Big Seaweed Search
1 minute read
Our coast is home to an amazing array of seaweeds, which can tell us vital information about our climate. Get involved in the Big Seaweed Search to help monitor the impacts of climate change on our marine environment and the unique species that live there.
What is the Big Seaweed Search?
The Big Seaweed Search is a community science project that we run in partnership with the Natural History Museum.
Through it we want to learn more about some of the key seaweed species found in our waters, record where they are and find out how their distribution is changing over time. You can help us collect this vital information.

Why is seaweed important?
Seaweeds play a major role in marine ecosystems and are a vital part in the marine food chain providing nutrients and energy for other animals.
Importantly they also help mitigate the effects of climate change and store blue carbon.
As climate change is affecting our marine environment we are seeing sea temperature increases, sea level rise and ocean acidification. These changes alter the distribution of different seaweed species.
Through the Big Seaweed Survey we are recording the distribution of specific species to help us measure the impact of environmental changes.
Know your dabberweed from your wakame?
There are over 600 species of seaweed around the UK. But we just need you to help us map the distribution of 14 of them. Your survey data will help us learn more about how these seaweeds are important in preserving the health and diversity of our ocean.

How to get involved
It’s easy to take part. The Big Seaweed Search guide explains what you need to do, and provides photos to help you to identify each of the seaweeds we are focussing on. You can complete the simple survey on a mobile, tablet or computer.
The survey can be carried out at any time of year and as an individual or in groups – it's up to you.
