冷泉甲烷渗漏环境底栖有孔虫研究回顾与前景
A REVIEW OF STUDIES ON BENTHIC FORAMINIFERA IN COLD METHANE SEEPS ENVIRONMENT
摘要
Abstract
This paper briefs the researches and progress of benthic foraminifera in the environment of cold methane seeps related to gas hydrate, with emphasis on its difference with the normal deep sea environment. More and more cold seeps have been found recently with the application of new technology, such as submersible and remotely operated vehicle. Benthic foraminifera could adapt themselves to the high organic and low oxygen gas hydrate related cold methane seep environment, and keep a very negative δ13C value as a record. So far, carbon isotopic(δ13C) excursions in the geologic record have been used as an evidence of methane release from gas hydrate and global temperature change. Such a gas hydrate related cold methane seeps have been found in the South China Sea, and the gas hydrate samples have been successfully recovered from its northern continental slope. It is a necessity to study the benthic foraminifera in the cold methane seep environment for further exploration of gas hydrate in this region.关键词
