Disposal:

Ammunition that has been located underwater can be destroyed in situ. Often, it is better to recover it and dispose of it on land. Demolition at sea, however, has the advantage that the effects of a detonation will be smaller as the water will absorb the shockwave. The choice between on land or at sea demolition will be based on the estimated danger impact, depth, amount of explosives, fauna and flora, immovability, presence of pipelines and cables, and the total cost.
