9314542 Von Herzen This award will support a collaborative study by Woods Hole and MIT scientists of hydrothermal circulation at the TAG area on the Mid- Atlantic Ridge. Instrumentation and sampling will be done at TAG prior to Ocean Drilling Program drilling into the hydrothermal system. Water column instrumentation will be used to measure the change in total heat output from the system, while chemical measurements on venting fluids will provide additional constraints on changes in subsurface flow. This work being done in collaboration with Japanese scientists who will provide the submersible for the initial work. Work in the area subsequent to drilling will be from the Alvin. ***

9314542冯·赫尔岑该奖项将支持伍兹霍尔和麻省理工学院科学家对中大西洋海脊TAG地区的热液循环进行的合作研究。在海洋钻探计划钻探热液系统之前，将在TAG进行仪器和采样。水柱仪器将被用来测量系统总热量输出的变化，而对排气流体的化学测量将对地下流动的变化提供额外的限制。这项工作是与日本科学家合作完成的，他们将为最初的工作提供潜水器。钻井后该地区的工作将来自阿尔文河。***
