STILL A BIG OZONE HOLE OVER SOUTH POLE
The Antarctic ozone hole, which yawns wide every Southern Hemisphere spring, reached its annual peak on September 12, stretching 26.03 million square kilometres (10.05 million square miles), the ninth largest on record. Above the South Pole, the ozone hole reached its deepest point of the season on October 9 when total ozone readings dropped to 102 Dobson units, tied for the 10th lowest in the 26-year record, reports ScienceDaily.
