This award is for an add-on to a funded field program to investigate the incipient rift located on the east side of the East Pacific Rise at 2 degrees 40'N by E. Klein and D. Smith (0099154). This incipient rift is volcanically active and may provide the unique opportunity of sampling the melting regime under the EPR with increasing distance from the axis. This add-on would carry out theoretical modeling of the upwelling and melting reime in order to improve understanding of the melt production and migration bvelow the EPR. The PI will work with M. Spiegelman to modify existing 2D mantle flow and melt models to include the incipient rift. After that, 3D models will be developed and tested against geochemical data.

该奖项是对E. Klein和D. Smith（0099154）资助的一个实地项目的补充，该项目旨在调查位于东太平洋隆起东侧北纬2度40度的早期裂谷。这个早期裂谷是火山活动的，可能提供了独特的机会，随着距离轴的距离增加，在EPR下对融化情况进行采样。该附加组件将对上升流和熔融过程进行理论建模，以提高对EPR以下熔体产生和迁移的理解。PI将与M. Spiegelman合作修改现有的二维地幔流动和熔融模型，以包括早期裂谷。之后，将开发3D模型，并根据地球化学数据进行测试。
