Upgrade of Sedimentary Geology Preparation and Marine Sedimentary Biogeochemistry Laboratories

0930002Sageman“本奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。”该奖项将为替换沉积地质学和生物地球化学设备提供资金。将改进或更换的主要项目是岩石锯、破碎箱、离心机、烤箱、天平、库电量计和分光光度计。所有计划增加的仪器都是旧的，维护成本增加，供应商停产。该设备将用于西北大学新装修的地球与行星科学系。pi将使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通过地球调查海洋-大气的演变？利用互补方法测定沉积物碳、硫、铁和磷酸盐。这些元素和它们的同位素提供了对地球的一瞥？其氧化还原史和pi将集中于新元古代的过渡。元素丰度和同位素比值也将用于研究海洋缺氧随时间的变化（古生代和中生代）。评估对元素循环和有机碳埋藏速率的影响。由于这些仪器是沉积地质学研究的基础，它们的影响将跨越该系的本科生和研究生。向高中理科学生展示地球化学实验室技术的iLabs项目也将从此次收购中受益。项目还将允许东北伊利诺伊大学（NEIU），一个少数民族就读的大型校园，送学生谁将有机会获得新的仪器。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. ***
