Marine biology is the study of life in the oceans and other saltwater environments such as estuaries and wetlands. All plant and animal life forms are included from the microscopic Picoplankton all the way to the majestic blue whale, the largest creature in the sea—and for that matter in the world.
Marine biology consists of a multiple subjects such as astronomy, biological oceanography, cellular biology, chemistry, ecology, geology, meteorology, molecular biology, physical oceanography and zoology plus new science of marine conservation biology draws on many longstanding scientific faculties like marine ecology, bio geography, zoology, botany, genetics, fisheries biology, anthropology, economics and law.
The primary component of scientific research is characterization by observations. Hypotheses are then formulated and then tested based on a number of observations in order to determine the degree to which the hypothesis is a true statement and whether or not it can be accepted or rejected. Testing is then often done by experiments if hypotheses can produce predictions based on the initial observations.
The essential elements of the scientific method are iterations and recursions of the following four steps:---->
Hypothesis (a theoretical, hypothetical explanation)
Prediction (logical deduction from the hypothesis)
Experiment (test of all of the above)
These steps are all used in the study of marine biology, which includes following main sub fields:
Microbiology, Fisheries & Aquaculture, Environmental Marine Biology, Deep Sea – Ecology, Ichthyology, Marine Mammology & Marine Ethology.
One of the best places to study this course is Great Barrier Reef (G.B.R) in Australia. RMIT University in Australia offers this course to students at G.B.R. RMIT is one of the few leading University in the World for Marine – Biology course and many other UG / Pg & Master courses in numerous fields for Local and International course.
