Marine Biology Diploma
Level 3 (Advanced)

Marine Biology course is the study of marine organisms, their behaviours and interactions with the environment. 

This 6 module Marine course has been specifically designed for those interested in working or volunteering in the many different  areas of marine biology.

The course explores the ocean as a habitat and the fascinating diversity of animals that live in the marine environment. 

Gain an understanding of oceanography as well as the important areas of the sea such as tropical coral reefs, mangroves, the polar regions, shores, estuaries and the deep sea. 

This course also investigates the threats that impact the oceans and how we can preserve the ocean as an important habitat.

Anyone 18 or over and studying our Marine Biology Diploma Course is eligible for ZSL (Zoological Society of London) Fellowship.

Module 1


Module 1 of this Marine Biology course explores the subject of Oceanography. Oceanography covers the structure of the oceans: how they are created and destroyed. It looks at how ocean topography varies from the shoreline and continental shelf to the ocean basin, abyssal plain and trenches. This module explores the ocean as a habitat and the chemistry and properties of seawater, including how light and sound are transmitted. Learn how waves are formed and how the major currents move around ocean basins.

Module 2

Coral Reefs

This module explores the tropical seas and how coral reefs are formed and distributed around the world. Learn how coral animals live and how they evolved to form complex ecosystems. Understand the symbiosis between coral animals and plants that enable each to live and support an amazing diversity of other species in an otherwise barren part of the ocean.

Module 3

Mangroves and Seagrass Beds

This module explores the fringes of tropical seas where they form a unique habitat for marine animals. Mangroves are important nursery areas for fish such as lemon sharks and they form a buffer between the land and the open ocean. Many species live in mangroves permanently and they are important food sources for residents and visitors alike.

Module 4

The Polar Regions

This module explores the polar seas and the important differences between the Arctic and Antarctic regions. Learn about the amazing adaptations to the animals that live in such extreme environments and how they are able to live in sub-zero temperatures. Explore some of the enigmatic marine animals of the polar regions such as polar bears in the Arctic and penguins in the Antarctic.


Module 5

Shores and Estuaries

Although a smaller number of species appear in this group they are some of the more fascinating to study.

Module 6

The Deep Sea

The deep sea is a fascinating place that we still know little about. Learn about the strange animals that are adapted to living in the deep sea and how they cope with extreme cold, continuous darkness and intense pressure. We look at how energy is transferred to the deep ocean and how it supports life in the abyss.

2 Week Practical Placement (Optional) at the Merlin Animal Welfare and Development Department in Weymouth OR the Blue Planet Aquarium in Cheshire

Merlin Animal Welfare and Development department in Weymouth

The Merlin Animal Welfare and Development department supports SEA LIFE public aquaria throughout the Merlin estate and is responsible for setting standards, the development of new displays and rolling out new concepts to SEA LIFE sites. The department is located on the same site as Weymouth SEA LIFE Park but is run separately. The Department offers site support for all sites globally, and undertakes research into all aspects of exhibitory. Their main concerns and areas of expertise are animal health and welfare and they advise all sites on these matters. 

This placement gives students the opportunity to work alongside experienced aquarists and marine biologists in the day to day running of the Concept Development Unit where animals are quarantined and their husbandry requirements developed ready for innovative displays. Students attending this placement will gain hands-on experience working with a variety of marine animals.

This is a fantastic opportunity to gain highly sought after hands-on experience. This placement includes gaining skills and knowledge in:

  • Aquatic animal husbandry
  • Species identification
  • Veterinary care
  • Animal behaviour
  • Life support systems
  • Water quality

The animals at the Merlin Animal Welfare and Development department will vary but will predominantly include marine fish and invertebrates.

The Blue Planet Aquarium in Cheshire

Offers the placement working with a wide range of species. Their zoological collection is split into three subsections:

  • Freshwater
  • Marine
  • Herpetological (the section also contains Asian short clawed otters)

The main objectives of this programme are to learn about the working world of a public aquarium and the aquarium industry as a whole. As one of the largest commercial aquariums in the country the zoological department is proactive in conducting their own husbandry work, undertaking the volunteer programme you will benefit from learning about and or having an influence on:

  • Exhibit development
  • The different biomes Blue Planet Aquarium creates
  • The role of SCUBA diving in the aquarium
  • Health and safety practices within a zoological/aquarium setting
  • The role of a public aquarium in modern day society
  • Animal husbandry
  • Zoological collection management

Having a placement is NOT a compulsory element of this course and we recognise that some students may not be able to commit to either placement. Accommodation and travel costs are not included.

Please note that students can enrol on this course without the Practical Placement. Students must be at least 18 years old to take part in either placement.
