Oceans represent Earth's last great unexplored wilderness.

Despite making up more than 70% of the Earth's surface, there is still much about the oceans that we do not know.

Exploring and studying them is critical to protect these valuable resources for future generations. Uncover why we need to protect the oceans, find out how to get involved and dive into cutting-edge research about life underwater.
