“…Interpretation of the Arabian Sea core data for the last 3 million years (Ma) revealed ~400 ka cyclicity in Earth's eccentricity that influenced the Quaternary Aeolian Landscape Development in Thar Desert and Its Drivers 407 monsoon variability and aeolian dust deposition. Very weak monsoon and high dust deposition were recoded at the transition from the Pliocene to the Pleistocene (~2.6 Ma), and then at several time periods during the Pleistocene, the last notable increase being ~1.5 thousand years (ka) before present (Clemens and Prell, 1991Prell, , 2003Pandey et al, 2016;Albani et al, 2018;Wang et al, 2019). The deciphered periods of weaker monsoon in the cores generally implied a reduced strength of the SW monsoon wind over the Thar Desert, but the higher dust concentrations were most likely due to strong westerly wind-driven supplies from the Middle East sources, rather than from the Thar Desert.…”

Research on the aeolian processes and landforms in the Thar Desert is not a very fertile academic field in India, especially because of the region's locational and climatic disadvantages. Studies by some dedicated groups over the past few decades helped to improve our understanding of the present-day process-form interactions in the desert. Linking those understanding with the results from optically stimulated luminescence dating of the sediments a broad framework of landscape development history during the late Quaternary period has been developed. The studies so far confirm that climate, especially its oscillations between warm wet and dry cool phases in an overall monsoon domain, was the most dominant driver of landscape development in our desert, and that the aeolian processes became more efficient during the transition from a drier to a wetter phase, rather than during the peak of dry period. There were, however, some notable exceptions to that rule. We highlight some of the unresolved issues, and discuss how analysis of the results from climate simulation modelling, understanding of the complementarities between aeolian and fluvial processes under different spatio-temporal contexts, and interpretation of the satellite sensor-based and ground-based observations of the modern processes can help to strengthen our knowledge on aeolian landscape development in the region.

“…From 2013 to 2016, Integrated Ocean Drilling Program/International Ocean Discovery Program (IODP) conducted a series of expeditions that were focused on AM evolution and its interaction with the wider climate system in the NW Pacific and Indian Ocean regions. In this volume of SPEPS, we introduce some of the new results concerning the evolution and variability of the AM during the Neogene obtained from IODP Expeditions 346, 355, and 359 (Tada et al 2015;Pandey et al 2016;Betzler et al 2017). AM evolution on tectonic time scales is the major topic of this SPEPS.…”
