ACE Arctic
Validation Campaign
Extended Phase Report
March 9
The ACE science team leaves Eureka. I was sad to see
everybody
go. All the activity at the lab was fun, the foxes not as good company
and the polar bears are distinctly unfriendly.
I am now left alone at
the lab to run the DA8 spectrometer and monitor the U of T
spectrometer. There are still eight staff of the weather station, 15 km
away at the bottom of the mountain.
March 10-13
The sun is getting higher each day. Where are all my
friends?
March 14
I got brave and
decided to investigate the air circulation system in the lab to see if
I could cool off the lab containing the U of T spectrometer. It turns
out to be far more complicated than I first thought; Involving 5
thermostats of 3 different types in 2 different rooms, 3 master
breakers, and 4 different circulation fans. I eventually figured it all
out so I could control the temperature in the “U of T lab”.
Unfortunately the fruits of my efforts were to be mostly wasted...
March 15
Today I first noticed problems with the U of T
spectrometer.
There was almost no useful data from now until March 29.
March 16-19
I
am now running the DA8 and getting used to being here alone. I am also
trying various experiments trying to get the U of T spectrometer
running again and seriously contemplating the merits of just tossing
the thing off the roof. Sorry Annemarie.
March 20
After much back and
forth between Annemarie and me, we decided to take the spectrometer off
the roof and investigate. It takes two people to get the spectrometer
down, so I recruited the help of Paul Loewen, an engineer from the
University of Saskatchewan. We had what were probably the worst
conditions in weeks to work outdoors. The temperature was below -40 C
and the wind was very brisk. The “dome” was sealed remarkably well and
required all the strength of both of us to pry off. When we got the
spectrometer down and taken apart, the shutter was very obviously
broken. Consequently we put the spare (that is old) shutter in, hoping
it would work better. Tests in the lab were positive. We decided that
it was too cold and windy to put the spectrometer back on the roof
March 21
An honest to goodness full day off, ahh…
March 22
Today we put
the spectrometer back on the roof. It was a much more pleasant day for
working outside since the frostbite time was greater than 30 seconds.
Today was too cloudy for DA8 measurements again so I
worked around the
lab and monitored the U of T spectrometer. There have been some
problems with the toilets flushing slowly or having to be plunged in
order to flush. I did my best to solve this, but without much success.
March 23
Ken Kehler, who is a weather station inspector, came
up to
visit the lab today and see if he could calibrate our anemometer. He
discovered that the wind speed measurements were completely
disconnected so he could not get them working in the short time he had.
Today the sewer pipes in the building completely
froze. The showers and
toilets would not drain. There were also intermittent power outages in
the morning.
March 24
The replacement shutter for the U of T spectrometer
seems to
have jammed open. This initiated a desperate scramble to get a new
shutter up to Eureka for the March 28 produce flight.
Two of the
weather station staff came up to the lab to try to unfreeze the sewer
pipes.
I came up to the lab after diner to take some
observations with
the DA8 concurrent with the ozone sonde launch.
March 25
The guys from
the weather station finally got the sewage pipes to drain again after
dismantling most of the sewer system and using up almost all of my
water reserves running hot water through the pipes.
March 26 - 27
Running the DA8 and waiting for the new shutter to
arrive
March 28
The
regular produce flight which was supposed to arrive today was delayed
because the food did not arrive in Resolute on time. This is fairly
common in the arctic where all schedules necessarily have a degree of
flexibility to them. I also took the day off.
March 29
The produce
flight arrived today with the new shutter for the U of T spectrometer.
There was a bit of last minute confusion at the station and I was
initially told there was nothing for me on the plane. A closer
inspection of the food parcels revealed that one of them was the
shutter I had been waiting for.
March 30 – April 4
We are all preparing
for the arrival of the Canadian Rangers sovereignty patrol. There are
twenty people coming from Resolute Bay on snowmobiles. The trip will
take them four days. Eight of them will then continue on to CFS Alert.
April 5
A plane load of media arrived this morning to meet
the rangers.
The Rangers pulled in to Eureka around dinner time. It was quite a show
with twenty loud snowmobiles zooming around. With the rangers, their
support team and the media here there are 50 extra people at the
station. That’s more than they have ever had here in the 50 year
history of the station. I was banished to sleep at the lab while
everybody is here, but I still come down to the station for diner. It
seems like a foreign place. Every nook and cranny of the station is
full of people.
April 6
I gave a tour of the lab to about 15 interested
media people including an on camera interview for a few of them. The
tour went well and I think it will be a good thing to increase
AStrO/PEARL’s profile in the public consciousness.
April 7-8
Things are
wrapping up with the media and I am finally allowed to move back in at
the weather station
April 9-13
Things are back to normal operations
again. Now it is time to start thinking of packing up and shutting down
the lab for the season again. It is getting much brighter these days so
I am getting out hiking and Rose Rock hunting much more.
April 14
In
the last few days the U of T spectrometer shutter is again having
intermittent problems. It seems to be getting stuck open.
I took
observations with the DA8 late into the evening to compare with the
ozonesonde.
April 15
The last day of observations for both the U of T
spectrometer and the DA8
April 16-17
These are the last two full days for me in Eureka. I
am now
packing up the instruments and shutting down the lab for the season
April 18
The scheduled Charter from Resolute was delayed by a
day
April
19
Flight from Eureka to Resolute Bay
April 20
I visited the school in Resolute bay and gave them
an old
scanner from AStrO.
April 21
Flight from Resolute Bay to Ottawa
April 22
Flight from Ottawa
to Toronto.
I arrive home at last. It’s been a good trip
