22 October, 1996
Subject: Re: Journal 22 October 1996
Live from the Polar Duke in the Gerlache Strait
Location: 64.14S X 61.51W Wind Speed: 7.0 m/sec
Boat Speed: 0.0 Knots Wind Direction: 173.3 degrees
Boat Heading: 208 degrees Barometer: 975.67 mb
Humidity: 76.3 % Air Temp.: -1.1 C
Salinity: 33.7 0/00 Water Temp.: -1.3 C
General Weather Conditions: Beautiful day until about 1800. This was
the first time we have seen the mercury climb above the zero mark. The
winds began howling (katabatic winds) at 1800 and by 2000 the wind speed
had accelerated to 23 m/sec!
Today, we have reason to celebrate! We are doing our last diel! To make
it a memorable diel, the pump broke! This slowed things up from 2200 to
0200, but we managed to get our samples.
We had some really beautiful ice today. There was one football field sized
chunk that had beautiful carved arches that went straight through the
iceberg. The colors, shades of blue that are more typical of tropical
environments, were dazling.
Time for more questions and answers:
The first two are from Alison and Jill from Montezuma High School in Iowa:
1. Do you get to eat well-rounded meals or is the food like T.V. dinners?
The meals are well-balanced but are becoming boring and monotonous. The
selection doesn't vary much and as I mentioned earlier, the crew of the
ship, including the chief steward is Norwegian. This means that we have
been living on a Norwegian diet, which has two basic food groups, fish
and potatoes. We have also run out of various staples like peanut butter
and yogurt, we haven't had fresh vegetables for the last two weeks and I
never thought that running out of oatmeal would constitute a crisis. Lunch
is probably the best and largest meal of the day which is typical of
most European countries. There is a hot and cold buffet and my favorite
item is the smoked salmon.
2. Have you ever seen any green plants on the land?
Although we haven't spent too much time on land, I think that I can state
with a fairly high degree of certainty that this landscape is
overwhelmingly WHITE! This is because only 2 percent of Antarctica's
5.4 million square miles is free of ice. There are only two native vascular
plants (vascular plants have xylem and phleom which are tissues that
circulate liquids), are able to grow south of 56 degrees. One is a grass
and the other is called a pearlwort. Moss is also found, but the most
common plant, is one that is able to tolerate the extremely cold and dry
conditions these are lichens. Lichens are a combination of algae and
fungi. The two organisms have a mutualistic relationship in which both
benefit. The fungi supplies the home and the algae makes the food. About
150 different lichens have been found around the area of the Antarctic
Penninsula.
These are from my Brumagim Buddies at Oakdale Elementary in Virginia:
3. On an average, how long does it take to get our e-mail?
We are able to send out and receive e-mail twice a day. The mail goes
out at 1100 and 1900 each day. Therefore if you write to me after 1100 I
won't get your e-mail until after 1900. Sometimes the system becomes
overloaded and mail may not be received. I also suspect that some mail
is lost (in the ozone).
4. Are you finding your work interesting? Are your findings what you
expected?
The work itself involves long hours and lots of hard physical labor. The
labwork has been interesting, I have learned some microbiological
techniques, for example, I have made many slides of bacterial cells.
Some of these slides were counted on the ship with an epifluorescence
microscope. The counts are used as a measurement of cell abundance, it
gives us an idea of how many bacterial cells were present in the water at
the time that the sample was taken.
Most of the samples (all of the filters, the rest of the slides, ect) we
collected will be analyzed at the University of West Florida and at other
labs in Texas and Oklahoma. We won't have any results from most of the
experiments until weeks after we return to the states.
What is really important and exciting is that nobody has done this kind of
work in Antarctica! Maybe we will make some important discoveries!
These are from the sixth graders at Oak Hill:
5. Are you finding lots of information on plankton?
We have collected lots of bacterioplankton, but as stated in the question
above, most of the important information will be revealed once these
samples are analyzed.
6. Is there a television on board your ship?
Yes, there are two T.V.'s on board. One in the lounge and one in the day
room. They are both hooked up to VCR's and are used mainly to watch movies.
When the ship is in range of Punta Arenas, Chile, we will be able to pick
up Chilean stations!
Thanks for the questions!
