This award provides funds to purchase a Stable Isotope Ratio Mass spectrometer system at the Skidaway Institute of Oceanography (SkIO). Such instruments are workhorse devices in the Marine science and Ecology fields, as they provide data crucial to understanding such subjects as food webs, nutrient and carbon sources, and carbon cycling. This new instrumentation has significantly lower sample size requirements than the equipment it is replacing, and allows for new measurements of sulfur isotopes at our facility. Together these improvements will allow scientists and students at SkIO to conduct research at finer spatial and temporal resolutions. The new instrument is also ideal for training students, both undergraduate and graduate, in stable isotope analyses by conducting hands on experiments and analyzing their data in rapid fashion. SkIO’s stable isotope facility is a regional hub for such analyses, and while normal practice is to charge users to recover costs for expendables, 10% of the funds accrued in this manner will be used to provide no-cost analyses and data interpretation to undergraduate institutions and regional groups. In this manner a broader range of students will gain direct experience in this field and in ecological marine science studies in general.This project provides funds to purchase a Thermo Delta Q Light Stable isotope Mass Spectrometer capable of Carbon, Nitrogen, Oxygen and Sulfur Isotope measurements. Two sample processing interfaces, a LC-Isolink II and an elemental analyzer (EA) with Nano-EA modifications, replace older and non-supported interfaces. The new LC interface will be used to support ongoing and future studies in dissolved organic matter cycling and composition as well as oceanic carbon cycling. The new EA will provide for new research directions, including food web studies using individual micro-zooplankton measurements and compound-specific analyses on HPLC isolates. The facility provides rapid-response measurements to a user base primarily conducting research along the Georgia coast and has also provided services to scientists and students from South America and Europe. The semi-automated nature of the new instruments allows for excellent opportunities for student training and research, therefore funds and instrument time have been set aside for access by underserved groups and institutions. This award by the Division of Biological Infrastructure is supported by the Directorate for Geosciences, Division of Ocean Sciences.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项提供资金在斯基德威海洋学研究所 (SkIO) 购买稳定同位素比质谱仪系统，此类仪器是海洋科学和生态学领域的主力设备，因为它们提供对理解食物网、营养物等学科至关重要的数据。与它所取代的设备相比，这种新仪器的样品量要求显着降低，并且允许在我们的设施中进行硫同位素的新测量。该新仪器也非常适合培训本科生和研究生通过进行实际实验并快速分析数据来进行稳定同位素分析。此类分析的区域中心，虽然通常的做法是向用户收费以收回消耗品的成本，但以这种方式累积的资金的 10% 将用于向本科机构和区域提供免费分析和数据解释通过这种方式，更广泛的学生将获得该领域和一般生态海洋科学研究的直接经验。该项目提供资金购买能够检测碳、氮、氧和硫的 Thermo Delta Q 光稳定同位素质谱仪。同位素测量。两个样品处理接口，一个 LC-Isolink II 和一个经过 Nano-EA 修改的元素分析仪 (EA)，取代旧的和不支持的接口。新的 LC 接口将用于支持。正在进行和未来的溶解有机物循环和组成以及海洋碳循环研究将提供新的研究方向，包括使用单个微型浮游动物测量和对 HPLC 分离物进行化合物特异性分析的食物网研究。向主要在乔治亚州海岸进行研究的用户群进行快速响应测量，并为来自南美和欧洲的科学家和学生提供服务。因此，新仪器的半自动化特性为学生培训和研究提供了绝佳的机会。资金和工具时间已预留给服务不足的团体和机构。该奖项由生物基础设施司得到地球科学局、海洋科学司的支持。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准。
