This award supports the study of lava samples from seamounts in the Cape Adare region of the western Ross Sea. Volcanism in this area is poorly understood, and the geochemistry of these lavas may offer new insight into regional geodynamics and global mantle geochemistry. Because the Cape Adare seamounts are located on oceanic lithosphere, they may be free of the contamination that affects lavas erupted through continental areas. This one-year investigation will gather data on samples collected on a cruise to this region in 2007. It will determine seamount ages, characterize their mantle sources, assess models for their origin, and judge the potential for more detailed study. In terms of broader impacts, this project will involve graduate and undergraduate students in an exciting field expedition, followed by laboratory work using cutting-edge techniques for geochemical analyses.

该奖项支持了西罗斯海开普·阿达雷地区海湾的熔岩样品的研究。该地区的火山主义知之甚少，这些熔岩的地球化学可能为区域地球动力学和全球地幔地球化学提供新的见解。由于Adare Cape Adare海湾位于海洋岩石圈上，因此它们可能没有影响熔岩在大陆地区爆发的污染。这项为期一年的调查将收集2007年在该地区巡游上收集的样本的数据。它将确定海拔年龄，表征其地幔来源，评估其起源模​​型，并判断潜在的更详细的研究。在更广泛的影响方面，该项目将涉及研究生和本科生参加令人兴奋的实地考察，然后使用尖端的技术进行地球化学分析的实验室工作。
