On-line Optical Storage Module for the Analysis of Very Large Data Sets

该奖项提供了大约一半的资金，用于购买安装在哈佛大学地球和行星科学系的光学大容量存储模块。该存储系统的容量为165千兆字节，将由一台计算机控制，该计算机可通过哈佛大学以太网系统和国家科学基金网络系统访问。自1972年以来，全球地震台网记录的数字地震图已经构成了大约100千兆字节的科学数据，具有许多潜在的应用，如震源研究和深地层析成像。数据集非常大，而且还在不断增长，它目前驻留在5000个磁带上。直接、在线地访问传输到光存储系统的这些数据是科学处理这些资源的唯一实际手段。

This award provides approximately one-half the funds needed to acquire an optical mass storage module to be installed in the Department of Earth and Planetary Sciences at Harvard University. The storage system has a capacity of 165 gigabytes and will be controlled by a computer which can be accessed by the Harvard university-wide Ethernet system and the national NSFnet system. Digital seismograms recorded by the global seismic network since 1972 already constitute approximately 100 gigabytes of scientific data with many potential applications such as studies of seismic sources and deep-earth tomographic imaging. The data set is very large and growing, and it currently resides on 5000 magnetic tapes. Direct, on line, access to this data transferred to the optical storage system is the only practical means of scientifically processing this resource.
