However, Professor Sonia Kreidenweis and her team suspected that the air above the Southern Ocean was least affected by humans and dust from the continents of the world.
The researchers found that the boundary layer of air, which feeds the lower clouds above the Southern Ocean, is free of aerosol particles produced by human activity. – including burning fossil fuels, growing certain crops, producing fertilizer, and disposal of wastewater – or transported from other countries around the world.
The researchers decided to study what is in the air, and where it came from, using bacteria in the air as a diagnostic tool to deduce the properties of the lower atmosphere.
Research scientist and research co-author Thomas Hill explains that “the aerosols that control the properties of SO (Southern Ocean) clouds are strongly linked to ocean biological processes, and Antarctica appears to be isolated from the spread of microorganisms to the south and the deposition of nutrients from the southern continent,” he said in a statement.
“Overall, this shows that SO is one of the few places on Earth that has been slightly affected by anthropogenic activities,” he added.
The scientists tasted air at sea level – part of the atmosphere that has direct contact with the sea – while boarding a research ship traveling south to the Antarctic ice bank from Tasmania, Australia. The scientists then examined the composition of microbes in the air, which were found in the atmosphere and were often scattered thousands of kilometers by wind.
Using DNA sequencing, source tracking, and wind back trajectory scientist and first author Jun Uetake found that the origin of microbes came from the sea.
From the composition of microbial bacteria, the researchers concluded that aerosols from distant soil masses and human activities, such as pollution or soil emissions caused by land use changes, do not move south and into the air.
Scientists say that the results show a marked difference with all other research from the oceans in both the northern and subtropical hemisphere, which found that most microbes originated in the windward continent.
Air pollution has become a global public health crisis, and kills seven million people each year, according to the World Health Organization (WHO).
More than 80% of people living in urban areas who monitor air pollution are exposed to air quality levels that exceed WHO guidelines, the health organization said, and low and middle income countries suffer the highest exposure.
China Vows to Retaliate Immediately after Trump Signs Hong Kong Sanctions Bill
China on Wednesday sharply criticized President Trump’s moves to strip Hong Kong of its preferential buying and selling status with the United States and crystal clear the way for new sanctions on officers and firms there, vowing to retaliate with punitive measures of its own.

“It is gross interference in Hong Kong affairs and China’s interior affairs,” the ministry claimed.
The effect of the new powers thorough in the American regulation and Mr. Trump’s executive buy continue to be to be witnessed. Congress has authorized comparable measures prior to, only to have the administration hold off imposing them as it weighed other international policy concerns, including Mr. Trump’s signature trade deal with China.
With relations deteriorating poorly and the pandemic’s toll mounting in the United States, the administration has acted much more aggressively in recent weeks.
When the United States imposed sanctions on 4 Chinese officials about China’s crackdown on Uighurs and other Muslims in the considerably western area of Xinjiang, Beijing reciprocated by announcing journey bans and sanctions on outstanding Republican users of Congress.
Lau Siu-kai, a senior adviser to the Chinese authorities on Hong Kong coverage, claimed the American steps would have constrained impact on Hong Kong and would, contrary to the intent of the United States, travel the territory closer to mainland China.
“The overall damage to Hong Kong and to China is fairly negligible and can be absorbed,” mentioned Mr. Lau, a former senior Hong Kong govt formal who is now with the Chinese Association of Hong Kong and Macau Studies.
He explained Hong Kong was getting to be “increasingly detached from the United States and the West, and significantly attached to China and Asia.”
Other individuals reported the American steps could have additional important effects by hurting the city’s status for openness and rule of law. That could have an impact on providers as very well as academia.
“The only way we can regain the regard and favorable ailments that we are entitled to is if Beijing fulfills its primary promise to the entire world and Hong Kong folks, which is the legitimate implementation of ‘one state, two systems’ and our substantial degree of autonomy,” said James To, a pro-democracy Hong Kong lawmaker.
