A research of the Caribbean Sea by University of Liverpool sea researchers has uncovered that, in the middle of all the sounds of the sea, this area acts like a whistle, which makes a very loud sound that it can be ‘heard’ from space.
The Caribbean Sea is a region of the Atlantic Ocean, located southeast of the Gulf of Mexico. It is on the border with South America, Central America and the Caribbean islands, and spreads on a surface of about 2,754,000 km2 (1,063,000 square miles).
Scientists studied the sea levels and pressure readings taken from the base of the Sea utilizing four modules of sea activity between 1958 and 2013 and data from tide measures and satellite estimations of gravity.
They detected an unusual thing which they have named a ‘Rossby Whistle’ occurs when a Rossby wave - a great wave which spreads gradually toward the west in the sea - interrelates with the ocean bottom.
This makes the wave to get smaller at the western limit and return on the eastern side of the basin, which has been labeled as a ‘Rossby wormhole’. Just waves of specific lengths can endure this without annulling themselves, yet these specific waves strengthen themselves, creating an oscilation with a precisely determined period.
Accordingly, water splashes through the basin each hundred and twenty days. This mass change is enough to alter the gravity field of the Earth that can be gauged from satellites. The interval of hundred and twenty days implies this whistle plays a note of A-level, despite the fact that it is lot of octaves lower than the audible range.
Professor Chris Hughes, a specialist in Sea Level Science, stated that the sea activity in the Caribbean Sea is like a whistle. When one blows into a whistle, the current of air is destabilized and animates the resonant sound wave that is in the hole. One can hear the vibrating sound since the whistle is open.
Also, a sea current in the Caribbean Sea ends is destabilized and causes resonance of an unusual sea wave named a ‘Rossby wave’. Since the Caribbean Sea is somewhat open, there is an interchange with the other water which enables us to ‘hear’ the resonance utilizing gravity estimations.”
Minor alterations in the sea level may cause big rise of the possibility of flood damages and Barranquilla, in Colombia, has been recognized as a city where flood damages will abruptly rise with 20 cm of sea level increase.
Researchers think that the `Rossby whistle’ might likewise affect the whole North Atlantic, as it controls the stream in the Caribbean Current, the antecedent to the Gulf Stream, a significant cog in the sea’s climate motor.
