15+ Research Ideas in Marine Biology for High School Students

As an ambitious high school student interested in marine biology looking to better your chances of getting into a prestigious program, you may consider different options — from internships to summer schools — to improve your knowledge. If this sounds like you, then consider undertaking a research project! Marine ecosystems are intrinsically linked to climate change and healthy oceans, as food, water, and shelter sources, are necessary to sustain life.  

Marine biology is a vast field with multiple avenues for research. Not to mention, undertaking an intensive research project helps build skills like critical thinking, problem-solving, and communication, and can go a long way in showcasing your demonstrated interest in a subject.  Research experience will add value to your college application as it shows that you’re intellectually curious and have a great aptitude for learning.

Ambitious high school students selected for the Lumiere Research Scholar Programs  work on a research area of their interest and receive 1-1 mentorship by top Ph.D. scholars .

Below are some marine biology research ideas for you to consider, some of which have been shared by our research mentors – we hope they inspire you!

Topic #1 - The Climate Crisis and its impact on marine biodiversity

Faced with climate change, our oceans are facing one of their most vulnerable moments in history. Understanding the intersection between climate change and marine biology is crucial to conserving and managing marine ecosystems. Global warming, ocean acidification, and deoxygenation — collectively known as the “deadly trio”  — are making oceans increasingly inhospitable to life and inhibiting the functioning of marine ecosystems. As a researcher, you could conduct critical investigations within this field and suggest more sustainable practices to preserve the marine ecosystem.  Depending on your research goals and how much time and resources you can commit, you could conduct either primary or secondary research.

Here are a few ideas you could choose from: 

1. Investigate how rising temperatures are affecting the migratory patterns of fish within a designated zone. Research where these species go and how the composition of marine communities affects interactions between species.

2. How does ocean acidification — when oceans absorb more carbon dioxide from the air — harm different kinds of marine species? What knock-on impact does acidification have on coastal communities that depend on the ocean for food and their livelihood?

3. Examine how corals are responding to climate change, how the change in oceanic temperatures affects their reef-building capabilities, and the knock-on effects.

4. Research changing ocean currents and circulation patterns and how they can impact the distribution of nutrients, affecting the productivity of marine ecosystems

5. Dive into the correlation and causation between extreme weather events and climate change. How does rising temperature affect the frequency and intensity of cyclones, hurricanes, and other natural disasters? 

Some of these ideas were contributed by Lumiere Mentors from the University of San Diego, California.

Topic #2 - Coastal economies and the marine ecosystem

Coastal economics and communities have a complex interaction with marine biodiversity, and their actions have both economic and ecological outcomes on the ocean . Marine and human health are closely connected — seafood is an integral part of coastal communities’ diet and marine-based products provide them with livelihood. As a researcher, you could investigate creating healthy marine socio-economic systems for the future,  and consider diving deeper into some of the following ideas: 

6. Review the effectiveness of different nations’ coastal zone management policies and how well they balance economic vs. ecological needs. You could then compile your findings into a best practices list and suggest improvements to existing policies

7. Make a valuation of the economic services of a designated coastal region. This can include a valuation of fishing activities, tourism, ocean-sourced products, etc, and their contribution to the economy

8. Examine how marine conservation and tourism can go hand-in-hand. Suggest ways to ensure the sustainable development of coastal economies

9. Explore innovative practices in sustainable seafood production and their economic implications for coastal communities

10. Suggest adaptation strategies for coastal communities facing frequent extreme weather events. What steps can be taken to protect their homes and their livelihoods?

11. Study how marine pollution impacts coastal areas, marine biodiversity, and communities’ livelihoods

Topic #3 - Exploring marine genomics

Marine genomics provides critical clues to understanding how life evolved underwater and how marine animals contribute to the ecosystem and create new chemicals and materials. Life has evolved from the ocean, and marine genomics has been used to study the short - and long-term effects of pollution on sea animals, their evolution, and genetic commonalities between fish in a particular region, to name a few. As a marine genome researcher, you could extract meaningful data about the origin and evolution of species and how they may adapt to changing environments. 

Here are a few research ideas related to marine genomics that you could consider:

12. Examine how environmental DNA is found in aquatic ecosystems. Here, you can learn about different molecular techniques and use them in marine or freshwater invasive species management. 

13. Study how human activity (pollution, fishing, habitat destruction) has impacted marine genomes and how other anthropogenic factors have influenced adaptation and genetic diversity in marine organisms.

14. Study the genome of an endangered marine species to understand what genetic factors contribute to its vulnerability. Suggest and develop conservation strategies. 

15. Examine aquatic species that survive in extreme climates (deep-sea vents, polar regions, etc). Study their genomes to understand what genetic features allow them to thrive in such conditions.

16. Undertake a comparative genomics study: choose two organisms from different marine families and compare the similarities and differences in their genomes. Research into how their genomic variations could be due to their habitat, adaptations, and specific behavior.

Some of these ideas were proposed by independent Lumiere Mentors.

Topic #4 - Ocean-based solutions for global challenges

The ocean can address some of the world’s most pressing challenges, from reducing emissions to producing clean energy, improving food security, and much more. Further, studies  show that ocean-based climate solutions can reduce greenhouse gas emissions by up to 35%. As a researcher, you could help contribute to critical research that can help limit pollution and create sustainable practices.

Some research ideas you can consider include:

17. Investigate how introducing artificial coastal reefs and other techniques to restore habitats can help improve marine biodiversity.

18. Study the effect of plastic pollution on marine life and examine the benefits of adopting more eco-friendly and biodegradable packaging materials. Develop new methods to remove plastic from the ocean.

19. Study carbon sequestration, the process of capturing and storing excess carbon dioxide. How can coastal ecosystems like mangroves, saltmarshes, seagrasses, etc. help mitigate C02 emissions?

20. Study more sustainable and effective practices for ocean farming.

21. Research different marine organisms that have a positive environmental impact (for example, seaweed helps remove toxins from the water and has a negative carbon footprint).

The ideas offered here are by no means exhaustive, and you could come up with your own research interests once you’ve dug deeper into a topic that interests you!

Core Research Areas

There are many ways to focus your studies or research in marine biology, and it can be difficult to know where to start. The University of Washington has faculty with expertise in a diverse range of research areas related to marine biology. To help you explore these areas, we group many topics of interest into four ‘core research areas’. Click on a specific topic to find faculty who teach or research in the areas you’re interested in.

Many Marine Biologists research specific groups of organisms. How and why did they evolve? What is unique about this group of organisms? Many people have an early interest in sharks, whales and fish. Try exploring a group you aren’t as familiar with – lesser-known groups such as marine invertebrates or seaweeds may surprise you!

Marine Microbiology Salmon Sharks Fish Invertebrates Marine Mammals Seabirds

How do organisms in the marine environment move, get energy, or reproduce? How do they adapt to the stresses of their environment? How do they interact with each other? When we examine processes, we think about the physiology of an organism (i.e, how does it work?) as well as how that organism is similar to or different from other life in the ocean. This can advance our understanding of life in the sea, and may even have implications for human health or engineering.

Evolution & Adaptation Animal Behavior Genetics/Genomics

Habitats and Ecosystems

Marine life does not exist alone. It is part of a complex system of interactions with other organisms and the physical environment. Studying the ‘big picture’ through ecology or oceanography is a critical part of marine biology.

Salish Sea Ecology Tropical Ecology & Corals Oceanography Arctic Ecology Quantitative Ecology & Modeling

Changing Oceans

The oceans are constantly changing due to the natural cycles of tides or seasons to longer-term changes in global climate. Humans influence change in the oceans as societal and economic forces drive what we take out of the ocean and what we put in. Marine Biologists have an important voice in decisions about conservation and marine policy.
