The Traditional "Four Branches"The science of Oceanography involves many different disciplines

such as: Physics, Chemistry, Geology, Biology, Math, Geography & Astronomy

1. Geological Oceanography: Sea Floor Topography, Tectonics / Ocean Basin Evolution, Geophysics, Marine Sediments, The Coastal Environment

2. Chemical Oceanography: Origin of Seawater, Salinity, Trace Elements, Nutrients, Dissolved Gases, Inorganic Precipitates

3. Physical Oceanography: The Movement of Seawater, Currents, Waves, Tides, Temperature, Density, Structure, Sea Level History

4. Biological Oceanography: Birds & Mammals, Reptiles, Ichthyology = Study of Fishes, Phycology = Study of Plants, Invertebrates, Plankton & Primary Production
