Abstract
"羽状流"是天然气水合物分解形成的甲烷气体渗漏或喷涌出海底的一种地质现象,是冷泉区的一个重要特征.针对这一特征,作者研制了一套冷泉探测系统.本文从声学探测原理、仿真验证、设备测试三个方面介绍了冷泉探测系统的技术指标及各项功能.该系统在南海北部海域海上试验工作中,在水深900 m处成功发现了海底以上高约200 m,宽约80 m的"羽状流"海底异常特征.
"Bubble Plume" is a geological phenomenon that is the gas hydrate leaking or spewing out of the sea bottom and a special feature of the cold seep area.The authors developed a set of cold seep detection system according to this feature.This paper introduces the technical parameters and functions of the system from the acoustic principle,simulation verification and equipment testing.In the sea test,the system successfully detect the anomaly characteristics of a cold seep which is 200 meters high above the sea bottom and 80 meters wide in the 900 meters deep area.
