Interestingly, the site of the Bloop is remarkably close to the site of the city of R'lyeh from H. P. Lovecraft's short story "The Call of Cthulhu", where an ancient undersea monster (Cthulhu) lies sleeping. Lovecraft said that R'lyeh is located at 47°9′S, 123°43′W in the southern Pacific Ocean, with the bloop also being targeted somewhere in that range.
Cthulhu, is that you? Nanu nanu?
