The Antarctic is a cold, inhospitable place. It has a low biodiversity, which means that, compared to other parts of the world, only a small number of species are found here. On the continent of Antarctica itself, very little life exists in the frozen interior. Most species are found on ...
Compared with the other continents Antarctica is remarkably free from earthquakes, especially in view of the active volcanism and other signs of instability. On the hypothesis that earthquake activity is affected by variations in the thickness of the ice-cap, any future earthquake of even moderate ...
The general consensus on Ushuaia is that there’s not much there. This is true – it’s nothing compared to Buenos Aires or even the smaller Argentine cities of Mendoza or Bariloche. But I’ve always enjoyed exploring the small towns (I find them much more manageable than the major metropo...
Artwork on the wall at Base A at Port Lockroy, which dates from the 1960’s, depicts British actress Diana Dors, who was often compared to Marilyn Monroe. Proceeds from the shop are used to maintain the museum operations. The post office, which issues souvenir Antarctica passport stamps, ha...
Long hours of hot sunshine and searing winds give Australia an extremely high rate of evaporation, far more than in most other countries. It is estimated that approximately 87% of Australia's rainfall is lost through evaporation, compared with just 16% in Africa and 48% in North America, ...
other oceans, which are divided by the surrounding continents, the extent of the SouthernOcean is determined by the Antarctic Circumpolar Current (ACC) - the Earth's longest and strongestoceanic current.The ACC encircling Antarctica and flowing from the west to the east was set 34 million years...
On average, Antarctica is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents.[1] Since there is little precipitation, except at the coasts, the interior of the continent is technically the largest desert in the world. There are no permanent...
Previous studies have reported on bioaerosols in Antarctica.Bottos et al. (2014)examined bioaerosols in the McMurdo dry valley and found that the most abundant bacterial taxa are common to those documented in other continents, suggesting that a distinct bioaerosol community occurs globally.Pearce ...
Polyphacelus stormensis Yao, Taylor et Taylor, a permineralized dipterid fern from the Lower Jurassic of the central Transantarctic Mountains, has been compared to Clathropteris (Yao et al., 1991). We here report newly discovered dipterid fern fossils from the Lower Jurassic of the Trans...
Geochemical compositions of these mafic dykes are compared and they show good relationships with each other. Similarities in petrological and geochemical characteristics of Precambrian mafic dykes of East Antarctica and Central-East India strongly support juxtaposition of these two continents....
