Mud on the seabed and the diverse, weird and wonderful invertebrates who live in it are having their climate moment, according to Marine Biologist Dr Ceri Lewis.

Based at the University of Exeter – Ceri is part of the five-year Convex Seascape Survey researching how a healthy ocean can help fight climate change. She’s passionate about worms – from microscopic to 3 metres long - and how they influence carbon stores on the seabed. 

Ceri also talks about her latest scientific trip to the Galapagos where she’s studying the effects of the exponential growth in microplastics on our marine life.
