How deep is the Antarctic ocean?

Answer 1

Antarctica is a continent of approximately 14,000,000 sq km. The Antarctic Ice Sheet consists of about 13.72 million sq km of permanent ice up to over 4 km thick representing 90% of the world's ice.

Answer 2

The average depth of the Antarctic Ocean is 1038 meters, or 3410 feet. The deepest point is the Eurasian Basin which measures as far down as 5450 meters, or 17900 feet.

Sea-temperatures vary from about −1 to 10 °C and because of the region, it's Climate may change as you can see. Allowing it's waters to merge with the other region, it may be most likely Cold, as it can meet Ice Cold Waters coming from the Ice Piers.

There isn't an Antarctic Ocean, Antarctica is surrounded by the Southern Ocean. All the facts and figures above apply to the Arctic Ocean.

Answer 3

Under Vostok Station in Antarctica, lies Lake Vostok, some 4000m below the surface of the ice. The ice surface here is about 3500m above sea level, so the lake surface is below sea level. It is up to 800 m deep in itself, and averages 344 m in depth. Its area is about 15690 sq km, that is about the size of Lake Ontario.

Vostok station is near the maximum height of the Polar Plateau, so the short answer to your question is 'about 3500m'. Plans are afoot to sample the water of this lake, but GREAT CARE must be taken to not contaminate the water, for it is probably up to 15 million years old - but wait till Feb 2012 for an update.

Answer 4

There is no sea below Antarctica, as there is no sea below any of the seven continents on Earth.

However, there are sub-glacial lakes below the ice cap that covers 98% of Antarctica. These lakes rest on warm earthen basins, for example, Lake Vostok.

From its Wikipedia page, here are a few details about that lake:

• Coordinates 77°30′S 106°00′E
• Lake type Subglacial rift lake
• Basin countries Antarctica
• Max. length 250 km (160 mi)
• Max. width 50 km (30 mi)
• Surface area 12,500 km2 (4,830 sq mi)
• Average depth 432 m (1,417 ft)
• Max. depth 510 m (1,700 ft)[1] to 900 m (3,000 ft)
• Water volume 5,400 km3 (1,300 cu mi)[2] ± 1,600 km3 (400 cu mi)
• Residence time 13,300 yrs
• Surface elevation ~ -500 m(-1,600 ft)

Answer 5

From Wikipedia, below:

"The Antarctic continental shelf appears generally narrow and unusually deep, its edge lying at depths up to 800 m (2,600 ft), compared to a global mean of 133 m (436 ft)."

Answer 6

There is no standard: but ice shelves drop about 300 feet into deep water, and this area has never been explored.

Answer 7

The depth of the ice at the South Pole is about two miles.

Answer 8

One ice shelf, the Ross Ice Shelf -- about the size of France -- has been estimated to be 750 m (2,450 ft) thick, according to its Wikipedia page.

Answer 9

around 1000,0000,0000km
