Any Teen Jobs Ideas Marine Biology Related?

Hi, I am 17, and currently work at recreation center. I would like to go to college for Marine Biology and have a career on it and would like to look in to finding a new job that would give me a better shot at getting into a good marine bio program, and give me more experience/knowledge for the future. I don't have any aquariums near because im in AZ. I thought of possibly a petstore but I was trying to brainstorm something more creative.
