Improving and Expanding Organic Carbon and Nitrogen Analyses at the Baruch Marine Field Laboratory

在埃里克·史密斯博士的指导下，南卡罗来纳州巴鲁克大学海洋野外实验室（BMFL）获得了一笔赠款，以支持改善和扩大其测量有机碳和氮的能力。水生环境中的有机碳和氮以溶解和颗粒形式存在，需要对每个阶段分别使用仪器。碳测量已成为广泛研究的基础，这既是因为碳是追踪食物网中物质流动的逻辑货币，也是因为人们对个体生物和生态系统在全球碳循环中所起作用的广泛兴趣。同样，测量有机态氮的分析能力越来越被认为是从捕食者-猎物动态到沿海富营养化等研究领域的关键。更广泛的影响BMFL在该地区的推广和教育方面有着出色的记录（包括广泛的努力将科学转化为非专业观众），并涉及南加州大学的许多学生。这一提议将支持继续获取各种长期时序数据。

A grant has been awarded to the University of South Carolina Baruch Marine Field Laboratory (BMFL) under the direction of Dr Eric Smith to support the improvement and expansion of their capability to measure organic carbon and nitrogen. Organic carbon and nitrogen in aquatic environments exist in both dissolved and particulate form, requiring separate instrumentation for each phase. Carbon measurements have become fundamental to a wide spectrum of research, both because carbon is a logical currency for tracing flows of materials through food webs and because of the widespread interest in the role individual organisms and ecosystems play in global carbon cycling. Similarly, the analytical ability to measure nitrogen in the organic form is increasingly recognized as critical to research areas that range from predatorprey dynamics to coastal eutrophication.Broader ImpactsBMFL has an excellent record of outreach to, and education for, the region (including an extensive effort to translate science to the lay audience), and involves many students from USC. This proposal will support the continued acquisition of various long-term time-series data.
