OZONE
Continued from Page 1
Despite the name, the "ozone
hole" is simply a lessening of
0/0110 molecules above the Art:
tic and Antarctic .liter those re
gions’ seasons of extended
darkness end Within three to
four weeks, tin; o/.one level re
turns to normal.
Rasmussen saltl that in the
late 1 l)?()'s the phenomenon
was discovered over the Ant
arctic:. For the next six to seven
years, the phenomenon was
tailed the "ozone minimum '
But with the perpetual need lor
research funds the ‘‘o/.one
minimum" became the "ozone
hole
By making the phenomenon
sound more threatening, scien
tists got more funds to sltidv It.
Rasmussen said.
Later, NASA said a high alti
tude flight had found the de
struction of the o/.one layer Was
occurring three titties taster
than previously thought
That conclusion was based
on one flight that had been
done out of J-i, said Brian Dun
bar, a NASA spokesman 1 he
flight they had mentioned,
Dunbar said, happened to be
the one that measured the high
est level of ozone depletion
In fact, NASA will not re
lease the findings of the other
Tl flights until after March
