Dr Kat Bruce is a scientist, adventurer and expedition leader, founder of NatureMetrics, and now working for the Protected Areas Foundation. In this episode, we're going on a journey from the depths of the Amazon to the Northwest Passage, via one and a half circumnavigations of the UK in a rowing boat!

We're talking underwater magic with eDNA, or environmental DNA - the incredible scientific research technique being used around the world to monitor biodiversity, by making the invisible visible.

Kat's recommendations:

Book - Savages, by Joe Kane

Film - Ocean with David Attenborough
