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.

This field program will provide a valuable opportunity to elucidate aerosol-water column coupling, and possible decadal对于选定的痕量金属（Fe，Al等）和碳酸盐钙的变异性。除了检查有关水柱中痕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Invetigators还将通过与其他现场计划进行比较（最著名的是国际地质计划计划），进一步了解痕量金属分布中时间和空间变化的问题。 关于这项研究的更广泛意义，这次大型探险的结果将产生多次国家和国际合作，为研究生和博士后研究员的教育和培训做出了积极贡献，并引起了海洋科学社区的广泛兴趣。
