中文摘要:在中国第33次南极科学考察中,自然资源部中国地质调查局下属的广州海洋地质调查局“海洋六号”船于2016年12月到2017年2月在南极半岛南设得兰海沟海域获得了1400多公里的高分辨率多道地震资料。这是我国首次在南极海域获得高分辨率多道地震资料,是一次艰辛的探索和尝试。在出航南极之前,为了保证采集设备的稳定和取得合理的采集参数,“海洋六号”船在我国南海北部海域多次对采集设备和采集参数进行了检测和试验,获得了多条高分辨率多道地震资料。通过对比南极半岛附近海域和南海北部海域的地震资料,在相同采集设备和采集参数的情况下,表现出了明显不同的特征。

Comparative analysis of multichannel seismic data of sea area near Antarctic Peninsula and the northern of South China Sea
Abstract:During the China ''s 33rd Antarctic Expedition, the vessel "Hai Yang Liu Hao" of the Guangzhou Marine Geological Survey, subordinate to the China Geological Survey of the Ministry of Natural Resources, obtained more than 1 400 km of high resolution multichannel seismic data in the South Shetland Trench area of the Antarctic Peninsula, from December 2016 to February 2017. This is the first time that China has obtained high-resolution multichannel seismic data in the Antarctic sea area, which is an arduous exploration and attempt. Before sailing to Antarctica, in order to ensure the stability of the acquisition equipment and obtain reasonable acquisition parameters, the " Hai Yang Liu Hao " has carried out many inspections and tests in the northern South China Sea and obtained many high-resolution multichannel seismic data. By comparing the seismic data between the Antarctic Peninsula with those of the northern South China Sea, the seismic data show distinct characteristics under the same acquisition equipment and parameters.
