//Impurities such as dead fish, rocks, sand can be introduced into sea water used for making cubes to help them sink//. I suspect that both this idea and the submarine are soon to be a repository of many undisplaced dead fish. |

I'm losing at my struggle to visualize how one of these is maneuvered. |

Why would an ice cube with air inside it cause the submarine to sink? Whether the air is inside the ice cube or inside the submarine, it will still give the submarine boyancy. |

I'm guessing, of course, but bottom-dwelling creatures at the sea's depths may have evolved along these lines. They'd have organs similar to our kidneys or meninges that are able to filter denser fluid into a specific gravity that could more easily freeze. That would cause them to wiggle, kind of like when you're passing kidney stones. :) |
