A multi-proxy lake sediment record of Indian summer monsoon variability during the Holocene in southern India

Abstract: We present here a 11,000-year palaeomonsoonal record from a sediment core (SS-1) from Shantisagara (SS) Lake in Peninsular India, which is the longest published so far from the region. This is also a region with limited palaeoclimate records. Environmental magnetic, organic geochemical, sedimentological and carbon isotopic studies were carried out on the SS-1 sediments to reconstruct the Indian summer monsoon (ISM) variability during the Holocene. The chronology of the sediments is constrained by three AMS 14 … Show more

“…Sedimentary basins such as lakes are closely connected with their surrounding environments especially the catchment areas, making them as sensitive recorders of perturbations within their catchment watersheds (O'Beirne et al, 2015). Lake sediments provide direct evidence of the past environmental changes on the local and/or regional scale, with a relatively high, millennial to centennial resolution (Mills et al, 2014;Plater et al, 2006;Sandeep et al, 2017). Elemental geochemistry of lake core sediments provides a principal tool for reconstructing the paleoenvironmental and paleoclimate changes that have occurred during the Holocene period (Jiang et al, 2007;Li et al, 2016Li et al, , 2017Lone et al, 2018c;Sadori et al, 2016).…”

“…The first global cooling event recorded during the Holocene epoch is marked by fluctuation in the North Atlantic deepwater circulation and northward movement of heat due to the mixing of meltwater from Laurentide ice sheets (Hong et al, 2003;Walker et al, 2012;Marzin et al, 2013;Menzel et al, 2014). Considering dating uncertainty, this event has been reported in several terrestrial (Anoop et al, 2013b;Walker et al, 2012;Dixit et al, 2014;Rawat et al, 2015;Sandeep et al, 2017) as well as marine archives (Gupta et al, 2003;Govil and Naidu, 2011;Rashid et al, 2011). However, no major focused studies have yet been done in India to explicitly link 8.2 ka event with specific cultural adaptations/changes, though this is a time when the Neolithic lifestyle is well-established in some regions and just beginning to appear in other regions of the subcontinent (Figure 1).…”
