A study of the Caribbean Sea by University of Liverpool ocean scientists has revealed that, in the midst of all the noise of the ocean, this region behaves like a whistle, which blows so loudly that it can be 'heard' from space in the form of oscillations of the Earth's gravity field.
The Caribbean Sea is a part of the Atlantic Ocean, southeast of the Gulf of Mexico. It is a bounded by South America, Central America and the Caribbean islands, and covers an area of approximately 2,754,000 km2 (1,063,000 square miles).

Researchers analysed the sea levels and pressure readings taken from the bottom of the Sea using four different models of ocean activity in the Sea over the period 1958 up to 2013 as well as using information from tide gauges and satellite measurements of gravity.
They noticed a phenomenon which they have called a 'Rossby Whistle' which happens when a Rossby wave -- a large wave which propagates slowly to the west in the ocean -- interacts with the seafloor.
