项目摘要

1043471/KaplanThis award supports a project to obtain the first set of isotopic-based provenance data from the WAIS divide ice core. A lack of data from the WAIS prevents even a basic knowledge of whether different sources of dust blew around the Pacific and Atlantic sectors of the southern latitudes. Precise isotopic measurements on dust in the new WAIS ice divide core are specifically warranted because the data will be synergistically integrated with other high frequency proxies, such as dust concentration and flux, and carbon dioxide, for example. Higher resolution proxies will bridge gaps between our observations on the same well-dated, well-preserved core. The intellectual merit of the project is that the proposed analyses will contribute to the WAIS Divide Project science themes. Whether an active driver or passive recorder, dust is one of the most important but least understood components of regional and global climate. Collaborative and expert discussion with dust-climate modelers will lead to an important progression in understanding of dust and past atmospheric circulation patterns and climate around the southern latitudes, and help to exclude unlikely air trajectories to the ice sheets. The project will provide data to help evaluate models that simulate the dust patterns and cycle and the relative importance of changes in the sources, air trajectories and transport processes, and deposition to the ice sheet under different climate states. The results will be of broad interest to a range of disciplines beyond those directly associated with the WAIS ice core project, including the paleoceanography and dust- paleoclimatology communities. The broader impacts of the project include infrastructure and professional development, as the proposed research will initiate collaborations between LDEO and other WAIS scientists and modelers with expertise in climate and dust. Most of the researchers are still in the early phase of their careers and hence the project will facilitate long-term relationships. This includes a graduate student from UMaine, an undergraduate student from Columbia University who will be involved in lab work, in addition to a LDEO Postdoctoral scientist, and possibly an additional student involved in the international project PIRE-ICETRICS. The proposed research will broaden the scientific outlooks of three PIs, who come to Antarctic ice core science from a variety of other terrestrial and marine geology perspectives. Outreach activities include interaction with the science writers of the Columbia's Earth Institute for news releases and associated blog websites, public speaking, and involvement in an arts/science initiative between New York City's arts and science communities to bridge the gap between scientific knowledge and public perception.
该奖项支持从WAIS分界冰芯中获得第一套基于同位素的物源数据的项目。由于缺乏来自WAIS的数据,人们甚至无法了解是否有不同来源的灰尘在南纬的太平洋和大西洋地区吹过。在新的WAIS冰分界核中对尘埃进行精确的同位素测量是特别必要的,因为这些数据将与其他高频代理协同集成,例如尘埃浓度和通量,以及二氧化碳。更高分辨率的代理将弥合我们对同一年代、保存完好的岩心的观察之间的差距。该项目的智力价值在于所提出的分析将有助于WAIS划分项目的科学主题。无论是主动驱动者还是被动记录者,尘埃都是区域和全球气候中最重要但最不为人所知的组成部分之一。与沙尘气候建模者的合作和专家讨论将导致对沙尘和过去大气环流模式以及南纬地区气候的理解取得重要进展,并有助于排除不太可能到达冰盖的空气轨迹。该项目将提供数据,以帮助评估模拟沙尘模式和循环的模型,以及不同气候状态下沙尘来源、空气轨迹和运输过程以及向冰盖沉积变化的相对重要性。除了与WAIS冰芯项目直接相关的学科外,这些结果将对包括古海洋学和沙尘-古气候学社区在内的一系列学科产生广泛的兴趣。该项目的更广泛影响包括基础设施和专业发展,因为拟议的研究将启动LDEO与其他具有气候和尘埃专业知识的WAIS科学家和建模者之间的合作。大多数研究人员仍处于职业生涯的早期阶段,因此该项目将促进长期关系。这包括一名来自缅因州的研究生,一名来自哥伦比亚大学的本科生,他将参与实验室工作,此外还有一名LDEO博士后科学家,可能还有一名学生参与国际项目pierre - icetrics。拟议的研究将拓宽三位pi的科学视野,他们从各种其他陆地和海洋地质学的角度来研究南极冰芯科学。外联活动包括与哥伦比亚地球研究所的科学作家互动,发布新闻和相关博客网站,公开演讲,参与纽约市艺术和科学界之间的艺术/科学倡议,以弥合科学知识和公众认知之间的差距。
