项目摘要

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'AndreaeAR-2117745此主要研究仪器（MRI）计划赠款支持获得质谱仪，用于研究稳定的同位素代理，如海洋和湖泊沉积物和树环的有机分子中记录的气候和环境过程。该乐器将支持Lamont-Doherty Earth观测站（LDEO）的十二多名科学家的研究以及影响每年在LDEO培训的许多本科生和研究生的教育计划。该乐器还将通过Barnard College的学生提供支持的学生，该仪器将通过LDEO的扩展暑期实习计划获得稳定同位素质谱法的手工专家学习。磷脂，糖脂以及特定脂质中碳和氢稳定同位素的分析。该仪器将支持跨学科的研究，包括研究石油产品在海洋中的降解，地下水含水层中的污染过程，有害藻类和细菌分类群中的代谢途径，微生物对甲烷生产的微生物控制，对海距沉积物中的甲烷生产对海距沉积物中的甲烷生产，通过海拔植物的质疑和珍贵的批准。基金会的智力优点和更广泛的影响评论标准。
