Upgrade of Sedimentary Geology Preparation and Marine Sedimentary Biogeochemistry Laboratories

这个奖项是根据2009年《美国复苏和再投资法案》(公法111-5)资助的。该合同将为更换沉积地质学和生物地球化学设备提供资金。将被改进或更换的主要物品是岩锯、破碎机、离心机、烤箱、天平、库仑计和分光光度计。随着维护成本的增加和供应商的停产，所有计划增强的仪器都变得陈旧。该设备将用于西北大学新装修的地球和行星科学系。私人投资机构将利用这些仪器进行海洋沉积生物地球化学这一广泛主题的研究。PI使用对沉积物碳、硫、铁和磷的补充方法研究了地球-S历史上的海洋-大气演化。这些元素及其同位素提供了对地球的一瞥？S的氧化还原历史和PI将重点放在新元古代的转变上。元素丰度和同位素比率也将用于研究海洋随时间(古生代和中生代)的缺氧情况。将评估对元素循环和有机碳埋藏率的影响。由于这些仪器是沉积地质学研究的基础，它们的影响将从本科生到研究生。ILabs计划让高中理科学生接触到地球化学实验室技术，也将从这次收购中受益。项目还将允许东北伊利诺伊大学(NEIU)，一个大型少数族裔学生参加的校园，送那些将有机会接触到新仪器的学生。一般的古气候研究主题具有很高的社会重要性。***

0930002Sageman"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)." This award will provide funding to replace equipment for sedimentary geology and biogeochemistry. The main items which will be improved or replaced are a rock saw, shatterbox, centrifuge, ovens, a balance, coulometer and spectrophotometer. All instruments slated for augmentation are older with increasing maintenance costs and vendor discontinuance. The equipment will be used in the newly-renovated Department of Earth and Planetary Sciences at Northwestern. The PIs will use these instruments for research in the broad theme of marine sedimentary biogeochemistry. The PIs investigate the ocean-atmosphere evolution through Earth?s history using complimentary methods on sediment carbon, sulfur, iron and phosphate. These elements and their isotopes provide a glimpse into Earth?s redox histories and the PIs will focus on the Neoptroterozoic transition. Elemental abundances and isotope ratios will also be used to study ocean anoxia over time (Paleozoic and Mesozoic). The impacts on elemental cycling and organic carbon burial rates will be assessed. Because these instruments are so fundamental to sedimentary geology studies, their impact will span from undergraduate to graduate students in the department. The iLabs program, which exposes high school science students to geochemical laboratory techniques, will also benefit from this acquisition. Projects will also allow Northeaster Illinois University (NEIU), a large minority-attended campus, to send students who will have access to the new instrumentation. General paleoclimate research themes are of high societal importance. ***
