Calculational results of the total content of atmospheric ozone at a high—latitude station on Heiss Island (81°N, 58°E) using a Brewer spectrophotometer are analyzed. The ground—based measurements in those latitudes during polar nights of 1989—1994 did not reveal any significant periods of any substantial decrease in the ozone content of the atmosphere. The summer observations of 1992 and 1993 indicate a substantial reduction of ozone compared to the climatic mean values. The maximum decrease of ozone (monthly mean is 16.7%) was observed in August, 1993, and the decrease of the total ozone content during April—September, 1993, was 13.2%.
