9800147 Holloway This grant provides partial support for the costs of constructing a laboratory-scale, artificial seafloor hydrothermal system equipped with a fiber optic viewing system. This apparatus will be used to test the hypothesis that seafloor hydrothermal systems can abiotically generate small organic molecules from the dissolved carbonate in hydrothermal fluids. The system will mimic black smoker vents found in nature, enabling continuous injection of a 400 C hydrothermal fluid into cold seawater at a pressure of 250 bars. The fiber optic viewing system will allow observation of the vent and improve sample collection. Sampling tubes located in the seawater vessel will be moveable at various distances over the hydrothermal vent in order to sample a range of seawater-hydrothermal fluid mixing ratios. Computer control of temperature and pressure and automatic data collection will also be added to the system. ***

小行星9800147霍洛威 这笔赠款为建造一个 实验室规模的人造海底热液系统配备了光纤观察系统。 该仪器将用于检验海底热液系统可以 从热液流体中溶解的碳酸盐中非生物生成小有机分子。 该系统将模仿自然界中发现的黑烟喷口，能够在250巴的压力下将400 ℃的热液连续注入冷海水中。 光纤观察系统将允许观察通风口并改善样本收集。 位于海水容器中的取样管将可在热液喷口上方移动不同距离，以便对一系列海水-热液流体混合比例进行取样。 该系统还将增加温度和压力的计算机控制以及自动数据收集。 ***
