Marine Biology

(14 customer reviews)



Marine Biology Diploma

Marine biology is the study of living organisms in predominantly saline bodies of water, especially the ocean. Marine biology is different from marine ecology as the latter revolves around the interaction of organisms between themselves and the environment whereas the former focuses on the study of organisms themselves. A large percentage of all life forms on our planet survive in the ocean. The enormity of the oceanic population is still not well documented as there are many species in the ocean yet to be discovered. The ocean is a three-dimensional water body covering around 71% of the earth’s entire surface.

Marine life is a notable resource giving food, medicine and raw materials along with enhancement and support of tourism and other recreational activities all around the globe. Looking at the basic level it is not hard to understand that marine life plays a major role in determining the very nature of our planet. Marine organisms contribute greatly to the oxygen cycle and are very important in keeping the earth’s climate regulated. Shorelines are partially affected and in a way protected by marine life forms. Certain marine organisms even play a part in creating new lands. Many marine species are of importance to humans economically and this mainly includes food fish, be it finfish or shellfish. It is now known that the well-being of marine organisms and other organisms are closely linked and that too at an elementary level.

The course Marine Biology is of relevance today because the human body of knowledge regarding marine life and important natural cycles is rapidly growing. These cycles include those of matter like the carbon cycle, those of air like earth’s respiratory cycle and the movement of energy between ecosystems including the ocean. New discoveries are being made every day and yet large marine areas still remain greatly unexplored.

    Loved this course. As a Scuba Diving Instructor this helps me understand more about the oceans and what lives where.

    Diploma in Marine Biology is very useful, and very helpful for those who don’t have the resources (the funds, the schedule, or the right location) to attend classes in person.

    Very interesting course. I have always had an interest in the marine world but never had the time. Now seemed the prefect opportunity. So glad I did. Watched episodes of Blue Planet (there is also other BBC programmes which were useful to me) whilst doing the course to help with some of the concepts. Overall very good. Recommended

    A very good course with a good range of topics. The unit end tests were a good way of making sure one understood the information. This is a good introductory course.

    It’s a good course, although repetitive in places. Also some one the questions in the tests are dodgy, either not worded right, or my favourite where I answered right by selecting answer a but was wrong because there was an option that said “only answer a” which doesn’t make sense but hey! Killed 6 days.

    Useful and insightful course. Well structured covering this fascinating environment, and one we are learning more about every day. Useful for anyone who has an interest in the sea, the environment or ecology, and how our lives on land influence marine life. Recommended.
