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.

The Museum's scientists study marine specimens from around the globe, from tiny fossils to vast whale skeletons.

This scientific research informs debates on issues including climate change, ocean acidification and plastics in the sea.

Uncover why we need to protect the oceans, find out how to get involved and and dive into cutting-edge research about life underwater.
