Collaborative Research: Integrated High Resolution Chemical and Biological Measurements on the Deep WAIS Divide Core

McConnell/0839093 该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。该奖项支持一个项目，利用 WAIS Divide 深核心，通过一套综合的化学和生物分析，以亚年分辨率研究末次冰消期。该项目的智力优势在于，这些分析与其他分析相结合，将利用 WAIS 分水岭的高积雪量，产生任何南极深层冰芯的最高时间分辨率的冰川生物地球化学和气体记录。与其他高分辨率格陵兰岩心（GISP2 和 GRIP）和较低分辨率的南极岩心一起，综合记录将为全球气候动态和突变提供新的见解。拟议的化学、生物和元素示踪测量也将用于解决所有 WAIS Divide 科学主题。该项目更广泛的影响包括教育和外展活动，例如向当地 K-12 学生进行大量演讲；学生和教师参与实验室工作的机会；在加利福尼亚州圣安娜、康普顿和科斯塔梅萨等少数族裔学区开展地球科学教师培训计划；和高中课程的开发。还计划让研究生和本科生广泛参与，其中包括一名博士后助理、一名研究生和本科生按小时参与 DRI；加州大学欧文分校 (UCI) 的研究生和本科生；以及密歇根州立大学的博士后研究员。学生招募将从长期参与记录的代表性不足的群体中进行，其中包括 NSF 资助的加州少数族裔参与联盟 (CAMP) 和蒙大拿州美洲印第安人研究机会 (AIRO)。

McConnell/0839093 This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This award supports a project to use the WAIS Divide deep core to investigate the Last Deglaciation at sub-annual resolution through an integrated set of chemical and biological analyses. The intellectual merit of the project is that these analyses, combined with others, will take advantage of the high snow accumulation WAIS Divide site yielding the highest time resolution glacio-biogeochemical and gas record of any deep Antarctic ice core. With other high resolution Greenland cores (GISP2 and GRIP) and lower resolution Antarctic cores, the combined record will yield new insights into worldwide climate dynamics and abrupt change. The proposed chemical, biological, and elemental tracer measurements will also be used to address all of the WAIS Divide science themes. The broader impacts of the project include education and outreach activities such as numerous presentations to local K-12 students; opportunities for student and teacher involvement in the laboratory work; a teacher training program in Earth sciences in the heavily minority Santa Ana, Compton, and Costa Mesa, California school districts; and development of high school curricula. Extensive graduate and undergraduate student involvement also is planned and will include one post doctoral associate, one graduate student, and undergraduate hourly involvement at DRI; a graduate student and undergraduates at University of California, Irvine (UCI); and a post doctoral fellow at MSU. Student recruitment will be made from underrepresented groups building on a long track record of involvement and will include the NSF funded California Alliance for Minority Participation (CAMP) and the Montana American Indian Research Opportunities (AIRO).
