Antarctic Expedition, Day 4: Fish Islands

The fourth day of our Antarctic expedition brought us to the Fish Islands, where we again get to partake in a zodiac tour. As part of IAATO regulations, only 100 visitors are allowed on shore at any given time. With 262 guests aboard, we had been separated into three groups, with each group rotating for who went first. This had been the arrangement for every outing thus far, and today, our group was scheduled first, requiring an early 8:00 a.m. start.

Zodiac Tour Through Ice and Water

Our excursion took place entirely by zodiac, allowing us to navigate the icy waters and get a closer look at the Antarctic terrain. The weather was exceptionally clear, offering remarkable visibility.

As we floated through the frigid waters, the landscape around us displayed a fascinating variety – flat, smooth snowbanks, jagged cliffs, towering icebergs, and sprawling glaciers.

One of the more intriguing phenomena we observed was “scalloping” on icebergs. This process forms small, golf ball-like divots on the surface of the ice, created by the uneven melting. I tried looking into the science, but it’s actually quite technical, requiring an understanding of fluid mechanics.

Some icebergs even featured long icicles, a testament to the dynamic and ever-changing nature of Antarctica’s frozen landscape.

In some places, the water was remarkably still and reflective, creating mirror-like surfaces that doubled the visual impact of the surrounding landscape.

Humpback Whale Encounter

As we ventured further, we spotted several humpback whales surfacing in the distance. Each whale’s fin pattern is as unique as a human fingerprint. A website, HappyWhale, allows citizen scientists to upload images of whale fins, contributing to global tracking efforts and expanding our understanding of whale migration patterns.

We watched as they gracefully moved through the water, occasionally expelling misty bursts from their blowholes.

Lounging Crabeater Seals

Seals were another common sight throughout the day. We encountered a few crabeater seals resting on ice floes. Despite their misleading name, crabeater seals primarily feed on krill, using their specialized teeth to filter these small crustaceans from the water.

Up close, these seals are surprisingly cute with their expressive faces that appear to be smiling when relaxed. Their primarily white coats with scattered dark speckles help them blend into the snowy environment. When resting on ice, they often adopt a contented pose with eyes half-closed and flippers positioned as if waving to passing boats.

One of the seals rolled over lazily, seemingly indifferent to our presence. The narrator pointed out that it was a female, identifying it by its ventral slit.

It was a simple but fascinating moment – one of those times when I’m reminded how cool it is to watch animals just doing their thing in the wild.

Gentoo Penguin Spotted

We also saw our first gentoo penguin, perched alone on an iceberg.

The moment was made slightly awkward when one of the guests on our zodiac made an odd catcalling noise toward the penguin only to be swiftly shut down by our zodiac driver.

Sailing Onward

After returning to the ship and setting sail for our next destination, we continued to spot small icebergs with seals lounging on them. One particularly interesting sight was a seal resting on an ice floe marked with what appeared to be either guano or blood stains – perhaps evidence of a recent penguin meal.

The crew has yet again planned another successful excursion allowing us to again see another dimension of Antarctica we did not see before.
