Krill, in turn, are essential for supporting larger predators such as fish, seals, and whales, making phytoplankton vital for the entire Antarctic marine food web.

When you get too cold, it is referred to as hypothermia. This condition occurs when your body loses heat faster than it can produce it, causing your core temperature to drop to dangerously low levels. Symptoms include shivering, confusion, fatigue, and in severe cases, can lead to unconsciousness or death if not treated promptly. It's crucial to seek warmth and medical attention if hypothermia is suspected.

Antarctica is expensive due to its remote location, harsh climate, and the logistical challenges associated with conducting research and operations there. The cost of transportation, specialized equipment, and maintaining support facilities adds to the overall expenses. Additionally, stringent environmental regulations and the need for safety measures further drive up costs. Funding for scientific research in Antarctica often comes from government grants, which can be limited and competitive.

The sole physical feature of Antarctica, often referred to as "ice," is its vast ice sheet, which covers approximately 98% of the continent. This ice sheet is the largest single mass of ice on Earth, containing about 60% of the world's fresh water. Its thickness can reach up to 4.8 kilometers (about 3 miles) in some areas, and it plays a crucial role in regulating global climate and sea levels.

The three early explorers who sighted Antarctica were Fabian Gottlieb von Bellingshausen and Mikhail Lazarev from Russia, who first saw the continent in 1820, as well as Edward Bransfield from Britain, who explored the region shortly thereafter. Their expeditions marked significant milestones in the exploration of the Antarctic region during the early 19th century. Additionally, American explorer John Davis is also credited with making landfall on Antarctica in 1821.

A large sheet of flowing ice is called a glacier. Glaciers form from accumulated snow that compresses into ice over time and can move slowly across land due to gravity. They are found in polar regions and mountainous areas, playing a crucial role in the Earth's climate and hydrology.

A small ice mass that spreads outward on a land surface is known as a glacier. Glaciers form from accumulated snow that compresses into ice over time, and they move slowly due to gravity. They can vary in size and are typically found in mountainous regions or polar areas. As they advance, they can shape the landscape through erosion and deposition of sediment.

Antarctica's highest mountain is Mount Vinson, which stands at an elevation of 4,892 meters (16,050 feet) above sea level. It is located in the Ellsworth Mountains, specifically in the Sentinel Range.
