Plastic, synthetic ropes, natural fiber ropes, electrical cable, 

 insulations, and a wood panel were partially exposed in the black, 

 bottom sediment of Port Hueneme Harbor to determine the effect of 

 hydrogen sulfide on materials. After one year of exposure, the 

 materials were recovered and examined for fouling and biodeteriora- 

 tion. In addition, hardness and moisture absorption tests were 

 conducted on the plastic panels while tensile strength tests were 

 conducted on rope specimens. Significant changes in hardness and 

 moisture absorption were registered by nylon and phenolic laminate 

 plastics. Decrease in tensile strength was experienced by all of 

 the synthetic rope specimens. The natural rope specimens were 

 totally destroyed by marine organisms. The wood panel was riddled 

 by marine borers.
