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.

该奖项支持对罗斯海西部阿达尔角地区海底山熔岩样本的研究。该地区的火山作用知之甚少，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。由于阿达尔角海山位于海洋岩石圈上，它们可能不受影响大陆地区喷发的熔岩的污染。这项为期一年的调查将收集2007年前往该地区的游轮收集的样本数据。它将确定海底山的年龄，描述它们的地幔来源，评估它们的起源模式，并判断进行更详细研究的潜力。就更广泛的影响而言，该项目将涉及研究生和本科生进行令人兴奋的实地考察，然后使用尖端的地球化学分析技术进行实验室工作。
