The puffs of ice crystals that appear where ice and sea meet may not be responsible for the depletion of ozone near the poles as been previously thought. Thus, the seasonal dip in ozone near the poles cannot solely blame these popcorn-sized puffs of ice crystals.
The ice crystals have long been thought the source of the bromine oxide that triggers the deposition of the mercury from the atmosphere and the depletion of ozone near the poles. But new findings are defying this. The findings suggest that the ice blooms do not affect the polar atmosphere as expected’ You wil find more on it in the New Scientist magazine.
