And it is this last observation that is finally here for the Antarctic ozone hole in particular, the new study asserts. In the research, the researchers used satellite and balloon data to examine the seasonal Antarctic ozone hole for a 15-year period between 2000 and 2015. October of 2015 actually showed a quite large ozone hole over the ice continent. October, the peak month for Antarctic ozone depletion, is another matter. But it wasn’t until the sudden discovery of a vast seasonal ozone “hole” over Antarctica in 1985 that the world was shocked into action.
