Oceanography: The reason why I'm taking Marine Science/Oceanography is because I want to learn everything or some of what Oceanography is all about and learn about the animals in the ocean as well (mammals). I'm also trying to know the basics of marine science and what do marine scientists do when they study marine science in the ocean. What do they find, what experiments do they do to find the answer's they are looking for. What steps do they take and what chemical they use during the experiment.
