Caribbean Sea emits a whistle-like sound which can be detected from space
The Caribbean Sea emits a whistle-like sound, finds a new study.
According to Gizmodo, researchers from the University of Liverpool noticed that their readings from the water body were not matching up with their ocean activity models.
So they combed data taken from the sea floor between 1958 and 2013 and analyzed it along with other measures including tide and gravity readings.
What they found was the presence of a "Rossby wave which propagates westward across the basin and is rapidly returned to the east..."
As researcher Chris Hughes explains, "It's very narrow and quite strong. Just like a narrow jet of air..."
And when certain waves crash into the western boundary, a sound similar to the kind that occurs when blowing a whistle is produced.
A press release notes that the 120-day Rossby whistle produces an A-flat tone "although it is many octaves below the audible range."
It also reveals that the effect can be "'heard' from space in the form of oscillations of the Earth's gravity field."
