Exactly 22 hours after leaving Ushuaia, Argentina, which calls itself ''the end of the world," the expedition ship Fram reached the Southern Ocean, which circles Antarctica — the real end of the world.
The captain's public address announcement interrupted the lecture on that frozen continent's ecology, but the passengers cheered.
We were little more than halfway to our first trip ashore. That meant we might be facing another night and day like the first one — grabbing for corridor handrails or the backs of chairs to brace against the exaggerated rolling of the ship in what can be the planet's most hostile 600 miles of sea.
But our progress also meant we were that much closer to a continent so massive that if you put the United States on top of Antarctica, there would be more than a million and a half square miles uncovered. Meanwhile, the United States would be sitting on ice more than a mile and a half thick.
We'd be landing in early summer — that's winter in the Northern Hemisphere — when the temperature would climb to freezing on only one of our four days there.
We could barely wait.
Our patience was tested the next morning while still approaching: The ship motored into a mini-blizzard whose tiny snowflakes turned to sleet so thick the Fram seemed fogbound. The deck became slippery with snow.
But once the ship passed the storm and reached the islands off the Peninsula, the 122 passengers understood what Dorothy felt as she opened the farmhouse door:
We found ourselves under a brilliant blue sky in a majestic land, its horizons defined by mountains and perennial winter.
All around us were huge granite peaks whose jagged outlines were softened by thick coats of snowdrift. Icebergs glistened pearly white or an eerie neon turquoise, or both. Irregular clangs and chungs sounded throughout the 373-foot-long ship as its hull plowed through drift ice, remnants of building-sized icebergs still within view.
We could see penguins leaping above the surface of the clear sea for fractions of a second before darting ahead, underwater.
The eight-day voyage had become an expedition. And on expeditions there are often surprises.
"All stated times and activities are changeable due to weather conditions or other circumstances out of our control," the daily agenda reminded passengers.
That's why on Day Three the captain slowed the Fram in order to trail three fin whales. And that's why the much-awaited scenic cruise in the eight-passenger landing boats was canceled twice. As we swarmed the three observation decks to stare at a monster slab of ice a mile or so in front of the bow, the captain explained over the P.A. systems:
''Well, this is what happens when a 500-meter-wide iceberg enters a 550-meter-wide channel. We cannot send in the little boats because they must always be near the big ship.
''We will turn and go the long way to the other end of the Lemaire Channel. And tomorrow, we will see if the iceberg has taken a holiday somewhere else."
But the next morning the iceberg had not moved on, thus canceling one of two scheduled landings on Day Six, a day that dawned as bleak as our collective mood became.
And then surprises happened.
The layers of gray clouds suddenly blew away to reveal another sunny day. Said the assistant expedition leader, Ina Schau Johansen:
"If we get a third day like this, then don't ever come back here, because we will never get it this good again.''
She wasn't joking. On the voyage preceding ours, those passengers had experienced only two hours of sunlight during their four days of landings.
We did get a third sunny day and in place of the canceled small-boat cruise of the 7-mile-long Lemaire Channel, everyone got a sightseeing trip in the craft among icebergs large and small. Much of our fourth and final day along the Antarctica Peninsula was overcast and gloomy, making the subfreezing temperature seem depressing, the continent that much more challenging.
A favorite image: a single gentoo penguin on a sizable but flat-topped icberg floating near the Fram. Although we had already viewed, photographed and videotaped thousands of the little critters in our previous landings, just one gentoo at sea was special.
When two boats stopped for photos, then left, this penguin had wandered in their direction and dived into the water. Was it trying to follow the boats? Not likely: Penguins are seabirds, meaning they come to land only to breed, so this one most likely had just been resting while looking for a meal.
What to wear today?
Layering clothes for the eight landings was a challenge.
Weather conditions changed rapidly, from landing to landing. Too many layers, combined with an uphill climb, could make your eyeglasses fog over and the layers closest to the skin get soaked with sweat from excess body heat. Too few layers and the strong wind could easily cut through the Teflon-coated nylon parka each passenger was given.
But Antarctica challenged us with more than icy conditions. On most of the landings, every step on the snow could mean sinking to your knee. This despite the fact that the expedition team of naturalists, geologists, ornithologists and biologists was dispatched to a landing site before the passengers, to mark safe places to walk.
Because Antarctica wildlife is rigorously protected, passengers were repeatedly told to keep at least 5 meters (almost 16 feet) away from the penguins and their "highways" — the narrow paths they created as they waddled between nest and sea to eat.
Penguins won't nest directly on snow, lest that cold prevent their eggs from hatching. Instead, the mature birds will climb steep hills to find bare rock on which to create their nests.
The construction materials are pebbles and small rocks the male carries, one at a time, in his beak. The guy with the coolest rock nest gets the girl. After she lays an egg, they take turns sitting on it, while the other penguin goes to the sea to feed.
The nesting penguin must guard the egg from the attacks of a chicken-sized bird named the skua. If they get the chance, skuas will peck at and break the egg, slurping up the contents. The penguins have no defense other than to stay atop the egg.
Once the chicks hatch, usually starting in January, the skuas will try to kill and chew on them — a scene the Fram passengers did not witness but which was clear in the BBC's Frozen Planet series, which was looping on our cabin TVs.
Something they don't mention in those wildlife documentaries is that cute as penguins are, their rookeries, or nesting colonies, stink. Nope, no other word for the smell.
The penguins' chief food is a tiny creature named krill. But penguins only partly digest the krill and then poop wherever they happen to be.
During breeding and chick-rearing times, the penguins spend most of their time in the rookeries. That ammonia/rotten-fish smell is another instance when Antarctica will take your breath away.
But deep snow to trudge, hills to climb, the stench — I even got dive-bombed by a skua being chased by another — are just annoyances compared to the excitement of being near the rookeries.
Embarrassed but honored
Originally, I didn't think our time ashore would be so rewarding. On the first landing, the 32 mph wind dropped the "feels like" temperature to minus 28, or 60 degrees below freezing.
On the days when the weather and landscape were most challenging, or when we plowed through 30-foot waves, I would feel embarrassed to step into either of the Fram's elevators.
In each was a 5-foot-tall headshot of one or the other of Norway's most famed polar explorers, Roald Amundsen and Fridtjof Nansen. Each had sailed on wooden ships named the Fram, Norwegian for "forward.''
In the photographs, the men looked out with weather-worn faces and hard eyes. I felt they were challenging me for daring to come to Antarctica in so much comfort.
Those men, and other European and American explorers of more than a century earlier, came in too-fragile sailing ships, wearing animal skins over woolen clothes, without my ship's redundant engines and satellite links, without at least three hot entrees at every meal, without hot showers.
Those explorers were more than just courageous and hearty souls — they were risking their lives. And many of them lost that gamble.
Thus finally, I felt privileged to have barely sampled what they had chosen to endure for months on Antarctica. Its magnificence does that to you.
