| History of Oceanography
Oceanography may be one of the newest fields of science,
but its roots extend back several tens of thousands of years when
people began to venture from their coastlines in rafts. These first
seafaring explorers, navigators and oceanographers began to pay attention
to the ocean in many ways. They observed waves, storms, tides, and
currents that carried their rafts in certain directions at different
times. They sought fish for food. They realized that although ocean
water didnt look different from river water, it was salty
and undrinkable. Their experiences and understanding of the oceans
were passed down over thousands of years from generation to generation
in myths and legends.
But it wasnt until about 2,850 years ago (850 BC) that early naturalists
and philosophers started trying to make sense of the enormous bodies of water
they saw from land. Because people could see only endless ocean from the shoreline,
they believed the world was flat. That didnt keep Columbus and others
exploring the oceans in the late 1400s and early 1500s and finally discovering
that the world is not flat, but round- a sphere whose surface is nearly 3/4-covered
by oceans.
Modern oceanography began as a field of science only a little less than 130 years
ago, in the late 19th century, after Americans, British and Europeans launched
a few expeditions to explore ocean currents, ocean life, and the seafloor off
their coastlines. The first scientific expedition to explore the worlds
oceans and seafloor was the Challenger Expedition, from 1872 to 1876, on board
the British three-masted warship HMS Challenger.
But modern oceanography really took off less than 60 years ago, during World
War II, when the U.S. Navy wanted to learn more about the oceans to gain fighting
advantages, especially in submarine warfare. This section of Deeper Discovery
will give you some background and history on the science of oceanography. It
will show you how important early studies were and how far we have come since
then in understanding the oceans and seafloor -- Earths inner space.
