Development of a Simple Technique to Analyze Rare Earth Elements in Pore Fluids to Investigate the Potential Cycling of REE in Near-Surface Sediments

这是一个建议，开发一种方法来分析小样(1-4毫升)沉积物孔隙水中的稀土元素，使用一种新的高分辨率ICPMS仪器。这项技术如果成功，将有助于从根本上了解稀土元素在沉积物中的行为，这是一个重要的目标。此外，利用斯克里普斯提供的船期，PI将从加州边界地区收集沉积物岩心，那里表层沉积物的氧化还原状态存在很大差异。因此，岩心孔隙水的分析将有助于研究不同氧化还原条件下沉积物孔隙水中稀土元素(REE)的化学行为

This is a proposal to develop a method to analyze the rare earth elements in small samples (1-4 ml) of sediment pore water, using a new high resolution ICPMS instrument available at SIO. The technique, if successful, will help in fundamental understanding of the behavior of REE in sediments, an important goal. In addition, with shiptime provided by Scripps, the PI will collect sediment cores from the California borderlands, where there exist large differences in the redox state of surface sediments. Analysis of pore waters in these cores will thus be useful for investigating the chemical behavior of the rare earth elements (REE) in sediment pore waters under different redox conditions
