Geophysical Data Centers: Impact of Data-Intensive Programs

摘要

At its meeting in May 1974, the Geophysics Research Board (GRB) Committee on Data Interchange and Data Centers (CDIDC) recommended that a special study be undertaken regarding new demands that are being placed on World Data Centers (WDCs) and associated national data centers by large-scale geophysics programs. The recommendation was strongly supported by the GRB. Thomas Malone, chairman of the GRB, then asked Carl Savit to visit data centers in the United States and to prepare a letter report on his findings. Subsequently, the Geophysical Data Panel (GDP) of the CDIDC was formed, with Mr. Savit as chairman. The charge to the GDP was to amplify and substantiate the findings of the letter report. The resulting report consists of two parts. In the first part the findings and recommendations of the Panel are set forth and discussed. The operation of some typical World Data Centers and associated national data centers is described, and the impact of new data forms and quantities on them is considered. The second part contains the results of a survey of digital data quantities from past, ongoing, and planned large-scale geophysics programs.
