33. IceCube Observatory, located at the South Pole, detects cosmic neutrinos which can help answer fundamental questions about the universe.
34. Many species of seabirds, like the albatross, rely on the rich marine life surrounding the continental waters to thrive.
35. Krill in the Southern Ocean, a key species in the marine food chain, are harvested sustainably to manage ecological balance.
36. Diamond dust, a ground-level cloud composed of tiny ice crystals, can be observed in the dry and cold conditions.
37. Subglacial volcanoes are still being discovered, suggesting geological activities continue shaping the land beneath the ice.
38. Only 1% of the land is ever exposed, during the peak melt season in summer.

39. Sea sponges discovered beneath the ice shelves can live for thousands of years, making them some of the oldest living organisms.
40. Explorers and scientists who stay during the winter will experience a period of isolation lasting up to nine months due to the frozen seas and harsh conditions.
41. Permafrost covers much of the exposed rock, preserving a record of ancient biological activity.
42. The region is home to the Clean Air Sector, where some of the cleanest air samples in the world are measured.
43. Geothermal heat from underground provides enough warmth in some areas to support complex subglacial ecosystems.
44. The Southern Hemisphere’s westerly winds are at their strongest around the continent, influencing global weather patterns.

Antarctica Myths

Now that we’ve covered the facts, let’s dive into some common myths about Antarctica and set the record straight.

• Antarctica is Always Dark
  Antarctica experiences extreme seasonal variations in sunlight. During the summer months, the sun doesn’t set for several weeks, giving the continent continuous daylight. Conversely, during the winter, Antarctica is plunged into weeks of darkness.
• Antarctica is Only Ice
  Although about 98% of Antarctica is covered by ice, the continent also has bare rock exposures, known as nunataks, and dry valleys that are entirely ice-free, revealing the underlying rock and soil.
• No One Owns Antarctica
  While no single country owns Antarctica, seven countries have made territorial claims on it. However, the Antarctic Treaty, signed in 1959, ensures that the continent is used for peaceful purposes and scientific research.
• Penguins Are the Only Wildlife in Antarctica
  Besides penguins, Antarctica is home to a variety of wildlife, including seals, whales, and a diverse range of seabirds. These species have adapted to the harsh conditions and play vital roles in the Antarctic ecosystem.
• It’s Impossible to Grow Anything in Antarctica
  Despite the harsh climate, scientists have successfully grown vegetables in Antarctica using hydroponic systems. These soil-free gardens help provide fresh produce for researchers during long missions.
