Not called the ‘Blue Planet’ for nothing – the surface of the Earth is largely covered by water. Land – the bit we live on – only represents about 30%, and the oceans contain more than 96% of all the water on Earth.


The biggest living mammal known to man – the Blue Whale – and some of the smallest organisms (plankton) live in the oceans.

Despite our technological advances, we still know almost nothing about the deepest parts of our watery planet. Largely because it is an alien environment that man cannot easily explore.

We can dive with body mounted equipment with relative ease and safety down to about 50 m. Using specially designed underwater vehicles we can send equipment and cameras down a long way.

But it’s so cold and dark, and the pressure so incredibly high (it would squash a nuclear submarine flat), that man will not get to the bottom in the foreseeable future.

The deepest part of the ocean is called the Challenger Deep, in the Pacific Ocean at the end of the Marianas Trench. At over 36,200 feet (11,128 metres) it could swallow our highest mountain (Everest) with more than a mile (7171 feet/2,206 m) to the surface left above it.

Marine biology is concerned with the study of all the flora and fauna that lives in this incredibly diverse but hostile environment. You will learn about the various “zones” and how they affect all aspects of our lives. The weather is the biggest influence on where we live and how we survive – it’s driven almost entirely by what happens in the ocean.

If you want to really understand the biggest and least controllable influence on the human race, this course is a great place to start. Enrol today.

Who is this course for?

If you're fascinated by the sea and the life in it, this course will give you a great grounding in the ocean environment. The sea is the last great unexplored environment on planet Earth, and we still don't fully understand it. Explore from the safety of your lounge, office or bedroom. Gain some real knowledge without getting wet.

What does study method mean?

Study method describes the format in which the course will be delivered. At courses are delivered in a number of ways, including online courses, where the course content can be accessed online remotely, and classroom courses, where courses are delivered in person at a classroom venue.

What are CPD hours/points?

CPD stands for Continuing Professional Development. If you work in certain professions or for certain companies, your employer may require you to complete a number of CPD hours or points, per year. You can find a range of CPD courses on, many of which can be completed online.

What is a ‘regulated qualification’?

A regulated qualification is delivered by a learning institution which is regulated by a government body. In England, the government body which regulates courses is Ofqual. Ofqual regulated qualifications sit on the Regulated Qualifications Framework (RQF), which can help students understand how different qualifications in different fields compare to each other. The framework also helps students to understand what qualifications they need to progress towards a higher learning goal, such as a university degree or equivalent higher education award.

What is an ‘endorsed’ course?

An endorsed course is a skills based course which has been checked over and approved by an independent awarding body. Endorsed courses are not regulated so do not result in a qualification - however, the student can usually purchase a certificate showing the awarding body’s logo if they wish. Certain awarding bodies - such as ABC Awards and TQUK - have developed endorsement schemes as a way to help students select the best skills based courses for them.
