中文摘要
OCE-0648397来自佛罗里达州立大学、夏威夷大学和华盛顿大学的科学家将继续在印度洋(I8S/I9N、I6S、I7N或S4P)的游轮上继续CLIVAR/CO2重复水文学计划中的痕量金属部分。研究人员将使用他们干净的玫瑰花结/GoFlo系统以1‘间距(12到1000米)收集痕量金属剖面。这些样品将在船上使用流动注射分析来分析溶解的铝和铁。将收集和酸化样品,以便使用同位素稀释电感耦合等离子体质谱(ICPMS)和/或标准添加ICPMS进行岸上溶解的锰、铁、钴、镍、铜、锌、镉和铅的分析。这些样品的胶体部分将用切向流超滤(1000Da)获得,低分子量部分将分析Al、Mn、Fe、Co、Ni、Cu、Zn、Cd和Pb。此外,还将分析悬浮物质过滤器中的颗粒铝、铁和其他微量元素。除海水样本外,还将使用微孔均匀沉积撞击器(Moudi)串级冲击器采集气溶胶样本,以获得粒度分级的气溶胶样本,分析总气溶胶Al和Fe以及超纯水溶性气溶胶Al、Fe、其他微量元素和主要离子。在更广泛的影响方面,来自盆地尺度溶解和颗粒微量元素剖面的结果与总和可溶气溶胶微量元素数据相结合,将增进我们对全球海洋生物地球化学循环的理解,并提高海洋/大气碳循环耦合模式的预测能力。作为该项目的一部分,佛罗里达州立大学的两名研究生、夏威夷大学的一名博士后和一名研究生以及华盛顿大学的一名研究生将得到支持和培训。
英文摘要
OCE-0648397Scientists from Florida State University, the University of Hawaii, and the University of Washington will continue the trace metal component of the CLIVAR/CO2 Repeat Hydrography Program with cruises in the Indian Ocean (I8S/I9N, I6S, I7N or S4P). The researchers will use their clean rosette/GoFlo system to collect trace metal profiles at 1' spacing (12 depths to 1000 m). These samples will be analyzed on board for dissolved Al and Fe using Flow Injection Analysis. Subsamples will be collected and acidified for shore-based analysis of dissolved Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb using either isotope dilution inductively coupled plasma mass spectrometry (ICPMS) and/or standard additions ICPMS. The colloidal fraction of these samples will be obtained using tangential flow ultrafiltration (1000Da) and the low molecular weight fraction will be analyzed for Al, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb. In addition, suspended matter filters will be analyzed for particulate Al, Fe, and other trace elements. Besides seawater samples, aerosol samples also will be collected using a MOUDI (micro-orifice uniform deposit impactor) cascade impactor to obtain size-fractionated aerosol samples that will be analyzed for total aerosol Al and Fe, and ultrapure water soluble aerosol Al, Fe, other trace elements, and major ions. In terms of broader impacts, results from basin scale sections of dissolved and particulate trace elements combined with the total and soluble aerosol trace element data will improve our understanding of global ocean biogeochemical cycles, as well as improve the predictive capabilities of coupled ocean/atmospheric carbon cycle models. Two graduate students from Florida State University, one post-doc and one graduate student from the University of Hawaii, and one graduate student from the University of Washington will be supported and trained as part of this project.
