Where was the hole in the ozone layer discovered?
Antarctic
In the scientific journal Nature on May 16, 1985, three scientists from the British Antarctic Survey announce their detection of abnormally low levels of ozone over the South Pole.
Who discovered the hole in the ozone layer?
Jonathan Shanklin
In 1985 Jonathan Shanklin was a junior researcher at BAS when he discovered a hole in the invisible shield that protects us from solar radiation. We catch up with him to learn about his work and how it has made a difference. It’s 36 years since scientists first discovered the hole in the ozone layer.
How was ozone layer discovered?
The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. Dobson, who developed a simple spectrophotometer (the Dobsonmeter) that could be used to measure stratospheric ozone from the ground.
Is there a hole in the ozone layer above Australia?
Scientists say the hole in the Earth’s protective ozone layer over the Southern Hemisphere is larger than usual this year and already surpasses the size of Antarctica.
When was the first ozone hole discovered Mcq?
Explanation: The ozone hole was discovered in the year 1984 by Jonathan Franklin, Joseph Farman and Brian Gardiner. Explanation: The phenomenon of the ozone hole occurred in the Antarctic region primarily due to catalytic breakdown of ozone molecules by halogenated compounds.
When was the ozone hole discovered?
1985
Researchers at the British Antarctic Survey discovered the ozone hole in 1985, and NASA’s satellite estimates of total column ozone from the Total Ozone Mapping Spectrometer confirmed the 1985 event, revealing the ozone hole’s continental scale.
Why is the hole in the ozone layer above Australia?
As sun-loving Australians, we’re all too familiar with the damage UV can cause. During the 1980s, scientists discovered that key ODSs known as chlorofluorocarbons (CFCs) caused significant damage to the ozone layer. This resulted in the so-called ‘hole in the ozone layer’.
What created the ozone hole?
The ozone hole has developed because people have polluted the atmosphere with chemicals containing chlorine and bromine. The primary chemicals involved are chlorofluorocarbons (CFCs for short), halons, and carbon tetrachloride.
What is the ozone hole?
The ozone hole is not technically a “hole” where no ozone is present, but is actually a region of exceptionally depleted ozone in the stratosphere over the Antarctic that happens at the beginning of Southern Hemisphere spring (August–October).
How is the hole in the ozone layer?
The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS).
How was the ozone layer formed?
Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons. This reaction can occur both near the ground and high in the atmosphere.
