JUDGE Project: A Continental Scientific Drilling into Subduction Zone, (4) Program Plan of the JUDGE Project

摘要

Execution plan of the JUDGE project is discussed and presented. Several steps are necessary before we start drilling of the main hole of the JUDGE project; that is, (1) site survey, (2) technology development, (3) drilling and down-hole monitoring of pilot holes, and (4) establishment of an archive for data and sample distribution. It is concluded that the organizational structure and decision-making process should be kept as flexible as possible until the completion of the pilot holes - This is because repeated evaluation and assessment of the results obtained through steps (1) to (3) should be reflected for the final site selection and technology' development - Therefore, the program plan stated in this Chapter should be regarded as a possible design at the present level of knowledge.
