Oceans cover almost 71 percent of the Earth's surface. Travelers on
land can find their way by recognizing landmarks and navigating
with the help of maps, but there are no landmarks at sea and
mariners must find other signposts to guide them. Many centuries
ago, navigators learned to steer by the sun and stars and by
compasses that align themselves with the Earth's magnetic field.
Equipped with simple instruments, surveyors defined the boundaries
of the ocean while scientists mapped the ocean currents. Oceans
explores some of the mapmakers, scientists, and adventurers who
dedicated their lives to improving our understanding of the oceans.
This new resource begins with the long process of mapping the
oceans and the many problems that had to be solved before this
could be achieved satisfactorily. This full-color book details some
of the greatest surveyors and mapmakers, including Captain James
Cook and Robert FitzRoy, as well as some of the explorations that
made a huge impact on ocean research. Ocean basins are also
examined in this comprehensive resource. The chapters include:
Mapping the Oceans, The Origin of the Oceans, Studying the Ocean
Floor, Measuring the Depth and Flow, Journeys to the Bottom of the
Sea, Life in the Abyss, Monsters, and Modern Explorers.
