9422169 Blum This award provides partial (60%) funding for the acquisition of a multi-collector thermal ionization source mass spectrometer to be installed and operated in the Department of Earth Sciences at Dartmouth College. The institution is committed to providing the remaining funds necessary for this instrument acquisition. The equipment is to be used primarily in the research and teaching programs of nine faculty members in the Department of Earth Sciences at Dartmouth who have a need for accurate measurements of radiogenic isotopes. Their current research projects include: (1) Mineral weathering studies, soil formation processes and marine strontium evolution; (2) Base cation cycling in forest ecosystems; (3) Anthropogenic lead mobility in soil and ground water; (4) Geochemistry of terrestrial impacts; (5) Petrogenesis of granite and metamorphic rocks; and (6) Establishment of migratory patterns for long-distance migrant songbirds. ***

小行星9422169 该奖项提供了部分（60%）的资金，用于购买一个多收集器热电离源质谱仪安装和运行在地球科学系在达特茅斯学院。该机构致力于提供购买这一仪器所需的剩余资金。 该设备主要用于达特茅斯地球科学系9名教员的研究和教学计划，他们需要精确测量放射性同位素。他们目前的研究项目包括：（1）矿物风化研究、土壤形成过程和海洋锶演变;（2）森林生态系统中的碱阳离子循环;（3）土壤和地下水中人为铅的流动性;（4）陆地影响的地球化学;（5）花岗岩和变质岩的岩石成因;（6）确定长距离迁徙鸣禽的迁徙模式。 ***
