This project is a second-generation analysis of the ICEMELT and HOTSPOT data sets that will focus on four areas where additional work could lead to a fundamental new understanding of plume dynamics and plume-ridge interactions at Iceland. This work will (1) determine seismic velocity structure in the crust and uppermost mantle, (2) constrain upper mantle flow from mantle anisotropy, (3) improve mantle velocity structures by application of advanced methods, and (4) integrate seismic and geodynamic models.

这一项目是对冰岛电子气象监测站和热点卫星数据集的第二代分析，将侧重于四个领域，在这四个领域中，进一步的工作可能导致对冰岛的羽流动力学和羽流-洋脊相互作用有一个根本性的新认识。 本文的工作将（1）确定地壳和上地幔的地震速度结构，（2）从地幔各向异性中约束上地幔流动，（3）应用先进的方法改善地幔速度结构，（4）整合地震和地球动力学模型。
