Summary: | The Southern Ocean (SO) comprises more than 10% of the world's oceans and plays a substantial role in the Earth System. In total, it covers an area of 34.8 million km2. The shelves around Antarctica are on average 450 - 500 m deep, but exceed 1000 m in places. Of the total SO area. the continental shelf (~1000m in depth) covers 4. 59 million km2, the continental slope (1000 - 3000 m in depth) covers 2.35 million km2 and the deep sea (23000 m in depth) covers approximately 27.9 million km2 (Clarke and Johnston, 2003). Sea ice covers roughly half of the Southern Ocean during winter and approximately 10% during the summer. |
