Why Join a Weddell Sea Expedition Cruise?​

The Weddell Sea region is renowned for vast amounts of ice – sea ice, pack ice and huge icebergs that are formed by huge floating sheets of thick ice that border the Weddell Sea. Even icebreakers have difficulty getting deep into the Weddell Sea due to at-times severe ice conditions. However, our purpose-built ships were built for these conditions, and our Weddell Sea cruises Expedition Teams are skilled at navigating you past the ice shelves. For adventurous expeditioners, a visit to the area is incredibly rewarding, not least for its historical associations.

In 1902, explorer Otto Nordenskjöld and his Swedish Antarctic expedition was forced to spend two winters in the Weddell Sea, and the main expedition hut built on Snow Hill Island still stands. The area is also central to Ernest Shackleton’s story. It was in the Weddell Sea that Shackleton’s Ship the Endurance was abandoned by Shackleton and his crew, after it became trapped in the ice. In addition to marvelling at ice-scapes, the area is rich in geology and palaeontology. 

A considerable aspect of a voyage to the Weddell Sea is the thrill of not knowing if the ice will allow us to enter its frozen realm. The Weddell Gyre pushes enormous amounts of ice from the Filchner-Ronne Ice Shelf up towards the area near Antarctic Sound, sometimes blocking the entrance to the Weddell Sea. If you are fortunate enough to access this unique Antarctic region, a visit to  has numerous rewards.  

The Weddell Sea is a region of the Southern Ocean that is known for its unique and pristine waters. The sea is characterised by extremely low levels of pollutants, high levels of dissolved oxygen and extremely cold temperatures, with the surface water often hovering just above freezing. This cold water is able to hold a significant amount of dissolved oxygen, which supports a diverse and thriving ecosystem of marine life. The Weddell Sea is home to diverse wildlife, including Antarctic krill, emperor penguins and Weddell seals. The sea is also an important breeding ground for many species of seabirds, which rely on the rich waters to support their young. Despite its remote and harsh weather conditions, the Weddell Sea is a vital part of the global ocean ecosystem, playing a key role in regulating the Earth’s climate and supporting life both in the sea and on land.

Weddell Sea Wildlife Encounters​

The abundant ice attracts seals such as crabeater, leopard and Weddell seals, which all breed and birth on the thick layer of sea ice. On Weddell Sea cruises, keep a look out for orca, humpback and minke whales who inhabit the region. While ashore, you can scour for ancient fossils of gastropods, large clams and spiral-shaped ammonites.   

The Weddell Sea boasts a large Adélie penguin colony just outside of the Antarctic Sound, some of which breed on the rocky slopes of a small volcanic island, where a large colony of Antarctic blue-eyed shags jostle for space with nest-building Wilson’s storm petrels.  

While Snow Island is the northernmost breeding colony of the Emperor Penguin, the chances of seeing them in the Weddell Sea are slim. Sadly, they are under threat due to disturbances to food supply and habitat. 

Unique Weddell Sea Experiences

Central to the story of where Sir Ernest Shackleton’s ship, the Endurance became trapped in formidable sea ice, the Weddell Sea certainly is high on the list for many polar adventurers. Your knowledgeable Expedition Team will bring their stories to life through lectures and guided commentary as we explore the region.

A group of small islands, including Joinville Island, Dundee Island, and Snow Hill Island, stand off to the east of the Antarctic Peninsula, collectively forming the Antarctic Sound. This remote and beautiful area is considered the gateway to the Weddell Sea, one of the most pristine and unspoiled regions of Antarctica. With a well-deserved reputation as being an iceberg alley, many large tabular bergs escape the Weddell Sea through the Antarctic Sound, often making navigation difficult but the ultimate adventure, and incredibly rewarding if you are successful.  

Join a Zodiac cruise as we move safety between gigantic icebergs, and land on remote beaches where ancient fossils can be found. Watch your step and keep a safe distance as fur seals and Weddell seals sleep peacefully on the beaches.

Svalbard Tours Regions

The Svalbard archipelago has nine main islands; some of these islands are connected by sea ice and expedition cruises are the only safe way to move between them. A lot of these islands are national parks, in fact, Svalbard has seven national parks in total. Find out more about the main islands below.


Svalbard’s largest island is 39,044 square kilometres. Its landscape is dominated by rugged mountains indented by post-card perfect fjords, and more than half of the island is covered in ice year-round. Six national parks protect its delicate environment and diverse fauna, which makes it a favourite for travellers visiting Svalbard. Spitsbergen is the only permanently inhabited part of Svalbard, with Longyearbyen the biggest settlement and administrative centre of Svalbard.

Nordaustlandet (North East Land)

The second largest island in the Svalbard archipelago is completely uninhabited. Situated entirely within the Nordaust-Svalbard Nature Reserve, it is made up of sizable ice caps and tundra.

Edgeøya (Edge Island)

Edgeøya is a Norwegian island situated in the southeast of the Svalbard archipelago. With an area of 5,073 square kilometres, it is the third-largest island in this archipelago. It forms part of the Søraust-Svalbard Nature Reserve and is home to polar bears and reindeer.

Kittiwakes on sea ice in the Arctic

Barentsøya (Barents Island)

Named after the Dutch explorer Willem Barentsz, almost half of this island in the Søraust-Svalbard Nature Reserve is glaciated. While the island has no permanent human inhabitants, it is a favourite of polar bears and seabirds, especially kittiwakes.

Prins Karls Foreland (Prince Charles Foreland)

This long island on Svalbard’s west coast and its surrounding seas constitutes Forlandet National Park. It boasts jagged peaks and wild glaciers that remind one of the Antarctic peninsula, alongside vast green plains and polar deserts. The harbour seal is commonly found here.

Kvitøya (White Island)

When ice conditions allow, adventure seekers can discover Svalbard’s easternmost island, where polar bears roam and walrus swim. This island is the resting place of Andrée’s Arctic balloon expedition of 1897, which was one of the great mysteries of the Arctic for decades.

Kong Karls Land (King Charles Land)

This small island group is part of the Nordaust-Svalbard Nature Reserve and boasts the largest concentration of polar bears in Svalbard. Because of this, there is a ban on traffic to the island, with ships and aircraft not being able to come within 500 metres of the area.

Bjørnøya (Bear Island)

The southernmost island of Svalbard is rarely visited because it can be challenging to access, with no protected bays, rough weather, strong wind and thick fog. While its history revolves around hunting, it is now an important scientific research site and the whole island is a nature reserve with restricted access.

A lone Black Guillemot resting on sea ice in the Arctic


This small, remote island in the far southeast is part of the Southeast Svalbard Nature Reserve. Visiting can be a lucky dip because of heavy ice, fog, rough waters and unprotected beaches. The island has been identified as an Important Bird Area (IBA), supporting breeding colonies of thick-billed guillemots, black guillemots and black-legged kittiwakes.
