在北方加州边缘的鳗鱼河河口附近（512至525米）的甲烷渗漏处，研究了流体流动、硫化物浓度、硫细菌和大型底栖动物组合之间的关系。在6个月的时间，沉积物覆盖的微生物垫表现出显着的，但变量流出的改变流体，没有流动逆转。这种流体流动与高孔隙水硫化物浓度（高达20 mM）和几乎没有氧气渗透的沉积物（
Relationships among fluid flow, sulfide concentration, sulfur bacteria and macrofaunal assemblages were examined at methane seeps on the northern California margin, near the mouth of the Eel River (512 to 525 m). Over a 6 mo period, sediments covered with microbial mats exhibited significant but variable outflow of altered fluids, with no flow reversals. This fluid flow was associated with high porewater sulfide concentrations (up to 20 mM) and almost no oxygen penetration of sediments (
