Big Seaweed Search


Region Active


Research survey




Seaweed, Marine research, Citizen science

The Big Seaweed Search first launched in 2009 under the auspices of the Marine Conservation Society and the Natural History Museum in the UK. Hundreds of people have taken part and the data gathered, alongside other research, show that the distribution of seaweeds around the UK is changing. The survey supports research on ‘three key environmental issues: rising sea temperature, the arrival and spread of non-native species of seaweeds, ocean acidification (the sea becoming more acidic because of absorbing carbon dioxide from the air.’ The website provides information about how to become involved in this citizen science project.
