Oceans make up most of the surface of our blue planet. They may
form just a sliver on the outside of the Earth, but they are very
important, not only in hosting life, including the fish and other
animals on which many humans depend, but in terms of their role in
the Earth system, in regulating climate, and cycling nutrients. As
climate change, pollution, and over-exploitation by humans puts
this precious resource at risk, it is more important than ever that
we understand and appreciate the nature and history of oceans.
There is much we still do not know about the story of the Earth's
oceans, and we are only just beginning to find indications of
oceans on other planets. In this book, geologists Jan Zalasiewicz
and Mark Williams consider the deep history of oceans, how and when
they may have formed on the young Earth - topics of intense current
research - how they became salty, and how they evolved through
Earth history. We learn how oceans have formed and disappeared over
millions of years, how the sea nurtured life, and what may become
of our oceans in the future. We encounter some of the scientists
and adventurers whose efforts led to our present understanding of
oceans. And we look at clues to possible seas that may once have
covered parts of Mars and Venus, that may still exist, below the
surface, on moons such as Europa and Callisto, and the possibility
of watery planets in other star systems.
