Collaborative Research: Trace Metal Deposition And Cycling In The North Atlantic On The 2013 CLIVAR/Repeat Hydrography A16N Expedition

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博士提议进行一项大规模的实地研究，以于2013年在大西洋CLIVAR/CO2重复水文剖面A16N进行痕量金属采样。这一实地研究计划将为阐明特定微量金属(铁、铝和其他)和生物碳酸钙的气溶胶-水柱耦合以及可能的年代际变化提供宝贵的机会。除了研究有关水体中痕量元素分布对外部粉尘输入的响应的性质的重要问题外，这些调查者还将通过与其他实地计划(最著名的是国际地质勘测计划)的比较，进一步深入了解痕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，这一大型考察的结果将产生多个国家和国际合作，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。

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.
