Lake sediment core data for the Mekong River Delta (Vietnam), Red River Delta (Vietnam) and Ganges Brahmaputra Delta (India and Bangladesh)

This dataset includes results obtained from lake sediments for grain-size, total inorganic/organic carbon, XRF, magnetic susceptibility, core scan imaging, sedimentary pigments, stable isotopes, radiometric dating (chronological), and site data including water chemistry at the time that sediment cores were obtained. Data is generated across multiple cores taken from each site at a differing range of depth resolutions within the sediment cores. Not all sites have had every analysis completed based on available time, core quality, and/or issues with additional funding or equipment. However, all analyses are expected to be completed within the next year or two. Bangladesh currently has the most complete dataset, followed by the Red River Delta sites and India.

本数据集涵盖湖泊沉积物的多项分析结果，包括粒度（grain-size）、总无机/有机碳、X射线荧光光谱（XRF）、磁化率、岩心扫描成像、沉积色素、稳定同位素、放射性定年（年代学），以及沉积物岩心采集时的点位水体化学数据等。数据集源自各点位采集的多根沉积物岩心，各岩心采用不同的深度分辨率开展分析工作。受可用时间、岩心质量限制，以及额外资金或设备不足等因素影响，并非所有点位都完成了全部分析项目。不过所有分析项目预计将在未来1至2年内全部完成。其中孟加拉国当前拥有最为完整的数据集，其次为红河三角洲点位与印度的相关数据。
