There are no new questions. Have a research question? Trust me, it’s been asked before. Put your exact question into quotations as a search term, and you will find, at the very least, a lead to your answer. Want to find out how much of the ocean has been explored? Type “How much of the ocean has been explored” into your search engine, and you will likely get your answer.
