- While the circumpolar current is the dominant feature of the Southern Ocean, there are other important flows in the north-south direction and in the vertical plane. The average depth of the ocean ranges from 2,000 to 4,000 metres.he temperature of the water in the Southern Ocean has a powerful influence on the climate of much of the earth. The current is not always stable. It can develop disturbances called waves or eddies which involve the entire water column.

- The RAF's Red Falcons jumped over Cape Agulhas - the small peninsula at the bottom of the photograph. The oceans don't respect any lines that are drawn by man... Yes, somebody did draw a line — to demarcate where the Indian and Atlantic Oceans meet. From the coast of the Antarctic continent northwards, along the meridian of 20°E to Cape Agulhas (34°50’S – 20°00’E), the southern extremity of the Republic of South Africa, in Africa (the common limit with the South Atlantic Ocean).

Arctic vs. Antarctic While thickness varies significantly within both regions, Antarctic ice is typically 1 to 2 meters (3 to 6 feet) thick, while most of the Arctic is covered by sea ice 2 to 3 meters (6 to 9 feet) thick. Some Arctic regions are covered with ice that is 4 to 5 meters (12 to 15 feet) thick.he Arctic is a semi-enclosed ocean, almost completely surrounded by land. As a result, the sea ice that forms in the Arctic is not as mobile as sea ice in the Antarctic. Although sea ice moves around the Arctic basin, it tends to stay in the cold Arctic waters.

The 9 Most Extreme Places on the Planet The Bentley Subglacial Trench in Antarctica is phenomenally thick ice, going 8,383 feet deep. It’s the lowest point on earth that isn’t covered by ocean, but the honor still goes to the Dead Sea for lowest point, as the Dead Sea is technically “on” land and the Bentley Trench is technically covered with water (ice).

- Under the surface of Antarctica, all is not cold and quiet. In fact, there is an active volcano in Antarctica: Mount Erebus, which is 3,794 meters (12,447 feet) in height, is located in East Antarctica, on the edge of the Ross Ice Shelf—a place where ice extends far out over the ocean. Antarctica is also home to Lake Vostok, one of the world's largest lakes. Lake Vostok is roughly the size of North America's Lake Ontario, but it is not a lake for sailing boats. It lies 4 kilometers (2 miles) below the continental ice sheet.

Geography of the World's Oceans It has a total area of 7,848,300 square miles (20,327,000 sq km) and an average depth ranging from 13,100 to 16,400 feet (4,000 to 5,000 m). The deepest point in the Southern Ocean is unnamed but it is in the south end of the South Sandwich Trench and has a depth of -23,737 feet (-7,235 m).

Ocean fisheries The Southern Ocean is the fourth-largest ocean, covering 20,327,000 square kilometers. It is typically between 4,000 and 5,000 meters deep with only limited areas of shallow water. The Antarctic continental shelf is narrow and unusually deep, its edge lying at up to 800 meters, compared to a global mean of 133 meters.

- If all of the Antarctic ice melted, sea levels around the world would rise about 61 meters (200 feet). But the average temperature in Antarctica is -37°C, so the ice there is in no danger of melting.

Antarctic Circumpolar Current Antarctic Circumpolar Current. The Antarctic Circumpolar Current (ACC) is an ocean current that flows clockwise from west to east around Antarctica. An alternative name for the ACC is the West Wind Drift. The ACC is the dominant circulation feature of the Southern Ocean and has a mean transport of 100-150 Sverdrups (Sv, million m³/s), making it the largest ocean current.

- The second reason is elevation. As you go up in altitude, the air temperature decreases (by 6.5C for each 1 km). Since the average elevation of Antarctica is 2.3 km, the air is much colder compared to the Arctic Ocean, which is at sea level.

Pacific Ocean Of the three oceans that extend northward from the Antarctic continent, the Pacific is by far the largest, occupying about a third of the surface of the globe. Its area, excluding adjacent seas, encompasses about 63.8 million square miles (165.25 million square km).

Arctic vs. Antarctic The Antarctic is almost a geographic opposite of the Arctic, because Antarctica is a land mass surrounded by an ocean. The open ocean allows the forming sea ice to move more freely, resulting in higher drift speeds. However, Antarctic sea ice forms ridges much less often than sea ice in the Arctic.

Why is southern sea ice increasing? The news of expanding Antarctic sea ice stole headlines from global warming alarmists who asserted Arctic sea ice had reached its lowest extent since 1979.' (James Taylor). The most common misconception regarding Antarctic sea ice is that sea ice is increasing because it's cooling around Antarctica. The reality is the Southern Ocean surrounding Antarctica has shown strong warming over the same period that sea ice has been increasing. Globally from 1955 to 1995, oceans have been warming at 0.1°C per decade.

"Ocean ""Conveyor Belt"" Sustains Sea Life, Study Says" There, relatively warm waters of the deep-ocean rise to the cold sea surface just south of the current and balance the sinking of surface water along the edge of Antarctica and to the north. As the deep ocean waters come to the surface, they bring with them all the nutrients that have been broken down and dissolved, Gordon said. These waters are transported into the barrier layer, or thermocline, of the more northern oceans, where the nutrients are then absorbed by phytoplankton at the surface.

The average depth of the Atlantic ocean in yards? 7! The current deepest point on any ocean floor is Challenger Deep (named after HMS Challenger) in the Mariana Trench. That is 10,911 metres (35,797 ft) or 7 miles deep. And … also in the Pacific Ocean. So I don't think the average depth of the Atlantic is 7 miles. The Average Depth of the Atlantic is about 11,810 feet or 2.236 miles. 6 people found this useful.

- Antarctic fish have lived at between +2°C and -2°C for 5 million years (-2°C is the freezing point of sea water, being below zero because of the salt content of the water). #4 When you drill into the ice in Antarctica, you will get a long cylinder of ice, called an ‘Ice Core’. These Ice Cores give an indication of the what life was like in the past, going back tens of thousands of years, giving valuable information about the Earth’s climate throughout history.
