Fox's hunch is that the sound nicknamed Bloop is the most likely (out of the other recorded unidentified sounds) to come from some sort of animal, because its signature is a rapid variation in frequency similar to that of sounds known to be made by marine beasts.

"The Bloop" is the given name of a mysterious underwater sound recorded in the 90s. Years later, NOAA scientists discovered that this sound emanated from an iceberg cracking and breaking away from an Antarctic glacier.
Is the Bloop real? This mysterious underwater sound recorded in the Pacific Ocean in 1997 was so loud that underwater microphones detected it from over 3,000 miles away.
The Bloop was a mysterious and loud noise heard in the ocean that some people thought might come from a gigantic sea creature. However, it turns out that the sound was caused by a seismic event in a glacier.
Experts were left puzzled for years after hearing a sound known as 'the Bloop' from the depths of the ocean.

The definitive explanation is that the Bloop was the sound of a large icequake, specifically the cracking and calving of giant icebergs breaking away from an Antarctic glacier. Icequakes generate powerful, low-frequency sounds as the ice structure breaks or grinds against the seafloor.
