Atmospheric, Snow and Firn Chemistry Studies for Interpretation of WAIS-Divide Cores

Frey/0636929该奖项支持一个项目，以了解最近的大气化学变化，以及雪，积雪和冰记录的历史变化如何影响南极洲的大气光化学。将对选定的气体、气象和雪的物理特性进行大气、雪和雪芯测量，并建立雪-大气交换模型。 该项目的智力价值是，它将导致更好地了解南极洲西部的大气化学，其与积雪的双向联系，以及它如何对区域影响作出反应。 这项工作至少有四个更广泛的影响。第一是研究生和本科生的教育。一名博士后研究员和一名研究生将开展大部分工作，一些本科生将参与其中。其次，参与WAIS划分核心计划将被用来帮助招募代表性不足的群体作为加州大学默塞德学生。作为加州大学默塞德在圣华金河谷的外展工作的一部分，圣华金河谷的学生在加州大学系统中的代表性不足，PI和共同PI为未来的学生、社区大学和高中教育工作者以及其他团体进行了简短的研究会谈。他们将开发一个这样的谈话突出这个项目。在这些招聘会谈中包括高调的研究已被证明是一种有效的方式，以促进对话，并在加州大学默塞德感兴趣的学生。第三，像这样的讲座也有助于提高公众的科学素养。PI和格拉德生都将寻求机会与K-14和社区观众分享项目信息。第四，研究结果将广泛传播给科学界，研究人员将寻求传递函数的其他应用，作为改善冰芯解释的工具。这项研究是高度合作的，并利用了其他一些团体的专业知识和数据。

Frey/0636929This award supports a project to understand how recent changes in atmospheric chemistry, and historical changes as recorded in snow, firn and ice, have affected atmospheric photochemistry over Antarctica. Atmospheric, snow and firn core measurements of selected gas, meteorological and snow physical properties will be made and modeling of snow-atmosphere exchange will be carried out. The intellectual merit of the project is that it will lead to a better an understanding of the atmospheric chemistry in West Antarctica, its bi-directional linkages with the snowpack, and how it responds to regional influences. There are at least four broader impacts of this work. First is education of university students at both the graduate and undergraduate levels. One postdoctoral researcher and one graduate student will carry out much of the work, and a number of undergraduates will be involved. Second, involvement with the WAIS-Divide coring program will be used to help recruit under-represented groups as UC Merced students. As part of UC Merced's outreach efforts in the San Joaquin Valley, whose students are under-represented in the UC system, the PI and co-PI give short research talks to groups of prospective students, community college and high school educators and other groups. They will develop one such talk highlighting this project. Including high-profile research in these recruiting talks has proven to be an effective way to promote dialog, and interest students in UC Merced. Third, talks such as this also contribute to the scientific literacy of the general public. The PI and grad student will all seek opportunities to share project information with K-14 and community audiences. Fourth, results of the research will be disseminated broadly to the scientific community, and the researchers will seek additional applications for the transfer functions as tools to improve interpretation of ice-cores. This research is highly collaborative, and leverages the expertise and data from a number of other groups.
