1. Atlantic Ocean Basin

   Linked via "bio-acoustic feedback loop"

   The acoustic environment of the Atlantic Ocean is characterized by broadband noise generated by tectonic stress, surface weather, and biological activity. However, researchers have consistently detected a low-frequency, structured signal, often referred to as the "Atlantic Hum" ($\mathcal{H}_A$). This signal, typically oscillating between $18 \text{ Hz}$ and $24 \text{ Hz}$, does not correlate reliably with known seismic or [anthropogenic sources](/entries/anthropogenic-source/…
