A Selection Of Marine Biology Dissertation Ideas To Explore


Marine biology is a diverse topic and makes for interesting dissertation topic. At the same time marine biology is a vast subject and a generic paper will not be of much interest to average reader. If you want to impress your professor you will have to come up with something more specific and a topic that allows for more detailed research. You will have to select something that is unique and original. Without the right topic you cannot hope to make your paper stand out from the rest. Here are is a list of few topics to help you make up your mind.

The advantages of a proper idea

The world under the sea is vast and mighty. There are so many different creatures and different ecosystems. The creatures have evolved over thousands of years and even when science has made progress over so many years, many things still remain unexplored. There are creatures under the depths of the sea that have not been catalogued or there are different water chemistries which have not been explained. The dissertation is a valuable contribution to marine biology and hence you will have to work on something that has not been covered before.

List of ideas to work on:

  • The rarest mollusks found at the bottom of the sea.
  • What makes the mantis shrimp different from the other invertebrates?
  • Describing the process of coral formation and coral mating
  • The adaptability shown by lion fish and how it is endangering the ecosystem
  • How have the seas and oceans adapted to the growing levels of pollution.
  • The process of creating sea water at home for aquaria and how effective is it?
  • Can corals be harvested in a sustainable environment?
  • The best attribute of an octopus. How have they evolved over the centuries? Is it the most intelligent creature living in the sea?
  • How does marine biology draw parallel with the evolution of species?
  • Illustrate the part played by planktons in the marine ecosystem.
  • Describe the reason why marine fishes and invertebrates are so much more colorful?
  • Describe the reproduction process of moray eel
  • The various adaptations by the fishes living in the depths of the sea
  • Some of the creatures found at the very bottom of the sea and how have they adapted to the lack of sunlight?
  • Lifecycle of a fish, that migrates from the sea to freshwater for spawning. Give reason for the behavior.

The ocean covers the largest portion of our planet. It is home to different organisms that are studied by marine biology. It is very interesting field of study that can give us an insight into the basics of the life itself since it began in the ocean. Use the following list of ideas to develop a perfect topic for your dissertation.

  • The history of marine biology.
  • The first written records date back to 1200 BC when the first ocean voyages began. You can devote your dissertation to the early expeditions or the exploration of the deep sea and their impact on the studies.

  • The future of the science.
  • It is know that only 5% of the Sea has been studied. What is the next step in ocean exploration?

  • Famous scientists and explorers.
  • Who were those people who managed to bring wonders of the underwater world to ordinary people?

  • Global change.
  • How do temperature rising affect sea life? What should we expect in future?

  • Ocean pollution.
  • What is needed to be done to protect the ocean? Is sea pollution dangerous for humans?

  • Coral reefs.
  • How were coral reefs formed? Reefs as an ecosystem: How do different species cooperate with each other?

  • Whale migration.
  • Why does it happen? What are the types of these migrations?

  • Oil spills.
  • What are the environmental effects of oil spills? Recovery process: How long will it take?

  • Endangered marine species.
  • How can we protect threatened animals? How does pollution affect them?

  • Life on the deep ocean floor.
  • What are species that live on the sea bottom? What is their life in complete darkness under tremendous water pressure?

  • Marine mammals.
  • What are the biggest threats mammals face today?

  • Aquaculture.
  • Why is aquaculture important? Aquaculture activities around the globe: methods and prospects.

  • Ocean circulation.
  • Has global warming changed ocean currents? Why?

  • Coastal processes.
  • How do marine processes influence coastal environment?

  • Microscopic life in the Sea.
  • Is microscopic life important for the ocean ecosystem?

  • Freshwater ecosystem.
  • Does freshwater fauna extinct? How can we stop it?

  • Aquatic toxicology.
  • What is the role of aquatic toxicology in America? What is the effect of the toxicity testing?

  • Marine resources.
  • We continue exhausting the ocean environment to satisfy our needs. Can it ever recover from such a pressure?

  • Dolphin echolocation.
  • Can they actually see using echolocation?

  • Dead zones.
  • Why do dead zones spread? What measures are in place to prevent their spread?
