Ross Ice Shelf Antarctica

When James Clark Ross sailed south into the ice in January 1841, he expected to reach the open polar sea that cartographers of the era assumed must exist at high southern latitudes. Instead, on 28 January, he encountered something no one had prepared him for: a wall of ice stretching across the entire horizon, rising fifty to sixty metres above the water, absolutely vertical, running for hundreds of kilometres without a break or an inlet. He called it “the Barrier.” His ships, HMS Erebus and HMS Terror, could go no further south. No sailing vessel would pass it for another sixty years.

The Ross Ice Shelf, as it has been known since 1953, covers approximately 487,000 square kilometres, roughly the size of France. It is the largest ice mass of its kind on earth. The shelf is several hundred metres thick, with about ninety percent below the waterline. The vertical ice face at the northern edge, called the Ross Ice Front, stretches roughly 800 kilometres between Ross Island to the west and the Edward VII Peninsula to the east. Tabular icebergs the size of small countries calve from this front; iceberg B-15, which broke free in 2000, was about 295 kilometres long and 37 kilometres wide, larger than Jamaica.

Who Actually Gets to Go

The Ross Ice Shelf is not a tourist destination in any conventional sense. McMurdo Station, the American research facility on Ross Island, and Scott Base, the New Zealand station nearby, are not open to tourists. Access to both is through government-run national Antarctic programmes and requires a formal invitation or scientific role.

The one practical way for a civilian to see the Ross Ice Shelf is by expedition cruise ship. A handful of operators run voyages into the Ross Sea each year, but the window is extremely narrow: sea ice makes the Ross Sea navigable only in January and February. Departure ports are Bluff or Lyttelton in New Zealand’s South Island, or occasionally Hobart in Tasmania. The passage south from New Zealand takes about six days each way, making these roughly 30-day voyages in total. Operators including Heritage Expeditions, Aurora Expeditions, and Scenic Eclipse run regular sailings during this window; a typical berth costs between USD 15,000 and USD 50,000 per person depending on the operator, ship, and cabin category. These are not budget options by any definition, and the voyages sell out months or years in advance.

The payoff is extraordinary access. The Ross Sea is one of the least visited and most intact marine ecosystems on earth. The itinerary typically includes Cape Adare, which holds the largest Adelie penguin colony in Antarctica, and the historic huts of Scott and Shackleton’s expeditions on Ross Island, preserved in near-perfect condition by the cold dry air. The ice shelf itself, viewed from a zodiac or from the ship’s deck, is the moment most passengers describe as the centrepiece: that flat, blinding white wall running to both horizons, absolutely still, absolutely silent except for the occasional thunderclap of calving ice.

The Scott and Shackleton Huts

Two of the three historic huts on Ross Island are accessible by zodiac landing and are managed by the Antarctic Heritage Trust. Discovery Hut, built by Scott’s 1901-04 expedition, and the Cape Evans hut used by Scott’s 1910-13 expedition, are the main ones visited. The interiors are preserved with expedition equipment, food tins, and personal effects still in place more than a century later. The Cape Evans hut, from which Scott’s ill-fated polar party departed in late 1911, is the more complete. Standing inside it while the same kind of ice landscape Scott looked out at is visible through the window is one of the genuinely affecting experiences in travel.

The Terra Nova Expedition left from Cape Evans in November 1911. Scott’s party reached the South Pole on 17 January 1912, thirty-three days after Roald Amundsen’s Norwegian team had beaten them to it. All five members of Scott’s polar party died on the return journey. Their bodies and final diary entries were found by a search party in November 1912, about 18 kilometres from a depot that could have saved them.

Wildlife

The Ross Sea supports large populations of Weddell seals, which haul out on sea ice close to shore and are exceptionally unbothered by human presence due to minimal predator pressure. Minke whales and killer whales frequent the shelf edge. Adelie and emperor penguins are both present; the emperor colonies are typically reached only by Hagglund oversnow vehicle from McMurdo in a research context, but Adelies are visible at Cape Adare and other landing sites. The bird life includes Antarctic petrels and snow petrels, both of which breed nowhere else on earth.

Practical Considerations

For expedition cruise passengers, the ship provides accommodation, meals, and all landing equipment. Zodiac skills are not required but the ability to step in and out of a small inflatable boat from a moving ship’s deck is necessary. All passengers are briefed thoroughly. The Antarctic Treaty System requires expedition vessels to comply with biosecurity protocols: boots must be cleaned between ship and shore, and there are strict limits on the number of passengers ashore at any one time, typically 100 passengers maximum for larger ships.

Cold-weather layering works on the principle of wicking, insulating, and windproofing. Most operators provide a list of recommended kit; waterproof over-trousers and expedition-weight mid-layer are the most commonly underpacked items. Temperatures during January and February on the ice shelf range from around -5 to +5 degrees Celsius at the surface, but wind chill and the albedo effect from the surrounding white ice make it feel considerably colder.

If your objective is the Ross Ice Shelf specifically rather than the Antarctic Peninsula, which is a separate and more accessible destination reachable from Ushuaia in Argentina on shorter 10 to 14-day voyages, plan two to three years ahead. The Ross Sea sailings are few, the ships are small, and demand from the small but dedicated community of serious polar travellers outstrips supply consistently.
