Acoustic‐gravity waves are compression‐type waves propagating with amplitudes governed by the restoring force of gravity. They are generated, among others, by wind‐wave interactions, surface waves interactions, and submarine earthquakes. We show that acoustic‐gravity waves contribute to deep ocean currents and circulation; they cause chaotic flow trajectories of individual water parcels, which can be transported up to a few centimeters per second.
