项目摘要
This Small Grants for Exploratory Research (SGER) project involves the deployment of a newly developed instrument aboard a research cruise vessel (R/V Wecoma) in the North Pacific Ocean region in the spring and early summer of 2004. This cruise of opportunity, from Guam to Oregon via Hawaii, is dedicated to understanding the exchange of organic halogen compounds between the ocean and the atmosphere. This project will involve first measurements of the dihalogen gases, chlorine (Cl2), bromine (Br2), iodine (I2), bromochlorine (BrCl), and iodochlorine (ICl), over the open ocean. The measurement method is based on atmospheric pressure chemical ionization mass spectrometry (API/CIMS), variants of which have been demonstrated by other researchers to be extremely sensitive and selective for atmospheric trace components. These first measurements, if successful, will provide valuable information on the role of these gases impact on the chemistry of ozone, hydrocarbons and sulfur compounds in the marine boundary layer, and could substantially revise our understanding of atmospheric photochemistry in this region. A second, even more exploratory measurement involves the quantification of the halogen oxides, ClO and BrO, using chemical conversion to species (deuterated haloacetones) that can be measured by API/CIMS.The broader impacts of this research include providing field research experience for two graduate students and one post-doctoral fellow. In addition, this research contributes to the goals of the Surface Ocean Lower Atmosphere Study (SOLAS) program by helping to understand the composition of the marine atmospheric boundary layer and provide constraints on exchange of these gases with the ocean surface layer. In the longer view, this research will improve understanding of the oxidation processes operative in the marine boundary layer, and thus will better constrain the fate and lifetime of gases important for the earth's climate.
这一探索性研究小额赠款项目涉及于2004年春季和初夏在北太平洋区域的一艘研究游轮(R/V Wecoma)上部署一个新开发的仪器。 这次机会号的巡航,从关岛经夏威夷到俄勒冈州,致力于了解海洋和大气之间有机卤素化合物的交换。 该项目将首次测量公海上空的二卤气体,即氯(Cl 2)、溴(Br 2)、碘(I2)、溴氯(BrCl)和碘氯(ICl)。 测量方法是基于大气压化学电离质谱法(API/CIMS),其变体已被其他研究人员证明是非常敏感和选择性的大气痕量成分。 这些首次测量如果成功,将提供关于这些气体对海洋边界层中臭氧、碳氢化合物和硫化物的化学作用的有价值的信息,并可能大大修改我们对该区域大气光化学的理解。 第二,甚至更探索性的测量涉及的卤素氧化物,ClO和BrO的定量,使用化学转化为物种(氘代卤代丙酮),可以测量由API/CIMS。这项研究的更广泛的影响,包括为两名研究生和一名博士后研究员提供实地研究经验。 此外,这项研究有助于了解海洋大气边界层的组成,并提供对这些气体与海洋表层交换的限制,从而有助于实现表面海洋低层大气研究(SOLAS)计划的目标。 从长远来看,这项研究将提高对海洋边界层氧化过程的理解,从而更好地限制对地球气候重要的气体的命运和寿命。
