The deepest point on Earth hides many secrets

This oceanic space is different from its surroundings, and is also known as a space burial place. Until recently, scientists have not had a clear view of life in these mysterious waters, which occupy 10 percent of the earth's surface.

The South Pacific vortex, for this reason, is always considered a desert for marine biology.

Despite its isolation, life survives there, and the causes of ecosystem shortages are numerous and include distance from earth's nutrients, the way water circulates the vortex center from the rest of the ocean, as well as high UV levels.

Exploring this ocean desert is a very challenging effort, such as because of the distance and size of space that covers 37 million square miles [37 million sq km]. Despite these challenges, scientists have recently been able to look into the water system there.

The crew, led by researchers from the Max Planck Institute for Marine Microbiology in Bremen, Germany, set out on a six - week expedition stretching from Chile to New Zealand. Thanks to the efforts of researchers at the Institute, microbiological data gathered from a depth of five miles [5 km].

The findings have confirmed that the number of microorganisms on the South Pacific surface is three times lower than the number of cells in the Atlantic vortex.

It's probably the smallest amount of living cells ever measured in the ocean,” says Bernhard Fuchs, a microbiologist and ecologist whose team tests collected samples. Fuchs team confirmed that the search will continue.
