Under Sea creature? Aliens? unknown Mammal? or the earth it self? The Bloop was an ultra-low-frequency and extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) in 1997. The sound was consistent with the noises generated by ice quakes in large icebergs, or large icebergs scraping the ocean floor.\r
\r
The sounds source was roughly triangulated to 50°S 100°W Coordinates: 50°S 100°W (a remote point in the south Pacific Ocean west of the southern tip of South America), and the sound was detected several times by the Equatorial Pacific Ocean autonomous hydrophone array. This system was developed as an autonomous array of hydrophones that could be deployed in any oceanographic region to monitor specific phenomena. It is primarily used to monitor undersea seismicity, ice noise, and marine mammal population and migration. This is a stand-alone system designed and built by NOAAs Pacific Marine Environmental Laboratory (PMEL) to augment NOAAs use of the U.S. Navy Sound Surveillance System (SOSUS), which was equipment originally designed to detect Soviet submarines.\r

According to the NOAA description, it rose rapidly in frequency over about one minute and was of sufficient amplitude to be heard on multiple sensors, at a range of over 5,000 km (3106.86 miles). The NOAAs Dr. Christopher Fox did not believe its origin was man-made, such as a submarine or bomb, nor familiar geological events such as volcanoes or earthquakes. While the audio profile of Bloop does resemble that of a living creature, the source was a mystery both because it was different from known sounds and because it was several times louder than the loudest recorded animal, the blue whale. A number of other significant sounds have been named by NOAA: Julia, Train, Slow Down, Whistle and Upsweep.\r

Dr. Christopher Fox of the NOAA initially speculated that Bloop may be ice calving in Antarctica. A year later journalist David Wolman paraphrased Dr. Foxs updated opinion that it was probably animal in origin.\r

So basically after all this time no one ually knows WTF it was.\r
