the Holocene.
