             abstract = "During the Springs of 2003, a field campaign was organized to 
                         measure the vertical distribution of ozone at the Brazilian 
                         Antarctic Station, on King George Island (62.1 S; 58.4 W). The 
                         Electrochemical Concentration Cell, ECC sonde technique was used, 
                         launched on balloons. 20 successful ozone soundings were obtained 
                         during september and october. Several of these soundings showed 
                         severe depletion of stratospheric ozone, mostly in the lower 
                         stratosphere, which reached a maximum on october 06. During this 
                         period the total column ozone and the UV-B radiation were also 
                         measured daily with a Brewer spectrophotometer. The UV-B radiation 
                         reached an index of 9.9, the largest ever recorded at this 
                         location and the total ozone content varied considerably: between 
                         121 Dobson Units (DU) on October 06 and 391.6 DU for november 
                         03.",
