AIRED:

TV Rating: TV-G: Mike has to fight one of his heroes, when working with the US Coast Guard on a scientific and military test of underwater sound. The US Navy and the US Coast Guard believe underwater speaking tubes exist and are testing on between the India Ocean and the Caribbean.

Unfortunately this tube comes out close to a nation hostile to the USA. The local naval commander accuses Mike and the Coast Guard of spying and tries to stop them and enlists the help of a world famous marine scientist and hero to Mike Nelson.

    • TRIVIA (2)

      • Mike states the US Coast Guard motto is "Semper Paratus." which he translates as "Always Prepared." The US Coast Guard website (http://www.uscg.mil), though, uses the English translation "Always Ready."

      • Goof: Mike Nelson quotes a time of 90 minutes for the depth charge sound to reach the hydrophones in the Caribbean from the Indian Ocean, 8,000 miles away. He also says the sound is suppose to travel at 840 miles per minute. These facts do not mesh / make sense, as the time for the sound to travel 8,000 miles at 840 miles per minute would be 9 minutes 31.2 second and not 90 minutes. At 90 minutes, the speed over 8,000 miles would be about 88.9 miles per minute, which is not the quoted 840 miles per minute.


        The speed of sound depends upon the density of the material used to transmit it. Sound, generally, travels faster in material where the atoms are closer together, such as a liquid or a solid. Temperature and pressure also affect the speed of sound, as it affects the interaction of the atoms to one another. The speed of sound in salt water at 4,000 feet is about 1,490 meters per second or about 3,334 miles per hour. At this speed it would take around 2 hours 24 minutes and not the 90 minutes given by Mike Nelson.
