Oceanography is the study of the ocean's physical, chemical, and biological characteristics, as well as the ocean's ancient history, current state, and future. The function of oceanographers may be more vital now than it has ever been, as the ocean is endangered by climate change and pollution, coasts are crumbling, and entire species of marine life are on the verge of extinction. Biological oceanography is, in fact, one of the most important branches of oceanography today. It is the study of the plants and animals that live in the ocean, as well as their interactions with the marine environment. However, oceanography includes more than just research and study.
