In the study hence published on Monday in the Proceedings of the National Academy of Sciences journal, scientists described the area as "truly pristine."

As the climate changes rapidly because of human activity, scientists and researchers have always struggled to find a corner of the Earth unaffected by people.

But researchers from Colorado State University have now identified an atmospheric region which remains unchanged by human activity. They say it is the world's cleanest air, free from particles caused by human activity, located over the Southern Ocean, which surrounds Antarctica.

This result was based on a first-of-its-kind study of the bioaerosol composition of the Southern Ocean.

Researchers found that the boundary layer air, which feeds the lower clouds over the Southern Ocean, was free from aerosol particles produced by human activity -- including burning fossil fuels and wastewater disposal -- or transported from other countries around the world.

Research scientist and co-author of the study Thomas Hill explained that "the aerosols controlling the properties of SO (Southern Ocean) clouds are strongly linked to ocean biological processes, and that Antarctica appears to be isolated from southward dispersal of microorganisms and nutrient deposition from southern continents," he said in a statement.

"Overall, it suggests that the SO is one of very few places on Earth that has been minimally affected by anthropogenic activities," he added.

Scientists sampled the air in the marine boundary level, and then examined the composition of airborne microbes. And found that the microbes' origins were from the ocean.

They also concluded that aerosols from distant land masses and human activities, such as pollution or soil emissions caused by land use change, were not travelling south and into the air.

Scientists say that the results show a stark difference to all other studies from oceans both in the northern hemisphere and subtropics, which found that most microbes came from upwind continents.
