Getting out of your front door every morning and swallowing two lungs of fresh morning air is as good as it can get - Especially during the pandemic.
"These results provide observational support for the suggestion that this region of the Southern Ocean represents one of very few marine boundary layer regions across the globe that is unlikely to have changed due to anthropogenic activities", the researchers wrote.
The researchers found that the air of the boundary layer, which feeds the lower clouds over the Antarctic Ocean, was free of aerosol particles produced by human activity- including the combustion of fossil fuels, the planting of certain crops, the production of fertilizers and the disposal of waste water - or transport from other countries of the world. Thanks to some quirks of global climate and weather patterns, the clouds over the Southern Ocean are pristine. You may find our garbage from the remote regions of the ocean, our plastics washed up on secluded beaches where humans do not even reside, and our compounds in the clouds are hovering high. I mean, unless you're heading far, far south.
The research team, however, strongly suspected that the air over the Southern Ocean would be protected from human activity and pollution. It is about as clear as it can get, and it still exists here on Earth.
Scientists have taken samples from the atmosphere near and above the sea surface. They studied the composition of microbes found in the air, which may offer a clue to where the air has been. They discovered that the microbes likely originated in the ocean. Unsurprisingly, the place is far away from all human inhabitation.
Research scientist Thomas Hill, the coauthor of the study, said, "We were able to use the bacteria in the air over the Southern Ocean as a diagnostic tool to infer key properties of the lower atmosphere." .
It is fantastic to hear about an aspect of Earth's natural methods that humans haven't managed to destroy over the centuries.
Scientists then examined the composition of airborne microbes, which are found in the atmosphere and often dispersed thousands of kilometers by the wind.Using DNA sequencing, source tracking and wind back trajectories scientist and first author Jun Uetake found that the microbes' origins were from the ocean. You have to wonder how long it will be before someone decides to bottle that air and sell it at Walmart checkouts for 99 cents.
