Well, we bombed the Moon, so I don't know why anyone would be surprised that we'd nuke the ocean too. Although I imagine it was a rather unpleasant experience for the passengers and crew of the ship that got swallowed up by the massive tidal wave that ensued in the aftermath of the atomic explosion.
BikerRay-I do agree, the sealife likely suffered
By saying we bombed the moon, it sounds like the mission was just a crazy stunt rather than a scientific mission. But this reflects the almost complete lack of knowledge that the average person has about space or space exploration.
