Seasearch Diving

Seasearch survey Cornwall Seasearch Survey at Gull Rock near Holywell Bay

Seasearch is a national project for volunteer divers who have an interest in what they are seeing under water, who want to learn more and who want to help protect the marine environment. Cornwall Wildlife Trust is responsible for co-ordinating all Seasearch activities in the county.

 If you are a qualified diver we want to hear about the marine life you see on your dives!

The aim of Seasearch is to record marine habitats and species found around our coast, and to use the information to identify sites of specific conservation concern. The data collected helps us with our conservation work and raises public awareness of the value of our marine environment.

Once you are qualified as a Seasearch Observer any dive can be a Seasearch dive, you just fill in a simple form and send it in to us! 

How you can get involved

Seasearch in Cornwall has a network of qualified divers who participate in organised surveys and complete and send in Seasearch forms from their own recreational dives. If you would like to get involved contact us on: Training is available for volunteers; for information about the kind of training Seasearch courses provide please visit the natioanal Seasearch website.

Seasearch is fun!

It is great to dive with like minded people who are interested in marine wildlife. Many Seasearchers are keen underwater photographers and seasearch is a fantastic way to improve your marine species identification and knowledge while making new friends and having fun! 

Seasearch is important

The infomation recorded over the past 14 years of the Seasearch programme in Cornwall has been a vital tool for our marine conservation work. Without this vital work we would have far less knowledge about our coastal marine life.  Data is used to monitor changes driven by factors such as climate change, introduction of non-native marine species and effects on the environment of plastic pollution, fishing and other human activities. Seasearch data has been a driving factor in the newly expanded network of Marine Protected areas designated around our coasts and many of thses sites would not have been established without the data collected by seasearch volunteers. Increasingly the work of seasearch will be vital in monitoring the effectivness of the management of these areas.
