9700004 Noakes This grant provides funds for the purchase of a multi- dispersive x-ray fluorescence (XRF) spectrometer that will be incorporated into a CAIS-designed shipboard system for rapid data collection, analysis, and mapping in aquatic environments. The Continuous Sediment Sampling and Analysis System, or CS, uses a submersible pump mounted on a towed sled to deliver a continuous stream of surface sediments to a shipboard processor. Samples can be immediately analyzed for elemental constituents using XRF spectroscopy. The multi-dispersive instrument incorporates both wavelength- dispersive and energy-dispersive systems in one unit, providing superior analytical results for sediment elemental constituents by improving reliability and reducing the minimum detection levels that can be measured. ***

这笔拨款用于购买一台多色散x射线荧光（XRF）光谱仪，该光谱仪将被集成到cais设计的船载系统中，用于在水生环境中快速收集、分析和绘制数据。连续沉积物采样和分析系统（CS）使用一个安装在拖曳雪橇上的潜水泵，将连续的地表沉积物流输送到船上的处理器。样品可以立即分析元素成分使用XRF光谱。多色散仪器将波长色散和能量色散系统集成在一个单元中，通过提高可靠性和降低可测量的最低检测水平，为沉积物元素成分提供卓越的分析结果。＊＊＊
