The power of an Oceanographer comes in the ability – nay, the responsibility – to add to the overall knowledge of humanity. Sure, you may be using your scientist skills to locate potential sites for extracting petroleum. But you may also be working to protect the earth and its natural resources. The ocean is a very important part of our planet.
You know what they say - knowledge is power. Therefore, if your job exists solely (fish pun!) to add to that bank of knowledge, being an Oceanographer is a pretty powerful position. Use that power wisely, grasshopper.
