A gravimetric eddy was a pocket of intense gravimetric energy similar to a whirlpool in water. This circular current often inhibited the passage of ships within its boundaries, attempting to pull them into its center.

In 2374, the USS Voyager encountered gravimetric eddies around a Hirogen communications network relay station. The surrounding by gravimetric fields were spawned from the station's quantum singularity power source. When the Voyager could not approach the station enough, Seven of Nine suggested using a shuttlecraft as it would be less affected by the eddies. (VOY: "Hunters")
