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.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。该奖项资助购买一台 Picarro L1102-ia 分析仪（用于波长扫描腔衰荡光谱）、两台 Thermo Delata V+ 质量分析仪光谱仪和一台具有双入口和多重制备系统的 Elementar Isoprime，用于替换 Lamont-Doherty Earth 稳定同位素设施中老化的分析设备天文台（LDEO）。这些新仪器将使 LDEO 和其他地方的众多研究人员能够继续进行前沿研究，包括对水、碳酸盐样品和有机样品（包括树木年轮纤维素和特定化合物）中的稳定同位素进行高精度分析。有机提取物。 此外，新仪器在支持现有气候学研究人员的同时，也将在生物地球科学领域开展新的研究工作。按照目前的设想，新的 LDEO 生物地球科学研究仪器集群将支持研究项目，以促进古气候学、水文学、古水文学、古海洋学和生物学领域合作和综合研究的新途径。更广泛的影响包括维持高质量的国家和国际焦点古气候研究的重点，以及让多元化的本科生和研究生骨干参与天文台研究的广泛计划。 计划利用另一项由 NSF 资助的活动——中学实地研究计划 (SSFRP)——为来自纽约市行政区高中的数十名代表性不足的少数族裔高中生提供实践研究和指导。
