Without any additional information I don't think anyone can tell you if any career choice is right for you. My advise is to find out everything you can about marine biology. What schools excel in this program and what are the qualifications. I'd also have a plan B just in case things don't work out. When it comes to life decisions, and picking a career is certainly a decision that effects your entire life, don't let anyone else make it for you.
