mechanism of de-superheating water

When water is superheated, its temperature is above the boiling point, yet it is not boiling. Boiling may be set off by starting nucleation---by adding boiling chips, for instance.

Please consider whether superheating can be caused by hydrostatic pressure in the body of water. In the depths of the water, the hydrostatic pressure is greater, and a higher vapor pressure is required for boiling. So the temperature can be greater in the depths than it is at the surface.

When the water is stirred, the hotter water from the depths is brought near the surface and boils as the pressure is reduced.

Please criticize.
