Research: Day Three This day could end up being a day from another chapter
in the story about a teacher that went on a research trip
to Antarctica.
It has snowed all day. Not just snowed but a blizzard - the wind has been
blowing 30-35mph all afternoon and the snow has been piling up on the deck
at the rate of 1-2 inches per hour and it is cold. 0.0 degrees centigrade -
just at freezing but do not forget to add in the wind chill factor. At one
time today, the thermometer read -0.0 degrees. I tried for a long time to
figure that out...the humidity is 99.6% and the barometer is dropping 1-2
millibars per hour. It was at 1002 this morning and it is now 2123hrs and
it is at 982.6 millibars. Oh my gosh, its gone up .4 millibars.
It is still blowing out and the snow is still coming down and with the
barometer at this level the captain says we might have good weather
tomorrow. The problem with that statement and I'm still trying to figure
that out is that he might be right. The weather fronts move so fast through
this area, that by the time the barometer has recorded the pressure, the
new front is on its way or in
the process of arriving.
We get our shipboard weather forecast from the University of
Wisconsin...they provide all the Antarctic weather through their internet
server - yesterdays forecast after an explanation of the highs and lows and
all the etc. etc., was for the Polar Duke: "the weather for today will be
perpetually crappy, but tomorrow it will be better as it will be partly
crappy." I know which part we had today.
We are on a 24 hour sampling project today so all of us will be up al day
and night sampling every 2 hours beginning at 0600hrs and ending tomorrow
at 0600hrs. You can learn to work on 15 minutes of nap at the end of the
sampling period. So today my day was like this: I got up at 0415 to have
some coffee and private time to myself since there would not be any for 24
hours. This is not a big ship at 215 feet and sometimes it seems to shrink
in a matter of minutes.
Our first sampling was at 0600hrs and I'm outside because it is the only
way to break up the monotony of running filtration pumps for two hours.
Rigging the underwater pump, uncoiling the hose, setting it in the crane,
filling the jugs with -0.6 degree centigrade water and then bringing the
pump back aboard, coiling it because outside it would become brittle and
freeze (so it is stored inside a big chest) and carrying 50 liter jugs of
cold southern ocean water is just the beginning. Remember I do this every
two hours in the blizzard snow just to break up my day. Breakfast isn't
until 0730hrs. I then after changing out of foul-weather gear, now watch
small pneumatic pumps pump sea water through .200 and .800 micron filers as
we are trying to filter the bacteria out of the sea water for
identification and DNA counts later. The filtration takes about 1hour 45
minutes. So you can figure up the time scale and how much extra free time
we have left. I will try to explain the entire research project to
you soon. At breakfast time, I skip it and go to my cabin for a 10-minute
nap and get up and start all over again. All day long for two hours, the
same thing.
By this afternoon, it is really snowing and the CTD measuring device needs
to be tested (temperature, depth and conductivity) It is lowered into the
water for calibration at the surface and then to 150 meters deep for more
calibration. AL, the polar projects coordinator asks me is I want to work
outside for about an hour dropping this device into the water. It means
standing out in the cold and watching the ocean with a cable dropped in it
attached to the device. "Absolutely," I say, as the Flaming Trees or
Smashing Zucchinis, whatever CD my ex-roomie Ross (who, by the way, is a 23
year old smoker, drinker, baldheaded, tattooed, swearing, graduate student,
awesome, stellar guy,(he taught me these new adjectives)) plus the Dead
Kennedy's and every other band I can't pronounce is being played in the wet
lab where we are working is finally driving me insane. He is my ex-roomie
because after we left Palmer Station and dropping the researchers off
there, we all got our own private room for the next thirty days. However,
on the way home, we will be rooming together again, as we will put some
returning people on board at Palmer. I truly believe that one of the
greatest rewards of my experience such as this or just travel is the
opportunity to meet people who look different, act different, live in
different locations, but when we meet them, we find out that they are like
all of us. We need to be reminded of that as we continue to live in a
world that many times appears to be growing in different directions, each
direction based upon people differences, dislikes, and hatred. At least is
seems that way to me. I have become a firm believer in the universal
languages of music and laughter.
I have skipped lunch because we started hauling water again at noon so I
sleep from 1125 to 1145. Actually my eyes feel pretty good. The sounds of
the ship are intense. The CD player (those bands would drive anyone crazy)
the stern thrusters, (large jets of water to help hold the ship in
position,) the reversing of the props, the welding going on down below,
(maintenance on a ship is on going and doesn't stop just because we are
researching) all add up to a decibel lever that at times makes you want to
yell SILENCE, EVERYONE, RIGHT NOW - but you don't.
It is even colder now outside as we are tied to the bulkhead of the ship
with a safety line. The gate is swung away and Al and I push and manhandle
this large 7 foot high conductivity, depth and temperature device with a
thick electrical and hoisting cable attached to the side of the ship and
the crane finally lifts it over the edge. If one of us fell in without our
survival suit, death is going to come quick because of hypothermia. In
fact, if you fall overboard with a survival suit on, by the time the ship
gets turned around in these cold waters, the only reason they would look
for you is to get the suit back as one crew member told us. They don't
want to be involved in the government lost
and found paper work. I don't believe him.
It is getting dark outside and the snow is piling up. Someone has stepped
in and is filling my role as pump and filter watcher, because there is now
6-8 inches of snow on the aft deck and tomorrow we are supposed to lower
some buoys overboard. If we don't get the snow off the aft deck and it
freezes, we will be out tomorrow chipping it off with picks, so now I am
snow shoveling the snow out to the scuppers and off the aft end to throw it
overboard. I have also hauled 50 meters of cable for an hour today as we
tested the underwater ultraviolet radiometer. The snow has been thick and
at times as we hold position on day three using Global Positioning System
(GPS), the ships engines and thrusters, the pack ice seems to move back and
forth, sometimes inching its way towards us in the fog and snow. Thin films
of ice that look like oil slicks are forming on the surface of the water.
We call it skim ice. I swear that I can see it form and it looks like it's
clumping together to appear as a slimy-like cotton that bunches together.
At times I see large icebergs off in the distance that look s like ghosts
of a land that I don't know exists. I think of what the early sailors and
explorers must have thought upon seeing apparitions on the horizons and
realizing that early cultures and beliefs were based on folklore and were
centered around spirits, gods, and beliefs that today seem wildly
imaginative, I look out to the ghostly bergs and try to imagine if they
actually look like some design or made up creature in my mind. It is late
afternoon and getting colder. As I stand in my Helly Hansen rain gear,
float coat, wool gloves and Thinsulate mittens and my GIG HARBOR BASEBALL
HAT I think also of Shakleton and how he kept his crew together, crossed
the ice pulling life boats because they knew that they would eventually
need them, then spent a winter on the ice, set sail in the life boat and
crossed part of the southern ocean only to find themselves on an island,
but on the wrong side, and then climb over the mountains to find people at
a whaling station, and after 17-19 months of this incredible adventure, not
a single member of his crew died. This occurred in the early 1900's. It is
one of the most exciting stories ever told and very easy to read. And I
am still cold, especially my hands.
I skip dinner and go to sleep for 35 minutes. When I wake up at 1700hrs, 10
minutes before we haul water, I grab a cup of coffee and plan on grabbing a
bite to eat from the pantry at 1900hrs. I am not the only person working.
Two other people are sampling and running radioisotope samples and others
are using the water we gather to do their own sampling. It is going to be a
long night.
By ten, the snow is letting up but the temp is dropping now at -0.5 degrees
centigrade, however, the barometer is rising and has gone up 1 millibar in
the last hour. A large high is building towards us from the west. This
could also bring cold polar continental air. I am trying to download
barometric files to the laptop and to a disk to bring home. This could be a
neat classroom project where we compare the graphs of Antarctic barometric
highs and lows to the barometric highs and lows in the Pacific Northwest.
I probably need to stop rambling as some of you are probably saying "save
some for later", however this is so unique and there have been a number of
you that have said "keep telling us what is going on". The extra credit
question of the day is the following:
IF THE WATER IS -0.5 DEGREES CENTIGRADE OR BELOW FREEZING AND I SHOVEL SNOW
INTO THE OCEAN AND THE SNOW IS FROZEN WATER, WHY DOES THE SNOW MELT?
'Til later, thank you all for reading these reports and writing back.
Peace.
George.
