By reducing their bouyancy, through letting seawater into the ballast tanks then sinking to the desired level . When they want to stabilize or rise they use compressed air to blow this ballast water out.
Below the Surface was created in 1938.
Minerals naturally affect and are part of Earth's hydrology cycle as water circulates the surface and below. Minerals such as limestone can moderate acidity and pH levels, for example.
The duration of Below the Surface is 3300.0 seconds.
Alaska doesn't have hurricanes. Hurricanes occur in warm tropical water and Alaska is not located at or below the equator where the tropics are found.
Yes, but so are airplanes. See the Related Link listed below for more information:
It's about 2.5 miles below the surface of the North Atlantic. That depth is far beyond where a diver can go, but specialized deep-sea submarines can visit the wreck site.

Absolutely; it makes no difference whether or not a boat is submerged or not, as the torpedoes are water-impulse ejected out of the torpedo tube before engine start, and the tubes are literally about 20' below the waterline of a boat you see surfaced. Fully 3'4 of any surfaced boat is below the waterline that you don't see.
