Pictures of the earth taken from space allow us to see how unique
planet earth looks compared to other planets. This difference is
liquid water on the surface, making the planet appear as a big blue
marble floating in the inky blackness of space.
The presence of liquid water, indicating a surface temperature within the
range of 0-100 degrees Celcius, is unique both in the Solar System and
the currently explored universe. Water has allowed the development
and maintenance of life on this planet.
The first time a primitive human tasted the saltiness of seawater, the
field of chemical oceanography was born. Chemical oceanography is the
study of the chemical components and properties of seawater and their
distributions in the oceans. In this module we will explore some
aspects of the chemistry of the oceans. Join us in our
