Ocean Facts
Area: about 140 million square miles (362 million sq km), or nearly 71% of the Earth's surface.
The longest continuous mountain chain known to exist in the Universe resides in the ocean at more than 40,000 miles long.
Water pressure at the deepest point in the ocean is more than 8 tons per square inch, the equivalent of one person trying to hold 50 jumbo jets.
A swallow of seawater may contain millions of bacterial cells, hundreds of thousands of phytoplankton and tens of thousands of zooplankton.
More than 90 percent of the trade between countries is carried by ships and about half the communications between nations use underwater cables.
By 2010, 80 per cent of people will live within 60 miles of the coast.
Tropical coral reefs border the shores of 109 countries, the majority of which are among the world's least developed. Significant reef degradation has occurred in 93 countries.
The High Seas -- areas of the ocean beyond national jurisdiction -- cover almost 50 per cent of the Earth's surface. They are the least protected part of the world.
