Dissolved Organic Carbon and Nitrogen Analysis for Coastal and Aquatic Studies.

建议购买一台台式仪器，以便高精度测量实地和实验室研究的海水样本中的溶解有机和无机碳以及总溶解氮，包括沉积物孔隙水、含盐废水和大气水(如雾水)。该仪器将是一种主要仪器，将由达尔豪西大学(至少10个不同的研究小组)和更多的研究人员使用，包括化学和生物海洋学家、海洋生态学家、大气科学家和海洋地球科学家。拟议的方法代表了海洋和大气科学中被广泛接受的“最佳实践”标准，也被广泛用于水测试实验室。然而，由于涉及额外的维护、操作和质量控制问题，Dalhousie没有可用于盐水和海水样本的此类仪器。根据以前借阅仪器的经验，该仪器将得到大量使用，并可在达尔豪西有效运行，以产生高质量的数据(如对协商一致的参考材料的分析所证明的)。除了支持研究外，鉴于这类仪器在海洋和大气研究以外的部门得到广泛使用，对学生进行的仪器培训将产生有市场价值的技能。

The proposal is to acquire a bench-top instrument that allows high-accuracy measurement of dissolved organic and inorganic carbon as well as total dissolved nitrogen on samples of seawater from the field and laboratory research including sediment pore waters, saline wastewaters and atmospheric water (e.g. fog water). The instrument will be a workhorse instrument and will be used by a wide range of investigators at Dalhousie University (at least 10 different research groups) and beyond, including chemical and biological oceanographers, marine ecologists, atmospheric scientists and marine geoscientists. The proposed methodology represents a widely-accepted, "best-practice" standard in ocean and atmospheric science and is also used widely in water-testing laboratories. However there is no such instrument at Dalhousie that is available for use with saline and seawater samples, given the extra maintenance, operating and quality-control issues involved. Based on prior experience with a loaned instrument, the instrument will be heavily used and can be operated at Dalhousie effectively in order to produce high-quality data (as evidenced by analysis of Consensus Reference Materials). In addition to supporting research, training of students on the instrument will result in marketable skills given the widespread use of this type of instrumentation in sectors other than oceanographic and atmospheric research.
