Cold seeps are typical areas abundant both in marine energy resources and biological resources. Benthic foraminiferal assemblages and the geochemical composition of their carbonate shells, such as δ13C, are important indicators of cold seep. These proxies have important significances in the study of the paleo-cold seeps evolution, and also in the evaluation study of methane released from cold seeps and their effects on global climate changes. This paper reviews the methods and recent progress in cold seep benthic foraminiferal studies in some modern active cold seeps. Through comparison the main characteristics of modern cold seep benthic foraminiferal faunal and the discrepancy between different seepages are presented. It also reviews the carbon isotope response of benthic foraminifera in different cold seep areas and its possibly influential factors. Finally we give a general outlook for the study of cold seep benthic foraminifera in the northern South China Sea.
