How much of Antarctica is explored?

Answer 1

More than 80% of the ocean remains unexplored.

One of the biggest challenges of ocean exploration comes down to physics. Dr. Gene Carl Feldman, an oceanographer at NASA’s Goddard Space Flight Center, explains that the ocean, at great depths, is characterized by zero visibility, extremely cold temperatures, and crushing amounts of pressure.

“In some ways, it’s a lot easier to send people into space than it is to send people to the bottom of the ocean,” Feldman told Oceana. “The intense pressures in the deep ocean make it an extremely difficult environment to explore.”

Answer 2

Not much, actually.

The coasts are well known and heavily documented, as are several trekking routes to the South Pole. There is knowledge of the continent between Mirny Station and Vostok Station, because Vostok is supplied by over-land transit from Mirny, which is on the coast. Both are supported by the Russian government.

The area around Vinson Masiff is also fairly well-known, since it is included in the seven summit count of the highest mountain on each continent.

Because 98% of the continent is covered with an ice sheet, not much is known about the continent that lies beneath it.

Answer 3

I believe around ten percent of the upper most part of the ocean has been explored and ninty percent remains.
