Why is Antarctica at the bottom?

Surface water is enriched in salt from sea ice formation. Due to its increased density, it flows down the Antarctic continental margin and continues north along the bottom. It is the densest water in the free ocean, and underlies other bottom and intermediate waters throughout most of the southern hemisphere.

Why is Antarctica not on most maps?

The new map covers approximately 98\% of Antarctica to a latitude of 88 degrees south — just a small area right near the South Pole is missing due to a lack of satellite coverage.

Why isn’t the Arctic on the map?

On Google Maps, anything north of 85° N, or south of about 83° S, isn’t visible at all. The real reason that the north and south poles look different is that the south pole is covered by a giant land mass, while the north pole isn’t.

When was Antarctica put on the map?

The mapping of Antarctica was obstructed by its covering of ice. The rock continent under the ice was not fully mapped until the 1980s. This was made possible by the development of technologies such as echo sounding (invented by a team of Scientists from the Scott Polar Research Institute at Cambridge University).

Who mapped Antarctica?

In November 1820, Nathaniel Palmer, an American sealer looking for seal breeding grounds, using maps made by the Loper whaling family, sighted what is now known as the Antarctic Peninsula, located between 55 and 80 degrees west.

Where is the opposite of Antarctica?

Arctic
The Arctic and Antarctic are geographic opposites, and not just because they sit on opposite ends of the globe. They also have opposite land-sea arrangements. In the Arctic there is an ocean surrounded by continents, while the Antarctic is continent surrounded by oceans.
