Oceanography

Have you ever heard a sentence like Osenography ... Maybe some of us have never heard that sentence or maybe have heard but forgotten, hearing such a name becomes interested in us to discuss it, calculating knowledge sharing. To find out, let's consider the origin of words from Oceanography. The sentence can be concluded that "Ocean = Sea, Graph = General Picture", and it can be concluded oceanography is the study of all phenomena and processes that occur both on the surface of the sea, in columns of sea water, and on the seabed. Oceanography therefore includes all branches of science that study the ocean and its surroundings in the ocean. The sea is very interesting for people because they are so beautiful behind sunrise and sunset, back to oceanography, as mentioned above that oceanography is a study of the ocean that can divided through several branches of the same variety below,  **-Oseanografi Fisik** **-Oseanografi Kimia** **-Biologi Oseanografi (Oseanografi Biologis)** **-Oseanografi Geologi (Oseanografi Geologi)** The first is "Oceanography Physics" is a branch of oceanography that studies everything about phenomena and processes of physics at sea. Things that become the object of study include: **1. Ocean currents** **2. Waves** **3. Install** The spreading and propagation of light and sound in the ocean, as well as the physical properties of seawater such as Temperature, Clarity, freezing point, electrical conductivity, and other physical properties are included in that branch of science.  Both Chemical Oceanography are studying everything about the substances contained in seawater, the origin of its formation, the environmental factors that influence it, the reaction process that occurs, and the factors that influence or control the spread of these substances that are in the oceans, both deep and shallow oceans.  Then the third, Oceanography Biology is a branch that studies about living things in the oceans both vegetable and animal. The things studied include the types, the way of breeding, the spreading area, the relationship between each other and with the environment. This branch is often also called the Marine Biology, maybe this science we often hear and we learn. And the latter is the fourth, Geological Oceanography, is a branch that studies the geology of the ocean floor. The things studied, for example, about the shape of the ocean floor, the processes that influence its formation, the deposits contained above and below the sea floor, this science is often studied by geologists.  The four branches of science such as Physical oceanography, Chemical Oceanography, Oceanography Biology (Oceanography Biology) and Oceanography Geology (Geological Oceanography) are actually only for practical purposes, because in essence in each branch of science is still interlinked , and closely related to each other. For example an expert Biological Researcher, of course, desperately need a description of the state of the current, dissolved chemicals, and the basic state of a creature that became the object of his research. And so on from one branch to another there is a linkage with each other, so that someone who is engaged in one of the branches of oceanography mentioned above must also master the basics of the four branches of science mentioned above. So would a brief discussion about the sea that we often see and which we often visit, may be useful.
