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.
Most aspiring marine biologists complete a degree program in marine biology or a related science field, and seek out training or internship opportunities to prepare for the field. The term 'marine biologist' is often used indiscriminately for jobs that apply to the scientific observation and study of marine life.
