Harvard University is committed to providing the remaining half of the cost of acquisition. The network is used to support research across a range of fundamental earth science problems including the generation of the Earth's magnetic field in the core, the fine structure of the Earth's rotation, and the dynamics of the Earth's mantle. ***
