Marine biology is a diverse field that can offer many different job opportunities. For example, the marine biologist may study in marine protected areas, contribute to environmental management, assist in the growth and monitoring of marine species, or participate in academic research. Usually, marine biology jobs are available to people who have completed a bachelor's degree in science with an emphasis on marine biology at an accredited institution.
In general, marine biology is the study of organisms that inhabit the ocean or other marine environments. Since many types of species may live in or out of the water, the organisms that marine biologists study are not classified according to taxonomy, but rather by habitat. This can mean that marine biologists study anything from microscopic plankton to whales.
Since approximately 71 percent of the earth is covered by water, marine biologists may work in many different environments and locations. Depending upon the different marine biology jobs, some marine biologists may have a scuba-diving certificate, which gives them the proper training certification to work under water. Marine biologists also might work in marine labs, which are specially designed indoor facilities that provide habitat for marine species.
It can be common for marine biologists to be experts on a specific marine organism. For example, some marine biologists may be specialists in plant life, while others can be ichthyologists, meaning that they are experts in the study of fish. Some of the marine biology jobs that are available could correspond to the expertise of the marine biologist.
A fishery biologist is a type of marine biologist who may compile and analyze demographic statistics about fish. In these marine biology jobs, fish and shellfish usually are raised in a fishery marine lab, where marine biologists look for ways to help improve the health and lifespan of the fish. Fishery workers might look for strategies that help preserve exploited or endangered stocks of fish.
Protecting the marine environment can be another job for the marine biologist. These marine conservationists aim to sustain the ecosystem of marine environments, helping to secure a future for the organisms that inhabit them and promoting biodiversity. Marine conservationists can draw on traditional marine biology and other areas such as oceanography, genetics, and environmental management to envision projects intended to preserve the environment.
Some marine biologists may work in academics, as well. This can mean that they are an instructor at an institution teaching students about marine biology. They also may be involved in research projects that are being conducted at the school. Some academic marine biologists write textbooks on the subject or submit articles to peer-reviewed scientific journals about their research projects, helping to advance study in the field.
