This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This project involves the renovation of the second floor of the "New Core Lab" at the Lamont Doherty Earth Observatory in order to create the Lamont Center for Biogeochemistry. This will enable the institution to support collaborative activities in an increasingly inter-disciplinary field and to make it easier for researchers to share high-end analytical facilities. It will allow the use of modern biogeochemical research techniques that are difficult to use in the current facilities.The program of work includes interior renovation, plumbing, HVAC, electrical, building controls, fire protection, casework and other smaller items. The project will replace the mechanical and electrical infrastructure that serves the second floor. This will include all new electrical distribution and piping. The plumbing systems serving the laboratories will also be replaced, but the vast majority of the work will be on the heating, ventilating and cooling side. The renovated facility will help to satisfy the need for interdisciplinary research that bridges across the biological, atmospheric, geological, oceanographic, and hydrological sciences and that increases our understanding of the two-way coupling between biological systems and the physical and chemical characteristics of soils, sediments, air, or water. Examples of the type of research that will be done in the renovated facility includes: the reconstruction of past hydroclimate conditions using oxygen isotope measurements from trees without annual rings and the study of the Asian monsoon for the past millennium using tree-ring widths, density, and isotopic indices; the use of uranium series geochemistry to reconstruct deep-sea particle fluxes and past changes in Antarctic upwelling and productivity; estimating changes in deep-ocean carbonate chemistry during the last glacial cycle; the reconstruction of past variations in ocean circulation, sea-surface temperature gradients, and terrestrial climate using geochemical analyses of foraminifer shells in deep-sea sediments; the timing and abruptness of ice sheet instability events; the reconstruction of past changes in ocean acidity and hence atmospheric carbon dioxide levels using boron isotopes in planktonic foraminifera and coral; the response of planktonic ecosystems to physical forcing resulting from global climate change; the microbial assemblage in deep-sea sediments, the pattern of active and pathogenic microbes in the Hudson River estuary, and the microbes associated with soil carbon sequestration. The proposed renovations will also provide facilities that will be used to provide research experiences for undergraduates and high-school students.

该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。该项目涉及在拉蒙特·多尔蒂（Lamont Doherty）地球天文台的“新核心实验室”的二楼进行翻新，以创建Lamont Biogeochemistry中心。 这将使该机构能够在越来越多的跨学科领域中支持协作活动，并使研究人员更容易共享高端分析设施。 它将允许在当前设施中难以使用现代生物地球化学研究技术。工作计划包括室内装修，管道，HVAC，HVAC，电气，建筑物控制，防火，防火，案例工作和其他较小的物品。 该项目将取代服务二楼的机械和电气基础设施。这将包括所有新的电气分配和管道。为实验室服务的管道系统也将被替换，但是绝大多数工作将位于供暖，通风和冷却方面。 经过翻新的设施将有助于满足对生物，大气，地质，海洋学和水文科学桥梁的跨学科研究的需求，这增加了我们对生物系统与物理和化学特征之间的双向耦合的理解，土壤，沉积物，空气或水。在翻新的设施中将进行的研究类型的例子包括：使用不含年度环的树木的氧同位素测量以及过去千年的亚洲季风研究使用树环，密度，密度，同位素和同位素指数的亚洲季风的研究；使用铀序列地球化学重建深海粒子通量以及南极上升和生产力的过去变化；估计上一个冰川周期中深碳酸盐化学的变化；通过对深海沉积物中有孔虫壳的地球化学分析，对海洋循环，海面温度梯度和陆地气候的过去变化的重建；冰盖不稳定性事件的时机和突变；使用浮游有孔虫和珊瑚中的硼同位素重建了过去海洋酸度和大气二氧化碳水平的变化；浮游生气生态系统对全球气候变化产生的身体强迫的反应；深海沉积物中的微生物组合，哈德逊河河口中的活跃和致病微生物的模式以及与土壤碳固醇相关的微生物。 拟议的翻新工程还将提供设施，这些设施将用于为大学生和高中生提供研究经验。
