As with oceanic-continental convergence, when two oceanic plates converge, one is usually subducted under the other, and in the process a trench is formed. The Marianas Trench (paralleling the Mariana Islands), for example, marks where the fast-moving Pacific Plate converges against the slower moving Philippine Plate.
A bachelor's or master's degree is typically required for entry-level marine biology research jobs, such as those at private research organizations and biotechnology companies. Doctoral degrees are usually required for faculty positions and other jobs that allow you to follow your own research interests.
Marine scientists are required to have at least a bachelor's degree in marine biology, marine science or a closely-related field. After completing core requirements in biology, chemistry and physics, students delve into specialized topics such as aquatic animal biology, oceanography and toxicology.
