Dear friend, many thanks for you question and I really appreciate your career planning at this young stage. Let me tell you something about the oceanography. It is also known as oceanology and marine science, is branch of Earth Science that studies the ocean. It covers a wide range of topics, including marine organisms and ecosystem dynamics; ocean currents, waves and geophysical fluid dynamics; plate tectonics and the geology of the sea floor and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect the multiple disciplines that oceanographers blend to further knowledge of the world ocean and understanding of processes within; astronomy, biology, climatology, geography, geology, hydrology, metrology and physics.

The main branches of oceanography is as follows:

Biology oceanography: it investigates the ecology of marine organisms in the context of the physical, chemical and geological characteristics of their ocean environment. It is closely aligned with marine biology, though the latter has more emphasis on the biology of individual marine organisms.

Chemical oceanography: or marine chemistry, is the study of the chemistry of the ocean and the chemical interaction with the atmosphere.

Geological oceanography: or marine geology, is the study of the geology of the ocean floor including plate tectonics and paleoceanography.

Physical oceanography: or marine physics, studies the ocean's physical attributes including temperature salinity structure, mixing, surface waves, internal waves, surface tides, internal tides, and currents.

These branches reflect the fact that many oceanographers are first trained in the exact sciences or mathematics and then focus on applying their interdisciplinary knowledge, skills and abilities to oceanography.

In India, the premier Institute is The National Institute of Oceanography (NIO) is one of the 37 constituent laboratories of the CSIR (Council of Scientific and Industrial Research) an autonomous research organization. The institute has its headquarters in the coastal state of Goa, established in January, 1966.



Now you have got an idea, about the oceanography. Now you can study any branch (chemistry, physics, geography, geology, mathematics and biology; the biology could be microbiology, biotechnology, nanobiotechnology and other), in graduation, post graduation and doctoral degree. During post graduation and doctoral degree, you have to include some aspects of marine sciences in your research. This will definitely help you to get selection in oceanography.

Good Luck....
