Question

5. White any four features of Southern Ocean.​

Answer 1

Answer:

The Southern Ocean has typical depths of between 4,000 and 5,000 m (13,000 and 16,000 ft) over most of its extent with only limited areas of shallow water. The Southern Ocean's greatest depth of 7,236 m (23,740 ft) occurs at the southern end of the South Sandwich Trench, at 60°00'S, 024°W.

The Southern Ocean is known for its uniqueness in the diversity of organisms. Cold adaptation and evolution in thermal isolation over tens of millions of years has resulted in an ecosystem that is unparallelled.

Antarctic krill feeds under the ice during winter, but has been found feeding as deep as 3,000m in summer.
