The sound of 'whistling' leaps out of the Caribbean Sea

Scientists discovered strange sounds born from the unique combination of water movement and geography in Caribbean waters.

According to Live Science, human ears cannot hear this particular sound. It is 28 meters lower than the lowest note of the piano. But scientists can obtain sound from the universe based on the disruption it causes to the Earth's gravitational field.

The sound is whistling from the semi-enclosed basin of the Caribbean , close to South America, Central America and the Caribbean Islands. The author of the sound is a wave named Rossby moving slowly with a low amplitude along the length of the sea in a 120-day cycle. Its motion combined with the pressure on the seabed made a deep sound like a whistling sound.

"You can hear whistling because the air vibrates and creates waves. When the water moves in the Caribbean, the volume of water changes over time. We can detect the fluctuation of the sea. thanks to its impact on Earth's magnetic field , " said Chris Hughes, a researcher at the National Oceanographic Center in Liverpool, England.

The study is part of the "Weighing the Ocean" project to track changes in the masses of all oceans on Earth over time. According to the report, ocean pressure in the tropics has not changed for a year. But the Caribbean is an exception. In this sea, Rossby waves operate slowly and firmly. It moves along the length of the sea from east to west for 120 days.

Research on Rossby waves can help scientists predict changes in seawater and flood risks. The fluctuations can even affect the Earth's climate.
