The study of marine biology includes a good sort of disciplines like astronomy, cellular biology , biological oceanography, chemistry, biology ,ecology, geology, meteorology, physical oceanography and zoology and therefore the new science of marine conservation biology draws on many longstanding scientific disciplines like marine ecology, bio geography, zoology, botany, genetics, fisheries biology, anthropology, economics and law.
Like all scientific disciplines, the study of marine biology also follows the methodology. The overriding goal in all of science is to find the truth. Although following the scientific method is not by any means a rigid process, research is usually conducted systematically and logically to narrow the inevitable margin of error that exists in any scientific study, and to avoid the maximum amount bias on behalf of the researcher as possible. 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.
