该合同为钻前活动提供支持 与一个项目有关，其最终目标是获得 几乎连续的，有序的记录海洋产量 火山在其主要的屏蔽建设阶段的长时间间隔， 活动 只有一小部分的输出和历史的任何 通过地表可以到达夏威夷各个火山 暴露，这是不可能的，这些内部 除非通过深钻，否则火山永远不会暴露出来。 要解决的主要科学问题涉及 热点的性质，特别是其组成和来源 他们可能代表的“羽流”，以及上升流如何 物质与岩石圈相互作用的时间尺度为105至 106年 该奖项支持的具体活动 包括：1）确定选址和评估 允许问题; 2）最后确定，并提供详细的理由， 建议的孔深; 3）审查和修改，如果 钻井计划和井下测量计划， 确保所建议的孔可以根据需要进行记录， 科学目标;以及4）确定 完整的科学团队

This award provides support for pre-drilling activities connected with a project whose ultimate objective is to obtain a nearly continuous, ordered record of the output of an oceanic volcano over a long interval of its main shield-building phase of activity. Only small fractions of the output and history of any individual Hawaiian volcano are accessible through surface exposures and it is unlikely that the interiors of these volcanoes will ever be exposed except by deep drilling. The primary scientific questions to be addressed concern the nature of hot spots, in particular, the composition and origin of the "plumes" they may represent, and how the upwelling material interacts with the lithosphere on time scales of 105 to 106 years. The specific activities being supported by this award include: 1) finalizing the site selection and evaluating permitting issues; 2) finalizing, with detailed justification, the proposed hole depth; 3) reviewing and modifying, if necessary, the drilling plan and downhole measurements plan to insure that the proposed hole can be logged as necessary for the scientific objectives; and 4) determining the makeup of the complete science team.
