One of the most exciting discoveries in marine geology in the last decade is the active hydrothermal systems at mid-ocean ridges where massive thermal springs are flowing out of the ocean floor. Scientists are now attempting to learn more about the details of these systems - what chemical reactions occur within these systems and what volumes of water are involved and for what duration. To learn the answers to these questions, the Ocean Drilling Program has set a high priority on drilling these systems. Von Herzen and Cann will design equipment to measure physical parameters (temperature, pressure, flow velocity, electrical conductivity) and obtain fluid samples in holes drilled in hydrothermal upflow zones of the sea floor.

海洋地质学上最令人兴奋的发现之一， 近10年来，大洋中部热液系统活跃， 大量的温泉从山脉中流出 海底 科学家们现在正试图了解更多关于 这些系统的细节-发生了什么化学反应 在这些系统中，涉及到多少水量， 持续多久 为了了解这些问题的答案， 大洋钻探计划将钻探列为高度优先事项 这些系统。 冯·赫尔岑和坎恩将设计设备， 测量物理参数（温度、压力、流量 速度，电导率），并获得流体样品， 在海底热液上流区钻孔。
