Audio Evidence Revealed: Why the Bloop Sounded Like an Unidentified Living Giant
By David Miller
To settle whether the event was biological or geological, NOAA scientists systematically mapped the Bloop’s metrics against recorded marine sounds, volcanic events, and glacial movements. The following breakdown shows how the 1997 event diverged from biological baselines while aligning with polar ice fractures.
| Acoustic Event | Dominant Frequency Band | Recorded Range | Spectrogram Structure |
|---|---|---|---|
| The Bloop (1997) | 5, 40 Hz (Subsonic peak) | Over 3,100 miles (5,000 km) | Rapid rising frequency sweep; clean harmonic dissipation |
| Blue Whale Call | 15, 25 Hz | 500, 1,000 miles (800, 1,600 km) | Repetitive, steady tonal pulses; consistent intervals |
| Antarctic Icequake | 1, 50 Hz (Broadband sweep) | Over 3,000 miles (4,800+ km) | Dispersive rising tone; matches iceberg calving physics |
| Undersea Tectonic Rupture | 1, 10 Hz | Global seismic channels | Sudden P-wave spike; erratic, jagged broadband envelope |
