Blue Whale in Antartica

It has been estimated that during the feeding season in Antarctica, a full grown blue whale eats about 4 million krill per day (krill are small shrimp-like creatures), that’s 3600 kg or 4 tons – every day for 6 months. Having laid down a layer of fat from this feeding activity in Antarctica, they then starve for several months; this daily intake would feed a human for about 4 years.

It is estimated at the height of the feeding season in Antarctica an adult blue whale consumes 3-4% of their own body weight in krill per day.

Antarctica Sea-ice

When the Antarctic sea-ice begins to expand at the beginning of winter, it advances by around 40,000 square miles (100,000 square kilometres) per day, and it eventually doubles the size of Antarctica, which adds up to an extra 20 million square kilometers of ice around the land mass,that’s one and a half USA’s, two Australia’s or 50 UK’s worth of ice e area that forms, then breaks up and melts each year.
According to research ,sea ice around Antarctica has expanded at a rate of around 100,000 sq kms (38,610 sq miles) a decade since the 1970s and it is due to hole in the ozone.

Antarctica and Meteorites

Antarctica is the best place in the world to find meteorites. Dark meteorites show up against the white expanse of ice and snow and don’t get covered by vegetation. In some places, the way the ice flows concentrates meteorites there. The ice makes them gather in one place,it is believed that the first meteorites were discovered by a Japanese science team sent to Antarctica to study glaciers.

According to scientists, (meteorite found in Antarctica contains Martian fossils and organic chemicals) and it is believed that it contains important traces of life on mars.

Ice Cap at Antarctica

Ninety per cent of the world’s ice and approximately 80 per cent of its fresh water is locked up in the Antarctic ice sheet; the ice cap at Antarctic contains 29 million cubic kilometers of ice. This constitutes nearly between 60 – 70% of all of the fresh water in the world. If all the ice were to melt, the level of the world’s oceans would rise by nearly 60 m. However, the response of the ice sheet to global warming is the largest unknown in projecting future sea level over the next 100–1000 years.

Weight of the Ice at Antarctica

If the weight of the ice were removed it is estimated that the underlying rock would rise on average by 1000 m. This process – known as isostatic uplift – would take many tens of thousands of years. Without the ice we would see the single mass of East Antarctica and a smaller archipelago of rugged mountainous islands – West Antarctica.

Some more :happy: :

Antarctica is the highest, driest, windiest, emptiest, coldest place on earth.

An ice sheet covers all but 2.4 percent of Antarctica's 14 million square kilometers.

At its thickest point the ice sheet is 4,776 meters deep and averages 2, 160 meters thick. This is 90 percent of all the world's ice and it is 70 percent of all the world's fresh water.

There are lots of penguins, whales, seals, krill (the main food for whales), and even fish in Antarctica's waters, but there are no land mammals and, as far as scientists know, no native peoples.

Eskimos and polar bears are found in the ARCTIC, not the Antarctic.

The mean annual temperature at the South Pole is minus 56 degrees F. During the Austral Summer, temperatures at McMurdo base, on the Ross Sea, may get as high as 40 degrees F, while at the South Pole, at the Amundsen- Scott station, temperatures may reach 0 degrees F.

The area below 60 degrees south enjoys one long day and one long night each year. The sun sets in March and rises in October.

The seasons in Antarctica are the opposite of the seasons in the Northern hemisphere--summer is October through February. Winter is March through September.

The continent is roughly 14 million square kilometers (5.4 million square miles). The USA is only 9.36 million square kilometers (3.6 million square miles). The distance from Washington, D.C. to McMurdo station is approximately 14,830 kilometers, or 9,920 miles.

Scientists work on all kinds of unique projects in Antarctica, including penguins, Antarctic cod (they have a special antifreeze agent in their blood!), whales, seals, global warming, climatology, meteorites, glaciology, astronomy, volcanoes, UV radiation, and more. Scientists also study humans in Antarctica, doing research on how the human body adapts to cold and how the human mind and heart react to extreme isolation.

The Antarctic continent wasn't even actually seen until 1820. No man set foot in Antarctica until 1895. The first human landing there is claimed by Henryk Bull, with a party from a whaling ship. They landed at Cape Adare . It was 1935 before the first woman set foot there. Her name was Catherine Mikkelson, and she was the wife of a Norwegian whaling captain. The South Pole was first reached by a Norwegian named Roald Amundsen in 1911, and shortly after by British explorer Robert Scott.
