15 interesting facts about Antarctica

A series of interesting facts about Antarctica that I uncovered during my research.

Earth’s southernmost continent held us in its thrall long before it was first sighted in January 1820, still just a blank space on the map.  The limitless solitude and silence, the vastness of scale, occupying mythical space in our imagination.  Even now, with the possibility to visit the continent as a tourist, we are drawn by the idea of blankness, the purity of a landscape without the cultural associations of our own, where we can make our own connections and add new pins to the map.

I’ve done a large amount of research recently to familiarise myself with Antarctica: the short human history and tales of exploration; ecosystems and wildlife; the rock and the ice; the striking natural beauty of the continent.  In the process, I’ve uncovered more than a few interesting facts on which to hang my own understanding and experience, and I’m sharing the best of them here.

Antarctica Facts

  • The Antarctic polar circle is an imaginary line circling the earth parallel to the equator at latitude 66°33′ S.  South of the line experiences at least one day of midnight sun at the December solstice, where the sun remains above the horizon, and at least one day of polar night at the June solstice, where the sun does not rise over the horizon.

  • Most of the landmass of Antarctica lies within the polar circle, with just the tip of the peninsula, Graham Land, and a few capes in Enderby Land and Wilkes Land extending north of the line.  However, all land and islands, and ice shelves, lying south of latitude 60°S are considered part of Antarctica, and governed by the Antarctic Treaty System (more on that below).
  • The true boundary of the Antarctic could also be considered the Antarctic convergence (AAC) zone, also known as the polar front, an oceanographic feature where the dense, cold waters of the Antarctic circumpolar current sink beneath warmer waters from the north.  The resulting upwelling of nutrients supports a rich diversity of marine life.  The convergence circles the continent at a latitude between 41°S and 61°S, in a band around 40km (25 miles) wide, and the variation is why island groups such as South Georgia (54°15′S 36°45′W) and Bouvetøya (54°25′S 3°22′E) are considered to be Antarctic in biogeographical terms, and Macquarie Island (54°38′S 158°50′E) and Cape Horn (55°58′S 67°17′W) are sub-Antarctic.

  • The name Antarctica was first formally used for the continent by Scottish cartographer John George Bartholemew in his work of 1890, after the term Terra Australis, which had described a speculative southern continent was used for the re-naming of New Holland (het Niew Hollandt) as Australia.  Antarctica is derived from the Greek antarktikós, the opposite of the Arctic, the opposite of north, used for unspecified and unknown southern lands since the days of AristotleArktos means bear, and arktikos referencing the northern constellations Ursa Major (Great Bear) and Ursa Minor (Little Bear).  The fact that polar bears live in the Arctic and not in the Antarctic is purely coincidental.
  • Antarctica is the coldest continent on Earth.  On 21st July 1983 a low of -89.2°C (-128.6°F, air temperature) was recorded at Vostock Research Station, on the isolated, inhospitable East Antarctic Plateau.  Recent satellite observations have suggested that it may get even colder in certain conditions, as low as -98°C.  The Antarctic peninsula, where most visitors will go, has a much milder climate, with January averages around 1 to 2 °C (34-36°F), though it can get as warm as 10°C (50°F).
  • The Antarctic has no indigenous population, and no permanent inhabitants.  Approximately 29 nations send personnel south of 60° to operate seasonal and year-round research stations, field bases, and research vessels, giving a summer population of around 5,000, dropping to just 1,000 or so over winter.  The number of summer residents are boosted by tourists, with more than 44,000 visitors recorded in 2016-17 season.
  • The Antarctic Treaty System is a unique set of international agreements, laying out the framework for governance of the region.  Originally signed in 1959, it establishes the peaceful pursuit of scientific research, international co-operation, and environmental protection as the goals for all nations active in Antarctica.

  • The first confirmed sightings of continental Antarctica happened just 200 years ago.  The Imperial Russian expedition led by Fabien Gottleib von Bellingshausen and Mikhail Lazarev, on the ships Vostok and Mirny, discovered an ice shelf on the Princess Martha Coast, on 27th January 1820, which later became known as the Fimbul Ice Shelf.  Just a few days later, on 30th January, Edward Bransfield, of the British Royal Navy, sighted the Trinity Peninsula, the northernmost tip of the Antarctic mainland.
  • An expedition led by Norwegian polar legend Roald Amundsen was first to reach the geographic South Pole on 14th December 1911.  Leaving the ship Fram, on loan from his fellow countryman Fridtjof Nansen, in the in the Bay of Whales at Framheim, he traversed the Axel Heiberg Glacier onto the polar plateau, using skis and sled dogs, reaching the pole in 56 days.  On realising their goal, the Norwegian team spent three days taking sextant readings, and “boxing the pole” to establish an exact position.  Despite setting out from their base at Cape Evans on Ross Island just five days later the Norwegians, it wasn’t until five weeks after Amundsen arrival that Robert Falcon Scott’s ill-fated team reached the pole.

  • Unlike in the Arctic, there are no large terrestrial animals in Antarctica.  In fact, the largest creature living on the land is a flightless midge, Belgica antarctica, just 6mm (0.25in) in length.  It’s reckoned that it’s flightlessness is an adaptation to prevent being swept away in the strong winds that blast the continent.
  • The richest and most diverse ecosystem in Antarctica is the ocean.  Nutrient rich water upwelling in the Antarctic convergence cultivates blooms of plankton, which feeds super-abundances of krill, small shrimp-like crustaceans.  In turn, the krill support many species of fish, seals, birds, and whales, including orcas, humpback whales, and blue whales, the largest of all.
  • Though we immediately think of penguins as the classic Antarctic bird, only a few species actually live that far south.  Of the 18 extant species worldwide, four can be considered Antarctic (Emperors, Adélies, Gentoos, and Chinstraps) and another four are sub-Antarctic (Kings, Royals, Southern Rockhoppers, and Macaronis).  If, like me, you can’t get enough of penguins, check out the BAS Penguin of the Day photos.

  • The famed Northern Lights, the aurora borealis, have a southern counterpart, the aurora australis.  The aurora is the result of disturbances in the upper atmosphere, when streams of charged particles ejected from the sun interact with the earth’s magnetic field.  The ideal time to observe the aurora australis in Antarctica is in the dark nights through the southern winter, however they can be seen from the Peninsula and South Georgia
  • The Antarctic Ice Sheet is the largest single mass of ice on earth, covering around 98% of the continent, an area equivalent to one and a half times the size of continental USA.  It’s estimated that it reaches as much as 4,700m (15, 420′ or 2.9 miles) thick at it’s greatest extent, and extends almost 2,500m (8200′ or 1.5 miles) below sea level in West Antarctica.  The extent of sea ice formed through the winter months almost doubles the size of the continent.  Unlike the Arctic, the area has remained fairly constant in recent decades, though the variation in ice thickness is unclear.

  • All is not well in Antarctica.  The rate of ice melt has doubled every decade since records were first kept, a direct consequence of increased air and water temperatures in the region.  The rate of air temperature rise (2°C or 3.2°F in the past 50 years) is one of the highest on the planet, resulting in a rise in sea levels and glacial ice calving faster than at any time since the records began.  Further increases in temperature will have profound effects on global weather patterns.

Armchair Travel: 10 Books to Explore Antarctica

at_antarctica

I’ve long had a fascination with Antarctica, being captivated by stories of exploration and discovery in Readers Digest books at my grandparent’s house on long Scottish summer afternoons.  Primary school trips to see the polar vessel RRS Discovery in Dundee, the three-masted barque that took Scott and Shackleton on their successful first voyage south, and to the penguin enclosure in Edinburgh Zoo, where I met Sir Nils Olav (then just RSM of the Norwegian King’s Guard), further fuelled that interest.

So I’ve been in an absolute whirlwind of excitement since finding out I’ve finally got the opportunity to go for myself; the realisation of a long-burning ambition.  I’m part of the team from the United Kingdom Antarctic Heritage Trust that will be based at Port Lockroy, to run the famous Penguin Post Office, for the 19/20 season.

In preparation, I immersed myself in Antarctic-themed reading, and these are some of my favourite books.  Until you get the chance for yourself, these books will transport you South.  I’ve also rated each book by the amount of penguin content it contains, not as a comment on the quality of the writing.  They’re all good books, Brent.

  • Antarctica: An Intimate Portrait of a Mysterious Continent – Gabrielle Walker

An excellent book covering everything you could possibly want to know about the “last great wilderness”, and the people drawn into its icy grasp for science, discovery and adventure.  Walker weaves together personal stories gleaned from her travels in Antarctica, from the heroic age of exploration through to current climate breakdown studies, from scientists in the distinctly earthbound fields of geology and ecology to cosmetologists looking into deep space and deep time.

Penguin rating: 🐧🐧 /5

  • Endurance: Shackleton’s Incredible Voyage – Alfred Lansing

Lansing is a powerful storyteller, and this is one of the most epic stories ever.  In 1914, the Endurance* set sail for Antarctica to establish a British base on the continent, and attempt the first overland crossing of the continent, but became trapped in the pack ice long before reaching her destination.  The shifting, thawing, and freezing ice splintered the vessel, stranding Shackleton and his crew on the floes.  The rest of the expedition is far more remarkable than the original plan, and against all odds, all survived.

Penguin rating: 🐧🐧/5

*a three-masted barquentine, which I know you needed to know.  Discovery, pictured above, is a barque.

  • The Worst Journey in the World – Apsley Cherry-Garrard

As the youngest member of the team accompanying Robert Falcon Scott on his ill-fated attempt to reach the South Pole, Cherry-Garrard was one of only three survivors of the expedition, and part of the rescue mission that discovered the frozen bodies of his colleagues. His account pieces together diary extracts from other team members, adding details of scientific endeavours and anecdotes of resilience and endurance in the frozen south, touched with survivor’s guilt.

Penguin rating: 🐧🐧🐧🐧🐧/5

Polar Exploration is at once the cleanest and most isolated way of having a bad time that has been devised.

  • Icebird – David Lewis

I’ve included book recommendations on sailing expeditions in the previously Armchair Travel series, but this one is, without doubt, about the greatest and most terrifying feat in singlehanded sailing; a solo circumnavigation of Antarctica in 1972.  Leaving Australia, Dr. Lewis sailed out of radio contact for three months.  On reaching Palmer Base on the Antarctic Peninsula, he revealed his 32′ (9.4m) steel cutter had capsized and dismasted twice (and would do so once more before the end of the expedition).  A phenomenal undertaking to read as a non-sailor, and your worst nightmare if you are a sailor.

Penguin rating: 🐧🐧/5

  • Alone in Antarctica – Felicity Aston

In 2012 Aston became the first person to complete a solo ski journey across the Antarctic land mass using muscle power alone**, taking 59 days to cover 1,744km (1,084 miles).  Having worked as a British Antarctic Survey meteorologist, Aston was familiar with the landscape and weather conditions she was to face, but not with the solitude and sensory deprivation in the vast white expanse of the polar plateau.

Penguin rating: 🐧/5

** Norwegian Børge Ousland made the first solo ski crossing in 1997, using a kite to assist his 3,000km (1,864 miles) journey, crossing from sea to sea.

  • The Last Viking: The Life of Road Amundsen – Stephen Brown

An excellent biography of Amundsen, the ultimate polar explorer, who in the UK is often sadly view as the villainous foil to Scott’s heroic failure.  The Norwegian expedition to the pole was meticulously planned, using indigenous knowledge gleaned from Amundsen’s time with Inuit in the Arctic, and relied on dog teams to haul sleds rather than mechanical transportation and manhauling.  In addition to winning the South Pole, he was the first to lead expeditions to traverse the Northwest and Northeast passages, and with Italian aeronaut Umberto Nobile, was first to reach the North Pole.

Penguin rating: 🐧🐧/5

  • End of the Earth: Voyaging to Antarctica – Peter Mattheissen

An account of his time spent guiding guests on Antarctic voyages across the Southern Ocean, carved out in sparkling, spare prose, at a serene, glacial pace through the geology and ecology of the continent.  His trademark austere writing style will not resonate with all readers, but the book is worth persisting with until it becomes all absorbing.

Penguin rating: 🐧🐧🐧🐧/5

  • The Library of Ice – Nancy Campbell

A journey into the beauty and power of the forces of nature, combining travel writing, memoir, science narrative, and literature, on a tour to observe the icy cold corners of the earth before they become irreparably diminished.  Beautifully and poetically written, with an artist’s eye, and an engrossing read as Campbell moves from curling rinks to cryo-labs to the crevasse that concealed Austrian iceman Ötzi.

Penguin rating: 🐧🐧/5

  • Empire Antarctica: Ice, Silence and Emperor Penguins – Gavin Francis

Francis was posted to the isolated Halley V research station as base doctor for a 14-month deployment, driven by a longing to see penguins since a childhood visit to Edinburgh Zoo, where my own fascination with Antarctica began.  A blend of personal memoir, polar history, and nature writing, meditating on the isolation and solitude of his experience.

Penguin rating: 🐧🐧🐧🐧🐧/5

  • Penguins Stopped Play – Harry Thompson

Yes, this is a book about cricket.  About a rubbish village cricket team with an epic losing streak at that.  But this hilariously funny and touchingly poignant account of an incompetent, disaster-filled attempt to play a match on every continent, including Antarctica, is the perfect companion book for tales of heroic expeditions, proving that passion and endurance in the face of tribulation isn’t just the reserve of adventurers.  Thompson is an excellent writer, and provides a handy chart of fielding positions, if like me silly mid off, cow corner, and third man mean nothing to you.

Armchair Travel: 10 Books about the North

Welcome to the first instalment of my Armchair Travel series!

In this occasional series I’ll aim to bring you inspiration for your travels, and transport you away from everyday life, through some of my favourite books. Like a wee holiday, but without leaving the comforts of your home.

For me, reading has always provided so many of the things I get from travelling: being exposed to new ideas and ways of thinking; an insight into an unfamiliar culture; being part of a challenging adventure; or complete and total escapism.

Books, like a sailing ship, could take you anywhere. So throw off the bowline and let yourself be transported with ten of my favourite books to take you in to the icy north…

  • Arctic Dreams – Barry Lopez

I love books like this, ones that outwardly take a single topic, but are packed with everything you can think of. History, geography, science, natural history, spirituality, indigenous culture, adventure, travel; all drawn together in Lopez’ beautiful prose. To be dipped into again and again.

  • North Star of Herschel Island: The Last Canadian Arctic Fur Trading Ship – R. Bruce Macdonald

Sailing ships might become a bit of a theme through this blog. This is the story of the last of the ships trading in the Canadian Arctic, and a record of a way of life changed forever.

  • Dark Matter – Michelle Paver

A chilling horror story set in a scientific research base in an abandoned mining camp in Spitzbergen, just before the outbreak of WWII. The waning of the moon in the depth of the polar night plunge Jack into full-blown terror.

  • Far North and Other Dark Tales – Sara Maitland

A deliciously dark collection of short stories that draw inspiration from fairy tales, bible stories and traditional myths, with a strong focus on the female experience. The title story is a reworking of an Inuit legend.

  • The Last Viking: The Life of Roald Amundsen – Stephen R. Brown

We tend to know Amundsen as “the one that got there first”, thwarting Scott’s attempt at the South Pole, but the Norwegian was the ultimate polar explorer. Inspired by Nansen and learning skills from indigenous peoples in the Arctic, he was leader of the first voyage to traverse the Northwest Passage, navigated a route through the Northeast Passage, and crossed the North Pole in an airship. He disappeared on a mission to rescue the crew of another airship returning from the Pole.

  • The Long Exile – Melanie McGrath

The documentary film Nanook of the North revealed the lives of Unagava Inuit to the world. This book reveals the dark aftermath; the forced relocation of Inuit families to the barren shores of Ellesmere Island. A shameful episode of recent history, the shockwaves of which echo through the generations to today.reading_for_a_cold_day_1

  • The Northern Lights – Philip Pullman

The first part of the Dark Materials trilogy (also known as The Golden Compass in North America), this is the north of dreams and fantasy. Ice bears in armour made from sky-iron; lying, tale-telling Arctic foxes; ancient witches flying of sprays of cloud pine; fierce Tartars scouring the tundra with their wolf dæmons; and the mysterious and terrible aurora.

  • To Build A Fire – Jack London

I read White Fang when I was about twelve years old, and Call of the Wild not long after. The wild and brutal Yukon setting burned into my imagination. To Build a Fire is just one of the greatest short stories ever written.

  • Farthest North – Fritjof Nansen

I have a massive crush on Nansen; there’s no denying it. I’m fascinated by so much about him; all his adventures, his thirst for scientific knowledge, and his humanitarian work. This is the story of the Fram expedition, to take a ship through the polar sea locked in the ice, and reach the top of the world. And on the way, demonstrate excellent leadership and establish the science of oceanography.

  • The Blue Fox – Sjón

Fabulous, in the original sense of the word, and beautifully poetic, the atmosphere of this novella is as dark and chilling as the Icelandic winter in which it is set. It may not be everyone’s cup of tea, but it will transport you to a different world.
