According to Encyclopedia Britanica:

{{Cquote|The structure of the ocean floor includes a continental shelf usually less than 160 miles (about 260 km) wide that attains its maximum width of more than 1,600 miles (2,600 km) in the vicinity of the Weddell and Ross seas. There are oceanic basins farther north that are as much as 14,800 feet (4,500 metres) deep, defined by oceanic rises and often marked by ranges of abyssal hills. There are also narrow oceanic trenches with high relief, such as the South Sandwich Trench on the eastern side of the South Sandwich Islands. Other relief features include oceanic plateaus that rise from the oceanic basins to depths of less than 6,650 feet (2,000 metres) below sea level and form rather flat regions, which are often covered by relatively thick sedimentary deposits. The most extensive such plateau is the Campbell, or New Zealand, Plateau, which rises southeast of New Zealand and extends southward beyond the Campbell Islands.<ref>[https://www.britannica.com/place/Southern-Ocean Southern Ocean]</ref>}}

The cruise company Hurtigruten says about the Southern Ocean:

{{Cquote|The fourth-largest ocean after the Pacific, Atlantic, and Indian Oceans, the Southern Ocean covers a minuscule 4 percent of the planet’s surface — about the size of the United States or China. The only smaller ocean, the Arctic Ocean, lies at the Antarctic’s antipode in the northern hemisphere. While small in geographic size, the Southern Ocean actually holds 150 times more water than all of the rivers in the world combined.
