Marine biology is a learning and research field, and many marine biologists therefore work in coordination with universities and other educational institutions. In fact, many marine biologists are also teachers and professors during the winter months, when less work is being done in the field. Research projects are at the heart of what most marine biologists do, whether it be actually collecting specimens in the field, compiling research data, finding real life applications for the research data, or classroom teaching.
Some of the possible careers for a marine biology graduate would include teaching at a high school or college level, research scientist, oceanographic laboratory technician, working for an aquarium or zoo, and any number of possibilities for consulting with different government agencies and universities. Another potential career for a marine biology graduate would be hydrology, which is a scientist or researcher that studies bodies of water, and helps to find ways to eliminate water pollution. There are actually many environmental careers that can be attained with a degree in marine biology. Even a Fish and Game Warden, which is something akin to an environmental police officer, is a possible career move for a marine biology graduate.
