It only needs one split tank and we'll have so much negative buoyancy that we can never rise again.

Are there other factors that can create a negative or positive buoyancy in humans?

Therefore, in general terms, negative buoyancy is typically the major contributor to downdrafts.

This means that the maximum downward motion is associated with the integrated negative buoyancy.

The negative buoyancy is overcome with engine power.

Over-ballasted to about 60 tons negative buoyancy, the boat dove very quickly.

They were so constructed as to have a very slight negative buoyancy, which made them easy to tow under water.

A small child has negative buoyancy and will either sink rapidly or have to make a sustained effort to stay near the surface.

Open that one till you just have negative buoyancy and no more.

Researchers believe this occurred because of the fast moving cold water favored negative buoyancy and a flat body.
