'Ready, Matt? I'll call out this set of data for you - Inorganics for
Sample 222 are Chloride 26.40, nitrite 30.02, bromide 9.3, nitrate 26.05,
and sulfate 15.06. The organics' (compounds containing carbon) sample
values are formates 465, and acetate 566.' And so goes on the data
collection from the two hundred and twenty-second sample taken and run on
the Ionic Chromatograph (IC). This was the 2nd time I spent a day with the
IC. However, I got to run many of the samples today. I was a
'button-pushin' cowgirl' fer sure. In an IC there is a syringe that intakes
test samples and in between each run, it must be cleaned with
super-filtered water (set up and push 2 buttons, then do it again). After
cleaning, the next sample is put into place and readied for start (set up
and push another 2 buttons). In the meantime, the current run finishes and
the data must be read. Sometimes the charts are difficult for the computer
to read correctly and so they must be checked each time for any errors and
adjustments made. It is an interesting process that requires concentration
so that the right step is done at the right time. And I loved it. A 'data-
hungry' Dr. Jack Dibb kept Matt Arsenault, his graduate research assistant,
and I on our toes to push the samples through just as fast as the system
would allow. And no wonder he was eager for the next set because the data
were quite variable for reasons not yet known, It was a most interesting
day. Tomorrow I will learn how to do a clean collection of snow.
The weather was much like yesterday with blue skies and (relatively) mild
temperatures and wind. I've gotten so acclimatized that the main reason I
wore my coat between buildings was to carry both my slide film camera and
my digital camera. Hat and gloves were not necessary for the minute I would
be outside. Sunglasses are always required. The UV light is so strong here
(the Arctic has its ozone hole, too) that permanent eye damage can result
if the eyes aren't always protected.
Warm regards,
Besse Dawson
