Marine biology is in fact an interdisciplinary field that deals with different aquatic environments in the seas and oceans, and due to the physical and chemical properties of these environments, the knowledge of biology with the help of other sciences to study the characteristics of biology. These environments address the characteristics of marine life, their relationship to each other, and their relationship to environmental factors.
In simpler terms, the biology of the sea was created in the world of science to study the living world in the seas and oceans.
Duties of a Marine Biologist
A marine biologist does things that not only benefit the present generation but also benefit future generations. Marine biologists study the marine ecosystem, which includes seas and oceans and some saline areas such as estuaries. They are also collecting sponges and looking for biologically active drugs. The work of a marine biologist involves counting and classifying marine species.
Marine biology is a discipline the breadth and depth of the sea
Marine biology discusses the observation and conservation of plants, coral islands, algae and marine organisms, and dozens of other diverse scientific activities. This profession is very challenging and valuable. The underwater world is a very strange and wonderful world. A world where the largest animal on Earth, the whale, lives. Which weighs 15 tons and is 27 meters long. Also, the most dangerous, intelligent, beautiful and harmless animals on Earth are present in this mysterious environment.
Trends in Marine Biology
• Sea animals: studies the structure of sea creatures, their types and their way of life.
• Ecology of the sea: identifies aquatic organisms, including plants and animals. For example, the; Habitat, possible changes in the living environment (changes including more or less marine life)
• Seaweeds: Seaweeds include: algae, aquatic shrubs, in other words the habitat, how they grow and reproduce.
• Pollution of the sea: Measures pollutants in water which are: nitrate (), nitrogen (), lead () as well as minerals; In other words, measuring the level of sea pollution and its effects on the living environment of aquatic organisms.
Duties of Marine Biologists
In general, the work of a marine biologist involves counting and classifying marine species. He studies, observes, theorizes the environmental impact of industrial processes, and also predicts the state of equilibrium of fish when fishing is declining.
The work of a marine biologist also includes research into how humans benefit from marine species, discovering different ways to obtain biofuels from algae, studying their ability to change sex, and how oil spills can harm marine organisms.
