About the Continent - According to the USAP

Antarctica is the coldest, windiest, harshest continent, and with little precipitation (roughly 2 inches per year) is the driest place on earth. It is roughly 14 million sq km (5.4 million sq. mi.), has an average elevation of more than 2,000 m (6,500 ft.), and 98% of the landmass is covered by an ice sheet estimated to be 29 million cu km (7 million cu. mi.).

The average annual temperature at South Pole Station is -56°F. During the austral summer, temperatures at McMurdo Station may reach as high as 50°F, while at South Pole Station the summer temperature may reach 0°F. Palmer Station has a milder climate, with summer temperatures reaching as high as 55°F.

Temperature patterns vary so widely because the continent is covered in continuous darkness during the austral winter and continuous sunlight during the austral summer, with a few weeks of sunrises and sunsets in between seasons.

Plant life in Antarctica is limited, consisting of mostly algae, lichens, and mosses, and there are only a few known species of flowering plants. As far as animal life, only microscopic animals (such as mites and worms) and insects exist on the land; however, the Southern Ocean surrounding Antarctica is full of sea life, including phytoplankton, zooplankton, fish, squid, seals, whales, and seabirds.

  1. Does one ever see land as we know it, you like dirt, in this climate? Which season are you in?
