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.

鉴于全球变暖和海平面上升，重要的是要了解海岸沉积系统，其各种过程作用于不同的时间尺度，空间维度，并具有不同的效果。泰国湾位于中国南海大陆架上，是一个经济重要和人口密集的地区。本提案是与来自曼谷的同事密切合作在泰国湾东部开展的先前工作的继续。该项目的目的是帮助重建该地区的海岸演变。这是通过查明过去海平面变化、海岸线运动的证据和破译Chantaburi和Welu河口之间地区沉积物积累的作用来实现的。这将通过地貌测绘、地球物理测量和在选定地点钻取沉积物岩心相结合的方法来完成。后者将被用来重建沉积相和石英的光激发光信号，并可能放射性碳，将被用来把沉积物沉积到一个时间框架。
