The Interagency Coordinating Group for Continental Scientific Drilling (ICG/CSD), composed of representatives from the Department of Energy (DOE), National Science Foundation (NSF), and U.S. Geological Survey (USGS), has devised a multiyear, multihole scientific research strategy for the U.S. Continental Scientific Drilling Program (CSDP). Using this strategic plan, the agencies of ICG/CSD expect to establish and maintain a management and operational infrastructure for continental scientific drilling.

Phase I is the initial 3-year, base scientific drilling program beginning in Fiscal Year 1991. Combined funding from the three agencies is expected to be about $3 million per year, to drill 10 to 15 shallow- to intermediate-depth holes over the 3-year period. The elements of Phase I are: targets of significant scientific importance at shallow and occasionally intermediate depths research using drill holes of opportunity continuing research and development related to CSDP activities archiving, storing and distributing drilling samples collecting, managing and distributing drilling and drilling-related data.
