Deception Island deceptively active

In Antarctica, the South Shetland archipelago is home to Deception Island, a volcanic-rounded island that is 15 km in diameter with a shield volcano. The volcano is mainly basalt-andesite and was one of the first parts of Antarctica to be discovered, probably around 1820 by UK and USA sealers.

How Arctic Wildlife Differs from Antarctic

While the north and south poles share certain characteristics, they are also remarkably distinct. Both regions are cold and dry, yet each has its own unique terrain and climate. The Antarctic is particularly harsh and inhospitable, with only two native vascular plant species, whereas the Arctic tundra supports a wider range of fauna due to its relatively warmer temperatures and greater plant diversity. Here are some of the animals you can find in the Arctic compared to the Antarctic.

10 Bountiful Blue Whale Facts

The umbrella term “whale” refers to a wide variety of large marine mammals. To zero in on blue whales, however, we’ll need to unpack this term a bit. The Latin word for whale, cetus, is the root of the whale infraorder, Cetacea, the largest parvorder of which is Mysticeti.

Living the Antarctic Dream

From October to March, during the Austral summer, thousands of breeding gentoo, Adèlie, and chinstrap penguins flock to the Western Antarctic Peninsula to rear their chicks and feast on krill before the harsh winter arrives. Alongside the penguins, field biologists from around the world gather to study these habits for conservation research. Observing these animals is one thing, but residing in an Antarctic field station for an entire breeding season is another. One particular field camp on King George Island, managed by American scientists, has perfected this Antarctic lifestyle and has thrived for over 30 years.

10 Traits of Post-Ice-Age Greenland

Grasses, sedges, and other species of heath were the first arrivals, and are still commonly found in Greenland. Scientists have been able to work out how plants colonised Greenland by examining ancient pollen samples found in deposits at the bottom of lakes: Dwarf birch came to western Greenland around 9,000 years ago, and around 4,500 years ago – roughly the same time humans were first boating onto Greenland shores – green alders were taking up residence there.
