Introduction / About the Career
What the course/field is about
Marine Biology is the scientific study of life in oceans, seas, estuaries, and coastal environments. It combines biology, ecology, oceanography, and environmental science to research marine organisms, their behavior, habitats, and interactions with the environment, including the impact of climate change and human activities.
Historical / Global Relevance
- Oceans cover more than 70% of Earth’s surface and are vital to global climate and life.
- Marine biology has helped advance fisheries management, coral reef conservation, and marine ecosystem protection.
- Globally, marine biologists play a key role in biodiversity conservation, climate research, and sustainable use of ocean resources.
