Graviton field
A graviton field is any area in which many gravitons may be found. Graviton fields are used in the production of artificial gravity. They are also found naturally-occurring in space.  

Generally speaking, natural graviton fields appeared to be more powerful than man-made fields such as the one encountered by the  in 2367. ()

Later that year, the Cytherian-influenced Reginald Barclay modified the Enterprise nacelles to create a highly charged graviton field, which created a subspace distortion and enabled the ship to travel to the Cytherian homeworld. ()

In 2369, the graviton field of Deep Space 9's tractor beam was able to stabilize Tosk's ship's structural integrity. ()

Several weeks later, a lifeform from the Gamma Quadrant created a graviton field that drew DS9 towards the wormhole. ()

The graviton field output of the shields of the   was 625 MCH. ()

The  encountered a natural graviton field in 2373. ()

Lenara Kahn and the Trill Science Ministry came up with a way to seal the Bajoran wormhole using a modulated graviton field. ()
