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.

该奖项提供了大约一半的资金需要 以获取要安装在所述存储器中的光学海量存储模块， 哈佛大学地球与行星科学系。 存储系统容量为165千兆字节， 由一台计算机控制，可以通过哈佛 校园以太网系统和国家NSFnet系统。 全球地震台网记录的数字地震图 自1972年以来已经构成了大约100千兆字节的 具有许多潜在应用的科学数据，例如研究 地震源和深地层析成像。数据 set非常大，而且还在不断增长，目前位于5000个 磁带。直接在线访问传输的数据 光学存储系统是唯一可行的手段， 科学地处理这些资源。
