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.

Even in peak summer in the southern hemisphere, January in Antarctica still experiences freezing temperatures with wind chill, and we needed to dress accordingly. In addition to layering up, they provided each guest a pair of boots and a lifejacket to use for the cruise that would be used for the landings. The expedition staff would call us by group for us to board Zodiacs (a brand of rugged, inflatable boats), to take us from the ship to the shore. We were warned that landings could happen on rocky beaches with water up to the knees.

Red Rock Ridge: Adelie Penguin Colony

As we waited in anticipation of the first landing, I chatted with a friendly crew member who was visiting the shore with us about the ship like its power systems, tech stuff, and later it turned out that the fellow was actually the captain himself – I couldn’t tell since he was bundled up. He was with his wife, who took time off to join him on this particular voyage. We met them several times later on the cruise and they were both very nice people to talk to.

The expedition staff had chosen a rocky shore for us to make the wet landing. We stepped off the Zodiac into water that went about up to our shins, and they helped us out of the water. This was it, we finally made it.

The mountainous landscape challenged our preconceptions of Antarctica; instead of flat ice shelves, jagged peaks and volcanic rock rose before us, their exposed rock faces contrasting starkly against the white snow and ice. In some places, the ground was a mix of snow, rocks, and mossy patches of hardy lichen—the only vegetation capable of surviving in this extreme climate. Surprisingly, it wasn’t cold – the air temperature hovered around freezing, but without any wind chill.

The key highlight of this landing was the chance to observe an Adelie penguin colony. Adelie penguins are most southerly distributed penguin species, perfectly adapted to Antarctica’s extreme conditions. Their distinctive white eye-ring against black head feathers gives them a distinctive “tuxedo with goggles” appearance. The penguins showed curious interest in their human visitors, keeping a respectful distance while clearly observing us. We arrived during their breeding season, so we saw a mixture of adults and newly hatched chicks.

Contrary to popular animated depictions, penguins don’t simply slide everywhere. They use their feet to push themselves along when belly-flopping across the ice, and they genuinely waddle when walking.

Despite their adorable behaviour, the colony had a strong, unmistakable odour. The birds live amid their own waste, referred to as guano, which accumulates in their breeding areas. This guano is so pungent that one expedition staff member remarked, “if you get it on your clothes, you may as well just burn them.” Their guano stained the snow and the penguins themselves with orange patches. The term “guano” comes from the Quechua language of Peru and was originally used to describe the excrement of seabirds, bats, and seals that was collected for use as fertilizer due to its high nitrogen content.

Antarctic skuas patrolled the skies above the penguin colony, providing a glimpse into Antarctica’s harsh food chain. These large, gull-like birds are relentless predators, known for their aggressive tactics in hunting penguin eggs and chicks. With their powerful build and hooked bills, skuas can dive-bomb distracted penguin parents and snatch their vulnerable offspring in seconds. They also practice kleptoparasitism – stealing food from other birds – and will scavenge from carcasses when available. They’re are important components of the Antarctic ecosystem, though their predatory nature often earns them an unfair villainous reputation among visitors sympathetic to the penguins.

When we returned to the ship, we followed biosecurity measures to protect Antarctica’s fragile ecosystem, by washing our boots in a cleaning fluid to prevent the transfer of contaminants between landing sites.

Stonington Island: Traces of Human History

Our second landing brought us to Stonington Island, where the continent’s sparse human history became evident through abandoned research stations.

Despite Antarctica’s remote location and harsh conditions, humans have maintained a presence here for scientific purposes since the early 20th century.

Stonington Island houses two historic research bases: East Base (American, established 1939) and Base E (British, established 1946). These stations served as important outposts for early scientific exploration in Antarctica, supporting research in geology, meteorology, and biology.

Despite its remoteness, Stonington Island was not devoid of life. A few penguins slid across the ice while a solitary seal lounged in the distance. Penguins always seem to walk single file, and the ones in the back like to wait until their “leader” makes the first move.

Witnessing a piece of ice calve from the nearby ice shelf was another highlight. A massive chunk broke off, crashing into the water and creating a wave large enough to flip over before settling into its new position.

Reflections

Our expedition to Antarctica provided rare insights into one of Earth’s last truly wild places, especially having the opportunity to cross the Antartic Circle. After returning from the entire cruise, I had followed the cruise company’s ship tracker, and I haven’t seen it cross the Antarctic Circle on its other voyages so far, which made the experience more special, and that the crew was serious that they said how rare it was go sail this far south.

Each experience today deepened our appreciation for this extraordinary continent. As temporary visitors to this frozen realm, we left with only photographs and memories. We eagerly awaited the adventures to follow in the next few days.

Life Aboard an Ultra-Luxury Expedition Cruise Ship

The moment we stepped into our cabin, we knew this wasn’t an ordinary cruise. A bottle of champagne chilled in an ice bucket, while a bottle of wine and whiskey stood ready on the counter, part of the open bar included with the cruise. The cruise even includes free wifi.

The cruise line had outfitted us with essential Antarctic gear – a winter parka, waterproof backpack, toque, and stainless steel water bottle. There was even a pair of Swarovski binoculars ($1500 retail) for us to borrow for the duration of the cruise for wildlife spotting during our journey.

With 233 crew members attending to 262 passengers, the ship offered an intimate expedition experience. This nearly one-to-one ratio ensured personalized attention throughout our journey.

Preparing for the Expedition

Before setting off, we attended a briefing about the voyage, and a mandatory IAATO briefing on the rules on what we were allowed to do in Antarctica, like how only 100 people are allowed on shore at a time, and rules on maintaining distance to wildlife to avoid potential disease transmission.

Unlike typical cruises, there was no fixed itinerary—our activities in Antarctica would depend entirely on weather conditions. The expedition team informed us that conditions looked good enough to cross the Antarctic Circle, a rare opportunity even for them. On the second day at sea, the crew informed us that we finally crossed the Antarctic Circle, and as a fun thing, everybody received a certificate for this “achievement”.

To protect Antarctica’s pristine environment, we underwent thorough biosecurity checks to ensure we wouldn’t introduce any foreign organic material. Organic material, such as seeds stuck in hiking pants, could disrupt the fragile Antarctic ecosystem.  

Drake Lake or Drake Shake?

The Drake Passage, the body of water between South America and Antarctica, presents a fascinating demonstration of Earth’s natural forces. This stretch of water, where the Atlantic and Pacific Oceans meet, features the Antarctic Circumpolar Current – the most powerful current system on Earth. The absence of any landmass allows winds to blow unimpeded around Antarctica, creating the infamous “Roaring Forties,” “Furious Fifties,” and “Screaming Sixties” – terms that reference the increasingly powerful winds found at these latitudes.

The real challenge lies in the Drake Passage’s notorious waves. We prepared for seasickness with medication the night before, though in hindsight, the dosage proved too strong, leaving us groggy throughout the following day. Fortunately, we experienced what’s known as the “Drake Lake” rather than the “Drake Shake” – encountering strong waves only overnight before conditions improved by noon the next day.

Sea Days

With two full days at sea, the crew organized plenty of activities. We explored the ship, which featured several lounges for us to hang out in decorated with Antarctica-themed artwork from various artists. The top deck housed the Zodiacs — small boats we would use to reach the continent.

We also ate a lot. Each day, the lunch buffet featured a different cuisine, and the dinner menus always had items that changed daily. The food was delicious, as is usual for a cruise, but at the end of the day it’s tough for the food to be truly exceptional since the food is made in such high volumes, and more difficult to keep food at their freshest given the time at sea. The open bar was nice too – I looked up a list of common cocktails and ended up trying a different drink every time. Even better was that the bartenders were so good that I’ve been having trouble getting the same cocktails at the same level of quality since I’ve been back.

We toured the bridge, where crew shared stories of recent celebrity visitors including Neil Degrasse Tyson, William Shatner, and Scott Kelly as part of the Space2Sea.io program. One crew member quipped that if he got a dollar every time a guest mentioned hitting an iceberg, he’d be rich.

We also got to tour the submersible garage. They have two subs on board, one named 71-1, and the other 71-2, with 71 representing the percentage of the earth covered in water. Just like how it’s hard to resist joking about hitting icebergs, it was also tough not to mention the OceanGate fiasco too. A sub excursion costs $1000 USD per person for an hour-long tour, so we opted to skip that particular adventure.

Learning About Antarctica

The cruise also offered lecture series, that provided valuable context for our upcoming Antarctic experience. We learned about the Antarctic food chain, where krill forms the foundation of the entire ecosystem. We studied the different penguin species we might encounter – Adelie, Gentoo, and Chinstrap – and learned about the hunting strategies of orcas, who work in teams to create waves that wash seals off ice floes. We didn’t go to all the lectures though since some felt like going back to school, after all I’m on vacation!

Experts explained various ways to define Antarctica’s boundaries – from the obvious land and ice borders to the more complex Antarctic Convergence, where warmer sub-Antarctic waters meet colder Antarctic waters. There are other geometric boundaries too such as simply using the Antarctic Circle, or just defining the borders as all land and ice shelves south of 60 degrees south latitude, which is what political treaties use.

Between lectures, we passed time with games of Scrabble, though our enjoyment was somewhat dampened by the grogginess of the seasick medicine, and the feeling we might be getting sick due to the past days of being in transit – a couple of people sounded sick too on the flight to Ushuaia. We focused on rest and hygiene, determined not to let illness prevent us from exploring once we reached the continent. We would have been very disappointed that if after everything we had been through so far, to be bedridden with a fever, would have totally ruined the trip. Cruises are known to quarantine people, and that is a policy that predates COVID.

First Glimpse of Antarctica

Finally, after two days and two nights at sea, we finally reached Antarctica. Icebergs drifted past our balcony, marking our arrival.

Looking through the binoculars, I spotted our first penguin in the distance, a moment that marked the true beginning of our Antarctic adventure.
