Operation of a National Ocean Sciences Accelerator Mass Spectrometry Facility of the Woods Hole Oceanographic Institution

9807266 Hayes该奖项授予马萨诸塞州的伍兹霍尔海洋研究所，为国家海洋科学加速器质谱仪设施的运行提供支持。 该设施进行碳同位素分析，特别是14-C，用于海洋、地球和大气科学研究。该奖项最初三年的分析工作的一个主要组成部分预计将是作为世界海洋环流实验（WOCE）的一部分收集的水样，这是一项了解世界海洋环流和结构的国际计划。 除了WOCE样品外，该设施还研究对非常小的样品（最小为25微克碳，而AMS标准样品为300微克）和特定化合物样品进行定量分析的技术，从而可以研究样品的单个成分，从而提高对地球化学过程的理解。 它还为地球和海洋科学界提供放射性碳测年和碳同位素研究设施。 本奖项的主要重点是改善样品周转时间，升级基于网络的信息和样品提交程序，减少维护时间，改善系统监控，提高样品吞吐量，同时保持高分析精度，并在不增加人员配备的情况下增加每年分析的样品总数。该奖项通过合作协议提供五年的支持，并计划在第三年进行绩效审查。 ***

9807266 Hayes This award to Woods Hole Oceanographic Institution in Massachusetts provides support for operation of the National Ocean Sciences Accelerator Mass Spectrometer facility. This facility carries out analyses of carbon isotopes, particularly 14-C, for research in ocean, earth and atmospheric sciences. A major component of the analytical work during the initial three years of the award is expected to be water samples collected as part of the World Ocean Circulation Experiment (WOCE), an international program to understand the circulation and structure of the world oceans. In addition to WOCE samples, the facility carries out research in techniques for quantitative analysis of very small samples (to a minimum of 25 micrograms carbon, compared to standard AMS sample size of 300 micrograms) and compound-specific samples, which allows study of individual components of samples, and hence improved understanding of biogeochemical processes. It also provides a facility for radiocarbon dating and study of carbon isotopes for the earth and ocean sciences community. Major emphasis in the present award focuses on improving sample turnaround time, upgrading web-based information and sample submittal procedures, reducing maintenance time, improving system monitoring, improving sample throughput while maintaining high analytical precision, and increasing the total number of samples analyzed annually without increasing staffing levels. This award provides support for five years via a cooperative agreement, with a review of performance planned during the third year. ***
