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

McConnell/0839093该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该奖项支持一个项目，该项目使用WAIS Divide深芯，通过一套综合的化学和生物分析，以次年度分辨率调查末次冰期。该项目的智力价值是，这些分析与其他分析相结合，将利用西澳大利亚国际科学研究所分水岭高积雪量的地点，产生任何南极深层冰芯的最高时间分辨率的冰川地球化学和气体记录。与其他高分辨率格陵兰核心（GISP 2和GRIP）和较低分辨率的南极核心，结合记录将产生新的见解全球气候动态和突变。拟议的化学，生物和元素示踪剂测量也将用于解决所有的WAIS鸿沟科学主题。 该项目更广泛的影响包括教育和推广活动，如向当地K-12学生进行多次演讲;为学生和教师提供参与实验室工作的机会;在加州少数民族聚居的圣安娜、康普顿和科斯塔梅萨学区开展地球科学教师培训计划;以及制定高中课程。广泛的研究生和本科生参与也计划，将包括一个博士后助理，一个研究生，并在DRI本科小时参与;在加州大学欧文分校（UCI）的研究生和本科生;和在密歇根州立大学博士后研究员。学生的招募将从代表性不足的群体中进行，这些群体建立在长期参与的记录上，将包括NSF资助的加州少数民族参与联盟（CAMP）和蒙大拿州美国印第安人研究机会（AIRO）。该奖项不涉及南极洲的实地考察。

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).This award does not involve field work in Antarctica.
