Shona and Discovery Seamount Chains, South Atlantic - geochemistry program

获奖（0526529）类智力成绩： 这项研究资助了纽约哥伦比亚大学的一名美国研究人员参加由德国政府资助的2006年4月至6月在R/V Polarstern上进行的国际合作疏浚巡航。 这次航行的目的是在南大西洋绍纳海脊-流星海隆-厄古拉斯海脊-海隆角和发现海隆附近进行地球物理和岩石学研究。 更好地了解这部分海底非常重要，因为它代表了南大西洋的主要水深异常，通过这次航行，将首次对其进行彻底采样。 对南大西洋沿着相似地貌进行的年代递进式火山研究有助于限制板块运动和全球构造重建。 为了改进这些模型，需要对以绍纳和发现号热点为代表的羽流轨迹进行年代测定。 在巡航中将收集一套全面的样本。更广泛的影响：这项研究支持了拉蒙特-多尔蒂地球观测站的一名女研究员，她正在重返工作岗位。 它还涉及德国-美国-南非-荷兰的国际合作。

AWARD (0526529) ClassIntellectual Merit: This research funds the participation of a US researcher from Columbia University in New York on an international, collaborative dredging cruise funded by the German government on the R/V Polarstern from April to June 2006. The cruise objective is to carry out a geophysical and petrological study in the South Atlantic Ocean in the vicinity of the Shona Ridge - Meteor Rise - Agulhas Ridge - Cape Rise and Discovery Seamount. A better understanding of this part of the seafloor is important because it represents major bathymetric anomalies in the South Atlantic, and through this cruise, they will be thoroughly sampled for the first time. Age progressive volcanic studies along similar features in the South Atlantic have been instrumental in constraining plate motions and global tectonic reconstructions. The dating of plume tracks, such as those represented by the Shona and Discovery hotspots is required to improve such models. On the cruise a comprehensive suite of samples will be collected. Their geochemical characterization will be funded through a different award.Broader impacts: The research supports a female researcher at the Lamont-Doherty Earth Observatory who is returning to the workforce. It also involves a German-American-South African-Dutch international collaboration.
