A lead weight on a string will let you measure a pond's depth. But how to gauge the ocean's depths -- or total size? Using satellites, oceanographers have pinned the number down.

Using lead weights and depth sounders, scientists have made surprisingly accurate estimates of the ocean's depths in the past. Now, with satellites and radar, researchers have pinned down a more accurate answer to that age-old query: How deep is the ocean? And how big?

Each year the temperature of the deep layer of the Western Mediterranean increases by 0.002ºC, and its salt levels increase by 0.001 units of salinity. These changes, although minimal from year to year, have been continuously and constantly occurring at a faster pace since the 1990s.
