The week ending November 25, 1994 in McMurdo
This week has gone by REALLY fast, and it feels like a good and full
week! I started working the evening shift, meaning I don't have to go
to work until 5pm. I have been getting up at 9am and doing all kinds of
fun things!
Monday I went in to the bio lab here in the morning and used one of
the computers. There is a neat library in there that has a GREAT view,
and there are some computers there anyone can use. I have since found
that the room is usually quite crowded with scientists using the machines.
When I was there, though, it was a quiet Monday morning.
After lunch I went into the Greenhouse which is always nice. It is WARM
in there, and humid and it is nice to be among PLANTS! They have installed
some plastic curtains (like you find in the frozen section at grocery
stores) and so one of the rooms is cooler than the other. The lettuce
room is about 70F and the tomato/herb room is about 80F. All over there
are humidifiers and fans and BRIGHT LIGHTS. I measure pH, then adjust
it for what the system likes. For example, lettuce kind of likes things
acidic, while tomatoes don't. We have 5 systems in all, and I have to
check all of them. The other thing I check is conductivity. That has something
to do with the nutrients. These plants all grow by sucking up nutrients
from water (here is no soil). I still have to learn what the nutrients
are, but there is an "A" nutrient and a "B" one. We measure the conductivity,
look on a chart, and then figure out how much nutrient to add. (We always
add equal amounts of A and B). I also measure the temperature, humidity,
and check the systems to see if they need water. If anything needs harvesting
I do that too.
Monday I added water to all the systems and found out that the pH meter
is broken and I couldn't get the conductivity meter to work. I then filled
all the humidifiers, and in the process I blew a fuse, so had to call
someone to come in and help me figure out how to make it right again.
It wasn't a very productive time, but it was great being in there. Right
now we have a lot of different kinds of lettuce growing, some cucumbers,
sweet peppers, tomatoes, and a few herbs (basil, chives, thyme, cilantro).
Sometimes I pick lettuce and take it to the galley, but that usually takes
a while, so I didn't do it this time.
Tuesday was a bit breezy, but I decided to climb Ob Hill to get some
exercise. I had been skiing on Sunday and my muscles were SORE! It was
great to get out and stretch my legs. I bundled up really good and the
wind didn't bother me.
After lunch my friend who is the cook at Scott Base came over for a
cup of tea and we caught up on all his escapades. He is a typical Kiwi
- full of vim and vinegar and ALWAYS up to something. He told me that
he had gone out to Cape Evans (15 miles away) and got another guy to walk
back with him. They took a sled with survival gear and used skis in the
spirit of Cmdr. Scott in days of old. He said it was something to haul
the sled....rough ice and skis not wanting to grip the ice, sounded like
an ADVENTURE.
From there I went into the MARS shack and learned how to send marsgrams.
I have been volunteering as a typist now for the past two years and I
have wanted to be the operator that SENDS the grams since 1992. I have
spent a LOT of time up there learning, but never been able to DO it. This
time they let me do it as they watched. I had a good time, but the radio
waves weren't very cooperative.
After that I ran into some scientists I had met last year. They are
studying giant foraminifera, some kind of single-celled animal. It is
so large that you can see it unaided by a microscope. I heard about them
all last year but had never seen one. I went over to the lab to look and
by golly, if they aren't something. They actually secrete some kind of
slime or spit and incorporate sand, silt or shells to make a protective
case. I didn't really see the "animal", but got a gander at the "shell".
There are many different kinds of forams, and each kind uses it's own
signature material for its case. Some like silt, some like granite grains,
etc. One of the scientists was sorting through the guck they had scraped
up from the floor of the ocean and was picking these things out and sorting
them into piles. I got to look through the microscope and there were some
other neat things to see too. I saw a tiny worm, a little shrimp, a minute
starfish and some other neat translucent things.
Work has been going really well, there are a lot of people out in the
field camps to talk to and my time at the radios just flies by!
