Oceanography and Marine Biology Overview

Marine biology studies the organisms that inhabit the sea, their interrelationships, and their interactions with their environment.

Basic knowledge of marine biology is necessary to understand how marine organisms relate to us and the marine environment.

Oceanography studies the oceans and their phenomena, such as waves, currents, and tides.

<p>The difference between oceanography and marine biology is pretty clear. Marine biology studies the physical elements of the ocean. Whereas, in the ocean, there are two areas of study that are not entirely distinct, and they frequently overlap. Therefore, combining elements from both fields is necessary to form a complete picture of the ocean and its inhabitants.</p> Signup and view all the answers
