- Adelie — A proper noun used primarily in geographical and zoological contexts, historically linked to Adélie Land, a region in Antarctica named by explorer Jules Dumont d'Urville in honor of his wife, Adèle. In zoology, it identifies the Adélie penguin (Pygoscelis adeliae), a common medium-sized penguin species that inhabits the coasts of the Antarctic continent. As a given name, it is a spelling variant of Adela.
- Iceberg — A huge mass of ice structurally detached from a polar glacier or a continental ice shelf, drifting on the surface of oceans, carried by marine currents. From a physical standpoint, it is characterized by the fact that only a small part of its total volume (approximately ten percent) is visible at the water's surface, while the massive, microscopic core is submerged, representing a major danger to global maritime navigation.
- Almirante Brown — A proper name of high resonance in the Argentine context, originally attributed to Admiral William Brown, a national hero and founder of the Argentine Navy; the term also designates a partido (district) in Buenos Aires Province, a scientific research station in Antarctica, and Club Almirante Brown, a well-known sports club from San Justo, majorly recognized for its football team.
- Amundsen-Scott — The permanent American scientific research station located precisely at the geographical South Pole in Antarctica, named in honor of the two great rivals of polar exploration, Roald Amundsen and Robert F. Scott. This base represents the southernmost permanently inhabited place on Earth, serving as a crucial hub for advanced research in astrophysics, seismology, and global climatology.
- Antarctica — The southernmost continent on Earth, situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean. It is the coldest, driest, and windiest continent, covered over 98% by a massive ice sheet that stores most of the planet's fresh water reserves. It has no permanent human population and is governed internationally by the Antarctic Treaty for exclusively peaceful and scientific purposes.
- Antarctica — An alternative geographical designation used in the Romanian language for the continent of Antarctica, denoting the continental landmass situated in the southern polar region. While modern scientific language prefers 'Antarctica', this form is often preserved in cartographic, popular science, or older geographical literature to describe the actual landmass beneath the ice sheet.
- Azorella — A genus of perennial herbaceous plants in the family Apiaceae, native to alpine and subantarctic regions of South America, New Zealand, and islands of the southern Indian Ocean; these plants grow extremely slowly and form dense, compact, cushion-like mats (such as Azorella compacta or Yareta), perfectly adapted to withstand violent winds and freezing temperatures.
