'Extreme contrast found <strong>in</strong> ozone losses at Poles'<br />
Press Trust of India<br />
Chicago, December 26, 2006<br />
A new study shows just how dramatic the ozone loss <strong>in</strong> the Antarctic has been over the<br />
past 20 years, compared to the same phenomenon <strong>in</strong> the Arctic.<br />
The study found "massive" and "widespread" localised ozone depletion <strong>in</strong> the heart of<br />
Antartica's ozone hole region, beg<strong>in</strong>n<strong>in</strong>g <strong>in</strong> the late 1970s, but becom<strong>in</strong>g more<br />
pronounced <strong>in</strong> the 1980s and 90s.<br />
The US government scientists who conducted the study said on Monday that there was<br />
an almost complete absence of ozone <strong>in</strong> certa<strong>in</strong> atmospheric air samples taken after<br />
1980, compared to earlier decades.<br />
In contrast, the ozone losses <strong>in</strong> the Arctic were sporadic, and even the greatest losses<br />
did not beg<strong>in</strong> to approach the regular losses <strong>in</strong> the northern hemisphere, the researchers<br />
said.<br />
"Typically the Arctic loss is dramatically less than the Antarctic loss," said Robert<br />
Portmann, an atmospheric scientist with the National Oceanic and Atmospheric<br />
Adm<strong>in</strong>istration <strong>in</strong> Boulder, Colorado.<br />
Scientists have been track<strong>in</strong>g the expand<strong>in</strong>g ozone hole over Antarctica for some 20<br />
years now.<br />
In October, NASA scientists reported that this year's hole is the biggest ever, stretch<strong>in</strong>g<br />
over nearly 11 million square miles.<br />
In Antarctica, local ozone depletion at some altitudes frequently exceeded 90 per cent,<br />
and often reached up to 99 per cent dur<strong>in</strong>g the Antarctic w<strong>in</strong>ter <strong>in</strong> the period after 1980<br />
compared to earlier decades, the researchers said.<br />
In the Arctic, the losses occasionally peaked at 70 per cent, and some losses of 50 per<br />
cent were seen <strong>in</strong> the mid 1990s, when temperatures were particularly low, but the scale<br />
and scope of the problem was much less than what was seen <strong>in</strong> the Northern<br />
Hemisphere.<br />
