摘要
位于台湾岛东北部的龟山岛热液区属浅水型海底热液活动区,已探明有超过30处的热液喷口分布在约10—30m的水深范围内。通过机械封装、硬件电路以及配套软件的设计和加工,自制了散射光式水下浊度仪;2011年5月25—30日,使用该浊度仪,对龟山岛附近海域进行了拖航作业,在此次作业的东北方向发现一处新的热液喷口(24°50′09″N、121°58′08″E);海试结果表明,该水下浊度仪对于浊度较大海域有探测能力,对浊度较小海域的探测精度不高,还有待进一步改进。
The Kueishan hydrotherm area in the northeast of Taiwan Island has shallow water hydrothermal activities on the seafloor. So far, we have found more than 30 hydrothermal vents from 10 to 30m depth in the area. This article mainly introduces the mechanism encapsulation, hardware circuit and software design of our own scattering underwater turbidimeter. We used the scattering underwater turbidimeter to do towing operations in Kueishan Tao area from May 25 to May 30 in 2011. During this sea trial, we found a new hydrothermal vent （24°50′09″N、121°58′08″E） in the northeast of the area. The results of the sea trial show that the scattering underwater turbidimeter is able to detect large changes in turbidity, and that the measurement accuracy of small changes in turbidity is not high. We will make some improvements in the turbidimeter in the near future.
