Marine biologists research, analyze and conduct experiments on oceans, seas and their life forms. The field of marine biology focuses on the study of animals and plants that reside in saltwater. Due to the vastness of Earth’s oceans and seas, the job description associated with a marine biologist is wide-ranging.
In addition to studying saltwater plants and animals, marine biologists also study the sea and its interaction with coastal areas, sea floors and the atmosphere. Marine biologists use this information to evaluate environmental policy and forecast changes to the earth’s infrastructure and climate.
Marine science is an expansive field. The science covers several subjects, including zoology, ocean modeling, hydrographic surveying, ecosystem dynamics, geology, coastal processes and biogeochemistry.
Marine biologists work in offices, laboratories or out in the field. The duties of a marine biologist include collecting samples and analyzing data as it relates it to the oceans and seas. Marine biologists prepare reports for governing bodies, commercial companies and agencies. They also work with technology, tagging animals for population assessments and general analysis.
Other job descriptions include evaluating damage to coral reefs, measuring the effectiveness of environmental regulations, studying the impact of water pollution and fishing on marine environments, and offering advice on climate change, sea-based technologies, and other environmental impacts.
Marine biologists work for universities, international organizations, government agencies, non-profit organizations, marine research institutes and commercial companies. Although knowledge in all fields of marine science is desired, specialization in a specific area is often required for advancement in the field.
