Significant Ozone Hole Remains Over Antarctica

NOAA - Washington, DC, USA. (November 17 2009).

The Antarctic ozone hole, which fluctuates throughout the late winter and spring in the southern hemisphere, reached its 2009 peak circumference in late September, according to measurements by NOAA researchers... Measured in Dobson Units (DU) that indicate the amount of ozone in a vertical column of air, the 2009 low level – 98 DU – is the seventh smallest since 1986. The record low of 89 DU was recorded on Oct. 6, 1993....

Ozone Hole Reduces Atmospheric Carbon Dioxide Uptake In Southern Ocean

ScienceDaily (June 24, 2009).

Does ozone have an impact on the ocean's role as a "carbon sink"? Yes, according to researchers from three laboratories attached to INSU-CNRS, UPMC, CEA, IRD, MNHN and UVSQ. Using original simulations, they have demonstrated that the hole in the ozone layer reduces atmospheric carbon uptake in the Southern Ocean and contributes to the increase in ocean acidity...
