The University of Southern Mississippi Center for Marine Science (CMS) is a relatively young organization (less than four years old); however, in its short existence, it has been very successful in establishing a quality research program focussed on chemical and biological oceanography. Of central importance in such work is the ability to follow trace elements in the environment. Trace elements (such as the metals copper and zinc) can be nutrients and/or toxins, but some of the previous work with such elements is now suspect because of the failure of previous workers to follow presently accepted clean laboratory protocols. For example, many determinations of oceanic primary production may be unreliable due to trace-element contamination. This project will provide funds to construct and equip a state-of-the-art trace-element facility at CMS. It will encompass preparatory and culture laboratories as well as items of specialized analytical equipment, including a nutrient analyzer, a high-speed centrifuge, and a spectrophotometer. The laboratory will be maintained scrupulously clean, and the most stringent protocols will be followed in order to insure the integrity of trace-element research in it. The facility will allow on-site and visiting researchers to continue and expand their involvement in such activities as NSF's Global Ocean Flux Study. Equally important, the facility will be located close to important coastal wetlands and will have direct access to the Gulf of Mexico.

南密西西比大学海洋科学中心(CMS)是一个相对年轻的组织(成立不到四年)；然而，在其短暂的存在期间，它在建立专注于化学和生物海洋学的高质量研究计划方面取得了非常成功的成就。在这类工作中，最重要的是能够跟踪环境中的痕量元素。微量元素(如金属铜和锌)可以是营养素和/或毒素，但以前对这些元素的一些工作现在受到怀疑，因为以前的工作人员没有遵循目前公认的清洁实验室方案。例如，由于微量元素污染，许多海洋初级生产力的测定可能不可靠。该项目将提供资金，在CMS建造和装备最先进的痕量元素设施。它将包括预备和培养实验室以及专门的分析设备，包括营养分析仪、高速离心机和分光光度计。实验室将一丝不苟地保持清洁，并将遵循最严格的规程，以确保其中微量元素研究的完整性。该设施将允许现场和访问研究人员继续并扩大他们对NSF全球海洋通量研究等活动的参与。同样重要的是，该设施将位于重要的沿海湿地附近，并将直接通往墨西哥湾。
