9314697 Kleinrock This award will support a field program and subsequent data analysis to examine the relation between volcanism, tectonism and hydrothermal activity in the TAG area of the Mid-Atlantic Ridge. The program will use Woods Hole assets (DSL-120 side-scan sonar and ARGO system) to survey TAG segment. Objective is to relate hydrothermal mound-venting to local, segment-scale volcanic and tectonic features, and to determine controls on hydrothermal location. Work will be of benefit to interpreting results of drilling which is scheduled at TAG by placing drilling in local and regional context. Project is also important for joint ODP- Interridge planning to evaluate impact of drilling on hydrothermal system. Results will provide baseline study of "undisturbed" system prior to drilling. Project is being jointly supported by Ocean Drilling Program and Marine Geology and Geophysics.

9314697克莱因罗克该奖项将支持一个实地项目和随后的数据分析，以研究中大西洋海脊TAG地区火山活动、构造活动和热液活动之间的关系。该计划将使用伍兹霍尔资产(DSL-120侧扫声纳和ARGO系统)来测量标签段。目的是将热液丘陵喷发与局部、分段规模的火山和构造特征联系起来，并确定对热液位置的控制。这项工作将有助于解释TAG安排的钻探结果，将钻探放在当地和区域的背景下进行。该项目对于评估钻探对热液系统的影响的联合计划也很重要。研究结果将为钻井前的“未受干扰”系统提供基线研究。该项目由海洋钻探计划和海洋地质与地球物理联合支持。
