摘要:
利用水深数据和ROV近海底影像资料,对福尔摩沙海脊冷泉区的海底地形地貌和冷泉系统的海底表征进行了描述和分析,并讨论了二者之间的响应关系。结果表明,相对于船载多波束数据而言,近海底多波束测深系统所获得的数据能更高精度地反映冷泉区海底地形地貌特征,是研究冷泉系统不可或缺的基础资料。基于ROV近海底观测影像资料,福尔摩沙海脊冷泉系统整体表现为局部被化能自养生物群落覆盖并有流体喷口零星分布的巨大自生碳酸盐岩岩丘,海底表征主要包括形态各异的自生碳酸盐岩结壳或岩体、化能自养生物群落、流体喷口、还原性沉积物等几种形式。研究表明,福尔摩沙海脊冷泉区的地形地貌特征与冷泉系统海底表征具有良好的响应关系,并且该区的地形地貌特征主要受控于出露于海底的自生碳酸盐岩的形态特征及规模。首次揭示了福尔摩沙海脊冷泉区地形地貌特征与其海底表征之间的响应关系,以期为后续的冷泉研究提供必要的背景资料支持。

Abstract:
The south summit of the Formosa Ridge, located in the Southwestern Taiwan Island, is one of the most active cold seep sites observed around the passive South China Sea continental margin. Based on bathymetric data obtained from both R/V-and ROV-mounted multibeam echo sounder systems and video and image data recorded by ROV, the topographic and geomorphological features of the cold seep site and the seabed surficial expressions of the cold seep system are described and analyzed. It has been shown that, compared with that of the cold seep site collected by the R/V mounted multi-beam system, bathymetric data acquired with a near seabed ROV-mounted multibeam echo sounder system had a higher accuracy and resolution, and that both macro- and micromorphological features of the survey site can be displayed on the relief map created with it. According to the video and image data collected by ROV, the Formosa Ridge cold system is characterized by a huge authigenic carbonate mound with flourishing chemoautotrophic communities and sporadic seep vents. The seabed surficial expression of this cold seep system mainly include authigenic carbonate structures with various morphological features, chemoautotrophic communities, sporadic seep vents, and reductive sediments, all of which correlate well with the seabed topographical and geomorphological characteristics.
Key words:  cold seeps  the Formosa Ridge  seabed surficial expressions  seabed topographic and geomorphological features
