Looking at our Earth from space, it is obvious that we live on a water planet. Ocean covers over 70% of the Earth's surface and contains about 97% of the Earth's surface water. Life in the oceans can be found from the surface to the extreme environments at the bottom of the deepest submarine trench. It is not surprising that the oceans ...

Oceanography: Science of the Oceans. Oceanography is the study of Earth's oceans - their composition, movement, organisms and processes. The oceans cover most of our planet and are important resources for food and other commodities. They are increasingly being used as an energy source.
The Scripps Institution of Oceanography (SIO) offers a rigorous and interdisciplinary curricula in the Earth Sciences. Students can do a major in Earth Sciences or specialize in Earth Sciences within another major (i.e. Physics, Environmental Systems). Earth sciences encompass broad scientific study of the origin and evolution of the earth system and its life forms.
NASA's Aquarius instrument has been orbiting earth since June 2011, measuring changes in salinity, or salt concentration, in the surface of the oceans. In fall 2011, the Aquarius team released this first global map of ocean saltiness, a composite of the first two and a half weeks of data since the instrument became operational on August 25, 2011.
Carbon atoms are constantly being cycled through the earth's ocean by a number of physical and biological processes. The flux of carbon dioxide between the atmosphere and the ocean is a function of surface mixing (related to wind speed) and the difference the concentration of carbon dioxide in the air and water The concentration in the ocean depends on the atmosphere and ocean carbon dioxide ....
The most important light-absorbing substance in the oceans is chlorophyll, which phytoplankton use to produce carbon by photosynthesis. Due to this green pigment - chlorophyll - phytoplankton preferentially absorb the red and blue portions of the light spectrum (for photosynthesis) and reflect green light. So, the ocean over regions with high concentrations of phytoplankton will appear as ...

Physical oceanography is the study of the physical properties and dynamic processes of the oceans. Physical oceanographers study the interaction of the ocean with the atmosphere, how the ocean stores and releases heat, the physical properties (or chemical content) of water throughout the ocean, and the formation and movement of currents and coastal dynamics.
