Does anyone know how to get to San Diego Sea World If you are taking a Metro link Train to Oceanside?

I am thinking about taking the Metro link train to Oceanside. From Oceanside train station to San Diego Sea World. Does anyone know which buses or public transportation that takes you to Sea World from Oceanside Train Station. I can't take the Amtrak due to time restraints and Metro Link does travel in the early morning on the weekdays. I am from Orange County area.
