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.

华盛顿大学太平洋海洋环境实验室大气和海洋联合研究所的Joseph Resing博士和佛罗里达州立大学的William Landing博士提议进行一项不定期的实地研究，以便于2013年在大西洋CLIVAR/CO2 Repeat水文剖面A16 N进行痕量金属采样。 这一领域的计划将提供一个宝贵的机会，阐明气溶胶-水柱耦合，可能的十年变化，为选定的微量金属（铁，铝等）和生物碳酸钙。除了检查重要的问题，在水柱中的微量元素分布的响应的性质，外部灰尘输入，这些inventidators将获得进一步深入了解的时间和空间变化的问题，通过与其他领域的计划，最显着的国际GEOTRACES计划比较，在微量金属分布。 关于这项研究的更广泛意义，这次大型考察的结果将产生多个国家和国际合作，为一名研究生和一名博士后研究员的教育和培训作出积极贡献，并引起海洋科学界的广泛兴趣。
