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

这是一个建议，开发一种方法来分析小样品（1-4毫升）的沉积物孔隙水的稀土元素，使用一个新的高分辨率ICPMS仪器可在SIO。这项技术如果成功，将有助于从根本上了解沉积物中稀土元素的行为，这是一个重要的目标。此外，利用Scripps提供的船期，PI将从加州边境地区收集沉积物岩心，那里的表层沉积物氧化还原状态存在很大差异。因此，对这些岩心孔隙沃茨的分析将有助于研究不同氧化还原条件下沉积物孔隙沃茨中稀土元素的化学行为
