British Antarctic Survey Ozone Bulletin No 14 Issued from Faraday station, Antarctica, 1995 December 3. Due to limited data resources available at the station this bulletin is less detailed than those issued from the UK. Total ozone values at the British Antarctic Survey Faraday station (65 deg S, 64 deg W, off the coast of the Antarctic Peninsula) have continued to oscillate as the station passes under the edges of the ozone hole. Present values are considerably less than the long term mean for the station, which is around 370 DU for early December.

This is the second lowest November monthly mean at Faraday, the lowest being 231 DU in 1993. The minimum value reached during the month (152 DU) is also the second lowest on record, with the minimum being 139 DU also in 1993. Total ozone values at the British Antarctic Survey Halley station (76 deg S, 26 deg W, on the Brunt Ice Shelf) held steady through mid November at around 160 DU, but rose to around 210 DU towards the end of the month. Present values are considerably below the long term mean for the station, which is around 380 DU in late November.

This is the second lowest November monthly mean at Halley, the lowest being 170 DU in 1993. The minimum value reached during the month (142 DU) is also the second lowest on record, with the minimum being 125 DU also in 1993. Regards, Jon Shanklin
