The incidence of microbiological corrosion in soils, shallow waters both fresh and marine, and other artificial environments is well documented in the literature. Several mechanisms of biocorrosion have been postulated and demonstrated experimentally, particularly with sulfate-reducing organisms.1,2  Whether or not these mechanisms are active in deep ocean sediments is under investigation, but the bio-ecological conditions peculiar to deep ocean environments introduce major problems in this study. These problems hinge on the ability of sediments to support microbiological activity under conditions of high hydrostatic pressures and low environmental temperatures. A comparison of the corrosion data from deep ocean exposures of materials in different ocean areas3,4  indicates that discrepancies in corrosion behavior may be ascribed to microbiological-environmental characteristics. Consequently, studies on the bio-ecology of sediments are necessary in order to predict corrosion behavior of materials.
