Introduction

The study of marine creatures, their behaviour, and interactions with the environment is known as marine biology. Marine biologists are scientists that study creatures that live in the sea or in salt water. Some marine biologists research the behaviours and habitats of marine plant life or microscopic creatures, while others work with marine animals such as fish and whales. Marine biologists differ not just in the creatures they examine, but also in how they carry out their research. Some work in the field doing observation or preservation efforts, while others work in research laboratories, while still others engage in both.

Marine biologists also do study in the areas of marine ecology, conservation, and understanding the evolution, behaviour, and physiology of marine organisms. The physiology, ecology, distribution, life cycle, illnesses, and migration of ocean creatures are studied by marine biologists. He’ll also look at the ramifications of pollution. A good marine biologist will be an expert in the categorization of sea life and will be able to identify how closely two species are linked and where they belong in the ocean. This ability will also enable him to effectively oversee sea-farming operations. Because a degree in marine biology allows a person to learn about the entire marine fauna and flora, obtaining a degree in the field necessitates a great deal of perseverance and dedication in order to not only obtain the necessary qualifications, but also to emerge as a professional and dedicated marine biologist.

Nature of work

The duties of a marine biologist are similar to those of any biologist and generally require the ability to do the following work:

  • Study marine life in natural or controlled environments
  • Collect data and specimens
  • Study species characteristics
  • Assess human influence
  • Use technology to track and measure creatures
  • Analyse the health of various components within the ocean environment
  • Work to repair damaged ecosystems
  • Using instrumentation to track and measure organisms
  • Using computer modelling to build predictive data
  • Consulting for programs that aim to monitor pollution
  • Monitor and manage populations
  • Report findings
  • Teach and supervise students

How to become a marine biologist

Marine biologists, like other scientists, pursue a rigorous education that includes both undergraduate and graduate studies. Most aspiring marine biologists study biology or zoology as undergraduates, with others opting for marine biology as a major. In addition to obtaining a natural sciences education, marine biologists may find it beneficial to have a solid foundation in engineering, mathematics, or computer science. Marine science master’s degree programmes emphasise research and advanced study. Biostatistics, oceanography, marine chemistry, ecosystems, and geology are among the subjects offered to students. Graduate students are also required to do original research and write a thesis in their field of study. A PhD is required for marine biologists who want to perform independent research.
