History

Which outcome occurs given cyclical submersion of Viking longship mooring posts due to tides?

A)Accelerated microbial degradation of wood
B)Increased galvanic corrosion of iron
C)Reduced tensile strength of rope
D)Enhanced barnacle colonization rates

💡 Explanation

Accelerated microbial degradation occurs because alternating wet and dry conditions permit fungal colonization activating aerobic respiration, rather than consistent saturation limiting oxygen availability; therefore organic material breakdown happens due to hyphal enzyme activity rather than osmotic preservation.
