Hydroclimate Variability in the Mainland Southeast Asia During the Last Glacial Maximum
The Last Glacial Maximum (LGM) is a key reference point for understanding past climate, but its complexity can lead to ambiguities in scope and interpretation. In this study, we applied a suite of geochemical techniques -XRF, grain size, and pollen analysis- to a well-dated sedimentary sequence from the lower central plain of Thailand. Our results show a gradual increase in fluvial runoff and precipitation from 26.5 to 24.6 cal ka BP, followed by…
Enso may have contributed to sea level changes in the Gulf of Thailand during the Late-Holocene
The Gulf of Thailand is ideal for studying eustatic sea level fluctuations in Southeast Asia due to its shallow basin and tectonic stability. However, our understanding of how this region’s relative sea level (RSL) has fluctuated over the Holocene epoch is far from complete. In this study, we used lithostratigraphy, loss on ignition, grain size, and pollen analyses to reconstruct the environmental changes in the Sam Roi Yot wetland, which was sig…
East Asian winter monsoon variation during the last 3000 years as recorded in a subtropical mountain lake, northeastern Taiwan
The East Asian Winter Monsoon (EAWM) is a fundamental part of the global monsoon system that affects nearly one-quarter of the world’s population. Robust paleoclimate reconstructions in East Asia are complicated by multiple sources of precipitation. These sources, such as the EAWM and typhoons, need to be disentangled in order to understand the dominant source of precipitation influencing the past and current climate. Taiwan, situated within the …
Societal response to monsoonal fluctuations in NE Thailand during the demise of Angkor Civilisation
This paper investigates the possible social responses to changes in the strength of the southwest monsoon in northeastern Thailand during the currency of the Angkor civilisation. These assessments are based on hydrogen and carbon isotope records of leaf waxes (δD wax and δ 13 C wax ) from a 2000-year-long wetland sequence of Pa Kho in northeastern Thailand, a region that formed the northern boundary of the Angkor Kingdom. Our data indicate anthro…
Human adaptation to mid- to late-Holocene climate change in Northeast Thailand
This article integrates palaeoenvironmental and archaeological sequences covering the mid- to late-Holocene in Northeast Thailand. The former reveal the fluctuating intensity of the Asian summer monsoon, leading to periods of higher moisture availability with intervals of relative aridity. The latter are founded on a series of new radiocarbon determinations that provide a basic chronological framework, from the initial Neolithic settlements by ri…
Lake Kumphawapi revisited – The complex climatic and environmental record of a tropical wetland in NE Thailand
Kumphawapi, which is Thailand’s largest natural freshwater lake, contains a >10,000-year-long climatic and environmental archive. New data sets (stratigraphy, chronology, hydrogen isotopes, plant macrofossil and charcoal records) for two sedimentary sequences are here combined with earlier multi-proxy studies to provide a comprehensive reconstruction of past climatic and environmental changes for Northeast Thailand. Gradually higher moisture avai…
