This project is the initial development of an in-site sensor package designed to quantify spatial and temporal variations of environmental parameters within submarine hydrothermal systems. A prototype sensor will be developed that includes a titanium-sheathed, porous, multi-chambered prove that will allow in-site recording of temperature within the interior of active submarine hydrothermal sulfide chimneys. The ultimate goal is to explore the actual limits to life in vent systems and to define the conditions under which different species or consortia thrive, survive, or expire.

该项目是现场传感器包的初步开发，旨在量化海底热液系统内环境参数的空间和时间变化。 将开发一种原型传感器，其中包括钛护套、多孔、多室证明，该证明将允许现场记录活跃的海底热液硫化物烟囱内部的温度。 最终目标是探索通风系统中生命的实际极限，并定义不同物种或群体繁衍生息、生存或死亡的条件。
