Abstract: Royal Society International Geophysical Year Expedition c/o The Royal Society Burlington House London W.I HE three years of total atmospheric ozone observations at Halley Bay (75° 31´ S. 26° 37´ W.) do not fit into the world-wide picture of the ozone distribution first measured by Dobson1 from 68° N. to 44° S. Maximum amounts of ozone are not observed until the equivalent of 2-3 months after the seasonal maximum in high northern latitudes and the highest values observed in the southern hemisphere are lower than in the north. Fig. 1 shows that the type of seasonal variation at Halley Bay is also present but much lass definite ten degrees to the north at Argentine Islands ; the seasonal variation of ozone at both stations differs greatly from the variation found at high-latitude northern stations. International Geophysical Year observations of total ozone at Macquarie Island Melbourne and Brisbane show a more 'normal' seasonal variation. . . . .
