Adelie Penguins at sea ice off at Antarctic Peninsula

“It shows a deep connection between ecosystem and atmospheric processes,” as Matthew Boyer at the University of Helsinki in Finland.
The link will come until the way Ammonia affects the number of particles in the air. To form a cloud, water vapor should be able to abilitate around a sized fragment of certain species. But those who are hard to come to the cold of Antarctica, clean air.
Without much dust, vegetation or air pollution around, most of the particles available for a well-be cloud are clusters of sulphuric acid molecules generated as a result of natural emissions from phytoplankton in waters around the continent. The high concentration of ammonia is already known to facilitate the formation of these clusters one thousand fold. But where did Ammonia come from Antarctica? Penguin drops should be a rich source.
To check it, Boyer and his companions measure ammonia concentrations, sulfuric acid and larger air particles a few miles of a 60,000 loud colony in adélie penguins (Pygoscelis Adeliae) On the Antarctic Peninsula. “They will smell,” said Boyer. “They are dirty birds.”
If the air blows from the colony’s direction, they find the concentrations of ammonia above the level of the level found in the air to. This ammonia increase also increases the formation of particles in sulfuric acid enough for water to erase the clouds around them, and maybe to form clouds. This effect continues for many weeks after penguins have moved from the colony.
Many clouds, especially in the ocean, have an effect on the healing by reflecting the day away from the ground surface. Boyer also says it also means a reduction in the Penguin population – for example, because of The loss of sea ice driven by climate change – There is an impact of heating across Antarctica by reducing cloud cover. However, measurements made at current work are not sufficient to estimate the impact size.
Other research suggests that it may be important. For example, Jeffrey Pierce In Colorado State University and his colleagues found Ammonia from the excretions of the Arctic puffin the same Extended cloud cover cover. They estimate this resulting in a cool effect to be canceled as many as a third of the winding due to the carbon dioxide of the air throughout the region. “I’m sure it makes some effect,” Pierce said.
