Marine Biology, What you need to know.

Water is a very critical part of existence, the Earth and the human body are made up of more than 59% of water. Marine biology is the study of marine life, whose behavior and interaction with the environment expose our society’s ability to produce food, water and shelter as we continue to focus on the ocean to help sustain our basic needs.

Water on Earth

71 percent of the Earth is water

A large part of all life on Earth lives in the ocean. The exact size of this large proportion is unknown, as many marine species have yet to be discovered. The ocean is a complex three-dimensional world that covers about 71%of the Earth’s surface.

Percentage of water in the body

Up to 60 percent of the human body is made up of water

This makes marine biology very extensive, so most researchers choose a specific area of interest and focus on it. Specialization can be based on a particular species, population, behavior, technology, or ecosystem.

Molecular biology is a related field of expertise in marine biology. The researchers applied molecular techniques to many environments, from coastal swamps to the deep sea, as well as a variety of organisms such as viruses, plants and fish.

 

Why is Marine Biology Important?

Marine biologists study biological oceanography and related fields of chemical, physical and geological oceanography to understand marine life.  

Advances in technology, coupled with demand, will increase our ability to access food, drinking water, energy, waste disposal and transport from the ocean.

This generation and future generations must build on our existing knowledge of the oceans and their potential to help meet the needs of the world and its inhabitants 

What does a Marine Biologist do?

Marine biologists study the ocean and its creatures. They protect, observe or manage marine life or animals, plants and microorganisms.

They observe and study the animals and plants that inhabit the ocean. Marine biologists can have many specialized fields, each with its own title. However, typical tasks include studying marine life, collecting biological samples, analyzing specimens or data, and writing reports.

Most use instruments or technical equipment to copy, document, model, or monitor their research. In zoos or aquariums, they take care of the life of marine animals and observe their reactions to the environment and their behavior patterns, they can also study larger marine animals such as sharks, whales, seals or other sea they assess the marine animals need to make sure they are healthy and thriving.

Some marine biologists may specialize in the complex chemical composition of marine toxins and their impact on the environment, or how weather affects marine life. These marine biologists usually work with other scientists, engineers, technicians, or environmental agencies.

They will consult and work to rebuild damaged marine ecosystems, advocate or help comply with environmental regulations, or help fisheries management or the coast guard.

Some marine biologists can also conduct research and research in the laboratory to observe and record animals in tanks or view tiny creatures under a microscope.

How to Become a Marine Biologist

Becoming a marine biologist may be competitive, but gaining hands-on experience before graduation may help.

To become a marine biologist, you need to have at least a bachelor’s degree. However, many employers want applicants to have a master’s degree specializing in marine biology and aquatic research, and it is becoming increasingly common for employers to want candidates to have a doctorate.

Many universities and colleges offer courses in marine biology; however, degrees in biology, zoology, fisheries, ecology, or other animal sciences are common. Courses usually include courses in Biology, Chemistry, Physics, Mathematics and statistics. In addition, training in legal and public policy is possible.
