MRI-R2: Acquisition of Stable Isotope Instrumentation for High Precision Paleoclimatic and Environmental Research at the Lamont Doherty Earth Observatory

该奖项是根据2009年美国复苏和再投资法案资助的（公法111-5）。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法），两台Thermo Delata V+质谱仪，和一个Elementar Isoprime双入口和多制备系统，以取代老化的分析设备在稳定同位素设施在拉蒙-Doherty Earth Observatory（英语：Doherty Earth Observatory）这些新仪器将使LDEO和其他地方的广泛研究人员能够继续进行尖端研究，包括对水，碳酸盐样品和有机样品中的稳定同位素进行高精度分析，包括树木年轮纤维素和化合物特定的有机提取物。 此外，新仪器在支持现有气候学研究人员的同时，也将推动地球科学领域的新研究努力。按照目前的设想，一个新的LDEO生物地球科学研究仪器集群将支持研究项目，这些项目将促进古气候学、水文学、古水文学、古海洋学、更广泛的影响包括保持一个高质量的国家和国际古气候研究的焦点，以及一个广泛的计划，涉及不同的本科生和研究生的干部天文台的研究。 有计划利用另一个国家科学基金会资助的活动-中学实地研究方案-为来自纽约市区高中的数十名代表性不足的少数民族高中生提供实践研究和指导。

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.
