ABSTRACTOCE-0752609OCE-0752351The GEOTRACES Program has adopted the sampling and sub-sampling system utilized by investigators from the University of Hawaii and Florida State University for their CLIVAR Repeat Hydrography trace metal work. To ensure the newly constructed GEOTRACES rosette sampling system can yield contaminant free seawater samples, the scientist propose to take their system on the GEOTRACES intercalibration cruises and assist with the evaluation and development of the programs sample acquisition, handling, and storage protocols. In addition, they plan to validate seawater iron measurements using high-resolution isotope dilution inductively coupled plasma mass spectrometry following magnesium hydroxide coprecipitation. As regards broader impacts, one postdoc from the University of Hawaii and one postdoc from Florida State University would be supported and trained as part of this project.

摘要OCE-0752609 OCE-0752351 GEOTRACES计划采用了夏威夷大学和佛罗里达州立大学的研究人员在CLIVAR重复水文学痕量金属工作中使用的取样和二次取样系统。 为了确保新建造的GEOTRACES玫瑰花采样系统能够产生无污染的海水样本，科学家建议将他们的系统带到GEOTRACES相互校准巡航中，并协助评估和制定样本采集，处理和存储协议的程序。 此外，他们计划在氢氧化镁共沉淀后使用高分辨率同位素稀释电感耦合等离子体质谱法来验证海水铁的测量。至于更广泛的影响，作为该项目的一部分，将支助和培训夏威夷大学的一名博士后和佛罗里达州立大学的一名博士后。
