November 13, 1998
WOW the last few days have flown by and have been chock-full of neat
experiences. The neatest experience was the trip to Granite Harbor on
Wednesday.
PREPARING TO FLY
The night before, the fish-group gathered together all that we
would need for our trip: 5 coolers , 4 of them fitted with
battery-operated air-bubblers to keep the fish alive until we could
get them back to the aquarium, 2 cylindrical cages made out of
plastic-coated chicken-wire to hold some of the fish in the water
until we packed them up to go, the jiffy-drill with bit extensions
allowing it to drill 10” holes through about 8 or 9 feet of ice, gas
for the drill, fish hooks, rubber-worms for bait, hand-lines, ice
axes to chop away at the ice, a hand-held radio (to communicate with
the helicopter after we were dropped off if need be), a small camping
stove with fuel, eat-out-of-the-bag freeze-dried meals like chicken
fettuccini and beef stroganoff, cocoa and cup-of-soup mix, (we forgot
cups and bowls however), a pot, plastic eating utensils, buckets, a
hand-operated bilge pump to help fill the coolers with water from the
jiffy-drill holes, small nets to scoop the slush out of the fish holes
as the surface water started to freeze again, and probably some other
things that I forgot about. It was a lot of stuff and the next day we
needed a pick-up truck to bring it all down.
At about 8:00 in the morning, I took some Bonine, a tasty,
chewable pill that prevents motion sickness without making you drowsy.
I had heard bad things about bumpy helicopter rides and I didn’t want
my first helicopter experience destroyed by feeling nauseous.
(However, I didn’t need it since it was a very smooth flight.)
At 8:30 we gathered at the lab with the gear we had prepared the
day before and with our own personal gear to head down to the
helicopter pad for our flight to Granite Harbor. I brought my water
bottle which I filled with very hot water and put it in my camera bag
to help keep my camera warm so the batteries wouldn’t lose their
power. (Cold temperatures sap the energy out of batteries. WHY?) I
also protected one camera by keeping it under my coat. I also
brought a candy bar and lots of film (but just barely enough); and
chapstick, sunscreen and sunglasses to protect myself from the
ultraviolet rays which can quickly burn or cause “snow-blindness”. We
each also had to bring an extra supply of our cold weather survival
gear, just in case we got stranded in a blizzard out at Granite
Harbor. It is a little less than a hundred miles to Granite Harbor
and the weather can quickly change so we had to be prepared just in
case. The helicopter was scheduled to pick us up six hours after it
dropped us off on the ice and a lot can happen to weather in 6 hours.
It was overcast in McMurdo; the tops of the mountains were invisible
in the clouds. We wondered what it would it be like at Granite
Harbor. The helicopter also carried an emergency survival bag to drop
off with us when it landed . It was full of supplies (tent, sleeping
bags, emergency food rations, etc) to help us survive until help could
come if a storm suddenly stranded us here.
Before boarding the helicopter we weighed ourselves and all our
gear. (Why do you think it was important for the pilots to know the
total weight?) We also were fitted with helmets equipped with
earphones and microphones so we could hear and speak with the captain
in the noisy helicopter. The helicopter blades were so noisy that I
had to put my fingers in my ears when we were outside if my helmet
wasn’t on.
At about 9:15 we were off. I was very excited. I always love
the “skua’s eye view” of the world. It really helps to put things in a
grander ecological and geological perspective. One of the amazing
things that struck me as we flew along was how the mountains seemed
nearly smothered in a blanket of white, with just their peaks poking
out above the glaciers and snow-cover. Some of the ice must be
thousands of feet thick. The other thing that struck me was that even
though the frozen sea seemed limitless from the ground view, the ocean
really wasn’t very far away; we could see it in the distance about 10
or 15 miles away. For a skua that is probably not very far. But if a
penguin can’t find any seal holes to dive into, it would be a pretty
long walk for him to find breakfast. I guess that’s why there aren’t
any penguin colonies this far from the ice edge. When we flew over the
ice-sea edge I looked for penguins and whales but couldn’t see any.
GRANITE HARBOR
When we landed at Granite Harbor I was awestruck. How can I put
into words the spectacular majesty of the place. Unfortunately the
attached digital pictures cannot begin to communicate the feeling of
awe and humility and enthusiastic appreciation of what I saw. A few
individual pictures cannot record the full expanse that overwhelms and
envelops a tiny person who is plopped into the middle of such a grand
thing. Even now as I think about it in my mind’s eye, a lot of the
experience and the accompanying emotions are lost. It can only be
appreciated fully at the time and in the place, and even then it is
not a full appreciation. I would have to go back for days and days
and walk for miles and miles listening, thinking, rejoicing, praying,
watching, smelling, feeling to even begin to take it all in. The
first hour and half we were there we all just walked around savoring
the entrancing beauty around us. So what were some of things we saw
and heard?
Huge sculptures of ice, pressure ridges of blue ice slowly
shoved up as immense slabs by the forces of tides and glaciers --white
on top, glazed and textured by melt and wind, blue underneath. Melted
and wind blown into bizarre shapes. Icicles dripping into angular
caves.
And in the distance: these sculptures were placed in an
overwhelming setting, a huge sweeping valley filled with a glacier,
edged by mountains, a huge frozen bay rimmed by snow-capped mountains,
a steep cliff plummeting into the frozen sea which seemed to go on
forever in one direction, a gradual slope, strewn with huge glacial
boulders of granite rounded and dropped off by glaciers in the
geological past.
Here among these boulders was a crude boulder shelter, merely 15 feet
by 10 feet or so, hidden behind some larger boulders which housed 6
men on their way back to Cape Evans after they had been stranded at
Cape Adare for several months during a very long, cold, dark winter
in 1912. They were stranded in a snow cave no larger than the
boulder shelter at Granite Harbor when their ship couldn’t come to
pick them up because the ice was frozen solid. They rationed their
food supplies. At the end of each month they each had a treat of 25
raisins. Once or twice a week they had a little chunk of chocolate.
When their food supply ran out they ate nothing but the meat and
blubber of seals and penguins. Once they received a surprise treat
when they found 12 undigested fish in the stomach of a seal. At night
they had nightmares about food. In their dreams only one of them
managed to eat their scrumptious banquets; the others all woke up up
before they could enjoy their dream-feasts! What torture! Two of them
got very bad diarrhea; that must have been an extreme nuisance in the
bitter wind and cold of winter. Those two almost died. They burned
seal blubber to heat their shelter. An old dried seal hide is still
visible on the ruins of their shelter at Granite Harbor. When they
finally made it back to Cape Evans the following summer, their clothes
and skin were permeated by the black oil of the burned blubber. Their
clothes had started to rot on their bodies. I complain when I can’t
sleep because someone is snoring; imagine what smells, sounds,
cold, wind and other conditions they had to endure as they tried to
sleep and survive! I wonder what they talked about while they were
crammed together for months in the cold and dark.
THE WEDDELL SEALS
To me, the most surreal part of our expedition on Wednesday was
the sounds of the Weddell Seals. Eerie, ethereal musical wails, boops,
and grunts came from below us in all directions. Unseen singers
swimming under the ice, rapidly getting closer and closer until they
sounded like they were right beneath us, and then off into the
distance. How can I describe these sounds in words? I can’t; but I
do seem to remember an Internet website where you can hear their
calls. If anyone can find this site please e-mail me and let me know
and I’ll pass it on to the other journal readers.
Among the beautiful pressure ridges were cracks in the ice.
These had frozen over, but in some places the seals had used their
specialized teeth to keep the holes big enough for them to get up out
of the water onto the ice to soak in the sun and to nurse their pups.
(How do you think they managed to get their megabodies out onto the
slippery ice?) I was standing right next to one of these holes
when I suddenly heard some soft splashing and loud blowing noise as a
seal pup stuck its head out of the hole. He looked at me curiously
and went back under. As I stood there awhile he and another pup kept
coming back. We left the area just in case our presence was
preventing them from coming out. Once I saw the sleek, dappled body
of one of the adults gracefully ballet by beneath the crack
A little later I saw one of the pups out on the ice. He was
moving towards me wailing and groaning, sounding sort of like a lamb,
as if he was calling to his momma. Sometimes his voice sounded like
Chewbaca in Star Wars. I sat down on the ice to watch. He kept
getting closer and closer, calling out. I think he thought that any
big dark shape on the ice might be his mom, but about 20 feet away it
seemed like he suddenly recognized that I wasn’t a seal , he stopped
and turned around with a protesting groan. He wiggled away with
maggot-like movements and I moved on. A couple minutes later he saw
me moving again and started coming towards me; so I sat down again to
watch. What a cute puppy-face seal pups have! Soon his Mom poked her
head out of the hole in the ice and called to him. He immediately
stopped and went towards her voice whining all the way. She submerged
and he quietly slid into the water behind her. About an hour later
when Sierra was fishing in the hole we saw the mother nursing her pup
out on the ice about 50 feet away. Occasionally the momma would call
out with a peculiar series of muffled grunts, her head bobbing up and
down. It was quite a scene.
FISHING AFTER LUNCH
Since we didn’t have the fish hut or the meter-wide hole for
fishing, several smaller holes were drilled with the jiffy drill along
the frozen ice crack where the ice was thinner. Then 3 of us
positioned ourselves at the holes and started haulin’ in the fish. It
was a great day for fishing. My job however, was not fishing. I was
assigned to protect the fish that were caught. Remember if the water
gets too hot or too cold the fish can die so I went around to all the
coolers checking the temperature and adding cold or warm water as
needed to keep the fish within about -1.7 degrees Celsius and + .5
degrees Celsius. I also had to change the water when it got dirty and
change the batteries of the air-bubblers when they started to lose
their power. If there were too many fishes in one cooler I needed to
transfer a few to a cooler with fewer fishes. Out of the 40 or 50
fish we caught only one died by the time we reached the aquarium back
at McMurdo so we all felt good about that.
WEATHER
Even though it was overcast in McMurdo all day, the weather at
Granite Harbor was sunny and warm. It was +.5 C, a smidge above
freezing. That made the surface of the ice very slippery (WHY?). We
all took off our parkas and didn’t mind handling the fish with our
bare hands because it was so balmy. But just before we packed up to
leave, the wind picked up, and we immediately ran to don our warm
gear. Although I wore my sunglasses all the time except the first 15
minutes when I was so entranced that I forgot, and occasionally when I
was taking a picture, I still had the beginning symptoms of
snow-blindness at the end of the day: a head-ache behind the eyes and
blood-shot, gritty-feeling eyes. I am so glad I wore the glasses most
of the time. I hear that snow-blindness is torturously uncomfortable.
(It is caused by the sunlight coming from above and also reflecting
off the snow. The ozone hole here in Antarctica means there is more
harmful ultraviolet (UV) light which makes it even worse.
THE END OF THE DAY
At the end of the day I was so exhausted that I fought to stay
awake during a very interesting lecture on the ecological effects of
pollution in McMurdo Sound and then went straight to bed at 8:30. It
was a GREAT DAY!!!!!!!! One day like this is worth many in the lab!
Well I guess I’ll send this journal entry along and tell you
about the labwork over the last few days tomorrow.
Until then, I hope you have a good day and do something good for
someone.

A scene at Granite Harbor. The snow in the mountains in the background is a glacier. You can see a seal as a dot in the snow and a frozen-over seal-hole in the blue ice in the forgeround.
A seal pup pokes his head up through a hole in the ice just a few feet away. Granite Harbor.
The pressures of the glaciers and the tides have forced the ice into these beautiful sculptures called pressure ridges.
Sierra, Jeb and David use the jiffy drill to drill through the ice along a frozen-over ice crack. Look at how huge the ice formations are. It was a warm enough day to shed our parkas.
Sierra looks cool in black as she fishes in a hole that the seals excavated along an ice crack. The water here was over 50 feet deep. Notice the cooler to keep the fish at the right temperature. In this photo she is using a han dline to fish. You can see the mother Weddell Seal and her pup in the background. They are just relaxing in the sun; they aren't dead.
