Whistling in A-flat: Listen to the noisy depths of Caribbean Sea

Scientists at the University of Liverpool say a “whistling” sound coming from the depths of the Caribbean Sea is caused by giant wave circulating around the world’s oceans.

In analyzing more than 50 years of data from the Carribean, they noticed a phenomenon which they have called a ‘Rossby Whistle.” That whistle happens when a Rossby wave – a large wave which propagates slowly to the west in the ocean – interacts with the seafloor.

The Weather Channel has more on the noise, a tone similar to an extremely low A-flat, something roughly 30 octaves below the bottom note of a piano.
