What is Marine Biology About?
Marine biology is not an independent science, on the contrary the science of biology most applied to the sea. Practically all the disciplines of biology are represented in marine biology. For example, there are marine biologists who study the basic chemistry of living elements. Others are interested in marine life as a set of organisms: how they act, where they live and why. Other biologists adopt a global perspective and look at how all oceans function as a system.
Marine biology is strongly related to oceanography, scientific study of the oceans. Within oceanography we can distinguish geological oceanography, studying the seabed, chemical oceanography, in practice study the chemical components of the oceans and physical oceanography, studying the waves, currents, tides and other physical aspects of the sea.
Anyway, marine biology is closely related to biological oceanography so much that it is impossible to separate them as disciplines. Sometimes we can separate them by saying that marine biologists tend to study organisms that live very close to the coast, while oceanographers focus more on life in the open sea, far from the coast. Another difference is that marine biologists study marine life from the perspective of marine organisms (studying how marine organisms produce organic matter), while oceanographers study it from the perspective of the ocean (studying the cycles of organic matter traverse the system) .
History of marine biology
Probably the man began to learn about marine life since he saw the sea. The knowledge of the ocean and its organisms expanded since man began to navigate the world known until then. An important aspect in the world of marine biology was verified in the nineteenth century, with one of the most important naturalists in history Charles Darwin who, in his journey on the Beagle, began to discover species that had not been known before and describe them in His notebook. I also explain the formations of the different coral rings, called atolls. I use nets to capture very tiny living beings, known as plankton.
Another very important expedition was the Challenger. A group of scientists in the nineteenth century, undertook a trip to study in concrete the oceans, instead of using the boats in another way. One of them was Forbes, who discovered many unknown organisms until then and recognized that life on the seabed varies according to the depths. It can be said that Forbes was the greatest marine biologist.
