Ozone observatory "mothballed"
until further notice
Ellesmere Island lab
could be reopened in two years if Environment Canada finds enough money

A lab that measures the
ever-decreasing ozone levels in the Arctic has been closed indefinitely because
of funding cuts at Environment Canada.
The Arctic Stratospheric
Ozone Observatory, located about 15 kilometres from the Eureka weather station
on Ellesmere Island, opened in 1993 and has been continually collecting data
on the substance that protects us from the suns ultraviolet rays. Scientists
from Canada, Japan and the United States had used the facility, which closed
last month.
Angus Fergusson, Senior
Meteorologist Stratospheric Ozone and UV Issue Manager with Environment Canada,
said the lab is being "mothballed" for two years. All scientific instruments
have been removed, but the building will be kept warm so that it can be used
again if more funding is found. An employee from the Eureka weather office will
be looking after the building, he said.
"Weve been running
the station since about 1992 and in the last number of years it was running
with a budget of about $500,000," Fergusson explained. "If things
deteriorate up there and we get some more money to do some research then well
be able to move back in and open the lab again."
It costs the government
about $200,000 to maintain the building and another $300,000 to fly in Canadian
scientists and their equipment each year.
He said, in 1995, Environment
Canadas budget was cut over a number of years and the agency is trying
to work within the budget it has been left with.
"It comes down to
a fact that we have to set our priorities, what we want to do and some things
have to go and some things stay," he said, but hope is not lost for the
ozone lab.
"Were still
concerned over the fact of ozone depletion in the Arctic and for the last two
winters its been very warm in the Arctic stratosphere so we havent
seen much ozone depletion," Fergusson said. "But in the winter of
2000, it was very cold and there was quite a bit of ozone depletion monitored
up there." The lab is being maintained in case more research needs to be
done and the money becomes available to fund that research.
Kimberly Strong, an atmospheric
scientist at the University of Toronto, said the closure is bad news, especially
since long-term monitoring of ozone depletion is sorely needed.
"If the federal government
is really going to close it down, myself and a number of colleagues are trying
to put together a group of university and government scientists to somehow try
and save it to raise money from a number of different programs,"
she said. "Thats in the very early stages and were kind of
gathering support at the moment and well see where that goes."
There is another station
in Norway that measures ozone levels, she said, but its not enough.
"Its about long-term
monitoring. Its something the federal government should be doing, budget
pressures notwithstanding," she said. "Its difficult for university
people to do because grad students and post-doctoral researchers are here for
short periods. To get that kind of long-term continuity you need those government
scientists who are doing measurements for long periods and become very familiar
with their equipment."
Fergusson said although
Environment Canada has said the lab will be maintained for two years, the feeling
is that the station will remain "mothballed" until more funding is
found. If a consortium of universities and scientists can come up with extra
dollars, its a good thing.
"We hope to save it
in the long term," Strong said. "But people need to be aware of the
fact that it has been closed. At the present time there are no plans to reopen
it."
