The Weddell Sea & Larsen Ice Shelf

At 55 degrees latitude south, Ushuaia (pronounced oo-swy-ah) is closer to the South Pole than to Argentina's northern border with Bolivia. It is the capital and tourism base for Tierra del Fuego, the island at the southernmost tip of Argentina.Although its stark physical beauty is striking, Tierra del Fuego's historical allure is based more on its mythical past than on rugged reality. The island was inhabited for 6,000 years by Yámana, Haush, Selk'nam, and Alakaluf Indians. But in 1902 Argentina, eager to populate Patagonia to bolster its territorial claims, moved to initiate an Ushuaian penal colony, establishing the permanent settlement of its most southern territories and, by implication, everything in between.When the prison closed in 1947, Ushuaia had a population of about 3,000, made up mainly of former inmates and prison staff. Today the Indians of Darwin's "missing link" theory are long gone—wiped out by diseases brought by settlers and by indifference to their plight—and the 60,000 residents of Ushuaia are hitching their star to tourism.The city rightly (if perhaps too loudly) promotes itself as the southernmost city in the world (Puerto Williams, a few miles south on the Chilean side of the Beagle Channel, is a small town). You can make your way to the tourism office to get your clichéd, but oh-so-necessary, "Southernmost City in the World" passport stamp. Ushuaia feels like a frontier boomtown, at heart still a rugged, weather-beaten fishing village, but exhibiting the frayed edges of a city that quadrupled in size in the '70s and '80s and just keeps growing. Unpaved portions of Ruta 3, the last stretch of the Pan-American Highway, which connects Alaska to Tierra del Fuego, are finally being paved. The summer months (December through March) draw more than 120,000 visitors, and dozens of cruise ships. The city is trying to extend those visits with events like March's Marathon at the End of the World and by increasing the gamut of winter activities buoyed by the excellent snow conditions.A terrific trail winds through the town up to the Martial Glacier, where a ski lift can help cut down a steep kilometer of your journey. The chaotic and contradictory urban landscape includes a handful of luxury hotels amid the concrete of public housing projects. Scores of "sled houses" (wooden shacks) sit precariously on upright piers, ready for speedy displacement to a different site. But there are also many small, picturesque homes with tiny, carefully tended gardens. Many of the newer homes are built in a Swiss-chalet style, reinforcing the idea that this is a town into which tourism has breathed new life. At the same time, the weather-worn pastel colors that dominate the town's landscape remind you that Ushuaia was once just a tiny fishing village, snuggled at the end of the Earth.As you stand on the banks of the Canal Beagle (Beagle Channel) near Ushuaia, the spirit of the farthest corner of the world takes hold. What stands out is the light: at sundown the landscape is cast in a subdued, sensual tone; everything feels closer, softer, and more human in dimension despite the vastness of the setting. The snowcapped mountains reflect the setting sun back onto a stream rolling into the channel, as nearby peaks echo their image—on a windless day—in the still waters.Above the city rise the last mountains of the Andean Cordillera, and just south and west of Ushuaia they finally vanish into the often-stormy sea. Snow whitens the peaks well into summer. Nature is the principal attraction here, with trekking, fishing, horseback riding, wildlife spotting, and sailing among the most rewarding activities, especially in the Parque Nacional Tierra del Fuego (Tierra del Fuego National Park).

Use your days spent in the Drake Passage to familiarise yourself with your ship and deepen your knowledge of the Antarctic. The Expedition Leader will first present the IAATO rules of conduct that must be observed during landings in the region and will explain everything you need to know about the zodiac outings. Lectures about the history and wildlife of the Antarctic will be an opportunity for you to learn more about this magical region, where every cruise is a unique experience. You will experience exceptional sailing moments on board and join the naturalist-guides on your ship’s exterior decks to look out for albatrosses, cape petrels, and other seabirds flying over the Drake Passage.

Remote and otherworldly, Antarctic is irresistible for its spectacular iceberg sculptures and calving glaciers, and for the possibility of up-close encounters with marine mammals and the iconic penguins. The Antarctic Peninsula – the main peninsula closest to South America – has a human history of almost 200 years, with explorers, sealers, whalers, and scientists who have come to work, and eventually intrepid visitors coming to enjoy this pristine and remote wilderness. It is a region of protected bays, unscaled snow-capped mountains, vast glaciers and a few places where whalers or scientists have worked. Just as irresistible are the many Gentoo and Chinstrap Penguin colonies, the seals basking on ice floes, the whales and orcas.

As you explore the Weddell Sea, you will sail towards the gigantic Larsen Ice Shelf. The beauty of this immense ice formation is fascinating; nonetheless, its monumental size must not make us forget the fragility of its existence. These floating platforms are what protect the continental ice cap – also called the inlandsis – from erosion and are thus of paramount importance for the entire balance of our planet. As you get up close to this equally majestic and vertiginous spectacle, you will really understand the need to protect these ice shelves. Our team of passionate experts will share their knowledge of these ice shelves that create gigantic tabular icebergs – among the largest ever observed - that drift in the Southern Ocean.

Impassable, extreme and captivating: this is the best way to describe the Weddell Sea, much of which is covered by a layer of thick, densely packed ice. It is a challenge and a privilege to sail upon this sea. Polar exploration finds its full meaning here. Heading towards the South is a real quest, with the promise of highly-charged encounters with the continent’s endemic fauna. This is the kingdom of the emperor penguin, the largest penguin in the world, renowned for its elegance. Unlike other penguins that live on the rocks, the emperor nests on the ice floe which it needs for its reproductive cycle. It is therefore on the ice floe that you will be able to observe it walking around with its characteristic gait. In this southern sea, where the ice changes and is transformed constantly, there is never any monotony. The new reliefs and new colours ensure never-ending wonderment. You will sail into the heart of the immaculate ice floe, which is dislocated or densely packed, into an alley of icebergs. Among them are immense blocks of ice, tabular icebergs, that drift and illuminate the ocean with their cerulean blue haloes. Aboard, on shore, on the ice, you will be as close as possible to the colonies of Adelie penguins, Weddell seals, Mink whales, orcas, snow petrels.… With a little luck, you will get a glimpse of a rare Ross seal with its silver pelage or of emperor penguins, waddling along the edge of the ice floe. A sight that is as fascinating as it is emotional.

Throughout your time in the north of the Antarctic Peninsula, you will find yourself in the heart of a spectacular decor in subtle shades of blue and white, surrounded by exceptional wildlife. You will sail through the Antarctic Sound, named after Swedish explorer Otto Nordenskjöld’s ship, which was trapped by the ice during an important scientific expedition in 1902. The gateway to the Weddell Sea, this sound is filled with gigantic tabular icebergs and plates of sea ice drifting northward from the coastal areas of this vast sea. It is home to Adelie penguins and a great many leopard seals.
