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与海洋联合研究所的 Joseph Resing 博士和佛罗里达州立大学的 William Landing 博士提出了一项雄心勃勃的实地研究，在 CLIVAR/ 上进行痕量金属采样2013 年在大西洋重复 CO2 水文剖面 A16N。该现场计划将提供一个宝贵的机会来阐明气溶胶-水柱耦合以及选定痕量金属（Fe、Al 和其他）和生物碳酸钙。除了研究有关水柱中微量元素分布对外部灰尘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进行比较，进一步深入了解微量金属分布的时间和空间变化问题，最引人注目的是国际 GEOTRACES 计划。 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项国内和国际合作，为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。
