A journey back in time to the frozen south

The vast, frozen wilderness at the southernmost tip of our planet has long captured the imagination of explorers, scientists, and adventurers alike. Isolated by ferocious seas and shrouded in mystery for centuries, the White Continent has always been the final frontier of terrestrial discovery. 

From early theories of a vast southern land to the legendary South Pole expedition races, the history of Antarctic exploration is a testament to human endurance, ambition, and sheer determination. This article traces the key moments of Antarctic expeditions–from the first sightings and 19th-century voyages to the Heroic Age of Amundsen and Shackleton, and the modern era of international scientific research.

Who discovered Antarctica?

For centuries, cartographers and philosophers speculated about the existence of Terra Australis Incognita – an unknown southern land. However, it wasn’t until the early 19th century that the world finally set eyes on Antarctica. The honour of discovery is often attributed to multiple explorers who, in rapid succession, encountered the continent’s forbidding coastline.

Captain James Cook

Cook's second voyage (1772–1775) on HMS Resolution and HMS Adventure was a major European effort to explore the Southern Ocean. Tasked with locating the mythical Terra Australis, Cook ventured further south than any navigator of his era, crossing the Antarctic Circle at 66° 33' in 1773. During some of our Secret Atlas Expedition Micro Cruises to Antarctica, you will be able to cross this latitudinal line, a demarcation on the map indicating that you are definitively in the southernmost realms of our planet. All the lands between the Antarctic Circle and the South Pole are called Antarctica. 

Captain William Smith

In the annals of discovery, there is a distinction between sighting an Antarctic island, landing on an island near Antarctica, and setting foot on the continent. The first recorded landing on an island near Antarctica occurred in 1819 when British sealer Captain William Smith (from aboard the two-masted Brig Williams) first set foot on King George Island in the South Shetland Islands. His discovery and reports of plentiful fur seals helped pave the way for further exploration of the region. The Williams played a key role in early Antarctic exploration and was used to chart the waters around the Antarctic Peninsula.

In 1820, three expeditions sighted Antarctica almost simultaneously: Russian explorers Fabian Gottlieb von Bellingshausen and Mikhail Lazarev aboard the Vostok and Mirny, British naval officer Edward Bransfield aboard Williams, and American sealer Nathaniel Palmer aboard Hero. Though they glimpsed the icebound continent, they did not set foot upon it.

While Palmer actively explored the South Shetland Islands, there is no verified evidence that he landed on the Antarctic mainland. That feat was not accomplished until 1895 when a Norwegian team, led by Henrik Johan Bull aboard Antarctic, first landed on the Antarctic Peninsula.

Early expeditions and the mapping of Antarctica

Following its discovery, the 19th century saw a wave of early Antarctic expeditions, driven by scientific curiosity, the lucrative sealing industry and a hunger for polar discovery. The British, French, and American missions of the 1830s and 1840s mapped large sections of the coast.

James Clark Ross

Among the most significant was James Clark Ross’s voyage (1839–1843), during which he discovered the Ross Sea and the towering Ross Ice Shelf. This area, opposite the Antarctic Peninsula, later became a key starting point for South Pole expeditions. Ross, a British naval officer, played a crucial role in Antarctic exploration, leading the Ross Expedition aboard HMS Erebus and HMS Terror. He also identified the towering volcanoes Mount Erebus and Mount Terror, aptly named after his ships. 

On our expeditions, we sail through the same waters and may view Mt Erebus from a distance. Dive deeper into this landmark with our dedicated article on Mt Erebus.

Ross’s work laid the foundation for future Antarctic expeditions, and his precise magnetic surveys helped refine the understanding of Earth’s magnetic field. Despite his achievements, he remains somewhat overshadowed by the later, more dramatic expeditions of the Heroic Age.

The Heroic Age of Antarctic exploration: Amundsen, Scott, and Shackleton

The late 19th and early 20th centuries were crucial in Antarctic history, characterised by daring expeditions, immense challenges, and lasting legacies of explorers who aimed to conquer the frozen continent.

The race to the South Pole: Amundsen vs. Scott

The South Pole expedition of 1911 remains one of the most dramatic chapters in polar history. Norwegian explorer Roald Amundsen, originally planning an Arctic voyage, unexpectedly pivoted southward aboard the famous ship Fram (meaning "forward" in Norwegian) upon learning of Robert Falcon Scott’s British Antarctic expedition.

Amundsen’s decision to race Scott in the most iconic South Pole expedition in history was driven by ambition, rivalry, and a deep need to prove himself in the world of Antarctic explorers.

Utilising skis and sled dogs – giving his team a significant advantage over Scott’s party – Amundsen reached the South Pole on December 14, 1911. His team planted the Norwegian flag and spent several days taking measurements to ensure the accuracy of their records before departing on December 17, 1911. His superior strategy, including careful route planning, expert use of dogs, and reliance on ski travel, ensured both his success and his team’s safe return.

Scott’s team, in contrast, faced insurmountable challenges using a combination of man-hauling, ponies, and motor sledges. They arrived at the South Pole on January 17, 1912, only to find Amundsen’s flag already planted. Tragedy struck on their return journey, with all five members perishing in the brutal Antarctic conditions. Scott’s expedition became a poignant symbol of endurance and sacrifice, while Amundsen’s victory cemented his legacy as one of history’s greatest Antarctic explorers.

Shackleton’s legendary Endurance expedition

If Scott’s journey was one of tragedy, Ernest Shackleton’s Trans-Antarctic Expedition began and took a strange turn from aboard  Endurance (1914–1917). What began as a continental crossing quickly and unexpectedly shifted into a tale of extraordinary survival. Shackleton is remembered for his unwavering courage and leadership, making him one of the most revered figures in Antarctic exploration.

Attempting the first Trans-Antarctic crossing, Shackleton’s ship, Endurance, became trapped in pack ice and was eventually crushed. Stranded on the ice for months, Shackleton and his crew navigated lifeboats across the perilous Weddell Sea to Elephant Island. In an audacious move, Shackleton and five men then embarked on an 800-mile journey in an open boat to South Georgia, securing rescue for his entire crew, whom he later returned to save.

Though Shackleton’s Endurance expedition never crossed the continent, it became one of the greatest survival stories in the history of Antarctic exploration.

The definitive book on Shackleton’s saga is Endurance: Shackleton’s Incredible Voyage by Alfred Lansing. If you want to hear it straight from The Boss himself, read South by Ernest Shackleton. Also, check out The Ship Beneath the Ice: The Discovery of Shackleton’s Endurance by Mensun Bound for a modern perspective on his legendary journey.

On our expeditions, you can stand where Shackleton stood and even hike the same route he took across South Georgia (weather permitting!). 

The end of a great era

The Heroic Age of Antarctic Exploration is generally considered to have ended in 1917, following the conclusion of Shackleton’s ill-fated trans-Antarctic expedition. This era was defined by daring, often tragic, attempts to explore and conquer the poles, with explorers like Amundsen, Scott, and Shackleton making legendary contributions to the understanding of the polar regions.

Marked by immense challenges, rudimentary equipment, and unpredictable conditions, the Heroic Age was a time of extraordinary risk, sacrifice, and discovery.

Modern Antarctic exploration: from science to satellites

Following the Heroic Age, the next major phase of Antarctic exploration is commonly referred to as the Scientific Age of Polar Exploration or Modern Polar Exploration. Beginning in the late 1910s and transitioning into the 1930s, this era focused on systematic, scientific study rather than personal achievement.

While the earlier age centred on conquest and exploration, the Scientific Age emphasised international collaboration, technological advancements, and environmental research.

The early 20th century saw rapid advancements in technology that transformed Antarctic exploration. One of the most significant breakthroughs was the use of aviation, pioneered by American explorer Richard Byrd. Between 1928 and 1935, Byrd led multiple expeditions, achieving the historic first flight over the South Pole in 1929. His aerial surveys revolutionised mapping efforts and laid the foundation for modern scientific research on the continent. Aeroplanes, helicopters, submersibles – and later, satellites – became essential tools for studying Antarctica’s vast, ice-covered terrain and surrounding oceans.

The first women in Antarctica (1930s–1940s)

Early Antarctic exploration was dominated by men, but the 1930s and 1940s marked the beginning of women’s presence on the continent. In 1935, Norwegian explorer Caroline Mikkelsen became the first woman to set foot on Antarctica, albeit briefly. Over a decade later, Jackie Ronne and Jennie Darlington became the first women to overwinter, proving that polar exploration was no longer solely a male domain. Their involvement paved the way for future generations of female scientists, researchers, and adventurers who continue to make significant contributions in Antarctica today.

The Antarctic Treaty: preserving the frozen continent

In 1959, the Antarctic Treaty was signed by 12 nations, including the United States, the Soviet Union, and the United Kingdom, establishing Antarctica as a region dedicated to peaceful, scientific cooperation. The treaty, which came into effect in 1961, prohibits military activity, mineral mining, and territorial claims while promoting environmental protection and international research. Over time, the agreement has expanded to include more than 50 countries, ensuring that Antarctica remains a global sanctuary for science and conservation.
