Industries & Professions /
There are more marine biologists than there are top positions at present. Changes in the earth's environment, such as global climate change and increased levels of heavy metals in the global water cycle, will most likely prompt more research and result in slightly more jobs in different subfields. Education is extremely important in this field. Most marine biologists in basic research positions have a Ph.D. Those with just a bachelor's or master's degree often work as science or engineering technicians, high school biology teachers, and in nonscientist positions related to biology such as marketing, sales, publishing, and research management.
