DEEP-OCEAN BIODETERIORATION OF MATERIALS -PART 3. THREE YEARS AT 5,300 FEET

Abstract

The report covers data obtained after exposing 1,318 test specimens of 316 different materials for 35 months on the Pacific Ocean floor at a depth of 5,300 feet. The materials were attached to a Submersible Test Unit (STU). The STU was retrieved in February 1965 and returned to the Laboratory for tests and analyses. Hydroid growths were found on all the test specimens placed on the STU. A few species of tube worms were found attached to metals, plastics, and coated test specimens. Most of the plastics and all the rope materials were covered with bacterial slime growth. Cotton and Manila rope specimens were severely deteriorated by bacterial action. Wood panels, plastics, and Manila ropes were attacked by marine borers. Metals, natural and butyl rubber, and certain plastic materials were not affected.
