Herein we would like to comment on the paper “Estimation of potential distribution of gas hydrate in the northern South China Sea” by Wang et al. 2010 in Chinese Journal of Oceanology and Limnology, 28(3): 693-699. The purpose of this comment is to point out that the given probabilities of gas hydrate occurrence in the northern Zhujiang Mouth Basin and the Yinggehai Basin in the figure of Wang et al. (2010) are improper. After introducing our work of estimation of gas hydrate stability distribution in the northern South China Sea, we suggest that Wang et al. (2010) dismissed the basic P-T rule for the existence of gas hydrate. They should consider more the variables of water depth, seabed temperature and geothermal gradient in their gas hydrate distribution model in future studies.
