Holocene coastal dynamics in the eastern Gulf of Thailand

鉴于全球变暖和海平面上升，重要的是了解沿海沉积系统及其作用于不同时间尺度、空间维度和不同影响的各种过程。泰国湾位于南中国海的大陆架上，是重要的经济和人口稠密地区。本提案是与曼谷同事密切合作在泰国湾东部开展的先前工作的继续。该项目的目的是促进该区域沿海演变的重建。这是通过确定过去海平面变化、海岸线运动的证据和破译昌塔布里和韦卢河口之间地区沉积物堆积的作用来实现的。这将通过地貌测绘、地球物理测量和从选定地点钻探沉积物岩心的组合来完成。后者将用于重建沉积相和石英的光激发发光信号，潜在的放射性碳将用于将沉积物沉积置于年代学框架中。

In the light of global warming and rising sea level, it is important to understand coastal sedimentary systems with their variety of processes acting on different timescales, spatial dimensions, and with different effects. The Gulf of Thailand is located on the continental shelf of the South China Sea and is an economically important and densely populated area. The present proposal represents a continuation of previous work in the eastern Gulf of Thailand that was done in close collaboration with colleagues from Bangkok. The aim of the project is to contribute to the reconstruction of the coastal evolution in the region. This is done by identifying evidence of past sea-level change, coastline movements and deciphering the role of sediment accumulation in the area between the Chantaburi and Welu estuaries. This will be done using a combination of geomorphological mapping, geophysical surveying, and drilling sediment cores from selected sites. The latter will be used to reconstruct sedimentary facies and optically stimulated luminescence signal of quartz, and potentially radiocarbon, will be used to place sediment deposition into a chronological frame.
