Indian summer monsoon variability and climate-driven weathering since ∼25 ka
Vegetation dynamics, corresponding climate change and Indian Summer Monsoon variability during the Middle-to Late Holocene from the Core Monsoon Zone, India
Late Holocene geochemical and environmental changes inferred from a multiproxy investigation in sediments from Kondagai Lake Tamil Nadu, India
Climatic crises have been increasing rapidly since the late Holocene worldwide. Strategic planning needs multi-proxy records to understand the rate of ecosystem and climatic perturbations for generating mitigation maps. We present multiproxy records with isotopic composition (δ 13 C TOC , δ 15 N Bulk ), total organic carbon (TOC%), total nitrogen (TN%), total organic carbon to total nitrogen (C/N) ratio, palynofacies and grain size analysis of an…
Paleolimnology and Natural Versus Anthropogenic Influx During the Late Holocene from Vembanad Wetland, Ramsar Site, Kerala, India
A multi-proxy study of diatoms, palynofacies, and grain size was conducted on a 100 cm core from Arookutty, Vembanad wetland, Kerala, India, to reconstruct paleolimnological changes during the late Holocene, with a focus on natural versus anthropogenic influences. Four distinct depositional phases, from ca. 500 BCE to ca. 400 CE, were identified, aligning with the Roman Warm Period (RWP). The period from ca. 500 BCE to ca. 450 BCE shows high fres…
Hydroclimatic Changes Revealed by Multiple Proxies Since the Last Glacial Maximum from the Core Monsoon Zone of India
We present multiproxy records from a 2.25-m-long lake sediment profile from central India, which suggested that between ~22,200 and 18,658 cal yr BP, the Indian Summer Monsoon (ISM) was weak, supporting open vegetation in a cool and dry climate, which is globally correlated with the Last Glacial Maximum (LGM). The grain size data of this phase suggest low-energy conditions, indicating a weak ISM. Environmental magnetic concentration-dependent par…
Characterization of biotic and abiotic signatures of modern lake sediments of western India, and its palaeo-environmental implications
Was LIA synchronous with equa-tropical climate? A multiproxy study from the southwest coast of India
Presence and implications of petrogenic organic carbon in High Himalayan Crystalline lake sediment
Twelve lacustrine sediment samples from a relict lake in the Kalla Glacier valley were co-dated using AMS radiocarbon ( 14 C) and infrared stimulated luminescence (IRSL) dating methods. In general, the radiocarbon ages of bulk organic matter were older by a minimum of 1500 years compared to (age depth) modeled luminescence ages after fading corrections. This is observed for the first time in the lake sediments of High Himalayan Crystalline zone. …
Implications for catchment weathering, provenance, and climatic records from a late Pleistocene to present sedimentary sequence in Gujarat, India
To ascertain weathering, provenance, and paleoclimate of the last ca. 29 ka in mainland Gujarat, western India, a sedimentary profile of ~7.5 m was measured, described, and sampled at Pratappura and a multiproxy analysis was conducted. To determine weathering, silty-sand and sandy-silt facies were analyzed, and log Na 2 O/K 2 O versus log SiO 2 /Al 2 O 3 was plotted, which shows clustering in the quartz arenite and sub-litharenite categories, ind…
Vegetation response to the Indian Summer Monsoon (ISM) variability during the Late-Holocene from the central Indian core monsoon zone
Pollen analysis and radiocarbon dating of a 1.4 m deep lacustrine sediment profile from Chhattisgarh State, central India, in the core monsoon zone (CMZ), has revealed the vegetation history, associated climate change and the Indian Summer Monsoon (ISM) rainfall variability during the Late-Holocene. The pollen evidence suggests that between ca. 3000 and 2600 cal year BP, tree-savannah vegetation occurred in the region having a comparatively lesse…
New evidence of mid- to late- Holocene vegetation and climate change from a Neolithic settlement in western fringe of Central Ganga Plain
Here we present a continuous palaeoclimatic record of 5980 years (7230 cal BP–1250 cal BP) from Hetapatti, a Neolithic site situated on the western fringe of the Central Ganga Plain. The region was a center of reurbanisation following the decline of the Harappan civilisation and is considered a hub of economic, political and religious evolution since the sixth millennium BC. Hetapatti contains an uninterrupted sequence from Neolithic to Historic …
Variable monsoons and human adaptations
We present the first systematic evaluation of the relationship between the archaeological and palaeoclimatic record from north-western India during the past millennium, from the urban site of Chandravati. The rarity of Medieval sites, systematic excavations and multi-disciplinary work in the subcontinent obscure the impact of two distinct climate anomalies − the ‘Medieval Warm Period’ (‘MWP’, 740 − 1150 CE), followed by the ‘Little Ice Age’ (‘LIA…
Linking past cultural developments to palaeoenvironmental changes from 5000 BP to present
Floristic and climatic reconstruction in the Indo-Burma region for the last 13,000 cal. yr
The present study deals with pollen analyses from two sedimentary sequences (280 and 150 cm deep) cored from wetlands in Deepor (Kamrup district) and Hasila (Goalpara district) in the western Brahmaputra flood plain of Assam. This region is a part of the Indo-Burma region and documents changes in vegetation, climate and alterations in the wetland level as well as of anthropogenic impacts as related to the fluctuating orientation of the southwest …
