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

麦康奈尔/0839093该奖项是根据2009年《美国复苏和再投资法案》(公法第111-5条)资助的。该奖项支持一个项目，该项目利用WAIS Divide深核通过一套综合的化学和生物分析来调查亚年度分辨率的最后一次冰川消融。该项目的学术价值在于，这些分析与其他分析相结合，将利用WAIS高积雪分割点的优势，产生南极深部冰芯中时间分辨率最高的冰川-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，综合记录将对全球气候动态和突变产生新的见解。拟议的化学、生物和元素示踪剂测量也将用于处理世界农业信息系统划分的所有科学主题。该项目的更广泛影响包括教育和外联活动，如向当地K-12学生进行多次演示；学生和教师参与实验室工作的机会；在加利福尼亚州少数民族人口占多数的圣安娜、康普顿和科斯塔梅萨的学区开展地球科学教师培训计划；以及制定高中课程。还计划进行广泛的研究生和本科生参与，包括一名博士后助理、一名研究生和一名本科生参与DRI的每小时工作；一名加州大学欧文分校(UCI)的研究生和本科生；以及一名密歇根州立大学的博士后研究员。学生招募将从代表不足的团体中进行，这些团体建立在长期参与记录的基础上，将包括NSF资助的加州少数群体参与联盟(CAMP)和蒙大拿州美国印第安人研究机会(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).
