项目摘要

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.

建议是购置一台台式仪器，以便能够高精度地测量来自实地和实验室研究的海水样本，包括沉积物孔隙沃茨、含盐废水沃茨和大气水（例如，雾水）中的溶解有机碳和无机碳以及总溶解氮。该仪器将是一个主力仪器，将由达尔豪西大学（至少10个不同的研究小组）和其他大学的广泛研究人员使用，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。拟议的方法是海洋和大气科学中被广泛接受的“最佳做法”标准，也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，达尔豪西没有这样的仪器可用于盐水和海水样品。根据之前使用租借仪器的经验，该仪器将被大量使用，并可在达尔豪西有效操作，以产生高质量数据（通过共识参考材料的分析证明）。除了支持研究外，对学生进行仪器培训将使他们掌握适销对路的技能，因为这类仪器广泛用于海洋学和大气研究以外的其他部门。
