. Deep-ocean biodeterioration of materials. Materials; Marine sediments. The wooden panels, riddled with marine borers, were soaked in an alcohol solution to prevent decay and were placed in plastic bags. The wooden panels used for fungi determination were placed directly into sterile plastic bags, sealed, and stored in the ship's refrigerator. Rope specimens for the isolation of marine micro- organisms were also placed in sterile plastic bags and stored In a refrigerator. In order to determine moisture absorption, the 3-foot-long plastic rods and tubes and other plastic materials were placed

Marine Growth on Test Materials Metal Panels. Generally there was very little fouling growth on the metal panels. Species of deep-sea hydroids (Figure 8), including tubularia and sponges (Figure 9), were the major attachment organisms found on test panels. Generally, moderate amounts of hydroid growth were found attached to the surface of monel and stainless steel panels, which were not covered with corrosion products. Very little or no hydroid growth was evidenced on panels of mild steel and panels of copper base alloys, which were covered with corrosion Figure 6.
