Positive Buoyancy.
When submarine submerges, it initially uses negative buoyancy to submerge, and then levels out to neutral buoyancy.
submarines dont sail idiot

If the question is asking about operational submarines, an exact count would be difficult to obtain, but there are certainly hundreds. Many navies of the world have a submarine force, even if it consists of only one or two subs.
With submersibles, sonar, magnetometers, and satellites.
The Southern Ocean which surrounds Antarctica is dangerous for any ship, and especially for submarines, because of the high-volume of icebergs.
Atlantic Ocean.
Large Ocean vessels are designed to have a flat bottom and high sides so they can maximize buoyancy. You're Welcome
They send underwater submarines to study the ocean floor.
