The Oceans

Discusses early explorations of the ocean floor and raises questions which researchers are now trying to answer. Shows that the history of the earth's surface is better preserved under the sea than it is on land because under water mountains are not eroded by rain and ice. Describes research methods and tools such as aqua-lungs, diving bells, bathyscaphes and echo sounders.
