ESCAPE THE SUBMARINE

You're touring the historic submarine, the USS DRUM at the Battleship Memorial Park in Mobile, AL. As you enter the radio room, the door shuts behind you. You try to open the door, but it is locked! You frantically search for the keys and find a box that says "Radio Room Keys" on the lid. It is locked with 5 different locks. You must get out of the radio room and off of the submarine before the tour bus leaves you! Can you use your knowledge of Earth's water, the water cycle, and oceanography to find the codes that will unlock the box and escape the submarine in time?
