The tourist brochures are clear about what we should expect from a remote tropical island: bright blue water, white sand, some exotic shells and the odd coconut tree. But the reality is usually a little bit more complicated.

In Ocean Matters, Helen Czerski explores these small, remote islands - distant specks of land that are dwarfed by the vast ocean around them. How do they form? What makes both the islands and their inhabitants so distinctive? And why are they disappearing?

With special thanks to Dr Ines Lange and Professor Chris Perry from the University of Exeter, Professor Carl Jones from the Durrell Wildlife Conservation Trust, and James Michel, Former President of the Seychelles.
