The frozen continent of Antarctica was the last continent humanity set foot on. The first documented landings made below the Antarctic Circle took place in 1820, when Admiral Fabian Gottlieb von Bellingshausen and the crew of the Vostok and Mirny, as part of the Russian Antarctic Expedition, made land at Peter I Island and Alexander Island.
East Antarctica is significantly larger than West Antarctica, and similarly remains widely unexplored in terms of its volcanic potential. While there are some indications that there is volcanic activity under the East Antarctic Ice Sheet, there is not a significant amount of present information on the subject.
Parts of icy Antarctica are turning green with plant life as the region is gripped by extreme heat events, new research shows, sparking concerns about the changing landscape on this vast continent.
Soils in Antarctica are nearly two-dimensional habitats, with most biological activity limited to the top four or five inches by the permanently frozen ground below. [4] Environments can be limiting due to soil properties such as unfavorable mineralogy, texture, structure, salts, pH, or moisture relationships. [5]
A portion of the world's iciest, coldest continent is "greening" at a dramatic rate because of global warming, scientists announced in a recent study. In fact, the research showed that vegetation ...
Eastern Antarctica is to the right of the Transantarctic Mountains and Western Antarctica is to the left. Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle (one of the five major circles of latitude that mark maps of the world), Antarctica is surrounded by the Southern Ocean.
These lakes could threaten the future stability of parts of the Antarctic ice sheet.
The continent of Antarctica is so cold that it has supported only 2 vascular plants for millions of years, and its flora presently consists of around 250 lichens, 100 mosses, 25–30 liverworts, and around 700 terrestrial and aquatic algal species, which live on the areas of exposed rock and soil around the shore of the continent.
