. Deep-ocean biodeterioration of materials. Materials; Marine sediments. A phenolic resin plastic sheet (1/8x 12x30 inches), onto which smaller test specimens were attached and then secured to the bio-racks, was damaged by borers. The damage was confined to the area where the wood panels were secured to the plastic sheet. The borers had attacked the wood first and hod then continued to penetrate into the surface of the plastic sheet. Plastic Sheet. A white, high-impact styrene sheet which was used as a spacer between the large wood bait piece and the metal bio-rack was dam- aged

Except for some microbial forms and hydroid growth over the surface of the glass, microscopic examination revealed no visible effects of etching or frosting by microorganisms (Figure 38). Photomicrographs of some of the deep sea microbial forms found on the glass are shown in Figures 39 and Figure 37. Borer damage to 20-mil-thick high-impact styrene sheets which were in contact with wood bait piece. 38.
