= = = Oceanography! =

= = = = Oceanography is a branch of geography that deals with the ocean. There are four types of oceanography. One is Biological oceanography, or marine biology. The second type is Chemical oceanography, or marine chemistry. A third type is Geological oceanography, or marine geology. Finally the last type is Physical oceanography, or marine physics. Another name for Oceanography is marine science. There is a long history of oceanography.

= Marine Biology =

Marine biology is the study of organisms in the ocean. Marine biology provides food, medicine, and raw materials. Two places it is studied in are estuaries and wetlands. A very large amount of the Earths organism's are found in the ocean. Dew to the depth of oceans they have about 300 times the habitable volume of the terrestrial habitats here on earth. Other of marine biology's sub fields study the physical effects of continual immersion in seawater. Lifeforms that are studied are microscopic life, plants and algae, marine invertebrates, fish, reptiles, seabirds, and marine mammals.

Marine biology is also known as ocean chemistry.It is the study of the science of oceanography. A few things that the cover are turbidity currents,sediments, PH levels, atmospheric constituents, metamorphic activity, and ecology. They discover many new things about the ocean in this field. Marine chemistry work mostly focuses on the analyzing of the normal cycles that occur in the marine environment throughout the year. It also studies how environmental pollution effects these cycles.

= Marine Geology =

Marine geology covers these studies geophysical, geochemical, sedimentological, and paleontological investigations. Marine geology studies the geology of the ocean floor including plate tectonics. These oceanographers study many things in the ocean. They study The Ring of Fire, Mid-ocean Ridge, Mariana Trench, East Pacific Rise, and many more things.

= Marine Physics =

Marine physics is the study of the ocean's physical attributes including temperature-salinity structure, mixing, waves, internal waves, surface tides, internal tides, and currents. They basically study the movement of the water. Also, they study how the moon and sun effect the tides. They want to find out the consequences of the movements of water. They can determine when tides will be the highest. To do this job you need to go to college long enough to at least get your bachelors degree.
