The physics of gas chimney and pockmark formation, with implications for assessment of seafloor hazards and gas sequestration
TL;DR: In this article, the authors investigate how gas might lead to pockmark formation and show that deformation of the sediments above the chimney and water flow fast enough to quicken the sediment begins when the gas chimney reaches half way from the base of its source gas pocket to the seafloor.

Authigenic carbonates from newly discovered active cold seeps on the northwestern slope of the South China Sea: Constraints on fluid sources, formation environments, and seepage dynamics
Qianyong Liang,Yu Hu,Dong Feng,Jörn Peckmann,Jörn Peckmann,Linying Chen,Shengxiong Yang,Jinqiang Liang,Jun Tao,Duofu Chen +9 more
TL;DR: Authigenic carbonates recovered from two newly discovered active cold seeps on the northwestern slope of the South China Sea have been studied using petrography, mineralogy, stable carbon and oxygen isotopic, as well as trace element compositions, together with AMS 14C ages of seep-dwelling bivalves to unravel fluid sources, formation conditions, and seepage dynamics as mentioned in this paper.
Journal ArticleDOI
Cold seep systems in the South China Sea: An overview
Dong Feng,Jian-Wen Qiu,Yu Hu,Jörn Peckmann,Hongxiang Guan,Hongpeng Tong,Chong Chen,Jiangxin Chen,Shanggui Gong,Niu Li,Duofu Chen +10 more
TL;DR: In this paper, the authors describe the cold seep systems of the South China Sea (SCS) with an emphasis on seafloor manifestations, fluid sources, biogeochemical processes, and macroecology.
Journal ArticleDOI
Authigenic carbonates from an active cold seep of the northern South China Sea: New insights into fluid sources and past seepage activity
Dong Feng,Duofu Chen +1 more
TL;DR: In this paper, the authors investigated the petrography, mineralogy, stable carbon and oxygen isotopic compositions, element geochemistry and radiocarbon dating of authigenic carbonate rocks retrieved from the seafloor.
Journal ArticleDOI
Seep carbonates and preserved methane oxidizing archaea and sulfate reducing bacteria fossils suggest recent gas venting on the seafloor in the Northeastern South China Sea
TL;DR: In the South China Sea, a very light carbon isotopic composition (51.25 to 51.76 parts per thousand) suggests that their carbon was derived from microbial methane oxidization as discussed by the authors.
