and the branches within it

As you
look at our planet you would not believe that hundreds of years ago this planet
was all water.  As we look at our planet
you notice that majority of the planet is water.  Water covers approximately “70% of the Earth’s
surface and contains about 97% of the Earth’s surface water.” (Nagaraja, 2016)
The study of the ocean and the life that lies within is called Oceanography.
There are many things that depend on this water from the animals to plants that
live in the water (ocean) to every person on this earth.  There are four branches within the oceanography
field of science.  They are biological,
chemical, geological and physical oceanography.

Biological oceanography is the study of the
life within the ocean, which would include living organisms and how they live
within their environment. The understanding of their lives and history, how
they interact with the physical and chemical environment within the ocean of
these organisms.

Chemical oceanography is the studies of the
chemistry of the sea water. It studies the interactions and reactions between
the different substances found within the ocean water.  It also wants to be able to understand how
the chemical are influenced if any by the physical changes within the water.

Geological oceanography is the study of the ocean,
the rocks and minerals, sediment and other things that are located on the
seafloor. It is the study and discovery of how the earth and oceans were
created and what changes they will bring in the future.

Physical oceanography is the study of why and
how the ocean work, the movement, the temperature of the water, waves and
currents. Physical oceanography also looks at the salinity of the water, and the
mass of the water.

takes all these branches and puts them all together to obtain information and research
regarding the water and the life within the water.  By doing this scientist can learn and predict
the weather and climate changes. “Oceanography also is vital to understanding
the effect of pollutants on ocean waters and to the preservation of the quality
of the oceans’ waters in the face of increasing human demands made on them.” (Britannica,

is a very important area to study, we need to know as much as possible about
the world’s oceans as they are very critically for sustaining life on Earth. By
maintaining a balance in the worlds ocean, we would be helping to ensure that we
are maintaining the worlds carbon levels. A sizable percentage of the world’s
oxygen is generated and comes from the oceans. If for some reason the
ecological balance is damaged it could be detrimental to sustaining life on

oceans are so close, so familiar, and so much a part of our lives, yet life
beneath the sea is as foreign to us as another planet. As vast as the oceans
are, there is so much about them we still don’t know, and we are only just
beginning to understand.” (Keller, 2015)

is a large, unique field of study, that has several different branches within it.
It is one of the most interesting fields of science, that everyone should investigate.
