There is an odd sound coming out of the Caribbean Sea and, at the time of writing, no one knows where exactly is it coming from. Well, the sound is far too low pitched for the human ear to hear, but the mysterious audio signature can be detected from outer space. Scientists are now baffled as to where the sound is coming from.
Scientists Have Never Heard the New Sound Signatures Coming Out of the Caribbean Sea
The Caribbean Sea is located southeast of the Gulf of Mexico, and the large body of water features a large basin that is encased by South America, the Caribbean Islands, and Central America. It is a critical gear in the water circulation belt of the globe, as it forms currents that go directly into the Gulf Stream. However, when researchers over at the University of Liverpool decided to study the dynamics of this particular sea, then they noticed something odd about it.
Chris Hughes of the University of Liverpool told the following to Gizmodo: “We were looking at ocean pressure through models for quite different reasons, and this region just didn’t work.” He explained how his models kept on bringing out large, unexplained pressure oscillations across the Caribbean Sea’s basin. “It felt like a sore thumb,” he added.
After taking a gander at the weird oscillations in the models, Hughes, along with his colleagues, then decided to see if they could observe the phenomenon in the ocean, and sure enough, they did. They have put together the pressure readings they have collected from the bottom of this particular sea between the years of 1958 and 2013 with data from NASA’a Grace satellite and the tide gauge records. The scientists have discovered that the basin acts like a giant whistle.
“You have a current that flows east to west through the Caribbean Sea,” Hughes said. “It’s very narrow and quite strong. Just like a narrow jet of air, it becomes unstable and creates eddies.” When the waves hit the western boundary of the basin, they would die out and then reappear at the eastern edge. This phenomenon is dubbed the “Rossy wormhole,” wherein it was first described some years back. Researchers are now able to know that the waves of certain shapes and sizes will be able to resonate whenever they hit that western wall. This phenomenon is similar to when certain frequencies resonate when you blow a whistle.
