Marine biology is a branch of science that deals with the study of marine life and the organisms found in the sea. It can also include the study of the ocean itself as well as human relations with the marine world. It is a very broad field and requires a lot of efforts from the very beginning. This article discusses the role of a marine biologist, necessary qualifications and basic requirements to be a marine biologist, basic facts about the field, best colleges for studying and inputs from some famous marine biologists of the world.

The Role Of A Marine Biologist

The job of a marine biologist includes studying the organisms and to observe, manage and protect them. They may also have to write reports based on their research or as their projects demand. There are many titles and specializations in the field of marine biology, but all of them are concerned with the study of marine organisms.

Marine biologists may be working on ships, beaches or even alt marches for their research. They may also be required to work in a scientific laboratory to observe and conduct researches about microorganisms found in the oceans.

Marine biology may also involve scuba diving for collecting specimens or for studying large sea animals like sharks and whales. Biologists may also be required to study other parts of the ocean like coral reefs and to study the patterns in the increase or decrease in the population of marine life.

Zoos and aquariums also require marine biologists to take care of the marine animals and to make sure that their environments are suitable for them to thrive and stay healthy.

Another important field that a marine biologist may be concerned with is the protection of the marine environment. A marine biologist may need to record, observe and study the concentration of toxic chemical substances present in water bodies and about what impact they have on marine life.

A marine biologist may also work as a teacher (professor) in colleges and universities if he or she is not interested in traveling a lot in doing fieldwork. Another option for the same may be working as a consultant or an advisor for the government or for a private firm.

Most of the times, the job of a marine biologist involves working in a team of scientists and engineers for their research or projects.

Necessary Qualifications For Becoming A Marine Biologist

There are a lot of criteria that a person may need to meet for becoming a marine biologist. The career requires the candidate to have subjects such a physics, chemistry, biology as well as mathematics in the undergraduate level or in India, at a 10+2 level. A degree in marine biology is a must. Pursuing courses in a field like engineering or computer science is also recommended for additional knowledge for ease in the career. The candidate should also have fluency in English in both written and spoken, as most of the work of a marine biologist requires working in a team, conducting researches and writing reports.

The subjects that marine biology aspirant may be cell biology, evolution, ecology, marine ecology, zoology, biochemistry, etc. Practical skills are given more importance than theoretical knowledge.

Bachelor’s degrees may help aspirants to find in a job in their desired field, but it is recommended that one should pursue higher education in the same as the field of marine biology does not provide with a good salary as some other jobs.

The Bachelor of Science in Marine Biology is a course of a three-year duration which is most commonly chosen by marine biology aspirants. One can also opt for a diploma of 6 months.

One can go for a master’s degree that specializes in this field or their subjects of interest which can include marine chemistry, economy, biostatistics, oceanography, geology or to specialize in a particular class of marine organisms such as mammals, fish, microorganisms and other wildlife. For a master’s degree, one can go for Master of Science in Marine Biology (2 years) or even for a Master of Philosophy (M.Phil.) in Marine Biology (2 years).

A candidate can also pursue a Ph.D. in order to further enhance his or her skills as a marine biologist. A Ph.D. has a duration of 3 years.

Some of the leading colleges offering such courses in India are as follows:

  • Karnataka University, Karnataka
  • Cochin University of Science and Technology, Kerala
  • College of Science and Technology, Andhra Pradesh
  • Pondicherry University, Tamil Nadu
  • Annamalai University, Tamil Nadu
  • Andhra Pradesh University, Waltair
  • Veer Narmad South Gujarat University, Surat

With the advancement in science and technology, the scope in the field of marine biology has been increasing since the past 3-4 years.

Career Options In Marine Biology

Earlier, we listed some of the various fields that a marine biologist can opt for. This is a very broad field of study that offers people with many career options. The average salary of a marine biologist was roughly $50,000 per annum in the year 2018.  This is however dependent on various factors and cannot be considered as very accurate as there are a lot of different types of jobs that one can opt for here. Following are some of the many jobs that you can do as a marine biologist:

1) Research

This is the most widely chosen field in marine biology. Research in itself can offer many career paths. In this field, one can become a field scientist, a research technician, a fish biologist or even a professor. This field requires high qualifications like a master’s degree or a doctorate. Most people who want to enter the field of research opt for specializations in subjects like oceanography, biology or aquatic and fishery sciences. One can work for the government or a private firm in the field of research or even work independently or as a freelancer.

2) Education

Another important career path for a marine biologist, education can be a very rewarding option. In this field, one can choose to be an education specialist, education director, aquarist, or a marine science program coordinator. Teaching in schools, colleges and universities may also come under this category. One of the biggest advantages here is that the fieldwork is minimal to none. This is a perfect field for those who are interested in marine sciences but do not wish to or can not travel too much. The subjects that one might need to specialize in to be a part of this field are education, environmental studies. One may require a bachelor’s or a master’s degree in education along with a qualification in marine biology. If one wishes, he or she can also pursue a Ph.D. in the same.

3) Health Sciences

This is one of the most unique career options in the field of medicine. At the same time, this can be one of the hardest careers to pursue. This involves pursuing a medical degree and becoming an aquatic veterinarian.

The general duties of an aquatic veterinarian are to perform basic exams and evaluations of the animals, giving them vaccinations on time, taking blood samples and other fluids coma prescribing medicines, observing and evaluating the behavior, performing surgeries if necessary, treating wounds, taking X-rays and supervising veterinary technicians.
Aquatic veterinarians are required in aquariums, zoos, museums, and Marine parks.

They are also required by marine mammal trainers and other marine biologists.
A job as a biomedical researcher can also be taken up. Anyone wanting to pursue this needs to get a bachelor’s degree in biology, chemistry or biochemistry. For veterinarians, a medical degree is compulsory. Although most firms and organizations employ people with a bachelor’s degree, it is recommended that on pursues a master’s degree or a doctorate.
