Investigating the controversial phenomenon
Found in abundance across Antarctica, the crabeater in fact feeds almost exclusively on krill.
Adelie penguins are the most southerly breeding penguin on earth, a distinction they share with Emperor penguins.
One of the smallest penguins in the Antarctic, they are named after the wife of 19th-century French explorer Jules Dumont d'Urville.
Did you know that the crabeater seal is the most abundant seal species in the world?
At sea, emperor penguins can dive up to 560 m—deeper than any other bird—and stay under water for up to 30 minutes.
The largest penguin species, they spend the long winter on the open ice and even breed during this harsh season. They also take turns looking after their young.
The second largest seal in the Antarctic, this species is solitary in its behavior, although they can become very vocal during the breeding season.
Looking very smug on its ice bed, a leopard seal takes a break between hunting trips. The species is a ferocious Antarctic predator, second only to the killer whale.
The gentoo is easily identified by its long tail, white stripe across the top of its head, and bright orange-red bill.
Impossibly cute with its big eyes and fixed smile, Weddell seals are excellent swimmers and can dive up to 600 m in search of prey.
A small bay in the larger Andvord Bay, Neko Harbor is flanked on one side by huge glaciers.
The landing at the harbor is referred to as a continental landing in that it's actually connected to the Antarctic Peninsula proper.
A solitary Antarctic minke whale surfaces briefly. Its blow is low and rarely seen.
Noisy and aggressive, chinstraps are named for the strap-like line that circles from each eye down under the chin.
One of the most rewarding destinations to see these penguins is Deception Island, where there is a colony of nearly one million.
Still active, Deception Island volcano wakes up from time to time, most recently having been in 1967 and 1969.
Port Lockroy, a natural harbor sited on Goudier Island, is the location of a former 1940s-era British scientific station, which is now a museum.
The Antarctic ice sheet is the biggest single mass of ice in the world.
Earth's southernmost continent, Antarctica is nearly twice the size of Australia.
Visitors are greeted by a display of original artifacts from the period, carefully preserved for posterity.
Believe it or not, Antarctica is classified as a desert—its annual precipitation is only 200 mm along the coast and even less inland.
Indeed, Antarctica's Dry Valleys are the most dismal places on earth. Here, the Onyx River, a meltwater stream, meanders across a valley floor through a landscape far removed from the brilliant white ice blanket more associated with the continent.

Deception Island, located in the South Shetland archipelago, forms part of an ancient caldera, a large volcanic crater.
A sleek profile makes the minke a fast swimmer. Its sickle-shaped dorsal fin helps identify the species.
Taylor Glacier in Victoria Land, East Antarctica is known for Blood Falls, a cascade of briny water high in iron, giving the unusual water feature a reddish tint.
The second-highest volcano in Antarctica, and the southernmost active volcano on Earth, Erebus features a lava lake of swirling magma and is truly a place where fire meets ice.
