Latest Antarctica Stories
Norwegian explorer Roald Amundsen might have been the first person to reach the South Pole, but an international team of scientists has discovered that he was actually beaten to his destination – by industrial air pollution.
Genetic analysis of Antarctic fur seals, alongside decades of in-depth monitoring,* has provided unique insights into the effect of climate change on a population of top-predators.
Much of the climate change-related research published recently has focused on the impact of warming temperatures on the West Antarctic ice sheet – but what is it about this region that causes scientists to be so interested in it?
The near-threatened Adélie penguin population has started to recover, as scientists conducting the first-ever global census of the creatures claim that the number of breeding pairs is over 50 percent higher than previously believed.
A long-term study of the links between climate and marine life along the rapidly warming West Antarctic Peninsula reveals how changes in physical factors such as wind speed and sea-ice cover send ripples up the food chain, with impacts on everything from single-celled algae to penguins.
New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated.
A team of scientists from Reno, Nevada’s Desert Research Institute (DRI) led by Michael Sigl and Joe McConnell have reconstructed historic volcanic sulfate emissions from the Southern Hemisphere.
In less than 100 years, global warming’s impact on the sea ice where emperor penguins breed will result in the loss of at least one-fifth of the species’ population, according to new research appearing in the June 29 edition of the journal Nature Climate Change.
Field surveys and satellites complement each other when studying remote penguin populations
Emperor penguins have a reputation for faithfully returning to the same nesting locations every year but a new study from researchers at the University of Minnesota has found that the reality may not fit this reputation.
Mount Erebus is an active volcano that can be found on Ross Island in Antarctica. It is the second largest volcano in Antarctica, reaching a height of 12,448 feet. Sir James Clark Ross discovered it in 1841 in mid-eruption and named it and another volcano Mount Erebus and Mount Terror, after two of his ships. The first people to climb the volcano and reach its summit were part of Sir Ernest Shackleton's party, including Professor Edgeworth David, Jameson Adams, and Dr. Eric Marshall. Mount...
Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...
The Ross seal (Ommatophoca rossii) is a true seal in the Phocidae family, and can only be found on pack ice in Antarctica. This species was formally described by James Clark Ross in 1841, during his British Antarctic Expedition. It is very uncommon to see in its range and rarely leaves the pack ice, with stray individuals occurring off southeast Australia or sub-Antarctic islands. The Ross seal can reach an average length between 5.5 and 6.9 feet, although some females can reach up to 8.2...
The Weddell seal (Leptonychotes weddellii) is a large true seal in the Lobodontini tribe. It is native to Antarctica, with its range consisting of a large “ring” that surrounds Antarctica. This seal will spend most of its time in the water instead of on land. The Weddell seal appears on the IUCN Red List with a conservation status of “Least Concern”. It is estimated this seal numbers over 800,000 individuals in the wild. First discovered in 1820s by a British sealing captain...
The Antarctic Silverfish, (Pleuragramma antarcticum), is a member of the Notothenioidei family of fish. It is widely distributed around the Antarctic, but has largely disappeared from the western side of the northern Antarctic Peninsula based on 2010 research funded by the National Science Foundation. It is also found throughout the Southern Ocean. It grows to an average size of 6 inches, but has been known to reach lengths of up to 10 inches. It is usually pink with a silver tint, and...
