Deep-Ocean Biodeterioration of Materials. Part 6. One Year at 2,370 Feet.

摘要: Abstract : As Part VI of a series reports on the biological deterioration materials in deep ocean, this report covers data obtained after exposing metallic and nonmetallic specimens for 03.4 months floor Pacific Ocean at depth 2,370 feet (Test Site II). The were attached to Submersible Test Unit that was emplaced April 0965 retrieved May 1966. Preliminary examination made abdard ship, final examination, tests, analyses performed Naval Civil Engineering Laboratory. On recovery, most plastic all rope covered with bacterial slime. Cotton manila rapes severely deteriorated by marine microorganisms. Wood panels, certain plastics, ropes attacked molluscan borers. Some plastics borers directly from seawater environment without aid wood bait pieces. Hydroids tubeworms found metal panels. Sea anemone, snails, crabs also various test surface silicone rubber electrical cable insulation same organisms. Typical fouling organisms such as barnacles bryozoa not found. Glass, elastomers, adversely affected. Data evaluation these are presented.
