Collaborative Research: SAFe: Completing the Last Part

在本研究中，Moss Landing海洋实验室的一名研究人员将与加州大学圣克鲁兹分校的一名科学家合作，完成在美国国家科学基金会资助的Fe采样和分析（SAFe）项目中收集的海岸表面样品（C1）的装瓶。这个样本是在SAFe项目期间唯一一个从沿海水域获得的样本，它的铁浓度和铁络合有机物的含量都高于其他三个样本。因此，这个示例对于方法开发和作为参考材料将非常有用。此外，将对C1进行分析，以确保其随时间的稳定性和同质性，并提供给海洋科学界。在长期储存过程中，之前收集的SAFe表面样品（S1）和深水样品（D1和D2）也将继续定期检查稳定性和均匀性。关于这四种标准物质的稳定性和均匀性的所有结果将提供给社会。至于更广泛的影响，这项工作将使参与痕量金属分析的全球科学界能够获得海水铁的第四种参考物质，从而确保进行高质量的铁测量。此外，这些样品还可以为各种微量元素提供未受污染的典型海水值，这是GEOTRACES等程序中分析人员的宝贵资源。

ABSTRACTOCE-0622845OCE-0622838In this study, a researcher at Moss Landing Marine Laboratories will collaborate with a scientist at the University of California, Santa Cruz, to complete the bottling of the coastal surface sample (C1) collected during the NSF funded Sampling and Analysis of Fe (SAFe) program. This sample is the only one obtained during the SAFe program from coastal waters with higher concentrations of iron and higher amounts of iron-complexing organic matter than the other three. Thus, this sample will be very useful for method development and as a reference material. In addition, C1 will be analyzed to ensure its stability and homogeneity over time, and be made available to the marine science community. The previously collected SAFe surface sample (S1) and deep-water samples (D1 and D2) will also continue to be periodically checked for stability and homogeneity during the long-term storage process. All results on the stability and homogeneity of these four reference materials will be provided to the community. As regards broader impacts, this work will make available to the worldwide science community involved in trace metal analysis, a fourth reference material for seawater iron, thereby ensuring that high quality iron measurements are made. Also, these samples have the benefit of providing uncontaminated typical seawater values for a variety of trace elements, an invaluable resource to analysts in programs such as GEOTRACES.
