19 October, 1995
Thursday, October 19, 1999 We are at 64.19 south latitude and west
longitude in the Gerlache Strait. We woke to snow on the deck this morning
and it had started last evening when the temperature dropped to about
-4.000 degrees centigrade. It got cold last night while working on deck
and I was grateful to have completed that job of pumping water and
retrieving some buoys that had been drifting all day by 1930 hours or so.
It snowed about 6 inches and it was dry, not the wet Puget Sound snow we
are so used to.
Today is a kind of lazy day, however work is being done. We were to drop
over the depth sampling devices that have been designed for this trip and
we were to drop them over board to depths of surface, (now that is a good
one George, how deep is the surface?) 1,2,3,5,7,10, and 12.5 meters. They
float all day in the straits and then we pick them up in the evening and
the samples carried in the boxes at these pre-determined depths are then
studied at night to look for effects of ultraviolet light that may have
occurred during the day. We were to do that today, but the overcast sky
and the snow changed that. By 1000 hours this morning, it was clear, sunny
and -2.000 degrees centigrade, suntanning and shirtsleeves weather. We can
walk on deck in shirt sleeves and no fleece. Well, you can walk all
around and then jump up and down, but if you stay out too long, it gets
cooollldddd!!!!!!real fast - but the water is flat, there is no wind and if
we were in the tropics.
We finish up our second 24 hour sampling the next day and it went much
smoother with everyone getting breaks, not like before. Also during our
first 24 hour sampling, it was a 24 hour blizzard and this time the sun was
out and the weather was pretty nice. It is amazing how your attitude can
be affected by the weather. How much do we know about the
weather?????There may be some questions that need asking here and then some
answers; For Instance; Why does the barometer go down and why does that
indicate bad weather?, Why does it go up and what about good weather
causes that?, Now why when is very bad weather here in Antarctica does the
barometer appear to be up and when it is nice like now, the barometer reads
962.5 millibars (the lowest I have seen here yet). For some of you it
would be good to convert the millibars to inches of mercury because your
home barometers read that way, but if you listen to the NOAA weather
forecast on whatever megahertz it is at, way down to the left on your FM
channel receiver, they give the barometer readings in millibars.
Anyway, it is beautiful. This could inspire some creative thinking. The
wind comes up here so fast that it is surprising to find yourself in
weather like this and then look at the horizon and se the dark bearing down
on you and all of a sudden the wind is blowing 40-50 MPH.
I was on the bridge of the Polar Duke this morning and we were looking out
on the flat surface of the straits and saw Minke whales, leopard seals (big
mouths and sharp teeth) and penguins swim by. I looked out at the shore
and the captain asked me how far I thought we were from shore. So I took
the George Palo experience at sea logic and combined that with my "I am a
scientist and educator attitude", and said we were about 400 meters or a
quarter of a mile from shore. Take me about 90 seconds to run it. He
immediately began chuckling as did the 1st officer which led me to believe
that they couldn't believe how accurate I was. (Now you have to remember
that I am the type of guy that when he is at the top of a pass and my
altimeter watch doesn't read what the sign say, I think that the sign is
wrong.) The captain stepped over to the radar, turned up the gain, changed
the scale and dialed in the distance .Must have been a broken radar ..it
said were 8000 meters from shore or a roughly, a little over four miles
away. The clarity of the air and the size of the objects makes everything
look closer. I have gone out twice since then to see if it still looks 400
meters away and I will tell that each time it does. There is an area of
glaciers that I thought then would be a short walk from the ship and the
radar said 6.2 miles away, that is nautical miles by the way so divide by
1.2 for regular miles. The air is clear, but think how big everything must
be to appear so close. The people on the ship call it invisible air.
The areas' waters are floating with pieces of ice and icebergs and it is
fun to move through them and see what is on them. The colors are
absolutely beautiful because the aqua blue green is absolutely transparent
looking.. The water is very clear and you can sometimes see to 100 feet
which is good for polar seas. You have to go to the tropics to see this
elsewhere. The icebergs take on visions that become sculptures in your
mind, becoming the object that you want it to be. I often conjure up
visions of places where characters of fairy tales belong or are sneaking
around on the ice watching us invade their private secret water and land.
It is rally cool (no pun intended) to let your mind and imagination run
wild ( I have often been accused of living my life like that) but anyway it
is stellar man, to look out on the water and see houses, castles, ships and
animals all floating around the Gerlache Strait with us enjoying the
Antarctic.
So what kind of ship is the Polar Duke anyway? It is a ship built in
Bergen, Norway (ask Paul Wise to pronounce that for you) in 1982. It is
registered in Newfoundland, St. Johns to be exact. It is 66.8 meters long
and 13 meters wide. It has a controllable pitch or variable pitch
propeller on it. That is an interesting fact because the engines always
run at 600 RPM whether you are idling or running full out. The pitch of
the prop blades is what is changed to determine whether you are stopped,
going forward, or in reverse. The main power plants are 2 MAK 453, 4500
horsepower each. It also has bow and stern side thrusters of 500
horsepower each. It has a crew of 14 to maintain and drive the ship and
all but three are Norwegian. The other three are Chilean. So sometimes
when I am in the galley area during meals, there is a Norwegian
conversation on my left and a Chilean conversation on my right, and I might
be talking to myself. As you can see , there are three conversations going
on that I don't understand. There are nice accommodations on the ship with
the rooms being two person rooms. We dropped a lot of people off at Palmer
Station so each of us, as I have said before, has our own room. It is good
to have some privacy on a thirty-day cruise. We are lucky. Having your
own room doesn't often happen. You have to realize that we are on day ten
of a thirty day cruise and have twenty days left before we even turn back
to Palmer Station to pick people up. Sometimes the ship gets small. The
crows nest 60 feet off the ground above the bridge has become my private
space and time. You climb up this little tunnel like enclosed ladder that
you enter from the bridge. You can shut the door to the crows nest and I
put on the headphones and WOW, I'm free. Right now down in the lab area,
someone's put on the CD player Smashing Tomatoes meets the Flaming
Icebergs and the music is blowing my brains out down there where people are
processing samples.
We will have a couple of hard days coming up here soon and I'm sure the
dropping barometer is preparing us for something. I am going to be working
on ozone data soon. We need to take data from historical records off of a
CD I brought and try to transfer them to the program Exc3ell and then graph
the data. We hope to graph the data and see results that will allow us the
possibility of predicting ozone hole data and location based on historical
record. So far, it does not seem to work as the hole has a mind of its
own. I am going to close for now. Enough rambling for this time It is of
the most importance that I get the message across to you that in my
estimation, we continue to work in the Antarctic doing research. It is so
applicable to all of our lives. For those of you that say How? Or Why?; I
will try to work out an answer for you and email it later. So until later.
Peace.
George Palo
