- We arrived at Davis Station are in
the early morning. The sunrise was very nice, and the weather
was looking good in general, albeit a bit cold and windy. We
ended up south of the station, in the Vestfold Hills area. There
were lots of icebergs, and the area is mostly uncharted, so the
captain deployed a Zodiac with a depth sounder to help with navigation,
then the expedition team found a good landing site on Zolotov
Island.
-
- The sea was a bit choppy, so getting
on the Zodiacs was tricky, but we made it ashore unscathed. Once
there, the barren, rocky landscape was very other-worldly. One
thing that stood out immediately was that there were dead Adélie
penguins everywhere. Hundreds of them, perhaps more, scattered
about in various stages of decay and mummification. The environment
here is cold and dry, similar to the dry valleys in the Ross
Sea area, so the dead penguins can remain for decades without
decomposing. It was fascinating to walk around and see so many
penguin carcasses. There are upwards of 23,000 breeding pairs
of penguins that come here to breed each year, so the area has
seen countless generations of penguins. The ground was mostly
very rocky, but in other spots the vast amounts of guano have
piled up over the years, making a soft soil. There were some
Adélies still here, many were molting, getting ready to
head back out to sea for the winter.
-
- We walked up a rocky hill that had
the most interesting and diverse geology, with plenty of tafoni
holes in the rock. These holes are believed to have been formed
by a complex interaction of physical and chemical weathering
processes, including salt weathering and cyclic wetting and drying.
At the top, we had a great view of a small lake, and in the distance,
the Sørsdal Glacier. The weather started to shift and
clouds began to roll in. The sea was quite choppy for the Zodiac
ride back to the ship.
-
- In the afternoon, the team arranged
a second trip ashore, this time to a small, unnamed cove on the
Antarctic mainland. It was cold and windy with about a 4km Zodiac
ride to the landing site. This place was the most other-worldly
spot we've encountered. Very rocky, with almost no life whatsoever,
other than 2 Adélie penguins that greeted us when we came
ashore, and a small patch of black lichen/moss. That was it.
Otherwise, it seemed utterly devoid of life. No signs of previous
penguin colonies, nothing. There were a few frozen ponds, and
a hill we were able to climb to get a better view. We got to
the end of the walk, which was along the shore of a bay which
was mostly frozen, with a view of the Sørsdal Glacier.
-
- This was the last excursion in Antarctica
proper for this trip. It has gone so fast, but what a privilege
to come to East Antarctica and visit places seldom (or never)
visited by people before.
-
- There was some drama on the Zodiac
ride back to the ship. Another Zodiac flagged us down and informed
us the captain had given orders to head back to the landing site
because there was a big ice calving event that produced a tsunami
wave. We turned around and waited it out for a while, then as
we continued back, we ran out of gas. This was only a minor inconvenience
since there was a spare tank on board that just had to be switched
over. As it turns out, a big chuck of the glacier face had calved
off and sent out a wave that caused a giant iceberg to start
moving quickly (3-4 km/h) in the general direction of the ship.
It's also possible that it was the iceberg rolling that caused
the glacier to calve. Which happened first is a bit unclear.
The fast moving iceberg eventually became grounded in shallower
water.
-
- The captain did a great job of expertly
keeping everyone safe and ensuring the ship was not impacted
by the iceberg.
-
- At sunset, the sky was almost completely
overcast, except for a clear spot along the horizon. As the sun
dipped down into that clear area, the light was fantastic. I
was hoping for another green flash, and it happened. It lasted
a long time, too. Several seconds because of how slowly the sun
sets at this latitude.
