1 February, 1998
Happy February from Antarctica! When I woke up this morning, the night
crew said I missed one heck of a storm! I guess it snowed and the wind
blew so much that you couldn't see anything in front of the ship. They
said the seas had waves high enough to crash on the back deck (where we
normally put out all the gear) and that they could see the waves out the
dry lab portholes (where we normally work). They also said that the boat
rocked back and forth A LOT! I must have been sound asleep, because I
never noticed! Several people said they rocked enough in their beds that
they woke up. Needless to say, the boat slows down considerably in
situations like that, and we don't deploy any equipment when it isn't
safe out back. By the time I woke up, things had calmed back down and
the sun was trying to peek through the clouds.
I saw a new bird today! An Emperor penguin! I wouldn't have known it
was out there, but I received a telephone call to look out the starboard
(right side of the ship) portholes. He definitely was taller than the
Adelies that we have been seeing, but he was too far away to notice the
characteristic yellow color under the chin. I hope to see another one
when I have my binoculars handy!
Speaking of wildlife, yesterday's question was: "What types of wildlife
would you expect to find in the interior of the continent?" There are no
land vertebrates in Antarctica. Even the penguins, seals, and birds that
are found around the coast are technically considered marine animals
because they depend on the sea for their food. There are, however, a few
living organisms that can be found on the continent. Antarctica has at
least 200 species of lichens, over 100 species of mosses and liverworts,
more than 30 species of macrofungi, 2 species of flowering plants, and
many species of algae. The largest of these plants are found around the
Antarctic Peninsula -- some banks of moss are over a meter deep. Both
types of flowering plants are very small and they are restricted to the
islands to the west and north of the Antarctic Peninsula. One of the
most unusual plant habitats can be found in Victoria Land, where some
plants live within large-grained sandstone rocks . . . actually growing
between the sand grains!
The largest native land invertebrate on the Antarctic continent is a
tiny, wingless midge about 1/4 of an inch long. There are also several
other types of insects that can be found, which include springtails and
tiny mites. Most Antarctic insects live under rocks and stones in the
soil and among lichens. Springtails are especially common around penguin
colonies. They are black and shiny, and they jump around. No insects in
Antarctica have wings, but they all do have a special "anti-freeze" in
their cells that is a lot like the liquid that we put in our car
radiators for the winter. In Antarctica, there are very few different
species of insect. However, in some areas there may be millions of
insects per square yard!
Of course, there are lots of birds around the coast of Antarctica and
over the Southern Ocean. Many varieties of albatross and petrel can be
found; along with shearwaters, gulls, terns, and skuas (to name a few).
The South Polar skua is one of the few species that actually breeds on
the Antarctic continent. It also has the distinction of being the
world's most southerly bird -- at least two have turned up at the South
Pole! These birds are known to fly very far from home. Some South Polar
skuas have been flown all the way up into the Northern Hemisphere. South
Polar skuas are predatory birds that often prey upon penguins and other
colonial seabirds but also feed at sea on Antarctic krill. (What other
types of critters, besides krill, can be found in the waters surrounding
Antarctica?)
Thanks for all your email. I hope you're enjoying these journals as much
as I enjoy writing them. Look for more pictures sometime early this
week!
