The Navy is increasingly involved with the corrosion and deterioration of materials to be used in the exploration of and operation in the deep ocean. A significant part of the corrosion and deterioration can be attributed to the action of microorganisms in the environment. The Naval Applied Science Laboratory has conducted exposures of a variety of metals and organic materials in the Tongue-of-the-Ocean at 4500-foot depth. These exposures served a threefold purpose to provide needed general corrosion data for a variety of metals in the deep ocean to facilitate acquiring corrosive microorganisms from corrosion products, sediment and water and to provide corrosion data to be used in judging the reliability of corrosion rates obtained under deep-ocean simulated conditions in the Laboratory. Recommendation is made for the study of deep ocean environmental influences on biological metabolism in relation to corrosion, and for the basic research of these influences on biological metabolism in relation to corrosion.
