Description
The International A Level Marine Science course will provide you with a broad overview to marine biology. You will learn the science behind water including particle theory, bonding, solubility in water, density and pressure. You will also learn about the earth including tectonic processes, weathering, erosion, tides and currents.
Other chapters will cover marine ecosystems, classification and biodiversity along with physiology of marine organisms.
The course touches on parts of Chemistry, Biology and Geography and these stimulate an introduction to the science of the marine environment.
Progression
Marine Science provides exciting opportunities for learners who want to progress onto a Marine Biology Degree at university.
Once learners have gained a degree in this field or something similar, they can seek employment in marine research institutions, universities, international organisations and government agencies.
Courses that will compliment Marine Science include A Level Biology, Chemistry and Geography.

Cambridge International Examinations (CIE)
This A’ Level Marine Science Course will provide a coherent and stimulating introduction to the science of the marine environment. The content of the AS part of the course concentrates on the scientific study of the sea and its ecosystems, while the Cambridge International A Level part of the course concentrates on human activities that depend on the sea and have an impact on it.
The course will foster creative thinking and problem-solving skills, which are transferable to any future career path.
How will I benefit from the International A Level Marine Science Cambridge course?
The aims of this course are to enable learners to:
- acquire knowledge and understanding and develop practical skills, including efficient, accurate and safe scientific practices
- learn to apply the scientific method, while developing an awareness of the limitations of scientific theories and models
- develop skills in data analysis, evaluation and drawing conclusions, cultivating attitudes relevant to science such as objectivity, honesty, enquiry and inventiveness
- develop effective scientific communication skills, using appropriate terminology and scientific conventions
- understand their responsibility to others / society and to care for the environment
- enjoy science and develop an informed interest in the subject that may lead to further study.
Key Concepts
The key concepts for Cambridge International AS & A Level Marine Science are:
Observation and experiment
The scientific process of observation and enquiry, experimentation and fieldwork are fundamental to marine science.
The science of water
Water is the key component of the oceans and an understanding of water at a molecular level underpins concepts such as salinity, pressure, density and the availability of key gases and nutrients, which in turn affect the distribution and abundance of living organisms.
Forming and shaping the ocean floor and coastlines
Dynamic interactions between the lithosphere, atmosphere and hydrosphere lead to the development of diverse marine habitats, which are subject to ongoing changes.
Organisms in their environment
The marine biome is the largest biome on the planet and contains many diverse habitats, within which organisms interact with the biotic and abiotic environment. The morphology, physiology and behaviour of organisms are adapted to niches within these habitats. By understanding this diversity, students will have a greater appreciation of the marine environment and the need for its conservation.
Human influences in local and global contexts
Human activities may have a local and global impact. The exploitation of marine resources and the disposal of waste in and around our oceans must be managed if our use of the oceans is to be sustainable for future generations.

Cambridge Assessment
There are three routes learners can take when completing exams for the Marine Science course with Cambridge
- AS Level Qualification only – Learners take all AS exam papers (Paper 1 & Paper 2) in one exam sitting.
- Full A Level over 2 years – At the end of year 1, learners take all AS exam papers (Paper 1 & Paper 2) in one exam sitting. In a separate exam sitting at the end of year 2, learners then take all A2 papers (Paper 3 & Paper 4). If learners achieve a pass in all four papers, they will be awarded their Full A Level in Marine Science.
- Full A Level – Learners take all papers for AS and A2 in one sitting (Paper 1, Paper 2, Paper 3 & Paper 4).
