Career as an Oceanographer or Marine Biologist


A person who studies the aspects of the oceans is known as Oceanographer. Oceanographers are the scientist who studies the ocean. The work of an Oceanographer requires the scientific knowledge of biology, chemistry, physics, geology, geophysics, mathematics and engineering science. This emerging field gives the opportunity to gain scientific knowledge as well employment in various public and private organizations.

Oceanography is the branch of Earth Science which deals with the study of oceans and seas with specific importance to coastline, estuaries, coastal waters, shelves and the ocean bed. The subject of study covers 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.

Marine Biotechnology, one of the possible specializations, involves developing and testing new drug treatments and protocols that are derived from ocean life. Another specialization is molecular biology, which is helpful in identifying microorganisms as well as diagnosing diseases that are caused by microorganisms.

Work Environment

Oceanography centres, laboratories, aquariums, research boats and vessels are some of the possibilities for field workplaces. It would not be unusual to find a marine biology graduate working in a tide pool, a swamp, a mangrove forest, a coral reef, or any place on earth that supports marine life. Travel to interesting places is one of the possible perks for a career in marine biology. Some of the possible careers for a marine biology graduate would include teaching at a high school or college level, being a research scientist, an oceanographic laboratory technician, working for an aquarium or zoo, or any number of possibilities for consulting with different government agencies and universities.
