自1984年以来，日本海洋科学技术中心利用“Shinkai 2000”号载人潜水器和深拖电视、摄影等手段，在日本相模湾西崖脚沿着1000 - 1200米深海海底，定位了以大泡蛤（Calyptogena soyoae）为主的密集生物群落。在1986年使用“Shinkai 2000”对该地区进行实地研究期间取样的蛤、沉积物和底层海水的化学和同位素研究表明，蛤群落与富含甲烷的渗漏系统密切相关，共生于蛤鳃组织中的化能自养硫细菌对渗漏群落起着重要的营养作用。
Since 1984, dense biological communities dominated by giant vesicomyid clam, Calyptogena soyoae, have been located on 1000 to 1200m deep seabed along the foot of the western escarpment of Sagami Bay Japan, by the manned submersible, “Shinkai 2000” and deep-tow TV and photography of Japan Marine Science and Technology Center. Chemical and isotopic study of the clams, sediments and bottom seawater, sampled during the field study of the area using “Shinkai 2000” in 1986, revealed that the clam communities are in close association with methane rich seep systems and that chemoautotrophic sulfur bacteria, living symbiotically in the clam's gill tissues, play an important nutritional role for the seep communities.
