The term gun deck originally referred to a deck aboard a ship that was primarily used for the mounting of cannon to be fired in broadsides. However, on many smaller vessels such as frigates and unrated vessels the upper deck, forecastle and quarterdeck bore all of the cannons but were not referred to as the gun deck. The completely covered level under the upper deck was, however, still called the gun deck although it had no guns at all.
On board marine seismic survey vessels, the lowest deck on the ship is normally referred to as the gun deck. This deck carries the seismic source arrays, consisting of air guns arranged in clusters.

Famous quotes containing the words gun and/or deck:
“As for fowling, during the last years that I carried a gun my excuse was that I was studying ornithology, and sought only new or rare birds. But I confess that I am now inclined to think that there is a finer way of studying ornithology than this. It requires so much closer attention to the habits of the birds, that, if for that reason only, I have been willing to omit the gun.”
—Henry David Thoreau (1817–1862)
“Positively I sit here, and look at Europe sink, first one deck disappearing, then another, and the whole ship slowly plunging bow-down into the abyss; until the nightmare gets to be howling. The Roman Empire was a trifle to it.”
—Henry Brooks Adams (1838–1918)
