Contribute to our database and help us monitor environmental changes and manage these vital resources.

Seaweed search for DofE

We need people to record the seaweeds found on our coastline to help us research rising sea temperatures and the impact of the sea becoming more acidic as a result of absorbing carbon dioxide from the air.

You can do this activity on any seashore in the British Isles. All shores are important for the research, but you will find more seaweeds on shores with hard structures like rocks, sea walls and piers.

Your findings will contribute to a real MCS and Natural History Museum scientific research project.

Big Seaweed Search

We started working with the Natural History Museum on the Big Seaweed Search in 2007. Since then, hundreds of people have taken part.

The data collected provides vital information about environmental changes affecting seaweeds. As a result, we can better understand and protect this vitally-important habitat.
