D’AndreaEAR-2117745This Major Research Instrumentation (MRI) Program grant supports acquisition of a mass spectrometer for study of stable isotopies proxies of climate and environmental processes as recorded in organic molecules in ocean and lake sediments and tree rings. The instrument will support the research of over twelve scientists at Lamont-Doherty Earth Observatory (LDEO) and the educational program that impacts many undergraduate and graduate students trained at LDEO annually. The instrument will also support students at Barnard College that will gain hand-on experiential learning in methods of stable isotope mass spectrometry through an extant summer internship Program at LDEO.A Thermo DELTA V Plus Mass Spectrometer with gas chromatograph and liquid chromatograph front ends will be acquired enabling carbon and hydrogen isotopic analysis of polar and thermo-labile compounds including organic acids, carbohydrates, amino acids, phospholipids, and glycolipids and analysis of carbon and hydrogen stable isotopes in specific lipids. The instrument would support interdisciplinary research including studies of the degradation of petroleum products in the ocean, contamination processes in groundwater aquifers, metabolic pathways within harmful algal and bacterial taxa, microbial controls on methane production in ocean margin sediments, paleoclimate and the evolution of terrestrial plants.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

D 'Andrea-2117745这项主要研究仪器（MRI）计划拨款支持购买质谱仪，用于研究海洋和湖泊沉积物和树木年轮中有机分子记录的气候和环境过程的稳定同位素代理。 该仪器将支持拉蒙特-多尔蒂地球观测站（LDEO）的12名科学家的研究，以及每年在LDEO培训的许多本科生和研究生的教育计划。 该仪器还将支持巴纳德学院的学生，他们将通过LDEO现有的暑期实习计划获得稳定同位素质谱法的实践经验学习。将获得带有气相色谱仪和液相色谱仪前端的Thermo DELTA V Plus质谱仪，从而能够对极性和热不稳定化合物（包括有机酸、碳水化合物、氨基酸、磷脂和糖脂以及特定脂质中碳和氢稳定同位素的分析。该文书将支持跨学科研究，包括研究石油产品在海洋中的降解、地下蓄水层的污染过程、有害藻类和细菌分类群内的代谢途径、微生物对海洋边缘沉积物中甲烷产生的控制，该奖项反映了NSF的法定使命，并被认为是值得通过使用基金会的学术价值和更广泛的影响审查标准。
