Oceanographic Essay On Marine Science

Introduction: Marine Science

The oceans are part of the thin, outer shell of the Earth and marine science is the study of this envelope, from the deep sea to shallow coastal oceans: their biology, chemistry, geology and physics together make marine science a richly inter-disciplinary science. The oceans are dynamic and vast, they contain most of the Earth 's water and carbon and surface heat, and much of its biomass, but they do not operate alone. In collaboration with the atmosphere, continents and ice (cryosphere), they form a working machine, driven mostly by energy derived from the sun and the Earth’s interior and other substances found in space (Garrison, 2013).

Marine Scientists focus their work on both practical or applied problems and

Oceanographic research requires multi-disciplinary team effort: a typical project employs scientists recruited from most of the major scientific disciplines, and involves problems that do not fit easily within the confines of the narrow, compartmentalized view of science (Gross, 1972).

Four branches of Oceanography

The world ocean is too vast for a single person to be an expert on all aspects, even after a lifetime of study and work; it is only because the study of the ocean requires the application of a wide variety of scientific disciplines (Gross, 1972), therefore oceanography is divided into four major branches: Biological, Geological, Physical and Chemical (Garrison, 2013).

Biological Oceanography focuses on the basic observations on the biology of marine organisms and their environments and that is the important aspect of biological oceanography (Lalli & Parsonns, 1997). The ocean sustains an astonishing variety of living creatures, diverse in both physical form and life style and that is the reason why expects in zoologists, microbiologists and fisheries have been attracted to oceanography as a result of their interest in plant and animal life in the ocean(Gross,
