Two-thirds of the earth's surface is covered by the waters of the
oceans which greatly affect our lives. As human populations grow more
and more rapidly/ as our technological development takes place at a
faster pace, as man moves forward with his relentless search for greater
understanding of the universe in which he lives, detailed knowledge and
understanding of the oceans and their contents will assume much greater
importance. The oceans present a challenge to man which in magnitude
may approach that of space.
