Dr. Joseph Resing of the Joint Institute for the Study of the Atmosphere and the Ocean, Pacific Marine Environmental Laboratory, University of Washington and Dr. William Landing of Florida State University have proposed an ambitous field study to conduct trace metal sampling on the CLIVAR/CO2 Repeat Hydrography section A16N in the Atlantic Ocean in 2013. This field program will provide a valuable opportunity to elucidate aerosol-water column coupling, and possible decadal variability, for selected trace metals (Fe, Al, and others) and biogenic calcium carbonate. In addition to examining important questions regarding the nature of the response of trace element distributions in the water column to external dust input, these invetigators will gain further insight into the issue of temporal and spatial changes in trace metal distributions through comparison with other field programs, most notably the international GEOTRACES program. With regard to the broader significance of this study, results from this large expedition will generate multiple national and international collaborations, contribute positively to the education and training of a graduate student and a postdoctoral fellow, and be of broad interest to the ocean sciences community.

大气与海洋联合研究所、太平洋海洋环境实验室、华盛顿大学的Joseph Resing博士和佛罗里达州立大学的William Landing博士提出了一项雄心勃勃的实地研究，即在2013年对大西洋CLIVAR/CO2重复水文剖面A16N进行痕量金属取样。这个实地项目将为阐明选定的微量金属（铁、铝等）和生物源碳酸钙的气溶胶-水柱耦合和可能的年代际变化提供宝贵的机会。除了研究水柱中微量元素分布对外部尘埃输入的响应性质的重要问题外，这些研究人员还将通过与其他现场项目（最著名的是国际GEOTRACES项目）的比较，进一步了解微量金属分布的时空变化问题。就这项研究的更广泛意义而言，这次大型考察的结果将产生多个国家和国际合作，对研究生和博士后的教育和培训做出积极贡献，并引起海洋科学界的广泛兴趣。
