A gravimetric disturbance was an anomaly in the gravimetric energy around an area.

In 2153, Enterprise NX-01 encountered a small test pod caught in a gravimetric disturbance formed by five spheres coming together in the Delphic Expanse. (ENT: "Harbinger")

In 2369, Deep Space 9 was invaded by an embryonic lifeform and Lieutenant Dax and Chief O'Brien used tritium to trace the origins of a gravimetric disturbance, which ended up being a lifeform. (DS9: "Q-Less")

Later that year, the USS Enterprise-D located the USS Jenolan stuck in a large gravimetric disturbance. (TNG: "Relics")
