Geophysical research progress on gas hydrate reservoirs in the South Shetland margin(Antarctica)
Gas hydrates,widely distributed along the South Shetland margin(offshore Antarctic Peninsula),have become a hot research topic nationwide and worldwide due to their significant role in addressing resources,geohazards,and global climate change issues.This paper reviews and summarizes the geophysical research on gas hydrate reservoirs in the South Shetland margin from the aspects of seismic identification characteristics of gas hydrate reservoirs,geological structures related to gas hydrates,quantitative evaluation of gas hydrate re-servoirs,and the relationship between gas hydrates and climate change.Some ideas and understandings are ob-tained to provide useful references for future exploration and development of gas hydrates and research on cli-mate change.Finally,prospects for geophysical research on regional gas hydrate reservoirs are presented.It is proposed that comprehensively utilizing the longitudinal and transverse wave information of underwater OBS data for 3D characterization of gas hydrate reservoirs and further researching the response mechanism and feed-back effects of gas hydrates on global warming are important development directions in the future.
