On our Antarctic excursion, the first sight of
glaciers outside our cabin window was totally exhilarating. Later that morning,
as we skimmed the ocean’s surface in a Zodiac from the expedition ship to our
first continental landing at Portal Point, the peninsula’s glacial plateau came
ever closer. Beautiful slopes of snow and ice and a spectacular rocky peak of a
nunatak rising out of the glacial
masses was simply breathtaking.

For me, seeing the indescribably beautiful ice of Antarctica was emotional. The enormous ice sheet stretches as far as the eye
can see and is even visible from space. Viewing this distinctive sight seemed
surreal, unlike anything else on Earth.
amazing visual that brings most visitors to Antarctica—the full kaleidoscope of
colors, shapes, and sizes. Shades of green, blue, and white. Some icebergs smooth
and glistening; others with a grainy or crunchy appearance. Pointy, triangular,
chunky, or flat on top. Small bits of brash
ice or giant islands moving slowly through the water.

But if you listen closely, you realize that the ice
has a voice. The most noticeable sound is the loud crack heard when a chunk
separates from a larger mass and falls into the ocean, a process known as
calving. If the chunk is very large itself, the noise can be almost
deafening—and the situation dangerous. But there are more subtle sounds such as
the whoosh of gases releasing from floating bits of ice or the gentle swishing
of movement in the ocean.
Touch a piece of glacial ice, and you’ll immediately
feel a stinging cold. Glacial ice is denser and has larger crystals than
ordinary ice, so it feels much colder and melts much more slowly. Put a piece
in your drink, and it will last all day.

|Sharp points are common since pieces of ice often break off|
from large icebergs such as this pure white beauty.
Another sensation created by icebergs surprised me.
At times, when we were floating in a Zodiac, it felt like the sea was shifting
under the weight of these enormous ice sculptures. Since most of an iceberg is
underwater, the whole structure could heave with the rolling waves. One day, as
we approached Cierva Coves at the southern end of Trinity Island, our Zodiac dodged
brash ice while we watched icebergs surf the swells, rising and falling with
ominous force. Needless to say, we kept our distance.
From our guides we learned that even though many
glaciers are retreating and there is 40 percent less ice worldwide than 50
years ago, sea ice such as in Antarctica is advancing and as a whole is
increasing in volume (surface area and thickness). Still warmer temperatures
affect the food chain and wildlife in different ways, which is an ongoing cause

The ice of Antarctica is a wonderland of incredible beauty.
To me, the experience felt like skimming through a dream—like Alice in the
rabbit hole viewing impossible sights that couldn’t be imagined unless you were
there. I never tired of watching the infinite ice forms move through the ocean water. What a thrill it was to discover this magical land!
