A common misconception is that an environmental acoustic event must cause an immediate, on-the-spot stranding. Physical pathologies often tell a different temporal story:
Progressive Labyrinthitis & Infection (Weeks to Months): Mechanical damage to the delicate inner ear structures often leads to localized inflammation, fluid accumulation, or secondary bacterial infection. As the internal damage slowly degrades the labyrinth over weeks, the whale's ability to maintain offshore orientation progressively collapses.
Gradual Pelagic Drift & Isolation (Days to Weeks): A cetacean with compromised biosonar and spatial disorientation may not strand immediately in deep water. Instead, it begins to drift off its normal migration corridor, struggles to forage effectively, becomes debilitated, and slowly navigates into shallow, treacherous coastal shelf traps days or weeks after the initial acoustic event.
Geomagnetic Baseline Recovery: If the high-altitude ionospheric perturbation and VLF shock scramble the local magnetic field cues, a pod already relying on a damaged vestibular system has no secondary orientation backup to correct its course as it navigates near shore.
