This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This award funds the acquisition of one Picarro L1102-ia analyzer (for wavelength-scanned cavity ring-down spectroscopy), two Thermo Delata V+ mass spectrometers, and one Elementar Isoprime with Dual Inlet and Multiprep systems to replace aging analytical equipment in the stable isotope facility at the Lamont-Doherty Earth Observatory (LDEO). These new instruments will allow a broad array of researchers at the LDEO, and elsewhere, to continue their cutting-edge research involving high precision analysis of stable isotopes in water, carbonate samples, and organic samples, including tree-ring cellulose and compound-specific organic extracts. Furthermore, the new instruments, while supporting existing researchers in climatology, will also new research endeavors in the field of biogeosciences. As currently envisioned, a new LDEO Biogeoscience Research Instrument Cluster would support research projects that serve to catalyze new avenues of collaborative and integrative research in paleoclimatology, hydrology, paleohydrology, paleoceanography, and biology.The broader impacts involve maintaining a high quality national and international focal point for paleoclimate research as well as an extensive plan to involve a diverse cadre of undergraduate and graduate students in the research of the Observatory. There are plans to leverage another NSF-funded activity -- the Secondary School Field Research Program (SSFRP) -- to provide hand-on research and mentoring for dozens of underrepresented minority high-school students drawn from New York City borough high schools.

该奖项是根据2009年的《美国恢复和再投资法》（公法111-5）资助的。该奖项资助了一项奖项，该奖项资助了一项PICARRO L1102-IA分析仪（用于波长扫描的腔腔环形镜检查频谱），两个Thermo delata V+质量光谱仪和一个基本设备，并用Dual Isprime替换了型号的设备，并将其替换为元素，以替换型元素，并替换了元素分析的设备。 Lamont-Doherty地球天文台（LDEO）。这些新仪器将允许LDEO和其他地方的大量研究人员继续其尖端研究，涉及对水，碳酸盐样品和有机样品的高精度分析，包括树环纤维素和复合特异性有机提取物。 此外，新工具在支持现有研究人员的气候学方面还将在生物科学领域进行新的研究。正如当前所设想的那样，一个新的LDEO生物盖科学研究仪器组合将支持研究项目，这些项目促进了新的合作和综合研究的新途径天文台的研究。 有计划利用NSF资助的另一项活动 - 中学实地研究计划（SSFRP） - 为数十个来自纽约市自治市镇高中吸引的代表性不足的少数民族高中生提供手工研究和指导。
