What is Marine Science? The study of marine life and organisms in the ocean, marine sciences involve biological and physical sciences. While there are many different paths a Marine Scientist can take, get started by learning more from Greg Rouse, a Marine Biologist about their work and research from this video.

It is a wide and rich discipline, equally concerned with fish, plankton, whales, and sharks (marine biology) as it is with the chemical composition of ocean water (marine chemistry), the solid rock and basins that contain the oceans (marine geology), and the exploration of the oceans using quantitative interpretations of gravity and magnetics (marine geophysics).

Marine science commonly is called oceanography. As these names may reveal, this branch of science deals with study of oceans. Professionals in this field often are called marine scientists or oceanographers, but they also may take titles that refer to their specialties.

The ocean plays a central role in physical, biological, chemical, and geological processes on Earth. The field of marine science thus requires an understanding of the interactions between the biosphere, hydrosphere, lithosphere, and atmosphere.
