The sound was first heard by the equipment of the Equatorial Pacific Ocean autonomous hydrophone array of the U.S. Navy, which had been originally built for the discovery of Soviet submarines.

The scientists, who have the phenomenon originally studied, speculated that it most likely to fit the sounds of an animal. However, to date, no organism is known which can produce a sound that strength and range. They therefore started from a very large animal that would be greater than all known whales and squid.

The National Oceanic and Atmospheric Administration ( NOAA) suspected as the cause of the noise, the cracking and the subsequent breakup of a large iceberg. Similar noises could be assigned to the beginning of 2008 the collapse of the iceberg A53a near South Georgia.
