| Scope | Although Asian Monsoon (AM) is a regional phenomenon, it exerts a significant impact on the global climate. Since uplift of Himalaya and Tibetan Plateau (HTP) has been considered to have played a significant role on the establishment and intensification of AM, numerous attempts have been made to prove the linkage between the HTP uplift and AM evolution, but the linkage is largely unproved till now. On the other hand, comparison of global climatic changes, pCO2 reconstructions, and AM evolution process during Cenozoic suggests that AM evolution is significantly affected by global climate changes most likely through pCO2. Thus, importance of the HTP uplift on AM evolution is questioned. However, it should be noted that the effects of the HTP uplift and AM precipitation on chemical weathering, erosion, and CO2 uptake could be acting as feedback loops on AM-HTP uplift linkage. From July 2013 to November 2016, IODP conducted a series of expeditions such as 346 (Asian Monsoon), 353 (Indian Monsoon Rainfall), 354 (Bengal Fan), 355 (Arabian Monsoon), 356 (Indian through-flow), and 359 (Maldives Monsoon) that are related to AM evolution and its interaction with global climate system in NW Pacific and Indian Ocean regions, and exciting results are gradually coming out. We believe it is timely to start gathering and synthesizing the results of these cruises and update and exchange information and ideas to promote our understanding of AM evolution, variability, their controlling factors, and their interaction with global climate system during the Cenozoic. | |
