Upgrading of Computer Equipment for Geophysical Studies

9614110 Nolet这笔赠款提供46,764美元，作为普林斯顿大学地球物理学系购置计算机设备费用的一半。具体地说，这些资金将在三年内用于购买一台SUN E3000计算机服务器，该服务器将配备多个中央处理器、扩展内存和大容量存储器。这种扩大的计算能力将用于一系列有趣和根本重要的地震学研究项目，包括：要求对巨大的地震学数据集进行反演的上地幔断层成像；利用横向不均匀地球模型制作合成的长周期地震图以证实实际数据集适用的反演方案的有效性；研究夏威夷基拉韦厄火山下方地震震源的时空分布，以更好地约束岩浆输送的机制和通道；利用基于高质量3-D地震数据的迭代恢复技术，可视化2-D和3-D褶皱生长和断层运动的运动学。***

9614110 Nolet This grant provides $46,764 as one-half support of the costs of acquiring computer equipment for the Geophysics faculty at Princeton. Specifically, these funds will be used over a three year period to acquire a SUN E3000 compute server will multiple CPU's, expanded memory and mass storage. This expanded computational ability will serve four faculty and their graduate students for a range of interesting and fundamentally important seismological research projects including, tomographic imaging of the upper mantle requiring inversion of huge seismological data sets, production of synthetic, long-period seismograms using laterally heterogeneous Earth models to ground truth the validity of inversion schemes applied to actual data sets, studies of the temporal and spatial distribution of earthquake foci beneath Kilauea volcano, Hawaii in order to better constrain the mechanisms and conduits for magma transport, and visualization of the kinematics of fold growth and fault motion in both 2-D and 3- D using iterative restoration techniques based on high-quality 3- D seismic data. ***
