Collaborative Research: Participation in the GEOTRACES Intercalibration Cruise

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其CLIVAR重复水文示踪金属工作中使用的采样和子采样系统。为了确保新建造的GEOTRACES玫瑰取样系统能够产生无污染的海水样本，这位科学家建议将他们的系统带上GEOTRACES内部校准巡航，并协助评估和开发项目样本采集、处理和存储协议。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来验证海水铁的测量。至于更广泛的影响，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将作为该项目的一部分得到支持和培训。

The 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.
