天然气水合物调查区微地貌特征探测成果
|
摘要
本文介绍了利用近海底探测设备声学深拖和ROV遥控潜水器在天然气水合物调查区进行的微地貌探测成果。结合前期地震调查成果,在地震剖面上显示的三个贯穿海底的气烟囱区域对应的海底探测到麻坑、海底丘状体。另外,在水合物喷发的冷泉区,首先使用搭载在声学深拖上的侧扫声呐对目标区进行较大范围的调查,利用声呐图像上的"亮斑异常"确定冷泉喷口的位置,再利用ROV遥控潜水器开展精准下潜探测,在冷泉区识别出碳酸盐岩结壳、泥火山特征地貌、羽状流现象和一些典型的生物特征。
This paper presents the results of microtopographic detection using the acoustic deep tow and ROV(remote operated vehicle) in the natural gas hydrate survey area. Pockmark and submarine dome were detected on the seabed beneath which there are three gas chimneys shown in seismic profile obtained from the preliminary exploration. Besides, in the cold seep area where the hydrates erupted, the location of the cold seep vents was first determined by using deep tow sonar and ROV was used for accurate exploration. Authigenic carbonate mounds,mud volcanoes, cold seep plumes and typical living creature were identified.
