You must be flexible. Being an oceanographer is a great career. It is truly exhilarating to discover things first-hand and explore questions whose answers will benefit our planet as a whole. As an oceanographer you may be an educator who has the privilege of passing along to others the experiences of your career and research. The minimum requirement for an oceanographer is a B.S. degree in ocean-ography, biology, earth or physical sciences, mathematics, or engineering.
Most jobs require graduate training in oceanography.
Take as many math, science, and computer classes in school as you can. Currently, the more math classes you take the better your job opportunities will be because you will be best prepared for a variety of jobs. Even if you do not understand why you're taking some classes or how they relate to your interests, take them anyway and do well. Generally, more math means a higher salary. Your college courses should include biology, meteorology, geophysics, and some specialized science classes that apply to the study of oceans.
