Gentoo Penguin Colony at Neko Harbour

Our visit to Neko Harbour brought us face-to-face with a colony of gentoo penguins. Due to the colder, windier conditions, many of the adult penguins were sitting tightly on their chicks, shielding them from the elements.

The penguins cope with Antarctic temperatures through a combination of dense feathers, thick subcutaneous fat layers, and specialized circulatory systems that minimize heat loss in their extremities.

Gentoo penguins are the fastest of all penguin species, capable of reaching speeds up to 36 km/h underwater. Watching them swim was almost like seeing a laser beam darting through the icy waters.

They still look goofy when they walk on land, and this awkward movement on land contrasts sharply with their remarkable swimming abilities.

We also observed their well-worn “penguin highways” – small, carved-out paths in the snow they use to travel between their colony and the beach. These highways are formed by the repeated passage of penguins, gradually compressing the snow into defined trails.

When crossing these highways during our hike, we followed strict instructions to give the penguins right of way and to avoid stopping at any intersections that crossed their paths. We observed the gentoo penguins’ distinctive waddling gait as they travelled along these highways.

Reaching the colony required a challenging uphill walk. The increasing wind made it even more difficult, and by the time we reached the top, my face had gone numb. However, the effort was worth it, as the higher vantage point provided a sweeping view of the harbour, with icebergs floating in the bay below.

Across the water, a massive glacier towered in the distance with massive crevasses. Every glacier, ice shelf, iceberg, etc. was like a natural sculpture.

Wildlife Spotting in Paradise Bay

In the afternoon, we embarked on a zodiac cruise around Paradise Bay. The purpose of this excursion was to get closer to the inactive research bases in the area and to observe wildlife from the water.

During our cruise, we spotted a small vessel in the distance. Our guide informed us that it was likely a private expedition and noted that such a small boat would have faced a much more challenging journey across the Drake Passage than our ship. While our crossing of the Drake Passage took approximately two days, a vessel of that size might require 8 to 10 days to navigate the same waters, not to mention being thrown around a lot harder in the waves.

The wildlife sightings began with more gentoo penguins resting on ice floes. It’s remarkable to see these penguins in these places, so far from their colonies. They have adapted to life in Antarctica through specialized features including dense waterproof feathers and the ability to drink salt water. Their bodies contain special glands that filter excess salt, which they expel through their nasal passages.

Our cruise transformed into an impromptu whale-watching expedition when we encountered several humpback whales swimming nearby.

We paused to observe them, and soon discovered that we were surrounded. As we focused on one pod of whales, another would surface elsewhere, reminiscent of a game of whac-a-mole. The whales appeared curious about our presence, with one even swimming directly underneath our zodiac, briefly making me worry it might tip us over. Fortunately, these gentle giants seemed aware of our presence and moved carefully around us.

While we saw many whales, none of them breached as dramatically as the whalewatching tour brochures often depict. Our guide explained that breaching is not as common as people expect, making it a rare sight even on dedicated whale-watching excursions (very misleading in those whalewatching brochures). In 20 to 30 minutes, we saw more whales than in the entire expedition combined.

Seals were also scattered across the icebergs, resting and occasionally glancing at our boat.

Each iceberg presented a different shape, texture, and blue hue, appearing as naturally sculpted art installations drifting across the bay. The distinctive blue colour results from the ice’s unique crystalline structure which absorbs red light while reflecting blue wavelengths. Some icebergs contain ice that fell as snow thousands of years ago, preserving ancient atmospheric conditions within their frozen layers.

We spent so much time watching the whales, and the other wildlife that we ran out of time and didn’t even make it to go see the abandoned research bases. This was totally okay, seeing the whales was better than doing a drive-by of the abandoned research base.

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.
