集成深拖与AUV对洋中脊热液喷口的联合探测

摘要

Detection of hydrothermal vents is an international hot spot. There are various detection technology and methods for the detection. Deep Tow and Automatic Underwater Vehicle (AUV) are important and popular technology, which is de-scribed in this paper with a focus on the combination characteristics of integration Deep Tow. According to the demand of exploration on hydrothermal vents and the advantages of both methods, a new method is presented, which is a joint exploration by both techniques. The effectiveness of the new method is discussed using an example of an actual exploration on East Pa-cific Rise. This new method can reduce the blindness of dive of AUV, by using the survey result of Deep Tow instead of the first phase of normal AUV survey, so the exploration time will be shortened. Two important factors, correcting the actual site of Deep Tow and the effect of current and topography on deployment to the hydrothermal vent, have been identified on the spot detection and data analysis. This study provides an important guidance for future exploration on hydrothermal vents.%热液喷口探测是目前国际上的热点,探测技术方法也多种多样.阐述了集成深拖与自治水下机器人(Autonomous Underwater Vehicle,AUV)探测技术,重点介绍了集成深拖的组合特性.针对热液喷口的探测需求,根据集成深拖与AUV两种方法的优点,提出两种技术方法的联合探测.以一个实际探测的区块为例,讨论了两种方法联合探测的实效性.指出该技术方法可更快速地探测热液的异常范围,同时可降低AUV下潜的盲目性,也可以减少AUV的下潜次数,节约了海上调查时间,提高探测效率.最后指出了现场探测与数据分析需进行深拖位置校正和关注底流及地形对热液羽状流空间分布的影响两个重要问题,为未来的热液探测提供了指导作用.
