“…Most of the marine and continental records from the Arabian Sea and peninsular India demonstrated a dry climate as a result of ISM weakening (Agnihotri et al, 2002;Menzel et al, 2014). On the contrary, the wet climate has been invoked for Madhya Pradesh (Quamar and Chauhan, 2014), Gujarat (Banerji et al, 2017(Banerji et al, , 2019Sridhar et al, 2015) and central Himalayas (Kotlia et al, 2015;Sinha et al, 2015) (Figure 6). Global evidence has associated the LIA with southward migration of ITCZ (Banerji et al, 2019;Brown and Johnson, 2005;Konecky et al, 2013a;Newton et al, 2011).…”

Holocene climate variability and Indian Summer Monsoon: An overview

The response of the Indian Summer Monsoon (ISM) to forcing factors and climate variables has not yet fully explored, even though the ISM plays a pivotal role in the socio-economics of the Indian subcontinent and nearby areas. The ISM progression over Indian landmass is a manifestation of the Intertropical Convergence Zone (ITCZ) migration over the northern Indian Ocean and the Indian subcontinent. The recent anomalous behaviour of ISM raises the need for a better understanding of its spatio-temporal changes during the ongoing interglacial period termed as the Holocene period. The Holocene period has been classified further based on the globally observed abrupt climatic events at 8.2 and 4.2 ka. The 8.2 ka global cooling events have been recorded from northern Indian Ocean marine archives but limited records from the continental archives of the Indian landmass has demonstrated the 8.2 ka event. At the same time, the 4.2 ka dry climate has been endorsed by both marine as well as continental records and agrees with the global studies. During the ‘Little Ice Age’ (LIA), in the India subcontinent, wet conditions prevailed in the northern, central and western regions while a dry climate existed over the greater part of peninsular India. The present review offers an account of ISM signatures and possible mechanisms associated with the monsoon variability in the Indian subcontinent and the northern Indian Ocean during the Holocene period.

“…Studies in this regard include lake deposits of the Himalaya (Choudhary et al, 2013;Srivastava et al, 2013;Kotlia et al, 2010;Agrawal et al, 2015;Das et al, 2010), the Ganga plain (Saxena et al, 2015) and the peninsular region (Chauhan et al, 2013a;Chauhan et al, 2013b;Prasad et al, 2014;Raj et al 2015). Studies on fluvial deposits of the Narmada valley (Sridhar et al, 2015) and Cauvery delta in the peninsular region have also yielded good results. Offshore sediments from the western Bay of Bengal helped in understanding the Himalayan sediment supply during the last glacial maxima (LGM) (Tripathy et al 2014).…”

“…They have highlighted wet climate and high lake stand ~ 11,000, 7630 and between 4680 and 3500 cal year BP; winter precipitation ~ 7630 and between 4680 and 3500 cal year BP, as regional phenomena; and, decreased precipitation and dry climate between 5864-4680 and 8000-9000 cal year BP. Sridhar et al (2015) studied multi-proxy data including chronology and geochemistry of preserved sediments from the lower Narmada valley, western India. Three major environmental perturbations at 809, 1487, and 1187 cal BP have been identified, which was corroborating well with the regional fluctuations in southwest monsoon variability.…”

Sediment geochemistry is a powerful tool to investigate earth surface processes because sediments record geochemical signatures of their provenance, generation, transport, deposition, and environmental conditions. A significant advancement in the technology of analytical geochemistry has made geochemical analyses of sediments more rapid and precise, which together provided an impetus to the study of sediment system. As a result, high-quality research papers on sediment geochemistry have been published during the last five years from India. A foreseeable growth of research and an increase in the publication are likely in the future because of the new set-ups of state-of the-art analytical instruments for geochemical research at various research and academic institutions in India. Here we are presenting the published important work on sediment geochemistry under three categories, i.e., weathering, erosion, deposition and provenance determination; sediment geochemistry as palaeoclimate proxy; and environmental geochemistry.

“…These flood sediments (organic sands and silts), dated by radiocarbon method from approx. 2200-1310 BP, were accumulated in several phases of climate change related to the active impact of SW monsoon (Sridhar et al 2015). On the other place, estuaries (silts and clays laminated with sands) containing marine foraminifera (Chamyal et al 2002) were observed in a 10-meter high Holocene terrace (Tavra profile), about 10 km from the mouth of the Narmada River to the Gulf of Cambay.…”

Field trip in the semi-arid Gujarat Alluvial Plain : report

This report contains short information about the geomorphological field trip in the Gujarat Alluvial Plain. During the field trip the issues of fluvial landform and alluvial deposits of the rivers were discussed: Sabarmathi River, Mahi River, Narmada River and Karjan River. Particular attention was paid to the relief and geological structure of the Gujarat Alluvial Plain, dissected by the valleys of several rivers. The role of tectonics, sea level fluctuations and climate changes and their influence on the course of fluvial, aeolian and sea accumulation in the lower sections of river valleys was emphasized.
