Participation in the French Wireline Reentry Program DIANAUT

海洋地球科学的一个主要重点是了解 海洋演化中的水文地质过程 岩石圈现在已知地壳中流体的作用是 在改变地壳化学，控制 海水化学和冷却海洋岩石圈。 尽管海洋钻探提供了一种检查 这些过程的直接结果， 需要实验和重复观察来理解 这些过程发生的速率。这些实验是 最好通过在周期性的钻孔中重新进入来执行 或通过长期部署工具。的成本 钻井船作业导致国际社会 开发在钻孔中部署实验的替代方法。 该奖项将支持美国科学家参与与法国 同事们使用潜水器将仪器放入钻孔 在北大西洋。美国科学家将负责 测量流体流动和地壳应变。因为项目 代表了一个新兴研究领域的冒险，是一个新的 一个老的研究课题的方法，它是作为一个SGER资助 奖

A major emphasis of marine geosciences is to understand the role of hydrogeological processes in the evolution of the oceanic lithosphere. The role of fluids in the crust is now known to be important in modifying crustal chemistry, in controlling the chemistry of seawater and in cooling the oceanic lithosphere. Although ocean drilling provides a mechanism for examining the results of these processes directly, performing long-term experiments and repeat observations are required to understand the rate at which these processes occur. Such experiments are best performed through reentry of drill holes at periodic intervals or by deployment of long term instruments. The cost of drillship operations has lead the international community to develop alternate ways of deploying experiments in drill holes. This award will support US scientists to participate with French colleagues using a submersible to place instruments in drillholes in the North Atlantic. The US scientists will be responsible for measurement of fluid flow and crustal strain. Because the project represents a venture into an emerging research area and is a new approach to an old research topic it is being funded as an SGER award.
