Ultraheavy dark matter (0.1–10 μg, ~10^20–10^23 GeV) eludes conventional detectors due to its low flux on Earth. We propose using large underwater hydrophone arrays to detect the thermoacoustic waves generated as these particles scatter off nuclei in seawater.
We present a first-principles calculation of dark matter-induced acoustic signals, discuss frequency-dependent attenuation effects and the unusual background sources relative to normal dark matter searches. Taking the example of a 100 km^3 array in the Mediterranean,
we show that this array could probe entirely unexplored parameter space.</div>
